一、前期问题
1、系统环境
2、给虚拟机中的Debian系统安装VIM 和SSH
如果你的机子出现下面的提示
 就说明你要挂载你的CD/DVD了，又或者是自己改一下源地址，关于如何设置自己的系统找到最快的源，请参考http://www.opsers.org/2010_03_851.html。我们用光盘，来的快。虚拟机一定要注意，先把虚拟光驱给连上哦，不然会出现找不到媒体的错误提示哦！
然后我们就用apt-get install ssh vim来安装这两个软件吧。
3、检查系统中是否已经安装了我们正准备安装的软件
我们主要检查一下apache mysql php mcrypt imagick这些软件是不是已经安装在我们的系统中了，如果有的话，就删除，记得，一定要连同配置文件一起删除。
apt-get remove xxx这是删除软件
dpkg –force-all –P xxx这是删除配置文件
如果说，你的系统是自己安装的虚拟机，只安装了基本系统，没有安装其它软件的话，基本上不会安装上述软件。但为了安全，还是自己先检测一下吧。
二、安装源码编译环境
我们可以通过SSH的远程工具来连接到我们的Debian系统上，进行下面的操作。
apt-get install build-essential
注意，在下面的文章中我们还需要安装libncurses5-dev libxml2-dev libssl-dev ibcurl4-openssl-dev libjpeg62-dev libpng12-dev libfreetype6-dev libsasl2-dev autoconf libpcre3-dev这几个软件库，至于为什么要安装，大家会在后面的文章中找到答案。
所以，可以一起安装，也可以根据需要，缺什么安装什么。
apt-get install build-essential libncurses5-dev libxml2-dev libssl-dev libcurl4-openssl-dev libjpeg62-dev libpng12-dev libfreetype6-dev libsasl2-dev autoconf libpcre3-dev libperl-dev
三、下载所需软件
mkdir /soft
cd /soft
vim down.sh
内容如下
wget http://blog.s135.com/soft/linux/nginx_php/nginx/nginx-0.8.46.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/php/php-5.2.14.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/phpfpm/php-5.2.14-fpm-0.5.14.diff.gz
wget http://blog.s135.com/soft/linux/nginx_php/mysql/mysql-5.5.3-m3.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/libiconv/libiconv-1.13.1.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/mcrypt/libmcrypt-2.5.8.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/mcrypt/mcrypt-2.6.8.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/memcache/memcache-2.2.5.tgz
wget http://blog.s135.com/soft/linux/nginx_php/mhash/mhash-0.9.9.9.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/pcre/pcre-8.10.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/eaccelerator/eaccelerator-0.9.6.1.tar.bz2
wget http://blog.s135.com/soft/linux/nginx_php/pdo/PDO_MYSQL-1.0.2.tgz
wget http://blog.s135.com/soft/linux/nginx_php/imagick/ImageMagick.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/imagick/imagick-2.3.0.tgz
设置可执行权限
chmod +x down.sh
开始下载
./down.sh
四、安装软件
1、编译安装PHP 5.2.14所需的支持库：
tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure –prefix=/usr/local
make && make install
cd ..
tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8
/sbin/ldconfig
cd libltdl/
./configure –enable-ltdl-install
make && make install
cd ..
./configure
make && make install
cd ..
tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make && make install
cd ..
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make && make install
cd ..
2、编译安装MySQL 5.5.3-m3
mysql安装前需要安装 libncurses5-dev
apt-get install libncurses5-dev
否则就会出现下面的错误
checking for termcap functions library… configure: error: No curses/termcap library found
处理完上面的内容，下面就可以开始编译mysql了
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.5.3-m3.tar.gz
cd mysql-5.5.3-m3/
./configure –prefix=/usr/local/webserver/mysql/ –enable-assembler –with-extra-charsets=complex –enable-thread-safe-client –with-big-tables –with-readline –with-ssl –with-embedded-server –enable-local-infile –with-plugins=partition,innobase,myisammrg
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cd ..
①、创建MySQL数据库存放目录
mkdir -p /data0/mysql/3306/data/
mkdir -p /data0/mysql/3306/binlog/
mkdir -p /data0/mysql/3306/relaylog/
chown -R mysql:mysql /data0/mysql/
②、以mysql用户帐号的身份建立数据表：
/usr/local/webserver/mysql/bin/mysql_install_db –basedir=/usr/local/webserver/mysql –datadir=/data0/mysql/3306/data –user=mysql
一定要注意看提示，是否正常
 ③、创建my.cnf配置文件：
vim /data0/mysql/3306/my.cnf
内容如下：
[client]
character-set-server = utf8
port = 3306
socket = /tmp/mysql.sock
[mysqld]
character-set-server = utf8
replicate-ignore-db = mysql
replicate-ignore-db = test
replicate-ignore-db = information_schema
user = mysql
port = 3306
socket = /tmp/mysql.sock
basedir = /usr/local/webserver/mysql
datadir = /data0/mysql/3306/data
log-error = /data0/mysql/3306/mysql_error.log
pid-file = /data0/mysql/3306/mysql.pid
open_files_limit = 10240
back_log = 600
max_connections = 5000
max_connect_errors = 6000
table_cache = 614
external-locking = FALSE
max_allowed_packet = 32M
sort_buffer_size = 1M
join_buffer_size = 1M
thread_cache_size = 300
#thread_concurrency = 8
query_cache_size = 512M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M
max_heap_table_size = 246M
long_query_time = 3
log-slave-updates
log-bin = /data0/mysql/3306/binlog/binlog
binlog_cache_size = 4M
binlog_format = MIXED
max_binlog_cache_size = 8M
max_binlog_size = 1G
relay-log-index = /data0/mysql/3306/relaylog/relaylog
relay-log-info-file = /data0/mysql/3306/relaylog/relaylog
relay-log = /data0/mysql/3306/relaylog/relaylog
expire_logs_days = 30
key_buffer_size = 256M
read_buffer_size = 1M
read_rnd_buffer_size = 16M
bulk_insert_buffer_size = 64M
myisam_sort_buffer_size = 128M
myisam_max_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover
interactive_timeout = 120
wait_timeout = 120
skip-name-resolve
#master-connect-retry = 10
slave-skip-errors = 1032,1062,126,1114,1146,1048,1396
#master-host = 192.168.1.2
#master-user = username
#master-password = password
#master-port = 3306
server-id = 1
innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 512M
innodb_data_file_path = ibdata1:256M:autoextend
innodb_file_io_threads = 4
innodb_thread_concurrency = 8
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 128M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
innodb_file_per_table = 0
#log-slow-queries = /data0/mysql/3306/slow.log
#long_query_time = 10
[mysqldump]
quick
max_allowed_packet = 32M
④、创建管理MySQL数据库的shell脚本：
vim /data0/mysql/3306/mysql
内容如下
#!/bin/sh
mysql_port=3306
mysql_username=”admin”
mysql_password=”12345678″
function_start_mysql()
{
printf “Starting MySQL…\n”
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe –defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
}
function_stop_mysql()
{
printf “Stoping MySQL…\n”
/usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}
function_restart_mysql()
{
printf “Restarting MySQL…\n”
function_stop_mysql
sleep 5
function_start_mysql
}
function_kill_mysql()
{
kill -9 $(ps -ef | grep ‘bin/mysqld_safe’ | grep ${mysql_port} | awk ‘{printf $2}’)
kill -9 $(ps -ef | grep ‘libexec/mysqld’ | grep ${mysql_port} | awk ‘{printf $2}’)
}
if [ "$1" = "start" ]; then
function_start_mysql
elif [ "$1" = "stop" ]; then
function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
printf “Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n”
fi
⑤、赋予shell脚本可执行权限：
chmod +x /data0/mysql/3306/mysql ⑥、启动MySQL：
/data0/mysql/3306/mysql start
稍等片刻，用netstat –ntlp |grep 3306就能看到mysqld服务启动了
⑦、设置MySql root用户的密码(记住，后面用到)
/usr/local/webserver/mysql/bin/mysqladmin -u root password ’123456789′
⑧、通过命令行登录管理MySQL服务器（提示输入密码时，输入刚才设置的密码123456789）
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
这时候到mysql命令行中
 ⑨、输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）
GRANT ALL PRIVILEGES ON *.* TO ‘admin’@'localhost’ IDENTIFIED BY ’12345678′;
GRANT ALL PRIVILEGES ON *.* TO ‘admin’@’127.0.0.1′ IDENTIFIED BY ’12345678′;
quit;
⑩、停止MySQL
/data0/mysql/3306/mysql stop
3、编译安装PHP（FastCGI模式）
在编译安装前，我们要先来了解点小知识
如apt-cache search “freetype”
这个命令是在源中查找和freetype有关的所有软件，再根据软件包的描述，找你自己需要的软件，然后就可以用下面的命令进行安装
apt-get install libfreetype6-dev
当然是要根据错误提示来查找相关的软件。
我们在编译过程中，缺什么，就补什么，这个也算是一种解决问题的思路。希望能给大家带来点帮助！
出现下面的错误提示
checking for xml2-config… no
checking for xml-config… no
configure: error: XML configuration could not be found
安装
apt-get install libxml2-dev
出现
configure: error: Cannot find OpenSSL’s <evp.h>
安装
apt-get install libssl-dev
出现
configure: error: Please reinstall the libcurl distribution -
easy.h should be in <curl-dir>/include/curl/
安装
apt-get install libcurl4-openssl-dev
出现
configure: error: libjpeg.(a|so) not found.
安装
apt-get install libjpeg62-dev
出现
configure: error: libpng.(a|so) not found.
安装
apt-get install libpng12-dev
出现
configure: error: freetype.h not found.
安装
apt-get install libfreetype6-dev
出现
configure: error: sasl.h not found!
安装
apt-get install libsasl2-dev
所以，我们进行前，要把上面的软件全部安装上，根据Debain的版本不同，安装的包可能不同，但是思路就是这样的，我们的系统需要安装下面的软件
apt-get install libxml2-dev libcurl4-openssl-dev libjpeg62-dev libpng12-dev libfreetype6-dev libsasl2-dev
tar zxvf php-5.2.14.tar.gz
gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
cd php-5.2.14/
./configure –prefix=/usr/local/webserver/php –with-config-file-path=/usr/local/webserver/php/etc –with-mysql=/usr/local/webserver/mysql –with-mysqli=/usr/local/webserver/mysql/bin/mysql_config –with-iconv-dir=/usr/local –with-freetype-dir –with-jpeg-dir –with-png-dir–with-zlib –with-libxml-dir=/usr –enable-xml –disable-rpath –enable-discard-path –enable-safe-mode –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –with-curlwrappers –enable-mbregex –enable-fastcgi –enable-fpm –enable-force-cgi-redirect–enable-mbstring –with-mcrypt –with-gd –enable-gd-native-ttf –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-ldap –with-ldap-sasl –with-xmlrpc –enable-zip –enable-soap
make ZEND_EXTRA_LIBS=’-liconv’
make install
cp php.ini-dist /usr/local/webserver/php/etc/php.ini
cd ..
4、编译安装PHP5扩展模块
这个在configure的时候会提示
-bash: ./configure: No such file or directory
所以我们要先安装autoconf
apt-get install autoconf
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/webserver/php/bin/phpize
./configure –with-php-config=/usr/local/webserver/php/bin/php-config
make && make install
cd ..
tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/usr/local/webserver/php/bin/phpize
./configure –enable-eaccelerator=shared –with-php-config=/usr/local/webserver/php/bin/php-config
make && make install
cd ..
tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/webserver/php/bin/phpize
./configure –with-php-config=/usr/local/webserver/php/bin/php-config –with-pdo-mysql=/usr/local/webserver/mysql
make && make install
cd ..
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make && make install
cd ..
tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/usr/local/webserver/php/bin/phpize
./configure –with-php-config=/usr/local/webserver/php/bin/php-config
make && make install
cd ..
5、修改php.ini文件
手工修改：查找/usr/local/webserver/php/etc/php.ini中的extension_dir = “./”
修改为extension_dir = “/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/”
并在此行后增加以下几行，然后保存：
extension = “memcache.so”
extension = “pdo_mysql.so”
extension = “imagick.so”
再查找output_buffering = Off
修改为output_buffering = On
再查找cgi.fix_pathinfo=0
把前面的注释去掉，防止Nginx文件类型错误解析漏洞。
自动修改：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php.ini文件的修改：
sed -i ‘s#extension_dir = “./”#extension_dir = “/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/”\nextension = “memcache.so”\nextension = “pdo_mysql.so”\nextension = “imagick.so”\n#’ /usr/local/webserver/php/etc/php.ini
sed -i ‘s#output_buffering = Off#output_buffering = On#’ /usr/local/webserver/php/etc/php.ini
sed -i “s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g” /usr/local/webserver/php/etc/php.ini
sed -i “s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g” /usr/local/webserver/php/etc/php.ini
6、配置eAccelerator加速PHP：
mkdir -p /usr/local/webserver/eaccelerator_cache
vim /usr/local/webserver/php/etc/php.ini
到配置文件的最末尾，加上以下配置信息：
[eaccelerator]
zend_extension=”/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so”
eaccelerator.shm_size=”64″
eaccelerator.cache_dir=”/usr/local/webserver/eaccelerator_cache”
eaccelerator.enable=”1″
eaccelerator.optimizer=”1″
eaccelerator.check_mtime=”1″
eaccelerator.debug=”0″
eaccelerator.filter=”"
eaccelerator.shm_max=”0″
eaccelerator.shm_ttl=”3600″
eaccelerator.shm_prune_period=”3600″
eaccelerator.shm_only=”0″
eaccelerator.compress=”1″
eaccelerator.compress_level=”9″
7、创建www用户和组，以及供debian.freeopens.com虚拟主机使用的目录
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www
8、创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：
rm -f /usr/local/webserver/php/etc/php-fpm.conf
vim /usr/local/webserver/php/etc/php-fpm.conf
输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的<value name=”display_errors”>0</value>改为<value name=”display_errors”>1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）：

9、启动php-cgi进程，监听127.0.0.1的9000端口，进程数为128（如果服务器内存小于3GB，可以只开启64个进程），用户为www：
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。
启动的时候出现下面的错误(是内在不足导致的，在文章的结尾优化后，就不会有这样的问题了)
Starting php_fpm eAccelerator: Could not allocate 67108864 bytes, the maximum size the kernel allows is 33554432 bytes. Lower the amount of memory request or increase the limit in /proc/sys/kernel/shmmax.
PHP Warning: [eAccelerator] Can not create shared memory area in Unknown on line 0
PHP Fatal error: Unable to start eAccelerator module in Unknown on line 0
failed
10、安装Nginx
①、安装Nginx所需的pcre库：
tar zxvf pcre-8.10.tar.gz
cd pcre-8.10/
./configure
make && make install
cd ..
②、安装Nginx
tar zxvf nginx-0.8.46.tar.gz
cd nginx-0.8.46/
./configure –user=www –group=www –prefix=/usr/local/webserver/nginx –with-http_stub_status_module –with-http_ssl_module
make && make install
cd ..
③、创建Nginx日志目录
mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs
④、创建Nginx配置文件
I、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：
rm -f /usr/local/webserver/nginx/conf/nginx.conf
vim /usr/local/webserver/nginx/conf/nginx.conf
内容如下：
user www www;
worker_processes 8;
error_log /data1/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;
#charset gb2312;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
#limit_zone crawler $binary_remote_addr 10m;
server
{
listen 80;
server_name www.freeopens.com;
index index.html index.htm index.php;
root /data0/htdocs/www;
#limit_conn crawler 20;
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 1h;
}
log_format access ‘$remote_addr – $remote_user [$time_local] “$request” ‘
‘$status $body_bytes_sent “$http_referer” ‘
‘”$http_user_agent” $http_x_forwarded_for’;
access_log /data1/logs/access.log access;
}
}
II、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件：
vim /usr/local/webserver/nginx/conf/fcgi.conf
内容如下
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with –enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
⑤、启动Nginx
ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx
会出现如下的错误提示
/usr/local/webserver/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory
我们需要安装
apt-get install libpcre3-dev
五、配置开机自动启动Nginx + PHP + Mysql
vim /etc/rc.local
把下面的内容增加到exit 0的上面，这个地方一定要注意，是在exit 0的上面，放到下面的话，就不会启动了！！
/data0/mysql/3306/mysql start
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx
六、相关软件的重新启动
如果说你改了nginx的配置文件，就要用下面的命令，使配置生效
/usr/local/webserver/nginx/sbin/nginx -t 检查参数
对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可
/usr/local/webserver/nginx/sbin/nginx -s reload 平滑重启
对于Nginx 0.8.x之前的版本，执行下面的命令
kill -HUP `cat /usr/local/webserver/nginx/nginx.pid` 平滑重启
如果说你改了php.ini就要用下面的命令，使配置生效
/usr/local/webserver/php/sbin/php-fpm reload 重新加载 mysql数据库重新启动
/data0/mysql/3306/mysql restart
七、优化Linux内核参数
vim /etc/sysctl.conf
在末尾增加以下内容
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535
使配置立即生效：
/sbin/sysctl -p
八、在小内存服务器（256M）上的配置优化
1、Nginx 的主配置文件（nginx.conf）优化
vim /usr/local/webserver/nginx/conf/nginx.conf
根据下面的内容进行相应的修改和增加
#Nginx每个进程耗费10M~12M内存，这里只开启一个Nginx进程，节省内存。
worker_processes 1;
#对网页文件、CSS、JS、XML等启动gzip压缩，减少数据传输量，提高访问速度。
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
location ~ .*\.(php|php5)?$
{
#将Nginx与FastCGI的通信方式由TCP改为Unix Socket。TCP在高并发访问下比Unix Socket稳定，但Unix Socket速度要比TCP快。
fastcgi_pass unix:/tmp/php-cgi.sock;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
#博客的图片较多，更改较少，将它们在浏览器本地缓存15天，可以提高下次打开我博客的页面加载速度。
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 15d;
}
#博客会加载很多JavaScript、CSS，将它们在浏览器本地缓存1天，访问者在看完一篇文章或一页后，再看另一篇文件或另一页的内容，无需从服务器再次下载相同的JavaScript、CSS，提高了页面显示速度。
location ~ .*\.(js|css)?$
{
expires 1d;
}
2、PHP（FastCGI）的配置优化
php.ini 配置文件中关于eAcelerator的优化。只使用1M共享内存，删除所有在最后3600秒内无法存取的脚本缓存，用磁盘辅助进行缓存。
vim /usr/local/webserver/php/etc/php.ini
根据内容增加或者修改
eaccelerator.shm_size=”1″
eaccelerator.shm_ttl=”3600″
eaccelerator.shm_prune_period=”3600″
eaccelerator.keys = “disk_only”
eaccelerator.sessions = “disk_only”
eaccelerator.content = “disk_only”
3、php-fpm.conf 的配置优化
vim /usr/local/webserver/php/etc/php-fpm.conf
一是修改以下一行，将启动的php-cgi进程数由原来的128个改为5个：
<value name=”max_children”>5</value>
二是修改以下一行，将TCP模式改为Unix Socket模式：
<value name=”listen_address”>/tmp/php-cgi.sock</value>
4、MySQL配置优化vi /data0/mysql/3306/my.cnf
根据自己的情况改吧
[client]
port = 3306
socket = /tmp/mysql.sock
[mysql]
prompt=”(\u:s135:)[\d]> ”
no-auto-rehash
[mysqld]
user = mysql
port = 3306
socket = /tmp/mysql.sock
basedir = /usr/local/webserver/mysql
datadir = /usr/local/webserver/mysql/data
open_files_limit = 600
back_log = 20
max_connections = 100
max_connect_errors = 200
table_cache = 60
external-locking = FALSE
max_allowed_packet = 16M
sort_buffer_size = 128K
join_buffer_size = 128K
thread_cache_size = 10
thread_concurrency = 8
query_cache_size = 0M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default_table_type = MyISAM
thread_stack = 192K
transaction_isolation = READ-UNCOMMITTED
tmp_table_size = 512K
max_heap_table_size = 32M
/usr/local/webserver/mysql/data/slow.log
/usr/local/webserver/mysql/data/error.log
long_query_time = 1
log_long_format
server-id = 1
#log-bin = /usr/local/mysql/data/binlog
binlog_cache_size = 2M
max_binlog_cache_size = 4M
max_binlog_size = 512M
expire_logs_days = 7
key_buffer_size = 4M
read_buffer_size = 1M
read_rnd_buffer_size = 2M
bulk_insert_buffer_size = 2M
myisam_sort_buffer_size = 4M
myisam_max_sort_file_size = 10G
myisam_max_extra_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover
[mysqldump]
quick
max_allowed_packet = 16M
九、每天定时切割Nginx日志
1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh
vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
输入以下内容
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path=”/usr/local/webserver/nginx/logs/”
mkdir -p ${logs_path}$(date -d “yesterday” +”%Y”)/$(date -d “yesterday” +”%m”)
mv ${logs_path}access.log ${logs_path}$(date -d “yesterday” +”%Y”)/$(date -d “yesterday” +”%m”)/access_$(date -d “yesterday” +”%Y%m%d”).log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`
2、设置crontab，每天凌晨00:00切割nginx访问日志
crontab -e
增加以下内容
00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
