　　 4、安装Google-perftools (使用tcmalloc 加速 mysql 和 nginx)
　　centos 》 nginx 》gperftools》libunwind 依赖顺序， 先安装libunwind



cd /usr/local/src
wget  -c http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz >libunwind-1.1.tar.gz
tar zxf libunwind-1.1.tar.gz
cd libunwind-1.1
./configure --enable-shared
make && make install

　　安装google-perftools



cd /usr/local/src
wget -c ftp://ftp.tw.freebsd.org/pub/ports/distfiles/gperftools-2.1.tar.gz
#wget -c http://gperftools.googlecode.com/files/google-perftools-2.1.tar.gz(现在googlecode.com被封了)
tar -vxzf gperftools-2.1.tar.gz
cd gperftools-2.1
./configure \
--prefix=/usr/local/gperftools \
--disable-cpu-profiler \
--enable-shared \
--disable-heap-profiler \
--disable-heap-checker \
--disable-dependency-tracking \
--enable-frame-pointers
make && make install

　　更新，使动态链接库能够被系统共享



/sbin/ldconfig
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
ldconfig

　　 5、安装mysql (需要 cmake ncurses-devel bison库)
　　安装ncurses



cd /usr/local/src
wget -c ftp://ftp.gnu.org/pub/gnu/ncurses/ncurses-5.9.tar.gz
tar zxf ncurses-5.9.tar.gz
cd ncurses-5.9

tar zvxf bison-3.0.1.tar.gz
cd bison-3.0.1
./configure
make && make install

　　创建mysql需要的目录、配置用户和用户组



groupadd mysql
useradd -g mysql mysql
mkdir -p /data/mysql
chown -R mysql:mysql /data/mysql

　　安装msyql



wget -c http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.25.tar.gz
tar zxf mysql-5.6.25.tar.gz
cd mysql-5.6.25
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DSYSCONFDIR=/etc/ \
-DWITH_SSL=yes \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_READLINE=on
make && make install

　　配置mysql



ln -s /usr/local/mysql/lib/lib* /usr/lib/
cd /usr/local/mysql
./scripts/mysql_install_db --basedir=/usr/local/mysql/ --datadir=/data/mysql/ --user=mysql
cp ./support-files/my-default.cnf /etc/my.cnf
vim /etc/my.cnf
在[client]下添加一行
default-character-set = utf8
在[mysqld]下添加一行
character-set-server = utf8

　　
　　启动配置



设置mysql开机自动启动服务
cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 345 mysqld on
修改服务配置文件
vim /etc/rc.d/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql
启动mysqld服务
service mysqld start
数据库初始化及修改root密码(root初始密码为空)
./bin/mysql_secure_installation
软连接mysql
ln -s /opt/mysql/bin/mysql /bin　
重启centos后，尝试用root连接mysql
mysql -u root -p
status;

　　使用tcmalloc优化mysql ( 需要安装google-perftools)
修改MySQL启动脚本（根据你的MySQL安装位置而定）



vim /usr/local/mysql/bin/mysqld_safe
在#executing mysqld_safe的下一行，加上：
export LD_PRELOAD=/usr/local/gperftools/lib/libtcmalloc.so
重启服务，查看tcmalloc是否生效 (第二条命令显示即生效)
service mysqld restart
lsof -n | grep tcmalloc
如果显示以下类似的信息，即表示tcmalloc生效
lsof -n|grep tcmalloc
mysqld     1824   mysql  mem       REG      253,0  1853008     801969 /usr/local/gperftools/lib/libtcmalloc.so.4.1.2

　　
　　
　　 6、安装Nginx
　　创建账户



cd /usr/local/src
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
ulimit -SHn 65535

　　安装pcre



cd /usr/local/src
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.35.tar.gz
tar zxvf pcre-8.35.tar.gz
cd pcre-8.35
./configure --prefix=/usr/local/
make && make install

　　安装nginx



wget http://nginx.org/download/nginx-1.7.1.tar.gz
tar zxvf nginx-1.7.1.tar.gz
cd nginx-1.7.1
vim ./src/core/nginx.h
修改NGINX_VERSION为你希望显示的版号
修改NGINX_VER为你希望显示的名称
修改NGINX_VAR 为你希望显示的名称

　　编译安装



./configure \
--user=www \
--group=www \
--prefix=/usr/local/nginx \
--conf-path=/etc/nginx/nginx.conf \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--with-google_perftools_module \
--with-http_secure_link_module \
--with-pcre=/usr/local/src/pcre-8.35 \
--with-http_realip_module \
--with-http_image_filter_module
make && make install

　　配置\修改 nginx.conf ，令nginx可以google-perftools实现加速



vim /etc/nginx/nginx.conf
修改前面几行为：
user www www;
worker_processes 8;#这个要看你的处理器的数量了
error_log logs/error.log crit;
pid logs/nginx.pid;
google_perftools_profiles /tmp/tcmalloc/;
events{
use epoll;
worker_connections 65535;
}
测试和运行
cd /usr/local/nginx/
./sbin/nginx -t

　　如果显示下面信息，即表示配置没问题
nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /opt/nginx/conf/nginx.conf test is successful

输入代码运行nginx服务



./sbin/nginx
ps au|grep nginx

　　如果显以类似下面的信息，即表示nginx已经启动
root     30038  0.0  0.0   5980   740 pts/0    S+   00:12   0:00 grep nginx
输入代码检测是否支持加速
lsof -n | grep tcmalloc
如果显示类似下面的信息，即表示支持tcmalloc加速 (mysqld和nginx两个线程都支持)



mysqld    8297 mysql  mem       REG      253,0  1853334     274527 /usr/local/gperftools/lib/libtcmalloc.so.4.1.2
