memcache缓存服务器(nginx php memcache mysql)
环境:
192.168.1.23 nginx+php
192.168.1.28 memcache
192.168.1.27 mysql
一、安装 nginx (192.168.1.23)
1、解压 zlib 和pcre 不需要编译,只需要解压就行。
[root@localhost ~]# tar zxf zlib-1.2.8.tar.gz
[root@localhost ~]# tar zxf pcre-8.39.tar.gz
2、安装依赖包
[root@localhost ~]#yum -y install gcc gcc-c++ make libtool openssl openssl-devel
3、解压源码包
①下载 nginx 的源码包: http://nginx.org/download
[root@localhost ~]# tar zxf nginx-1.14.0.tar.gz
[root@localhost ~]# cd nginx-1.14.0/
[root@localhost nginx-1.14.0]# groupadd www
[root@localhost nginx-1.14.0]# useradd -g www www -s /sbin/nologin
[root@localhost nginx-1.14.0]#./configure --prefix=/usr/local/nginx1.14 \
--with-http_dav_module --with-http_stub_status_module \
--with-http_addition_module --with-http_sub_module \
--with-http_flv_module --with-http_mp4_module \
--with-pcre=/root/pcre-8.39 --with-zlib=/root/zlib-1.2.8 \
--with-http_ssl_module --with-http_gzip_static_module --user=www \
--group=www
[root@localhost nginx-1.14.0]# make && make install
[root@localhost nginx-1.14.0]# ln -s /usr/local/nginx1.14/sbin/nginx /usr/local/sbin/
[root@localhost nginx-1.14.0]# nginx -t
nginx: the configuration file /usr/local/nginx1.14/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx1.14/conf/nginx.conf test is successful
[root@localhost nginx-1.14.0]# nginx
[root@localhost nginx-1.14.0]# netstat -anpt | grep nginx
4、关闭防火墙或者开启端口
[root@localhost nginx-1.14.0]# systemctl stop firewalld.service
5、安装 php
①安装 libmcrypt
[root@localhost ~]# tar zxf libmcrypt-2.5.7.tar.gz
[root@localhost ~]# cd libmcrypt-2.5.7/
[root@localhost libmcrypt-2.5.7]# ./configure --prefix=/usr/local/libmcrypt && make && make install
②安装依赖包
[root@localhost libmcrypt-2.5.7]# yum -y install libxml2-devel libcurl-devel openssl-devel bzip2-devel
[root@localhost ~]# tar zxf php-5.6.27.tar.gz
[root@localhost ~]# cd php-5.6.27/
[root@localhost php-5.6.27]#./configure --prefix=/usr/local/php5.6 --with-mysql=mysqlnd \
--with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-openssl --enable-fpm --enable-sockets \
--enable-sysvshm --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib \
--with-libxml-dir=/usr --enable-xml --with-mhash --with-mcrypt=/usr/local/libmcrypt \
--with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 \
--enable-maintainer-zts
[root@localhost php-5.6.27]#make && make install
[root@localhost php-5.6.27]# cp php.ini-production /etc/php.ini
③修改/etc/php.ini 文件,将 short_open_tag 修改为 on
[root@localhost php-5.6.27]#vim /etc/php.ini
;short_open_tag 改成 short_open_tag=0 //第151行(支持 php 短标签 )
④创建 php-fpm 服务启动脚本:
[root@localhost php-5.6.27]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-5.6.27]# chmod +x /etc/init.d/php-fpm
[root@localhost php-5.6.27]# chkconfig --add php-fpm
[root@localhost php-5.6.27]# chkconfig php-fpm on
⑤提供 php-fpm 配置文件并编辑
[root@localhost php-5.6.27]# cp /usr/local/php5.6/etc/php-fpm.conf.default /usr/local/php5.6/etc/php-fpm.conf
[root@localhost php-5.6.27]#vim /usr/local/php5.6/etc/php-fpm.conf
第25行去掉; pid = run/php-fpm.pid
第164行 listen =127.0.0.1:9000
第235行 pm.max_children = 300
第240行 pm.start_servers = 10
第245行 pm.min_spare_servers = 10
第250行 pm.max_spare_servers =50
⑥启动 php-fpm 服务
[root@localhost php-5.6.27]# service php-fpm start
Starting php-fpm done
[root@localhost php-5.6.27]# netstat -anpt | grep php-fpm
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 52269/php-fpm: mast
二、安装MySQL省略(192.168.1.27)
三、安装 memcached 服务端 (192.168.1.28)
1、首先先安装 memcached 依赖库 libevent
[root@localhost ~]# tar zxf libevent-2.0.22-stable.tar.gz
[root@localhost ~]# cd libevent-2.0.22-stable/
[root@localhost libevent-2.0.22-stable]# ./configure
[root@localhost libevent-2.0.22-stable]# make && make install
①安装 memcached
[root@localhost ~]# tar zxf memcached-1.4.33.tar.gz
[root@localhost ~]# cd memcached-1.4.33/
[root@localhost memcached-1.4.33]# ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local
[root@localhost memcached-1.4.33]# make && make install
②检测是否成功安装
[root@localhost memcached-1.4.33]# ls /usr/local/memcached/bin/memcached
/usr/local/memcached/bin/memcached
③为系统环境变量 LD_LIBRARY_PATH 增加新的目录
[root@localhost memcached-1.4.33]# vim ~/.bash_profile
添加:
MEMCACHED_HOME=/usr/local/memcached
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$MEMCACHED_HOME/lib
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# /usr/local/memcached/bin/memcached -d -m 2048 -l 192.168.1.28 -p 11211 -u root -c 10240 -P /usr/local/memcached/memcached.pid
[root@localhost ~]# netstat -anpt |grep memcached
tcp 0 0 192.168.1.28:11211 0.0.0.0:* LISTEN 64362/memcached
④刷新用户环境变量:
[root@localhost ~]# source ~/.bash_profile
⑤编写 memcached 服务启停脚本
[root@localhost memcached-1.4.33]#vi /etc/init.d/memcached
添加:
#!/bin/sh
#
# pidfile: /usr/local/memcached/memcached.pid
# memcached_home: /usr/local/memcached
# chkconfig: 35 21 79
# description: Start and stop memcached Service
# Source function library
. /etc/rc.d/init.d/functions
RETVAL=0
prog="memcached"
basedir=/usr/local/memcached
cmd=${basedir}/bin/memcached
pidfile="$basedir/${prog}.pid"
#interface to listen on (default: INADDR_ANY, all addresses)
ipaddr="192.168.1.28"
#listen port
port=11211
#username for memcached
username="root"
#max memory for memcached,default is 64M
max_memory=2048
#max connections for memcached
max_simul_conn=10240
start() {
echo -n $"Starting service: $prog"
$cmd -d -m $max_memory -u $username -l $ipaddr -p $port -c $max_simul_conn -P $pidfile
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog
}
stop() {
echo -n $"Stopping service: $prog "
run_user=$(whoami)
pidlist=$(ps -ef | grep $run_user | grep memcached | grep -v grep | awk '{print($2)}')
for pid in $pidlist
do
kill -9 $pidif [ $? -ne 0 ]; then
return 1
fi
done
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo "Usage: $0 {start|stop|restart|status}"
exit 1
esac
exit $RETVAL
[root@localhost ~]# chmod +x /etc/init.d/memcached
[root@localhost ~]# chkconfig --add memcached
[root@localhost ~]# chkconfig memcached on
2、配置 nginx.conf 文件(在 nginx 主机操作)
①修改配置文件
[root@localhost ~]# vi /usr/local/nginx1.14/conf/nginx.conf
全删掉然后添加:
user www www;
worker_processes 2;
worker_cpu_affinity 01 10;
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;pid logs/nginx.pid;

#
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}
}
}
②重启 nginx 服务
[root@localhost php-5.6.27]# nginx -s reload
[root@localhost php-5.6.27]# netstat -anpt | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 15512/nginx: worker
③生成一个 php 测试页
[root@localhost ~]# cd /usr/local/nginx1.14/html/
[root@localhost html]# vim test1.php
添加:
3、memcache 客户端(在 nginx、php 服务器操作)
①安装memcache客户端
[root@localhost ~]# tar zxf memcache-3.0.8.tgz
[root@localhost ~]# cd memcache-3.0.8/
[root@localhost memcache-3.0.8]# /usr/local/php5.6/bin/phpize
[root@localhost memcache-3.0.8]#./configure --enable-memcache --with-php-config=/usr/local/php5.6/bin/php-config
[root@localhost memcache-3.0.8]# make && make install
②安装完后会有类似这样的提示:
Installing shared extensions:
/usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/
③把这个记住,然后修改 php.ini
[root@localhost memcache-3.0.8]# vim /etc/php.ini
添加:
extension=/usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/memcache.so
④重启 php-fpm 服务
[root@localhost memcache-3.0.8]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm done
4、测试:
①检查 php 扩展是否正确安装 查询结果中是否有 memcache 项
②创建 phpinfo()页面,查询 session 项下面的 Registered save handlers 值中是否有 memcache
项
③浏览器访问 test1.php
④测试代码:
[root@localhost memcache-3.0.8]# cd /usr/local/nginx1.14/html/
[root@localhost html]# vim test2.php
添加:
