Apache+php+memcache集群搭建

实验环境:RHEL7.0  server1.example.com  172.25.254.1

                                server2.example.com  172.25.254.2

实验前提:已经编译安装完成php与nginx,具体内容可参考博客前边内容:。

实验内容:1.memcache安装

                 2.编译安装memcache使其支持php

                 3.修改php配置文件并配置memcache的测试页

                 4.测试

安装包:memcache-2.2.5.tgz 


1.memcache安装(memcache的端口号是11211)

[root@server1 ~]# yum install memcached -y

[root@server1 ~]# /etc/init.d/httpd start

[root@server1 ~]# /etc/init.d/memcached start

[root@server1 ~]# curl -I localhost

HTTP/1.1 200 OK

2.编译安装memcache使其支持php

[root@server1 mnt]# php -m |grep memcache     ###  可以看到php不支持memcached

[root@server1 ~]# cd /mnt/

[root@server1 mnt]# ls

memcache-2.2.5.tgz

[root@server1 mnt]# tar -zxf memcache-2.2.5.tgz   ###解压tar zxf  memcache-2.2.5.tgz

[root@server1 mnt]# cd memcache-2.2.5     ###进入解压目录

[root@server1 memcache-2.2.5]# ls

[root@server1 memcache-2.2.5]# phpize    ##会自动生成configure

Configuring for:

PHP Api Version:         20131106

Zend Module Api No:      20131226

Zend Extension Api No:   220131226

[root@server1 memcache-2.2.5]# yum install libtool -y

[root@server1 memcache-2.2.5]# ./configure \

> --prefix=/usr/local/lnmp/php/modules \

> --enable-memcache

[root@server1 memcache-2.2.5]# make             ##编译

[root@server1 memcache-2.2.5]# make install   ###安装

Installing shared extensions:     /usr/local/lnmp/php/lib/php/extensions/no-debug-non-zts-20131226/


[root@server1 memcache-2.2.5]# cd /usr/local/lnmp/php/lib/php/extensions/no-debug-non-zts-20131226/

[root@server1 no-debug-non-zts-20131226]# ls

memcache.so  opcache.a  opcache.so

[root@server1 no-debug-non-zts-20131226]# /etc/init.d/memcached restart


3.编译PHP配置文件并配置memcache的测试页

[root@server1 ~]# vim /usr/local/lnmp/php/etc/php.ini 

    863     extension=memcache.so

[root@server1 ~]# /etc/init.d/fpm restart

[root@server1 ~]# php -m |grep mem        ###查看php是否支持memcached

memcache

[root@server1 ~]# cd /mnt/memcache-2.2.5 

[root@server1 memcache-2.2.5]# cp example.php memcache.php /usr/local/lnmp/nginx/html/

[root@server1 memcache-2.2.5]# cd /usr/local/lnmp/nginx/html/

[root@server1 html]# vim example.php   ##分析信息不做修改

 22 define('ADMIN_USERNAME','memcache');    // Admin Username

 23 define('ADMIN_PASSWORD','willis');      // Admin Password   ##willis为密码


 28 $MEMCACHE_SERVERS[] = '127.0.0.1:11211'; // add more as an array

 29 #$MEMCACHE_SERVERS[] = 'mymemcache-server2:11211'; // add more as an array

[root@server1 html]# nginx -s reload


4.测试

http://172.25.6.10/example.php##访问网站并多次刷新

http://172.25.6.10/memcache.php##查看命中率
