Apache+php+memcache集群搭建
实验环境：RHEL7.0server1.example.com172.25.254.1server2.example.com172.25.254.2
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）
# yum install memcached -y
# /etc/init.d/httpd start
# /etc/init.d/memcached start
# curl -I localhost
HTTP/1.1 200 OK

2.编译安装memcache使其支持php
# php -m |grep memcache ###可以看到php不支持memcached
# cd /mnt/
# ls
memcache-2.2.5.tgz
# tar -zxf memcache-2.2.5.tgz ###解压tar zxfmemcache-2.2.5.tgz
# cd memcache-2.2.5 ###进入解压目录
# ls
# phpize ##会自动生成configure
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
# yum install libtool -y
# ./configure \
> --prefix=/usr/local/lnmp/php/modules \
> --enable-memcache
# make ##编译
# make install ###安装
Installing shared extensions: /usr/local/lnmp/php/lib/php/extensions/no-debug-non-zts-20131226/
# cd /usr/local/lnmp/php/lib/php/extensions/no-debug-non-zts-20131226/
# ls
memcache.soopcache.aopcache.so
# /etc/init.d/memcached restart
3.编译PHP配置文件并配置memcache的测试页
# vim /usr/local/lnmp/php/etc/php.ini
863 extension=memcache.so
# /etc/init.d/fpm restart
# php -m |grep mem ###查看php是否支持memcached
memcache
# cd /mnt/memcache-2.2.5
# cp example.php memcache.php /usr/local/lnmp/nginx/html/
# cd /usr/local/lnmp/nginx/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
# nginx -s reload
4.测试
