memcached高缓存搭建

memcached高缓存搭建

memcached高缓存搭建搭建服务端和客户端，让服务端去链接客户端web客户端：192.168.247.161服务端：192.168.247.160

[root@localhost ~]# hostnamectl set-hostname client [root@localhost ~]# su [root@client ~]#

[root@nginx ~]# hostnamectl set-hostname server [root@nginx ~]# su [root@server ~]#

搭建服务端部署libevent 事件通知库

[root@server ~]# mkdir /abc mkdir: cannot create directory ‘/abc’: File exists [root@server ~]# mount.cifs //192.168.254.10/linuxs /abc Password for root@//192.168.254.10/linuxs: [root@server ~]# cd /abc [root@server abc]# tar zxvf libevent-2.1.8-stable.tar.gz -C /opt [root@server abc]# tar zxvf memcached-1.5.6.tar.gz -C /opt [root@server abc]# cd /opt [root@server opt]# ls data libevent-2.1.8-stable memcached-1.5.6 nginx-1.12.2 rh [root@server opt]# cd libevent-2.1.8-stable/ [root@server libevent-2.1.8-stable]# yum install gcc gcc-c++ make -y [root@server libevent-2.1.8-stable]# ./configure --prefix=/usr/local/libevent [root@server libevent-2.1.8-stable]# make && make install

libevent安装完毕，接下来安装memcached

[root@server libevent-2.1.8-stable]# cd /opt/memcached-1.5.6/ [root@server memcached-1.5.6]# ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent [root@server memcached-1.5.6]# make && make install [root@server memcached-1.5.6]# ln -s /usr/local/memcached/bin/* /usr/local/bin/

[root@server memcached-1.5.6]# 下一步安装客户端，安装客户端首先要部署LAMP架构环境，LAMP架构部署详细过程可查看博客：abc]# yum install autoconf -y [root@client htdocs]# cd /abc [root@client abc]# tar zxvf memcache-2.2.7.tgz -C /opt [root@client abc]# cd /opt [root@client opt]# ls memcache-2.2.7 mysql-5.6.26 package.xml php-5.6.11 rh [root@client opt]# cd memcache-2.2.7/ [root@client memcache-2.2.7]# ls config9.m4 example.php memcache.php memcache_standard_hash.c config.m4 memcache.c memcache_queue.c php_memcache.h config.w32 memcache_consistent_hash.c memcache_queue.h README CREDITS memcache.dsp memcache_session.c [root@client memcache-2.2.7]#

在web客户端去检测服务端是否可以连接

[root@client memcache-2.2.7]# cd /usr/local/httpd/htdocs/ [root@client htdocs]# ls index.php [root@client htdocs]# vim gsy.php connect('192.168.247.160',11211); $memcache->set('key','Memcache test Successfull',0,60); $result = $memcache->get('key'); unset($memcache); echo $result; ?> [root@client htdocs]# service restart
