mysql部分

groupadd -r mysql

useradd -r -g mysql -s /bin/false -M mysql
 
tar zxf mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz

memcache部分

tar zxf libevent-2.0.22-stable.tar.gz

cd libevent-2.0.22-stable/

./configure && make&& make install

tar zxf memcached-1.4.33.tar.gz

cd memcached-1.4.33/

./configure --prefix=/usr/local/memcached --with-libevent=/usr/local

make && make install

vi ~/.bash_profile

MEMCACHED_HOME=/usr/local/memcached
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$MEMCACHED_HOME/lib

memcached -d -m 2048 -l 192.168.154.131 -p 11211 -u root -c 10240 -P /usr/local/memcached/memcached.pid

firewall-cmd --permanent --add-port=11211/tcp

firewall-cmd --reload

在php上

加载memcache.so（使php作为memcache的客户端）

tar zxf memcache-3.0.8.tgz

cd memcache-3.0.8/

/usr/local/php/bin/phpize

./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config

make && make install

注意：安装完后会有类似这样的提示： Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20131226/；记住这个路径，需要加载到php的配置文件中。

vim /etc/php.ini

##查找extension并在对应位置添加
extension=/usr/local/php/lib/php/extensions/no-debug-zts-20131226/memcache.so
##在末尾添加
session.save_handler = memcache
session.save_path = "tcp://192.168.154.131:11211?persistent=1&weight=1&timeout=1&retry_interval=15"

service php-fpm restart

在nginx上

编写php测试页面。vim /usr/local/nginx/html/index.php

<?php
phpinfo();
?>

访问，应当可以看到memcache和session字样。

（成功表示php上安装好了memcache.so）

编写memcache测试页面。vim /usr/local/nginx/html/test.php
