nginx+memcache，nginx


一、Openresty

1、编译、安装opesresty

[root@server6 ~]# tar zxf openresty-1.13.6.1.tar.gz 
[root@server6 ~]# cd openresty-1.13.6.1
[root@server6 openresty-1.13.6.1]# ./configure --prefix=/usr/local/lnmp/openresty
[root@server6 openresty-1.13.6.1]# gmake && gmake install

2、配置文件

[root@server6 ~]# vim /usr/local/lnmp/openresty/nginx/conf/nginx.conf




3、打开 memcached、php-fpm、nginx

[root@server6 ~]# /etc/init.d/memcached start
Starting memcached:                                        [  OK  ]
[root@server6 ~]# /etc/init.d/php-fpm start
Starting php-fpm  done
[root@server6 ~]# /usr/local/lnmp/openresty/nginx/sbin/nginx 
[root@server6 ~]#

4、物理主机测试
Nginx 没有添加 Memcache 模块，Php有 Memcache 模块

Nginx 添加 Memcahche 模块，Php 相当于 “双 Memcache”

相比较而言，Nginx 添加 Memcache 模块后，速度由441提高至2408，性能得到显著优化！而 Php 性能也得到了一定的优化！
