ecshop redis配置

此文被围观2909 日期: 2017-09-13 分类 : 服务器  标签:  ·····

前面从朋友手里接到一个任务,就是维护由ecshop二次的微网站,服务器系统ubuntu(阿里云4核8G,20M带宽)

服务器web环境,nginx+php5.5.38+mysql

这网站访问量应该说还是有点大的,我接触到的网站来比较的,目前数据大概在500多万的数据

有几个表的数据量比较大:订单表,用户表,订单日志表,还有一个session表


如何在ecshop上添加redis支持:

 cls_redis_session.php


/*------------------------------------------------------ */
//-- 该类用于将SESSION直接写入Memcache
/*------------------------------------------------------ */
class cls_redis_session

在init.php里面修改:

/* 添加redis支持 */
	if (isset($session_type) && $session_type == "redis")
	{
		include(ROOT_PATH . 'include/cls_redis_session.php');
		$sess = new cls_redis_session($db, $ecs->table('sessions'), $ecs->table('sessions_data'), 'ECSCP_ID');
	}else{ 
		include(ROOT_PATH . 'include/cls_session.php');
		$sess = new cls_session($db, $ecs->table('sessions'), $ecs->table('sessions_data'));
	}


在config里面添加:

//使用redis 2017/9/12
$session_type = "redis";



php添加redis扩展:

http://www.cnblogs.com/zgaspnet/p/3939198.html 

phpredis我是下载的2.2.8


添加redis服务端:

1、下载软件包

https://redis.io/download

2、解压安装

#tar –xzvf redis-4.0.1.tar.gz

#cd redis-4.0.1/

#make #这里如果没有安装make编译的话,需要安装apt-get update && apt-get install make

#cd src

#make install PREFIX=/usr/local/redis #注意这里大小写

#cd ..

#mkdir /usr/local/redis/etc/

#cp redis.conf /usr/local/redis/etc/   #复制配置文件

3、启动服务

#cd /usr/local/redis

#./bin/redis-server ./etc/redis.conf   #启动服务

#vim ./etc/redis.conf   #daemonize值改为yes redis就在后台运行

#./bin/redis-cli   #客户端链接

#./bin/redis-cli shutdown    #停止实例

#vim /etc/rc.local 

加入开机启动/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
