【Nginx】均衡负载权重模式实现session数据同步-LMLPHP

思路:把session存放到一个公共redis服务器上

每次浏览器请求服务端都会带上cookie,因为使用的是权重负载均衡方案,因此nginx反向代理服务器会把请求发放到不同的服务端,服务端用cookie,可以去公共redis服务器取session值

server1:

<?php
ini_set("session.save_handler", "redis");
ini_set("session.save_path", "tcp://192.168.174.132:6379");
session_start(); echo "server1"; if(isset($_SESSION['uid']))
{
echo $_SESSION['uid'];
}else{
echo "no";
$_SESSION['uid'] = 1;
}

server2:

<?php
ini_set("session.save_handler", "redis");
ini_set("session.save_path", "tcp://192.168.174.132:6379");
session_start(); echo "server2"; if(isset($_SESSION['uid']))
{
echo $_SESSION['uid'];
}else{
echo "no";
$_SESSION['uid'] = 1;
}
