nginx负载算法 memcache实现会话保存

[root@Z-LB nginx]# cat conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
#加入upstream模块
    upstream bbs_server_pools{
        #ip_hash; 默认是轮循算法
        server 192.168.14.131:80;
        server 192.168.14.134:80;
    }

    include extra/bbs.conf;
    }

[root@Z-LB nginx]# cat conf/extra/bbs.conf 
server {
    listen       80;
    server_name  bbs.lanny.com;
    
    location / {
            proxy_pass http://bbs_server_pools;
            proxy_set_header Host        $host;
            proxy_set_header X-Forwarded-For $remote_addr;
            }
