nginx+tomcat+memcached负载均衡session

我使用的版本

tomcat-7.0.42
nginx-1.9.2
memcached-win32-1.4.4-14

安装方法这里就不再说明一大堆

注意：这里需要注意的是tomcat里需要memcached jar包
链接：http://pan.baidu.com/s/1pLRICUB
密码：u72i
下载完把jar直接放到tomcat的lib文件下

第一步tomcat配置

⑴ conf/context.xml中在<Context></Context> 节点中加入以下配置每个tomcat1，tomcat2各配置一个

<Manager  
className="de.javakaffee.web.msm.MemcachedBackupSessionManager"  
memcachedNodes="n1:localhost:11211"  
sticky="false"  
sessionBackupAsync="false"  
lockingMode="uriPattern:/path1|/path2"  
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"  
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"/>

⑵ conf/server.xml 加入 jvmRoute=”tomcat7-1”
依次类推tomcat2，jvmRoute=”tomcat7-2”
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat7-1">

第二步nginx配置

这是我的nginx配置，在upstream 里配置了俩个服务

#user  nobody;
worker_processes  auto;
worker_rlimit_nofile 100000; 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections 204800; 
    multi_accept on; 


}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  10;

    #gzip  on;


    server_names_hash_max_size 512;
    server_names_hash_bucket_size 128;


upstream localhost {
    server 192.168.23.24:8080 weight=1 fail_timeout=5s;
    server 192.168.23.24:8012 weight=5 fail_timeout=5s;
}




server {

        listen       80;

        server_name  192.168.23.24; 

            location / { 
                  root   html; 
                  index  index.html index.htm; 
                  proxy_pass   http://localhost;
                  proxy_redirect    off; 
                  proxy_set_header   Host $host; 
                  proxy_set_header   X-Real-IP $remote_addr; 
                  proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;  
                  client_max_body_size   10m; 
                  client_body_buffer_size   128k; 
                  proxy_connect_timeout 10;
                  proxy_send_timeout   90; 
                  proxy_read_timeout   90; 
                  proxy_buffer_size   4k; 
                  proxy_buffers   4 32k; 
                  proxy_busy_buffers_size   64k; 
                  proxy_temp_file_write_size  64k;         
              }
       }

     }
