nginx+多resin进程实现负载均衡

resin 3.1配置:

resin3.1很多配置方法都不同于3.0 , 配置上走了不少弯路.

由于前段是nginx而不是apache,srun端口用不上, nginx只能通过http端口访问resin.

而启动多resin进程只能用${resin_home}/bin/httpd.sh -server a start 这种方式来启动srun端口, 

在此把srun端口和http端口绑定起来就可以了.

resin相关配置文件如下:

<server address="127.0.0.1" port="6801">
        <http id="" port="8081"/>
    </server>
    <server id="b" address="127.0.0.1" port="6802">
        <http id="" port="8082"/>
    </server>
    <server id="c" address="127.0.0.1" port="6803">
        <http id="" port="8083"/>
    </server>
    <server id="d" address="127.0.0.1" port="6804">
        <http id="" port="8084"/>
    </server>

resin启动脚本:

#!/bin/bash
source /data/sh/profile.sh

killall -9 perl
killall -9 java
/usr/local/resin/bin/httpd.sh  -server a start
/usr/local/resin/bin/httpd.sh  -server b start
/usr/local/resin/bin/httpd.sh  -server c start
/usr/local/resin/bin/httpd.sh  -server d start

nginx的配置:

http {

 upstream resinserver {
        server 127.0.0.1:8081 weight=1;
        server 127.0.0.1:8082 weight=1;
        server 127.0.0.1:8083 weight=1;
        server 127.0.0.1:8084 weight=1;
    }

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

server_names_hash_max_size 128;
server_names_hash_bucket_size 128;
    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  15;

        limit_zone dlconn $binary_remote_addr 20m;
    #gzip  on;

    server {
        listen       80;
        server_name  tt.example.com ;
        root    /data/webapps/dw_example;
        charset utf8;

       access_log  logs/example.access.log  main;

        limit_conn dlconn 20;
        limit_rate 1m;

        location / {
#            root   html;
            index  index.html index.htm;
        }

        location ~ .*/.jsp$ {
            proxy_pass http://resinserver;
            proxy_redirect    off;
            proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_set_header  X-Real-IP  $remote_addr;
            proxy_set_header  Host $http_host;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
