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:

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;
    }

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

    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;

        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
        #

        location = /50x.html {
            root   html;
        }
    }
