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;
