STEP1.安装必备的gem包

 
 geminstall–include-dependenciesmongrel
geminstall–include-dependenciesmongrel_cluster

STEP2.配置

Mongre_cluster的设置比较简单，进入Rails应用的根目录，执行

 
 cd/var/www/demo
 mongrel_railscluster::configure-eproduction-p8000-a127.0.0.1-N5-c/var/www/demo

其中

-e 指定运行环境，有production(生产)、development(开发)、test(测试)三个选项。
-p 指定监听端口
-a 127.0.0.1 指定Mongrel在localhost下监听
-N5 启动两个Mongrel进程，端口从8000~8004

执行以上命令后，会在/var/www/demo/config目录产生mongrel_cluster.yml文件

 
 ---
cwd:/var/www/demo
log_file:log/mongrel.log
 port:"8000" 
environment:production
address:127.0.0.1
pid_file:tmp/pids/mongrel.pid
servers:5
 

至于mongrel_railscluster::configure命令的详细用法，可以mongrel_railscluster::configure --help查看
