安装和配置Apache + mongrel cluster

背景：

机器1 192.168.100.231, os: CentOS release3.6 (Final),装上apache2.3.6+mongrel cluster

机器2 192.168.100.234, os: CentOS release4.3 (Final) 装上 mongrel cluster

1）安装和配置mongrel_cluster

geminstallmongrel_cluster


cd#{your_rails_app_root}

mongrel_railscluster::configure-eproduction-p4000-N4-c#{your_rails_app_root}-a127.0.0.1

上面命令在#{your_rails_app_root}/config产生如下配置文件mongrel_cluster.yml

内容如下：

cwd:#...{your_rails_app_root}
log_file:log/mongrel.log
port:"4000"
environment:production
address:127.0.0.1
pid_file:tmp/pids/mongrel.pid
servers:4

上面已经安装和配置好mongrel_cluster，开始启动和停止试试

启动：

mongrel_railscluster::start

结果：

startingport4000
startingport4001
startingport4002
startingport4003

停止

mongrel_railscluster::stop

结果：

stoppingport4000
stoppingport4001
stoppingport4002
stoppingport4003

注意

上面的 配置过程并没有为mongrel_cluster产生特别的用户和组，如果你已非root身份登陆可能是需要的

2)安装apache2.2.6

cd/usr/local

wgethttp://apache.mirror.phpchina.com/httpd/httpd-2.2.6.tar.gz

tarxvzfhttpd-2.2.6.tar.gz

cdhttpd-2.2.6

./configure--prefix=/usr/local/apache2.2.6
--enable-proxy=shared
--enable-proxy_http=shared
--enable-proxy-balancer=shared

make&&makeinstall

由于apache2.2.6的配置文件中已经引入了

LoadModuleproxy_modulemodules/mod_proxy.so
LoadModuleproxy_http_modulemodules/mod_proxy_http.so
LoadModuleproxy_balancer_modulemodules/mod_proxy_balancer.so

所以你无需在配置文件加入这些

你的加上如下部分

<Proxybalancer://spacecluster>
#clustermembers
BalancerMemberhttp://127.0.0.1:4000
BalancerMemberhttp://127.0.0.1:4001
BalancerMemberhttp://127.0.0.1:4002
BalancerMemberhttp://127.0.0.1:4003

BalancerMemberhttp://192.168.100.234:4000
BalancerMemberhttp://192.168.100.234:4001
BalancerMemberhttp://192.168.100.234:4002
BalancerMemberhttp://192.168.100.234:4003
</Proxy>

ExtendedStatusOn
<Location/server-status>
SetHandlerserver-status
</Location>

<Location/balancer-manager>
SetHandlerbalancer-manager
</Location>

<VirtualHost*:80>
ServerNamespace.mofile.com

ProxyRequestsOff

ProxyPass/balancer-manager!
ProxyPass/server-status!
ProxyPass/balancer://spacecluster/
ProxyPassReverse/balancer://spacecluster/
</VirtualHost>

到此你的 apache+mongrel cluster就安装配置好了，你可以用浏览器访问apache看看是否生效了
