CentOS系统使用yum方式安装Nginx服务器

Ubuntu下安装nginx，直接apt-get install nginx就行了，很方便。
但是今天装了CentOS6.3，直接yum install nginx不行，要先处理下源，下面是安装完整流程，也十分简单：

1，我的是CentOS 6，先执行：
rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
如果是CentOS 5，就用下面的源：
rpm -ivh http://nginx.org/packages/centos/5/noarch/RPMS/nginx-release-centos-5-0.el5.ngx.noarch.rpm
如果是Red Hat Enterprise Linux 6：
rpm -ivh http://nginx.org/packages/rhel/6/noarch/RPMS/nginx-release-rhel-6-0.el6.ngx.noarch.rpm
如果是Red Hat Enterprise Linux 5：
rpm -ivh http://nginx.org/packages/rhel/5/noarch/RPMS/nginx-release-rhel-5-0.el5.ngx.noarch.rpm

2，查看yum的nginx信息
[root@server ~]# yum info nginx

3，安装并启动nignx
[root@server ~]# yun install nignx
[root@server ~]# service nginx start
Starting nginx:                          [  OK  ]

4，然后进入浏览器，输入http://192.168.0.161/测试，如果看到
