nginx配置

Web开发

centos 6.5配置

  • /etc/yum.repos.d/目录下创建一个源配置文件nginx.repo：

    cd /etc/yum.repos.d/

    vim nginx.repo

    填写如下内容：

    [nginx]
    name=nginx repo
    baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
    gpgcheck=0
    enabled=1

    保存，则会产生一个/etc/yum.repos.d/nginx.repo文件。

  • 直接执行如下指令即可自动安装好Nginx：

    yum install nginx -y
    安装完成，下面直接就可以启动Nginx了：

    /etc/init.d/nginx start

    现在Nginx已经启动了，直接访问服务器就能看到Nginx欢迎页面了的。

  • 如果还无法访问，则需配置一下Linux防火墙。

    iptables -I INPUT 5 -i eth0 -p tcp –dport 80 -m state –state NEW,ESTABLISHED -j ACCEPT

    service iptables save

    service iptables restart
    Nginx的命令以及配置文件位置：

    /etc/init.d/nginx start # 启动Nginx服务

    /etc/init.d/nginx stop # 停止Nginx服务

    /etc/nginx/nginx.conf # Nginx配置文件位置

    chkconfig nginx on #设为开机启动

    至此，Nginx已经全部配置安装完成。

一台主机上适应多个服务器：
在你的nginx通过代理的方式转发请求：配置如下
vi /etc/nginx/nginx.conf
在http加入下面的内容，参考：http://wiki.nginx.org/FullExample
http {
....
  server {
          listen       80;
          server_name  www.a.com;
          charset utf-8;
          access_log  /home/a.com.access.log  main;
          location / {
              proxy_pass http://127.0.0.1:80;
          }
      }
  
   server {
          listen       80;
          server_name  www.b.com;
          charset utf-8;
          access_log  /home/b.com.access.log  main;
          location / {
              proxy_pass http://127.0.0.1:81;
          }
      }
