1.1. 安装

参考 http://nginx.org/en/linux_packages.html

下载 key
sudo rpm --import nginx_signing.key

1.1.2. 更新源

To set up the yum repository for RHEL/CentOS, create the file named /etc/yum.repos.d/nginx.repo with the following contents:

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

Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.

server {
  listen       81;
  server_name  *.efg.com;
  location / {
    proxy_pass http://localhost:8080;
    proxy_set_header   Host    $host;
    proxy_set_header   X-Real-IP   $remote_addr;
