nginx

安装Nginx

http://nginx.org/en/linux_packages.html#RHEL-CentOS

配置Nginx

nginx.conf 文件可能在以下目录：/usr/local/nginx/conf, /etc/nginx, or /usr/local/etc/nginx

 配置域名代理，可以在conf.d目录中添加

 分别配置

# saas.conf
server {
    listen 80;
    server_name  saas-export-manager.xxx.net;
    location / {
       proxy_pass http://127.0.0.1:8080;
    }
}
# saas-manager.conf
server {
    listen 80;
    server_name  saas-export.xxx.net;
    location / {
       proxy_pass http://127.0.0.1:8081;
    }
}

配置反向代理

server{
    listen    8001;
    server_name    10.202.203.29;
    location /
    {
        proxy_pass    http://10.200.80.21;
    }
}
server{
    listen    8002;
    server_name    localhost;
    location /
    {proxy_pass    http://10.200.151.28;}
}

访问http://10.202.203.29:8001  打开10.200.80.21

访问http://10.202.203.29:8002  打开10.200.151.28

还可以配置有端口的

server {
    listen 80;
    location / {
        proxy_pass http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $http_host;
        proxy_cache_bypass $http_upgrade;
    }
}

这样的话80端口的访问都会转发到5000端口

负载均衡

server{
    listen    8001;
    server_name    10.202.203.29;
    location /
    {
        proxy_pass    http://backend;
    }
}
upstream backend
{
    server    10.200.151.28;
    server    10.200.80.21;
}
