[Nginx] Nginx同一个域名配置多个项目的实现方法

• nginx按不同的目录分发给不同的项目
  
• 启用二级域名，不同的项目分配不同的二级域名
  

server {
  listen  80;
  server_name example.com;
 
  location ^~ /project1 {
  proxy_pass   http://localhost:8081;
  proxy_set_header Host  $host;
  proxy_set_header X-Real-IP  $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
 
  location ^~ /project2 {
  proxy_pass   http://localhost:8082;
  proxy_set_header Host  $host;
  proxy_set_header X-Real-IP  $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
 
  location / {
  proxy_pass   http://localhost:8080;
  proxy_set_header Host  $host;
  proxy_set_header X-Real-IP  $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

• http://example.com/project1路径分发到http://localhost:8081
  
• http://example.com/project2路径分发到http://localhost:8082
  
• 其他路径分发到http://localhost:8080
  

server {
  listen  80;
  server_name example.com;
  location / {
  proxy_pass   http://localhost:8080;
  proxy_set_header Host  $host;
  proxy_set_header X-Real-IP  $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

server {
  listen  80;
  server_name project1.example.com;
  location / {
  proxy_pass   http://localhost:8081;
  proxy_set_header Host  $host;
  proxy_set_header X-Real-IP  $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

server {
  listen  80;
  server_name project2.example.com;
  location / {
  proxy_pass   http://localhost:8082;
  proxy_set_header Host  $host;
  proxy_set_header X-Real-IP  $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}
