Nginx reverse proxy demo

Regarding the basic understanding of Nginx, Taobao’s documentation has introduced it very clearly: http://tengine.taobao.org/book/
The following records some specific usage processes. Easy to check in the future.

1. Overall configuration steps:

1. Install Nginx.
   1. Install dependency packages, including pcre and zlib dependencies. Search the yum list under the root authority of centos7 and then install it.
   2. Download Nginx. ./configure ---> make ---> make install. (If the installation is successful, you will know where it is installed by looking at the prompts, usually in /usr/local/nginx)
   3. Visit wget 127.0.0.1 to see the installation success.
2. Prepare a machine to put the Web application. For example, my application address is 192.168.1.99.157:8081/springmvc. Prepare another machine (the IP of the machine where I installed Nginx is 192.168.199.176) and install the above Nginx (in fact, you can also test it with the same machine, using different ports as different machines)
3. After installing Nginx Modify the nginx.conf main configuration file on the machine. For example, the following configuration file (beta version):

   1.  

      worker_processes 2;

       

      events {

      worker_connections 1024;

      }

      '$status $body_bytes_sent "$http_referer" '

      '"$http_user_agent" "$http_x_forwarded_for"';

       

      upstream apm {

      server 192.168.199.157:8081;

      }

      server {

      listen 8080;

      server_name 192.168.199.176;

      charset utf-8;

      location /springmvc/ {

      proxy_pass http://apm;

      }

      }

       

      sendfile on;

      keepalive_timeout 65;

      }

4. When accessing 192.168.199.176:8080/springmvc/, the homepage of 192.168.199.157:8081/springmvc was successfully accessed
