This paper introduces the method of Nginx+Tomcat multi-site deployment and shares it with you as follows:

Tomcat configuration:

Add multiple domain names:

Under the Engine node:

Add domain name 1 


<Host name="test1.java.com" appBase="webapps1"
    unpackWARs="true" autoDeploy="true">
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
      prefix="localhost_access_log" suffix=".txt"
      pattern="%h %l %u %t "%r" %s %b" />
 <Context path="" docBase="/var/lib/tomcat8/webapps/test1" debug="0" reloadable="true" crossContext="true" />
 </Host>

Add domain name 2 


<Host name="test1.java.com" appBase="webapps2"
    unpackWARs="true" autoDeploy="true">
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
      prefix="localhost_access_log" suffix=".txt"
      pattern="%h %l %u %t "%r" %s %b" />
  <Context path="" docBase="/var/lib/tomcat8/webapps/manage" debug="0" reloadable="true" crossContext="true" />
 </Host>

Note that you also need one default statement, the domain name name="localhost", otherwise tomcat will occasionally report a null pointer error and become unusable 


 <Host name="localhost" appBase="webapps0"
    unpackWARs="true" autoDeploy="true">
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
      prefix="localhost_access_log" suffix=".txt"
      pattern="%h %l %u %t "%r" %s %b" />
  <Context path="" docBase="/var/lib/tomcat8/webapps/manage" debug="0" reloadable="true" crossContext="true" />
 </Host>

At this point, the configuration is complete and tomcat is restarted: 


sudo /etc/init.d/tomcat8 stop
sudo /etc/init.d/tomcat8 start

or 


sudo /etc/init.d/tomcat8 restart

Once the domain name resolution is complete, you can test it in your browser

http://test1.java.com:8080
http://test2.java.com:8080

If correct, it can be accessed normally

Configuration Nginx

Enter the Nginx root directory (ubuntu 16.04 shall prevail) 


cd /etc/nginx

Enter the sites-available directory 


cd sites-available

Create a configuration file (test1.java.com for example) 


vi test1.java.com

Enter configuration content 


server{
    listen 80;
    server_name test1.java.com;
    server_name_in_redirect off;
    proxy_set_header Host $host:$server_port;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header REMOTE-HOST $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    location / {
        proxy_pass http://test1.java.com:8080;
    }
}

After esc :wq is saved

Creating a soft connection has been used 


ln -s /etc/nginx/sites-available/test1.java.com /etc/nginx/sites-enabled/test1.java.com

Restart Nginx 


<Host name="test1.java.com" appBase="webapps2"
    unpackWARs="true" autoDeploy="true">
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
      prefix="localhost_access_log" suffix=".txt"
      pattern="%h %l %u %t "%r" %s %b" />
  <Context path="" docBase="/var/lib/tomcat8/webapps/manage" debug="0" reloadable="true" crossContext="true" />
 </Host>
0

Configuration is now complete

There are also some other configuration methods, such as tomcat, which can be configured for multiple ports and multiple sites. However, I found that the speed was obviously slowed down after configuration, and I did not find the reason. However, this configuration has already met the requirements.
