Export CATALINA_HOME =/opt/app/tomcat-8090

4. start tomcat

5. configure server load balancer in Nginx:

Nginx configuration file, add:

Upstream tomcatCluster {

Server : 8080;

Server : 8090;

}

Server

{

Listen 80;

Server_name <Domain name> ......;

Index ......;

Root ......;

Location /{

Location ~ */ <Project name> /{

Proxy_pass http: // tomcatCluster;

}

}

}

Restart Nginx: service nginx restart

6. test whether requests are forwarded to two tomcat servers in turn.
