In fact, its script supports multiple ports, but the configuration in the template is not supported by default. The script parameters are as follows: Usage: phpss_get_mysql_stats To monitor the performance of mysql server, it is estimated that

So you need to open the necessary ports on the firewall to allow traffi

Environment: Tomcat7.0.55Tomcat to build multiple sites with different IP ports Tomcat is used in the development environment, but sometimes also in production environments. In a production environment, you will encounter multiple sites that need to be placed under one tomcat. Sometimes it is also necessary to open multiple different ports at the same time to accept multiple domain name requests. Typic
