Tomcat is used to publish JSP web pages. According to the actual needs of the enterprise, N Tomcat instances will be configured on a single server. At the same time, the instances created by Tomcat will be manually added to the Nginx virtual host. At the same time, restart Nginx, develop Nginx, Tomcat to automatically create Tomcat Examples and Nginx virtual machine management scripts can greatly reduce manual intervention and achieve rapid delivery.
This shell script implements automatic installation of Nginx, virtual host, and automatic addition of Tomcat to the virtual machine.
1. Manually copy the directory where Tomcat is consistent with the script (can be modified by yourself);
2. Manually modify the Tomcat port to 6001, 7001, 8001 (can be modified by yourself);
3. The script specifies the parameter as v1.example.com;
4. Create a v1.example.com Tomcat instance;
5. Modify the Tomcat instance port to ensure that the port is unique;
6. Add the Tomcat instance to the Nginx virtual machine;
7. Repeat the creation of Tomcat instance, the port is automatically increased, and the original Nginx virtual host is added to achieve load balancing;
The specific implementation script is as follows:
#!/bin/bash
#Auto config Nginx and tomcat cluster
#By author falnet
#Define Path variables
