The biggest feature of the Nginx Web server is that Nginx is often used for load balancing and reverse proxy. A single Nginx server is configured with multiple virtual hosts, and a hundred servers are configured with multiple virtual hosts. Based on Shell scripts, virtual hosts can be more efficiently configured and added ,management. This knowledge point mainly introduces the use of Shell scripts to implement automatic Nginx installation and maintenance of virtual hosts. The writing ideas are as follows:
- Determine whether the Nginx WEB software service is deployed or running;
- Support the addition of a single virtual host;
- Support adding multiple virtual hosts;
- Support deleting a single virtual host or multiple virtual hosts
