Nginx deploys front-end and back-end separation services and configuration instructions

This article mainly introduces the front-end and back-end separation services and configuration instructions for Nginx deployment. It has certain reference value. Now I share it with you. Friends in need can refer to it

Install Nginx

Use the yum command to install Nginx in CentOS 7 server:

sudo yum install -y nginx

Configure Nginx

File location

Generally, the nginx configuration file is in the etc directory. You can also execute the command rpm -ql nginx to view the path.

After switching to the /etc/nginx directory, you can see the nginx.conf configuration file.
Execute vi nginx.conf to open the configuration file.

vim common commands

Deployment of front-end and back-end separation projects

In the front-end and back-end separation project, the front-end The code will be packaged into pure static files. The purpose of using Nginx is to allow static files to run services. Since the back-end interface is also separated, direct requests may cause cross-domain problems. In this case, Nginx is required to forward the proxy back-end interface.

Nginx configuration is as follows

}

• Put the

  dist file packaged with the front-end code into the specified service directory

• Specify the service directory to the

  spa-project/dist directory to proxy the static service

• Gzip compression is enabled in the configuration , can greatly reduce the file size

• Redirect the 404 error page to index.html, which can solve the problem of 404 in the front-end history routing mode due to the inability to access the service when refreshing the page. The problem

• location is the proxy interface. You can forward the request interface domain name or IP of the proxy backend to solve the interface cross-domain problem

Start Nginx service

After completing the configuration, you can start nginx

Execute
nginx -t to test whether the Nginx configuration is correct. Execute
nginx, and the nginx service can be started if the configuration file is correct. After modifying the nginx configuration file, execute
nginx -s reload to complete the smooth transition and reload the configuration
