In order to allow your spring boot project to be directly accessed by the domain name instead of the IP: port number, you need to use a reverse proxy.Access with domain name.Many tutorials on the Internet are for nignx, and I use apache, and I don’t want to change apache to nignx.

1. Enable Apache's proxy module

After making sure Apache is installed, enable Apache's proxy module via a2enmod proxy proxy_balancer proxy_http.

I am using Ubuntu's Apache and the Apache directory structure under centos seems to be a bit different.

2. Modify the configuration file

Switch to the /etc/apache2/sites-enabled directory and open the configuration corresponding to the website that needs to be modified

If not, create a new configuration file. The name of the file is the prefix .conf of the second-level domain name. For example, my domain name is steventan.top.

Then the website corresponding to test.conf is test.steventan.top, which seems to be just a naming habit, and it is not a big problem if it is different. This is mainly for the convenience of management.

ServerName autoclock.steventan.top #Fill in the IP or domain name of the proxy server hereProxyRequests off #off means turn on reverse proxy on means turn on forward proxyProxyPass / http://localhost:8080/ #The proxy website, the one in the middle / must not be missing, if there is less, restart and report an errorProxyPassReverse / http://localhost:8080/ #ProxyPassReverse# RewriteEngine on# RewriteCond %{HTTPS} !=on# RewriteRule ^(.*) https://%{SERVER_NAME}$1 [L,R]ErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined

The above configuration is to map the program running on the local port 8080 to the domain name autoclock.steventan.top, which achieves my purpose. The spring boot project running on the server can be accessed directly on the public network through the domain name.

3. Restart apache to take effect configuration

Restart Apache via service apache2 restart to make the configuration file take effect.
