When running Apache, which is widely used as a web server, Apache may need to be restarted after configuration changes or module additions/updates. This section describes the basic commands for restarting Apache.
In general, Apache can be restarted in the following two ways: 1.
sudo service httpd restartsudo /etc/init.d/httpd restart
The first method restarts Apache (httpd) using the service command. Many modern Linux distributions recommend this method.
The second method, on the other hand, calls the initialization script directly, and is the method used on older systems and certain distributions. However, modern systems have systemd installed, and the service command is commonly used.
Both methods restart Apache precisely, so choose the appropriate command depending on the distribution and system conditions you are using.
It is also recommended to check the Apache log files in case of errors during the restart or to verify that configuration changes have been correctly applied.
