How To Stop Apache2 from Auto-Starting on Boot

Ubuntu 18

In this article, we will guide you through the process of disabling Apache2 from automatically starting when your system boots. This can be particularly useful if you’re running a local development environment and don’t want Apache2 running all the time, or if you’re looking to optimize your server’s resources.

Quick Answer

To stop Apache2 from auto-starting on boot, you can use either the update-rc.d command or the systemctl command. With update-rc.d, you can disable Apache2 auto-start by running sudo update-rc.d apache2 disable, and enable it again with sudo update-rc.d apache2 enable. With systemctl, you can disable Apache2 auto-start with sudo systemctl disable apache2, and enable it again with sudo systemctl enable apache2.

Understanding Apache2

Apache2 is one of the most popular open-source web servers. It’s often used in combination with MySQL and PHP to run dynamic websites. However, once installed, Apache2 will automatically start every time your system boots. This can be unnecessary, especially if you’re not always using the Apache2 server.

Disabling Apache2 Auto-Start Using update-rc.d

One of the ways to disable Apache2 from starting automatically is by using the update-rc.d command. This command is used to install, remove, enable, or disable system services in Ubuntu.

Here’s how to use it:

  1. Open your terminal.
  2. Type the following command:
sudo update-rc.d apache2 disable

The sudo command is used to execute the following command with administrative privileges. update-rc.d is the command to update the System V style init script links. apache2 is the service we want to disable, and disable is the action we want to perform.

This command will remove the symbolic links in the runlevel directories that start Apache2 at boot.

If you later decide to enable Apache2 auto-start, you can do so by running:

sudo update-rc.d apache2 enable

The enable action will recreate the symbolic links.

Disabling Apache2 Auto-Start Using systemctl

If you are using a Linux distribution with systemd, such as Ubuntu 15.04 and newer, you can use the systemctl command to prevent Apache2 from starting at boot.

Here’s how to do it:

  1. Open your terminal.
  2. Type the following command:
sudo systemctl disable apache2

The sudo command is used to execute the following command with administrative privileges. systemctl is the command to control the systemd system and service manager. disable is the action we want to perform, and apache2 is the service we want to disable.

This command will disable the automatic startup of Apache2 while still allowing you to manually start and stop the service.

To enable Apache2 auto-start again, you can run:

sudo systemctl enable apache2

The enable action will recreate the symbolic links.

Conclusion

In this article, we have covered how to stop Apache2 from automatically starting when your system boots. We’ve gone through two methods using update-rc.d and systemctl commands. Remember to replace disable with enable in the commands if you want to revert the changes. Always ensure you have the necessary administrative privileges to execute these commands.

Can I disable Apache2 auto-start on any Linux distribution?

Yes, you can disable Apache2 auto-start on any Linux distribution. The methods mentioned in this article, using update-rc.d and systemctl, are applicable to most Linux distributions.

Will disabling Apache2 auto-start affect my server’s performance?

Disabling Apache2 auto-start will not directly affect your server’s performance. It will simply prevent Apache2 from starting automatically when your system boots. This can be useful if you want to optimize your server’s resources or if you’re running a local development environment.

Can I manually start and stop Apache2 after disabling auto-start?

Yes, you can manually start and stop Apache2 even after disabling auto-start. Disabling auto-start simply prevents Apache2 from starting automatically when your system boots. You can still manually start and stop the Apache2 service using the appropriate commands for your Linux distribution.

How can I check the current status of Apache2?

You can check the current status of Apache2 by using the following command:

sudo systemctl status apache2

This command will display the current status of the Apache2 service, including whether it is running or stopped.

Can I enable Apache2 auto-start again after disabling it?

Yes, you can enable Apache2 auto-start again after disabling it. Both the update-rc.d and systemctl commands provide an enable action that can be used to recreate the necessary symbolic links and enable Apache2 auto-start.
