What this article shares with you is about how to run Linux Anacron. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Once you have configured Linux Anacron, you can start it now. Since this is a job that must be performed on a regular basis, it is not enough to enter Linux Anacron once. There are two common ways to run Linux Anacron on a regular basis: you can start Anacron when you start your computer, or you can start the program through a Cron job. Which method to use depends on the way you use the computer on a daily basis. Generally speaking, Linux Anacron will handle system jobs, but you can also use it to handle the equivalent of user Cron jobs, so you may need to configure it to run both types of jobs at the same time.

Run Linux Anacron at startup

If you shut down and restart your computer frequently (one or more times a day), it's a good idea to run Anacron when you start your computer. After the computer starts, Anacron checks the jobs that should be run and, if necessary, runs them. In a typical business environment, for desktops, Anacron jobs are likely to be run shortly after the user starts their work. For laptops, the run cycle may be more difficult to predict (note that "boot" means full system startup; if the computer is usually placed in hibernation mode rather than shut down, the system startup script will not run, so this approach will not run Linux Anacron jobs on a regular basis).

To run Linux Anacron at startup, you must create a SysV startup script to start the software. The script to do this is simple, with the following two lines of code:

Listing 3. Run the startup script for Anacron

# / bin/bash

Anacron

You can put this script anywhere / etc/init.d, / etc/rc.d/init.d, or your distribution places its startup script. You can then create a link to the script in a directory with a standard run level, such as / etc/rc3.d or / etc/rc.d/rc3.d. You should specify a name for this link (such as S99anacron) to ensure that Anacron is started at system startup ("S" will instruct the system to run this script at startup, while "99" indicates when the system should run this script relative to other startup scripts).

If your distribution contains an Anacron package, the package may contain the appropriate SysV startup script, so you only need to check to make sure that Linux Anacron is running when you start your computer. You can find a link to the startup script whose name starts with S, or you can use tools such as chkconfig or ksysv to adjust the configuration.

After Linux Anacron is configured to run at system startup, you should observe the log files and other features managed by the Anacron job for some time. Check to make sure the Anacron job runs at the right time (note that each time Anacron runs a log file replacement job, the log file is not necessarily replaced, depending on the logrotate configuration).

The above is how to run Linux Anacron, the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
