This article mainly introduces "what is the knowledge of Linux system network service". In the daily operation, I believe that many people have doubts about the knowledge of Linux system network service. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "what is the knowledge of Linux system network service?" Next, please follow the editor to study!

Linux system network services, according to the methods they use, can be divided into three categories:

Services controlled by init

Services started by the System V startup script

III. Services managed by xinetd

Below, we will introduce these three services respectively.

Services controlled by init

Configured in / etc/inittab, the service that can set the respawn parameter starts automatically every time it is shut down.

After the inittab file has been modified, you can use # init Q to make the changes take effect.

II. Services initiated by System V

Started by the System V script in the / etc/rc.d/init.d/ directory. To control System V's services, we can use the

# / etc/rc.d/init.d/script {start | stop | restart |

You can also use the service command to execute a script, such as

# service sshd restart

The default switches for System V services can be different at different levels. We use chkconfig and ntsysv to control.

# chkconfig-- list looks at the switches at all levels of the system's system v service.

# chkconfig sshd on | off changes the default switch at sshd service level 2-5

# chkconfig-- level level sshd on | off changes the default switch of the sshd service at a certain level.

# ntsysv is a graphical interface, you can choose after you run the command, but it only affects the current level.

III. Management of xinetd services

The management files for the xinetd service are placed in the / etc/xinetd.d directory, and we can edit the service files in this directory to turn the service on and off. Every service file has the line disable. If you change the value to yes, you will disable the service. If it is no, you will start the service. After the modification is successful, you need to restart the xinetd service for the change to take effect.

# service xinetd restart
