Uredhat provides chkconfig this command to manage system service on/off at different operating levels: Chkconfig ServiceName on/off and can view current development status with Chkconfig--list (two bars).
Without this command in Ubuntu, you can actually manage the system service without any commands, and you can manage the service by changing the startup script name under/ETC/RC*.D (* for values from 0 to 6 and s). For example, do not want to let KDM automatically start, you can: sudo find/etc/rc*-name *kdm*-exec rm {}/; That is, the KDM startup script is all erased.
Ubuntu also provides another simple command for managing. But first the service must already exist in the/ETC/INIT.D directory. Such as:
Add a service: sudo update-rc.d ServiceName defaults
Remove a service: sudo update-rc.d ServiceName remove
You can also install a more powerful tool: sudo apt-get install sysv-rc-conf sysvconfig
Start: sudo sysv-rc-conf It configures the startup situation of each service at all levels.
Whenever you want to start a service, you can: Sudo/etc/init.d/servicename start
For example I want to telnet, to use SSH service: SUDO/ETCINIT.D/SSH Start (other system may be sshd)
You can also do something else: start: Start the service stop: Stop service restart: Shut down the service, and then restart Reload: Do not restart the configuration file status: Provides the current state of the service Condrestart: If the service is locked, This to shut down the service, and then start again. The meaning of Linux runlevel: usually there are several runlevel:runlevel System state 0 halt the System 1 single user mode 2 BAS IC Multi User mode 3 Multi user mode 5 Multi user mode with GUI 6 reboot the system S a single user mode RunLevel command to view when Pre-run level. The init command changes the current run level.
============
In Ubuntu, there is no chkconfig command to manage the service RunLevel, although it cannot be managed with this command, but it can be used to view the service running state.
So you can still install it: sudo apt-get install chkconfig and then Chkconfig--list.
In Ubuntu there is a chkconfig in place of the command sysv-rc-conf, installation method: sudo apt-get install sysv-rc-conf. This command is used in the same way as Chkconfig.
A bit different, the specific use of Baidu or Google will know
There is also a graphical interface management tool for the service in Ubuntu boot-up Manager, abbreviated as: BUM. Installing the sudo apt-get Install bum use method is not much to do introduction
There are specific service content for each service
