Managiing Services On Centos 6

Check Services yang ada pada linux :

#chkconfig  --list

Tampilanya  :

NetworkManager 0:off 1:off 2:on 3:on 4:on 5:on 6:off
acpid           0:off 1:off 2:on 3:on 4:on 5:on 6:off
atd             0:off 1:off 2:off 3:on 4:on 5:on 6:off
auditd         0:off 1:off 2:on 3:on 4:on 5:on 6:off
autofs         0:off 1:off 2:off 3:on 4:on 5:on 6:off
blk-availability 0:off 1:on 2:on 3:on 4:on 5:on 6:off

firstboot       0:off 1:off 2:off 3:off 4:off 5:off 6:off
haldaemon       0:off 1:off 2:off 3:on 4:on 5:on 6:off

untuk filternya  bisa menggunakan |grep

#chkconfig --list |grep httpd 

hasilnya :

httpd           0:off 1:off 2:on 3:on 4:on 5:on 6:off

Untuk melihat tingkatan levelnya dalam linux :

#vi /etc/inittab

hasilnya :

# Default runlevel. The runlevels used are:

#   0 - halt (Do NOT set initdefault to this)

#   1 - Single user mode

#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)

#   3 - Full multiuser mode

#   4 - unused

#   5 - X11

#   6 - reboot (Do NOT set initdefault to this)

Cara Merubahnya :

contoh service apache (web server ) ingin runing ketika setiap kali booting .

#chkconfig --level 3 httpd on

atau jika mau dimatikan 

#chkconfig --level 3 httpd off
