Service指令

筆記

service指令在Linux或是Unix-Like伺服器下是很好用的指令,可以觀察每一個service daemon的狀態,包括可以隨時啟動或關閉或重啟某個服務
比如:
在prompt下鍵入"service --status-all"可以看到整個伺服器下的所有服務啟閉狀態
鍵入"service httpd start"可以啟動httpd服務;"service httpd stop"可以關閉httpd服務;"service httpd restart"可以重啟httpd服務,其他"子"令還有不太用的{condrestart|reload|status|fullstatus|graceful|help|configtest}

man service

service(8)                                                          service(8)

NAME
       service - run a System V init script

SYNOPSIS
       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION
       service  runs  a  System V init script in as predictable environment as
       possible, removing most environment variables and with current  working
       directory set to /.

       The  SCRIPT  parameter  specifies  a  System  V init script, located in
       /etc/init.d/SCRIPT.  The supported values  of  COMMAND  depend  on  the
       invoked  script,  service  passes  COMMAND  and  OPTIONS it to the init
       script unmodified.  All scripts should support at least the  start  and
       stop  commands.   As  a special case, if COMMAND is --full-restart, the
       script is run twice, first with the stop command, then with  the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with
       the status command.

FILES
       /etc/init.d
              The directory containing System V init scripts.

ENVIRONMENT
       LANG, TERM
              The only environment variables passed to the init scripts.

SEE ALSO
       chkconfig(8), ntsysv(8)
