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}

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.
