Linux设置服务或者程序和脚本开机启动

Posted 2021-06-08 白-胖-子

设定服务开机启动

设定某服务开机自启，相当于chkconfig name on

systemctl enable name.service

设定某服务开机禁止启动：相当于chkconfig name off

systemctl disable name.service

查看所有服务的开机自启状态，相当于chkconfig --list

systemctl list-unit-files --type service

用来列出该服务在哪些运行级别下启用和禁用：chkconfig –list name

ls /etc/systemd/system/*.wants/name.service

查看服务是否开机自启：

systemctl is-enabled name.service

列出失败的服务

systemctl --failed --type=service

开机并立即启动或停止

systemctl enable --now postfix
systemctl disable --now postfix

设定脚本或非独立程序

• 将脚本或者程序写进/etc/rc.local 文件
• /etc/rc.local 文件需要拥有执行权限（Ubuntu默认没有）
• 脚本或者程序需要拥有执行权限

ll /etc/rc.local 
lrwxrwxrwx. 1 root root 13 11月  8 2019 /etc/rc.local -> rc.d/rc.local
[02:32:47 root@C8-3-55 ~]#cat /etc/rc.local 
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
