Debian 9/Ubuntu 17+ rc.local开机自启

/ 1

习惯了使用rc.local设置开机自启,不过Debian 9/Ubuntu 17+默认已经没有rc.local文件了,我们需要手动自己编辑。
1. 新增rc-local.service文件:

vi /etc/systemd/system/rc-local.service
写入下面内容并保存:
[Unit]
Description=/etc/rc.local
ConditionPathExists=/etc/rc.local

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99

[Install]
WantedBy=multi-user.target

2. 新增rc-local文件:

vi /etc/rc.local
写入下面内容并保存:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
exit 0

3. 添加权限并设置开机自启并启动脚本:

chmod +x /etc/rc.local
systemctl enable rc-local
systemctl start rc-local.service
4. 检查服务状态:

systemctl status rc-local.service
返回Active:active信息,表示成功了,然后就可以在/etc/rc.loacl中的exit前增加任意你想启动的脚本了。
