Debian 9/Ubuntu 17+添加rc.local开机自启的方法

说明:很多时候有些程序或者脚本都需要添加开机自启,最简单的方法就是使用rc.local自启,不过由于系统版本更替,很多新版本系统都没有rc.local文件了,比如Debian 9Ubuntu 17.10Ubuntu 18.04。这时候就需要我们手动设置下。

方法

1、添加rc-local.service

#以下为一整条命令,一起复制运行
cat > /etc/systemd/system/rc-local.service <<EOF
[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
EOF

2、新建rc-local文件

#以下为一整条命令,一起复制运行
cat > /etc/rc.local <<EOF
#!/bin/sh
#
# 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
EOF

3、添加权限并设置开机自启

chmod +x /etc/rc.local
systemctl enable rc-local
systemctl start rc-local.service

检查状态:

systemctl status rc-local.service

返回Active:active信息,则成功。
