debian9和ubuntu18.04默认已经没有rc.local文件,但设置启动执行命令这又是最简单的办法需要手动开启
新建 /etc/systemd/system/rc-local.service 文件
[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新建/etc/rc.local文件
#!/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添加权限设置自启
chmod +x /etc/rc.local
systemctl enable rc-local
systemctl start rc-local.service检测启动状态
systemctl status rc-local.service吧命令添加到/etc/rc.local文件 exit 0前即可
