ubuntu设置脚本开机自启动

rc-local.service flexmi@td1:~$ cd /lib/systemd/system/ flexmi@td1:/lib/systemd/system$ ls |grep rc-local.service rc-local.service rc-local.service.d flexmi@td1:/lib/systemd/system$ pwd /lib/systemd/system flexmi@td1:/lib/systemd/system$

确保有rc-local.service文件，没有手动添加，内容如下：

#flexmi@td1:/lib/systemd/system$ cat ./rc-local.service # SPDX-License-Identifier: LGPL-2.1+ # # This file is part of systemd. # # systemd is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2.1 of the License, or # (at your option) any later version. # This unit gets pulled automatically into multi-user.target by # systemd-rc-local-generator if /etc/rc.local is executable. [Unit] Description=/etc/rc.local Compatibility Documentation=man:systemd-rc-local-generator(8) ConditionFileIsExecutable=/etc/rc.local After=network.target [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 RemainAfterExit=yes GuessMainPID=no rc.local

找到rc.local文件，没有就创建在/etc目录下，内容为你需要执行的脚本内容或者你需要执行的脚本启动命令

flexmi@td1:/lib/systemd/system$ cd /etc flexmi@td1:/etc$ ls |grep rc.local rc.local flexmi@td1:/etc$ cat ./rc.local #!/bin/bash cd /home/flexmi/cmss sudo ./start.sh exit 0 flexmi@td1:/etc$

注意要给rc.local脚本文件添加执行权限

sudo chmod +x ./rc.local 启动服务 sudo systemctl enable rc-local sudo systemctl start rc-local.service sudo systemctl status rc-local.service 注意 如果服务启动失败，看看是不是rc.local的问题，脚本的开头一定要是 #!/bin/bashrc.local脚本的后面一定要加上exit 0
