升级到Debian9后,我们发现系统默认不带/etc/rc.local文件,但rc.local服务仍然保留
补齐缺失文件,让Debian9通过编辑/etc/rc.loacl文件为我们的服务添加开机自启动
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=0StandardOutput=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 -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 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。
最后我们就可以在/etc/rc.local
里,添加开机的自启命令什么的了。记住添加在exit 0
之前。
注意:更改自启脚本后,需要重新运行一下命令已使其生效。
systemctl enable rc-local systemctl start rc-local.service
