ubuntu-18.04 设置开机启动脚本

在设置frp的时候,需要添加到开机自启动项目中。

不过ubuntu-18.04不能像ubuntu14一样通过编辑rc.local来设置开机启动脚本,通过下列简单设置后,可以使rc.local重新发挥作用。

  1. 建立rc-local.service文件

sudo vi /etc/systemd/system/rc-local .service

  1. 将下列内容复制进rc-local.service文件
[Unit]
Description=/etc/rc.local Compatibility
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
  1. 创建文件rc.local

sudo vi /etc/rc.local

  1. 将下列内容复制进rc.local文件
#!/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.
echo "看到这行字,说明添加自启动脚本成功。" > /usr/local/test.log
exit 0
  1. 给rc.local加上权限,启用服务

    sudo chmod +x /etc/rc.local
    sudo systemctl enable rc-local
    
  2. 启动服务并检查状态

sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
  1. 重启并检查test.log文件

cat /usr/local/test.log
