在debian或者ubuntu上开启自启动脚本rc.local

发现 debian 或者 ubuntu 这些最新的发行版没有像红帽系那种启动脚本

发现可以用 systemd 自动把这个文件注册成服务

于是开始了尝试

贴一下脚本

touch /etc/rc.local
cat > /etc/rc.local <<-EOF
#!/bin/bash
<your_program>.sh
exit 0
EOF

chmod +x /etc/rc.local

cat > /etc/systemd/system/rc-local.service <<-EOF

systemctl enable --now rc-local.service

注意把 rc.local 里的脚本自行替换一下

最后使用 systemctl status rc-local.service 验证
