记录一下openGauss自启动的设置

0.碎碎念

    看了好几篇笔记照抄都不行，搞不明白，东拼西凑又成功了，顺便记录一下，希望能帮到别人。

1.版本

    iso:openEuler-22.03-LTS-SP4-aarch64-dvd.iso
    openGauss:openGauss-Server-6.0.0-openEuler22.03-x86_64.tar.bz2我是安装的单机
    安装路径：/opt/software/openGauss/openGauss

2.配置

    在/usr/lib/systemd/system下创建opengauss.service

[Unit]
Description=openGauss
Documentation=openGauss Server
After=syslog.target
After=network.target[Service]

具体含义可以看这个大佬的帖子：openGauss 开机自启动
创建之后走三个命令：

systemctl daemon-reload
systemctl enable opengauss.service
systemctl start opengauss.service

然后我再去看就可以了…

systemctl status opengauss.service
#其他命令
systemctl restart opengauss.service
