- 安装完成后,查看
/lib/systemd/system目录,多了一个mysql后台服务
- 查看mysql后台服务状态
systemctl status mysql.service
其他
-
/lib/systemd/system目录
存放各种后台运行服务的配置文件。mysql以后台服务形式运行,开机即启动。
例如在 Ubuntu 中，我们可以通过 apt-get install mysql-server 的方式安装 MySQL，然 后通过命令systemctl start mysql启动 MySQL，通过systemctl enable mysql设置开机启 动。
之所以成为服务并且能够开机启动，是因为在 /lib/systemd/system 目录下会创建一 个 XXX.service 的配置文件，里面定义了如何启动、如何关闭。 -
/etc/apt/sources.list配置文件
定义apt命令去哪里下载ubuntn的软件
