我需要mariadb 10.1来满足我的要求。每次我重新启动系统，我得到以下错误。
错误2002（hy000）：无法通过套接字'/var/run/mysqld/mysqld.sock'（2“没有这样的文件或目录”）连接到本地mysql服务器
我尝试了一些在互联网上找到的解决方案，但似乎没有一个是有效的
尝试手动创建所有者为mysql的sock文件。
尝试重新启动mysql服务器，出现错误。
正在运行的mysql服务状态

唯一可行的解决方案是从系统中清除mysql并重新安装它。

sudo apt-get --purge remove "mysql*"
sudo apt update -y
sudo apt install -y mariadb-server
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

但下次我启动系统时，它会给出相同的错误sock文件丢失。有解决办法吗。文件丢失有具体原因吗？
谢谢你。
