Question

我需要Mariadb 10.1来满足我的要求。每次我重新启动系统时都会出现以下错误。

ERROR 2002（HY000）：无法通过socket＆＃39; /var/run/mysqld/mysqld.sock'连接到本地MySQL服务器; （2＆＃34;没有这样的文件或目录＆＃34;）

我尝试了一些在互联网上找到的解决方案，但似乎都没有工作

尝试手动创建sock文件，其所有者为mysql。
尝试重新启动/启动mysql服务器，出错。

运行服务mysql状态

只有似乎有效的解决方案是从系统中清除mysql并重新安装它。这就是我的工作方式。

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

但是下次启动系统时，它会丢失相同的sock文件错误。有没有解决方案。文件丢失是否有特定原因？

假设你已经启用了MySQL作为服务（看起来就是这种情况），那么我建议你做一个service mysql status以查看该服务是否干净利落（如果没有它会给你看一些错误信息）。

每次重新启动系统时都会丢失Mariadb 10.1，mysqld.sock文件
