我在我的ubuntu映像容器上安装mariadb-server，当我想启动mysql服务失败时，error.log文件包含：

首先，/ run / mysqld目录为空，我收到错误
ERROR 2002（HY000）：无法通过socket＆＃39; /var/run/mysqld/mysqld.sock'连接到本地MySQL服务器; （2）
我创建了内容为1773的mysqld.sock文件，错误已更改为＆＃39;文件或目录不存在＆＃39;到＆＃39; 111连接被拒绝＆＃39;。
问题是什么？
答案 0 :(得分：1)
你有另一个实例Docker或其他（不能告诉你整体设置是什么）使用相同的端口，它告诉你：
Can't start server: Bind on TCP/IP port. Got error: 98: Address already in use
180228 18:41:32 [ERROR] Do you already have another mysqld server running on port: 3306 ?
尝试docker ps -a查看是否还有其他可能正在使用该端口的容器。如果有，您可以单独或全部删除它们：
docker rm $(docker ps -aq)
如果您尝试绑定到主机（您的计算机的）端口以及容器，您可以运行端口扫描（search for how based on your OS）以查看它是否正在使用那里。
