MySQL 服务器无法启动

Question

我使用 apt 安装了 MySQL-server-5.7：

apt-get install mysql-server-5.7

但是当我想使用以下方法启动服务器时：systemctl start mysql我出现了错误。

使用service msyql status查看状态，我收到错误消息：

mysql.service - MySQL Community Server
    loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset:enabled)
    Acitve: inactive(dead) .......
    Process: 2490 ExecStartPre=/usr/share/mysql/mysql-systemd-start pre(code=exited, status=1/FAILURE)

.........: Failed to start MYSQL Community Server.
.........: mysql.service: Unit entered failed state.
........................................
........................................
.........: Failed to start MySQL COmmunity Server.

如何解决？谢谢。

Answer 1

在你的日志中我看到

无法创建 unix 套接字锁文件 /var/run/mysqld/mysqld.sock.lock

如果目录不存在，则创建该目录：sudo mkdir /var/run/mysqld。更改所有权：sudo chown mysql:mysql /var/run/mysqld。
