无法在树莓派上安装MySQL

时间：2019-05-27 11:36:18

标签： mysql raspberry-pi raspbian

尝试在rspbian Stretch上安装MySQL时遇到很多麻烦，

所以最后我删除了所有带有sql的内容，然后又安装了mysql-server 

sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install mysql-server mysql-client

但是现在当我尝试以root身份登录时出现此错误

pi@raspberrypi:~ $ sudo mysql --user=root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket 
'/var/run/mysqld/mysqld.sock' (2 "No such file or directory")

当我尝试启动服务器时，出现此错误：

Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

日志中的错误是：

    ● mariadb.service - MariaDB 10.1.38 database server

我该如何解决这个问题？知道我已经尝试了无数种解决方案，但都没有成功

1 个答案:

答案 0 :(得分：0)

对此片段进行猜测

ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/r

mysql用户可能没有权限更新/创建指向/var/<something>的任何文件夹。
