Linux parrot 4.14.0-parrot2-amd64 #1 SMP Parrot 4.14.2-1parrot2 (2017-12-05) x86_64 GNU/Linux
我最近删除了MySQL和MariaDB，但是当我使用此命令重新安装它时
$sudo apt-get install default-mysql-server-core
$sudo apt-get install default-mysql-server-corebut
现在，当我使用命令
启动MySQL服务时$service mysql start
我收到了这个错误
Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
当我在终端输入 mysql 时，我得到了这个
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111 "Connection refused"
$systemctl status mysql.service

我也谷歌并得到一些答案，因为存储空间不足而发生这种情况，但这似乎不是存储问题。
