错误：MySQL 意外关闭。插件“反馈”已禁用

Question

今天我运行MySQL，MySQL 不工作，在控制台中给出以下错误：

8:30:43 AM  [mysql]     Error: MySQL shutdown unexpectedly.
8:30:43 AM  [mysql]     This may be due to a blocked port, missing dependencies, 
8:30:43 AM  [mysql]     improper privileges, a crash, or a shutdown by another method.

检查“/xampp/mysql/data/mysql_error.log”文件时，我得到：

Answer 1

删除这些文件并重新启动mysql服务。

/var/lib/mysqld/ib_logfile0
/var/lib/mysql/ib_logfile1
/var/lib/mysql/aria_log_control

Answer 2

当 XAMPP 或 MAMP 配置为在系统启动时启动 MySQL 和 PHP 并且默认情况下 MySQL 使用端口 3306 时，经常会出现此错误。 我们必须像这样将此端口从旧端口更改为新端口：

• 首先，您必须打开XAMPP控制面板。
• 单击MySQL配置按钮->单击my.ini文件
• 它将在记事本中打开，之后你必须在两个地方找到并更改端口号从3306到3307
• 保存。

这里：

# The following options will be passed to all MySQL clients
[client]
Password = your_password   
port =  3306  #--->  3307  
socket =  "/ xampp / mysql / mysql.sock"

还有这里：

The MySQL server 
[ mysqld ] 
port =  3306  #--->  3307 
socket =  "/ xampp / mysql / mysql.sock"
