MySQL 在 XAMPP 上意外关闭 - 在 IP 上创建服务器套接字：'::'

Question

我对 XAMPP 还是很陌生，它一直运行良好，直到我今天早上开始工作。这是错误日志文件信息。当我尝试启动 MySQL 时，它会打开然后停止。如果需要，我宁愿不重新安装，但如果需要的话可以。

这里是 my.ini 文件。

# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client]
# password       = your_password 
port=3307
socket="C:/xampp/mysql/mysql.sock"

Answer 1

注意！请不要删除 ibdata1 文件！ 首先备份 MySQL 文件夹 'mysql/data'

1. 将mysql/data文件夹中的所有文件+文件夹备份到mysql/data_old_backup

2. 有时 XAMPP MySQL 服务停止工作，在我的例子中，XAMPP 控制面板中的原因是：“错误：MySQL 意外关闭”并带有相同的错误日志

解决方案：

1. 我已经修复了同样的问题，将所有文件+文件夹从 xampp/mysql/backup/ 复制（+覆盖）到 xampp/mysql/data/
2. 您可能在步骤 1 之后丢失了您的 mysql 根密码，您的 mysql 密码现在为空。
3. 现在，从 "mysql/data_old_backup/ibdata1" 的备份文件夹中复制（+覆盖）文件 ibdata1 到 xampp/mysql/data/
   （因为您想恢复所有数据）
4. 从 XAMPP 控制面板启动 MySQL。

它应该可以工作
