【中文标题】MySQL 在 Windows 中的 XAMPP 上不断崩溃【英文标题】：MySQL keeps crashing on XAMPP in Windows 【发布时间】：2020-11-01 12:29:06 【问题描述】：（编辑：我通过删除所有 master******.info 文件以及 multi-master.info、mysql_error.log 和 relay-bin 文件来修复它。我的数据已损坏但基本上我用this 解决了它）
我查看了 *** 上的其他帖子并尝试了一些东西，但它们不起作用，或者它们处理的错误与我的错误不同。每次我尝试启动 MySQL 时，都会得到以下输出
“错误：MySQL 意外关闭。这可能是由于端口被阻止、缺少依赖项、权限不正确、崩溃或被其他方法关闭。按“日志”按钮查看错误日志并检查 Windows 事件查看器更多线索。如果您需要更多帮助，请复制并在论坛上发布整个日志窗口"
这是 mysql_error.log 文件中的输出：

# 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
# /Users/Yousuf/Documents/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 /Users/Yousuf/Documents/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

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306

既不更改端口（在 XAMPP 设置和配置文件中）也不为绑定侦听注释任何一行（“在此处更改以进行绑定侦听”）。关于如何解决它的任何想法？
【问题讨论】：
【参考方案1】：那个my.cnf 文件是黑暗时代遗留下来的吗？好像有innodb_buffer_pool_size = 16M改成200M。
你有多少内存？您可能能够超过 200M。
当您使用它时，将innodb_log_file_size 更改为128M。
这些是十年前的默认设置（5.1 版？），但今天并不好。
如果可能，将新 WAMP 中的 my.cnf 与您正在使用的进行比较。可能还有其他事情我忘记了。
