我在安装在 Ubuntu 18.04 vps 服务器上的 xampp 上运行 php 脚本，我遇到了一个正在消耗 CPU 的 mysql 进程。我认为这与文件有关/opt/lampp/var/mysql/vps800313.err。
如果您知道如何禁用它，请查看屏幕截图并发表评论。
** /opt/lampp/etc/my.cnf 文件：**
# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL
plays
# an important part, or systems up to 128M where MySQL is used
together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /opt/lampp/var/mysql) 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 =3306
socket =/opt/lampp/var/mysql/mysql.sock
# Here follows entries for some specific programs
# The MySQL server

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

host.
# 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
#master-port = <port>
