MySQL database error The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid)

Introduction
  Because the server is powered off, the database cannot be connected. I found a lot of examples on the Internet. What permissions are not enough, and what needs to run the initialization script?They did not solve the problem in a timely and fast manner, but brought more problems.

As shown in the figure, this error is reported as soon as the database service is started.Checked for a long time

Solutionp>

Directly find the my.cnf file in the /etc directory and replace the following configuration into it.Then modify it according to your own directory configuration

[mysqld]bind-address=0.0.0.0port=3306user=mysql## This place is modified to the path of personal configurationbasedir=/usr/local/mysqldatadir=/data/mysqlsocket=/tmp/mysql.socklog-error=/data/mysql/mysql.errpid-file=/data/mysql/mysql.pid#character configcharacter_set_server=utf8mb4symbolic-links=0explicit_defaults_for_timestamp=true

One thing to note here is that if the configuration is not appropriate, the following error will appear, but don't worry, there must be a pid file under the path you configured.So either specify the file directly or delete it. After the database service is started, it will be recreated.

Finally perfect launch

The method is real and effective, if it's not suitable, please @blogger in the comment area, the blogger must help solve it!
