Cause.
The reason why table ‘mysql.host’ does not exist is because after a new installation of the mysql service, it is generally necessary to perform database initialization operations , thus generating a table related to permissions, execute the following command.

/usr/bin/mysql_install_db –user=mysql

Note: The mysql_install_db in the above command is related to the location of your installed mysql service, if you don’t know where it is, you can use find/-name mysql_install_db to find its location, and then execute the above command.

[root@hadoop11 mysql]# find/-name mysql_install_db
/usr/bin/mysql_install_db
