Resolves the MySQL error:host is blocked because of many connection errors issues

# mysqladmin Flush-hosts

Now we go into the MySQL editor my.cnf

# VI/ETC/MY.CNF

Then add in the inside

max_connect_errors=10000

# Service Mysqld Restart

Then restart the MySQL database server, if you do not have the server permissions we can use the command mode to set

# mysql-uroot-p
# mysql> SET GLOBAL max_connect_errors=10000;

In fact, this method is not the root of the solution we can try to set the MySQL connection wait when the long wait_timeout settings also in my.cnf to find an increase wait_timeout= 5; This 5 is a second OH.
