Error in PREIN scriptlet in rpm package MariaDB-server-5.5.36-1.el6.x86_64

**************************************** **************************
A MySQL or MariaDB server package (mysql-server-5.1.71-1.el6.x86_64) is installed.

The current MariaDB server package is provided by a different
Vendor (CentOS) than Monty Program AB. Some files may be installed
To different locations, including log files and the service
Startup script in/etc/init. d /.

Upgrading directly from MySQL 5.1 to MariaDB 5.5 may not
Be safe in all cases. A manual dump and restore using mysqldump is
Recommended. It is important to review the MariaDB manual's Upgrading
Section for version-specific incompatibilities.

A manual upgrade is required.

-Ensure that you have a complete, working backup of your data and my. cnf
Files
-Shut down the MySQL server cleanly
-Remove the existing MySQL packages. Usually this command will
List the packages you shoshould remove:
Rpm-qa | grep-I '^ mysql -'

You may choose to use 'rpm -- nodeps-ev <package-name> 'to remove
The package which contains the mysqlclient shared library.
Library will be reinstalled by the MariaDB-shared package.
-Install the new MariaDB packages supplied by Monty Program AB
-Ensure that the MariaDB server is started
-Run the 'mysql _ upload' program

This is a brief description of the upgrade process. Important details
Can be found in the MariaDB manual, in the Upgrading section.

3. Start MariaDB

#/Etc/init. d/mysqld start
Initializing MySQL database: WARNING: The host 'cloud-Q2 'cocould not be looked up with resolveip.
This probably means that your libc libraries are not 100% compatible
With this binary MySQL version. The MySQL daemon, mysqld, shocould work
Normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
When specifying MySQL privileges!
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
Support-files/mysql. server to the right place for your system

Please remember to set a password for the MySQL root USER!
To do so, start the server, then issue the following commands:

/Usr/bin/mysqladmin-u root password 'new-password'
/Usr/bin/mysqladmin-u root-h Cloud-Q2 password 'new-password'

Alternatively you can run:
/Usr/bin/mysql_secure_installation

Which will also give you the option of removing the test
Databases and anonymous user created by default. This is
Stronugly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon:
Cd/usr;/usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
Mysql-test-run.pl for cd/usr/mysql-test; perl

Please report any problems with the/usr/bin/mysqlbug script!

[OK]
Starting mysqld: [OK]

4. Set a password for MariaDB

#/Usr/bin/mysqladmin-u root password 'adminadmin'

Log onto MariaDB

MySQL [(none)]> use mysql;
MySQL [mysql]> update user set host = '%' where user = 'root' and host = '2017. 0.0.1 ';
MySQL [mysql]> grant all privileges on *. * to 'root' @ '%' identified by 'adminadmin' with grant option;
MySQL [mysql]> flush privileges;

5. Allow the firewall to pass port 3306

# Vi/etc/sysconfig/iptables

Add the following content:

-A input-m state -- state NEW-m tcp-p tcp -- dport 3306-j ACCEPT

Save and exit editing
Restart the Firewall Service

# Service iptables restart

Remote Connection check. Everything is OK!
