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 mcctb 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
strongly recommended for production servers.
.....Output truncated.....
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]

  8. MySQL 서버가 실행 중인지 확인합니다.

    '[root@mcctb~]#service mysqld status'

    mysqld (pid  2739) is running...

  9. 보안 및 암호 설정 구성:

    '[root@mctb~]#mysql_secure_installation'

    NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
       SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

 In order to log into MySQL to secure it, we'll need the current
 password for the root user.  If you've just installed MySQL, and
 you haven't set the root password yet, the password will be blank,
 so you should just press enter here.

 Enter current password for root (enter for none):   <== on default install
                                                         hit enter here
 OK, successfully used password, moving on...

 Setting the root password ensures that nobody can log into the MySQL
 root user without the proper authorization.

 Set root password? [Y/n] y
 New password:
 Re-enter new password:
 Password updated successfully!
 Reloading privilege tables..
  ... Success!

 By default, a MySQL installation has an anonymous user, allowing anyone
 to log into MySQL without having to have a user account created for
 them.  This is intended only for testing, and to make the installation
 go a bit smoother.  You should remove them before moving into a
 production environment.

 Remove anonymous users? [Y/n] y
  ... Success!

 Normally, root should only be allowed to connect from 'localhost'.  This
 ensures that someone cannot guess at the root password from the network.

 Disallow root login remotely? [Y/n] y
  ... Success!

 By default, MySQL comes with a database named 'test' that anyone can
 access.  This is also intended only for testing, and should be removed
 before moving into a production environment.

 Remove test database and access to it? [Y/n] y
  - Dropping test database...
 ERROR 1008 (HY000) at line 1: Can't drop database 'test';
 database doesn't exist
  ... Failed!  Not critical, keep moving...
  - Removing privileges on test database...
  ... Success!

 Reloading the privilege tables will ensure that all changes made so far
 will take effect immediately.

 Reload privilege tables now? [Y/n] y
  ... Success!

 All done!  If you've completed all of the above steps, your MySQL
 installation should now be secure.

 Thanks for using MySQL!

MySQL 자동 시작 설정을 활성화합니다

MySQL 데몬에 대해 자동 시작 기능이 설정되어 있는지 확인해야 합니다. MySQL 데몬을 켜면 MetroCluster Tiebreaker 소프트웨어가 상주하는 시스템이 재부팅될 경우 MySQL이 자동으로 다시 시작됩니다. MySQL 데몬이 실행되고 있지 않으면 Tiebreaker 소프트웨어가 계속 실행되지만 다시 시작할 수 없으며 구성을 변경할 수 없습니다.

단계

  1. 부팅할 때 MySQL이 자동 시작되도록 설정되었는지 확인합니다.

    ([root@mcctb~]#systemctl list-unit-files mysqld.service`)

    UNIT FILE          State
------------------ ----------
mysqld.service     enabled

    부팅할 때 MySQL이 자동 시작되도록 설정되지 않은 경우 MySQL 설명서를 참조하여 설치에 대한 자동 시작 기능을 활성화하십시오.

Red Hat Enterprise Linux 8에 MariaDB 서버를 설치합니다

Tiebreaker 소프트웨어를 설치하거나 업그레이드하기 전에 호스트 시스템에 MariaDB 서버를 설치해야 합니다. Red Hat Enterprise Linux 7 또는 CentOS 7의 경우 MySQL Server를 설치합니다.

시작하기 전에

호스트 시스템은 Red Hat Enterprise Linux(RHEL) 8에서 실행 중이어야 합니다.

단계

  1. 로 로그인합니다 root 사용자.

    login as: root
root@mcctb's password:
Last login: Fri Jan  8 21:33:00 2017 from host.domain.com

  2. MariaDB 서버 설치:

    '[root@mctb~]#yum install MariaDB-server.x86_64'

    [root@mcctb ~]# yum install mariadb-server.x86_64
