--explicit_defaults_for_timestamp server option (see documentation
for more details).

       number 1625987

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. 確認MySQL伺服器正在執行：

    [root@mcctb ~]#服務mysqLD狀態

    mysqld (pid  2739) is running...

  9. 設定安全性和密碼設定：

    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!

  10. 驗證MySQL登入是否正常運作：

    Enter password: <configured_password>

啟用 MySQL 自動啟動設定

您應該確認MySQL精靈的自動啟動功能已開啟。開啟MySQL精靈會在MetroCluster 系統重新開機時、自動重新啟動MySQL。如果MySQL精靈未執行、則tiebreaker軟體會繼續執行、但無法重新啟動、也無法進行組態變更。

步驟

  1. 驗證MySQL在開機時是否已啟用自動啟動：

    [root@mcctb ~]# systemctl list-unit-filesmysqld.service`

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

    如果MySQL在開機時未啟用自動啟動、請參閱MySQL文件、以啟用安裝的自動啟動功能。

在 Red Hat Enterprise Linux 8 上安裝 MariaDB 伺服器

您必須先在主機系統上安裝MariaDB伺服器、才能安裝或升級tiebreaker軟體。 對於 Red Hat Enterprise Linux 7 或 CentOS 7 、 安裝 MySQL Server。

開始之前

您的主機系統必須在Red Hat Enterprise Linux（RHEL）8上執行。

步驟

  1. 以登入 root 使用者：

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

  2. 安裝 MariaDB 伺服器：

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

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

啟用 MariaDB 伺服器的自動啟動設定

您應該確認 MariaDB 伺服器的自動啟動功能已開啟。如果您未啟用自動啟動功能、MetroCluster 且駐留的系統必須重新開機、則tiebreaker軟體會繼續執行、但無法重新啟動MariaDB服務、也無法進行組態變更。

步驟

  1. 啟用自動啟動服務：

    [root@mcctb ~]# systemctl enable mariadb.service`

  2. 確認已啟用MariaDB、以便在開機時自動啟動：

    [root@mcctb ~]# systemctl list-unit-filesmariadb.service`

    UNIT FILE          State
------------------ ----------
mariadb.service    enabled
