安装 Tiebreaker 软件

提供者 netapp-thomi NetAppZacharyWambold netapp-martyh netapp-aherbin netapp-ivanad

Tiebreaker 软件可为集群存储环境提供监控功能。此外,它还会在发生节点连接问题和站点灾难时发送 SNMP 通知。

必须安装和配置 MetroCluster 软件。

安装或升级 Tiebreaker 软件的系统要求

Tiebreaker 软件安装在第三个站点上,该软件可以区分交换机间链路( ISL )故障(站点间链路关闭时)和站点故障。在本地计算机上安装或升级 Tiebreaker 软件以监控 MetroCluster 配置之前,主机系统必须满足特定要求。

MetroCluster Tiebreaker 软件具有以下监控功能和要求:

  • 对于不同的 MetroCluster 配置,不需要特殊配置。

  • 可同时监控多达 15 个 MetroCluster 配置。

    注 每个 MetroCluster 配置只能有一个 MetroCluster Tiebreaker 监控器,以避免与多个 Tiebreaker 监控器发生任何冲突。
  • 支持 MetroCluster IP , MetroCluster FC 和延伸型 MetroCluster 配置的组合。

  • 硬件和软件:

    • ONTAP 8.3.x , 9.0 , 9.1 , 9.2 , 9.3 , 9.4 , 9.5 , 9.6 , 9.7 , 9.8 , 9.9.1 或 9.10.1

  • Red Hat Enterprise Linux 7 到 7.9 或 8 到 8.4 或 CentOS 7 到 7.9 64 位(物理安装或虚拟机)

    • MariaDB 5.5.52.x/MySQL Server 5.6x

    • 4 GB RAM

    • 打开 Java Runtime Environment 8.

  • 磁盘容量: 8 GB

  • 用户: root 访问权限

  • 防火墙:

    • 直接访问以设置 AutoSupport 消息

    • SSH (端口 22/TCP ), HTTPS (端口 443/TCP )和 ping ( ICMP )

  • 不支持在启用了 FIPS 的主机上安装。

安装 MetroCluster Tiebreaker 依赖关系

在安装或升级 Tiebreaker 软件之前,您必须根据主机所在的 Linux 操作系统安装 MySQL 或 MariaDB 服务器。

步骤
  1. 安装 Java Runtime Environment 。

  2. 安装 MySQL 或 MariaDB 服务器:

    如果 Linux 主机为

    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.

    Starting mysqld:                                           [  OK  ]
  8. 确认 MySQL 服务器正在运行:

    ` 根@mcctb ~ ]# service mysqld status`

    mysqld (pid  2739) is running...
  9. 配置安全性和密码设置:

    ` 根@mcctb ~ ]# mysql_secure 安装`

    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!
    
     Cleaning up...
  10. 验证 MySQL 登录是否正常工作:

    ` 根@mcctb ~ ]# mysql -u root – p`

    Enter password: <configured_password>
    Welcome to the MySQL monitor.  Commands end with ; or \g.
    Your MySQL connection id is 17

    Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
    mysql>

    如果 MySQL 登录正常,输出将在 mysql> 提示符处结束。

启用 MySQL 自动启动设置

您应确保已为 MySQL deamon 启用自动启动功能。如果 MetroCluster Tiebreaker 软件所在的系统重新启动,则打开 MySQL 守护进程会自动重新启动 MySQL 。如果 MySQL 守护进程未运行, Tiebreaker 软件将继续运行,但无法重新启动,并且无法更改配置。

步骤
  1. 验证是否已启用 MySQL 在启动时自动启动:

    ` 根@mcctb ~ ]# systemctl list-unit-files mysqld.service`

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

    如果在启动时未启用 MySQL 自动启动,请参见 MySQL 文档为您的安装启用自动启动功能。

在 Red Hat Enterprise Linux 8 上安装 MariaDB 服务器

在安装或升级 Tiebreaker 软件之前,必须在主机系统上安装 MariaDB 服务器。

为 MariaDB 启用自动启动设置

您应确保已为 MariaDB 启用自动启动功能。如果不启用自动启动功能,并且 MetroCluster Tiebreaker 软件所在的系统必须重新启动,则 Tiebreaker 软件将继续运行,但无法重新启动 MariaDB 服务,也无法更改配置。

步骤
  1. 启用自动启动服务:

    ` 根@mcctb ~ ]# systemctl enable mariadb.service`

  2. 验证启动时 MariaDB 是否已启用自动启动:

    ` 根@mcctb ~ ]# systemctl list-unit-files mariadb.service`

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

安装或升级软件包

您必须在本地计算机上安装或升级 MetroCluster Tiebreaker 软件,才能监控 MetroCluster 配置。

  • 存储系统必须运行 ONTAP 8.3.x 或更高版本。

  • 您必须已使用 yum install java-1.8.0-OpenJDK 命令安装 OpenJDK 。

步骤
  1. 下载 "NetApp-MetroCluster-Tiebreaker 软件 -1.3-1.x86_64 : rpm" 文件。

    注 如果输入的 MySQL root 密码不正确, Tiebreaker 软件会指示已成功安装该密码,但会显示 Access Denied 消息。要解决问题描述问题,您必须使用 rpm -e 命令卸载 Tiebreaker 软件,然后使用正确的 MySQL root 密码重新安装该软件。
  4. 通过打开从 Tiebreaker 主机到每个节点管理 LIF 和集群管理 LIF 的 SSH 连接,验证 Tiebreaker 与 MetroCluster 软件的连接。

升级运行 Tiebreaker 监控器的主机

如果您在升级之前将 Tiebreaker 监控器置于观察模式,则可以升级运行该监控器的主机,而不会造成任何中断。

步骤
  1. 验证监控器是否处于观察模式:

    m监控器显示– status

    NetApp MetroCluster Tiebreaker:> monitor show -status
    MetroCluster: cluster_A
        Disaster: false
        Monitor State: Normal
        Observer Mode: true
        Silent Period: 15
        Override Vetoes: false
        Cluster: cluster_Ba(UUID:4d9ccf24-080f-11e4-9df2-00a098168e7c)
            Reachable: true
            All-Links-Severed: FALSE
                Node: mcc5-a1(UUID:78b44707-0809-11e4-9be1-e50dab9e83e1)
                    Reachable: true
                    All-Links-Severed: FALSE
                    State: normal
                Node: mcc5-a2(UUID:9a8b1059-0809-11e4-9f5e-8d97cdec7102)
                    Reachable: true
                    All-Links-Severed: FALSE
                    State: normal
        Cluster: cluster_B(UUID:70dacd3b-0823-11e4-a7b9-00a0981693c4)
            Reachable: true
            All-Links-Severed: FALSE
                Node: mcc5-b1(UUID:961fce7d-081d-11e4-9ebf-2f295df8fcb3)
                    Reachable: true
                    All-Links-Severed: FALSE
                    State: normal
                Node: mcc5-b2(UUID:9393262d-081d-11e4-80d5-6b30884058dc)
                    Reachable: true
                    All-Links-Severed: FALSE
                    State: normal
  2. 将所有显示器更改为观察者模式。

    NetApp MetroCluster Tiebreaker :> monitor modify -monitor-name _monitor_name_ -observer-mode true
  3. 要升级 Tiebreaker 主机,请按照以下操作步骤中的所有步骤进行操作:

  4. 禁用观察模式可将所有显示器移回联机模式。

    NetApp MetroCluster Tiebreaker :> monitor modify -monitor-name _monitor_name_ -observer-mode false

为 Tiebreaker 软件选择 NTP 源

您应使用 Tiebreaker 软件的本地网络时间协议( NTP )源。它不应使用与 Tiebreaker 软件监控的 MetroCluster 站点相同的源。
