安裝Tiebreaker軟體

Tiebreaker軟體提供叢集式儲存環境的監控功能。當節點連線問題和站台災難發生時、也會傳送SNMP通知。

必須安裝並設定此軟件。MetroCluster

安裝或升級斷路器軟體的系統需求

Tiebreaker軟體安裝在第三個站台、可讓軟體區分交換器間連結(ISL)故障(站台間連結中斷時)與站台故障。您的主機系統必須符合特定要求、才能在本機電腦上安裝或升級斷路器軟體、以監控MetroCluster 此功能組態。

本產品具備下列監控功能與需求:MetroCluster

  • 不需要針對不同MetroCluster 的不含資訊的組態進行特殊組態設定。

  • 監控功能MetroCluster 可同時執行多達15個的不同步組態。

    附註 每個版本的每個版本組態應只有一MetroCluster 部ESIT斷路 器監控器MetroCluster 、以避免與多部斷路器監控器發生衝突。
  • 支援MetroCluster 結合使用各種不同的知識、包括知識、MetroCluster 知識、技術、MetroCluster 技術及彈性等組態。

  • 硬體與軟體:

    • 版本8.3.x、9.0、9.1、9.2、9.3、ONTAP 9.4、9.5、9.6、9.7、9.8、 9.9.1、9.10.1或9.11.1。

  • Red Hat Enterprise Linux 7至7.9、或CentOS 7至7.9 64位元(實體安裝或虛擬機器)

    • MariaDB 5.5.52 x / MySQL Server 5.6x

    • 4 GB RAM

    • 開啟Java執行時間環境8.

  • Red Hat Enterprise Linux 8.1至8.5

    • MariaDB 10.x(使用使用「yum install MariaDB-server.x86_64」安裝的預設版本)

    • 4 GB RAM

    • 開啟Java執行時間環境8.

  • 磁碟容量:8 GB

  • 使用者:root存取權

  • 防火牆:

    • 直接存取以設定AutoSupport 資訊訊息

    • SSH(連接埠22/TCP)、HTTPS(連接埠443/TCP)及ping(ICMP)

  • 不支援在啟用FIPS的主機上安裝。

安裝MetroCluster 相依的斷點器

安裝或升級tiebreaker軟體之前、您必須先安裝MySQL或MariaDB伺服器、視主機所在的Linux作業系統而定。

步驟
  1. 安裝Java執行時間環境。

      /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.

    [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!
    
     Cleaning up...
  10. 驗證MySQL登入是否正常運作:

    Enter password: <configured_password>

    如果MySQL登入正常運作、輸出將在「mysql>」提示字元結束。

啟用MySQL自動啟動設定

您應該確定MySQL deamon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。

啟用MariaDB的自動啟動設定

您應該確定MariaDB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
    ------------------ ----------

您必須在MetroCluster 本機電腦上安裝或升級ESITirepreaker軟體、才能監控MetroCluster 各種組態。

  • 您的儲存系統必須執行ONTAP 不含更新版本的資訊。

  • 您必須使用「yum install Java-1.8.0-OpenJDK'」命令來安裝OpenJDK.

步驟
  1. 下載MetroCluster 最新版的Eetirepreaker軟體。此範例使用1.21P3-1版。

  2. 以root使用者身分登入主機。

  3. 安裝或升級Tiebreaker軟體:

    如果您…​

    發出此命令…​

    執行新安裝

    「rpm -ivh NetApp-MetroCluster-tiebreer-Software-1.21P3-1x86_64。rpm」

    系統會顯示下列輸出、以利成功安裝:

    附註 如果您輸入錯誤的MySQL根密碼、則Tiebreaker軟體會指出已成功安裝、但會顯示「拒絕存取」訊息。若要解決此問題、您必須使用「rpm -e」命令解除安裝Tiebreaker軟體、然後使用正確的MySQL root密碼重新安裝軟體。
  4. 開啟從斷路器主機到每個節點管理生命期和叢集管理生命期的SSH連線、以驗證與MetroCluster 該軟件的斷路器連線。

升級執行Tiebreaker監控的主機

如果您在升級前將監視器置於觀察者模式、則可在執行斷路器監視器的主機上進行升級、而不會造成中斷。

步驟
  1. 確認監視器處於觀察者模式:

    「監視者顯示–狀態」

    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. 將所有監視器變更為觀察者模式。

    NetApp MetroCluster Tiebreaker :> monitor modify -monitor-name _monitor_name_ -observer-mode true
  3. 若要升級Tiebreaker主機、請依照下列程序中的所有步驟進行:

  4. 停用觀察者模式、將所有監視器移回線上模式。

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

選取Tiebreaker軟體的NTP來源

您應該使用本地網路時間傳輸協定(NTP)來源來執行Tiebreaker軟體。它不應使用MetroCluster 與斷路器軟體所監控的不相同來源。
