安裝 MetroCluster tiebreaker 1.5 相依性

貢獻者
PDF

視主機 Linux 作業系統而定、您必須先安裝 MySQL 或 MariaDB 伺服器、才能安裝或升級 tiebreaker 軟體。

步驟

  1. 安裝 JDK

  2. 安裝及設定Vault

  3. 安裝MySQL或MariaDB伺服器：

    如果Linux主機是

    然後…​

    Red Hat Enterprise Linux 7/CentOS 7.

    在 Red Hat Enterprise Linux 7 或 CentOS 7 上安裝 MySQL Server 5.5.30 或更新版本和 5.6.x 版本

    Red Hat Enterprise Linux 8

    在 Red Hat Enterprise Linux 8 上安裝 MariaDB 伺服器

安裝 JDK

在安裝或升級 tiebreaker 軟體之前、您必須在主機系統上安裝 JDK 。Tiebreaker 1.5 及更新版本支援 OpenJDK 17 、 18 或 19 。

步驟

  1. 以「root」使用者或可變更為進階權限模式的Sudo使用者身分登入。

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

  2. 檢查可用的 JDK 版本：

    yum search openjdk

  3. 安裝 JDK 17 、 18 或 19 。

    下列命令會安裝 JDK 17 ：

    yum install java-17-openjdk

  4. 驗證安裝：

    java -version

    成功安裝時會顯示下列輸出：

    openjdk version "17.0.2" 2022-01-18 LTS
OpenJDK Runtime Environment 21.9 (build 17.0.2+8-LTS)
OpenJDK 64-Bit Server VM 21.9 (build 17.0.2+8-LTS, mixed mode, sharing)

安裝及設定Vault

如果您沒有或想要使用本機Vault伺服器、則必須安裝Vault。您可以參閱本標準程序來安裝Vault、或參閱《橋式安裝說明》以取得替代準則。

註 如果您的網路中有Vault伺服器、您可以設定MetroCluster 使用該Vault安裝的還原斷路器主機。如果您這麼做、就不需要在主機上安裝 Vault 。
步驟

  1. 瀏覽至 /bin 目錄：

    [root@mcctb] cd /bin

  2. 下載Vault壓縮檔。

    [root@mcctb /bin]#  curl -sO https://releases.hashicorp.com/vault/1.12.2/vault_1.12.2_linux_amd64.zip

  3. 解壓縮Vault檔案。

    [root@mcctb /bin]# unzip vault_1.12.2_linux_amd64.zip
Archive:  vault_1.12.2_linux_amd64.zip
  inflating: vault

  4. 驗證安裝。

    [root@mcctb /bin]# vault -version
Vault v1.12.2 (415e1fe3118eebd5df6cb60d13defdc01aa17b03), built 2022-11-23T12:53:46Z

  5. 瀏覽至 /root 目錄：

    [root@mcctb /bin] cd /root

  6. 在下建立 Vault 組態檔案 /root 目錄。

    的 [root@mcctb ~] 提示、複製並執行下列命令以建立 config.hcl 檔案：

    # cat > config.hcl << EOF
 storage "file" {
  address = "127.0.0.1:8500"
  path    = "/mcctb_vdata/data"
 }
 listener "tcp" {
   address     = "127.0.0.1:8200"
   tls_disable = 1
 }
EOF

  7. 啟動Vault伺服器：

    [root@mcctb ~] vault server -config config.hcl &

  8. 匯出Vault位址。

    [root@mcctb ~]# export VAULT_ADDR="http://127.0.0.1:8200"

  9. 初始化Vault。

    [root@mcctb ~]# vault operator init

Initial Root Token: <initial_root_token_id>


Vault initialized with 5 key shares and a key threshold of 3. Please securely
distribute the key shares printed above. When the Vault is re-sealed,
restarted, or stopped, you must supply at least 3 of these keys to unseal it
before it can start servicing requests.

Vault does not store the generated root key. Without at least 3 keys to
reconstruct the root key, Vault will remain permanently sealed!

It is possible to generate new unseal keys, provided you have a quorum of
existing unseal keys shares. See "vault operator rekey" for more information.
    重要 您必須將金鑰 ID 和初始根權杖記錄並儲存在安全位置、以便稍後在程序中使用。

  10. 匯出Vault根憑證。

    [root@mcctb ~]#  export VAULT_TOKEN="<initial_root_token_id>"

  11. 使用建立的五個金鑰中的任何三個來解除保存 Vault 的密封。

    您必須執行 vault operator unseal 三個按鍵的命令：

    1. 使用第一個金鑰來解除保存資料保險箱的密封：

      [root@mcctb ~]# vault operator unseal

      註 安裝MetroCluster 完ESITiebreaker時、系統會提示您使用此功能。如果您想要變更解封Vault的方法、則需要解除安裝並重新安裝MetroCluster 還原器軟體。

在 Red Hat Enterprise Linux 7 或 CentOS 7 上安裝 MySQL Server 5.5.30 或更新版本和 5.6.x 版本

安裝或升級Tiebreaker軟體之前、您必須先在主機系統上安裝MySQL Server 5.5.30或更新版本及5.6.x版本。對於 Red Hat Enterprise Linux 8 、 安裝 MariaDB 伺服器。

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. 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!

  ... 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>
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 17
Server version: 5.6.29 MySQL Community Server (GPL)

mysql>

    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 使用者或可Sudo進階權限模式的使用者。

    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
Loaded plugins: fastestmirror, langpacks

  3. 啟動MariaDB伺服器：

    [root@mcctb ~]# systemcl start MariaDB

  4. 確認MariaDB伺服器已啟動：

    [root@mcctb ~]# systemctl狀態MariaDB

    [root@mcctb ~]# systemctl status mariadb
mariadb.service - MariaDB database server
...
Nov 08 21:28:59 mcctb systemd[1]: Starting MariaDB database server...
...
Nov 08 21:29:01 mcctb systemd[1]: Started MariaDB database server.

  5. 設定安全性和密碼設定：

    註 當系統提示您輸入 root 密碼時、請將其保留空白、然後按 Enter 鍵繼續設定安全性和密碼設定。 
    root@localhost systemd]# mysql_secure_installation

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
