本文用四節點部署GaussDB T 1.0.1分佈式集羣，部署完成後再將其升級到1.0.2版本(直接安裝1.0.2版本，在安裝過程中會遇到segment fault報錯，目前尚未解決)。前期操作系統準備工作參考之前的幾篇文章。
1、部署分佈式集羣
1.1 節點信息
各節點信息如下表所示：
1.2 集羣參數文件
根據實際情況修改集羣參數，或者通過database manager工具生成，內容如下：

GaussDB T分佈式集羣是通過執行gs_upgradectl命令對數據庫版本進行升級的，升級有兩種方式：離線升級和在線滾動升級。對於GaussDB T 1.0.1版本僅支持離線升級，離線升級類型也僅支持離線二進制升級和離線小版本升級兩種類型。對於1.0.2版本的升級，要求升級源版本和升級所使用的目標版本必須同時滿足【升級版本規則】和【升級白名單】時，纔可執行升級操作。
GaussDB T 1.0.1版本僅支持離線升級，需要注意以下事項：（升級前，請嚴格閱讀以下相關注意事項，並確認）
- 集羣內所有節點Python版本要求3.7.2及以上。
- 集羣用戶互信正常。
- 升級前需保證集羣健康狀態正常，所有CN、DN和GTS的狀態正常。
- 僅支持離線升級，離線升級僅支持離線小版本升級和離線二進制升級。
- 僅支持從低版本往高版本升級。
- 離線升級前請停止所有業務，且保證升級過程中沒有任何業務在執行。
- 離線升級前必須確保GTS組和各DN組中主備實例的信息完全同步，且保持升級前長時間穩定同步。
- 升級操作不能和主機替換、擴容、節點替換等其他om側操作同時執行。
- 升級期間不能直接使用cm命令對集羣進行操作，比如switchover等。
- 升級前需要在目標安裝包解壓出的script目錄下執行前置腳本gs_preinstall。
- 離線升級過程中如果已經升級到集羣拉起操作（離線二進制升級）或DN正常拉起操作時（離線小版本升級），則不可執行回滾操作。
- 升級命令中傳入的xml配置文件必須與當前運行集羣的配置結構完全相同。
- 二進制升級後，未執行commit-upgrade進行升級提交的情況下仍可以執行回滾操作，如果驗證確認升級成功後，可以執行commit-upgrade命令以刪除升級臨時文件。
- 小版本升級最後，如果CN和DN均處於READ ONLY模式下，則可以執行回滾；如果CN或主DN處於READ WRITE模式，則不可執行回滾。其中，CN、DN的模式可通過查詢DV_DATABASE的OPEN_STATUS字段獲取。如果驗證確認升級成功，可以執行commit-upgrade命令以刪除升級臨時文件。
- 升級命令執行成功後，如果已執行commit-upgrade命令進行升級提交，則無法再通過調用回滾接口auto-rollback或binary-rollback、systable-rollback回退到老版本。
2.1 安裝python3
另外，GaussDB T 1.0.2要求python版本爲3.7.2及以上，如果系統沒有python3環境，請先安裝配置python3環境再操作。各個集羣節點都要進行安裝操作。

2.8 升級後健康檢查
使用下面的命令對集羣做一次健康檢查，如下：
[omm@hwd08 gaussdb]$ gs_upgradectl -t postcheck -X /mnt/Huawei/db/clusterconfig.xml --upgrade-type=offline-upgrade
Starting check.
Checking cluster health.
Successfully checked cluster health.
Warning: REPL_AUTH is not TRUE for all instances, please use gs_gucZenith tool to set it.
Finished check.
Check result: OK. All check items is normal.2.9 升級失敗後回滾
如果在升級過程中失敗需要回滾，則以omm用戶，執行gs_upgradectl命令回退。如下：
[omm@hwd08 gaussdb]$ gs_upgradectl -t offline-rollback -X /mnt/Huawei/db/clusterconfig.xml
