降級 OpenResty Edge
注意
如升級失敗，可執行以下步驟進行回滾，操作前請與 OpenResty Inc. 的同事約定時間。1. 回滾 Edge Admin
- 下載安裝器
curl -O https://openresty.com/client/oredge/openresty-edge-installer.sh
- 執行安裝器
sudo /bin/bash openresty-edge-installer.sh
- 輸入您要執行的操作
Downgrade
What would you like to do?
[1] Install
[2] Upgrade
[3] Downgrade
[4] Uninstall
2
What you choose is: Downgrade.
- 輸入您想要降級的版本 (升級前的版本)
Which version would you like to downgrade to? (like 22.6.1-1)
22.6.1-1
- 輸入您要降級的元件
Edge Admin
Which component would you like to downgrade?
[1] Edge Admin
[2] Edge Admin DB
[3] Rebuild
[4] Edge Node
[5] Log Server
[6] Log Server DB
1
What you choose is: Edge Admin.
- 輸入對應的 openresty-plus 版本
Which version of openresty-plus would you like to downgrade to? (like 1.19.9.1.3-1)
1.19.9.1.15-1
- 如果成功，最後會有如下提示
Great! Downgrade openresty-edge-admin successfully."
2. 回滾 Edge Admin 資料庫
- 操作步驟相同，降級時元件選擇
Edge Admin DB
Which component would you like to downgrade?
[1] Edge Admin
[2] Edge Admin DB
[3] Rebuild
[4] Edge Node
[5] Log Server
[6] Log Server DB
2
What you choose is: Edge Admin DB.
- 輸入當前的版本
Which version are you currently on? (like 22.6.1)
22.6.1
- 如果成功，最後會有如下提示
Great! update admin database successfully.
3. 重新編譯
- 操作步驟相同，降級時元件選擇
Rebuild
Which component would you like to downgrade?
[1] Edge Admin
[2] Edge Admin DB
[3] Rebuild
[4] Edge Node
[5] Log Server
[6] Log Server DB
3
What you choose is: Rebuild.
- 先重新編譯幾個流量較少的不包含泛域名的 HTTP 應用, 再編譯幾個大流量的不包含泛域名的 HTTP 應用
Do you want to rebuild one application for test? [Y/N]: y
Please input the application id: 1
rebuild application 1
- 再繼續根據提示進行編譯
Do you want to rebuild upgrade config? [Y/N]: y
rebuild upgrade config
recompile upgrade configurations successfully
Do you want to rebuild all wilecard apps? [Y/N]: y
rebuild all wilecard apps
Do you want to rebuild all apps? [Y/N]: y
Do you want to compile concurrently? [Y/N]: n
rebuild all apps
Do you want to rebuild all http_proxy apps? [Y/N]: y
rebuild all http_proxy apps
Do you want to rebuild all socks5_apps? [Y/N]: y
rebuild all sock5_proxy apps
Do you want to rebuild global? [Y/N]: y
rebuild global
recompile global successfully
Do you want to rebuild waf? [Y/N]: y
rebuild waf
recompiled all of the WAF rule sets successfully.
Do you want to rebuild dns? [Y/N]: y
rebuild dns
recompile dns successfully.
Do you want to rebuild global-action? [Y/N]: y
rebuild global-action
recompile global action successfully
Do you want to rebuild gateway? [Y/N]: y
rebuild gateway
recompiled gateway successfully
rebuild done!
如果業務指標都表現正常，升級完成！
如果 HTTP/HTTPS 應用數量很多，可能這一步的編譯時間會比較長：
Do you want to rebuild all apps? [Y/N]: y
此時，接下來可以選擇併發編譯，將啟動 4 個程序來編譯：
Do you want to compile concurrently? [Y/N]: y
如果不夠快，可以修改安裝器指定更大的併發，但是不能超過 8，比如：
sudo /bin/bash utils/parallel-recompile.sh 8
4. 回滾 Edge Node
4.1 遷移流量（可選）
為避免影響業務，Edge Node 節點降級前，把該節點上的流量轉移到其他未升級節點上。 此步驟為可選，但是強烈建議對最初升級的少數 Edge Node 執行此步驟：
- 遷移走流量
- 升級
- 驗證
沒問題後，再升級剩下的 Edge Node 。另外，升級過程中請關注錯誤日誌。
如果使用的 OpenResty Edge 的 DNS 控制流量，請按以下步驟把即將升級的 Edge Node 節點下線。
- 進入 OpenResty Edge 控制檯
- 進入【閘道器叢集】頁面
- 對節點所在叢集進行【編輯】
- 修改節點【狀態】為【關閉 DNS，關閉叢集快取】
- 儲存
等待節點不再有流量或只有少量流量。可透過檢視訪問日誌確定：
tail -f /usr/local/oredge-node/logs/access.log
