What would you like to do?
[1] Install
[2] Upgrade
[3] Downgrade
[4] Uninstall
2
What you choose is: Downgrade.
- 输入您想要降级的版本 (升级前的版本)
Which version would you like to downgrade to? (like 22.6.1-1)
22.6.1-1
- 输入您要降级的组件
Edge Admin
Which component would you like to downgrade?
[1] Edge Admin
[2] Edge Admin DB
[3] Rebuild
[4] Edge Node

[6] Log Server DB
1
What you choose is: Edge Admin.
- 输入对应的 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，最后会有如下提示
Great! Downgrade openresty-edge-admin successfully."
2. 回滚 Edge Admin 数据库
- 操作步骤相同，降级时组件选择
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.
- 输入当前的版本
Which version are you currently on? (like 22.6.1)
22.6.1
- 如果成功，最后会有如下提示
Great! update admin database successfully.
3. 重新编译
- 操作步骤相同，降级时组件选择
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.
- 先重新编译几个流量较少的不包含泛域名的 HTTP 应用，再编译几个大流量的不包含泛域名的 HTTP 应用
Do you want to rebuild one application for test? [Y/N]: y
Please input the application id: 1
rebuild application 1
- 再继续根据提示进行编译
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!
如果业务指标都表现正常，升级完成！
如果 HTTP/HTTPS 应用数量很多，可能这一步的编译时间会比较长：
Do you want to rebuild all apps? [Y/N]: y
此时，接下来可以选择并发编译，将启动 4 个进程来编译：
Do you want to compile concurrently? [Y/N]: y
如果不够快，可以修改安装器指定更大的并发，但是不能超过 8，比如：
sudo /bin/bash utils/parallel-recompile.sh 8
4. 回滚 Edge Node
4.1 迁移流量（可选）
为避免影响业务，Edge Node 节点降级前，把该节点上的流量转移到其他未升级节点上。 此步骤为可选，但是强烈建议对最初升级的少数 Edge Node 执行此步骤：
- 迁移走流量
- 升级
- 验证
没问题后，再升级剩下的 Edge Node。另外，升级过程中请关注错误日志。
如果使用的 OpenResty Edge 的 DNS 控制流量，请按以下步骤把即将升级的 Edge Node 节点下线。
- 进入 OpenResty Edge 控制台
- 进入【网关集群】页面
- 对节点所在集群进行【编辑】
- 修改节点【状态】为【关闭 DNS，关闭集群缓存】
- 保存
等待节点不再有流量或只有少量流量。可通过查看访问日志确定：
tail -f /usr/local/oredge-node/logs/access.log
