使用 ANTMAN 工具替换 OceanBase 云平台节点

OceanBase 环境基本都会先安装 OCP 来部署、监控、运维数据库集群。但如果有机器过保等问题,就需要有平稳的 OCP 节点的替换方案。

前言

OceanBase 云平台(OceanBase Cloud Platform,OCP),是以 OceanBase 为核心的企业级数据库管理平台。

我们生产环境基本都是需要先创建 OCP 平台,然后依赖 OCP 去创建及管理监控生产集群,所以安装 OCP 一般是系统上线的第一步。之后可能随着机房规划等问题,就会有需要搬迁或者替换 OCP 的机器的需求。

分别介绍两种 OCP 节点的替换方法。一种是使用 OAT 平台(OceanBase Admin Toolkit,管理者工具)来替换;另一种就是使用 ANTMAN 工具替换。上次我们介绍了第一种 OAT 的方案,本文介绍第二种。

PS:我的环境的 OCP 负载均衡使用的 F5,所以新的机器需要先配置 F5,其他负载均衡场景同理。

环境背景

大家如果有接触 OB 生产环境的经验的话,可能会了解,前期版本在安装 OCP 的时候,需要安装 OCP 软件/metadb/obproxy 三个 Docker 包,后期 OCP 版本将 DB+Proxy 集成在了一个 Docker 包里,OAT 的话只能纳管 DB + Proxy。集成的 metadb,分开的情况还需要使用 ANTMAN 工具来替换。

软件信息

软件 版本
OCP ocp-all-in-one:3.3.3-20220906114643
metadb+proxy OB2277_OBP320_x86_20220429
Proxy 4.1.1_20230519_x86
antman t-oceanbase-antman-1.4.3-20220807073355.alios7.x86_64

操作过程

3.1 环境检查/准备

检查替换机器环境,包括分盘,创建 admin 用户,安装 Docker 软件等。安装好后检查下。

cd /root/t-oceanbase-antman/clonescripts/
sh precheck.sh -m ocp

登录 meta 库检查有没有 tenant 的主 ZONE 在要被替换的节点,提前切主。

因为使用 ANTMAN 工具迁移,需要在执行机器上修改 obcluster.conf 文件,或者直接从原 OCP 上 copy 后检查下,镜像包也需要传到该机器 /root/t-oceanbase-antman 目录下。

55obffocp:~/t-oceanbase-antman # cat obcluster.conf

检查执行 ANTMAN 脚本机器上默认集群密码是否正确。cd ~/t-oceanbase-antman/tools,执行 getpass.sh 的脚本,如果不对需要使用 setpass.sh 修改,因为后续 Proxy 的 Docker 迁移后会有验证,OCP 的 Docker 迁移前也会验证。

执行 ANTMAN 的 manage 脚本进行新机器的添加。

PS:这个版本 manage 会有报错,文末会有分享。

这里日志太多,就不都粘贴出来了,可以从上面看到 metadb 的 Docker 服务添加完后开始了 OBProxy 的 Docker 服务添加。

过程说明

  1. 133.55.22.19 是要去替换 OCP 的服务器的实际物理 IP。
  2. -z 1 选项,指定的 133.55.22.19 会被添加到 OCP 环境中的第 1 个 ZONE,即和上文查到的 10.10.100.9 机器在同一个 ZONE 里。

    这里关于 ZONE 的定义,主要是针对 OCP 服务器上的 meta_ob docker 而言,obproxy dockerocp docker 并没有 ZONE 的概念。

    关于每台 OCP 服务器上的 meta_ob docker 属于哪一个 ZONE,请参考 obcluster.conf 配置文件中的三个变量:

    • ZONE1_RS_IP
    • ZONE2_RS_IP
    • ZONE3_RS_IP
  3. -R-A,后面需要分别填写成 133.55.22.19 服务器的 root 用户密码和 admin 用户密码。
  4. -i 是安装,如果替换成 -c 就是清除。

这时候正常的话可以通过新添加节点的 IP:8080 前台登录 OCP,也可以通过这个机器的 2883 端口去连 meta 库了。

3.3 新增租户

登录 OCP 的 metadb 的 sys 租户新增 meta_ob Docker 的上线。

3.5 更新服务器信息

登录 ocp_meta 租户,手工更新 OCP 服务器信息。

总结

到此,使用 ANTMAN 工具的方式去替换 OCP 机器的操作就结束了,包括前面一篇使用 OAT 替换 OCP 节点的文章可能看起来没什么难度,但是整个过程来回做了好几遍,充满我的坎坷和泪水。为了别人以后少踩坑,所以写了这两篇文章分享。

如果看了上篇文章的话,应该知道 OAT 替换 OCP 的时候,新加机器是在 metadb 中新创建了一个 ZONE,然后再把被替换机器下掉。其中还涉及新建资源池修改 Locality,增加副本数等操作。其实使用 ANTMAN 工具的话这个步骤就不太一样,是将新机器加入到需要替换机器的同一个 ZONE 内,然后做同 ZONE 内 UNIT 的迁移,然后把被替换的机器下线。

现阶段的话,相对来说使用 ANTMAN 工具替换之后对于 OCP 元数据的影响更小一些,但是 OAT 黑屏操作更少已些。对于 OBProxy 单独 Docker 的前期场景必须使用 ANTMAN,后期版本就看大家自己酌情选择了。

行之所向,莫问远方。
