通过OBD部署OB-4.0.0集群、并使用OCP接管OB集群操作步骤

专栏投稿
#1

最近有使用OB新做一个大数据实时数仓OLAP分析的需求，以往都是用手动方式离线部署的集群。本次使用OBD进行部署，花个周末总结一下OBD及OCP的搭建过程，对于第一次部署弯路还是挺多的，感谢苏琅老师和李作群老师，没有您们孜孜不倦的指导，就没有这篇文章。

OBD 全称为 OceanBase Deployer，是 OceanBase 开源软件的安装部署工具。OBD 同时也是包管理器，可以用来管理 OceanBase 所有的开源软件。

1.主机准备

主机配置

ip 主机名 CPU 内存 硬盘 计划部署应用
192.168.18.18 node18 24核心 64G 500G OBD、OBServer、OBProxy、OCP
192.168.28.44 cmagent44 24核心 64G 500G OBServer
192.168.28.53 node53 24核心 64G 500G OBServer

硬盘配置

文件系统        容量  已用  可用 已用% 挂载点
devtmpfs         32G     0   32G    0% /dev
tmpfs            32G   44K   32G    1% /dev/shm
tmpfs            32G  1.2M   32G    1% /run
tmpfs            32G     0   32G    0% /sys/fs/cgroup
/dev/sda2        40G   17G   21G   46% /
/dev/sda1       477M  145M  304M   33% /boot
/dev/sda4       502G  7.3G  470G    2% /data
cm_processes     32G  576K   32G    1% /run/cloudera-scm-agent/process

2.用户准备

创建admin用户：

# 创建用户（/data目录可用空间大）
[root@node18 ~]$ useradd -d /data/home/admin admin -m
# 制作软连接，否则OCP部署目录上有问题
[root@node18 ~]$ ln -s /data/home/admin /home/admin
# 给 admin 用户添加 sudo 权限，用于OBD部署集群，且OCP会检查该项
[root@node18 ~]$ chmod u+w /etc/sudoers
[root@node18 ~]$ echo 'admin ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
[root@node18 ~]$ chmod u-w /etc/sudoers
# 自免密码登录制作，用于OBD部署集群
[root@node18 ~]$ su - admin
[admin@node18 ~]$ ssh-keygen -t rsa 
[admin@node18 ~]$ cp   ~/.ssh/id_rsa.pub   ~/.ssh/authorized_keys

SSH密匙制作及配置

可使用xshell制作密匙对，应对密码无法登录的生产环境，用于OCP管理集群

# 私钥 用于填写在OCP中
-----BEGIN RSA PRIVATE KEY-----
MIIEoQIBAA....省略2048....BNk7sQ==
-----END RSA PRIVATE KEY-----
# 公钥 放在主机上
ssh-rsa AAAAB3NzaC1....省略....P4fCfow== rsa 2048-021123

制作完毕后，所有机器/data/home/admin/.ssh/authorized_keys文件内容如下

3.部署OBD

在192.168.18.18主机上部署obd

[admin@node18 ~]$ sudo yum install -y yum-utils
[admin@node18 ~]$ sudo yum-config-manager --add-repo https://mirrors.aliyun.com/oceanbase/OceanBase.repo
[admin@node18 ~]$ sudo yum install -y ob-deploy
# 使用模板部署
[admin@node18 ~]$ cp /usr/obd/example/mini-distributed-with-obproxy-example.yaml .
# 编辑配置文件
[admin@node18 ~]$ vim ~/mini-distributed-with-obproxy-example.yaml

部署配置文件内容如下：

其中密码是必填的，是OCP部署的检查项，注意proxyro_password和observer_sys_password值是相同的

## Only need to configure when remote login is required

   username: admin

开始部署：

# 如有部署失败，铲除原有部署
[admin@node18 ~]$ obd cluster stop obcluster
[admin@node18 ~]$ obd cluster destroy obcluster
[admin@node18 ~]$ rm -rf /data/home/admin/.obd/
# 开始部署
[admin@node18 ~]$ obd cluster deploy obcluster -c  ~/mini-distributed-with-obproxy-example.yaml
[admin@node18 ~]$ obd cluster start obcluster
# 如obproxy健康检查失败，再启动一次可解决健康检查失败，健康检查失败集群未进入running状态将影响OCP部署前健康检查。
[admin@node18 ~]$ obd cluster start obcluster
# 如需调整内存、cpu、硬盘等参数，可通过以下命令进行调整参数，根据返回的提示进行重启或重载的操作
[admin@node18 ~]$ obd cluster edit-config obcluster
