练习目的
本次练习目的掌握 OceanBase 集群的自动化部署（OBD工具）技术，能自动部署OB集群，包含 OBProxy，以及部署 OBAgent 等。
练习条件
- 有 服务器，内存资源至少
12G*3台 或者32G*1台
练习内容
请记录并分享下列内容：
- （必选）部署 OBD 软件，离线或者在线都可以。
- （必选）使用 OBD 部署一套三副本集群（单机3节点或者3节点都可以），部署至少1个 OBProxy。
- （必选）部署至少一个 OBAgent 。
- （可选）部署 Promethues ，能查看采集的 OB 性能或状态数据。
- （可选）部署 Grafana，能使用 OB 的性能模板查看 OB性能数据。
环境规划
环境是这样的，只有一台虚拟机，配置16c80G，准备使用docker来模拟出4台CentOS主机，搭建OceanBase 3.1.1社区版的集群。OBServer每台至少需要8G内存，否则不能启动。
具体配置如下所示：
| 主机名 | IP | 端口 | 主机映射端口 | Zone | 作用 |
|---|---|---|---|---|---|
| lhrob1 | 172.72.8.11 | 2881 | 28811 | zone1 | OB Server1、OBAgent |
| lhrob2 | 172.72.8.12 | 2881 | 28812 | zone2 | OB Server2、OBAgent |
| lhrob3 | 172.72.8.13 | 2881 | 28813 | zone3 | OB Server3、OBAgent |
| lhrobproxy | 172.72.8.14 | 2883 | 28814 | 用于OBD、OBProxy、OBClient、mysql、Promethues、Grafana、OB客户端、时间服务器等 |
OBAgent是OceanBase社区版数据库服务监控组件。
OBD 全称是 OceanBase Deployer，是 OceanBase 社区版的命令行下自动化部署软件。
ODP：OceanBase 数据库代理，简称为 ODP。ODP 是 OceanBase 数据库专用的连接代理软件。ODP 的核心功能包括：保证最佳路由，避免分布式事务；保护 OceanBase 数据库的高可用能力，单台服务器故障不影响应用。

配置时钟源
如果您使用集群安装 OceanBase，则需要保证集群内各机器的时间同步。否则集群无法启动，服务在运行时也会出现异常。如果您已配置 NTP 时钟同步，则无需重新配置。
OceanBase 集群中的服务器时间必须保持一致，否则会导致 OceanBase 集群无法启动，运行时也会出现故障。物理机与时钟服务器的误差在 50ms 以下可认为时钟是同步状态，OceanBase 集群最大容忍误差不能超过 100ms。当超过 100ms 时，会出现无主情况。恢复时钟同步后。重启 OceanBase 集群, 可以恢复正常。
部署 OceanBase 集群时，各个 OBServer 的 RPC 允许的时钟偏差最大是100ms。
这里以“172.72.8.14”为时间服务器，其它3台OBServer同步该机器的时间：
1 2 3 4 | yum install ntp ntpdate -y ntpq -4p ntpstat timedatectl |
1、修改“172.72.8.14”为时间服务器/etc/ntp.conf
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 | # For more information about this file, see the man pages # ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5). driftfile /var/lib/ntp/drift #新增:日志目录 logfile /var/log/ntpd.log # Permit time synchronization with our time source, but do not # permit the source to query or modify the service on this system. restrict default nomodify notrap nopeer noquery # Permit all access over the loopback interface.

配置开机启动：
1 2 3 4 5 6 7 8 9 10 | systemctl enable ntpd systemctl is-enabled ntpd ntpdate -u 1.cn.pool.ntp.org systemctl restart ntpd [root@lhrobproxy /]# ntpstat synchronised to NTP server (84.16.73.33) at stratum 2 time correct to within 98 ms polling server every 64 s |
其它客户端，修改“/etc/ntp.conf”，注释server开头的行，并添加如下行：
1 2 3 4 5 6 7 | server 172.72.8.14 restrict 172.72.8.14 nomodify notrap noquery server 127.0.0.1 fudge 127.0.0.1 stratum 10 |
配置开机启动：
1 2 | systemctl enable ntpd systemctl restart ntpd |
客户端配置自动同步：
1 2 | crontab -e * * * * * /usr/sbin/ntpdate -u 172.72.8.14 & > /dev/null |
检查：
- 机器三节点之间时间同步检查,检查本机和目标节点时间误差常用命令是：
clockdiff。
1 2 3 4 5 6 7 8 9 | [root@lhrobproxy soft]# clockdiff lhrob1 .. host=lhrob1 rtt=562(280)ms/0ms delta=0ms/0ms Sun Jan 9 10:39:43 2022 [root@lhrobproxy soft]# clockdiff lhrob2 . host=lhrob2 rtt=750(187)ms/0ms delta=0ms/0ms Sun Jan 9 10:39:57 2022 [root@lhrobproxy soft]# clockdiff lhrob3 . host=lhrob3 rtt=750(187)ms/0ms delta=0ms/0ms Sun Jan 9 10:40:00 2022 |

delta = 目标主机减当前主机时间 ,时间单位是毫秒。
三节点时间同步误差如果超过 50ms，则后面初始化集群一定会失败。 这里还要留意节点的时间误差可能有个缓慢递增的特点，也许当前集群还能正常工作，一天后由于节点时间误差扩大到 50ms 以外，该节点就掉线了。
配置内核参数
4个节点都运行：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | cat >> /etc/security/limits.conf <<"EOF" root soft nofile 655350 root hard nofile 655350 * soft nofile 655350 * hard nofile 655350 * soft stack 20480 * hard stack 20480 * soft nproc 655360 * hard nproc 655360 * soft core unlimited * hard core unlimited EOF echo "fs.aio-max-nr=1048576" >> /etc/sysctl.conf sysctl -p |
如果只是测试，您可以只设置 fs.aio-max-nr=1048576。
创建用户
1 2 3 4 5 6 7 | useradd -U admin -d /home/admin -s /bin/bash echo "admin:lhr" | chpasswd chown -R admin:admin /home/admin echo "admin ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers |
设置无密码SSH登陆
可以使用rac上的sshUserSetup.sh快速配置，只在lhrobproxy上运行：
1 | sh sshUserSetup.sh -user admin -hosts "lhrob1 lhrob2 lhrob3 lhrobproxy" -advanced exverify -confirm |
安装集群
在lhrobproxy操作：
安装OBD
1 2 3 | yum install -y yum-utils yum-config-manager --add-repo https://mirrors.aliyun.com/oceanbase/OceanBase.repo yum install -y ob-deploy |
设置yaml的配置文件
OBD 针对不同的部署场景提供不同的配置文件。这些配置文件示例在 OceanBase 开源项目地址里，具体是：https://github.com/oceanbase/obdeploy/tree/master/example 。
OBD根据这个yaml文件即可自动创建集群。
