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 |
lhrob2 | 172.72.8.12 | 2881 | 28812 | zone2 | OB Server2 |
lhrob3 | 172.72.8.13 | 2881 | 28813 | zone3 | OB Server3 |
lhrobproxy | 172.72.8.14 | 2883 | 28814 | 用于OBD、OBProxy、OBClient、mysql客户端、时间服务器等 |
初始化准备
申请环境
代码语言：javascript复制docker network create --subnet=172.72.8.0/16 lhrob-network
docker network inspect lhrob-network
docker rm -f lhrob1 lhrob2 lhrob3 lhrobproxy
docker run -d --name lhrob1 -h lhrob1
--net=lhrob-network --ip 172.72.8.11
-p 28811:2881

docker exec -it lhrobproxy bash
配置时钟源
参考：https://open.oceanbase.com/docs/community/oceanbase-database/V3.1.1/optional-configuring-clock-sources
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：
代码语言：javascript复制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
代码语言：javascript复制# 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. This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1
restrict ::1
#新增:这一行的含义是授权172.72.8.0网段上的所有机器可以从这台机器上查询和同步时间.
restrict 172.72.8.0 mask 255.255.255.0 nomodify notrap
# Hosts on local network are less restricted.
#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
# Use public servers from the pool.ntp.org project.

#server 2.centos.pool.ntp.org iburst

disable monitor
配置开机启动：
代码语言：javascript复制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：
代码语言：javascript复制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：
代码语言：javascript复制systemctl enable ntpd
systemctl restart ntpd
客户端配置自动同步：
代码语言：javascript复制crontab -e
* * * * * /usr/sbin/ntpdate -u 172.72.8.14 & > /dev/null
配置内核参数
4个节点都运行：
代码语言：javascript复制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
代码语言：javascript复制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：
代码语言：javascript复制sh sshUserSetup.sh -user admin -hosts "lhrob1 lhrob2 lhrob3 lhrobproxy" -advanced exverify -confirm
安装集群
在lhrobproxy操作：
安装OBD
代码语言：javascript复制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根据这个yaml文件即可自动创建集群
代码语言：javascript复制cat > /tmp/obd_observer_obproxy.yaml <<"EOF"

obproxy跟OB集群通信是使用sys租户内的一个内部账户proxyro。这个账户需要创建。
obproxy启动后，默认用 root@proxysys 登录，密码为空。需要改密码（通过proxy参数obproxy_sys_password指定）。
obproxy启动后，还需要修改proxyro的密码（通过proxy参数observer_sys_password指定），设置为跟OB集群里创建的proxyro密码一致才能链接那个OB集群。
