oceanbase试用版部署过程：
1.安装包：
mini-ob-deploy.tar --官网提供下载。
2.操作系统和内存（centos6/7、8g内存）
[root@localhost admin]# lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID: CentOS
Description: CentOS Linux release 7.6.1810 (Core)
Release: 7.6.1810
Codename: Core
[root@localhost mini-ob-deploy]# free -g
total used free shared buff/cache available
Mem: 9 3 3 0 2 1
Swap: 3 0 3
[root@localhost mini-ob-deploy]#
3.具体环境：
windows7 + vmware workstation 12.5 上面部署虚拟机centos7.6
4.空间：
配置文件里面默认位置是 “/ob”，所以保证有20G的空闲空间就可以。
5.创建目录
mkdir /ob
chown admin:admin /ob
6.安装mysql客户端
6.1.配置在线yum
cd /etc/yum.repos.d
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
yum clean all
yum makecache
6.2.利用yun安装mysql
rpm -qa | grep mariadb
rpm -e --nodeps mariadb-libs-5.5.35-3.el7.x86_64
rpm -qa|grep -i mysql
yum -y remove mysql-community-client-5.6.38-2.el7.x86_64
cd /usr/local/src
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
service mysqld restart
grep “password” /var/log/mysqld.log
mysql -uroot -p
alter user ‘root’@‘localhost’ identified by ‘scott1!ORACLE’;
SHOW VARIABLES LIKE ‘validate_password%’;
set global validate_password_policy=0;
set global validate_password_length=4;
alter user ‘root’@‘localhost’ identified by ‘oracle’;
flush privileges;
7.用户
userdel -r admin
groupadd admin
useradd -d /home/admin -s /bin/bash -m admin -g admin
passwd admin
8.初始化
cd mini-ob-deploy

9.验证安装
./hap.py ob1.obmysql
执行以下命令查看部署过程中初始化的视图。
show tables;
10.遇到的问题：
10.1./var/log/messages
localhost kernel: traps: observer[2798] trap invalid opcode ip:79a0f8c sp:7fcced1a6340 error:0 in observer[400000+af78000]
搜了一下，是cpu指令集缺失造成，最后也没解决，换了台服务器。
10.2.部署oceanbase会用到mysql客户端 ？
官网文档没说会用到mysql客户端，有些说也可以把mini-ob-deploy中的mysql拷贝到/bin/下面，但是我试了不行，所以我安装了完整的mysql。
