目录
1.下载OceanBase数据库安装包
2. 解压安装包并安装OBD
tar -xzf oceanbase-all-in-one.4.0.0.0-beta-100120221102135736.el7.x86_64.tar.gz
cd oceanbase-all-in-one/bin/
安装obd
./install.sh
设置环境变量
source /root/.oceanbase-all-in-one/bin/env.sh
3.检测OBD是否安装成功
执行 which obd 和 which obclient 检测是否安装成功，如果可以找到 obd 和 obclient 则表示安装
[root@test .obd]# which obd
/root/.oceanbase-all-in-one/obd/usr/bin/obd
[root@test .obd]# which obclient
/root/.oceanbase-all-in-one/obclient/u01/obclient/bin/obclient
4. 启动 OceanBase 数据库
第一种方式：这是官网提供的快速部署启动单实例OceanBase的数据库
（1）部署并启动 OceanBase 数据库
obd demo
（2）使用 OBClient 客户端连接到 OceanBase 数据库
obclient -h127.0.0.1 -uroot -P2881
第二种方式：自定义部署启动单实例OceanBase的数据库
（1）配置文件：oceanbase-jamy.yaml,内容如下
#===================================================
## Only need to configure when remote login is required
# user:
# username: your username
# password: your password if need
# key_file: your ssh-key file path if need
# port: your ssh port, default 22
# timeout: ssh connection timeout (second), default 30
oceanbase-ce:
servers:
# Please don't use hostname, only IP can be supported
- 127.0.0.1
global:
# The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field.
home_path: /root/oceanbase-jamy
# The directory for data storage. The default value is $home_path/store.
# data_dir: /data
# The directory for clog, ilog, and slog. The default value is the same as the data_dir value.
# redo_dir: /redo
# Please set devname as the network adaptor's name whose ip is in the setting of severs.
# if set severs as "127.0.0.1", please set devname as "lo"
# if current ip is 192.168.1.10, and the ip's network adaptor's name is "eth0", please use "eth0"
devname: lo
# External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started.
mysql_port: 2888
# Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started.
rpc_port: 2889
# Defines the zone for an observer. The default value is zone1.
zone: zone1
# The maximum running memory for an observer. When ignored, autodeploy calculates this value based on the current server available resource.
memory_limit: 6G
# The percentage of the maximum available memory to the total memory. This value takes effect only when memory_limit is 0. The default value is 80.
# memory_limit_percentage: 80
# The reserved system memory. system_memory is reserved for general tenants. The default value is 30G. Autodeploy calculates this value based on the current server available resource.
system_memory: 3G
enable_syslog_recycle: true
enable_syslog_wf: false
max_syslog_file_count: 4
production_mode: false
__min_full_resource_pool_memory: 1073741824
cpu_count: 2
datafile_size: 5G
log_disk_size: 5G
# The size of a data file. When ignored, autodeploy calculates this value based on the current server available resource.
# datafile_size: 200G
# The size of disk space used by the clog files. When ignored, autodeploy calculates this value based on the current server available resource.
# log_disk_size: 66G
# System log level. The default value is WDIAG.
# syslog_level: WDIAG
# Print system logs whose levels are higher than WARNING to a separate log file. The default value is true. The default value for autodeploy mode is false.
# enable_syslog_wf: false
# Enable auto system log recycling or not. The default value is false. The default value for autodeploy mode is on.
# enable_syslog_recycle: true
# The maximum number of reserved log files before enabling auto recycling. When set to 0, no logs are deleted. The default value for autodeploy mode is 4.
# max_syslog_file_count: 4
# Cluster name for OceanBase Database. The default value is obcluster. When you deploy OceanBase Database and obproxy, this value must be the same as the cluster_name for obproxy.
#appname: obcluster
# Password for root. The default value is empty.
#root_password:
# Password for proxyro. proxyro_password must be the same as observer_sys_password. The default value is empty.
# proxyro_password:
#===================================================
注意：你的磁盘大小需要大于memory_limit+system_memory+__min_full_resource_pool_memory+datafile_size+log_disk_size的总和，这里就是要大于20G（6G+3G+1G+5G+5G），还有一点要注意的是memory_limit的大小会决定OceanBase数据库能否成功启动，我这里虚拟机linux的内存大小给的是10G,除去系统本身用去的内存，实际可用的的内存就没有10G了，我第一次启动就失败了，截图如下：报了一个内存不够的报错提示，所以我把配置文件中memory_limit的值调整为6G,最后启动成功！！！
（2）部署
obd cluster deploy 集群名 -c yaml部署文件路径
例如：
obd cluster deploy oceanbase-jamy -c /opt/oceanbase-all-in-one/conf/autodeploy/oceanbase-jamy.yaml
（3）启动数据库
obd cluster start oceanbase-jamy
（4）连接数据库
obclient -h127.0.0.1 -uroot@sys -P2888
自定义部署启动过程如下所示：
[root@localhost ~]# obd cluster deploy oceanbase-jamy -c /opt/oceanbase-all-in-one/conf/autodeploy/oceanbase-jamy.yaml

5. 登录OceanBase 数据库
本地登录（刚安装完登录root用户默认密码为空即直接回车即可连接上数据库，但是新版不是为空，但是会直接在命令行启动窗口给提示临时登录密码是多少）
obclient -h127.0.0.1 -uroot -P2881
创建数据库
create database test2 default charset utf8mb4;
创建用户
create user jamy@'%' identified by '123456';
修改用户密码
alter user jamy@'%' identified by 'jamy';
授权用户
grant all privileges on *.* to jamy@'%';
6. 客户端连接
（1）navicat连接OceanBase
能连mysql的客户端都可以连接OceanBase,只不过端口号需要换成2881
（2）SQLyog连接OceanBase
（3）heidisql连接OceanBase
（4）OceanBase Developer Center连接OceanBase
odc客户端是OceanBase官方图形化客户端

9.部署ODC的web端服务(docker容器部署)
这里部署ODC的web端服务是使用官网推荐的docker镜像启动docker容器（web容器）
（1）安装docker
docker安装参考这里教程，根据自己Linux的版本选择性安装
（2）拉取odc的docker镜像
docker pull oceanbase/odc:4.2.2
（3）创建挂载目录
mkdir -p /var/log/odc /var/data/odc
（4）启动容器
docker run -v /var/log/odc:/opt/odc/log -v /var/data/odc:/opt/odc/data \
-d -i --net host --cpu-period 100000 --cpu-quota 400000 --memory 6G --name "obodc" \
-e "DATABASE_HOST=192.168.225.49" \
-e "DATABASE_PORT=2888" \
-e "DATABASE_USERNAME=jamy@sys" \
-e "DATABASE_PASSWORD=123456" \
-e "DATABASE_NAME=odc_oceanbase" \
-e "ODC_PROFILE_MODE=alipay" \
-e "ODC_ADMIN_INITIAL_PASSWORD=ACbc214325%#@" \
oceanbase/odc:4.2.2
说明：
–net host 共享宿主机的网络
–memory 设置docker容器内存的最大使用内存（根据你内存大小的实际情况，但是不能太小）
DATABASE_HOST 设置你的Oeacanbase数据库的IP地址
DATABASE_PORT 设置你的Oeacanbase数据库的端口号
DATABASE_USERNAME 设置你的Oeacanbase数据库的用户（格式是 用户名@租户名#集群名）
DATABASE_PASSWORD 设置你的Oeacanbase数据库的用户密码（这里就是用户jamy的密码）
DATABASE_NAME 设置ODC的web端连接的Oeacanbase数据库名，如果该数据库不存在，需要先创建
ODC_PROFILE_MODE 默认为alipay
ODC_ADMIN_INITIAL_PASSWORD 这个就是你首次访问ODC的web端的登录密码，登录用户名默认为admin
（）访问ODC的web版
这里搭建的ODC的web版非常适用于团队使用，只要登录浏览器就可以访问，启动容器显示如下，表示服务搭建成功
访问地址：http://容器所在的宿主机:8989
团队空间
个人空间
选择表查看表结构
选择表查看表数据
打开sql查询窗口
10.部署ODC的web端服务(直接在linux下部署)
ODC的web客户端是使用Java编写的，所以需要在Linux安装jdk,版本为1.8
（1）配置环境变量
vim /etc/profile,在文件末尾添加如下内容后执行source /etc/profie使得新的环境变量生效
export ODC_JVM_TRY_USE_JDK=1
export ODC_ADMIN_INITIAL_PASSWORD=ACbc214325%#@
export ODC_PROFILE_MODE=alipay
export DATABASE_PORT=2888
export DATABASE_NAME=odc_oceanbase
export DATABASE_USERNAME=jamy@sys
export DATABASE_HOST=192.168.225.49
export DATABASE_PASSWORD=123456
export OLDPWD=/opt/odc
（2）创建数据库
在连接的数据库创建odc_oceanbase,建库语句如下：
CREATE DATABASE odc_oceanbase DEFAULT CHARSET utf8mb4;
（3）将odc-web.zip压缩包解压到/opt目录下即可（odc-web.zip如果有需要可以@我）
（4）启动odc,执行如下命令
cd /opt/odc/bin/
sh start-odc.sh (直接在当前窗口运行，窗口关了，odc也就停止运行了)
或者
sh nohup-start-odc.sh (后台运行，适合长期运行服务)
如何确定启动是否成功
一是执行命令ps -ef|grep java查看服务进程
二是查看日志
tail -10f /opt/odc/log/odc.log
注意：odc使用java编写，所以必须安装jdk才能使用，openjdk也可以，版本是1.8
（5）连接web客户端
登录地址：http://部署odc的Linux的IP地址:端口号,端口号也是可以在环境变量里设置的，默认是8989，我这里的访问地址是192.168.225.68:8989,
登录用户是admin
密码就是（1）中设置的ACbc214325%#@，密码设置规则如下，这是设置的密码不符合密码规则的提示,登录成功后可以修改，但也要符合密码约束规则，下面有一个修改的截图
登录进去具体操作大家可以自己研究研究，这里不做过多讲述。
Bean create failed, beanName=odcServer, message=Error creating bean with name 'odcServer': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'metadbMigrate': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Illegal password, please check your password,
a valid password should:
1. has length between 8~32;
2. contains at least 2 number;
3. contains at least 2 alpha;
4. contains at least 2 special character(._+@#$%);
