1.现在机器上安装数据库并初始化一个实例(以gbase01为例)
2.配置环境变量
[gbasedbt@localhost ~]$ cp .bash_profile gbase02_profile
[gbasedbt@localhost ~]$ vim gbase02_profile (修改GBASEDBTSERVER为gbase02，与gbase01区分)
3. 配置onconfig文件
[gbasedbt@localhost ~] cp onconfig.gbase01 onconfig.gbase02
[gbasedbt@localhost etc]$ vim onconfig.gbase02
修改参数：
ROOTPATH /data/gbase02/rootchk
PHYSFILE 50000
SERVERNUM 1
DBSERVERNAME gbase02
4. 创建gbase02的rootchk
[gbasedbt@localhost data]$ su - root
密码：
上一次登录：四 4月 14 17:32:43 CST 2022pts/0 上
[root@localhost ~]# cd /data
[root@localhost data]# mkdir gbase02
[root@localhost data]# chown gbasedbt:gbasedbt gbase02
[root@localhost data]# su - gbasedbt
上一次登录：四 4月 14 17:33:26 CST 2022pts/0 上
[gbasedbt@localhost ~]$ cd /data
[gbasedbt@localhost data]$ cd gbase02
[gbasedbt@localhost gbase02]$ touch rootchk
[gbasedbt@localhost gbase02]$ chmod 660 rootchk
[gbasedbt@localhost gbase02]$ ll
总用量 0
-rw-rw----. 1 gbasedbt gbasedbt 0 4月 14 17:51 rootchk
5. 配置sqlhosts文件（追加gbase02监听）
[gbasedbt@localhost etc]$ vim sqlhosts(两个实例的端口号要不一致)
gbase02 onsoctcp 0.0.0.0 9058
gbase01 onsoctcp 172.16.33.199 9088
6. 使环境变量生效
[gbasedbt@localhost ~]$ source gbase02_profile
7. 初始化实例
[gbasedbt@localhost ~]$ oninit –ivy
[gbasedbt@localhost ~]$ onstat -

8. 查看实例情况
[gbasedbt@localhost ~]$ onstat -g dis
