2.1. 数据库实例启停

本章节将介绍GBase 8s数据库的实例启停方式。数据库安装过程中将实例自动切换成On-Line状态

2.1.1. 数据库实例基本启停操作

2.1.1.1. 检查状态

切换到gbasedbt用户，执行如下命令查看当前实例状态，状态显示为 On-Line

[root@node2 install]# su - gbasedbt
上一次登录：二 6月 18 17:30:52 CST 2024pts/1 上

[gbasedbt@node2 ~]$ onstat -
On-Line -- Up 00:13:17 -- 3378128 Kbytes

2.1.1.2. 关闭实例

执行如下命令关闭GBase 8s数据库服务，状态显示为共享内存未初始化

[gbasedbt@node2 ~]$ onmode -ky

[gbasedbt@node2 ~]$ onstat -
shared memory not initialized for GBASEDBTSERVER 'gbase01'

2.1.1.3. 启动实例

启动数据库服务，最终状态显示为 On-Line

[gbasedbt@node2 ~]$ oninit -y

[gbasedbt@node2 ~]$ onstat -
On-Line -- Up 00:00:15 -- 3378128 Kbytes

注：如需进行正常的数据库操作，请将实例切换至On-Line。

2.1.2. 数据库服务方式启停操作

2.1.2.1. 检查状态

检查服务状态

root@netsky:~# systemctl status GBaseService_gbase01.service

2.1.2.2. 关闭实例

关闭实例

root@netsky:~# systemctl stop GBaseService_gbase01.service

root@netsky:~# systemctl status GBaseService_gbase01.service
○ GBaseService_gbase01.service - GBase 8s Database Server
     Loaded: loaded (/lib/systemd/system/GBaseService_gbase01.service; enabled; vendor preset: enabled)
     Active: inactive (dead)
       Docs: file:/opt/gbase/release/en_us/0333

2.1.2.3. 启动实例

启动实例

root@netsky:~# systemctl start GBaseService_gbase01.service

root@netsky:~# systemctl status GBaseService_gbase01.service
● GBaseService_gbase01.service - GBase 8s Database Server
     Loaded: loaded (/lib/systemd/system/GBaseService_gbase01.service; enabled; vendor preset: enabled)
