巨杉SequoiaDB 5.0.1日常运维使用命令汇总

本文介绍巨杉SequoiaDB 5.0.1,日常运维和使用的命令,包括启动,停止,查看版本,服务状态等。包括操作系统命令和数据库 shell 命令两大类。

集群shell可以启停所有同组节点的服务,而操作系统命令的只能启停当前节点的。如果节点较多,还是用集群的shell更简单。

测试发现,通过sheel必须协调和编目服务都正常时才可以。否则报-104 Node is not primary的错误。

如果你通过sdb将协调节点组停止后,需通过操作系统命令启动后才能进行数据库 shell 命令操作。

操作系统命令查看巨杉SequoiaDB的版本

先切换用户到数据库用户, 比如sdbadmin

[root@gbase_rh7_001 ~]# su - sdbadmin

[sdbadmin@gbase_rh7_001 ~]$ sequoiadb --version
SequoiaDB version: 5.0.1
Release: 39282
Git version: 49d120b9724b64c8420df002093c6c8414402449
2020-10-16-15.09.14

操作系统命令查看存储引擎节点列表

无服务运行时,显示空。

[sdbadmin@gbase_rh7_001 ~]$ sdblist
Total: 0
[sdbadmin@gbase_rh7_001 ~]$ 

有服务运行时,结果如下。

[sdbadmin@gbase_rh7_001 ~]$ sdblist
sequoiadb(11800) (3574) C
sequoiadb(11820) (3577) D
sequoiadb(11810) (3580) S
Total: 3
[sdbadmin@gbase_rh7_001 ~]$

其中 S表示协调服务(?),D表示数据服务(Data),C表示编目服务(Catalog/Schema)

长格式,显示更详细的信息:包括PID服务启动时间,路径,分组名字等。

[sdbadmin@gbase_rh7_001 ~]$ sdblist -l
