注意:PTK工具本身可以在多种操作系统中运行,支持Linux,macOS,Windows,但是由于 MogDB 目前仅支持在Linux 系统中运行,因此需确保要运行MogDB数据库的服务器为 Linux 操作系统。
安装准备
有关环境要求和操作系统配置详情,请参见环境要求和操作系统配置。
下载安装 PTK
有关PTK安装,请访问安装PTK。
通过PTK安装MogDB
准备拓扑配置文件
PTK安装需要用户提供配置文件config.yaml,PTK支持单节点安装以及多节点安装。下面以单节点安装和一主一备节点安装为例。
单节点安装
# config.yaml
global:
cluster_name: mogdb1
user: omm
group: omm
base_dir: /opt/mogdb
db_servers:
- host: 127.0.0.1
db_port: 26000
如果全部使用默认值,则PTK 执行以下操作:
- 在本机安装数据库;
- 运行数据库的操作系统用户为omm ,用户组名称也是omm,该用户没有默认密码;
- 数据库安装在 /opt/mogdb目录下,在该目录下会创建4个目录:app, data, log, tool,分别用于存储数据库软件、数据文件、数据库日志和数据库相关工具;
- 数据库监听端口为26000;
主备节点安装
# config.yaml
global:
cluster_name: mogdb_cluster1
user: omm
group: omm
base_dir: /opt/mogdb
db_servers:
- host: 192.168.0.1
db_port: 26000
role: primary
ssh_option:
port: 22
user: root
password: [此处填写SSH登录密码,密码需要通过 ptk encrypt 加密后填写]
- host: 192.168.0.2
db_port: 26000
role: standby
ssh_option:
port: 22
user: root
password: [此处填写SSH登录密码,密码需要通过 ptk encrypt 加密后填写]
检查本机系统
ptk checkos -f config.yaml
确保输出的检查结果均为 OK
或者 Warning
,如果有 Abnormal
或 ExecuteError
出现,需用户根据日志提示先修正系统参数。
如果有 Abnormal
检查项,ptk 会自动生成一个 root_fix_***.sh 文件,可用于快速修正系统参数;如果有 ExecuteError
检查项,代表 ptk 执行失败,需要用户根据错误信息调整系统环境。
执行安装
ptk install -f config.yaml
默认会安装当前已经正式发布的 MogDB 最新版本,版本号可以在 MogDB 官网下载页面查询。安装过程中会提示用户输入数据库初始用户的密码,请用户自行记录并安全保存。PTK 自动完成所有安装操作后,会启动数据库实例。
PTK 也支持自定义安装包,可以通过手工下载安装包,指定安装。例如执行以下命令,将使用当前目录下的该安装包进行数据库安装。
ptk install -f config.yaml --pkg ./MogDB-3.1.0-openEuler-arm64.tar.gz
安装成功后,可以通过 ptk ls
来查看安装的实例信息。
[root@hostname]# ptk ls
cluster_name | instances | user | data_dir | db_version
---------------+--------------------+------+-----------------+--------------
mogdb1 | 172.16.0.127:26000 | omm | /opt/mogdb/data | MogDB-3.1.0
访问数据库
su - omm
gsql -d postgres -p 26000
通过PTK卸载MogDB
注意:数据库卸载后无法恢复,请谨慎操作。
执行如下命令卸载数据库:
ptk uninstall (-f CONFIG.YAML|--name CLUSTER_NAME)
在卸载前,PTK 会交互式的询问用户,以确认要删除的数据库信息,确认是否要连带删除系统用户,以及确认是否要连带删除数据库数据。请在回答每一个问题时,确认你的回答,避免由于误操作导致不可恢复的数据丢失!
在 PTK 执行数据库卸载操作时,如果用户指定了删除数据目录,PTK 仅会删除数据目录,不会删除数据目录所在的父目录,需用户手动清理父目录。
卸载成功后,将提示如下信息:
[root@hostname]# ptk uninstall -n mogdb1

注意:使用配置文件来卸载的前提是配置文件还存在。使用集群名称来指定的前提是
ptk ls
可以正常查询到该集群。
