补充:
数据库安装目录:默认路径都是/data/cluster
1.如果没有自定义路径的需求,默认即可
2.如果有自定义cn、dn、etcd、gtm路径安装的需求:
举例:需要把cn_dir路径配置到/data/cn路径下配置修改格式:cn dir=/data/cn
其他路径的自定义路径同上
修改后的install_cluster.conf 配置文件
cd /gaussdb/soft/pkg/GaussDBInstaller/vi install_cluster.conf[COMMON]os_user = ommos_user_group = ${os_user}os_user_home = /home/${os_user}os_user_passwd = Topnet@123root_passwd = Topnet@123ssh_port = 22node_ip_list = 192.168.30.51,192.168.30.52,192.168.30.53[OMAGENT]gauss_home = /gaussdb/clusterom_agent_port = 30170mgr_net =data_net =virtual_net =log_dir = ${gauss_home}/logs/gaussdbcn_dir = ${gauss_home}/data/cngtm_dir = ${gauss_home}/data/gtmcm_dir = ${gauss_home}/data/cmtmp_dir = ${gauss_home}/tempdata_dir = ${gauss_home}/data/dntool_dir = ${gauss_home}/toolsetcd_dir = ${gauss_home}/data/etcd

GaussDB 数据库使用 adaptor接口方式的安装,在adaptor、om-agent安装完成后,会调用 adaptor接口来执行实例的预安装和安装。

实例安装原理
GaussDB 数据库使用 adaptor接口方式的安装,在adaptor、om-agent安装完成后,会调用 adaptor接口来执行实例的预安装和安装。
安装步骤分解
GaussDB管理平台的agent
adaptor接口日志位置:/home/omm/log/adaptor_log
om_agent安装
--安装om-agentpython3 /gaussdb/soft/pkg/GaussDBInstaller/pkgDir/omagent/agent/mgr/install.py,其中,/gaussdb/soft/pkg/GaussDBInstaller路径为om-agent包的解压路径--查看om_agent om_agent.py进程在表示安装成功ps -ef | grep om_agent--日志位置/home/omm/log/om_agent/home/omm/log/om_tmp
预安装、安装
预安装、安装由上层组装json体,通过调用adaptor接口来实现
预安装的目的是在实例安装前完成实例的环境配置,以保证实例安装的正常进行预安装的 adaptor 接口名称为 preinstall,预安装需要在待安装实例的所有节点上以实例用户身份来执行。预安装完成后,就可以进行实例的安装了。实例安装的 adaptor 接口名称为 install,只需以实例用户身份在实例任一个节点上执行即可。
安装日志位置:/gaussdb/soft/pkg/GaussDBInstaller 下的install_cluster.log
