环境准备
1 2 3 4 5 6 7 8 9 | docker rm -f gbase8c docker run -itd --name gbase8c -h gbase8c \ -p 5432:5432 \ -v /sys/fs/cgroup:/sys/fs/cgroup \ --privileged=true \ lhrbest/gbase8c:8cV5_S3.0.0B76_1.0 \ /usr/sbin/init docker exec -it gbase8c bash |
数据库启停
启动数据库服务
1 2 3 4 | systemctl start etcd.service su - gbase /home/gbase/gbase_package/script/gha_ctl start all -l http://127.0.0.1:2379 |
停止数据库服务
1 2 3 4 5 6 7 8 9 | su - gbase /home/gbase/gbase_package/script/gha_ctl stop all -l http://127.0.0.1:2379 -- 或 systemctl stop coordinator_gbase_cn1.service systemctl stop datanode_gbase_dn1_1.service systemctl stop gtm_gbase_gtm1.service systemctl stop server_gbase_gha_server1.service systemctl stop etcd.service |
状态检查
执行
1 2 | /home/gbase/gbase_package/script/gha_ctl monitor -l http://127.0.0.1:2379 /home/gbase/gbase_package/script/gha_ctl monitor -l http://127.0.0.1:2379 -H |
结果如下，说明集群安装正常，数据服务启动中

连接和 SQL 测试
在主节点 gbase8c 执行 $ gsql -d postgres -p 5432，出现 postgres=# 操作符说明客户端工具 gsql 成功连接 GBase 8c 数据库。
