2.操作系统不限,能安装 Docker 环境即可。
Docker 官方镜像:https://hub.docker.com/r/obpilot/oceanbase-ce
📢📢📢 下载镜像:
docker pull obpilot/oceanbase-ce:latest
📢📢📢 新容器创建
docker run -itd -m 10G -p 2881:2881 -p 2883:2883
–name oceanbase-ce obpilot/oceanbase-ce:latest
📢📢📢 进入容器
[root@jeames ~]# docker exec -it oceanbase-ce bash
进入容器后,可以看看 readme.md 文档
-- 查看集群列表
[admin@3ef732cfb95a ~]$ obd cluster list
配置文件:/home/admin/.obd/cluster/obdemo/config.yaml
-- 启动集群
[admin@3ef732cfb95a ~]$ obd cluster start obdemo
如果遇到以下两个报错
[ERROR] (127.0.0.1) open files number must not be less than 20000 (Current value: 1024)
[ERROR] (127.0.0.1) not enough memory. (Free: 6.7G, Need: 8.0G)
一个是用户最大打开文件数不够,一个是可用内存不足8G,解决后成功启动。
