obd版本是多少，之前存在obd连接失败bug 实际上已经完成。
手动连接一下试试 -h127.0.0.1 -P2881

#4

root@xyh-NF5468M6:~# obclient -h127.0.0.1 -P2881 -uroot -p -c -A
Enter password:
ERROR 8001 (08004): Server is initializing

版本是4.2.3

#5

obd 2.9

#6

ulimit -a 查看下内核参数。
df -h看一下磁盘大小并且再提供一下机器的内存和cpu

这边看内存很富裕，你root的目录大小多少demo集群默认安装在用户home目录下的，提供一份observer日志看一下，cd /root/oceanbase-ce/log下
规范点创建个admin用户尝试下，方便后续搭建集群规格建议配置下ssh免密

#13

observer.zip (15.2 MB)

之前进行安装时候admin用户安装不上，原因记不清了，就用的root

#14

日志中报错4184问题，磁盘空间不足。应该是/root目录不够大
你试试使用obd web搭建方式。手动把数据磁盘路径和log盘路径修改到其他地方

你好，问题解决了么
