已提前创建好普通用户，并配置了sudo权限
admin ALL=(ALL) NOPASSWD: ALL

yaml 中设置好账户及密码
user:
username: admin
password: xxx

安装时报错
$ obd cluster autodeploy obtest -c 1.yaml

在admin账户下，手动执行mdkir成功
su - admin

ob 支持普通用户安装，问题在于，提前设置的数据目录和日志目录，/data/xxxx admin 没有权限，你chown 一下试试

可以了，谢谢，但是又有新问题，destroy时报错如下：

$ obd cluster destroy obtest -f

obtest destroyed

admin有sudo的所有权限，且目录权限也是正确的：

$ ll /data/ | grep ob
drwxr-xr-x  2 admin admin    6 Nov  4 16:33 obagent
drwxr-xr-x  2 admin admin    6 Nov  4 16:23 obproxy
drwxr-xr-x  2 admin admin    6 Nov  4 16:33 obredo

destroy失败，应该是你admin没有父目录/data的权限

#6

admin用户已经授予sudo all权限了呀

#7

在销毁的时候不会加上sudo
sudo免密只有在切换用户的时候OBD会用到
