Hi @wwwjljj,

Thanks for your post. As mentioned in the logs,  
`2020/08/24 07:33:05 mkdir w: permission denied`  
`Error while creating WAL dir.`  
`2020/08/24 07:33:05 mkdir zw: permission denied`  
`Error while creating WAL dir.`  
the command is not able to create w , d, zw directories. These directories are used by dgraph to store data. I suspect dgraph was run before reboot as root or by different user. Could you check permissions of d, z, zw directories ?

I have changed the right by the command :“chmod 777 -R ~/dgraph” , but there is still a error：

```auto
[root@kg ~]# chmod 777 -R dgraph
[root@kg ~]# docker run --rm -it -p 8080:8080 -p 9080:9080 -p 8000:8000 -v ~/dgraph:/dgraph dgraph/standalone:latest

Are you running dgraph as a root user ? Are you able to create any other directories using mkdir in /root directory ?

To reinstall dgraph with docker, you will have to delete dgraph images using

> docker image rm

and then run

> docker run --rm -it -p 8080:8080 -p 9080:9080 -p 8000:8000 -v ~/dgraph:/dgraph dgraph/standalone

command. It will again download dgraph image and run dgraph.

That’s great to know.

I have been trying to recreate the issue but went into issues with aufs mounting while running docker on docker. Could you share any other details of your setup. Are you using centos docker container and trying to run dgraph over it ? Can I close this topic if your issue has been resolved ?

Sure, you can close this topic.  
Just colse Se-linux, nothing else:

```auto
setenforce 0
vim /etc/sysconfig/selinux
# set SELINUX=disabled
