I installed the latest version Nexus 3.21.1-01 on my Centos7 server under the user root.

After reading the help document ’ [Run as a Service](https://help.sonatype.com/repomanager3/installation/run-as-a-service)’, I created a new user ‘nexus’ and change the `bin/nexus.rc` file to `run_as_user="nexus"`.

And then I also change the configuration like the article to let nexus run as a service.

Now when I want to start the nexus using command ‘nexus start’, the server can not start like the following:

 ![nexus](https://canada1.discourse-cdn.com/flex047/uploads/communitysonatype/original/2X/b/ba94abe77efd0b22a01482526ac2796722d53e03.png)

I google the whole website but do not find the answers.

Any help will be preciated!
