Cannot start server in Centos 7

Couchbase Server
1

I’m installing Couchbase 5.1.1 community on Centos7 (centos-release-7-5.1804.el7.centos.2.x86_64), already have run below commands:

  • setenforce 0

  • systemctl daemon-reexec

And had tried reinstalling Couchbase server after these 2 commands, the result is:

Redirecting to /bin/systemctl status -l couchbase-server.service

Hi littlewitchanita,
Thanks for using our Couchbase Server.
I tried on CentOS 7.4 and did not get any issue.

I will update my server and rerun your steps above

After update my centOS server to 7.5, I could not reproduce the issue following your steps above.

Hi, thanks for the reply. In my case, I will see “Permission denied” in the installation step already if the 2 commands have not been run.

I have rolled back to Centos 6 for the time being, will take a look again on Centos 7 in the near future.

Thanks.

I have a question.
Since Couchbase Server for Centos 6 and Centos 7 are different in installation, what Couchbase Server version did you install on Centos 7?
You mention that 2 commands have not been run. Which commands are they?
Thanks

I’ve been using Couchbase 5.1.1 community for Red Hat 7 for Centos 7, and Red Hat 6 for Centos 6.

I’ve even tried installing the one for Red Hat 6 on Centos 7, it succeeded, but the CPU kept on quite a high level even with no request. So I don’t think the version for Red Hat 6 is suitable for Centos 7.

The 2 commands are:
setenforce 0
systemctl daemon-reexec
