What if there is an error in Faild to create 1 monitor when ceph-deploy installs the I version

This article mainly introduces ceph-deploy installation I version of Faild to create 1 monitor error how to do, the article is very detailed, has a certain reference value, interested friends must read it!

The environment is centos7.1+ ceph9.2.1

Report an error at the mon create-initial step when deploying using the deploy tool

According to the error report, the file is missing, and it is found that there are no files that the mon service needs to start.

Create manually under / usr/lib/systemd/system:

# cd / usr/lib/systemd/system#cp ceph-mon\ @ .service ceph-mon\ @ node-182.service

Then I found that the mon service could be started; the same was true when creating the osd

Ps: if the network yum source is configured, this problem will not occur after yum update upgrades the system, indicating that the problem should have something to do with the version of linux (or, to be exact, systemd).
