1, the error message when you start nfs-server command with systemctl
1) system environment:
[root@vms001 /]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.1 (Maipo) [root@vms001 /]# uname -r 3.10.0-229.el7.x86_64
2) an error message when you start nfs-server:
[root@vms001 /]# systemctl start nfs-server.service Job for nfs-server.service failed. See 'systemctl status nfs-server.service' and 'journalctl -xn' for details.
2, find the cause of an error
① "Based on the above error message alert See 'systemctl Status nfs-server.service '", please refer nfs-server service status information.
② According to error prompt, we enter systemctl status nfs-server nfs-server service to view status information, the code is as follows:
[root@vms001 /]# systemctl status nfs-server.service
nfs-server.service - NFS server and services
Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; enabled)
Active: failed (Result: exit-code) since 四 2019-06-20 16:39:47 CST; 7min ago
Process: 4092 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=1/FAILURE)

6月 20 16:39:47 vms001.example.com exportfs[4092]: exportfs: Failed to stat /xx: No such file or directory

6月 20 16:39:47 vms001.example.com systemd[1]: Unit nfs-server.service entered failed state.
③ According View nfs-server state information service, found that more than exportfs: Failed to stat / xx: No such file or directory section (exportfs: stat / xx failed No such file or directory).
④ Why is there no prompt / xx such file or directory it? This may be before we configured the shared directory nfs, but we do not have the shared directory, so when we start nfs-server services are being given this prompt. Then take a look at whether we really have configured / xx shared directory, the code is as follows:
[root@vms001 /]# cat /etc/exports ############################## /xx 192.168.26.0/24(rw,sync)
According to the above code, found in the / etc / exports configuration file which is really a / xx shared directory. Then we look at the creation / xx or delete the directory / etc / exports configuration file inside / xx this share.
3, the solution
1) create / xx directory
[root@vms001 /]# mkdir /xx
2) Start nfs-server service again
[root@vms001 /]# systemctl start nfs-server.service
3) Check nfs-server service status
[root@vms001 /]# systemctl status nfs-server.service
nfs-server.service - NFS server and services
Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; enabled)

Main PID: 4594 (code=exited, status=0/SUCCESS)
CGroup: /system.slice/nfs-server.service
Results: Based on these results, we have created / xx directory to start again after nfs-server succeeded.
