CENTOS下SAMBA服务不能开启的解决方法

Job for smb.service failed because the control process exited with error code. CentOS 7

I have this problem with my CentOS 7.2 server which will not start samba server anymore.

For example if I run:

systemctl restart smb.service

I will receive some garbage value like:

Job for smb.service failed because the control process exited with error code.
See "systemctl status smb.service" and "journalctl -xe" for details.

I read that this command can make sure if my config file is perfectly good:

smbstatus

And I received:

WARNING: Ignoring invalid value ‘share‘ for parameter ‘security‘
Can‘t load /etc/samba/smb.conf - run testparm to debug it

So I go to my config file /etc/samba/smb.conf and commented one line which starts with security:

#security = share

Now when I re-launch smbstatus it says:

Samba version 4.2.10
PID     Username      Group         Machine            Protocol Version
------------------------------------------------------------------------------

Service      pid     machine       Connected at
-------------------------------------------------------

/var/lib/samba/locking.tdb not initialised
This is normal if an SMB client has never connected to your server.

After all I try to start samba server again and succed:

systemctl restart smb.service
