Automatic nightly YUM updates with yum-cron

yes, its centminmod beta. I've removed postfix and replaced with ssmpt to use with mandrill.

---

Thanks for your help

 

This one seems working for me, as I didn't update ES to 1.5.1 knowing it's updated now
But I don't receive an email :/

 

If i just install yum-cron and edit the /etc/yum/yum-cron-hourly.conf it will run every hour?

And if i want to run it every 30 minutes how can set it?

 

On Centos 7.1 i can't find the:

Code:

CHECK_ONLY=

What i am doing wrong?

I can't find it on the daily file:

Code:

/etc/yum/yum-cron.conf

and can't find it also at the hourly:

Code:

/etc/yum/yum-cron-hourly.conf

 

Yes as i can see all the rest settings:

Code:

yum-cron.noarch                    3.4.3-125.el7.centos

nano /etc/yum/yum-cron.conf

Code:

Does that mean that i must set it to yes to get the notification on my email?

Code:

# Whether a message should emitted when updates are available.
update_messages = no

Bad english here sorry

 

And i miss also this parameter:

Code:

YUM_PARAMETER=

Any other related?

 

It is useful to exclude something that you don't need

Anyway, last question:

Code:

# default  = yum upgrade

There is no yum update as an option as yum upgrade removal of obsolete packages can be risky, as it may remove packages that i use?

 

Ok this is what i did just to get a notification for updates on every hour check without downloading/installing anything:

Code:

yum -y install yum-cron
systemctl enable yum-cron.service
/bin/systemctl start  yum-cron.service

nano /etc/yum/yum-cron-hourly.conf

Code:

update_messages = yes
download_updates = no
apply_updates = no
system_name = Server5
emit_via = email
email_to = myemail@gmail.com

/bin/systemctl restart yum-cron.service

And i am waiting for an email as i check manually and there are updates waiting

 

Ok i set it at 00:30 about and now is 01:06 and no mail at all and running manually yum upgrade i can see updates waiting there

Any ideas?

Code:

[root@vultr ~]# grep yum.cron /var/log/cron | tail -10
[root@vultr ~]#

Code:

[root@vultr ~]# tail -10 /var/log/yum.log

Doesn't seem to run and i was use:

systemctl enable yum-cron.service
/bin/systemctl start yum-cron.service

and after editing the config i run:

/bin/systemctl restart yum-cron.service

I think is the same as your commands but i run them again anyway:

Code:

[root@vultr ~]# service yum-cron start
Redirecting to /bin/systemctl start  yum-cron.service
[root@vultr ~]# chkconfig yum-cron on
Note: Forwarding request to 'systemctl enable yum-cron.service'.

Is there any other way to check that is running ?
