Automatic nightly YUM updates with yum-cron

FYI, if you don't want yum-cron email alerts to be sent from root@yourhostname.domain.com but from a different address, you can.

---

For CentOS 7 has another option in /etc/yum/yum-cron.conf for email_from field

Code:

[email]
# The address to send email messages from.
email_from = root@localhost

# List of addresses to send messages to.
email_to = root

# Name of the host to connect to to send email messages.
email_host = localhost

on CentOS 6 version of yum-cron no such native email from option but you can probably hack the file at /etc/cron.daily/0yum.cron near the end

Code:

if [ ! -z "$MAILTO" ] && [ -x /bin/mail ]; then
# if MAILTO is set, use mail command (ie better than standard mail with cron output)
  [ -s "$YUMTMP" ] && mail -s "System update: $SYSTEMNAME" $MAILTO < $YUMTMP
else
# default behavior is to use cron's internal mailing of output from cron-script
  cat $YUMTMP
fi 

the section

Code:

mail -s "System update: $SYSTEMNAME" $MAILTO

can add -r EMAILFROMADDR, so if you wanted to send from same address as to address already filled out

Code:

mail -r $MAILTO -s "System update: $SYSTEMNAME" $MAILTO

 

need to wait for CentOS / RHEL 7.3 which according to that bug report is due in a few months, when it get's closer to 7.3 beta, it should be available in centos continuous release repo or even fasttrack as well

Code (Text):

yum list updates -q --enablerepo=fasttrack,cr --disableplugin=priorities

 

yes you can use pushover email

 

unfortunately centos 7 yum-cron doesn't support that

 

yeah seems to in centos 6 yum-cron config file at /etc/sysconfig/yum-cron it has YUM_PARAMETER which takes yum parameters

example to exclude MariaDB* packages from yum-cron

Code (Text):

# Pass any given paramter to yum, as run in all the scripts invoked
# by this package.  Be aware that this is global, and yum is invoked in
# several modes by these scripts for which your own parameter might not
# be appropriate
YUM_PARAMETER="-x MariaDB*"

On CentOS 6 yum-cron, you can maybe try

Code (Text):

# Pass any given paramter to yum, as run in all the scripts invoked
# by this package.  Be aware that this is global, and yum is invoked in
# several modes by these scripts for which your own parameter might not
# be appropriate
YUM_PARAMETER="--disableplugin=priorities --enablerepo=remi -x MariaDB*"

FYI, for a long time now I have been writing on my own custom version of yum-cron for centmin mod auto yum updates seeing as yum-cron is just a bash script I should look at rolling it out eventually and it should support both --disableplugin=priorities and --enablerepo= flags

 

centos 6 could but not centos 7 for yum-cron AFAIK

 

list yum packages files installed

Code (Text):

rpm -ql yum-cron

 

yeah centos 7 version of yum-cron went backwards compared centos 6 yum-cron for supported features. That's why i am working on a custom yum-cron like script tool for Centmin Mod which will more extensive to support all Centmin Mod installed or available yum repos

 

Yeah not ready at my end for my version so for CentOS 7 users you can also setup your own cronjob if you really need for such.
