Hi everyone, I'm new to this list, so I apologize if my email is not in
keeping with the procedures. I am a newbie with RHEL 5.7 system
administration and recently registered our web server with Red Hat (this
past Monday). Upon registration, I noticed online that the server needed
506 updates and so I set the auto errata to enabled. By the time, I
realized my mistake there were only 217 updates left to be done. I
changed the auto errata to disabled and locked the account to stop the
rest from going through on their own.
Hi, Constance,
You've probably got several things going on.
First, finish the full updates, really. 5.7 is several years old - it's now
on 5.9, for the 5.x branch (the 6.x is up to 6.4 as of several months ago)
and if you type lsb_release -a, that's what you should see. Having it partly
updated is asking for trouble, esp. if interrelated packages are not all
installed, such as an application like apache, but libraries it needs aren't
updated.
Second, when you do a reboot, it *will* have major issues, unless you finish
that update, for the reason above.
Third, if this is a server, and *esp* if it's a production machine, I would
recommend turning off yum-updatesd (that's the auto-updated; it doesn't
exist in 6.x) - you should consider the updates, and coordinate if there's
something that your users might see, like NFS or apache, etc.
Immediately following, I was unable to use Putty to ssh to the web
server. A co-worker worked with me to get us access again by updating the
And, presumably, restarting sshd (service sshd restart).
sshd_config file. However, we have some clients who use Expression Web 4
to update sites and they cannot gain access. It says "There's no site
named 'blah' " when they try to login.
This would have to do with the apache configuration (httpd); that's in
/etc/httpd/conf and /etc/httpd/conf.d Sounds to me as though the virtual
hosts are messed up, or possibly that you have secondary IPs, for which you
need to look at /etc/sysconfig/network-scripts.
*Do* run yum update regularly. RH should be emailing you about updates;
anything labelled "critical" (like firefox) should be done that day;
important, if you read what it fixes and find that it affects you, in the
next couple of days. What I did at work, several years ago, was to talk to
the system owners, and set up a regular monthly maintenance window, when I
could do full updates - bug and security fixes - and reboot as needed. And
they make sure their users know of the window.
