[CentOS] gnome / gdm mess
Hello, My first attempt to install Gnome is not a bright success. If I boot in runlevel 5, using gdm, I get the login screen, but after login I get sometimes only the root window (no icons, no toolbar, no menu, nothing but keyboard shortcuts), sometimes the icons are here but not the toolbars... If I use startx from runlevel 3, everything is fine. As I don't know Gnome, I have very probably messed something during install (CentOS-6, x86_64, using uptodate netinstall iso, starting from Minimal Desktop). But I have no clue about where to look, or how to debug it. Can someone point me to some useful doc ? P.S. I'm surprised to see gdm and X running on tty1 (in runlevel 5, not 3). Is it correct ? Thanks for your help, -- Philippe Naudin ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] R packaging question
I have been working on packaging (for internal use only) multiple
versions of R (eg 2.14.1, 2.14.2, 2.15.0) such that I can install these
RPMs and provide the different versions of R (especially 2.14.x and
2.15.x) to the biostatisticians that require them. I have been messing
around with the R.spec file but I have been unable to get the package to
provide R in the location I would like:
/usr/lib64/R-2.14.1/
/usr/lib64/R-2.15.0/
Now I know this can be done but I am just having some difficulty in
getting it to work correctly. I have tried multiple variations in the
spec playing with adding -%{version} to the paths within the spec file,
as well as even using -libdir=/usr/lib64/R-%{version} which works to a
point, but basically provides:
/usr/lib64/R-2.14.1/R/
/usr/lib64/R-2.15.0/R/
I have attached the spec file I have been modifying and would appreciate
any insights into getting this packaging correct.
Thank you in advance for any assistance

[CentOS] How to rotate PHP error log - since it belongs to apache
Hello, I'm using CentOS 6.2 with the stock rpm php-5.3.3-3.el6_2.8.x86_64 and the following /etc/php.ini file: error_reporting = E_ALL & ~E_DEPRECATED display_errors = Off error_log = /var/log/php/php_errors.log and that file is very useful for me because I have many custom PHP-scripts at my site, but that file keeps growing too... :-) So my question is for how to rotate it (esp. since it should be owned by "apache" user) - what do you guys use?

yes, I'm aware of that file and have modified
the docs path in it because I have several vhosts too...
Here is my current /etc/logrotate.d/httpd file:
/var/log/httpd/my_vhost_1/*log {
missingok
notifempty
sharedscripts
delaycompress
postrotate
/sbin/service httpd reload > /dev/null 2>/dev/null || true
endscript
}
But my problem is I don't know how to do it best -
i.e. where to put the PHP log file
/var/log/php/php_errors.log
in the directives above and also how to rotate
the logs for all vhosts I have (I currently rotate just
for one - the "my_vhost_1" as you can see above)

[CentOS] custom kernel build
Hi all, I have donwloaded 2.6.32.59 from kernel.org, extracted the source, did make menuconfig to select/deselect items then did make bzImage, make modules, make modules_install, make install and rebooted. first message I got was that ext4 was not supported. So I verified that ext4 was selected and it was. So I looked at the size of the /boot/initramfs* items. My custom one is really small compared to the normal one. My question is - what controls the items that get put in there (the initramfs stuff) when you do a "make install" for a custom kernel? Clearly it is not picking up the "normal" centos items that are in the other initramfs files. Thanks, Jerry ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] 75% - 80% Rebuild Complete
First I want to thank all of you who responded to me both on this list and in the CentOS wiki. Your responses helped greatly! I want to say that if you are running CentOS 5 and you do not have a overriding reason to go to CentOS 6, stay where you are. It was so much easier installing CentOS 6 on a new machine, migrating is next to impossible. Here's where I am today: 1. The base DVD install would not allow me to run the gnome desktop at 1920x1080 resolution with the default nVidia driver, the highest resolution I could obtain was 1024x768. However the text screen worked just fine after I introduced the video=1920x1080 in the grub.conf file. 2. When I installed the nVidia closed source drivers, the gnome desktop ran perfectly in the high resolution mode. The text mode then dropped to 1024x768 even though it retained the video=1920x1080 parameter (could it be those blacklist parameters introduced to disable the noveau drivers?). 3. During the installation I instituted software raid-1 along with LVM. It all worked perfectly until I got to the Boot Loader screen and instead of using the default (/dev/sda) I used what I thought would work in a raid-1 environment IF one of the hard drives went bad. I chose to install the boot loader in /dev/md0. Of course it would not boot. I recovered from this by going through the install and choosing to upgrade a existing installation and it allowed me to place the boot loader in /dev/sda. What that leaves me with is a raid-1 environment that works great as long as /dev/sda remains. How do I fix that??? 4. I still need to add all of those extra repositories (adobe; webmin; rpmfusion; etc). 5. I'm still trying to decide if I want a high resolution text screen (that I would use almost everyday) or a high resolution GUI screen (that I'll only use for certain application installs)??? At my 'real' job, we use RHEL and we've done some things using RHEL 6.2 for POC (Proof Of Concept) projects. With a POC, we install using a standard installation DVD (as opposed to using our RH Satellite Server). All of this to say that there are application installation options that really fit the needs of a server installation, you can choose 'Server' and 'Server GUI', which installs the gnome GUI without selecting a desktop environment.. Some things we run require a GUI to install (Oracle DB; IBM DB2 UDB; IBM WebSphere; etc.). How do I select this type of environment using CentOS 6.2? In other words, I'm running CentOS 6.2 x86_64 Desktop TIA, Gene Poole + It's impossible for everything to be true. + ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Better question than it appears at first glance ;) . Nothing in man rsyslog.conf on C6, but on C5 man syslog.conf it says under "ACTIONS", "Regular File": "You may prefix each entry with the minus ‘‘-’’ sign to omit syncing the file after every logging. Note that you might lose information if the system crashes right behind a write attempt.

The MBR isn't mirrored, so you just have to install grub on the other drive, usually by executing grub, then: grub> root (hd1,0) grub> setup (hd1) but the numbers depend on how bios sees the alternate drive when the primary dies. It is always a good idea to practice re-installing grub from an install disk booted in rescue mode so you know how to fix things even if you have to move your mirror disk into the primary position to make it boot. > 5.

If you sit at the machine, you probably want a high res gui and to do text work in terminal windows. If you don't sit at the machine you probably don't even want X installed for the console. Run freenx for occasional (or even regular) remote GUI access, or use ssh with X forwarding for single GUI applications at a time. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Create a different file under /etc/logrotate.d (perhaps name it
"phplog", doesn't really mater though) and add the appropriate
configuration options. I used this website to help me with the
necessary options (though the man page is more than sufficient as well):
http://www.thegeekstuff.com/2010/07/logrotate-examples/
Here is a custom logrotate conf I created for my catalina logs:
[root@390405-web1 images]# cat /etc/logrotate.d/tomcat
/opt/apache-tomcat-5.5.34/logs/catalina.out {
daily
copytruncate
delaycompress
missingok
postrotate
/root/bin/catlog_mv.sh
endscript
}
If you were wanting to rotate according to the size of the file (perhaps
512MB, whatever works for you though) owned by apache, you might create
a file under /etc/logrotate.d/ containing something like the following:
/var/log/php/php_errors.log {
size 512MB
create 644 apache apache
missingok
compress
}
There's all kinds of other options you can add as well. Read the
article I linked earlier and/or the man page, it's really pretty
trivial. Good luck :)

There was a small hitch in that the "Twinview" option wasn't available (it was present but grayed out) on the NVidia control panel, but entering nvidia-xconfig --twinview on the command line as root did the trick.

[CentOS] cluster.conf validating, but cman not starting
Hi all,
since the last yum update cman does not start any more with the
following entries in /var/log/messages:

But the cluster config is okay:

> Configuration validates
Before the last yum update the cluster config was okay, cman started.
The config has not been changed.
Has anyone run into this problem? Even disabling config validation in
/etc/sysconfig/cman does not change this behaviour.
I am lost, and my cluster does not start. Any hint or help is highly
appreciated.

I've updated CentOS 6.x clusters without issue. Please paste you
cluster.conf, obfuscating only passwords please.

Yes, and RHEL5 will be supported for several years. However, there does not appear to be a plan to support Xen in the future, after RHEL5 expires. It would be irrational to invest time and money into training on Xen with no expectation that those skills will remain valuable in the future. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] 75% - 80% Rebuild Complete
OK, I'm about 90% sure that I've corrected the boot loader situation with RAID-1 and the second hard drive. I haven't tested the correction, but here's what I did: Examined the grub.conf file and noticed that hd0 uses (hd0,1), so what followed was grub grub> device (hd1) /dev/sdc grub> root (hd1,1) grub> setup (hd1) grub> quit I didn't rebuild the boot loader on /dev/sda because it is working (if it ain't broke don't fix it). My situation is that I'm using 4 - 1 TB hard drives and I used the following pattern: /dev/sda | /dev/sdc = First Raid -1 volume /dev/sdb | /dev/sdd = Second Raid-1 volume Thanks all for the suggestions and thoughts!

[CentOS] Mysql cluster vs. mysql-libs
Hi, it seems even a minimal install of Centos 6.2 now requires mysql-libs as a dependency for postfix and cronie. When I try to install the mysql cluster rpms from mysql.com I get a collision between the files. Since this is the first time I get into contact with mysql cluster I wonder if somebody has an idea how to resolve this or knows alternative packages that don't conflict with mysql-libs?
