Package Management
by centos＠rio.vg 02 Jun '06

02 Jun '06

What does CentOS use for general package management? SuSE has YaST, Ubuntu has Synaptic, what does CentOS use? I've got CentOS running on a test server, but the documentation is pretty thin on where to begin. If there a central area for these sorts of programs or naming convention?

RE: [CentOS] centos & mysql

You need to grant the privs to allow the connection. They mysql homepage has a set of docs at http://dev.mysql.com/doc/. More specifically this link which talks about setting up the grant tables http://dev.mysql.com/doc/refman/4.1/en/post-installation.html You could also use phpmyadmin to have a nice frontend to the mysql server system (http://www.phpmyadmin.net/home_page/index.php) Some things to consider: (since you said you were a newbie) 1. If no remote apps are going to be connecting the sql server port (ie only local programs relative to the system), do not open iptables for the sql server port. 1b. configure the /etc/my.cnf file to tell mysql to use local sockets and not listen on a port (skip-networking option). 2. When adding users, never grant a user profile in the mysql table any privs (excluding the default root which you should also rename to something else) as doing so would allow the user those rights across all databases. Instead grant users access via the mysql::db table. Also there is alot of good how-to docs at http://www.hughesjr.com/ for centos, specifically http://www.hughesjr.com/content/view/13/30/Guides -greg ________________________________ From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Stephen A.

RE: [CentOS] PERL module woes

It does not resemble what I would > consider to be rational thought. I think I understand what he was trying to say. When I built my last system, I decided to go with rpms for everything. It worked great until I got to the Perl modules and then it fell apart. Every time I have tried to install Perl modules from rpms, it quickly evolves into a massive game of "find the missing dependency". Either the module I want can't be found anywhere, or when I do find it, it depends on a module that can't be found. I finally gave up and decided to use CPAN for Perl modules. It is simple, and work amazingly well. It does cause some annoyance when you get other rpms that have dependencies on Perl modules, but that is a problem that I have only seen once or twice. There is a program that will create rpms from CPAN. I considered it and then rejected it as being WAY too much trouble for the number of modules that I typically deal with. -- Bowie

getting update details
by Mark Belanger 02 Jun '06

02 Jun '06

I see in CentOS 3.6 - the release notes state that it has "improved support for dual-core processors" I got that from http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/release-notes/a… Where might I get more details about this improved support. Specifically I'd like to see if problems I'm having in 3.5 could be related to the kernel and dual core cpus. -Mark -- Mark Belanger LTX Corporation

RPM install vs. NFS mount and code versioning
by Alfred von Campe 02 Jun '06

02 Jun '06

The ongoing discussion regarding Perl modules and RPMs, prompted me to post an issue I am currently facing. I support a development team that uses various third party tools, some free, some not, some of which are installed via RPMs, and some that are not. The development cycle is 18-24 months long, and then there are many years of support (continuing engineering) after that, for which the various versions of the tools need to be available. There are a few dozen engineers on the project. Let say that I want to install SuperTool V1.1, and it's available to install only via RPMs. After thorough testing/qualification on one workstation, I need to install it on the few dozen workstations, which is straightforward but possibly time consuming (and you have to deal with workstations that may be down when you are doing the installs). When V1.2 comes out, I can again test it on one workstation, and then deploy it on the remaining workstations. But what if I there is a bug, and we need to test it against the old version of the tool? With RPMs, it is cumbersome to go back and forth between versions. Contrast that with a tar based install, where I can untar the tool in a directory that includes a version number in the path, and then automount that directory to all the workstations. There is only one install, and I can easily move back and forth among the various versions. Now I understand the benefits of RPMs, but when it comes to supporting tool vendors, dealing with tar based installations and using automounts really simplifies things. I am thinking about installing the RPM based tools on one system, and then copying the entire install tree to a NAS and automount it. I know this is not ideal, but I can't think of a better solution. Any thoughts from the members of this list? Have you tried to solve similar problems in the past? If so, how did you do it? Alfred

Re: [CentOS] [CSL #301925] centosplus kernel xfs patches and CVE-2006-1855

Johnny Hughes wrote: > >There is a centosplus kernel that has that errata ... it is version: > kernel-2.6.9-34.107.plus.c4 Excellent. Is there a general way to map from upstream errata kernels to centosplus kernels? The (apparently??) previous convention of suffixing .106.unsupported to the upstream release number seemed to work well, and I don't want to either guess or take up mailing list bandwidth asking every time upstream revs. >However ... if the only thing you need from the centosplus kernel is the >xfs ... you should use the normal (non-centosplus) kernel and the >kernel-xfs-module that matches it from here: > >http://dev.centos.org/centos/4/testing/i386/RPMS/ > >or > >http://dev.centos.org/centos/4/testing/x86_64/RPMS/ Ooooh. That would be cool. I'll look into it. Thanks again. Dave Thompson UW-Madison

Installing el3 packages on CentOS 4
by José Alburquerque 01 Jun '06

01 Jun '06

Is it possible to install el3 packages on CentOS 4? I'm wondering because there are some packages on dag (for example ac3dec) that are built for el3 and not for el4. Is it better to rebuild the source rpm? Thanks. Sincerely Jose Alburquerque

[CSL #301925] centosplus kernel xfs patches and CVE-2006-1855
by David Thompson 01 Jun '06

01 Jun '06

Hi All, we've run into a problem with the xfs component in the centosplus kernel (2.6.9-34.106.unsupportedsmp) where synchronous writes sometimes fail with EAGAIN. It's causing headaches for DB2 installs and for our database research group. There is a fix reported at: http://marc.theaimsgroup.com/?l=linux-xfs&m=110808122904352&w=2 ...that's supposed to take care of things. If there is any way these patches could be included in a future centosplus kernel, we would greatly appreciate it. We are enjoying the performance lift from xfs on many systems, and hate to throw it away to get a database to work. Also, are there plans to produce a centosplus kernel that corresponds to the newest RHEL errata kernel (2.6.9-34.0.1.EL)? Cheers and thanks, Dave Thompson UW-Madison
