Qt5 from repository with *devel packages but with no debug symbols on Centos 6.5
location: linuxexchange.com - date: February 23, 2014
I am trying to determine a reason for application crashing on Centos 6.5. I have qt5 from EPEL repositories installed complete with all -devel packages, but both gdb and qtcreator seem to think that I do not have debug symbols for Qt libraries... do I need to compile Qt from source or is there a way to make the one from repo work for debugging?
CentOS, Fedora, or Ubuntu for server. Which is best?
location: ubuntuforums.com - date: May 20, 2008
The title sums it up. And, posting this on an Ubuntu forum, I know beforehand that the answers might be a little biased.
But the gist of it is that I may soon need to set up and periodically administer a box that will be used for subversion, among other things. I've been using Ubuntu since Feisty on might desktop and have loved it overall. My first instinct is to go ahead and load Hardy LTS on the new server, but then again Fedora seems to be the go-to distro for servers.
I realize that Canonical is working hard to make Ubuntu a server household name in its own right with some already evident success, but I know Fedora supposedly has a history of being a strong server platform, and nearly every server I've seen in the past is usually running some form of Red Hat-inspired software.
Come to think of it, I had forgotten about CentOS. How does that stack up?
I haven't really administered a server of any kind before, so I'd appreciate honest assessments of each distr
Ubuntu Server Edition vs. CentOS?

I've had dedicated servers hosting my websites for years now, though I admit I have no server administration or management experience. My dedicated servers are currently run off of CentOS 64-bit, though I am interested in using Ubuntu Server Edition 64-bit.
I'd like to compare and contrast the two, in terms of performance, ease of use, stability, and security. I know they are both Linux distributions but the two are based off of two different ones: Red Hat & Debian.
One day I would love to learn how to fully administer and manage my server myself. That's one of the reasons I'm leaning towards Ubuntu, because of its documentation and large community support forum. I just don't want to lose performance, security, or stability by switching from CentOS to Ubuntu Server Edition.
Can anyone really compare and contrast the two in a server environment? I've used Ubuntu as a desktop OS before, though I really didn't like it as much as openSUSE. Not only that but Ubuntu di

Now I'm looking for one enterprise distribution for servers and desktops. And I'm choosing between Ubuntu and CentOs.
Ubuntu is the best desktop and server solution, with many installations and good support. But there is no free systems management tool - Landscape server is not open and free.
CentOs - I've never worked with it before and I can't say something about it. But for CentOs there is open source system management tool - Spacewalk.
So, what would you advise me?
centOS vs ubuntu

Hi all, quick question. I am new to Linux and recently upgraded my hosting plan to a VPS. I was on ubuntu (but didn't have full ssh) and now I am on centOS which is all they offer for this type of plan.
I would prefer to use ubuntu since I am most familiar with it and our Moodle server at work runs on it. Part of why I upgraded was have full root privileges and get more familiar with linux and learn.
How similar are centOS and ubuntu - or any linux distro for that matter? Do all linux distros have very similar directories and commands? I know there will be differences like yum/apt-get but if I get good and comfortable with centOS will I be thrown into another world if I try to work with ubuntu and others?

I am really in a need to know major differences in between for those who used both centos and ubuntu servers regarding VPS.
And which one is better regarding stability and security and memory usage?
Ubuntu Server Or CentOS

Hey guys I am soon to deploy a new server for quite a bit of things such as web serving, Game Servers, and File Hosting. I have one main question is whether to go with Ubuntu Server 10.10 or CentOS 5.5 in terms of reliability, uptime, expandability, and the most professional one to use. It would be great to read some of your opinions. Also if you would like you can also post what you think is the best overall server operating system.... Thank you in advance
Ubuntu Vs. CentOS/Fedora differences in command line
location: ubuntuforums.com - date: May 21, 2010
I am planning to have two linux home severs. One “always on” Ubuntu server with SAMBA, FTP, etc and another one CentOS/Fedora that boots up once a day, backups my Ubuntu server and shuts down. Both will be headless.
I have the Ubuntu Server up and running. Before I setup the CentOS/Fedora backup server, I would like to know:
1) how different CentOS/Fedora is from Ubuntu in terms of managing the server from command line.
2) Are the commands very different. I am willing learn a bit but is the difference so huge that it will take days for me to setup up the backup server?
3) Are the directory structures/files very different? For example, in Ubuntu I know where sources.list (/etc/apt/sources.list) is it the same in CentOS/Fedora or is it the same for most part?
I know Ubuntu uses deb and CentOS/Fedora uses rpm. Other than this what else might be different. I have no experience on a rpm based linux. I am fine managing my ubuntu server from command line. I can easily setup

I currently have one laptop with a version of arch linux installed which has 2 faulty dhcp clients, and I can't work with it, so I have to reinstall another version of Linux.
I wanted to try a version of red hat linux, so my question now:
Which one is better, fedora or CentOS ?
I mean better in terms of stability and mainly in the number of available packages. Also, do both have the same package manager, or is one notably better?
Anybody has any experience with those?
SLOW Ubuntu Server vs CentOS MySQL Disk Access
location: ubuntuforums.com - date: January 14, 2009
I don't belive Ubuntu should compile the standard kernel with these options:
They SHOULD BE for any new server or servers no older than say 3 years old:
At the very least, Ubuntu should have a standard kernel package we can apt-get that has the clock set at 1000.
So, we have recently spent a very long time trying to track down problems with our MySQL server.
Our requirements are high concurrency, high load, and ACID transaction compliance.
We use InnoDB in MySQL for our database. To increase the safety of the data integrity, we turn "sync-binlog=1" in the MySQL my.cnf. We notice this basically killed all performance on our server... essentialy 98% performance hit on our ubuntu64 10GB Ram with Raid-1 sas with battery backed up cache.
We tried configuring MySQL 4.1, 5.0, 5.1, 6.0 and the config logs hundreds of times. Nothing we did would improve our performance.
