2. Introduction

Welcome to the CentOS 5.10 release. CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by our Upstream OS Provider (UOP)¹.

CentOS conforms fully with the upstream vendor's redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is a Free Operating System.

CentOS 5.10 is the tenth update to the CentOS 5 distribution series. It contains a lot of bugfixes, updates and new functionality. Before reading any further we advise you to read the UOP Release Notes and Technical Notes². The rest of this document is an addendum and primarily covers CentOS-specific issues.

3. Install Media and sha1sums

• The installation kit is split into two DVDs. DVD #2 contains additional language packs for Open Office (OOo). On x86_64, packages java-1.6.0-openjdk-src, java-1.7.0-openjdk-src, kdelibs-apidocs and tetex-doc have also been moved to DVD #2. Installs not requiring these features should run using only DVD #1.
• There are 8 CD images for i386 and 9 for x86_64.
• You can do a minimal CentOS installation using only the first CD. All package groups except Base (in Base System) must be unchecked to allow for this.

4. Known Issues

• Known issues with UOP packages can be viewed here.

• Tomcat may not start after upgrading to the latest tomcat5 packages. See the relevant bug report for more information and a possible workaround.

• There seems to be a benign warning (according to upstream) concerning task_setrlimit for some users. See these mailing list threads. (CentOS, UOP)

5. Changes

5.1. New features

• MySQL versions 5.1 and 5.5 are now available. MySQL 5.1 is only provided for assisting in upgrading MySQL 5.0 databases to MySQL 5.5. MySQL 5.1 should not be used in production environments. For upgrading to MySQL 5.5, please follow upstream's MySQL upgrade guide. If you have set a password for the MySQL root user, you will need to add a -p switch to the mysql_upgrade command to get a prompt for the password, i.e. scl enable mysql5x 'mysql_upgrade -p'. Making a backup of your database before starting the MySQL upgrade process is highly recommended.

• As a result of the above MySQL version change, there will be no more security updates for the 5.0 and 5.1 versions of MySQL (upstream notification). To continue receiving security updates for MySQL, you must upgrade to MySQL 5.5.

• A new package gcc-libraries, consisting of libraries libatomic and libitm, is now available. These libraries provide support for certain atomic operations and transactional memory.
• The packages python-dateutil and python-lxml are now part of the distribution and will probably get removed from EPEL.
• The HP cciss RAID driver has been updated to the latest version.
• CentOS 5.8 introduced a package virt-who, used for reporting virtual guest information to the subscription manager. As CentOS does not use subscriptions for receiving updates, the functionality provided by virt-who has never been used in CentOS. CentOS 5.10 no longer ships the virt-who package, and CentOS will not provide any updates to virt-who. If you have virt-who installed, please remove the unneeded package with 'yum remove virt-who' at your earliest convenience.

7. How to help and get help

As a CentOS user there are various ways you can help out with the CentOS community. Take a look at our Contribute page for further information on how to get involved.

7.1. Special Interest Groups

CentOS consists of different Special Interest Groups (SIGs) that bring together people with similar interests. The following SIGs already exist:

• Artwork - create and improve artwork for CentOS releases and promotion

• Promotion - help promoting CentOS online or at events

• Virtualization - unite people around virtualization in CentOS

And we encourage people to join any of these SIGs or start up a new SIG, e.g.

• Alpha, S390, Sparc and PPC port - help with porting CentOS to other architectures
• Hardware compatibility - provide feedback about specific hardware
• RPM Packaging - contribute new useful RPM packages
• Translation - help translating the documentation, website and wiki content

7.2. Mailing lists and Fora

Another way you can help others in the community is by actively helping and resolving problems that users come up against in the mailinglists and the fora.

7.3. Wiki and Website

Even as an inexperienced CentOS user we can use your help. Because we like to know what problems you encountered, if you had problems finding specific information, how you would improve documentation so it becomes more accessible. This kind of feedback is as valuable to others as it would have been to you so your involvement is required to make CentOS better.

So if you want to help out and improve our documentation and wiki, register on the wiki or subscribe to the centos-docs mailinglist.
