  • Constant updates so that you can sit back and relax and always have access to the latest ways to get your visitor's address book.

  • WGET-ready! Yes, you read right! OpenInviterTM is the only contacts importer supporting both WGET and cURL as methods of handling requests (since version 1.2) so now you can use it on ANY server you want without the hassle of installing libcurl!

Upgrading mySQL from 5.0 to 5.1.on CentOS 5

My first attempt was to use yum:

[root@linux /] yum info mysql
Loading "fastestmirror" plugin
Loading mirror speeds from cached hostfile
* base: mirror.sanctuaryhost.com
* updates: mirror.fdcservers.net
* addons: mirror.steadfast.net
* extras: mirror.trouble-free.net
Installed Packages
Name : mysql
Arch : i386
Version: 5.0.45
Release: 7.el5
Size : 7.3 M
Repo : installed
Summary: MySQL client programs and shared libraries.
Description:
MySQL is a multi-user, multi-threaded SQL database server. MySQL is a
client/server implementation consisting of a server daemon (mysqld)
and many different client programs and libraries. The base package
contains the MySQL client programs, the client shared libraries, and
generic MySQL files.


Available Packages
Name : mysql
Arch : i386
Version: 5.0.77
Release: 3.el5
Size : 4.8 M
Repo : base
Summary: MySQL client programs and shared libraries
Description:
MySQL is a multi-user, multi-threaded SQL database server. MySQL is a
client/server implementation consisting of a server daemon (mysqld)
and many different client programs and libraries. The base package
contains the MySQL client programs, the client shared libraries, and
generic MySQL files.


The version 5.0.77 is good, but it not last updated release, which is 5.1.40 up today, which contains an important mysql feature named
Pationing: Enables distributing portions of individual tables across a file system, according to rules which can be set when the table is created. In effect, different portions of a table are stored as separate tables in different locations, but from the user point of view, the partitioned table is still a single table.

Basically it won’t do an upgrade as the vendor has changed from being MySQL to Sun Microsystems, and as a result I have to do a complete uninstall and re-install manually, first backup your data, stop mysql service and uninstall the current installation( 5.0.45 in my case):

[root@16 /]service mysqld stop
[root@16 /]rpm -qa | grep -i '^mysql-'
mysql-server-5.0.45-7.el5
mysql-5.0.45-7.el5
mysql-devel-5.0.45-7.el5
[root@16 /]rpm -e mysql-server-5.0.45-7.el5
[root@16 /]rpm -e mysql-5.0.45-7.el5
[root@16 /]rpm -e mysql-devel-5.0.45-7.el5

Now download all the current MySQL packages you need and install all with rpm -i( links from mySQL site):

[root@linux /usr/local/bin] mkdir mysql_5.1.40
[root@linux /usr/local/bin] cd mysql_5.1.40
