If you are here then you probably already know how to install PHP 5.2 on your CentOS 5.2. One of the ways would be to use a third-party repository like Remi. Here is a good article about how to use it.
If after trying to use a third-party repository to install PHP 5.2 you get a “Could not find update match for php” error then there is a big chance you have a priorities package installed in your CentOS distribution and some repos are not properly configured priorities wise: basically your third-party repo does not have a chance to look for PHP 5.2 binaries because other (default CentOS) repositories get priority.
The easiest way to fix the problem is to temporarily disable the priorities package.
Edit the priorities file:
sudo vi /etc/yum/pluginconf.d/priorities.conf
and set “enabled” equal to 0
To check if the priorities package is installed on your system run:
rpm -q yum-priorities

- Install geoip via yum:
yum install geoip geoip-devel
- You also might want to download database with ip addresses from Maxmind website and place it in
/usr/share/GeoIP (which is a default location of geoip upon installation).
- Install PECL extension:
pecl install geoip
- Add
extension=geoip.so to your /etc/php.ini
- Restart apache:
/etc/init.d/httpd restart

I have decided to say goodbye to the shared hosting once and for all and finally moved all of my personal sites and blog to a virtual private server (VPS) running CentOS 5.2 and Plesk.
I didn’t do this because I was unhappy with my former shared hosting provider as they had good up-time and the support was fast and helpful. I did it because I needed greater access to my hosting then shared hosting can provide; e.g. tweaking the server, installing custom software and controlling the versions of software installed on the server (e.g. symfony and subversion).
The switching process took a little more than a week. A little slow I know, but it wasn’t a full time gig. But at last I can announce that my switchover to a VPS set-up is complete.
Now here’s hoping my new host does not upset me with frequent downtime 
Just in case you were curious, my shared hosting was with A2hosting and I highly recommend them if you are after shared hosting. They also offer VPS hosting but I have not tried their offering yet.

Edit your /etc/exim/exim.conf file
Add to Routers section
send_to_gateway:
driver = manualroute
transport = remote_smtp
route_list = * mail.optusnet.com.au
If your SMTP server requires authentication you also need to do this:
Add to Authentication section
- Enable authentication for hosts host1.example.com, host2.example.net and host3.example.org (you have to list all smarthosts where Exim may authenticate users):
remote_smtp:
debug_print = "T: remote_smtp for $local_part@$domain"
driver = smtp
hosts_try_auth = host1.example.com:host2.example.net:host3.example.org
- SMTP-Auth with the name “usera” and the password “secrect” (cram_md5 encrypted):
cram_md5:
driver = cram_md5
public_name = CRAM-MD5
client_name = usera
client_secret = secrect
- SMTP-Auth with the name “usera” and the password “secrect” (plaintext):
plain:
driver = plaintext
public_name = PLAIN
client_send = ^usera^secrect
- Or get name, password and send method automatically from my config-file:
cram_md5:
driver = cram_md5
public_name = CRAM-MD5
client_name = "${extract{auth_name}{${lookup{$sender_address}lsearch{/etc/exim/smtp_users}{$value}fail}}}"
client_secret = "${extract{auth_pass}{${lookup{$sender_address}lsearch{/etc/exim/smtp_users}{$value}fail}}}"
plain:
driver = plaintext
public_name = PLAIN
client_send = "${extract{auth_plain}{${lookup{$sender_address}lsearch{/etc/exim/smtp_users}{$value}fail}}}"
Add to Transports section
remote_smtp:
debug_print = "T: remote_smtp for $local_part@$domain"
driver = smtp
hosts_try_auth = your.smtp.server.com

This is a quick guide (by jervis) on how to do an install and basic setup of exim on CentOS. This is not meant as a fully inclusive guide but it will get you on the way. Following this you should get a working exim install.
I will assume you have built a CentOS 4 / 5 Server, have yum working and have logged in as root.
yum update
Install exim and mail switching tools
yum install exim
yum install system-switch-mail
Switch your MTA & set exim to start on boot
system-switch-mail
service sendmail stop
service exim start
chkconfig exim on
chkconfig sendmail off
Add a root alias, eg: “root: me@example.com”
vi /etc/aliases
You may also wish to add some config to your routers section like this, if you want to relay through a smart host.
vi /etc/exim/exim.conf
Then add this before the “dnslookup:” section.
to_smart_host:
driver = manualroute
domains = ! +local_domains
transport = remote_smtp
route_list = “* mail1.example.com:mail2.example.com;”
Restart exim
service exim restart
To test, send an email
echo “test” |mail -s “$HOSTNAME” me@example.com
Then you can flush the Exim Que and watch the log like this
exim -qff ; tail -f /var/log/exim/main.log
Good luck!

If you, like me, got to the point where you have Mindquarry installed on your linux distribution together with Java Runtime but still can not run Mindquarry successfully and the error says something like:
“you need to install mod_perl2 and LWP::Agent” then this post is for you.
To install LWP::Agent: Download it and install by placing into the directory accessible via global PATH variable.
To install mod_perl2: execute in your terminal yum install mod_perl and make sure that the version you are installing is >2.x

If you are using Bash as your terminal, here’s what you need to do:
Edit ~/.bash_profile by adding the following (if you want to set TESTVAR variable to “This_is_a_value” value)
export TESTVAR=This_is_a_value

Install software needed by VMware Tools
Note: you need to boot the 1-1 kernel from grub for this to work.
- Install packages to build the kernel modules:
yum install gcc kernel-devel
- Check the running kernel matches the kernel headers:
uname -r # running kernel
rpm -q kernel-devel # installed kernel headers
- If the two versions do not match, run:
yum -y upgrade kernel kernel-devel
reboot
- Find out where the kernel headers are (you may need this later):
ls -d /usr/src/kernels/$(uname -r)*/include
Prepare and install VMware Tools
Note: this guide is for you If you are running the VM inside VMware Workstation 5.5+
- From VMware Workstation: go to VM> Install VMware Tools
- From the VM: mount the virtual cd drive:
mount /dev/cdrom /mnt/
- Extract VMware Tools to:
/tmp/tar -C /tmp -zxvf /mnt/VMwareTools-5.5.3-34685.tar.gz
- Unmount the virtual cd drive:
umount /mnt
- Now run the installer:
cd /tmp/vmware-tools-distrib
./vmware-install.pl
- When asked “Do you want to run vmware-config-tools.pl?”, answer “Yes”.
