Getting started with VPS.

[drachma]

Guide to VPS:

Logon to your WHM panel
https:// your_ip:2087 -- use your root/password

Update your cpanel to the latest 'Release' version using the automated scripts.

If you're using your own Nameservers:
* add- ns1.yourdomain.com, ns2.yourdomain.com and associated IPs to your domain registrar (i.e. godaddy.com)
* modify WHM-Hostname (i.e. myserver.yourdomain.com), nameservers

Follow security guidelines

Possible Trojan - /usr/bin/pstruct
Possible Trojan - /usr/bin/s2p
Possible Trojan - /usr/bin/splain
Possible Trojan - /usr/bin/xsubpp
Possible Trojan - /etc/cron.daily/logrotate
Possible Trojan - /usr/bin/curl
Possible Trojan - /usr/lib/libcurl.so.3.0.0
Possible Trojan - /usr/sbin/pureauth

Compile Apache, PHP + mods you want
Add eaccelerator - http:// eaccelerator.net/wiki/InstallFromSource
**my modifications
* mkdir /tmp/eaccelerator, chmod 777 /tmp/eaccelerator
* edit /usr/local/lib/php.ini and add

zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20020429/eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

phpsuexec + eaccelerator/APC/or any php accelerator will not to work...keep this in mind

Add zend optimizer - via SSH su/root run /scripts/installzendopt, follow instructions

Add Cpanel/WHM package + accounts!

Good php scripts for monitoring:
vpsinfo www. labradordata.ca/home/13
loadavg www. labradordata.ca/home/37

If your log files are getting out of control, it's probably because you need to tweak settings in /etc/logrotate.d/httpd and /etc/logrotate.conf to accomodate for cpanel log files
check out www. duntuk.com/node/59

Please install the following modules to your apache. I prefer manual compile vs cpanel's plugins
www. modsecurity.org/ (mod_security) (for apache 1.3.x please install (PCRE)
www. pcre.org/ then compile
modsecurity.org/documentation/modsecurity-apache/1.9.3/html-multipage/02-installation.html Rules from
www. gotroot.com/tiki-index.php?page=Setup+of+mod_security (gotroot)
www. zdziarski.com/projects/mod_evasive/ (mod_evasive)
**Don't forget to change your /usr/local/apache/conf/httpd.conf file to reflect these 2 mods.

I've had issues installing APF firewall or ConfigServer Security & Firewall due to the VPS kernel. I've made settings in those configs to reflect VPS however nothing has worked yet. If anyone has an idea please post.
