Unix (CentOS Virtualizor) with CDN server for website.
I'm looking currently for some good system admin who can work under CentOS 6 with knowledge for Firewalls/Iptables.
We did have VPS ex:
VPS No.101 xx.xx.xxx.59 mysql.sameerbook.com (MySQL Master Database - Only have connection from VPS 102).
VPS No. 102 xx.xx.xxx.58 www2.sameerbook.com (Website Files only - Accepting connection from VPS 104 + 103).
VPS No. 104 xx.xx.xxx.57 lb.sameerbook.com (Nginx VPS for filtering & Optimizing the visitors request).
VPS No. 105 xx.xx.xxx.56 www3.sameerbook.com ( VPS for Images/png only ).
- re-design or work in the same plan for our VPS's (CDN Network) and make sure all it's firewalled and secure from any kind of SYNFLOOD.
- make sure to run a backup system in our external HD for the most important website files, also for specific dirs from other VPS's.
- Optimize the Apache with MySQL and if installing Varnish with special customization that would be good.
- Measure and calculate maximum memory usage in apache for our running tasks ( apache requests ) in VPS 102 and check the nginx configuration and make sure to optimaize it very well.
Please make sure to start on the optimization & installaing varnish tonight
