I’ve been to server rooms, power control stations but a data center feels different.

Like in those movies, multiple sliding gates with biometric access control, engineers on shift monitoring screens, plenty of close circuit cameras, air-conditional room, tons of cables running under the floor, rows after rows of racks of servers and wires.

A $2k server rack is slide into place, power and ethernet cables attached. Monitor, keyboard placed on a trolley is rolled near for connection like a life support unit. The power button pushed, the small but powerful fans hums along with the symphonies of fan noise in the data center.

The network installed CentOS, the free enterprise Red Hat Linux, runs the server. Due to my personal discrimination against RH since version 6, I had to adapt to its environment.

/etc/sysconfig/network-scripts was the place where ip, dns addreses and network configurations was. system-config-securitylevel configures the firewall, yum installs, manages and updates the system. Guides exist online. Some other commands to configure and control services. I also discovered write and talk. The rest is usual linux.
