Ability to write Shell (master for in, case, while statement)

Ability to deploy Contab

Ability to deploy iptables

Ability to expand disk capacity

Ability to backup multiple RAID drives

Mastering the statement that sends e-mail under Linux

Python/c/ruby and other language basic programming ability, will be one of them, but not to be satisfied with writing a small game, write a crawler, write a few numbers back and forth to calculate a simple program, but in actual production can actually use. For example, in the thousands of data to pick out the required data, can separate the required data, can be combined with the file operation, really is to achieve the purpose of automated operations.

Zabbix/nagios installation and basic configuration, will use them to send mail/alarm, can according to different requirements independent write monitoring script better.

HTTP basic knowledge (now requires to have an understanding of HTTPS), can know the principle of caching, TCP/IP principle, TCP header, UDP Baotou and so on knowledge.

Master the principle of DNS, and hands-on DNS server experience is better. Let's take a look at CDN knowledge.

Cobbler: This is a tool for installing servers in batches based on IP addresses. The technology that will PXE the network boot server. To install the CentOS system in bulk, see http://kerry.blog.51cto.com/172631/648430/.

Puppet: This is a version of the software that guarantees each server based on the IP address/hostname.

The next is to be able to independently read the source code writing module, with GitHub background.

Operations Engineer's talent tree up to the point is the DBA (Big Data analysis direction), Senior Ops supervisor and System architect (I personally think this is the ultimate talent), these are basically Daniel's level, the time in Beijing monthly salary 50,000, stock dividends, year-end awards take a two hundred thousand or three hundred thousand is not a matter, strive to do before the age of 40 , then it will be a lot easier in the next few years.
