What to learn about python operation and maintenance

Operation and maintenance engineers, like developers, are both IT practitioners. Many people think that operation and maintenance personnel do not need to understand development. In fact, this is not the case. The path of operation and maintenance without understanding development will become narrower and narrower. At this stage, mastering Python development has become an essential skill for senior operation and maintenance engineers. So what should you learn about Python operation and maintenance, and how can you learn it well?

Personally recommended learning route is as follows:

Basic entry:

1. Basic knowledge of Linux, basic commands (origin, composition, common commands such as cp, ls, file , mkdir and other common operation commands)

2. Basics of Linux users and permissions

3. Advanced Linux system process management

4. Linux efficient text and file processing commands ( vim, grep, sed, awk, find and other commands)

5. Getting started with shell scripts (you can learn while practicing)

Intermediate advanced

Intermediate advanced level requires an in-depth study of upper-layer applications and services after fully understanding the principles and basic knowledge of Linux. When it comes to services, it definitely involves network-related knowledge, which requires time to learn.

1. TCP/IP network basics (approximate knowledge of CCNA and NP is enough)

2. Commonly used services in Linux enterprises (such as dns, http, ftp, mail, nfs, etc.)

3. Linux enterprise-level security principles and prevention techniques (system performance/security, security threat models and protection methods

4. Encryption/decryption principles and data security, system service access control and service security Basics

5. iptables security policy construction

6. Shell script advancement (mainly combining some applications and writing some cases)

7. Introduction to MySQL application principles and management (Be able to manage and build a personal blog site)

After learning here, the basic skills mastered are enough, and I can already do some basic operation and maintenance work and simple maintenance.

Advanced improvement

1. http service proxy cache acceleration (mainly learning varnish and nginx cache systems, and having some knowledge of CDN.)

2. Enterprise Level load cluster (mainly to learn nginx, haproxy, lvs, you must master the main knowledge and have a clear understanding of the load balancing algorithm)

3. Enterprise-level high-availability cluster (which requires keepalived, heartbeat, etc. In-depth explanation)

4. Detailed explanation of operation and maintenance monitoring zabbix (mainly monitoring systems such as zabbix, cacti, nagios, etc., zabbix is ​​more commonly used now)

5. Operation and maintenance automation learning ( You need to learn how to use some open source operation and maintenance automation tools such as ansible, puppet, cobbler and other operation and maintenance automation tools)
