Today, I would like to talk to you about how to carry out linux operation and maintenance, many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

Generally speaking, Linux operation and maintenance engineers are easier to master than development, which requires higher mathematical ability, because in the later stage, algorithms will become the ceiling of many people, and Linux operation and maintenance engineers will be easier to learn. They are all hands-on disciplines that practice commands, installation, configuration and services. And for fresh graduates, it is very easy to learn, because in the school curriculum, there are many basic skills needed by operation and maintenance: operating system, network, database, Linux and so on. For people who change careers, Linux operation and maintenance engineers are more interesting and easier to use, especially if girls want to learn IT,Linux operation and maintenance is the first choice, easy to use, high salary, and easy to work in the future, because there will be a lot of men to help you solve problems.

To become a qualified OPS engineer, you need to master a lot of skills. Linux OPS engineers pay attention to breadth. Here are the learning contents recommended by Linux cloud computing engineers:

1. The basic door of Linux system-the basic knowledge of Linux, the use of commands, as well as core knowledge points such as users and permissions.

2. Linux system management and advanced-Linux management from processes, resources, tasks, components, software packages, disks, etc.

3. Linux Enterprise Common Services-Enterprise Common Services such as DNS, FTP, Http, mail

4. Linux enterprise security principles and prevention techniques and network and security-Linux security architecture, security threat model, encryption, decryption and other principles, common attacks and prevention segments

5. Shell programming gate and advanced-basic usage and advanced Shell script, from basic to proficient, you need to learn some common enterprise script usage.

6. MySQL application principle and management door-Mysql installation, management, authorization, addition, deletion, modification and search

7. Http service proxy cache acceleration-http level protocol application, cache, web service nginx

8. Enterprise load cluster-the application of enterprise layer 4 load balancer LVS, layer 7 load balancer nginx and haproxy

9. Enterprise-level available clusters-the principle of available clusters, the realization of available clusters based on keepalived, as well as master-slave high availability and dual-master

10. Operation and maintenance monitoring zabbix- enterprise monitoring system and zabbix stream open source monitoring system function and architecture

11. Cloud computing operation and maintenance automation-ansible, puppet and other operation and maintenance automation solutions

12. WEB service architecture-WEB service architecture, JSP architecture, tomcat, CDN, cache principle, pressure testing, evaluation

13. Type interconnected cluster architecture and actual combat case-LB cluster: nginx, Haproxy, LVS HA cluster, dynamic and static separation

14. MySQL DBA actual combat skills and optimization-database parameter optimization, database table division, backup scheme, data recovery strategy, master-slave replication, read-write separation, connection pooling and sharding technology, MHA, etc.

15. Enterprise cloud computing Openstack-Keystone, Glance, Nova core components, network modules, block storage services, etc.

16. Enterprise data Hadoop operation and maintenance practice-column database HBase basic principle, installation and configuration and its response, Zookeeper cluster construction hadoop to achieve Namenode

17. Enterprise Virtualization KVM practice-KVM Environment: installation, configuration and response of KVM

18. NoSQL enterprise applications-Nosql applications, such as redis, MongoDB replication, cluster level applications

19. Enterprise Log Collection system ELK practice-massive data Log Collection system Elasticsearch+Logstash+kibana Application

20. Sustainable Integration-Jenkins+github Enterprise Application

21. Virtualization Container Docker-Linux lightweight Virtualization Docker, Docker principle and installation, configuration and Application

22. Enterprise K8S practice-component functions, installation, configuration, enterprise application scenarios and common fault analysis

23. Linux system tuning practice-comprehensively explain Linux system tuning from memory, CPU, process scheduling, disk IO, network parameters, etc.

24. Python programming basic gate-python installation, logic judgment, module use, etc.

25. Personal comprehensive ability improvement-expression ability, teamwork ability, executive ability, competence, etc.
