I. the development direction of basic network management

1. You can learn from CCNA (or equivalent certified) and develop into a network engineer.

CCNA is recommended for the following reasons:

1) there are many kinds of simulators, mature technology, many types of routes and switches, relatively few H3C and Huawei simulators, and few optional routes and switches.

2) there are many mature professional training institutions in Cisco.

3) you can learn from Cisco exclusive coordination, such as EIGRP, HSRP, etc.

4) it is recognized by Cisco all over the world that H3C may only have china (joke)

two。 You can learn the basics of linux and develop in the direction of operation and maintenance

3. You can learn programming, such as php and asp.net. It is not recommended to learn java directly, because it is more difficult to use 0 directly than the former two.

Second, the development direction of intermediate network management.

1. Develop towards CCNP

Understand:

EIGRP, OSPF, redistribution, BGP, × × (several commonly used ipsec,site to site,move × × ×, etc.), MPLS, IPV6

Switching security, AAA authentication, IPS, MLS, Multicast, VoIP, QOS rectification, frame Relay, etc.

two。 Develop in the direction of operation and maintenance (mainly websites)

1) basic knowledge of CCNA is required (may not be verified)

2) have windows and linux related programming foundation, can read, can configure and write simple programs php,asp.net and java choose one or two

3) be familiar with linux:

a. Basics:

There are about 100 common commands in ①.

② must linux three musketeers grep,sed,awk, regular expression, this is must be the killer's mace, the work efficiency is very high, the interview is also very good

③ linux system startup process, directory structure, common configuration paths, file properties, link knowledge, directory permissions, user management, disk management, network foundation (with IP setting routing, etc.)

④ linux basic network service, linux core network service, linux website cluster service

⑤ database mysql master (preferably oracle) master-slave, cluster, optimization, redis, memcached cache

b. Security:

System security, website security, * processing, database optimization (not used by large companies), network security

c. Architecture

Familiar with the common architecture and troubleshooting of mainstream websites, such as LAMP,LNMP

d. Other technologies

LVS+keepalived, iptables, svn (version control), open***, openswan, haproxy,

KVM virtualization, quid (cache proxy), heartbeat, monitoring (nagios, zabbix), etc.

3.windows direction

1) basic knowledge:

Windows common server building, such as FTP,asp.net website, domain, DNS knowledge (some), data synchronization

2) understand the simple programming of asp.net

3) understand database, MSSQL, preferably oracle, master-slave, simple optimization, memcached cache

3. Program development (website-based)

Familiar with mainstream website architecture (different programming languages have different architectures), tiering (some require MVC), js, jquery, AJAX, memcached (some not required),

Factory pattern (some are not required), familiar with one of the programming languages (php, asp.net,

4.DBA

Mainly data optimization, database construction, database development and so on.

5. Safety direction

Network security, website security, server security (this kind of work is boring, watching data analysis or * testing all day)

Knowledge that may be used: professional skills (including programs and explanations) + being a person

III. Advanced technology

Become an expert, manager, or director in a field

Knowledge that may be used: professional skills (superposition of knowledge), management, life, sales, programming and tender preparation and explanation

Superposition of knowledge: improve your knowledge when you are professional

Such as:

Operation and maintenance on the basis of development, called operation and maintenance development, operation and maintenance development is not equal to development, you do operation and maintenance, when the operation and maintenance development is the superposition of your operation and maintenance capabilities.

If you do operation and maintenance and do php non-operation and maintenance development, it is not a superimposed process, unless you develop in the direction of CTO.

Development, operation and maintenance, on the basis of development, do development-related operation and maintenance, such as the collocation of the environment, development troubleshooting.
