Students who are willing to develop into the IT Internet see one of the most common occupations as Linux operation and maintenance engineers. So what does this Linux operation and maintenance engineer do? If you want to enter the field of operation and maintenance, you should first understand what linux operation and maintenance engineers do.

By name, Linux operation and maintenance engineers can do according to the names on the recruitment website are: large and medium-sized network engineer or network administrator; Linux/Unix network engineer, system integration pre-sales engineer; network scheme implementation engineer, after-sales technical support engineer, mail server administrator; network security engineer, SQL database administrator; website maintenance engineer; network security consultant PHP enterprise station administrator; Internet website administrator, forum erection administrator.

From the direction of Linux:

1. Linux system, network, service, cluster, website, network application direction, responsible for Web application server, Mail application server, middleware or J2EE server

2. Embedded development, Linux application, kernel driver development, responsible for the development of CumberCraft + system program and embedded Linux under Linux

3. Databases under Linux, such as MySQL and Oracl.

How is the money of Linux operation and maintenance staff? Data that you can often see on recruitment websites:

Junior Linux operation and maintenance engineer, monthly salary 10K~14K

Intermediate Linux operation and maintenance engineer with a monthly salary of 14K ~ 20K

Senior Linux operation and maintenance engineer with a monthly salary of 20K +.

Here, it is only roughly divided into three levels of junior high school. It can be seen from the basic income that the entry level is basically 10K. Whether you are working in a small-scale company or a first-tier Internet company like BAT. After entering some enterprises, you will find that enterprises particularly like to use linux, why use Linux? Many students think that Linux is better and more stable, but it is not.

Why enterprises use them is actually for the purpose of saving costs and creating value. The software investment and service investment of the server operating system is quite large, which is one of the reasons why open source free CentOS and FreeBSD are becoming more and more popular. Enterprises are always constantly reducing costs and improving revenue. Whether it is software cost or hardware cost, personnel cost is also a trend of continuous compression. Because the operation and maintenance costs of enterprises are often very high, the IT system of an enterprise is composed of three parts:

The first part is the enterprise server and personal computer, etc.

The second part is the network equipment such as switch, Hub, etc.

The third part is the enterprise business application system, such as ERP system, HR and CRM system and so on.

According to the definition of the scope of IT operation and maintenance, the main contents can be summarized as follows: desktop system maintenance, network system maintenance, network security system maintenance, server maintenance, software system maintenance, computer room environment maintenance, IT fixed assets management services. The cost of IT operation and maintenance is often the weakest link in enterprise management, and the operation and maintenance cost is also increasing year by year.

Above, we have analyzed the situation and difficulties of the enterprise, and we just want to tell the students a truth: as a qualified Linux operation and maintenance personnel, we should not only make the enterprise realize the importance of operation and maintenance, but also make the enterprise realize the benefits brought by operation and maintenance. technically, you should become an expert and be good at communication in your work, especially cross-departmental communication. The degree of understanding determines the height of your income.

There is no doubt that the first-tier cities are higher than the second-tier cities, which is also related to income. According to the geographical division, the operation and maintenance of Linux/unix system is suitable for Beijing, Shanghai, Shenzhen and Guangzhou, while the development is more suitable for Hangzhou and Nanjing.

Compared with traditional industry positions, Linux operation and maintenance in first-tier and second-tier cities, the starting point of entry income is higher, but to achieve income growth, but also combined with the platform, continue to hone their own technology, become experts in Linux operation and maintenance.

If you are a beginner of Linux, the work must be very complicated and unsystematic when you first get started, so don't pay too much attention to the issue of treatment at this time. From the basic work familiar with a variety of services, network knowledge, it is best to be able to train to write a variety of automated scripts, and automated deployment. Review the knowledge you have learned before, such as data structure, algorithm, TCP/UDP, although it is very boring, but these things will enable you to climb another tall building in the future. It is necessary to pay attention to do not cast a wide net after laying a good foundation, which is a waste of energy, and it is best to go deep into a system level of longitudinal learning. If you are completely self-taught to enter the field, when you find it difficult, the best way is to find a good platform, and a team with rich practical experience in this field, join them. Because knowledge is endless, the more you know, the less you learn.
