Anonymous users2024-02-07The main job of a Linux O&M engineer is:
1.Log in to the system every day to check the load of the system and check whether there are error logs or alarm logs.
2.Operating system troubleshooting.
Analyze the cause of the alarm or error based on the operating system fault log to solve the problem and ensure the high availability of the operating system.
3.Server status confirmation.
In addition to running the operating system, some applications or databases will inevitably be installed on the server, and the operation and maintenance engineer needs to check whether the application or database running on the Linux system is normal every day.
4.Backup. Generally speaking, as long as the database is backed up by itself, as long as the backup policy is formulated for the database, it will back up by itself, and you only need to monitor whether the backup task is executed.
5.Server tuning.
This requirement is relatively high, as the state of Linux will decrease with the growth of use time, and the operation and maintenance engineer has the ability to optimize the performance of the operating system and database to ensure that the system is in an optimal state.
Generally speaking, the work of O&M engineers is mainly monitoring, and they will only deal with problems when they occur, which is usually very easy. I'm in charge of the operation and maintenance of six servers for three information systems, which is quite easy.

Anonymous users2024-02-06What do you say about this cave attack question? Very ambiguous. Whether it's good or not, first of all, you need to understand, learn, and then work, only in the work, will you really understand whether Linux operation and maintenance is good or not, everyone's work level is different, and the view on this issue is different, in fact, it depends on your understanding of work, if you work well, then you must say that Linux operation and maintenance is easy to do, if you don't work well, don't make money, you may abandon this industry!
In fact, from the perspective of the industry, Linux operation and maintenance is a good job!
Choosing Linux is the trend of the times.
Linux technical support is extensive, open-source, stable, and efficient, providing platform support for big data, cloud computing, and the Internet of Things, which will never go out of style.
Linux O&M salary is relatively high!
Linux O&M is an increasingly popular industry, and your salary may only be seven or eight thousand at the beginning, but don't worry, it's good later, and the longer the working life of Linux O&M, the more popular it is. Don't worry, it's a youth meal!
Okay, I'm sharing a learning roadmap for the overall knowledge of Linux O&M!
Linux Learning Roadmap.

Anonymous users2024-02-02You have to do development, you have to update the content.
I have been engaged in the operation and maintenance industry for more than four years, in addition to the service department and then the operation and maintenance department is the most relaxed, you can try to change companies on the hour, you can try to change companies!
1. Industry advantagesThe development of communication technology provides a new space for the development of network operation and maintenance engineers. With the implementation of 5G standards and technologies such as the Internet of Things, cloud computing, and big data, a large amount of new data will flood to data centers. These development opportunities not only exist in the traditional field of data communication, but also include new fields such as "cloud computing, big data, Internet of Things, artificial intelligence" and so on. >>>More
