- How to prevent hackers from attacking corporate systems?
- As enterprises' digital transformation and information construction become more and more in-depth, more and more sensitive data are stored and transmitted in enterprise systems, so the security of enterprise systems has become more and more important. Hacker attacks will not only cause economic losses to the enterprise, but also cause a devastating blow to the enterprise's reputation and user trust. Therefore, companies must take necessary precautions to prevent hackers from attacking corporate systems. 1. Strengthen network security awareness. Enterprises should strengthen network security awareness, educate employees on network security, popularize network security knowledge, and improve employees’ understanding of network security.

- Why should I spend the time before retirement struggling with the operation and maintenance knowledge automation system?
- My team has been doing system optimization since 2003. At the invitation of HPSERVICE, I joined their Haier system optimization team in 2003 and was responsible for the optimization of Oracle database. This was my first time to participate in the optimization of a large-scale system. Even at that time, I didn't know where to start optimizing a large-scale after-sales service system. I went to Qingdao to participate in this optimization project with a book by Levi's. Through this project, I gained a preliminary understanding of the optimization of Oracle databases. Later, I helped HP complete the performance evaluation of the CAF platform used in Huawei's SCM system, and recommended to the decision-makers to stop the project in time to avoid greater waste of funds, because the project could no longer be optimized. back

- Having worked in operation and maintenance for more than ten years, there have been countless moments when I felt like I was still a novice...
- Once upon a time, when I was a fresh graduate majoring in computer science, I browsed many job postings on recruitment websites. I was confused by the dazzling technical positions: R&D engineer, operation and maintenance engineer, test engineer... During college, my professional courses were so-so, not to mention having any technical vision, and I had no clear ideas about which technical direction to pursue. Until a senior student said to me: "Do operation and maintenance. You don't have to write code every day to do operation and maintenance. You just need to be able to play Liunx! It's much easier than doing development!" I chose to believe... I have been in the industry for more than ten years , I have suffered a lot, shouldered a lot of blame, killed servers, and experienced department layoffs. If someone tells me now that operation and maintenance is easier than development, then I will

- systemd log maintenance guide (with examples)
- If your Linux distribution supports systemd, it will collect logs from all processes and applications on the system every second starting from boot time. All these log events are managed by systemd's journald daemon. journald collects all logs (information, warnings, errors, etc.) and stores them as binary data in disk files. Since the log is kept on disk and collected every second, it takes up a huge amount of disk space; especially for older systems and servers. For example, on one of my test systems that has been running for about a year, the log files are gigabytes in size. If you manage multiple systems and servers, it is recommended that you

- 1. Overview Compared with ad-hoc, playbook is a completely different way of using ansible, similar to saltstack's state file. Ad-hoc cannot be used permanently, playbook can be used permanently. A playbook is a list consisting of one or more plays. The main function of a play is to dress up hosts that have been previously grouped into a group into roles that have been defined through tasks in ansible. Fundamentally speaking, the so-called task is nothing more than a module that calls ansible. Organizing multiple plays into a playbook allows them to be combined to complete a certain task according to a pre-arranged mechanism.

Nginx will inevitably have some loopholes, and Nginx is also constantly undergoing version iterations, so we need to prevent the outside world from obtaining our Nginx version when accessing externally. Reduce some attack risks caused by version exposure. (Upgrading to the latest version in time will provide higher security.) This article introduces how to hide the version number of our Nginx to avoid external attacks. 1. How to check whether the Nginx version of your own server is hidden?

- From monitoring to diagnostics: the power of data
- Monitoring and diagnosis have always been two very important links in database operation and maintenance. In the traditional operation and maintenance model, monitoring and diagnosis are people-centered, so the collection of indicators and data must also focus on people. Monitoring data needs to be viewed by people. Through human viewing, abnormalities in the monitoring data or areas worthy of vigilance can be discovered. DBAs of different levels can see different levels of risk from the data. Because it requires people to see it, there should not be too many indicators displayed, otherwise the monitoring personnel will be dazzled. In fact, the number of key indicators in the above picture is too many to monitor. For monitoring that relies on people, brief and intuitive indicator display is very necessary. For databases, only focusing on three or five key indicators can better achieve manual monitoring.
