This article introduces the relevant knowledge of "how to maintain the security of Linux server". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Although the Linux server is relatively more stable and secure than the Windwos server, we should also pay attention to its security. Today, the editor shares how to maintain the security of the Linux server in two aspects.

First, realize the planning of zoning.

The partition planning of Linux operating system is different from that of Microsoft operating system. The latter has little impact on its performance. However, the partition planning of Linux operating system is different, which has a great impact on the performance of the server. In fact, I like to compare the partition of the Linux operating system to the tablespace planning in the Oracle database. The two of them are similar. The quality of the planning will directly affect the performance of its operation. The impact on subsequent performance is significant if you only need to make some minor adjustments at deployment time. If I use the Linux operating system as a server, I will consider placing some special directories on different partitions, which will help to improve the performance and security of subsequent servers. For example, the / tmp directory and the / home directory can be placed on different partitions; for example, the / var and / usr directories can also be placed on different partitions. If hardware conditions permit, it is best to place the / var directory on a separate partition. Because these directories have their special uses, and they are used more frequently. If they are placed separately, the efficiency of data reading can be improved, and the space contention between each other can be reduced.

In addition, swapping partitions also require special attention. Swap partitions under the Linux operating system are like virtual memory under the Windows operating system. However, there is a big difference between the two under the follow-up adjustment. For example, under the Windows operating system, if there is not enough virtual memory, you can adjust it in the system properties and advanced pages. And even if the virtual memory is adjusted later, the execution performance of the subsequent increased space is the same as the original space. In the Linux operating system, if it is later found that the lack of virtual space affects the performance of the application, and even affects the installation of the application.

Second, shut down unwanted services

Like the Windwos system, the system starts a lot of services after installation. Some of these services are necessary for the operating system or application to allow. But some do not need to be started. On the contrary, it will bring some security risks to the operating system. For this reason, the system administrator needs to see the services it is running after deploying the Linux operating system. Then shut down some unwanted services as needed. For this reason, the system administrator should have the ability to determine which services are necessary and which can be turned off. At this time, the system administrator can refer to the instructions of some applications and make a judgment based on his own work experience.
