What self-starting services do I need to keep after Linux installation?

As with Windows, Linux servers run with useless software services by default, which consumes a lot of system resources and has security implications, so it is generally recommended to shut down. So, what do Linux hosts need to boot from at work?

After the Linux system is installed, it is necessary to keep the boot service with 5:

? SSHD: The remote connection to the Linux server is used, so it must be turned on, otherwise it will not be able to provide remote connection services.

? Rsyslog: Log related software, which is a mechanism provided by the operating system, the system daemon usually uses the Rsyslog program to write various information to the various system log files.

? Network: When the system starts, if you want to activate or turn off the various interfaces, you can consider turning it on.

? Crond: A task plan for periodic execution of systems and User Configuration. Open when needed. It is almost a software that must be used in operation and maintenance work.

? Sysstat:sysstat is a software package that contains a set of tools to monitor the performance and efficiency of the system, which is useful for collecting system performance data, such as CPU usage, hard disk and network throughput data, and the collection and analysis of these data can help to determine whether the system is functioning properly.

The main tools for Sysstat package integration are:

? The Iostat tool provides data on CPU usage and hard drive throughput efficiency.

? The Mpstat tool provides data related to a single processor or multiple processors.

? The SAR tool collects, reports, and stores information that is active on the system.

The above 5 services are recommended to be retained after the installation of the system start-up service, but also all the production server must keep the start-up service. In the future, the corresponding self-starting services can be adjusted based on the server's business usage scenarios.

Hope that through the sharing can help the needs of the pot friends. Linux is now popular with internet companies and wants to stand out from the many IT workers, requiring advanced technology and learning to add value is essential. The way of learning is your insistence. Old boy Education Linux cloud Computing Operations course, 10 years of technical precipitation, put an end to paper, the whole enterprise real case combined with theoretical teaching, want to learn more about the Linux cloud computing operations knowledge, can pay attention to the old boy education.
