Disable unnecessary system services in Linux to speed up

Article Title: disable unnecessary system services in Linux to speed up. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Linux System in/etc/rc. d/init. d defines a lot of system services to provide to users. By default, most of these services are started randomly, but many services are generally not required, or, if you do not configure it, it does not work at all, but because it is set to random start, after the kernel is loaded into the memory and starts to run, it will take time to start the corresponding processes of these services to greatly reduce the boot speed. Therefore, you can close these services to speed up the boot speed.

Most of the system services of different GNU linux versions are the same, but there are also some minor differences. Generally, about 50 services are provided.

Taking redhat9 as an example, most of the following system services can be shut down:

Cron (depending on the situation, sometimes required)

Anancron

Apmd

Atd

Autofs

Cups (with a printer)

Gpm

Isdn

Kudzu

Netfs

Nfslock

Pcmcia

Portmap

Rawdevice

Rhnsd

Sendmail (you can disable the email server)

Ipsec (without configuration, it does not provide security at all)
