In this article Xiaobian for you to introduce in detail "what is the method of caching nscd in Linux system", the content is detailed, the steps are clear, and the details are handled properly. I hope that this article "what is the method of caching nscd in Linux system" can help you solve your doubts.

The main function of nscd is to speed up the parsing of DNS. It is a local caching service. It is recommended to enable it in private networks where APIs are called frequently.

When nscd's hosts caching service is enabled, each internal interface request will not initiate a dns resolution request, but will directly hit the nscd cache hash table to obtain the corresponding server ip address, which can reduce the response time of the interface when a large number of internal interface requests are made.

The nscd cleanup cache command is as follows:

[root@localhost ~] # nscd-I hosts if nscd is not installed, it needs to be installed manually

\ 1. Install nscd

[root@localhost] # yum-y install nscd\ 2. View status and start commands

[root@localhost ~] # systemctl status nscd # View status systemctl start nscd [root@localhost www.linuxidc.com] # systemctl start nscd # start nscd\ 3. After starting the nscd service, clear the cache

[root@localhost ~] # nscd-I hosts in many cases, after enabling nscd, you will find that the hit rate has been 0. The reason is that many linux services use the direct access mode to read the cache, and the direct read mode performs better, but it cannot be counted because it does not go through the daemon.
