Linux Resource Limits KodeKloud Engineer Task Success

Question : On our Storage server in Stratos Datacenter we are having some issues where nfsuser user is holding hundred of processes, which is degrading the performance of the server. Therefore, we have a requirement to limit its maximum processes. Please set its maximum process limits as below:

a. soft limit = 80

b. hard_limit = 92

Please Note:-  Perform the below commands based on your question server,  user name & other details that might differ as per the task.

Solution:  

1. At first login to one storage server  &  Switch to the root user 

thor@jump_host /$ ssh natasha@ststor01 The authenticity of host 'ststor01 (172.16.238.15)' can't be established. ECDSA key fingerprint is SHA256:goyzCLJtN5R0K2ifNzlG1NoZGKKhvwu2Ub1r1eyVYcc. ECDSA key fingerprint is MD5:d1:90:fd:eb:71:c9:0f:71:06:1d:b5:bd:a2:b2:20:2d. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'ststor01,172.16.238.15' (ECDSA) to the list of known hosts. natasha@ststor01's password: [natasha@ststor01 ~]$ sudo su - We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things:     #1) Respect the privacy of others.     #2) Think before you type.     #3) With great power comes great responsibility. [sudo] password for natasha: [root@ststor01 ~]#

2.  Edit limit.conf file as below vi /etc/security/limits.conf

         (refer to you task for limits & add in the conf file)

[root@ststor01 ~]# vi /etc/security/limits.conf [root@ststor01 ~]# [root@ststor01 ~]# cat /etc/security/limits.conf | grep nproc | grep -v ^# nfsuser         soft    nproc   80 nfsuser         hard    nproc   92 [root@ststor01 ~]#

3. Click on Finish & Confirm to complete the task successful
