Shell script to find the disk details of Remote server in Linux

Sample shell script to find the disk details of remote server in linux. Here i denotes the server from 1 to 13 and shark1 is the file where the output are stored.

In Shell script you may need to disable host key checking using StrictHostKeyChecking

For more details on sshpass Click here

for i in `seq 1 1 13`; do sshpass -ftest.txt  ssh -o  StrictHostKeyChecking=no  tester@xxx$i.example.com "hostname && df -Th " >> shark1; done

[root@test ~]# cat shark1

SSHPASS command to find the details of Remote Server in linux

How to use ssh in SHELL SCRIPT. You can use sshpass command to use ssh in shell script. Below is the syntax to find the mounted partition details of the remote server from local machine.

sshpass -p 'Mute4@sec' ssh saikrishna.b@xxserver.com df

[root@test ~]# cat test.txt

Mute4@sec

With out showing the password you can store the password in a file and call them . Here -f denotes file and test.txt is the file where the password has been stored.

Rebuild rpm database

Rebuilding corrupted RPM database

Method # 1

Remove /var/lib/rpm/__db* files to avoid stale locks:
# cd /var/lib
# rm __db*

Rebuild RPM database:
# rpm --rebuilddb
# rpmdb_verify Packages

Method # 2

If you are facing the issue still, try with the below commands

cd /var/lib/rpm
# mv Packages Packages_backup2013
# db_dump Packages_backup2013 | db_load Packages
# rpm -qa
# rpm --rebuilddb

Install and Configure NFS server

Three rpm are required to configure nfs server. nfs, portmap, xinetd check them if not found then install

[root@test ~]# rpm -qa nfs*
nfs-utils-lib-1.1.5-4.el6.x86_64
nfs-utils-1.2.3-26.el6.x86_64
nfs4-acl-tools-0.3.3-6.el6.x86_64
[root@test ~]# rpm -qa xinetd*
[root@test ~]# rpm -qa xinetd
[root@test ~]# rpm -qa portmap
[root@test ~]# yum install portmap
