It's a bash script to show a complete inventory of an Linux OS and it might be useful for Linux system/support engineers who lot of servers in daily life . Instead of manually executing all the commands on each of server which is hell lot of task to do , you can execute this script and this script generates all needed inventory to a file which you can mail to your manager.
This is a small project done by me after studying shell scripting and i have used mix of different concepts like functions , conditional statements , loops , exit status , command chaining , and used different text processing commands like awk ,sed , grep , cut etc ...
The script will collect informations from OS such as :
- OS Details ( such as Hostname , OS_name , OS_version , OS_Kernel_Version )
- Hypervisor Details
- CPU Details ( such as No of cores , CPU type , CPU usage , Load Average of server)
- Memory Details
- Disk Detais
- Network Detail ( like IP address , DNS SERVERS , DNS_DOMAIN , Total no of interfaces , List of interfaces )
- SELINUX status
- SWAP details
- netstat package must be available
- Passwordless SSH authentication b/w servers ( Note If you are using password environment u have to use sshpass utility to provide password )
- Common user accross all servers
- Sudo privilege to that user
This script currently supports only rhel 7.x and 8.x (ubuntu servers will be added in future release)
- Create a user common in all servers and make passwordless authentication connection b/w the servers. (Give sudo access to the user)
- Switch to that user.
- git clone https://github.com/NITHIN-JOHN-GEORGE/MULTIPLE-SERVER-INVENTORY-SHELL-SCRIPT.git
- cd MULTIPLE-SERVER-INVENTORY-SHELL-SCRIPT
- chmod +x MULTIPLE_SERVER_INVENTORY.sh
- Create a servers_list.txt with updated list of server in which you need inventory.
- Update the username in the script starting
USER=<username>
- ./MULTIPLE_SERVER_INVENTORY.sh
