The process of learning Linux to enter a job must go through an interview. Same as other technical positions. Linux operation and maintenance also requires manager human interview and technical interview. The interview questions for junior operation and maintenance engineers are relatively simple, but there are also many friends who make mistakes on simple questions. Here are some common Linux operation and maintenance interviews.
Common Linux operation and maintenance interview questions to share
1. How to add a new 50G hard disk to the Linux server system as a separate partition and is it in use? What steps are required?
a. Put the hard disk in the server and connect it
b. Create hard disk partition (fdisk command)

3. There is a mobile hard disk with 300G data on it, how to quickly cp to the Linux server?
Suppose the hard disk is recognized as sdbc on the server

mount-tntfs/dev/sdbc/mydata
4. There is a httpd-2.2.15.xx.rpm package in the CD. How to mount and install it?
a. Mount the CD to /mnt (mount/dev/cdrom/mnt)
b. Installation (rpm-ivh/mnt/Packages/httpd-2.2.15.xx.rpm)

Install rpm-ivhntp-0.7.12.x86_64.rpm
Uninstall rpm-entp--nodeps
Update rpm-Uvhntp-0.7.12.x86_64.rpm
6. /var/www/html/ is the publishing directory of the website. How to automatically back it up at 0:30 in the morning every day and write out the operation steps?
a, crontab-e enters the edit mode
b. Add the following content 300***/bin/tar-czf/backup/web_bak_$(date+%Y%m%d).tar.gz/var/www/html>/dev/null2>&1
c, start the service servicecrontabstart; chkconfigcrontabon
7. Use the tar command to pack and compress the /root directory, then move it to /tmp, and set its permissions to be read-only by others.
tar-czf / tmp / root_bak.tar.gz / root
chmodo = r / tmp / root_bak.tar.gz
