Unable to ping the external network under centos7
Problem:
After the installation of the CentOS system was completed, I found that the system did not automatically assign an IP, and the external network was not accessible.
Cause:
This is because the network card is not activated. Just edit the ifcfg_ens33 file to activate it.
Solution:
1. Enter the network card configuration directory
cd /etc/sysconfig/network-scripts/
2. Open the network card configuration file
vi ifcfg-ens33
3. Change ONBOOT=no to ONBOOT=yes, save and exit.
4. Restart the network service
service network restart

How to access and clean junk files in /tmp directory in CentOS 7?
Dec 27, 2023 pm 09:10 PM
There is a lot of garbage in the tmp directory in the centos7 system. If you want to clear the garbage, how should you do it? Let’s take a look at the detailed tutorial below. To view the list of files in the tmp file directory, execute the command cdtmp/ to switch to the current file directory of tmp, and execute the ll command to view the list of files in the current directory. As shown below. Use the rm command to delete files. It should be noted that the rm command deletes files from the system forever. Therefore, it is recommended that when using the rm command, it is best to give a prompt before deleting the file. Use the command rm-i file name, wait for the user to confirm deletion (y) or skip deletion (n), and the system will perform corresponding operations. As shown below.
