Install
cd /etc/yum.repos.d/ on CentOS Linux release 7.6.1810 (Core) and
move the original repo file to another place for backup.
mv /etc/yum.repos.d/CentOS-Base.repo{,.bak}
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos -7.repo
wget https://packages.ntop.org/centos-stable/ntop.repo -Ontop.repo
yum install epel-release
yum update (note that this software is to upgrade the software and system, please operate with caution)
If you encounter kernel conflicts or file conflicts during the upgrade process, you can use the following commands according to the situation:
yum update --exclude=kernel* --exclude=centos-release* --exclude=initscripts*
If the relevant debugging of the installation package cannot be found during the installation process, you need to check whether the repo.repo file is related again. If the installation still fails, check the relevant content of this file.
If there is a package conflict during the installation process, for example, the following error occurs:
Error: Package: 1:mariadb-5.5.68-1.el7.x86_64 (base)
Requires: mariadb-libs(x86-64) = 1:5.5.68-1.el7
Installed: 3:mariadb-libs-10.1.17-1.el7.x86_64 (@repo)
mariadb-libs(x86-64) = 3:10.1.17-1.el7
Available: 1:mariadb-libs-5.5.68-1.el7.x86_64 (base)
mariadb-libs(x86-64) = 1:5.5.68-1.el7
You could try using --skip-broken to work around the problem
You can use the following methods to solve:
[root@computer1 ~]# rpm -qa|grep -i mariadb
mariadb-config-10.1.17-1.el7.x86_64
mariadb-libs-10.1.17-1.el7.x86_64
mariadb-common-10.1.17-1.el7.x86_64
Then use yum remove mariadb-libs-10.1.17-1.el7.x86_64
Just uninstall the relevant package.
After the upgrade, the operating system becomes CentOS Linux release 7.9.2009 (Core)

Note: When the Huawei switch is doing port mirroring, the traffic entering and exiting the network card can only see the incoming traffic on the monitoring port, but not the outgoing traffic. Therefore, the traffic entering the monitoring port is the sum of the traffic on the inboud and outboud ports.
