The ifconfig and netstat commands cannot be found in Centos7.
Centos7 has been released for some time, and some problems have also been found recently. After Centos6 was changed, I felt a lot of subtle changes.
For example, ifconfig and netstat commands are not provided by default. ifconfig can be replaced by the ip addr command,
The ss Command in cenots6 can replace netstat, but the current ss is exactly the same as the previous one. You still have to install it to view port occupation and tcp link attacks.
Just wrap net-tools.
Yum install net-tools
In addition, centos7 introduces systemctl to manage services, which is indeed not as good as the original service. php defaults to 5.4, apache defaults to 2.4, and Mariadb replaces mysql
Now, from the installation to the internal software package, we can see that the rhl series system is like the Community edition fedora.
