Centos 7 impressions

Yesterday (2014/07/07) CentOS announced the release of CentOS 7 for 64 bit x86 compatible machines.

This is the first release for CentOS-7 and is version marked as 7.0-1406

Today I found some time to check what’s new in CentOS 7. 

I have downloaded:

Size: 4148166656


After downloading the iso file and checking the sha256sum I created a vm (my hypervisor is Hyper-v) and connected it to a vSwitch. After a very simple installation process (maybe the simplest I ever faced) completed, and when the vm booted, I tried to setup network configuration. I edited as usual, the /etc/sysconfig/newtork-scripts/ifcfg-eth0 file and tried to restart network service.

# service network restart
Restarting network (via systemctl):                        [  OK  ]

That was strange enough! What is the systemctl? I will give more details later!
After that I tried to check my ip:

# ifconfig -a
-bash: ifconfig: command not found

That was strange too, because there was the first time I found a unix like system without ifconfig tool installed by default.

I thought that the ip command will be there and executed:

# ip addr

which indeed was there! After connecting through a terminal, the first command I run is:

# yum upgrade


Then I installed the ifconfig command (net-tools):

# yum install net-tools


Ok now, I want to say that the best way to see the changes and the new features of CentOS 7, is to get a cold beer, some snacks and read all the redhat documentation:


and the redhat administrators guide for RHEL 7.0:


One last thing I want to mention is the distrowatch package version list:


where you can see that you can find php 5.4, apache 2.4 and Mariadb instead of MySQL.

  1. não consigo executar o comando yum install net-tools, apresenta erro, sera que estou fazendo algo errado.

    quando executo aparece uma sequencia de 4 alternativas e não executa

    1. I cannot fully understand your language but as far as my understanding you said that the when you execute the command yum install net-tools on a centos 7 system an error appears. Could you please paste the output of command execution on a commend in order to help you figure out the issue?
