[SOLVED] CentOS 7 for 32 bit Machines.

gardenair · 11-09-2015, 05:07 AM

hi,
I have just download CentOS 7 (32 bit) for my old server from the site

http://seven.centos.org/2015/10/cent...#comment-79066

The mirror site is

http://mirror.centos.org/altarch/7/isos/i386/

I want to know that does this architecture is alternate for 32 bit machines ? Can I use it in production environment as well ?

Thanks,
gardenair

From the announcement:

Quote:

This version of CentOS Linux 7 is for PAE capable 32 bit machines, including x86 based IOT boards similar to the Intel Edison.

Since the goal of Centos is to provide an Enterprise Linux without licensing, the answer should be yes. For what other reason would they create this alternative? Best to confirm this with the AltArch SIG though.

Well I have just install the said version over VMWare workstation for testing purpose. It has been installed. I found Centos 7 different from Centos 6,For example to turn off firewall the new command is here .

Code:

[root@localhost ~]# systemctl disable firewalld
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm '/etc/systemd/system/basic.target.wants/firewalld.service'

I have to upgrade my skill regarding to learn the new command which I found in centos 7.

That's why it's a major new revision. systemd may be the biggest change, together with the network management tools, and certainly the most controversial. Luckily RedHat has excellent documentation at access.redhat.com.

thanks for the reply. Well as concern to services In CentOS 7 I even can not the traditional command to run the service like in CentOS 5 and CentOS 6

Code:

# service smb start

Under VMWare workstation I even can not connect the network of guest operating system (centos 7) with the base operating system,where as under CentOS6 it works fine and i can ping each other as well.

CentOS7... is

Yes, a lot has changed in RHEL/CentOS 7. The new command is systemctl, eg: "systemctl start smb". It's a little more intuitive now, eg:

CentOS 6

Code:

chkconfig smb on
service smb start

CentOS 7

Code:

systemctl enable smb
systemctl start smb

so i take it you did not read the required reading called " the release notes "

this is not new in 7.1
rhel started using systemd in 7.0

the first beta for 7 was released 2 YEARS ago
the use of systemd is not new news

Thanks for the reply.Well i have installed Server with GUI as I choose "File and Storage server". After installation i use the command

Code:

# rpm -qa | grep samba

It show the samba related files but samba-winbind is missing with the fresh installation.
In CentOS 6 during fresh installation i add these storage components.

You can see the output of the said command by using CentOS 6 and CentOS 7.
The question is how may I add "samba-winbind" under CentOS 7.

Thanks

Packages on Centos 7 may not be the same as on Centos 6. Perhaps there is no samba-winbind.

yum search samba should give you ideas.

Well what is the main reason that Red Hat introduce "systemctl" why it not continue the previous things,I agree that in the version 7 there is lot of improvement but the "service "," chkconfig" concept on RHEL 6 is now not in the latest version.
In short again start to read the documentation,learn,practice and then move ahead on to production environment ...

Create a new thread for new questions.

In most cases I would agree. However, since most systemd threads tend to get out of control, gardenair please do not.

In a nutshell, chkconfig and the service commands are used to control the init system on RedHat 6/CentOS 6. The old init system was replaced by systemd which now uses the systemctl command.

Here is a very detailed explanation why Arch Linux moved to systemd. Certainly Red Hat, SUSE, Debian etc had similar considerations.
