how do I install ansible in centos 7

[Jcenos7]

Team,

Question: 1 - How to install ansible in Centos 7.

I am trying to install ansible in centos 7, but unable to, could you please help me with procedure.

Tried this already:
1. yum install epel-release
2. yum install ansible <---- but I am not getting any ansible package.
3. shall I download ansible package directly from site or it require any dependent packages as well ?

So please suggest

Question: 2
Any idea when CentOS 9 will be released or CentOS won't release any new ?


Regards
Jay

Apparently you did not install epel-release or the repo is not enabled. EPEL has ansible.

Code: Select all

[root@centos7 ~]# yum list ansible\*
Loaded plugins: priorities
173 packages excluded due to repository priority protections
Available Packages
ansible.noarch                              2.9.27-1.el7                  epel  
ansible-collection-microsoft-sql.noarch     1.1.0-1.el7_9                 extras
ansible-doc.noarch                          2.9.27-1.el7                  epel  
ansible-inventory-grapher.noarch            2.4.4-1.el7                   epel  
ansible-lint.noarch                         3.5.1-1.el7                   epel

ansible-review.noarch                       0.13.4-1.el7                  epel

Never. Red Hat cancelled CentOS about a year after CentOS 8 was released (it's now dead).

Thank you for your response!, I will check and get back.

Make sure you have installed the correct epel-release package for CentOS 7. It should be epel-release-7-14.noarch so if yours is epel-release-8 or -9 then it's for a different version of RHEL, not for 7.

We ship the correct package in the CentOS 7 'extras' repo so you should be able to just yum remove the current one and then yum --enablerepo=extras install epel-release

An alternative to EPEL is CentOS SIG's repo:

Code: Select all

yum install centos-release-ansible-29
yum install ansible

The package 'centos-release-ansible-29' should be in the 'extras' repo.

Note though that EPEL and SIG pack ansible bit differently, and are thus
mutually exclusive on that aspect.

Sorry to ask again, no more centos release will come ? and what about centos stream 8 and 9 ?

Soon after the Red Hat's announcement about CentOS two new projects did start. They are AlmaLinux and Rocky Linux.
Their mission is: Do what CentOS did (but better).

CentOS 7 is a clone of RHEL 7. Similarly,
AlmaLinux 8 and Rocky Linux 8 are clones of RHEL 8 and
AlmaLinux 9 and Rocky Linux 9 are clones of RHEL 9.

Clones are downstream from RHEL; RHEL releases something and the clones rebuild it for their distros.


RHEL codebase has "main / development" branch. That is where Red Hat adds and tests content for future releases.

At some point, branches "9.0", "9.1", and "9.2" have been created off the RHEL 9 main branch.
Content in those branches was polished and then released as RHEL 9.0, RHEL 9.1, and RHEL 9.2, respectively.
For some time Red Hat backports (security) fixes into these "production" branches.

CentOS Stream 9 has content from the main branch. It is a view to upstream. What visits the Stream
may or may not show up in RHEL. It is alpha/early beta content. Point is, we can see (some of) where RHEL is going.

The need for RHEL 9 main branch (and hence Stream 9) ends when the last "9.x" branch is created. In 2027.
The "9.x" branch (and hence the clones) will be maintained to 2032.
