I am trying to install nagios 4.0.6 and nagios -plugins-2.0.2 on fedora 17.
I have followed steps which is mentioned in sourceforge documentation.
http://nagios.sourceforge.net/docs/3_0/quickstart-fedora.html
unfortunately /usr/local/nagios/bin/nagios this file isnt created I mean even bin folder haven't created. so that I am unable to start nagios service.
What should I do?
You can install Nagios right from the Fedora repositories.
yum install nagios nagios-plugins
You can also see a list of Nagios-related packages with: yum search nagios.
I suggest you always install apps from the repositories, since the package manager will take care of the dependencies as well as the installation, and the packages there have been already revised and tested for the version of your OS. Use only 3rd party source builds or install/build the packages manually as a last resort.

I am new to Linux,
I installed openSUSE Leap 15.4, and made the root directory ext4, I then followed these steps to install postgreSQL 13 on my system
1.sudo zypper ref && sudo zypper update
sudo zypper addrepo https://download.postgresql.org/pub/repos/zypp/repo/pgdg-sles-15-pg13.repo
But after this, I sudo zypper ref again and it shows an error saying:
Retrieving repository 'PostgreSQL 13 SLES 15.4 - x86_64' metadata .....................................[error]
Repository 'PostgreSQL 13 SLES 15.4 - x86_64' is invalid.
[pgdg-13|https://download.postgresql.org/pub/repos/zypp/13/suse/sles-15.4-x86_64] Valid metadata not found at specified URL
History:
- [pgdg-13|https://download.postgresql.org/pub/repos/zypp/13/suse/sles-15.4-x86_64] Repository type can't be determined.
what can I do to install postgreSQL
I can't say precisely why your zypper command failed, but it might have to do with the fact that the repositories from your link are intended for SUSE Linux Enterprise 15 SP4, not for openSUSE Leap 15.4, which is what you're using. So even if you did get these repositories to work, you might run into other compatibility problems later.
To install postgresql, there is always the option to search for your package on software.opensuse.org. (I strongly recommend you bookmark this page – it's the place to look for openSUSE packages.) For postgresql13, there is indeed an official experimental package available for openSUSE 15.4, namely here, which you can install via 1-Click-Install. However, the newer version postgresql14 is already out for quite a while, so I would only advise for using the older postgresql13 if you have a very strong reason to do so. The newer postgresql14 also has an official experimental package available for openSUSE 15.4, namely here; this is the one I would recommend currently.
first check if repo is enabled zypper repos -d
check /etc/zypp/repos.d/pgdg-13.repo file
If you open the added repo file all set sles. but i think the main problem is the type=rpm-md. In any case you dont need add third part repo to install postgress. the package is already in the main repos and is called postgresql-server.
So remove the https://download.postgresql.org/pub/repos/zypp/repo/pgdg-sles-15-pg13.repo to prevent any other issues and package conflicts
zypper lr # to list the repos and find the number for the `https://download.postgresql.org/pub/repos/zypp/repo/pgdg-sles-15-pg13.repo`
zypper rr <number>
Then just install postgresql-server
Btw when you refresh the packages you dont need to run update

Closed 2 years ago.
we have rhel linux machine without network access
and we want to install ansible on that machine
but we want to install the ansible from binaries ( not like pip/yum install ) , because we want to avoid any pip dependencies issues
is any approach that is relevant ?
example of the legacy way
Step 1: Update your Control Node
Any time you are installing new software, it is a good idea to ensure your existing operating system software is up to date. Let’s start with that task first.
yum update
Step 2: Install the EPEL Repository
Installing Ansible is pretty straightforward. First, we’ll need to install the CentOS 7 EPEL repository.
yum install epel-release
Step 3: Install Ansible
Next, we install the Ansible package from the EPEL repository.
yum install ansible
Perhaps not ideal, but you can just run from source. I've done it that way for years without any problems. I just put the initialization routine in my .bashrc file, so it's always ready to use.
Running Ansible from source (devel)
Once you pull from git on a machine that has internet access, sneakernet it over to the machine you want it on.
As mentioned in the official documentation you can use rpm available in official release repo. Since you dont have internet access you will have to download it somewhere else & copy it over to control node.
RPMs for currently supported versions of RHEL, CentOS, and Fedora are available from EPEL as well as releases.ansible.com.
Or
You can also build an RPM yourself. From the root of a checkout or tarball, use the make rpm command to build an RPM you can distribute and install
However I would not recommend Running Ansible from source (devel) because as already mentioned in the doc, this could be unstable.
Note
You should only run Ansible from devel if you are actively developing content for Ansible. This is a rapidly changing source of code and can become unstable at any point.
If you would like to build rpm on your own, you should probably use the tagged releases.
Available both in github & Ansible releases
What is a repository in Centos and what does it contain. I I remove all the .repo files from the system. What will be its implications. Will it remove the packages as well and will hinder normal operations or will package just not get auto-updated?
"Repositories" are locations where you can download software.
".repo" files are definition files for repositories you might wish to use.
Deleting a .repo file will not affect any packages you already have installed - it will just prevent you from updating it (assuming the package in question is available only from that one repository).
You can learn more here:
https://www.centos.org/docs/5/html/yum/sn-yum-maintenance.html
https://www.digitalocean.com/community/tutorials/how-to-set-up-and-use-yum-repositories-on-a-centos-6-vps
Repositories in CentOS are collections of software that the server administrator can easily install.
For instance, should you choose to install Firefox, the following command will query all configured repositories, and if one of the repos has Firefox then yum will download and install it:
$ sudo yum install firefox
Additionally, you can search for software without installing it:
$ yum provides firefox
Therefore, repositories (or repos) are online collections of software which yum may query and download from.
I am trying to install bigtop on centos6 (VM using virtualbox).
I am following links given below with little modifications to get latest versions (bigtop 1.1.0) -
http://www.dummies.com/how-to/content/set-up-the-hadoop-environment-with-apache-bigtop.html
https://cwiki.apache.org/confluence/display/BIGTOP/How+to+install+Hadoop+distribution+from+Bigtop+0.5.0
To be precise, I have run following commands till now -
wget -O /etc/yum.repos.d/bigtop.repo http://www.apache.org/dist/bigtop/bigtop-1.1.0/repos/centos6/bigtop.repo
yum install hadoop\* mahout\* oozie\* hbase\* hive\* hue\* pig\* zookeeper\*
Now the problem is, it says -
No package hadoop* available.
No package hue* available.
No package zookeeper* available.
I am new to linux and don't completely understand what exactly these commands are doing. I have wasted an entire day on this. As I am just trying to explore hadoop on my VM, I am fine if I can get some older version of bigtop too but I would prefer that I can get atleast hadoop 2.0 or above.
Can someone help on this?
Thanks.
You have to run sudo apt-get update between adding new repository and installing packages from it.
To install additional packages for Cygwin, do I just need to run the setup.exe again and choose from the packages list?
Also, doing this won't harm my computer in terms of 2 Cygwin instances being installed or problems of that kind (I'm kind of a noobie with these things).
Last, there is no package manager in Cygwin which you can run in the command line? Something similar to Pip in Python.
No, adding additional packages doesn’t modify the current settings. There is a
package manager called apt-cyg which installes additional packages from
command-line. To install apt-cyg follow the below steps:
wget rawgit.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin
Note: wget should be installed for downloading the apt-cyg. To Use apt-cyg for
installing additional package (after following the above steps):
apt-cyg install ncurses
No, it doesn't hurt the current setup. The install program knows what's installed already.
Having said that, I long ago got into the habit of installing all of Cygwin since, despite its size, it's still minuscule compared to the size of modern hard disks. That way, you won't ever have to worry about whether a package is installed or not.
Re-run the setup executable like "cygwin_setup-x86_64.exe" should do it.
"Install from Internet"
Accept your existing root directory (from your existing installation)
Use your existing "Local Package Directory"
On the screen, view "Full"
Search for the new package you want to add
Go through the installation
Additional option, may be helpful for someone:
To install additional packages in windows from windows command line you can use your cygwin installer.
I suppose, you've already downloaded it to install cygwin from here https://cygwin.com/install.html.
$ setup-x86_64.exe -q -P graphviz
see this guide for details:
http://preshing.com/20141108/how-to-install-the-latest-gcc-on-windows/
There is no package management in Cygwin outside of the setup program. The setup only applies updates to your current installation, it does not overwrite packages than what you already have.
So if you want new packages just rerun the setup program to install packages.
You can just look for the package binaries and decompress them in the C:\cygwin\bin folder.
I did that for dos2unix ( https://cygwin.com/packages/summary/dos2unix.html ) and trying it out now.
