This article mainly introduces "how to add, enable and disable a warehouse in CentOS". In daily operation, I believe many people have doubts about how to add, enable and disable a warehouse in CentOS. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "how to add, enable and disable a warehouse in CentOS". Next, please follow the editor to study!

On RPM-based systems such as RHEL, CentOS, etc., many of us use the yum package manager to manage software installation, removal, update, search, and so on.

Most of the software in the Linux distribution comes from the official repository of the distribution. The official warehouse contains a large number of free and open source applications and software. It is easy to install and use.

Due to some limitations and proprietary issues, RPM-based distributions do not provide some packages in their official repository. In addition, for the sake of stability, it will not provide the core package of the * version.

In order to overcome this situation, we need to install or enable the required third-party warehouse. For RPM-based systems, there are many third-party repositories available, but few repositories are recommended because they do not replace a large number of base packages.

This can be done on RPM-based systems such as RHEL, CentOS, OEL, Fedora, etc.

Fedora systems use dnf config-manager [options] [section...]

Other RPM-based systems use yum-config-manager [options] [section...]

How to list enabled warehouses

Simply run the following command to check the list of warehouses enabled on the system.

For CentOS/RHEL/OLE systems:

# yum repolistLoaded plugins: fastestmirror SecurityLoading mirror speeds from cached hostfilerepo id repo name statusbase CentOS-6-Base 6706extras CentOS-6-Extras 53updates CentOS-6-Updates 1255repolist: 8014

For Fedora systems:

# how to add a new warehouse to the system by dnf repolist

Each warehouse usually provides its own .repo file. To add such a warehouse to the system, run the following command using the root user. EPEL repositories and IUS community repositories will be added in our example, see below.

But no .repo file is available for these repositories. Therefore, we use the following methods for installation.

For the EPEL repository, because it is available from the CentOS additional repository, run the following command to install it.

# yum install epel-release-y

For the IUS community repository, run the following bash script to install.

# curl 'https://setup.ius.io/'-o setup-ius.sh# sh setup-ius.sh

If you have a .repo file, in RHEL/CentOS/OEL, simply run the following command to add a repository.

# yum-config-manager-- add-repo http://www.example.com/example.repo Loaded plugins: product-id, refresh-packagekit, subscription-manageradding repo from: http://www.example.com/example.repograbbing file http://www.example.com/example.repo to / etc/yum.repos.d/example.repoexample.repo | 413B 00:00repo saved to / etc/yum.repos.d/example.repo

For Fedora systems, run the following command to add a warehouse:

# dnf config-manager-- add-repo http://www.example.com/example.repoadding repo from: http://www.example.com/example.repo

If you run the yum repolist command after adding these repositories, you can see the newly added repositories. Yes, I see it.

Note: whenever you run the yum repolist command, the command automatically gets updates from the appropriate repository and saves the cache on the local system.

Each warehouse has multiple channels, such as Testing, Dev, Archive, and so on. You can better understand this by navigating to the warehouse file location.

When you add a new repository by default, it will enable their stable repository, which is why we get the warehouse information when we run the yum repolist command. In some cases, if you want to enable their testing, development, or archiving repositories, use the following command. In addition, we can use this command to enable any disabled warehouse.

To verify this, we will enable epel-testing.repo by running the following command:

# yum-config-manager-- enable epel-testing Loaded plugins: fastestmirror==== repo: epel-testing = [epel-testing] bandwidth = 0base_persistdir = / var/lib/yum/repos/x86_64/6baseurl = cache = 0cachedir = / var/cache/yum/x86_64/6/epel-testingcost = 1000enabled = 1enablegroups = Trueexclude = failovermethod = priorityftp_disable_epsv = Falsegpgcadir = / var/lib/yum/repos/x86_64/6/epel-testing/gpgcadirgpgcakey = gpgcheck = Truegpgdir = / var/lib/yum/repos/x86_64/ 6/epel-testing/gpgdirgpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6hdrdir = / var/cache/yum/x86_64/6/epel-testing/headershttp_caching = allincludepkgs = keepalive = Truemdpolicy = group:primarymediaid = metadata_expire = 21600metalink = mirrorlist = https://mirrors.fedoraproject.org/metalink?repo=testing-epel6&arch=x86_64mirrorlist_expire = 86400name = Extra Packages for Enterprise Linux 6-Testing-x86_64old_base_cache_dir = password = persistdir = / var/lib/yum/repos / x86_64/6/epel-testingpkgdir = / var/cache/yum/x86_64/6/epel-testing/packagesproxy = Falseproxy_dict = proxy_password = proxy_username = repo_gpgcheck = Falseretries = 10skip_if_unavailable = Falsessl_check_cert_permissions = Truesslcacert = sslclientcert = sslclientkey = sslverify = Truethrottle = 0timeout = 30.0username =

Run the yum repolist command to check if "epel-testing" is enabled. It's enabled, and I can see it from the list.

If you want to enable multiple warehouses at the same time, use the following format. This command enables epel, epel-testing, and ius repositories:

# yum-config-manager-enable epel epel-testing ius

For Fedora systems, run the following command to enable the warehouse:

# dnf config-manager-how set-enabled epel-testing disables a warehouse in the system

Whenever you add a new repository by default, it enables their stable repository, which is why we get the warehouse information when we run the yum repolist command. If you do not want to use the warehouse, you can disable it with the following command.

To verify this, we will disable epel-testing.repo and ius.repo by running the following command:

# yum-config-manager-- disable epel-testing ius Loaded plugins: fastestmirror==== repo: epel-testing = [epel-testing] bandwidth = 0base_persistdir = / var/lib/yum/repos/x86_64/6baseurl = cache = 0cachedir = / var/cache/yum/x86_64/6/epel-testingcost = 1000enabled = 0enablegroups = Trueexclude = failovermethod = priorityftp_disable_epsv = Falsegpgcadir = / var/lib/yum/repos/x86_64/6/epel-testing/gpgcadirgpgcakey = gpgcheck = Truegpgdir = / var/lib/yum/repos/x86_64 / 6/epel-testing/gpgdirgpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6hdrdir = / var/cache/yum/x86_64/6/epel-testing/headershttp_caching = allincludepkgs = keepalive = Truemdpolicy = group:primarymediaid = metadata_expire = 21600metalink = mirrorlist = https://mirrors.fedoraproject.org/metalink?repo=testing-epel6&arch=x86_64mirrorlist_expire = 86400name = Extra Packages for Enterprise Linux 6-Testing-x86_64old_base_cache_dir = password = persistdir = / var/lib/yum/ Repos/x86_64/6/epel-testingpkgdir = / var/cache/yum/x86_64/6/epel-testing/packagesproxy = Falseproxy_dict = proxy_password = proxy_username = repo_gpgcheck = Falseretries = 10skip_if_unavailable = Truesslcacert = sslclientcert = sslclientkey = sslverify = Truethrottle = 0timeout = 30.0username = = repo: ius = [ius] bandwidth = 0base_persistdir = / var/lib/yum/repos/x86_64/6baseurl = cache = 0cachedir = / var/cache/yum/x86_64/6/iuscost = 1000enabled = 0enablegroups = Trueexclude = failovermethod = priorityftp_disable_epsv = Falsegpgcadir = / var/lib/yum/repos/x86_64/6/ius/gpgcadirgpgcakey = gpgcheck = Truegpgdir = / var/lib/yum/repos/x86_64/6/ius/gpgdirgpgkey = file:///etc/pki/rpm-gpg/IUS-COMMUNITY-GPG-KEYhdrdir = / var/cache/yum/x86_64/6/ius/headershttp_caching = allincludepkgs = keepalive = Truemdpolicy = group:primarymediaid = metadata_expire = 21600metalink = mirrorlist = https://mirrors.iuscommunity.org / mirrorlist?repo=ius-centos6&arch=x86_64&protocol=httpmirrorlist_expire = 86400name = IUS Community Packages for Enterprise Linux 6-x86_64old_base_cache_dir = password = persistdir = / var/lib/yum/repos/x86_64/6/iuspkgdir = / var/cache/yum/x86_64/6/ius/packagesproxy = Falseproxy_dict = proxy_password = proxy_username = repo_gpgcheck = Falseretries = 10skip_if_unavailable = Falsessl_check_cert_permissions = Truesslcacert = sslclientcert = sslclientkey = sslverify = Truethrottle = 0timeout = 30.0username =

Run the yum repolist command to check that the "epel-testing" and "ius" repositories are disabled. It's disabled. I can't see those warehouses, except for "epel".

For Fedora systems, run the following command to enable a warehouse:

# dnf config-manager-set-disabled epel-testing

Alternatively, you can do this by manually editing the appropriate repo file. To do this, open the appropriate repo file and change the value from enabled=0 to enabled=1 (enable warehouse) or from enabled=1 to enabled=0 (disable warehouse).

That is, from:
