The Yum package manager has been replaced by DNF.
Usage
| Task | Command |
|---|---|
| Clean and update repository metadata | # yum clean all
# yum update
|
| Install a package by name | # yum install <package>
|
| Remove a package by name | # yum remove <package>
|
| Upgrade a package | # yum update <package>
|
| Search for a package | # yum search <package>
|
| Search for a package by provided file | ## To find any package that provides *bin/netcat as a file
# yum whatprovides \*bin/netcat
|
| List installed packages | # rpm -qa
|
| Determine which package provided a file | # rpm -qf <path to file>
|
Yum repositories are placed in /etc/yum.repos.d. Typically, yum logs will show all actions taken by yum at /var/log/yum.rpm.log.
Excluding Packages
To exclude a package from being installed, use the -x option or add to the exclude attribute in the /etc/yum.conf file.
The list is separated by a space and supports wildcards. For example:
exclude=cpsc-uml pack* package3
DNF Specific
If you are usingdnf such as on CentOS 8, or a recent version of Fedora, you need to add the exclude line in the /etc/dnf/dnf.conf file under the [main] section.
For example:
[main]
gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
deltarpm=0
exclude=lightdm-webkit2-greeter
Troubleshooting
thread.error: can't start new thread
While attempting to install a package on a VPS, I encountered:
[root@drache ~]# yum install php-mysql
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Traceback (most recent call last):
File "/usr/bin/yum", line 29, in ?
yummain.user_main(sys.argv[1:], exit_code=True)
File "/usr/share/yum-cli/yummain.py", line 309, in user_main
errcode = main(args)
File "/usr/share/yum-cli/yummain.py", line 178, in main

self.repos.populateSack(which=repos)
File "/usr/lib/python2.4/site-packages/yum/repos.py", line 232, in populateSack
self.doSetup()
File "/usr/lib/python2.4/site-packages/yum/repos.py", line 79, in doSetup
self.ayum.plugins.run('postreposetup')
File "/usr/lib/python2.4/site-packages/yum/plugins.py", line 179, in run
func(conduitcls(self, self.base, conf, **kwargs))
File "/usr/lib/yum-plugins/fastestmirror.py", line 181, in postreposetup_hook
all_urls = FastestMirror(all_urls).get_mirrorlist()
File "/usr/lib/yum-plugins/fastestmirror.py", line 333, in get_mirrorlist
self._poll_mirrors()
File "/usr/lib/yum-plugins/fastestmirror.py", line 376, in _poll_mirrors
pollThread.start()
File "/usr/lib64/python2.4/threading.py", line 416, in start
_start_new_thread(self.__bootstrap, ())
thread.error: can't start new thread
The solution was to disable the fastest mirror plugin by editing /etc/yum/pluginconf.d/fastestmirror.conf and setting enable=0
[main]
enabled=0
verbose=0
socket_timeout=3
hostfilepath=/var/cache/yum/timedhosts.txt
maxhostfileage=10
maxthreads=15
#exclude=.gov, facebook
Bad id for repo: My Repo, byte = N
After adding a custom repository, running yum or dnf resulted in this error:
Bad id for repo: Local EPEL - Everything, byte = 5
Bad id for repo: Local EPEL - Modular, byte = 5
The issue here is the space. Replace the spaces with dashes or underscores and try again.
