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
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)

_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
