Locking the specified software version in a Yum upgrade prevents it from upgrading as follows:
1. To install versionlock first, type:
The code is as follows:
# yum install yum-versionlock
two。 View / etc/yum/pluginconf.d/versionlock.conf file
The code is as follows:
# vi / etc/yum/pluginconf.d/versionlock.conf
It is displayed as:
The code is as follows:
[main]
Enabled = 1
Locklist = / etc/yum/pluginconf.d/versionlock.list
# Uncomment this to lock out "upgrade via. Obsoletes" etc. (slower)
# follow_obsoletes = 1
Enabled = 0 | 1
Turn versionlock on or off
The code is as follows:
Locklist = / path/to/file
Define the absolute path to the versionlock lock software list file versionlock.list, here / etc/yum/pluginconf.d/versionlock.list
/ etc/yum/pluginconf.d/versionlock.list, the format of the locked file is one package name per line
Make sure you have enabled = 1 in the file, and add it if you don't. After installation, the default enabled is 1, that is, the versionlock plug-in is enabled.
3. Add the name and version of the package that needs to be locked to / etc/yum/pluginconf.d/versionlock.list, one line per line
Suppose we want to lock the version of nagios-plugins and not let yum upgrade it, then copy the following line into versionlock.list

Nagios-plugins-1.4.11-1.el5.rf.x86_64
Save versionlock.list after you add it, and try the following command to try to upgrade nagios. Input
The code is as follows:
# yum update nagios-plugins

In fact, a better way is to use the pipe command to directly add the name of the package to be locked to versionlock.list. If you lock the ppp upgrade here, type:
The code is as follows:
# rpm-qa | grep ppp > > / etc/yum/pluginconf.d/versionlock.list
Then, check whether the addition is successful or not, and enter:
The code is as follows:
# cat / etc/yum/pluginconf.d/versionlock.list
If the display:
The code is as follows:
Ppp-2.4.4-2.el5
