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

The code is as follows:

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

It will prompt:

The code is as follows:

...

Setting up Update Process

No Packages marked for Update

Skills (tip)

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

It means that the addition is successful!
