Xcat Installation and update software

Next several Xcat articles, today to see how xcat Install and upgrade software, we sub-install the update release package and non-release package two cases.

First use the Lsdef command to see the osimage information, such as

Lsdef-t osimage centos6.6-x86_64-install-compute    ... pkgdir=/install/centos6.6/x86_64    pkglist=/opt/xcat/share/xcat/install/centos/compute.centos6.pkglist    otherpkgdir=/install/custom/centos6.6/x86_64/    Otherpkglist=/install/custom/centos6.6/x86_64/mypkgs.pkglist ...

Notice here a few of the properties listed above
* Pkgdir defines the location of the release package
* Pkglist defines the list of distribution packages to be installed
* Otherpkgdir defines the location of the non-release package
* Otherpkglist defines the list of non-release packages to be installed
If a property is missing, the description does not specify this property at the time of definition.

Install the update release package

1. To install or update a package in a release, simply add the package you want to install or update to the pkglist defined file
2. Run the "Updatenode <noderange>-S" command

Install the update non-release package

1. First create a directory to put additional packages, such as

  Mkdir-p/install/custom/centos6.6/x86_64/

2. Then copy the additional RPM package to this directory, for example, using the HELLOWORLD-1.0.0-1.EL6.X86_64.RPM package generated in my previous blog

  CP helloworld-1.0.0-1.el6.x86_64.rpm/install/custom/centos6.6/x86_64/

3. Run "Createrepo" in this directory to create a local warehouse

  cd/install/custom/centos6.6/x86_64/  Createrepo.

4. Create a Package installation list file, such as "/install/custom/centos6.6/x86_64/mypkgs.pkglist", which reads as follows:

HelloWorld

5. Modify the Otherpkgdir and Otherpkglist properties of the OSImage

Chdef-t osimage centos6.6-x86_64-install-compute     otherpkgdir=/install/custom/centos6.6/x86_64/     Otherpkglist=/install/custom/centos6.6/x86_64/mypkgs.pkglist

6. Run the "Updatenode <noderange>-S" command to install the new package

7. If you want to update the package, simply place the new RPM package in the/install/custom/centos6.6/x86_64/directory and run the "Updatenode <noderange>-S" command again.
