yum package method body is not modified. Comes from cfengine_std.cf
library for 3.3.5 version of cfengine. The only thing I've changed
yesterday is package_list_update_ifelapsed => "0" but it's only for
testing purpose and I'm going to leave it 240 in production and define
new package_method.
By the way seems like yum_rpm method works a bit faster that yum.
body package_method yum
{
package_changes => "bulk";
package_list_command => "/usr/bin/yum list installed";
package_patch_list_command => "/usr/bin/yum check-update";
# Remember to escape special characters like |
package_list_name_regex => "([^.]+).*";
package_list_version_regex => "[^\s]\s+([^\s]+).*";
package_list_arch_regex => "[^.]+\.([^\s]+).*";
package_installed_regex => ".*(installed|\s+@).*";
package_name_convention => "$(name).$(arch)";
# set it to "0" to avoid caching of list during upgrade
#package_list_update_ifelapsed => "240";
package_list_update_ifelapsed => "0";
package_patch_installed_regex => "^[^*]\s.*";
package_patch_name_regex => "([^.]+).*";
package_patch_version_regex => "[^\s]\s+([^\s]+).*";
package_patch_arch_regex => "[^.]+\.([^\s]+).*";
package_add_command => "/usr/bin/yum -y install";
package_update_command => "/usr/bin/yum -y update";
package_delete_command => "/bin/rpm -e --nodeps";
package_verify_command => "/bin/rpm -V";
}
##
body package_method yum_rpm
# Contributed by Trond Hasle Amundsen
# More efficient package method for RedHat - uses rpm to list instead of yum
# Notes:
# - using $(name).$(arch) instead of $(name) for package_name_convention
# causes uninstallation to fail.
# - using allmatches to remove for all architectures
#
{
package_changes => "bulk";
package_list_command => "/bin/rpm -qa --qf '%{name} %{version}-%{release}
%{arch}\n'";
package_patch_list_command => "/usr/bin/yum check-update";
package_list_name_regex => "^(\S+?)\s\S+?\s\S+$";
package_list_version_regex => "^\S+?\s(\S+?)\s\S+$";
package_list_arch_regex => "^\S+?\s\S+?\s(\S+)$";
package_installed_regex => ".*";
package_name_convention => "$(name)";
# set it to "0" to avoid caching of list during upgrade
package_list_update_ifelapsed => "240";
package_patch_installed_regex => "^[^*]\s.*";
package_patch_name_regex => "([^.]+).*";
package_patch_version_regex => "[^\s]\s+([^\s]+).*";
package_patch_arch_regex => "[^.]+\.([^\s]+).*";
package_add_command => "/usr/bin/yum -y install";
package_update_command => "/usr/bin/yum -y update";
package_delete_command => "/bin/rpm -e --nodeps --allmatches";
package_verify_command => "/bin/rpm -V";
}
Test bundle code (same as previous, except for commands promise):
bundle agent packages {
vars:
!vz_hardware_node.!vz_container::
"kernel_package" slist => {
"mc",
},
comment => "Define kernel to install arch specifi",
handle => "packages_vars_kernel_package";
packages:
!vz_hardware_node.!vz_container::
"$(packages.kernel_package)"
package_policy => "add",
package_architectures => { "x86_64" },
package_method => yum_rpm,
classes => if_repaired("restart_machine");
}
1. This output is for yum_rpm method with mc paackage not installed.
