我今天遇到了类似的要求,但是如果事情可以通过其他任何方式解决,我都不喜欢执行人员。因此,我选择了另一条路径,并为“ yumgroup”编写了一个简单的自定义类型。只需将这些文件放在模块路径中的任何模块中即可:
“模块名称/ lib /人偶/提供者/yumgroup/default.rb”
Puppet::Type.type(:yumgroup).provide(:default) do
desc 'Support for managing the yum groups'
commands :yum => '/usr/bin/yum'
# TODO
# find out how yum parses groups and reimplement that in ruby
def self.instances
groups = []
# get list of all groups
yum_content = yum('grouplist').split("\n")
# turn of collecting to avoid lines like 'Loaded plugins'
collect_groups = false
# loop through lines of yum output
yum_content.each do |line|
# if we get to 'Available Groups:' string, break the loop
break if line.chomp =~ /Available Groups:/
# collect groups
if collect_groups and line.chomp !~ /(Installed|Available)/
current_name = line.chomp.sub(/^\s+/,'\1').sub(/ \[.*\]/,'')
groups << new(
:name => current_name,
:ensure => :present
)
end
# turn on collecting when the 'Installed Groups:' is reached
collect_groups = true if line.chomp =~ /Installed Groups:/
end
groups
end
def self.prefetch(resources)
instances.each do |prov|
if resource = resources[prov.name]
resource.provider = prov
end
end
end
def create
yum('-y', 'groupinstall', @resource[:name])
@property_hash[:ensure] == :present
end
def destroy
yum('-y', 'groupremove', @resource[:name])
@property_hash[:ensure] == :absent
end
def exists?
@property_hash[:ensure] == :absent
end
end
“模块名称/ lib /人偶/类型/yumgroup.rb”
Puppet::Type.newtype(:yumgroup) do
@doc = "Manage Yum groups
A typical rule will look like this:
yumgroup { 'Development tools':
ensure => present,
}
"
ensurable
newparam(:name) do
isnamevar
desc 'The name of the group'
end
end
然后,在启用pluginsync的情况下运行puppet agent,您可以使用以下自定义类型:
yumgroup {'Base': ensure => present, }
要么:
yumgroup {'Development tools': ensure => absent, }
您可以通过运行以下命令查看安装了哪些组:
puppet resource yumgroup
请享用!
这是“ yumgroup” p资源类型的定义。默认情况下,它将安装默认软件包和强制软件包,并可以安装可选软件包。
尽管很容易实现,但此定义尚不能删除yum组。我并不为自己烦恼,因为在某些情况下它可能导致木偶循环。
该类型需要安装yum-downloadonly rpm,我认为它只能在RHEL / CentOS / SL 6上运行。在我撰写本文时,yum在以前版本中的退出状态是错误的,因此“除非”参数不起作用而不扩展到grep输出。
define yumgroup($ensure = "present", $optional = false) {
case $ensure {
present,installed: {
$pkg_types_arg = $optional ? {
true => "--setopt=group_package_types=optional,default,mandatory",
default => ""
}
exec { "Installing $name yum group":
command => "yum -y groupinstall $pkg_types_arg $name",
unless => "yum -y groupinstall $pkg_types_arg $name --downloadonly",
timeout => 600,
}
}
}
}
我故意省略了使yum-downloadonly成为依赖项,因为它可能与其他人的清单冲突。如果要执行此操作,请在单独的清单中声明yum-downloadonly软件包,并将其包含在此定义中。不要直接在此定义中声明,否则,如果您多次使用此资源类型,则人偶将给出错误消息。然后,exec资源应要求Package ['yum-downloadonly']。
class yum_groupinstalls { yumgroup { '"Development tools"': } }
在定义中,我必须指定yum的完整路径,在CentOS 6.2上对我来说是/ usr / bin / yum。
我在Puppet类型参考中找不到Package类型的任何内容,所以我在Freenode的Puppet IRC频道上问(奇怪的是#puppet),却一无所获,所以我认为答案是“还没有”。
您可以通过Puppet Exec Type来执行此操作以执行必要的组安装。我肯定会包括一个商品onlyif
或unless
选项,以便它仅在需要时执行,或设置为refreshonly
并通过触发它,Notify
以便它不会每次都运行。该Exec
类型将在您触发的情况下在p客户端上本地执行命令。
我喜欢使用自定义资源的解决方案,但是它不是幂等的。我认为存在吗?功能:
Puppet::Type.type(:yumgroup).provide(:default) do
desc 'Support for managing the yum groups'
commands :yum => '/usr/bin/yum'
# TODO
# find out how yum parses groups and reimplement that in ruby
def self.instances
groups = []
# get list of all groups
yum_content = yum('grouplist')
# turn of collecting to avoid lines like 'Loaded plugins'
collect_groups = false
# loop through lines of yum output
yum_content.each do |line|
# if we get to 'Available Groups:' string, break the loop
break if line.chomp =~ /Available Groups:/
# collect groups
if collect_groups and line.chomp !~ /(Installed|Available)/
current_name = line.chomp.sub(/^\s+/,'\1').sub(/ \[.*\]/,'')
groups << new(
:name => current_name,
:ensure => :present
)
end
# turn on collecting when the 'Installed Groups:' is reached
collect_groups = true if line.chomp =~ /Installed Groups:/
end
groups
end
def self.prefetch(resources)
instances.each do |prov|
if resource = resources[prov.name]
resource.provider = prov
end
end
end
def create
yum('-y', 'groupinstall', @resource[:name])
@property_hash[:ensure] == :present
end
def destroy
yum('-y', 'groupremove', @resource[:name])
@property_hash[:ensure] == :absent
end
def exists?
cmd = "/usr/bin/yum grouplist hidden \"" + @resource[:name] + "\" | /bin/grep \"^Installed\" > /dev/null"
system(cmd)
$?.success?
end
end
yum_content = yum('grouplist')
需要一个,.split("\n")
以便.each
不会导致错误。
