题

我已经任意了模板mysql的my.cnf，在尝试使用puppet中标准化从站数据库中的配置。现在，我针对InnoDB设置。 是否有配置选项，可以安全地计算硬件规范，例如内存，磁盘和procs？

有帮助吗？

解决方案

You need facter.

puppet:/etc/puppet/modules/master/lib/facter$ cat disks.rb
#!/usr/bin/ruby
#require 'facter'

mount = `/bin/mount`
disks=Array.new 
mount.split("\n").each_with_index { | disk,i |
  unless disk.scan(/ext3|simfs|reiserfs|xfs/).empty?
    d=disk.split[2]
    disks.push d
    disks.push ','
 end
}

Facter.add('disks') do
 setcode do
   disks
 end 
end

` and in puppet.pp i use facts $disks

#add disk check to zabbix
exec { "create_host":
    command => "/bin/echo $fqdn $ipaddress $disks | do_work",
    require => File["/root/ticket"],
    subscribe => File["/root/ticket"],
    refreshonly => true,
}

see "Adding Custom Facts to Facter" on puppet labs.

其他提示

I'd be tempted to move the calculations into the erb file, for example the key_buffer_size is recommended to be set to 1/4 of the Systems RAM:

set-variable = key_buffer_size=<%= (memorysize.split(' ')[0].to_i * 1024) / 4 -%>M

there is no reason why you couldn't work on other variables available from Facter (number of processors etc) and come up with your own calculations to set other variables as above.

Remember ERB effectively provides a subset of Ruby so almost anything you can do in Ruby can be done in ERB.

puppet have the erb template, erb template can use the facter value ,like hostname or memor. and you can write you self facter shell script.
