monitのrecipe

pidファイルをチェックするタイプのmonit.confを一気に作りたいとき。

recipes/defualt.rb

service "monit" do
  action :nothing
end

common_process = ["ntpd", "sshd", "crond"]

common_process.each do |proc|
  template "/etc/monit.d/#{proc}.conf" do
source "monit_template.conf.erb"
owner "root"
group "root"
mode 0644
notifies :restart, "service[monit]"
variables ({
  :process_name => proc,
  :pidfile => "/var/run/#{proc}.pid",
  :program => "/etc/init.d/#{proc}",
  :restarts => 5,
  :cycles => 5
})
  end
end

templates/default/monittemplate.conf.erb

check process <%= @process_name %> with pidfile <%= @pidfile %>
start program = "<%= @program %> start"
stop program = "<%= @program %> stop"
if <%= @restarts %> restarts within <%= @cycles %> cycles then timeout

knife solo cook実行後

プロセスごとのconfigファイルが展開される

crond.conf

check process crond with pidfile /var/run/crond.pid
start program = "/etc/init.d/crond start"
stop program = "/etc/init.d/crond stop"
if 5 restarts within 5 cycles then timeout

ntpd.conf

check process ntpd with pidfile /var/run/ntpd.pid
start program = "/etc/init.d/ntpd start"
stop program = "/etc/init.d/ntpd stop"
if 5 restarts within 5 cycles then timeout

/etc/monit.d/sshd.conf

check process sshd with pidfile /var/run/sshd.pid
start program = "/etc/init.d/sshd start"
stop program = "/etc/init.d/sshd stop"
if 5 restarts within 5 cycles then timeout

楽ちん
