后记:不过这也不是一个错误,只不过是fact fqdn取不出来报的一个警告信息,如果你不管也没关系,只不过在message中会不停的多出这些垃圾信息,时间长了挺占空间的,呵呵!

这几天公司一个同事在研究puppet的过程中 puppetmaster端的日志里面老是报hostname错误,×××找了点资料并查看了源代码,最终解决了此类问题,特此分享!
以下是puppetmaster端 /var/log/message中报的信息
Mar 24 03:15:17 puppet-master puppet-master[26327]: Host is missing hostname and/or domain: www.app-node3.comMar 24 03:15:17 puppet-master puppet-master[26327]: Compiled catalog for www.app-node3.com in environment production in 0.08 secondsMar 24 03:15:30 puppet-master puppet-master[26327]: Host is missing hostname and/or domain: www.app-node3.comMar 24 03:15:30 puppet-master puppet-master[26327]: Compiled catalog for www.app-node3.com in environment production in 0.05 secondsMar 24 03:15:43 puppet-master puppet-master[26327]: Host is missing hostname and/or domain: www.app-node3.comMar 24 03:15:43 puppet-master puppet-master[26327]: Compiled catalog for www.app-node3.com in environment production in 0.05 secondsMar 24 03:15:48 puppet-master puppet-master[26327]: Host is missing hostname and/or domain: www.app-node3.comMar 24 03:15:48 puppet-master puppet-master[26327]: Compiled catalog for www.app-node3.com in environment production in 0.05 seconds
初步分析一:
从错误分析来看应该是主机名或者域名有问题导致的, 而客户的主机名为puppet-master,certname为puppet-master.puppet.com,查过一些资料发现,puppet不允许命名自己的certname为puppet,puppet.com,所以导致了此类问题。
更改为其它名称后故障依旧
继续分析二:
既然报同样的错误 “Host is missing hostname and/or domain:”,说明这关键词在代码中是存在的,那么就分析代码吧。
1、首先先查找这段关键词在那个文件中
[root@puppetmaster ~]# grep "Host is missing hostname" `rpm -ql puppet`grep: /etc/puppet/puppetca.conf: No such file or directorygrep: /etc/puppet/puppetd.conf: No such file or directory/usr/lib/ruby/site_ruby/1.8/puppet/node.rb: Puppet.warning "Host is missing hostname and/or domain: #{name}"
2、查看代码报错原因
[root@puppetmaster ~]# vim /usr/lib/ruby/site_ruby/1.8/puppet/node.rb112 # First, get the fqdn113 unless fqdn = parameters["fqdn"]114 if parameters["hostname"] and parameters["domain"]115 fqdn = parameters["hostname"] + "." + parameters["domain"]116 else117 Puppet.warning "Host is missing hostname and/or domain: #{name}"118 end119 end120121 # Now that we (might) have the fqdn, add each piece to the name122 # list to search, in order of longest to shortest.
原因很简单,代码的意思是为了保证另外一个fact fqdn的存在,只有当hostname和domain两个fact都存在的情况下才可以,否则就会报错Puppet.warning "Host is missing hostname and/or domain: #{name}"
3、再次验证原因
从以下可以看出节点只能过来出来fact hostname
[root@puppetmaster ~]# facter | egrep -i 'hostname|domain|fqdn'hostname => puppetmaster
1、所有节点/etc/resolve.conf中加上domain
[root@puppetmaster ~]# vim /etc/resolv.conf; generated by /sbin/dhclient-script#nameserver 202.96.209.5#nameserver 202.96.209.133domain lixs.com
再次验证
[root@puppetmaster ~]# facter | egrep -i 'hostname|domain|fqdn'domain => lixs.comfqdn => puppetmaster.lixs.comhostname => puppetmaster
2、修改node.rb代码,然后通过file资源推下去
2.1、删除以下代码
删除之后,就不存在fqdn这个fact了
# First, get the fqdnunless fqdn = parameters["fqdn"] if parameters["hostname"] and parameters["domain"] fqdn = parameters["hostname"] + "." + parameters["domain"] else Puppet.warning "Host is missing hostname and/or domain: #{name}" endend
2.2、去掉if判断语句,设置fqdn = 你设置的值
比如自定义的certname,不过节点一定要有自己设置的fact哦。
# First, get the fqdnunless fqdn = parameters["fqdn"] fqdn = parameters["fact_certname"]end
后记:不过这也不是一个错误,只不过是fact fqdn取不出来报的一个警告信息,如果你不管也没关系,只不过在message中会不停的多出这些垃圾信息,时间长了挺占空间的,呵呵!
