[FAILED]
启动失败并报错
报错的重点是第一句，提示no such file to load -- json (LoadError)，意思好像是因为json没有安装，也有可能是没有可ruby关联上
解决办法：
重新安装json，
[root@puppetmaster ~]#
Fetching: json-1.8.1.gem (100%)
Building native extensions. This could take a while...
Successfully installed json-1.8.1
1 gem installed
Installing ri documentation for json-1.8.1...
Installing RDoc documentation for json-1.8.1...
重新启动puppet和puppetmaster成功！
