安装MONGODB 3.0.6的时候提示警告信息，如下：

2015-09-09T11:04:35.011+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is ‘always‘.
2015-09-09T11:04:35.011+0800 I CONTROL [initandlisten] ** We suggest setting it to ‘never‘
2015-09-09T11:04:35.011+0800 I CONTROL [initandlisten]
2015-09-09T11:04:35.011+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is ‘always‘.
2015-09-09T11:04:35.011+0800 I CONTROL [initandlisten] ** We suggest setting it to ‘never‘
2015-09-09T11:04:35.011+0800 I CONTROL [initandlisten]

有人说，执行如下命令：
echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
echo "never" > /sys/kernel/mm/transparent_hugepage/defrag

但是，在执行之前去查看enabled和defrag文件的话，已经是never状态，因此根本不是这个问题。

最后确认发现是缺少了以下的依赖包，安装即可：
gcc-4.4.7-16.el6.x86_64.rpm
gcc-c++-4.4.7-16.el6.x86_64.rpm
libgcc-4.4.7-16.el6.x86_64.rpm
libgomp-4.4.7-16.el6.x86_64.rpm
libstdc++-4.4.7-16.el6.x86_64.rpm
libstdc++-devel-4.4.7-16.el6.x86_64.rpm
