mongodb

启动mongodb时出现下面的错误：

Server has startup warnings:

2016-11-28T00:46:04.682+0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.

请问如何解决？

方法一：

只需要在/etc/init/mongod.conf文件中添加如下代码到chown $DEAMONUSER /var/run/mongodb.pid 和end script.之间即可，注意空格的对齐。

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
   echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
   echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi

然后重启下服务器或mongod

方法二:

输入命令：vi /etc/rc.local

输入

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

重启服务器即可。
