啟動mongodb時提示下方資訊

只需開啟/etc/init/mongod.conf檔案，將下方的代碼添加到chown $DEAMONUSER /var/run/mongodb.pid 和end script.之間即可，注意空格的對齊。

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

然後重啟mongod服務
