解决 MongoDB 一些的警告信息

MongoDB 一些比较烦人的警告信息

---

比如 /sys/kernel/mm/transparent_hugepage/defrag is 'always' ：

CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.
CONTROL  [initandlisten] **        We suggest setting it to 'never'
CONTROL  [initandlisten]

解决 ：

sudo apt install sysfsutils

echo "kernel/mm/transparent_hugepage/enabled = never" >> /etc/sysfs.conf
echo "kernel/mm/transparent_hugepage/defrag = never" >> /etc/sysfs.conf

 /etc/init.d/sysfsutils restart
