启动mongodb时提示下方信息

只需打开/etc/init/mongod.conf文件，将下方的代码添加到chown $DEAMONUSER /var/run/mongodb.pid 和
end script.之间即可，注意空格的对齐。
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then echo never > /sys/kernel/mm/transparent_hugepage/enabled fi if test -f /sys/kernel/mm/transparent_hugepage/defrag; then echo never > /sys/kernel/mm/transparent_hugepage/defrag fi
然后重启mongod服务
deng@deng-Lenovo:~$ sudo service mongod restart mongod stop/waiting mongod start/running, process 26127 deng@deng-Lenovo:~$ mongo MongoDB shell version: 3.0.4 connecting to: test >
