-虽然不影响学习但是由于本菜的强迫症.....

#解决方法(其实本菜完全不知道这是在干嘛)

前两个警告：root权限下

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

第三个警告：

在/etc/security/limits.d/下修改文件99-mongodb-nproc.conf(如果没有则新建文件) 添加内容:

#mongodb set limits config
*  -  fsize        unlimited   # (file size)
*  -  cpu         unlimited   # (cpu time)
*  -  as           unlimited   # (virtual memory size)
*  -  nofile     64000        # (open files)
*  -  nproc     64000        # (processes/threads)

然后重启mongoDB再进入mongo shell警告消失
