redis因为maxheap过大，启动失败的解决方法

今天在windows安装完redis启动时遇到一个错误：

D:\Program Files\redis\Redis-x64-2.8.2104>redis-server redis.windows.conf
[5984] 23 Sep 12:29:47.730 #
The Windows version of Redis allocates a memory mapped heap for sharing with
the forked process used for persistence operations. In order to share this
memory, Windows allocates from the system paging file a portion equal to the
size of the Redis heap. At this time there is insufficient contiguous free
space available in the system paging file for this operation (Windows error
0x5AF). To work around this you may either increase the size of the system
paging file, or decrease the size of the Redis heap with the --maxheap flag.
Sometimes a reboot will defragment the system paging file sufficiently for
this operation to complete successfully.

Please see the documentation included with the binary distributions for more
details on the --maxheap flag.

Redis can not continue. Exiting.

大概意思是：没有足够的可用空间，可以增加系统的大小分页文件，或减少Redis的堆的大小。
解决方法：
使用--maxheap标志。
可以再启动命令后面加maxheap参数重新分配堆大小。
可以修改redis.windows.conf中maxheap的值为200m,这样问题就解决了。
