Redis启动失败---内存不足

今天在配置SpringCloudGateway网关的时候，需要用到redis当限流的依赖。然后在window上启动

redis-server.exe redis.windows.conf

然后报错如下：

The Windows version of Redis allocates a memory mapped heap for sharing with the forked process used for persistence operations. 

C:\study\Redis\Redis-2.8_1>redis-server.exe redis.windows.conf [23452] 26 Aug 16:49:33.776 # 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.

经查，是因为系统内存不足引起的，可以通过添加启动参数解决：

redis-server.exe  redis.windows.conf  --maxheap 1gb

maxheap参数可以带单位也可以不带单位，不带单位默认为字节。
