redis启动报错：The Windows version of Redis allocates a memory mapped heap for sharing with-优快云博客

当Redis启动报错提示内存不足时，可以通过调整系统分页文件大小或限制Redis堆大小来解决。通过命令`redis-server.exe --maxheap 10240000`（可自定义大小）能成功启动Redis。

windows系统下通过cmd命令：redis-server.exe redis.windows.conf 启动redis报错，控制台报错如下：

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.

这个情况明显是内存溢出，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。

我们使用命令：redis-server.exe --maxheap 10240000（大小自己设置就好）就可以正常启动redis。
