0、表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存，内存申请允许；否则，内存 申请失败，并把错误返回给应用进程。
1、表示内核允许分配所有的物理内存，而不管当前的内存状态如何
2、表示内核允许分配超过所有物理内存和交换空间总和的内存

vm.overcommit_memory = 12.2.2.3.3：transparent hugepage
WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis.

Redis must be restarted after THP is disabled.
警告：您在内核中启用了透明大页面（THP）支持。 这将在Redis中造成延迟和内存使用问题。 要解决此问题，请以根用户身份运行命令“echo never> / sys / kernel / mm / transparent_hugepage / enabled”，并将其添加到您的/etc/rc.local中，以便在重启后保留设置。 禁用THP后，必须重新启动Redis。
