[5390] 19 Jun 21:07:07.690 # Server started, Redis version 2.6.14
[5390] 19 Jun 21:07:07.692 # WARNING overcommit_memory is set to 0! Background save may fail
under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to
/etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this
to take effect.
[5390] 19 Jun 21:07:07.692 * The server is now ready to accept connections on port 6379
如果内存不够，执行：“sysctl vm.overcommit_memory=1”命令，可以放到/etc/sysctl.conf 中，也可在
命令行执行。
