1、问题MISCONF Redis is configured to save RDB snapshots

127.0.0.1:6379> set k1 "nob"

(error) MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error.

出现如上错误是因为磁盘无法写入，缘由：应该是之前强制停止redis快照导致

我的解囧，重启机器没问题了，哈哈哈，就是因为几次强制停止造成的

有人的解囧如下

config set stop-writes-on-bgsave-error no

如果是内存问题应该如下办法，具体查看日志，

请在/etc/sysctl.conf 添加一项 ‘vm.overcommit_memory = 1‘ ，然后重启（或者运行命令‘sysctl vm.overcommit_memory=1‘ ）使其生效。
