1、問題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.
出現如上錯誤是因為磁碟無法寫入,緣由:應該是之前強制停止redis快照導致
我的解囧,重啟機器沒問題了,哈哈哈,就是因為幾次強制停止造成的
有人的解囧如下
config set stop-writes-on-bgsave-error no
如果是記憶體問題應該如下辦法,具體查看日誌,
請在/etc/sysctl.conf 添加一項 ‘vm.overcommit_memory = 1‘ ,然後重啟(或者運行命令‘sysctl vm.overcommit_memory=1‘ )使其生效。
