[root@localhost202 redis-2.8.19]#/usr/local/redis/bin/redis-server >>/data/redis-start.txt#は指向性からファイルまで、簡単に見ることができます.内容は以下の通りです.
[root@localhost202 redis-2.8.19]# cat/data/redis-start.txt
1、プロファイルの追加
2、maxmemoryの配置
3、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.
構成:メモリがいっぱいになることによるシステムのクラッシュを防止するために/etc/redis/*を設定する必要がある.cnfのmaxmemory エラーを防止し、メモリ割り当てポリシー を調整できます.
