如何查看单个进程的内存占用
redis 默认没有最大内存限制
By Default maxmemory has no limits on 64-bit redis installation and on 32-bit installation it is 3GB.
You can set/change memory limit used by redis by setting maxmemory variable in redis.conf at ,
“/etc/redis/redis.conf”
For example if you want to set it to 512mb, you need to make an entry in redis.conf , like :
maxmemory 512mb
