# 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.

# warning 3
# WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled

编译的几种方式

强制使用 libc malloc 的编译

% make MALLOC=libc 或者 make USE_JEMALLOC=no

使用 jemalloc 编译

% make 或 MALLOC=jemalloc 或者 make USE_JEMALLOC=yes

使用 tcmalloc 编译

% make MALLOC=tcmalloc 或者 make USE_JEMALLOC=yes

运行 redis-server redis.conf

清除编译方法

make distclean
