#yum install gcc jemalloc-devel

# mkdir -p /data/app/redis/

# cd redis-3.0.2

# make PREFIX=/data/app/redis #編譯

# make PREFIX=/data/app/redis install #安裝

# mkdir -p /data/app/redis/{conf,var} #建立目錄存放配置文件和持久化數據及日誌

• 編輯配置文件

# vi /data/app/redis/conf/redis.conf

daemonize yes
pidfile "/data/app/redis/var/redis.pid"
port 6379
timeout 300
loglevel debug
logfile "/data/app/redis/var/redis.log"
databases 16
slave-read-only no
save 900 5
save 300 50
save 60 50000
rdbcompression yes
dbfilename "dump.rdb"
dir "/data/app/redis/var"
appendonly no
appendfsync always
maxmemory 1gb

####系統優化 redis在持久化舊數據的時候會使用雙倍內存，最好實際內存爲配置的maxmemory的2倍以上，而且容許overcommitmemory # sysctl -a|grep overcommit_memory|grep 0$ && echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf && sysctl -p

####啓動redis # /data/app/redis/bin/redis-server /data/app/redis/conf/redis.conf

####使用cli查看redis # /data/app/redis/bin/redis-cli info
