安裝使用Redis

標籤：redis

Redis最新版本是2.8.19

cd /data/app_software/

wget http://download.redis.io/releases/redis-2.8.19.tar.gz

tar zxvf redis-2.8.19.tar.gz

make

mkdir -p /data/app_platform/redis/{bin,conf}

cp src/redis-server /data/app_platform/redis/bin/

cp src/redis-cli /data/app_platform/redis/bin/

cp src/redis-benchmark /data/app_platform/redis/bin/

cp src/redis-check-dump /data/app_platform/redis/bin/

cp src/redis-check-aof /data/app_platform/redis/bin/

cp redis.conf /data/app_platform/redis/conf/

修改/data/app_platform/redis/conf/redis.conf配置,具體配置根據各自需要進行設定

redis 2.8中新增加的配置

添加開機檔案/etc/init.d/redis

啟動Redis後查看下日誌

chkconfig --level 35 redis on

service redis start

根據日誌提示調整系統配置

echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf ;sysctl -p

echo never > /sys/kernel/mm/transparent_hugepage/enabled   並且把這行添加到/etc/rc.local中使主機重啟後仍然生效

echo "net.core.somaxconn = 2048" >> /etc/sysctl.conf;sysctl -p

然後再重新啟動Redis
