简介

Redis是一个开源（BSD许可），内存存储的数据结构服务器，是一个高性能的key-value数据库，高速缓存和消息队列代理。它支持字符串、哈希表、列表、集合、有序集合，位图，hyperloglogs等数据类型。内置复制、Lua脚本、LRU收回、事务以及不同级别磁盘持久化功能，同时通过Redis Sentinel提供高可用，通过Redis Cluster提供自动分区。

下载与安装

wget http://download.redis.io/releases/redis-4.0.1.tar.gztar xzf redis-4.0.1.tar.gzcd redis-4.0.1makemake isntall

服务管理

通过指定配置文件启动

sudo redis-server /opt/redis-4.0.1/redis.conf

22090:C 20 Sep 09:52:39.951 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

22090:C 20 Sep 09:52:39.951 # Redis version=4.0.1, bits=64, commit=00000000, modified=0, pid=22090, just started

22090:C 20 Sep 09:52:39.951 # Configuration loaded

如果输出如上信息，证明Redis服务已经启动成功。

通过命令redis-server 启动

redis-server

关闭Redis服务

redis-cli shutdown

客户端登陆并验证

redis-cli

127.0.0.1:6379> set a b

OK

127.0.0.1:6379> get a

"b"

127.0.0.1:6379> exit

设置redis开机启动

创建Redis配置目录

sudo mkdir /etc/redis

拷贝配置文件

sudo cp /opt/redis-4.0.1/redis.conf /etc/redis/

修改目录/etc/redis/下面的redis.conf文件，将以下内容

> daemonize no> logfile ""

修改为：

#打开后台运行选项

daemonize yes

#设置日志文件路径

logfile "/var/log/redis/redis.log"

#!/bin/sh# chkconfig: 2345 10 90# description: Start and Stop redisPATH=/usr/local/binREDISPORT=6379EXEC=/usr/local/bin/redis-serverREDIS_CLI=/usr/local/bin/redis-cliPIDFILE=/var/run/redis.pidCONF="/etc/redis/redis.conf"case "$1" in    start)        if [ -f $PIDFILE ]        then            echo "$PIDFILE exists, process is already running or crashed."        else            echo "Starting Redis server..."            $EXEC $CONF        fi        if [ "$?"="0" ]        then            echo "Redis is running..."        fi        ;;    stop)        if [ ! -f $PIDFILE ]        then            echo "$PIDFILE exists, process is not running."        else            PID=$(cat $PIDFILE)            echo "Stopping..."            $REDIS_CLI -p $REDISPORT SHUTDOWN            while [ -x $PIDFILE ]            do                echo "Waiting for Redis to shutdown..."                sleep 1            done            echo "Redis stopped"        fi        ;;    restart|force-reload)          ${0} stop          ${0} start        ;;    *)        echo "Usage: /etc/init.d/redis {start|stop|restart|fore-reload}"        exit 1esac

使用脚本启动服务

• 开启redis：service redis start
• 停止redis： service redis stop
• 重启redis： service redis restart
• 查看服务状态：service redis status
