简介

Redis 是一个高性能的key-value数据库。

准备

1. 下载：http://redis.io/download 下载 redis-3.2.0.tar.gz 的文件
2. 系统环境 yum -y install gcc-c++ tcl

安装

1. install redis

tar xzf redis-3.2.0.tar.gz
    cd redis-3.2.0
    ./configure
    make && make test
    make install

服务配置

1. 设置为服务

   保存以下代码到/etc/init.d/redis (在utils/redis_init_script脚本基础上修改的)

#!/bin/sh
#
# chkconfig:   2345 90 10
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis.pid
CONF="/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
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist,process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

2. 默认配置文件

mkdir -p /etc/redis
    cp redis.conf /etc/redis
    vi /etc/redis/redis.conf
    把 daemonize no 一行换成
    daemonize yes

3. 设置开机启动

chkconfig --add redis 
    chkconfig redis on #设置开机启动
    service redis start

配置文件详解

基本使用

1. redis 目录相关可执行文件列表

/usr/local/bin/redis-benchmark  ## 性能测试工具
/usr/local/bin/redis-check-aof  ## 用于修复出问题的AOF文件
/usr/local/bin/redis-check-dump ## 用于修复出问题的dump.rdb文件
/usr/local/bin/redis-check-rdb  ## 用于修复出问题的rdb文件
/usr/local/bin/redis-cli        ## 客户端程序
/usr/local/bin/redis-server     ## 服务端程序

2. 测试连接

[root@vagrant-centos64 /]# ./usr/local/bin/redis-cli 
127.0.0.1:6379> set ff aaa
OK
127.0.0.1:6379> get ff
"aaa"
127.0.0.1:6379> set key value [EX seconds] [PX milliseconds] [NX|XX]
