redis的安装方法详解

安装环境准备

1.安装gcc：yum install gcc

2.安装zlib：yum install zlib zlib-devel

3.安装tcl：yum install tcl

4.安装OpenSSL：yum install openssl openssl-devel

安装Redis

1.下载Redis：wget http://download.redis.io/releases/redis-3.2.9.tar.gz

2.解压Redis：tar -zxvf redis-3.2.9.tar.gz

3.进入解压目录：cd redis-3.2.9

4.编译安装：make MALLOC=libc

5.安装：make install

配置Redis

1.将Redis拷贝到指定目录：cp redis.conf /etc/redis/

2.修改Redis配置文件：vi /etc/redis/redis.conf

# 指定redis的运行模式
# 默认为standalone模式
# 如果要使用集群模式，需要修改为cluster
# 或者sentinel模式
# 或者多主复制模式
# 或者哨兵模式
# 或者主从复制模式
# 或者主从复制Sentinel模式
# 或者主从复制多主模式
# 或者主从复制多主Sentinel模式
# 或者主从复制多主多从模式
# 或者主从复制多主多从Sentinel模式
# 或者主从复制多主多从多Sentinel模式
mode standalone

3.启动Redis：/usr/local/bin/redis-server /etc/redis/redis.conf

4.测试Redis：/usr/local/bin/redis-cli

设置Redis开机启动

1.编辑redis.conf文件：vi /etc/redis/redis.conf

# 设置开机启动
daemonize yes

2.添加Redis服务：vi /etc/init.d/redis

#!/bin/sh
# chkconfig: 2345 10 90
# description: Redis service
#
# Redis is an open source, advanced key-value store.
#
# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CONF="/etc/redis/redis.conf"

PIDFILE=/var/run/redis_${REDISPORT}.pid

case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
            echo "$PIDFILE exists, process is already running or crashed"
        else
            echo "Starting Redis server..."
            $EXEC $REDIS_CONF
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
            echo "$PIDFILE does not exist, process is not running"
        else
            PID=$(cat $PIDFILE)
            echo "Stopping ..."
            $EXEC $REDIS_CONF stop
            while [ -x /proc/${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

3.设置Redis开机启动：chkconfig redis on

4.重启Redis服务：service redis restart

使用Redis

1.连接Redis服务：/usr/local/bin/redis-cli

127.0.0.1:6379> set name "redis"
OK
127.0.0.1:6379> get name
"redis"

2.使用Redis命令：

• KEYS：查找所有符合给定模式 pattern 的 key
• DEL：根据给定的key删除给定的值
• EXISTS：检查给定key是否存在
• EXPIRE：为给定key设置过期时间
• TTL：查看给定key的剩余生存时间
• PERSIST：移除给定key的过期时间
• SET：设置指定key的值
• GET：获取指定key的值
