本次演示系统为Centos7，安装的版本为redis-6.2.7

1.下载安装包并解压到/usr/local,redis的下载地址 
https://redis.io/download/

# wget https://download.redis.io/releases/redis-6.2.7.tar.gz
# tar -zxvf redis-6.2.7.tar.gz -C /usr/local/

2.安装redis编译所需插件

# yum -y install gcc automake autoconf libtool make

3.编译安装make编译 make install安装 PREFIX指定安装目录

# cd /usr/local/redis-6.2.7
# make && make PREFIX=/usr/local/redis-6.2.7 install

4.运行redis，看到redis运行动画以后代表安装成功

# cd bin && ./redis-server

基础配置

#bind 代表可访问id，设置为*则允许所有ip访问
bind 127.0.0.1 -::1
#保护模式 默认外网是访问不了的，如需外网访问请设置为no，建议使用ssh进行连接redis 比较安全
protected-mode yes
#端口号
port 6379
#客户端闲置多久以后关闭 为0则不关闭
timeout 0
#是否以守护进程运行，windows不支持守护进程
daemonize yes
#日志记录的等级
loglevel notice
#redis库数量，默认16
databases 16
#redis连接访问的密码，默认是关闭的，建议开启
requirepass foobared

配置开启自启动，这样服务器宕机重启以后会自动开启

编辑vim /etc/init.d/redis文件

把下方代码复制进去

#!/bin/sh
# description: Start and Stop redis   

REDISPORT=6379
EXEC=/usr/local/redis-6.2.7/src/redis-server
CLIEXEC=/usr/local/redis-6.2.7/src/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/local/redis-6.2.7/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
        ;;
    restart)
        "$0" stop
        sleep 3
        "$0" start
        ;;
    *)
        echo "Please use start or stop or restart as first argument"
        ;;
esac

将脚本添加到chkconfig，开机自启动

# chkconfig --add redis   //开启自启动
# chkconfig redis off     //关闭自启动
# chkconfig --del redis   //删除自启动
