centos6.8安装redis

1、下载Redis3.2.5安装包

cd /opt
wget http://download.redis.io/releases/redis-3.2.5.tar.gz

2、解压、编译、安装redis-3.2.5

tar -zxvf redis-3.2.5.tar.gz -C /usr/src/
cd /usr/src/redis-3.2.5/
make && make install

3、创建redis相关目录

mkdir -p /home/redis/bin
mkdir -p /home/redis/log
mkdir -p /home/redis/pid
mkdir -p /home/redis/db

4、将可执行文件复制到自己的安装目录：/home/redis/

 ln -s /usr/local/bin/redis-*   /home/redis/bin/

5、复制配置文件到自己的安装目录：/home/redis/

cp redis.conf /home/redis/

6、进入自己的安装目录，编辑redis.conf配置文件

cd /home/redis/
vim /home/redis/redis.conf

根据实际需要修改配置文件，以下仅供参考
daemonize yes
pidfile /home/redis/pid/redis.pid
logfile /home/redis/log/redis.log
dir /home/redis/db

7、创建redis服务脚本，并赋予权限

vim /etc/init.d/redis

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
PATH=/home/redis/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/home/redis/bin/redis-server
CLIEXEC=/home/redis/bin/redis-cli
PIDFILE=/home/redis/pid/redis.pid
CONF="/home/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

8、添加redis服务开机启动

chmod a+x /etc/init.d/redis

9、启动redis服务

service redis start
ps -ef | grep redis
netstat -anptu | grep 6379

10、测试OK

redis-cli
set key1 hello
get key1
quit

（防火墙启用6379端口：iptables -A INPUT -p tcp --dport 6379 -j ACCEPT）
