一、安装Redis

1.创建redis用户组和用户

groupadd redis
useradd -r -g redis -s /sbin/nologin -M redis

2.下载redis源码包，将源码包放到/usr/local/src/目录下

下载页面：http://redis.io/download
这里用的是redis-3.2.5.tar.gz
下载地址：http://download.redis.io/releases/redis-3.2.5.tar.gz

3.进入src/目录

cd /usr/local/src/

4.解压源码包

tar -zxf redis-3.2.5.tar.gz

5.进入redis源码目录，编译安装

cd redis-3.2.5/

make PREFIX=/usr/local/redis install

6.创建redis文件目录

mkdir -p /usr/local/redis/data
mkdir -p /usr/local/redis/etc
mkdir -p /var/run/redis
mkdir -p /var/log/redis

7.将配置文件放入redis/etc/目录

cp redis.conf /usr/local/redis/etc/

8.修改redis配置文件redis.conf

vim /usr/local/redis/etc/redis.conf

9.修改为下面内容，保存退出

#tcp队列长度，CentOS系统默认为128，此值不应该大于操作系统的该值
tcp-backlog 128
#改为yes，保证redis可以后台运行
daemonize yes
#redis pid
pidfile /var/run/redis/redis.pid
#redis日志
logfile "/var/log/redis/redis.log"
#redis数据存储目录
dir /usr/local/redis/data/

10.修改redis目录权限

chown -R redis:redis /usr/local/redis
chown -R redis:redis /var/run/redis
chown -R redis:redis /var/log/redis

11.将redis命令加入环境变量，修改profile文件

vim /etc/profile

12.修改为下面内容，保存退出

PATH=/usr/local/mysql/bin:/usr/local/php/bin:/usr/local/redis/bin:$PATH

13.使/etc/profile里的配置立即生效

source /etc/profile

14.将redis服务脚本加入到init.d/目录，创建redisd文件

vim /etc/init.d/redisd

15.加入下面内容，保存退出

function start() {
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo -n "Starting Redis server..."
                daemon --user=redis --pidfile=$PIDFILE $EXEC $CONF
                #$EXEC $CONF
                echo
        fi
}
function stop() {
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                #$CLIEXEC -p $REDISPORT shutdown
                killproc -p $PIDFILE $EXEC -INT
                echo -n "Waiting for Redis saving data & shutdown ."
                while [ -x /proc/${PID} ]
                do
                    sleep 1
                    echo -n "."
                done
                echo -e "\nRedis stopped"
        fi
}
 
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    status)
        status -p $PIDFILE $EXEC
        ;;
    restart)
        stop
        start
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;

16.为redisd添加可执行权限

chmod +x /etc/init.d/redisd

17.将redis加入系统服务

chkconfig --add redisd

18.设置开机启动

chkconfig redisd on

19.启动redis

service redisd start

二、PHP7安装Redis拓展

1.yum安装git

yum -y install git

2.进入src/目录

cd /usr/local/src/

3.git下载phpredis拓展

git clone https://github.com/phpredis/phpredis.git

4.进入phpredis/目录

cd phpredis/

5.默认clone的php5的redis扩展，需要切换到php7的分支

git checkout php7

6.编译安装拓展

phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install

7.修改php.ini文件

vim /usr/local/php/etc/php.ini

8.添加redis.so扩展配置，保存退出

extension=redis.so;

9.重启Apache或php-fpm

service httpd restart
service php-fpm restart

10.在web目录下添加php文件，如 在web目录下添加php文件，如/usr/local/apache/htdocs/redis.php 或 /usr/local/nginx/html/redis.php

<?php
$redis = new Redis();
$redis->connect(‘127.0.0.1‘, 6379);
$redis->set(‘class‘,‘toefl‘);
print_r($redis->get(‘class‘));

访问URL，如：http://192.168.8.9/redis.php
页面显示正常，则配置成功
