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-backlog 128 #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
daemonize yes #改为yes，保证redis可以后台运行
pidfile /var/run/redis/redis.pid #redis pid
logfile "/var/log/redis/redis.log" #redis日志
dir /usr/local/redis/data/ #redis数据存储目录
#------ 可选配置 ------
#slaveof 192.168.1.66 6379 #主从复制，在副机上配置，例：IP 192.168.1.66，端口 6379
#save 60 10000 #快照，例：60s内10000个更改就保存
#appendonly yes #AOF持久化
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:$PATH
13.使/etc/profile里的配置立即生效
source /etc/profile
14.将redis服务脚本加入到init.d/目录，创建redisd文件
vim /etc/init.d/redisd
15.加入下面内容，保存退出
#!/bin/sh
#
# chkconfig: 35 84 16
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem. . /etc/rc.d/init.d/functions
. /etc/sysconfig/network [ "$NETWORKING" = "no" ] && exit 0 REDISPORT=6379
BASEDIR=/usr/local/redis
EXEC=$BASEDIR/bin/redis-server
CLIEXEC=$BASEDIR/bin/redis-cli PIDFILE=/var/run/redis/redis.pid
CONF="$BASEDIR/etc/redis.conf" 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"
;;
esac
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.修改服务的默认启动等级
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/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
Redis安装完毕！
