1、安装redis

安装

tar -zxvf redis-2.6.17.tar.gz 
cp redis-2.6.17 /usr/local/redis
cd /usr/local/redis/
make && make install
vim redis.conf

修改配置

daemonize yes  #以守护进程方式运行 
dir /usr/local/redis  #使redis-server可在任意目录下执行
appendonly yes  #指定是否在每次更新操作后进行日志记录

开机自启动

服务脚本：

vim /etc/init.d/redis

脚本内容：

# chkconfig: 2345 10 90  
# description: Start and Stop redis   
  
PATH=/usr/local/bin:/sbin:/usr/bin:/bin   
REDISPORT=6379  
EXEC=/usr/local/bin/redis-server   
REDIS_CLI=/usr/local/bin/redis-cli   
 
PIDFILE=/var/run/redis.pid   
CONF="/usr/local/redis/redis.conf"  
AUTH="1234"  

case "$1" in   
        start)   
                if [ -f $PIDFILE ]   
                then   
                        echo "$PIDFILE exists, process is already running or crashed."  
                else  
                        echo "Starting Redis server..."  
                        $EXEC $CONF   
                fi   
                if [ "$?"="0" ]   
                then   
                        echo "Redis is running..."  
                fi   
                ;;   
        stop)   
                if [ ! -f $PIDFILE ]   
                then   
                        echo "$PIDFILE exists, process is not running."  
                else  
                        PID=$(cat $PIDFILE)   
                        echo "Stopping..."  
                       $REDIS_CLI -p $REDISPORT  SHUTDOWN    
                        sleep 2  
                       while [ -x $PIDFILE ]   
                       do  
                                echo "Waiting for Redis to shutdown..."  
                               sleep 1  
                        done   
                        echo "Redis stopped"  
                fi   
                ;;   
        restart|force-reload)   
                ${0} stop   
                ${0} start   
                ;;   
        *)   
               echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2  
                exit 1  
esac

设置开机自启动

chkconfig redis on

重启

reboot

连接

redis-cli

2、安装phpredis

下载

http://pecl.php.net/package/redis

安装

tar zxvf  redis-3.0.0.tgz
cd redis-3.0.0
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install

php添加redis扩展

find / -name php.ini
vim /usr/local/php/etc/php.ini

添加如下内容：

extension=redis.so

重启服务

service nginx restart
killall php-fpm
service php-fpm start

浏览器访问phpinfo.php即可看到有redis扩展了

new redis();

新建redis.php

$redis = new Redis();
var_dump($redis);
exit;
