    Redis安装

    1,安装redis

    cd
    wget http://download.redis.io/releases/redis-3.0.5.tar.gz
    tar -zxvf redis-3.0.5.tar.gz
    cd redis-3.0.5
    make
    cd src
    make install PREFIX=/usr/local/redis
    cd ..
    mkdir /usr/local/redis/etc
    cp redis.conf /usr/local/redis/etc/redis.conf

    批处理:
    cd && wget http://download.redis.io/releases/redis-3.0.5.tar.gz && tar -zxvf redis-3.0.5.tar.gz && cd redis-3.0.5 && make && cd src && make install PREFIX=/usr/local/redis && cd .. && mkdir /usr/local/redis/etc && cp redis.conf /usr/local/redis/etc/redis.conf

    2、默认情况,Redis不是在后台运行,需要把redis放在后台运行:

    vi /usr/local/redis/etc/redis.conf
    将daemonize的值改为yes

    2.1 如果redis需要设密码,改:

    requirepass 【密码】

    3,启动Redis:

    /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

    前两项批处理:
    sed -i 's/^\(daemonize\).*/\1 yes/' /usr/local/redis/etc/redis.conf
    echo '/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf' >> /etc/rc.d/rc.local

    到这里Redis安装完成,

    4,连接客户端:

    /usr/local/redis/bin/redis-cli

    127.0.0.1:6379> ping        ---这说明已经成功地安装Redis在机器上
    PONG
    127.0.0.1:6379> keys *                     --列出所有键名
    (empty list or set)                            --若出现这个,表示安装正常。
    127.0.0.1:6379>keys flushdb         --清空,好象不起作用

    5,停止(只是说明如何停止,这里不必须停止):

    /usr/local/redis/bin/redis-cli shutdown

    6,安装PHP扩展:

    相关步骤:
    cd /usr/local/src                                                                                         #进入软件包存放目录
    wget https://github.com/nicolasff/phpredis/archive/2.2.4.tar.gz           #下载安装包,或都其他方式下载并上传phpredis-2.2.4.tar.gz到/usr/local/src目录
    tar zxvf 2.2.4.tar.gz                                                                                     #解压
    cd phpredis-2.2.4                                                                                         #进入安装目录
    /usr/local/php/bin/phpize                                                                         #用phpize生成configure配置文件
    ./configure --with-php-config=/usr/local/php/bin/php-config             #配置
    make                                                                                                             #编译
    make install                                                                                                 #安装

    PHP7:
    cd && wget -c https://github.com/phpredis/phpredis/archive/php7.zip && unzip php7.zip && cd phpredis-php7 && /usr/local/php/bin/phpize && ./configure --with-php-config=/usr/local/php/bin/php-config && make && make install && make test

    PHP7以下:
    cd && wget https://github.com/nicolasff/phpredis/archive/2.2.4.tar.gz && tar zxvf 2.2.4.tar.gz && cd phpredis-2.2.4 && /usr/local/php/bin/phpize && ./configure --with-php-config=/usr/local/php/bin/php-config && make && make install && make test

    安装完成之后,出现下面的内容表示安装完成,需要配置PHP.ini:

    +-----------------------------------------------------------+
    | ! ERROR !                                                                         |
    | The test-suite requires that proc_open() is available.  |
    | Please check if you disabled it in php.ini.                     |
    +-----------------------------------------------------------+

    7,配置php支持

    vi /usr/local/php/etc/php.ini

    修改:先搜索有没有此项

    extension="redis.so"                                             #WIN中是: extension=php_redis.dll
    session.save_handler = redis                                 #原值:files
    session.save_path = “tcp://127.0.0.1:6379″         #原值:/tmp,且未启用
    session.auto_start = 0                                             #原值:0

    sed -i '/Module Settings/i ; redis & scwc\n;;;;;;;;;;;;;;;;;;;\nextension=redis.so\n;;;;;;;;;;;;;;;;;;;' /usr/local/php/etc/php.ini
    sed -i 's/^\(session.save_handler\).*/\1=redis/' /usr/local/php/etc/php.ini
    sed -i 's/^;\(session.save_path\).*/\1="tcp:\/\/127.0.0.1:6379"/' /usr/local/php/etc/php.ini
    sed -i 's/^\(session.auto_start\).*/\1=0/' /usr/local/php/etc/php.ini                                                                                                                                                                                                                              

    如果不想修改php.ini可这样
    ini_set("session.save_handler","redis");
    ini_set("session.save_path","tcp://127.0.0.1:6379″);
    如果配置文件/etc/redis.conf里设置了连接密码requirepass保存session的时候会报错,save_path这样写 tcp://127.0.0.1:6379?auth=authpwd 即可。
    有网友提到相对于文件存储的session,redis或者memcache存储session值会有并发一致性的问题,这块并没有细测过。

    8,重启,直接lnmp restart

    如果Redis没有起作用,php -m查看是否加载成功。

    9,测试PHP读写:

    vi /home/wwwroot/default/redis.php

    <?php
    session_start();
    $_SESSION['redis'] = "test redis". time();
    echo "Redis session_id:\t\t\t".session_id()."<br>";
    echo "刚存入的值:\t\t\t".$_SESSION['redis']."<br>";
    $redis = new redis();
    $redis->connect('127.0.0.1', 6379);
    echo "上一次的存入值:\t\t\t". $redis->get("PHPREDIS_SESSION:".session_id());

    打开:http://192.168.2.122/redis.php 显示以下内容表示一切正常。
    session_id:2ieemhttqhjt3mt46fb2sqbkr4
    value:test redis
    Redis:redis|s:10:"test redis";

    /usr/local/redis/bin/redis-cli

    127.0.0.1:6379> keys *
    1) "PHPREDIS_SESSION:2ieemhttqhjt3mt46fb2sqbkr4"
    127.0.0.1:6379>

    完整批处理

    cd && wget http://download.redis.io/releases/redis-3.0.5.tar.gz && tar -zxvf redis-3.0.5.tar.gz && cd redis-3.0.5 && make && cd src && make install PREFIX=/usr/local/redis && cd .. && mkdir /usr/local/redis/etc && cp redis.conf /usr/local/redis/etc/redis.conf && cd /usr/local/src && wget https://github.com/nicolasff/phpredis/archive/2.2.4.tar.gz && tar zxvf 2.2.4.tar.gz && cd phpredis-2.2.4 && /usr/local/php/bin/phpize && ./configure --with-php-config=/usr/local/php/bin/php-config && make && make install && make test

    vi /usr/local/redis/etc/redis.conf        将daemonize的值改为yes

    vi /usr/local/php/etc/php.ini
    extension="redis.so"                                             #WIN中是: extension=php_redis.dll
    session.save_handler = redis                                 #原值:files
    session.save_path = “tcp://127.0.0.1:6379″         #原值:/tmp,且未启用

    vi /etc/rc.d/rc.local
    /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
