php session存入redis
一、 安裝phpredis擴展
php連接redis需要安裝phpredis擴展。
下載地址：https://github.com/phpredis/phpredis/releases，選用相應版本。
筆者用的是php5.6.29，下載了phpredis-3.0.0安裝出了問題，於是換成phpredis-2.2.8，正常。
# tar zxvf phpredis-2.2.8.tar.gz && cd phpredis-2.2.8
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make && make install
正常情況下會提示在下面目錄下生成redis.so文件
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/
# sed -i ‘$aextension="redis.so"‘ /usr/local/php/etc/php.ini
# service httpd restart
驗證：
# php -i | grep redis | grep -xq redis && echo ok || echo "phpredis extended failure"
二、 配置php連接redis(筆者使用的阿裏雲redis)
# sed -i ‘s/session.save_handler.*/session.save_handler = redis/‘ /usr/local/php/etc/php.ini
# sed -i ‘/session.save_handler/asession.save_path ="tcp://xxxx.rds.aliyuncs.com?auth=redis密碼"‘ /usr/local/php/etc/php.ini
# service httpd restart
三、 驗證session存儲
1. 測試文件
# cat test.php
<?php echo "what are you doing now?"; session_start(); $_SESSION[‘a‘] = ‘elisun‘; ?>
2. 訪問
# curl -I http://127.0.0.1/test.php
HTTP/1.1 200 OK

3. 連接redis查看該key
> get "PHPREDIS_SESSION:tgt25hi24qfjs2f289941g8pm0"
"a|s:6:\"elisun\";"
