在使用codelgniter 中config/config.php 中 要把session 存储方式改为 redis 结果报错了！如下：
Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (.....) in Unknown on line 0$config['sess_save_path'] = 'tcp://127.0.0.1:6379';地址肯定是对的，也不需要auth , 使用redis-cli 也能连接到redis服务。
网上查了会，有说 是phpredis版本太低， 我的phpredis 扩展 版本 3.1.9 ；redis版本3.2.9; 虽然不一致，但也不低呀。
会不会是框架问题，我把 system 目录 替换为 3.1.7（最新最稳定的codelgniter)的system 目录，果然不报错了！
总结下：出现类似问题，可能原因 是 phpredis扩展 和 redis版本不匹配；框架使用 phpredis 有问题（框架比 phpredis扩展老）；如果是使用predis 还可能它的版本问题。
解决了顺序，先最容易改的，如框架， 再考虑phpredis版本 或predis问题。 最后再考虑redis服务版本。
还要注意 是否有auth !
