我遇到了redis会话的问题。我将php7，Apache2等安装到我的ubuntu 16.04机器上。我安装了redis服务器，它可以工作。
在php中，当我使用＆＃39;文件＆＃39;作为php会话处理程序，php工作，但当我将php会话处理程序设置为redis并添加代码＆＃39; session_start（）＆＃39;到我的PHP代码，它显示＆＃39;此页面无法使用＆＃39;。为什么呢？
这是我的php.ini文件的一部分
[browscap]
; http://php.net/browscap
;browscap = extra/browscap.ini
[Session]
; Handler used to store/retrieve data.
; http://php.net/session.save-handler
session.save_handler = redis
; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
;
; The path can be defined as:
;
session.save_path = "tcp://127.0.0.1:6379?auth=MYREDISPASS"
;
; where N is an integer. Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories. This is useful if
; your OS has problems with many files in one directory, and is
; a more efficient layout for servers that handle many sessions.
当我执行＆＃39; php index.php＆＃39;在终端，它工作。
