如题，PHP启用SESSION后抛

**Warning**: session\_start(): open(/var/lib/php/session\_user/sess\_d5gn9q7q9qii26ajk2c8ltrefs, O\_RDWR) failed: No such file or directory (2) in **/data/webDev/websites/daza.ren/session-util.php**on line **3**  
  
**Warning**: session\_start(): Failed to read session data: files (path: /var/lib/php/session) in **/data/webDev/websites/daza.ren/session-util.php** on line **3**

以及下面权限方面的错误，

**Warning**: Unknown: open(/usr/local/temp/sess\_ho0i0q5ircrvu1h3i2fa4n3df0, O\_RDWR) failed: Permission denied (13) in **Unknown** on line **0**  
  
**Warning**: Unknown: Failed to read session data: files (path: /usr/local/temp) in **Unknown** on line **0**  
  
**Warning**: session\_start(): open(/usr/local/temp/sess\_ho0i0q5ircrvu1h3i2fa4n3df0, O\_RDWR) failed: Permission denied (13) in **/data/webDev/websites/daza.ren/session-util.php** on line **3**  
  
**Warning**: session\_start(): Failed to read session data: files (path: /usr/local/temp) in **/data/webDev/websites/daza.ren/session-util.php** on line **3**

\----------------------------------------------------------

**解决办法:  修改 php.ini  (whereis php.ini) 查找**

**1. 修改下面的 session.save\_path 为实际设定路径。如下:**

1354 ; where MODE is the octal representation of the mode. Note that this
    1355 ; does not overwrite the process's umask.
    1356 ; http://php.net/session.save-path
    1357 ;session.save_path = "/tmp"
    1358 session.save_path = "/usr/local/php/temp"

**2. 修改下面的 session.gc\_maxlifetim为实际时间。如下:**

1435 ; After this number of seconds, stored data will be seen as 'garbage' and
    1436 ; cleaned up by the garbage collection process.
    1437 ; http://php.net/session.gc-maxlifetime
    1438 session.gc_maxlifetime = 3600

以及

; Initialize session on request startup.
    ; http://php.net/session.auto-start
    ; session.auto_start = 0
    session.auto_start = 1

由于我使用的是 php-fpm,  session.save\_path 在 /etc/php.ini中设置后不生效，

**Warning**: session\_start(): open(/var/lib/php/session\_user/sess\_d5gn9q7q9qii26ajk2c8ltrefs, O\_RDWR) failed: No such file or directory (2) in **/data/webDev/websites/daza.ren/session-util.php**on line **3  
抛错实际生效的地方是 **/usr/local/php/etc/php-fpm.d/www.conf

410 ; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
    411 ; 2018-11-08
    412 php_value[session.save_handler] = files
    413 ; php_value[session.save_path] = /var/lib/php/session
    414 php_value[session.save_path] = /usr/local/temp

**3. 创建 "/usr/local/php/temp" 目录并确保权限**

//查看权限
    ls -ld /usr/local/temp
    
    //以下 user和user-group 请根据实际填写 
    chown -R user:user-group /usr/local/temp && chmod 777 -R /usr/local/temp

**4. 重启 php-fpm 和 nginx**

**php-fpm:**

**\#启动服务     service php-fpm start   
\#停止服务     service php-fpm stop **

**nginx:**

**\#启动服务     nginx -s stop  
\#启动服务     nginx**

--------------------

其它参考:

use `session_save_path()` on page starting

refer : [http://php.net/manual/en/function.session-save-path.php][http_php.net_manual_en_function.session-save-path.php]

I eventually managed to get it working by putting the full path of my new folder in..
