PHP启用session后抛 session_start(): open(/var/lib/php/session/sess_... 的解决办法

使用mac，php开发环境比较特殊,遇到了session 存储读取的问题

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.phpon 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
• 2. 修改下面的 session.gc_maxlifetim为实际时间

备注

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.phpon line 3
抛错实际生效的地方是 /usr/local/php/etc/php-fpm.d/www.conf
