nginx下搭建CodeIgniter问题集锦
nginx环境下CodeIgniter会出现一些问题!
1、数据库驱动连接失败!
出现如下问题:
A PHP Error was encountered Severity: Warning Message: mysqli::real_connect(): (HY000/2002): No such file or directory Filename: mysqli/mysqli_driver.php
解决方法:
这个问题是php.ini配置的问题。
默认以下配置为空,将以下三个选项设置成你mysql.sock对应的目录就可以解决了。(以下配置为mac下)
mysql.default_socket = /tmp/mysql.sock
pdo_mysql.default_socket= /tmp/mysql.sock
mysqli.default_socket =/tmp/mysql.sock
2、出现Only variable references should be returned by reference报错
A PHP Error was encountered Severity: Notice Message: Only variable references should be returned by reference Filename: core/Common.php Line Number: 257
解决方法:
原代码:
return $_config[0] =& $config;
修改后:
$_config[0] =& $config;
return $_config[0];
3、session报错
A PHP Error was encountered Severity: Warning Message: mkdir(): Invalid path Filename: drivers/Session_files_driver.php Line Number: 117
解决方法:
以ci 3.0为例:
将config配置文件中 将sess_save_path改为如下
$config['sess_save_path'] = FCPATH.'public/sess_save_path';
