CodeIgniter与nginx搭配
CodeIgniter与nginx配合时，经常会遇到这两个错误提示：
File not found No input file specified
这个错误跟path_info有关，需要在nginx中对应的站点配置中做简单配置。下面我把我的一个站点配置贴出来供参考：
server { listen 80; server_name services.xx.com; server_name_in_redirect off; root /data/web/xx/services; index index.php index.htm index.html; error_log /data/log/xx/web_common/error.log ; access_log /data/log/xx/web_common/access.log main; location / { index index.php index.html; } if (!-e $request_filename) { rewrite ^/(.*)$ /index.php/$1 last; break; } location ~ .*\.(svn|git|cvs) { deny all; } location ~* \.(htm|html|xml|shtml)$ { expires 600; } location ~* \.(js|css|htc|gif|ico|png|swf|jpg|jpeg|bmp)$ { expires 365d; } location ~* \.(bak|tar|gz|zip|tgz|sql)$ { return 403; } location ~ .*.php($|/) { fastcgi_split_path_info ^(.+\.php)(.*)$; fastcgi_param PATH_INFO $fastcgi_path_info; include php_fastcgi_params; fastcgi_pass unix:/tmp/php-fpm.sock; fastcgi_index index.php; } }特别注意最后一个配置中的 fastcgi_split_path_info和 fastcgi_param PATH_INFO以及 location ~ .*.php($|/)。仔细对比自己的配置和我的配置吧。
对于有子站点的情况，比如我的CI目录结构是这样的：
---- application |---- api |---- wechat---- system---- logs……
application目录下放各个子站点，并通过同一个二级域名访问，假设是 apps.xx.com，那么各个子站点的访问链接为：
http://apps.xx.com/apihttp://apps.xx.com/wechat
那么，apps这个二级域名对应的配置为：
server { listen 80; server_name apps.xx.com; server_name_in_redirect off; root /data/web/xx/application; index index.php index.htm index.html; error_log /data/log/xx/web_common/error.log ; access_log /data/log/xx/web_common/access.log main; location / { index index.php index.html; } location /api { index index.php index.html; if ( !-e $request_filename ) { rewrite ^/api/(.+)$ /api/index.php/$1 last; break; } } location /wechat { index index.php index.html; if ( !-e $request_filename ) { rewrite ^/wechat/(.+)$ /wechat/index.php/$1 last; break; } } location ~ .*\.(svn|git|cvs) { deny all; } location ~* \.(htm|html|xml|shtml)$ { expires 600; } location ~* \.(js|css|htc|gif|ico|png|swf|jpg|jpeg|bmp)$ { expires 365d; } location ~* \.(bak|tar|gz|zip|tgz|sql)$ { return 403; } location ~ .*.php($|/) { fastcgi_split_path_info ^(.+\.php)(.*)$; fastcgi_param PATH_INFO $fastcgi_path_info; include php_fastcgi_params; fastcgi_pass unix:/tmp/php-fpm.sock; fastcgi_index index.php; } }注意各个子站点的配置。
