dizcuz 不能加载模板问题

今天帮朋友迁移一个教育网站,在目标主机上面搭建好LNMP后,把网站打包上传,数据库备份上传,把数据库导入,网站文件和目录设置好,还有一些乱七八糟的设置设置。配置弄好后,启动程序,测试一下网站是否和原来的功能是否一致,页面是否都正常,需要和没迁移前保持一样。经过测试,其他的几个模块都没有问题,有一个BBS的模块,使用的dizcuz的程序,版本有些老了,打开首页直接显示模板内容了。看了对应的php是可以解析的,php解析没有问题,再看权限,设置的也合理。最后看了看解析的代码页没有问题,网站的文件都是打包过来的,文件一致性肯定能保证,肯定是环境哪里设置的问题。最好找了半天发现一个php的参数没有修改,原来是short_open_tag = Off,修改为On,重启一下php-fpm,(如果你是apache+php模块,就重启apache),再次访问就正常了。关于这个参数区别如下:

php.ini
; This directive determines whether or not PHP will recognize code between
;  tags as PHP source which should be processed as such. It's been
; recommended for several years that you not use the short tag "short cut" and
; instead to use the full  tag combination. With the wide spread use
; of XML and use of these tags by other languages, the server can become easily
; confused and end up parsing the wrong code in the wrong context. But because
; this short cut has been a feature for such a long time, it's currently still
; supported for backwards compatibility, but we recommend you don't use them.
; Default Value: On
; Development Value: Off
; Production Value: Off
; http://php.net/short-open-tag
short_open_tag = On

这种情况也只有迁移的时候会遇到,如果重新安装,discuz检查php参数的时候肯定是报错不通过的。
