排查：

1：打开apache的错误日志apache_error.log，如果出现Invalid command 'RewriteEngine', 那说明apache没有开启rewrite模式

解决：

1：打开Apache安装目录下httpd.conf，搜索“LoadModule rewrite_modulemodules/mod_rewrite.so”，找到这一行，去掉前面的“#”；
2：找到“AllowOverride None”改为“AllowOverride All” 有两个地方需要修改
3：新建.haccess文件,放在当前网站根目录下，在.haccess文件中写伪静态规则，比如：

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
</IfModule>
 

4：重启apache
