如果是用lnmp脚本一键安装的开发环境，可以通过如下方式开户pathinfo：
1、注释nginx.conf中的try_files（因为跟pathinfo.conf中的重复了），开启pathinfo.conf配置：
<span>1</span> location ~ [^/]\.php(/|<span>$)
</span><span>2</span> <span>{
</span><span>3</span> # comment try_files $uri =<span>404</span><span>; to enable pathinfo
</span><span>4</span> #try_files $uri =<span>404</span><span>;
</span><span>5</span> fastcgi_pass unix:/tmp/php-<span>cgi.sock;
</span><span>6</span> <span> fastcgi_index index.php;
</span><span>7</span> <span> include fastcgi.conf;
</span><span>8</span> <span> include pathinfo.conf;
</span><span>9</span> }即注释掉第4行，打开第8行。
2、重启nginx服务：
nginx -s reload
