wordpress通过Linux shell脚本自动生成sitemap.xml

<?php
require('./wp-blog-header.php');     //注意：此处为相对路径，根据实际情况填写   
header("Content-type: text/xml");
header('HTTP/1.1 200 OK');
$posts_to_show = 1000; // 获取1000篇文章   
echo '<?xml version="1.0" encoding="UTF-8"?>';
echo '<urlset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">';
?>
<url>
<loc>http://www.cenliming.com/</loc>   
<changefreq>daily</changefreq>
<priority>1.0</priority>
</url>
<?php
header("Content-type: text/xml");
$myposts = get_posts( "numberposts=" . $posts_to_show );
foreach( $myposts as $post ) { ?>
<url>
<loc><?php the_permalink(); ?></loc>
<changefreq>monthly</changefreq>
<priority>0.6</priority>

<?php } // end foreach ?>  
</urlset>
