sub vcl_fini {
return (ok);
}
四、启动
启动命令
/usr/local/varnish3.0/sbin/varnishd -f /usr/local/varnish3.0/etc/varnish/default.vcl -s malloc,2G -a 0.0.0.0:80 -w 1024,51200,10 -t
3600 -T 192.168.100.2:3500
检测配置文件是否存在错误
/usr/local/varnish3.0/sbin/varnishd －C -f /usr/local/varnish3.0/etc/varnish/default.vcl
参数
－a address:port 监听端口
－f 指定配置文件
－s 指定缓存类型 malloc为内存， file 文件缓存
－t 默认TTL
－T address:port 管理端口
－w 最小线程，最大线程，超时时间
记录varnish日志
/usr/local/varnish3.0/bin/varnishncsa -w /var/logs/varnish.log &
五、缓存刷新
php脚步如下
<?php
function purge($ip, $url)
{
$errstr = '';
$errno = '';
$fp = fsockopen ($ip, 80, $errno, $errstr, 2);
if (!$fp)
{
return false;
}
else
{
$out = "PURGE $url HTTP/1.1\r\n";
$out .= "Host:image.android.com\r\n";
$out .= "Connection: close\r\n\r\n";
fputs ($fp, $out);
$out = fgets($fp , 4096);
fclose ($fp);
return true;
}
}
if(isset($_POST['content'])) {
//$str=str_replace("\r","<br>",$_POST[content]);
$arr=(explode("\n",$_POST['content']));
$Server="192.168.100.2";
foreach ($arr as $value)
{
echo $value;
purge($Server, $value);
echo "刷新成功"."<br />";
}
//purge($Server, "$_POST[content]");
//echo "刷新成功";
}
?>
