在与Web服务器相同的服务器上设置清漆

我们公司最近决定开始使用Varnish HTTP加速器.最重要的是我们选择这个解决方案的原因是因为我们是一家专门建立网店的公司(Magento Enterprise)=> Magento有一个商业插件,与清漆一起使用.

清漆配置已经存在于我们的测试环境中,其中包含运行清漆实例的1(软件)负载均衡器,2个apache webservers和1个​​存储+ 1个mysql服务器.

然而,现在是时候将Varnish添加到我们的开发环境中(虚拟机具有1GB的ram运行debian,其中包含数据库,webserver,文件在同一台机器上运行)

任何人都可以为此设置发布default.vcl配置文件吗？

Apache2在端口80上运行.

提前谢谢,肯尼

编辑:我发现并发布了以下解决方案.

此链接对在大型生产网站上使用Varnish进行了很好的讨论.特别是,查看将缓存"文件"放入内存而不是磁盘的/ etc/default/varnish或/ etc/sysconfig/varnish DAEMON OPTS:

http://www.lullabot.com/articles/varnish-multiple-web-servers-drupal

我正在谈论的片段:

DAEMON_OPTS="-a :80,:443 \
             -T localhost:6082 \
             -f /etc/varnish/default.vcl \
             -u varnish -g varnish \
             -S /etc/varnish/secret \
             -p thread_pool_add_delay=2 \
             -p thread_pools=2 \
             -p thread_pool_min=400 \
             -p thread_pool_max=4000 \
             -p session_linger=50 \
             -p sess_workspace=262144 \
             -s malloc,3G"

经过多次搜索,我找到了解决方案.基本上我们需要确保清漆正在监听8080端口上的80端口和apache(或其他任何东西!).

这是我的default.vcl文件(位于/etc/varnish/default.vcl):

# default backend definition.  Set this to point to your content server.
backend apache1 {
  .host = "127.0.0.1";
  .port = "8080";
}

director lb round-robin {
    {.backend=apache1;}
}

# add your Magento server IP to allow purges from the backend
acl purge {
  "localhost";
  "127.0.0.1";
}

# needed for TTL handling
C{
#include 
#include 
}C


sub vcl_recv {

    set req.backend=lb;

    if (req.request != "GET" &&
      req.request != "HEAD" &&
      req.request != "PUT" &&
      req.request != "POST" &&
      req.request != "TRACE" &&
      req.request != "OPTIONS" &&
      req.request != "DELETE" &&
      req.request != "PURGE") {
        /* Non-RFC2616 or CONNECT which is weird. */
        return (pipe);
    }

    # purge request
    if (req.request == "PURGE") {
        if (!client.ip ~ purge) {
            error 405 "Not allowed.";
        }
        purge("obj.http.X-Purge-Host ~ " req.http.X-Purge-Host " && obj.http.X-Purge-URL ~ " req.http.X-Purge-Regex " && obj.http.Content-Type ~ " req.http.X-Purge-Content-Type);
        error 200 "Purged.";
    }

    # we only deal with GET and HEAD by default    
    if (req.request != "GET" && req.request != "HEAD") {
        return (pass);
    }

    # static files are always cacheable. remove SSL flag and cookie
    if (req.url ~ "^/(media|js|skin)/.*\.(png|jpg|jpeg|gif|css|js|swf|ico)$") {
        unset req.http.Https;
        unset req.http.Cookie;
    }

    # not cacheable by default
    if (req.http.Authorization || req.http.Https) {
        return (pass);
    }

    # do not cache any page from
    # - index files
    # - ...
    if (req.url ~ "^/(index)") {
        return (pass);
    }

    # as soon as we have a NO_CACHE or admin cookie pass request
    if (req.http.cookie ~ "(NO_CACHE|adminhtml)=") {
        return (pass);
    }

    # normalize Aceept-Encoding header
    # http://varnish.projects.linpro.no/wiki/FAQ/Compression
    if (req.http.Accept-Encoding) {
        if (req.url ~ "\.(jpg|png|gif|gz|tgz|bz2|tbz|mp3|ogg|swf|flv)$") {
            # No point in compressing these
            remove req.http.Accept-Encoding;
        } elsif (req.http.Accept-Encoding ~ "gzip") {
            set req.http.Accept-Encoding = "gzip";
        } elsif (req.http.Accept-Encoding ~ "deflate" && req.http.user-agent !~ "MSIE") {
            set req.http.Accept-Encoding = "deflate";
        } else {
            # unkown algorithm
            remove req.http.Accept-Encoding;
        }
    }

    # remove Google gclid parameters
    set req.url = regsuball(req.url,"\?gclid=[^&]+$",""); # strips when QS = "?gclid=AAA"
    set req.url = regsuball(req.url,"\?gclid=[^&]+&","?"); # strips when QS = "?gclid=AAA&foo=bar"
    set req.url = regsuball(req.url,"&gclid=[^&]+",""); # strips when QS = "?foo=bar&gclid=AAA" or QS = "?foo=bar&gclid=AAA&bar=baz"

    # decided to cache. remove cookie
    #unset req.http.Cookie;

    return (lookup);
}

这是清漆文件的内容(/ etc/default/varnish):

# Configuration file for varnish

START=yes

# Maximum number of open files (for ulimit -n)
