設置清漆同一服務器上的Web服務器

Question

公司最近決定開始與清漆HTTP加速器工作。我們爲什麼選擇這個解決方案最重要的是，因爲我們是一家專門從事開發Web商店（Magento企業）公司=> Magento的有清漆一起工作的商業插件。

的清漆配置已經存在於我們的測試環境，其包含運行的清漆例如，2個Apache服務器和1個存儲+ 1個MySQL服務器1（軟件）負載平衡器。

但是現在時機已經到了光油添加到我們的開發環境（VirtualBox的與具有數據庫，網絡服務器，運行的所有在同一臺機器上的文件的RAM運行Debian的1GB）

任何人都可以發表默認.vcl配置文件爲此設置？

的Apache2在端口上運行提前80

感謝， 肯尼

編輯：我發現貼在下面the solution。

Answer 1

後我發現更多的搜索解決方案。基本上我們需要確保清漆在8080端口上聽取80端口和apache（或其他任何東西！）。

這裏我default.vcl文件（位於/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 <errno.h> 
#include <limits.h> 
}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); 
} 

這裏的清漆文件的內容（在/ etc /默認/清漆）：

# Configuration file for varnish 
# 
# /etc/init.d/varnish expects the variables $DAEMON_OPTS, $NFILES and $MEMLOCK 
# to be set from this shell script fragment. 
# 

# Should we start varnishd at boot? Set to "yes" to enable. 
START=yes 

# Maximum number of open files (for ulimit -n) 
NFILES=131072 

# Maximum locked memory size (for ulimit -l) 
# Used for locking the shared memory log in memory. If you increase log size, 
# you need to increase this number as well 
MEMLOCK=82000 

# Default varnish instance name is the local nodename. Can be overridden with 
# the -n switch, to have more instances on a single server. 
INSTANCE=$(uname -n) 

# This file contains 4 alternatives, please use only one. 

## Alternative 1, Minimal configuration, no VCL 
# 
# Listen on port 6081, administration on localhost:6082, and forward to 
# content server on localhost:8080. Use a 1GB fixed-size cache file.

## Alternative 2, Configuration with VCL 
# 
# Listen on port 6081, administration on localhost:6082, and forward to 
# one content server selected by the vcl file, based on the request. Use a 1GB 
# fixed-size cache file.

## Alternative 4, Do It Yourself

Answer 2

這個環節對大製作的網站使用光油的一個很好的討論。特別是，看的/ etc /默認/清漆或/ etc/SYSCONFIG /清漆DAEMON OPTS該放緩存「文件」到內存中，而不是磁盤：

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

的片斷我說約：

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"
