小知识：varnish 配置文件分享(sens杨注释)

前言：

varnish 为目前新兴起来的软件，由于中文文档比较少，配置文件比较复杂，所以在运用起来也是特别的费劲。一个偶然的机会在一个群里，有位varnish高手（ sens杨）发表了一篇他对varnish配置文件理解的文档。对于学者来说很有价值。所以转载了过来。

原文如下：

绿色部分是一些思考，这个配置对自身的业务配置的很详细，现在对除了cookie和TTL那部分外其他可以理解80%，慢慢学习体会 backend default { .host = “127.0.0.1”; .port = “8008”; .connect_timeout = 600s; .first_byte_timeout = 600s; .between_bytes_timeout = 600s; } backend lighttpd { .host = “127.0.0.1”; .port = “81”; .connect_timeout = 600s; .first_byte_timeout = 600s; .between_bytes_timeout = 600s; } acl techmission_internal { “localhost”; “127.0.0.1”; } sub vcl_recv { // Allow a grace period for offering “stale” data incase backend lags (http://varnish-cache.org/wiki/VCLExampleGrace) // 如果backend数据滞后，允许为“过时”数据提供一个宽松期 set req.grace = 5m; // block outside world from our test sites // 阻止非自己说测试网站（的数据访问） if ((req.http.host ~ “www.domain1.org|www.domain2.org”) && !(client.ip ~ techmission_internal) && !(req.url ~ “^/ad|^/files”)) { error 403 “Forbidden”; } if((req.url ~ “/server-status” || req.url ~ “/whm-server-status”) && !(client.ip ~ techmission_internal)) { error 404 “Not Found”; } // add ping url to test Varnish status // 增加ping URL测试varnish状态（这个功能使用大部分vcl都没配置，可以增加一个监控状态） if (req.request == “GET” && req.url ~ “/varnish-ping”) { error 200 “OK”; } /* Normalize host header to reduce variation in cache */ // 使host头规范化，以减少在cache中变化（这个为什么会说变化呢？） if (req.http.host == “domain.org” && req.url !~ “^/blogs”) { set req.http.host = “www.domain.org”; } /* Normalize Accept-Encoding to reduce effects of Vary: Accept-Encoding (cf. http://varnish-cache.org/wiki/FAQ/Compression) Also note that Vary: User-Agent is considered harmful (cf. http://www.mail-archive.com/varnish-misc@projects.linpro.no/msg03296.html) */ //规范化Accept-Encoding以减少Vary：Accept-Encoding影响（cf），也要注意Vary: User-Agent认为是有害的 if (req.http.Accept-Encoding) { //if先判断是否可以存在，是为了缩小处理范围？ //看到的其他大部分配置直接就下面了，没有先判断Accept-Encoding是否存在，这点可以再考虑考虑 //现在有req.can_gzip参数了，判断客户端是否接受压缩代码传输 if (req.url ~ “\.(jpg|png|gif|gz|tgz|bz2|tbz|mp3|ogg)$”) { // Dont compress already-compressed files remove req.http.Accept-Encoding; } elsif (req.http.Accept-Encoding ~ “gzip”) { set req.http.Accept-Encoding = “gzip”; } elsif (req.http.Accept-Encoding ~ “deflate”) { set req.http.Accept-Encoding = “deflate”; } else { // unknown algorithm // 不了解运算 remove req.http.Accept-Encoding; } } // Remove has_js and Google Analytics __* cookies.
