varnish3安装及配置

1.varnish安装 下载varnish软件  （此处下载3.0.2版本）   #wget http://repo.varnish-cache.org/source/varnish-3.0.2.tar.gz #tar -xvf varnish-3.0.2.tar.gz #cd varnish-3.0.2 #./configure --prefix=/usr/local/varnish #make &&make install 至此安装完成。 注：如果你在编译的vasnish中的bin目录没有发现varnishstat, varnishtop, varnishhist这个三个程序的话，是因为编译前没有安装与操作系统位数对应的ncurses-devel。 安装ncurses-devel  yum install ncurses-devel.x86_64   然后再次编译varnish 即可。   2.varnish配置 #vim /usr/local/varnish/etc/varnish/vcl.conf 以下为配置代码：(除backend 及vcl_recv外，其他地方无需更改，这里是更改其访问的主机名，及定义后端服务器地址，字数有限，其他代码这里就不解释了)      #backend vhost backend 192.168.40.85 { .host = "192.168.40.85"; .port = "80"; } #acl acl purge { "localhost"; "127.0.0.1"; "192.168.0.0"/24; } sub vcl_recv { if (req.http.Accept-Encoding) { if (req.url ~ "\.(jpg|png|gif|jpeg|flv)$" ) { remove req.http.Accept-Encoding; remove req.http.Cookie; } else if (req.http.Accept-Encoding ~ "gzip") { set req.http.Accept-Encoding = "gzip"; } else if (req.http.Accept-Encoding ~ "deflate") { set req.http.Accept-Encoding = "deflate"; } else { remove req.http.Accept-Encoding; } } if (req.http.host ~ "(.*)youdomain.com") { set req.backend = 192.168.40.85; } else { error 404 "This website is maintaining or not exist！"; } if (req.request == "PURGE") { if (!client.ip ~purge) { error 405 "Not Allowed"; } #.dd..... return(lookup); } #...GET...url...jpg,png,gif. ..cookie if (req.request == "GET"&& req.url ~ "\.(png|gif|jpeg|jpg|ico|swf|css|js|html|htm|gz|tgz|bz2|tbz|mp3|ogg|mp4|flv|f4v|pdf)$") { unset req.http.cookie; } #..GET...url.php....cache.... if (req.request =="GET"&&req.url ~ "\.php($|\?)"){ return (pass); } # if (req.restarts == 0) { if (req.http.x-forwarded-for) { set req.http.X-Forwarded-For = req.http.X-Forwarded-For + ", " + client.ip; } else { set req.http.X-Forwarded-For = client.ip; } # } #........pipe.. if (req.request != "GET" && req.request != "HEAD" && req.request != "PUT" && req.request != "POST" && req.request != "TRACE" && req.request != "OPTIONS" && req.request != "DELETE") { return (pipe); } #..GET .HEAD..... if (req.request != "GET" && req.request != "HEAD") { return (pass); } if (req.http.Authorization) { return (pass); } return (lookup); } #..url+host hash...... sub vcl_hash { hash_data(req.url); if (req.http.host) { hash_data(req.http.host); } else { hash_data(server.ip); } return (hash); } # .....purge ..... sub vcl_hit { if (req.request == "PURGE") { set obj.ttl = 0s; error 200 "Purged"; } return (deliver); } sub vcl_fetch { if (req.url ~ "\.(jpeg|jpg|png|gif|gz|tgz|bz2|tbz|mp3|ogg|ico|swf|flv|dmg|js|css|html|htm)$") { set beresp.ttl = 2d; set beresp.http.expires = beresp.ttl; set beresp.http.Cache-Control = "max-age=172800"; unset beresp.http.set-cookie; } if (req.url ~ "\.(dmg|js|css|html|htm)$") { set beresp.do_gzip = true; } if (beresp.status == 503) { set beresp.saintmode = 15s; } } sub vcl_deliver { set resp.http.x-hits = obj.hits ; if (obj.hits > 0) { set resp.http.X-Cache = "HIT You!"; } else { set resp.http.X-Cache = "MISS Me!"; } } 配置文件保存退出 ,并启动 varnish /usr/local/varnish3/sbin/varnishd -f /usr/local/varnish3/etc/varnish/default.vcl -a 192.168.40.84:8080 -u www -g www -p thread_pool_max=51200 - p thread_pools=4 -h classic,500009 -p lru_interval=20 -s file,/a8root/varnish/varnish_cache.data,512M -w 1000,51200,10 -T 192.168，40.84:3500
