varnish 編譯安裝
下載地址：http://varnish-cache.org/releases/
這裏用的是varnish-4.1.11版本
varnish4版本使用python2.6便可，varnish6版本要求python2.7css

命令行啓動：
sudo -u varnish /home/tools/varnish/bin/varnishncsa -F "%{X-Forwarded-For}i %l %u %t \"%r\" %s %b \"%{Referer}i\" \"%{User-agent}i\" %D" -a -w /home/tools/varnish/logs/log.log -D
命令行關閉：
pkill varnishncsa
參數：
-a：當把日誌寫到文件裏時，使用附加方式而不是覆蓋；
-C：作正則表達式和字符匹配時不區分大小寫；
-d：在日誌的首部開始處理日誌記錄而不是日誌結尾；
-D：以守護進程方式運行；
-F format：設置輸出日誌格式字符串；
-g ：日誌記錄的分組，默認分組爲vxid;
-h：打印varnishlog用法並退出；
-n name：指定varnish實例用來獲取日誌的名稱，若是未指定-n參數，那麼就使用主機名；
-N filename：指定過期VSM實例的文件名。當使用這個參數時，放棄檢查功能會被禁用；
-P file：將進程的PID寫入到指定文件中；
-q query：使用指定的VSL；
-V：打印版本信息並退出；
-w filename：重定向輸出到指定文件，若是-a參數未指定那麼該文件將會被覆蓋重寫
-F 指定格式FORMAT：
指定可使用的日誌格式，若是未指定那麼就使用默認的格式；
默認的日誌格式爲：
%h %l %u %t "%r" %s %b "%{Referer}i" "%{User-agent}i"
支持轉義字符\n和\t；
支持的格式標誌符有：
%b：response的字節大小，不包括HTTP報頭。當沒有字節被髮送時，CLF格式中是 - 而不是0；
%D：處理請求的實際時間，單位爲微秒；
%H：請求協議。若是不知道的話默認爲HTTP/1.0；
%h：遠程主機。若是不知道的話默認爲 - ；
%I：從客戶端接收的總字節大小；
%{X}i：請求報頭X的內容；
%l：遠程登陸用戶(老是爲 - );
%m:請求方法；若是不知道的話默認爲 -
%{X}o：響應報頭X的內容；
%O：發送的總字節大小；
%q：查詢字符串，若是沒有查詢字符串存在，使用空字符串；
%r：請求的第一行。從其餘字段合成，因此可能不會原樣呈現請求；
%s：發送到客戶端的狀態；
%t：請求被接受時的時間(HTTP date/time格式);
%{X}t：請求被接受時的時間(以指定的X格式)。時間規範格式和strftime同樣；
%T：處理請求的實際時間，單位爲秒；
%U：不帶有任何查詢字符串的URL請求。若是不知道的話默認爲 - ；
%u：遠程認證用戶；
%{X}x：擴展變量。支持的變量有：
Varnish:time_firstbyte
從請求開始處理到第一個字節被髮送到客戶端的時間
Varnish:hitmiss
請求是否命中緩存。pipe和pass被看做是未命中的；
Varnish:handling
請求是如何處理的，它是緩存命中 未命中 pass pipe仍是error的；
VCL_Log:key
在VCL中由std.log("key:value")設置值；
