17、在用戶模式下運(yùn)行的發(fā)布Web內(nèi)容的應(yīng)用程序，或者在Inetinfo進(jìn)程之內(nèi)以System帳戶運(yùn)行，或者在Inetinfo進(jìn)程之外以IWAM用戶運(yùn)行。雖然在較重的負(fù)載下，IIS 5.0也有相當(dāng)出色的表現(xiàn)；不過(guò)從IIS 6.0開(kāi)始，我們對(duì)IIS底層結(jié)構(gòu)的看法應(yīng)該改變了。為了使IIS不僅能夠輕松地支持1000個(gè)Web網(wǎng)站，而且能夠支持10000個(gè)甚至更多的網(wǎng)站，同時(shí)還要提高Web服務(wù)器的安全性和可靠性，微軟放棄了原有的IIS內(nèi)核，重新構(gòu)造了一

18、個(gè)。</p><p>　　另一個(gè)促使微軟重新構(gòu)建IIS內(nèi)核的原因是，微軟（以及其他廠商）認(rèn)識(shí)到，Web服務(wù)器的性能和可靠性問(wèn)題絕大部分是由于質(zhì)量低劣的Web應(yīng)用造成。IIS 5.0通過(guò)帶緩沖池的Out of Process容器減輕這類問(wèn)題。在IIS 5.0中，在Out of Process池中運(yùn)行的應(yīng)用一旦崩潰，一般不會(huì)波及到IIS本身，因?yàn)閼?yīng)用程序在Inetinfo之外的進(jìn)程中運(yùn)行，但運(yùn)行在Out of Pro

19、cess池之內(nèi)的所有Web應(yīng)用都會(huì)終止——在默認(rèn)情況下，所有的應(yīng)用程序都在該池之中運(yùn)行。在這種情況下，排解故障很不容易，因?yàn)橐_定哪一個(gè)應(yīng)用程序?qū)е铝藛?wèn)題非常困難。IIS 6.0將監(jiān)聽(tīng)請(qǐng)求、創(chuàng)建和監(jiān)視Web網(wǎng)站、運(yùn)行Web服務(wù)這些不同的任務(wù)隔離了開(kāi)來(lái)，這一新型體系可望解決IIS 5.0存在的問(wèn)題。從理論上看，新的體系將極大地改善可用性、安全和性能；從實(shí)際情況看，根據(jù)微軟和Beta測(cè)試者的報(bào)告，新的體系令穩(wěn)定性和性能有了奇跡般地提高。II

20、S 6.0的內(nèi)核體系主要建立在三個(gè)組件之上：W3SVC，http.sys，以及W3Core。</p><p><b>　　■ W3SVC</b></p><p>　　W3SVC也許是IIS 6.0體系中最不令人注意的組件，不過(guò)這并不說(shuō)明它不重要。W3SVC的任務(wù)是根據(jù)配置數(shù)據(jù)的設(shè)置創(chuàng)建和監(jiān)視工作線程，由工作線程運(yùn)行Web網(wǎng)站應(yīng)用。在IIS 5.0中，與IIS 6.0

21、W3SVC組件最接近的是IIS管理服務(wù)，IIS管理服務(wù)是Inetinfo的一部分；</p><p>　　因此，如果Inetinfo出現(xiàn)問(wèn)題，IIS管理服務(wù)也會(huì)出現(xiàn)問(wèn)題，而且此時(shí)的IIS管理服務(wù)不能再重新啟動(dòng)Inetinfo或其他故障的應(yīng)用程序。在IIS 6.0中，W3SVC作為一個(gè)獨(dú)立的進(jìn)程運(yùn)行，Web應(yīng)用的故障不可能波及W3SVC，因?yàn)閃3SVC之內(nèi)根本沒(méi)有第三方的代碼運(yùn)行。W3SVC總是處于運(yùn)行狀態(tài)，因此它能

22、夠監(jiān)視Web應(yīng)用的健康狀況，并在必要時(shí)采取行動(dòng)。由于這一策略，服務(wù)器能夠根據(jù)用戶指定的參數(shù)監(jiān)視和重新啟動(dòng)應(yīng)用程序。</p><p>　　■ http.sys </p><p>　　IIS 6.0體系設(shè)計(jì)中最重大的變化是加入了http.sys驅(qū)動(dòng)程序，http.sys驅(qū)動(dòng)程序的任務(wù)是處理HTTP請(qǐng)求，而且它在內(nèi)核模式下執(zhí)行操作。不要小看這一改變，將處理HTTP請(qǐng)求的任務(wù)從IIS 5.0、II

23、S 4.0的用戶模式改變到IIS 6.0的內(nèi)核模式標(biāo)志著亂淮鶬IS服務(wù)器的誕生。</p><p>　　在Win 2K和NT 4.0中，IIS在用戶模式下運(yùn)行。運(yùn)行在用戶模式下的應(yīng)用程序不直接與硬件通信，它們直接調(diào)用的是一些標(biāo)準(zhǔn)過(guò)程，這些標(biāo)準(zhǔn)過(guò)程或者將數(shù)據(jù)傳入內(nèi)核模式的組件（例如網(wǎng)卡驅(qū)動(dòng)程序，圖形子系統(tǒng)），或者調(diào)用內(nèi)核模式組件的函數(shù)，以此完成保存文件、設(shè)置IP地址、將HTML文件發(fā)送到網(wǎng)絡(luò)之類的任務(wù)。 </p

24、><p>　　用戶模式和內(nèi)核模式之間的轉(zhuǎn)換是一項(xiàng)開(kāi)銷很大的操作，服務(wù)器首先從內(nèi)核模式的TCP/IP棧將傳入的HTTP請(qǐng)求傳遞給用戶模式的Winsock，由Winsock將請(qǐng)求傳遞給IIS。從內(nèi)核模式到用戶模式的切換很快發(fā)生，但不可避免地給處理過(guò)程帶來(lái)瞬間的延遲。當(dāng)負(fù)載較大時(shí)，這種延遲不斷累加，同時(shí)由于這種轉(zhuǎn)換是必不可少的，所以管理員根本沒(méi)有辦法優(yōu)化處理過(guò)程。</p><p><b>

25、　　四、應(yīng)用程序池詳解</b></p><p>　　下面來(lái)看看有關(guān)應(yīng)用程序池的一些問(wèn)題。應(yīng)用程序池的“屬性”對(duì)話框有四頁(yè)——回收，性能，運(yùn)行狀況，標(biāo)識(shí)。在這些選項(xiàng)頁(yè)中，最引人注目的恐怕就是“回收”頁(yè)，使用該選項(xiàng)頁(yè)可以管理工作進(jìn)程的回收。在工作進(jìn)程隔離模式中， IIS可以配置成定期重新啟動(dòng)應(yīng)用程序池中的工作進(jìn)程，從而更好地管理那些有錯(cuò)誤的工作進(jìn)程。這確保了池中的應(yīng)用程序運(yùn)行正常，并且可以恢復(fù)丟失的系統(tǒng)資

26、源。為了回收工作進(jìn)程，失敗工作進(jìn)程接收請(qǐng)求的能力將被限制，直到它處理完存儲(chǔ)在請(qǐng)求隊(duì)列中的所有剩余請(qǐng)求。為了排出當(dāng)前請(qǐng)求，可以給予進(jìn)程配置限制。同一命名空間組的替換工作進(jìn)程在舊的工作進(jìn)程停止前啟動(dòng)，從而防止服務(wù)中斷。舊的進(jìn)程完成其未決的請(qǐng)求，然后正常關(guān)閉，或者如果在達(dá)到了配置的時(shí)間限制、請(qǐng)求數(shù)、設(shè)置的時(shí)間計(jì)劃，或當(dāng)達(dá)到指定的內(nèi)存用量限制后仍沒(méi)有關(guān)閉，則明確地終止進(jìn)程。默認(rèn)情況下，應(yīng)用程序池每隔1740分鐘（29小時(shí)）回收一次。</p

27、><p>　　W3SVC根據(jù)“運(yùn)行狀況”頁(yè)的選項(xiàng)來(lái)判斷應(yīng)用程序池運(yùn)行是否正常，包括：每隔指定的時(shí)間Ping工作進(jìn)程，時(shí)間按秒計(jì)，默認(rèn)值30秒；啟動(dòng)時(shí)間限制（工作進(jìn)程必須在指定的時(shí)間內(nèi)開(kāi)始）；關(guān)閉時(shí)間限制（工作進(jìn)程必須在指定的時(shí)間內(nèi)關(guān)閉）；是否啟動(dòng)快速失敗保護(hù)（如果在指定的時(shí)間段內(nèi)一定數(shù)目的工作進(jìn)程發(fā)生失敗，則禁用應(yīng)用程序池）。另外，ISAPI應(yīng)用程序（包括ASP.NET和asp.dll）可以聲明自己不再適合提供服務(wù)，

28、要求回收。</p><p>　　默認(rèn)情況下，當(dāng)IIS 6.0回收一個(gè)池時(shí)，它會(huì)使用一種稱為overlapped recycle的回收技術(shù)。在這種回收模式下，失敗的工作進(jìn)程仍會(huì)保持運(yùn)行狀態(tài)，同時(shí)創(chuàng)建一個(gè)新的工作進(jìn)程。IIS 6.0把新傳入的請(qǐng)求傳遞給新的工作進(jìn)程，但不拆除老的工作進(jìn)程，直至老的工作進(jìn)程處理完它隊(duì)列中的請(qǐng)求，或者遇到超時(shí)錯(cuò)誤。在此期間，TCP/IP連接不會(huì)丟失，因?yàn)橛衕ttp.sys保持著連接的有效性

29、。當(dāng)失敗的工作進(jìn)程超時(shí)出錯(cuò)時(shí)，下一個(gè)請(qǐng)求傳遞給工作進(jìn)程的請(qǐng)求是新的請(qǐng)求，因此原來(lái)保存在進(jìn)程中的會(huì)話信息就會(huì)丟失。所有這類回收操作都自動(dòng)進(jìn)行，無(wú)需管理員干預(yù)，而且在大多數(shù)情況下，不會(huì)造成明顯的服務(wù)中斷現(xiàn)象。如有必要，可以將配置數(shù)據(jù)屬性LogEventOnRecycle的值設(shè)置為1，指示W(wǎng)3SVC執(zhí)行回收操作時(shí)生成一條事件日志記錄。</p><p>　　對(duì)于那些不能以多個(gè)實(shí)例運(yùn)行的應(yīng)用程序，overlapped re

30、cycle回收技術(shù)可能引起問(wèn)題。如果遇到這類問(wèn)題，可以將配置數(shù)據(jù)屬性DissallowOverlappingRotation的值設(shè)置成True（1），關(guān)閉某個(gè)應(yīng)用程序池回收操作時(shí)的進(jìn)程“重疊”現(xiàn)象。另外，對(duì)于失敗的工作進(jìn)程，有時(shí)我們可能不想將它拆除，仍舊保留該進(jìn)程，以便檢測(cè)和尋找發(fā)生問(wèn)題的根源，這時(shí)可以將配置數(shù)據(jù)屬性O(shè)rphanActionExe設(shè)置成執(zhí)行文件的名字，使得工作進(jìn)程成為“孤兒”時(shí)執(zhí)行文件仍保持運(yùn)行狀態(tài)。</p>

31、<p>　　另一個(gè)與應(yīng)用程序池有關(guān)的特性是，IIS 6.0允許將應(yīng)用程序池配置成一個(gè)Web園（Web Garden）。要理解Web園的概念，可以設(shè)想這樣一種情形：假設(shè)有一個(gè)IIS 5.0服務(wù)器和三個(gè)Web網(wǎng)站，每一個(gè)Web網(wǎng)站運(yùn)行著相同的應(yīng)用程序，如果IIS 5.0能夠自動(dòng)按照?qǐng)A形循環(huán)的模式將請(qǐng)求依次發(fā)送給這些功能上等價(jià)、實(shí)際上分離的Web網(wǎng)站，將負(fù)載分離到三個(gè)不同的進(jìn)程，就可以構(gòu)成一個(gè)小型的Web農(nóng)場(chǎng)（Web Farm）
