測試了一下tomcat下配置虛擬目錄、多域名、多個(gè)Http監(jiān)聽端口的配置方式，下面做一個(gè)conf/server.xml配置結(jié)果的記錄

該server下面兩個(gè)service節(jié)點(diǎn)，每個(gè)service節(jié)點(diǎn)可以用 Connector 配置一個(gè)監(jiān)聽端口，service里有只能有一個(gè)Engine節(jié)點(diǎn)，它接受同級目錄Connector端口的請求，可以通過defaultHost屬性默認(rèn)指向一個(gè)Host，Host就是一個(gè)該Connector端口下的域名，下面可以用Context配置多個(gè)虛擬目錄。
即：server下面可以有多個(gè)service，用于配置不同監(jiān)聽端口
service下面可以有多個(gè)Host，用于配置該端口下的不同域名
Host里可以包含多個(gè)Context，用于配置該端口該域名下的不同虛擬目錄
上面的配置，可以用下面鏈接訪問：
http://www.test1.com:8088/TestWeb2/
test1,2,3都是我hosts里指向了本地的。
Host下的Alias是一個(gè)域名別稱，可以配置多個(gè)域名。
Host里如果沒有Context節(jié)點(diǎn)，則非webapps文件夾下，直接不用虛擬目錄訪問，會拋404找不到文件的錯誤，比如上面配置中test1域名下必須用虛擬目錄比如這里的TestWeb2來訪問
Host下面的context節(jié)點(diǎn)配置為：<Context path="" 后，則這個(gè)目錄為默認(rèn)的訪問目錄，比如 http://www.test2.com:880/ ，訪問的 D:\TomCat7.0\testapp\TestWebliu 下面的文件。
這里因?yàn)槲矣心J(rèn)首頁，因此直接輸入域名和端口可以直接訪問到默認(rèn)的index.jsp頁面，如果沒有默認(rèn)頁，可能會拋錯，需要配置可以/為列目錄，在conf/web.xml里
<init-param>
??????????? <param-name>listings</param-name>
??????????? <param-value>true</param-value>
??????? </init-param>
把這個(gè)的param-value改為true即為可以列目錄了。
當(dāng)然，如果不配置server.xml文件，直接把網(wǎng)站放到webapps，默認(rèn)會自動加載該網(wǎng)站，因此大多數(shù)情況，我們都不用對server.xml文件做任何修改。
