修改tomcat/conf目錄裡面server.xml檔案

例如下面這樣新增一個8081埠，設定下appBase目錄，這樣就可以用一個tomcat監聽多個埠，每個埠都可以放應用了。我這樣新增下面這個配置以後，tomcat就監聽了2個埠（8080，8081）

webapps目錄和webapps1目錄的應用都會啟動，可以根據不同的埠進行訪問裡面的應用

OK

把專案war包改名為ROOT放進appBase屬性指定的路徑下啟動服務即可。

附：Tomcat埠說明：

1. 採用記事本開啟Tomcat安裝目錄下的conf資料夾下的server.xml檔案。 
2. 在server.xml檔案中找到以下程式碼： 
（1）<connector port="8080"protocol="HTTP/1.1"connectionTimeout="20000" 
redirectPort="8443"/> 
此聯結器是負責建立HTTP連線。再通過瀏覽器訪問Tomcat伺服器的web應用時使用的就是這個埠，如果此埠被佔用可將其修改一個未被佔用的埠,例如 將上面程式碼中的port="8080"修改為port="8081"，即可將Tomcat的預設埠設定為8081。在修改埠時，應避免與公用埠衝突。建議採用預設的8080埠，不要修改，除非8080埠被其他程式所佔用。 
（2） <Server port="8005" shutdown="SHUTDOWN"> 
8005埠是用來關閉Tomcat服務的埠，如果此埠被佔用,可在配置檔案中將8005改成其他埠 
（3）<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />    
 此聯結器負責和其他的HTTP伺服器建立連線，再把Tomcat與其他的HTTP服務整合時需要使用此聯結器。如果此埠被佔用,可在配置檔案中將8009改成其他埠 
（4）<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" 
maxThreads="150" scheme="https" secure="true" clientAuth="false" 
keystoreFile="D:\Tomcat6.0\conf\tomcat.key" keystorePass="123456" 
sslProtocol="TLS" /> 
此聯結器的作用是啟動HTTPS服務，一般的情況此段內容是被註釋掉的，只有開啟HTTPS服務時才會放開使用，如果此埠被佔用則修改8443埠為其他沒被佔用的埠，並且需要將（1）和（3）中的也要修改 
3.  修改成功後，為了使新設定的埠生效，還需要重新啟動Tomcat伺服器。
