  8 #        1.若是tomcat實例是在同一個目錄下，那麼只須要修改此腳本中 "export CATALINA_BASE=(path)/$instance_name" 
  9 #          中的path爲你全部實例的父目錄便可,--instance= 選項就可使用相對路徑
 10 #       2.若是tomcat實例不在同一個目錄下，那麼只須要修改此腳本中 "export CATALINA_BASE=$instance_name"
 11 #          --instance= 選項後面就得跟實例的絕對路徑
 12 #       3.把此腳本放到/usr/local/bin/ 並重名命爲tomcat-multi,注意修改其餘用戶有執行權限

實例操做：

　1.查看一個實例的狀態html

2.查看幫助信息，沒有使用-h選項，不過你能夠故意給錯選項來查看，提供了比較簡單地幾個選項。java

3.多實例操做，須要如下的腳本，你能夠把它保存並重名命爲tomcatd，而後把它扔到/etc/init.d/tomcatd ,確保其有執行權限。數組
