        .sh文件都不是可執行文件，于是找到命令：
        
          
            chmod +x *.sh
          
        
        ，這個命令的意思是讓所有的.sh文件都可執行。再次執行sh catalina.sh通過，然后用sh startup.sh成功啟動。






        
          :w 保存文件但不退出vi :w file 將修改另外保存到file中，不退出vi :w! 強制保存，不推出vi :wq 保存文件并退出vi :wq! 強制保存文件，并退出vi q：不保存文件，退出vi :q!不保存文件，強制退出vi :e! 放棄所有修改，從上次保存文件開始再編輯
