进入tomcat/bin目录，执行启动的时候出现如下错误：
[root@test bin]# ./startup.sh Cannot find ./catalina.sh The file is absent or does not have execute permission
This file is needed to run this program
解决方法：
在tomcat 的bin目录下 执行这条命令 chmod +x *.sh 再次执行 sh catalina.sh通过，
然后用sh startup.sh启动成功
如下：
[root@test bin]# chmod +x *.sh [root@test bin]# sh catalina.sh
