linux下执行命令报错Cannot find ./catalina.sh The file is absent or does not have execute permission

启动linux上的tomcat时
进入tomcat/bin目录，执行启动的时候出现如下错误：

[[email protected] 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

原因：文件没有权限
解决方法：给bin文件夹赋权

在tomcat 的bin目录下 执行这条命令

[[email protected] bin]# chmod +x *.sh  

再执行 sh catalina.sh就可以啦，

然后用sh startup.sh启动成功
