Cannot find ./catalina.sh The file is absent or does not have execute permission This file is needed

在Linux上启动Tomcat报错并提示：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：
1.查看tomcat的bin目录下的执行权限，如果权限不够，执行以下命令：

chmod +x *.sh

2.再次执行

./startup.sh

执行成功如图：
