linux安装tomcat后启动报错Cannot find ./catalina.sh的解决方法

linux安装tomcat后启动报错：

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

原因：无权限

解决方法：

1. chmod +x /usr/tomcat7/bin/*.sh  （亲测可用）
 
2. chmod 755 /usr/tomcat7/bin/*.sh
 
3. chmod 777 /usr/tomcat7/bin/*.sh
