Mac system startup startup.sh tomcat startup failure problem!

https://blog.csdn.net/juniorkang/article/details/52872683

Execute chmod +x *.sh directly in the bin directory to add executable permissions to all script files

Then use the command sh startup.sh to start Tomcat

when starting 

juniorkangdeMacBook-Pro:bin juniorkang$ ./startup.sh

-bash: ./startup.sh: Permission denied

Prompt no permission  

Then changing the permissions to 777 doesn't work

juniorkangdeMacBook-Pro:bin juniorkang$ chmod 777 startup.sh 

Still prompt not as follows!

juniorkangdeMacBook-Pro:bin juniorkang$ ./startup.sh 

Cannot find ./catalina.sh

The file is absent or does not have execute permission

This file is needed to run this program

When prompted for this!

only use

juniorkangdeMacBook-Pro:bin juniorkang$ chmod +x *.sh 

Then it works!

juniorkangdeMacBook-Pro:bin juniorkang$ sh startup.sh
