I'm on a Centos server and when I tried to run
./script.sh
I get the Permission Denied error even after I tried adding chmod +x script.sh.
sh script.sh works though.
UPDATE
The script file starts with #!/bin/sh
bash shell-script

Could you edit your question to add any error messages output by the failed commands and the first few lines of the script? Also, do you know if the filesystem the script resides on is mounted as noexec or similar?

Most probably your script lacks a "shebang". The system tries to read which interpreting program should be executed to run the script. A "shebang" is recognized by the system if it is on the very first line and starts with #!.
Examples:
#!/bin/bash
#!/bin/sh
#!/usr/bin/env python
#!/bin/sed
Note that #! is a comment otherwise in most scripting languages, so it will not error out if you run it with a specific interpreting program from the command line like so:
$ bash ./script.sh

@Sam, it runs a different shell. Not all systems have Bash, and even on those that do,/bin/shmight not be Bash (e.g. Debian and Ubuntu). See e.g. unix.stackexchange.com/q/250913/170373
