comment How to list groups with gid in redhat?
@kinkajou lots of professional experience as well as a lot of time spent on sites such as this one and IRC Linux support. I have been a professional and an enthusiast for about 8 years. I think being an enthusiast is an important part because you are more likely to remember things that you care about.

@Braiam then you have failed to assign your server an actual hostname. Using what you assigned may still work however.

Is there really a big problem with the ntp packages that CentOS provides? You are missing openssl development libraries.

comment How do I prevent crashing my ec2 micro instance mysql db?
You need to fix your mysql configuration. You have it configured to use more memory than your system has. mysqltuner can help you determine the correct values.

comment How to store a variable that increments by the index?
ifconfig is deprecated, but it's unlikely to ever go away. The assumption that interfaces are always sequentially numbered is bad. That isn't your problem though as this answers OP's question.

The problem is that your program is exiting with exit code 1. What happens when you run it outside of systemd?

comment Whatis command (shell builtin vs executable programs)
@schily I removed the command example. What do you mean type does not implement options? POSIX doesn't require it to support options, but it does in bash, and zsh. It exists in the answer for demonstration.
