Query re: order of yum update and yum install
I am new to Linux and just installed a server on a local box. Everything appears to be running smoothly. I have used the 'yum' script to get a webserver up and running, installing vsftpd, php and mysql.
Two questions :
1. How do you know if a package is a 'group' or an individual script? For instance, I use 'yum groupupdate "MySQL Database"' but 'yum update php'. I guess I am wondering if the system will let you run a simple 'update' on one script in a [group]. Does it warn you that you should be running a groupupdate on [package group]?
2. When doing 'yum install' and 'yum update', is the proper sequence to update first and then install or the opposite?
Thanks for your patience and time.
