[SOLVED] installing packages

[st_ewart]

Hey,

I'm working with a semi-dedicated server with CentOS installed. I'm trying to install a mail server following these instructions How to set up a mail server on a GNU / Linux system

As I'm newish to Linux I'm having problems installing packages using commands for Ubuntu. I tried installing the apptitude package using - 'yum makecache' then 'yum apt' but when I type aptitude at the command line it doesn't recognise it?

Thanks in advance for any help (and patience)

You should be able to pretty much replace the 'apt-get' that you're used to with 'yum install', the CentOS equivalent. Just make sure that you run the installer as root.

Alternatively you could install yumex (i.e. 'yum install yumex') and install packages with a nice gui tool.

You said centOS, so here is a link for a goldmine of information on redhat systems.

Red Hat Enterprise Linux

it also has a section on setting up mail stuff and whatnot.

That 'Red Hat Enterprise Linux' link shows everything with a GUI. I'm connecting remotely using SSH so it isn't much help.
Basically I'm asking how to execute the following Ubuntu command on centOS,
'aptitude install mysql-client mysql-server',
I should probably mention that my Ubuntu knowledge isn't great either!
thanks again

you could try yum install mysql-client mysql-server

I get this with yum install mysql-client mysql-server.....

I assume that means it couldn't find the package where ever it looked?

Whenever you want to find a package, you can do:

yum list available|grep <part_of_the_name>

it can take several seconds until the output is seen, but it will shorten the list. The 'grep' command does a case sensitive search, but most packages are in lower case.

For MySQL, try:

yum list available|grep sql

that should reveal the package name for you.

[meton_magis]

yum list available | egrep -i sql

the egrep is unnessisary (though i prefer it because it extends the regex) but the -i make it search ignoring case sensitivity. but you could just do

yum search mysql

and it would do the same. If your not using regex special charecters (.*$^[^]{,}) or whatever else, than grep is just another process that the command has to go through. for something this small the cpu usage is irrelivant, but since i do alot of scripting, i try to squeze out all the efficiency i can, and it's always fun to learn stuff
