Appendix A Installing Software

Below are a few methods to locate and install required packages. You may use any one of theses methods as necessary.

Always verify that intended installations were successful, especially when using the wildcard character!

Using yum

1. Ensure the file /etc/yum.repos.d/server1.repo exists on your system. If does not, download the file from server1:

[root@stationX]# cd /etc/yum.repos.d/
[root@stationX]# wget http://server1/pub/gls/server1.repo

It should contain the following content:

[Server]
name=Server
enable=1
gpgcheck=1
baseurl=http://192.168.0.254/pub/Server

2. After writing the file to disk, and returned to your prompt, enter the following command. You should see output similar to that listed below.

# yum list redhat-release

3. If your results are similar, you must now install the public GPG keys(note the asterisk):

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat*

4. You may now use the command listed below to install software:

# yum -y install packagename

Using NFS (may use the "*" wildcard in RPM name)

1. You may use the following commands to access and install software via NFS.

2. # mkdir /mnt/server1

3. # mount -t nfs -o ro server1:/var/ftp/pub/ /mnt/server1

4. # rpm -Uvh /mnt/server1/Server/packagename

Using FTP (may use the "*" wildcard in RPM name)

1. You may use the following command to access and install software via FTP.

2. # rpm -Uvh ftp://server1/pub/Server/packagename

Using HTTP (may NOT use the "*" wildcard in RPM name)

1. You may use the following command to access and install software via HTTP.

2. # rpm -Uvh http://server1/pub/Server/packagename
