Use rpmdb and yum in RedHatLinux to solve dependency problems

Rpmdb and yum are used to solve the dependency problem.

Use rpmdb and yum to solve dependency problems

The rpmdb package has been canceled in rhel5 (in fact, it has been canceled in fc4). rpmdb mainly solves the dependency during the installation package.

Use the following method to check whether the rpmdb package is installed.

[Root @ linux RPMS] # rpm-qa | grep rpmdb
Rpmdb-RedHat-4-0.20050107

How can we use rpmdb to solve dependencies? For example, when installing apache that comes with as4, there are many dependencies to solve, such:

[Root @ linux RPMS] # rpm-ivh httpd-2.0.52-9.ent.i386.rpm
Warning: httpd-2.0.52-9.ent.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
Error: Failed dependencies:
Httpd-suexec is needed by httpd-2.0.52-9.ent.i386
Suggested resolutions:
Httpd-suexec-2.0.52-9.ent.i386.rpm
Install the dependency package when an error is reported. The rpmdb tool automatically solves the dependency by executing rpm-ivh rpmdb *. rpm,

Add the -- aid parameter when installing other software packages.

[Root @ linux RPMS] # rpm-ivh -- aid httpd-2.0.52-9.ent.i386.rpm
Warning: httpd-2.0.52-9.ent.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e

2: httpd-suexec ##################################### ###### [100%]
The installation is complete.

Now there is no rpmdb tool, and you can use the new yum tool.

The installation of the component package is completed through yum, so you need to configure yum.

Perform the following operations on the command line:

1. mount-o loop rhel-5-server-dvd.iso/media/rhel

2. vi/etc/yum. repos. d/rhel-local.repo

[Cluster]
Name = Red Hat Enterprise Linux $ releasever-$ basearch-Cluster

Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

Name = Red Hat Enterprise Linux $ releasever-$ basearch-ClusterStorage
Baseurl = file: // media/rhel/ClusterStorage

3. mkdir-p/var/rhel/{Cluster, ClusterStorage, Server, VT}
