I have installed yum package "mysql" previously using :
yum install mysql
However when I try and list installed packages using filter:
yum list install *mysql"
It shows nothing but when I list installed packages without I can see package names which I believe is what my mysql installed:
mariadb.x86_64 1:5.5.65-1.el7 @gl mariadb-libs.x86_64 1:5.5.65-1.el7
Does yum have a concept of short names or aliases? just trying to understand how mysql maps to mariadb.exe and have googled various resources but didn’t find anything obvious.
RPM packages can declare
Provides: which mean that they provide some named capability. These are treated as equivalent to package names when yum decides what packages to install.
A recent version of the
mariadb package does indeed declare several provides:
$ rpm -q --provides mariadb config(mariadb) = 3:10.4.13-2.fc32 mariadb = 3:10.4.13-2.fc32 mariadb(x86-64) = 3:10.4.13-2.fc32 mysql = 3:10.4.13-2.fc32 mysql(x86-64) = 3:10.4.13-2.fc32 mysql-compat-client = 3:10.4.13-2.fc32 mysql-compat-client(x86-64) = 3:10.4.13-2.fc32
Packages can also declare
Obsoletes: which are packages that the current package replaces. (Though this package doesn’t declare any.) If a package with the old name is already installed, running
yum upgrade will replace the old package with the new one.
