Suppose that we have a RHEL5 machine running and we want to install MariaDB on it. Unfortunately, it conflicts with files installed by the mysql package. # rpm -i MariaDB-5.5.28a-centos5-x86_64-common.rpm warning: MariaDB-5.5.28a-centos5-x86_64-common.rpm: Header V3 DSA signature: NOKEY, key ID 1bb943db file /etc/my.cnf from install of MariaDB-common-5.5.28a-1.x86_64 conflicts with file from package mysql-5.0.77-4.el5_6.6.x86_64 file /usr/share/mysql/charsets/Index.xml from install of MariaDB-common-5.5.28a-1.x86_64 conflicts with file from package mysql-5.0.77-4.el5_6.6.x86_64 file /usr/share/mysql/charsets/cp1250.xml from install of MariaDB-common-5.5.28a-1.x86_64 conflicts with file from package mysql-5.0.77-4.el5_6.6.x86_64 file /usr/share/mysql/charsets/cp1251.xml from install of MariaDB-common-5.5.28a-1.x86_64 conflicts with file from package mysql-5.0.77-4.el5_6.6.x86_64 Unfortunately, a lot of other packages require the mysql package. What is a good approach to solving this problem? Thanks
