How to delete the rpm installation source, how to downgrade the yum installation
yum info zabbix-server-mysql #Shows a low version, the default source version
rpm -ivh zabbix-release-3.4-1.el6.noarch.rpm #Installed a new source, a higher version of the source
(You can rebuild the yum cache: yum makecache)
yum info zabbix-server-mysql #Displayed as a higher version
yum install zabbix-server-mysql #installation
[root@june-test-11 june]# rpm -q zabbix-server-mysql
zabbix-server-mysql-3.4.8-1.el6.x86_64
shows that a higher version is installed
yum info zabbix-server-mysql #Shows that a higher version is installed
rpm -q zabbix-release
zabbix-release-3.4-1.el6.noarch
Show the registration of the installed higher version
rpm -e zabbix-release
Remove this higher version installed
rpm -q zabbix-release
package zabbix-release is not installed
yum erase zabbix-server-mysql
successfully deleted
yum info zabbix-server-mysql
Test result: Sure enough, only the low version is left, returning to the original state of the system
summary:
1. Remove the package
yum erase zabbix-server-mysql
2. Delete the source installed by rpm
rpm -e zabbix-release
Here we must pay attention to use rpm -q to find the deleted name first, otherwise it will report that the deleted package cannot be found.
