Question
How to make a certain yum repository uses a proxy without changing the global yum configuration /etc/yum.conf or affecting other yum repository.
Answer
Add the proxy url into the certain repository only.
Example:
Below is a zabbix.repo without proxy configured into it:
[/>] # cat /etc/yum.repos.d/zabbix.repo [zabbix] name=Zabbix Official Repository - $basearch baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 [zabbix-frontend] name=Zabbix Official Repository frontend - $basearch baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontend enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 [zabbix-debuginfo] name=Zabbix Official Repository debuginfo - $basearch baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/debuginfo/ enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 gpgcheck=1 [zabbix-non-supported] name=Zabbix Official Repository non-supported - $basearch baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/ enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX gpgcheck=1
Below is a zabbix.repo with proxy (highlighted) configured into it:
[/>]# cat /etc/yum.repos.d/zabbix.repo [zabbix] name=Zabbix Official Repository - $basearch baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 proxy=https://proxy.example.com:3128 [zabbix-frontend] name=Zabbix Official Repository frontend - $basearch baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontend enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 proxy=https://proxy.example.com:3128 [zabbix-debuginfo] name=Zabbix Official Repository debuginfo - $basearch baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/debuginfo/ enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 gpgcheck=1 proxy= proxy=https://proxy.example.com:3128 [zabbix-non-supported] name=Zabbix Official Repository non-supported - $basearch baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/ enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX gpgcheck=1 proxy= proxy=https://proxy.example.com:3128
