# fix repositories
sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/*.repo

sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/*.repo
echo "sslverify=false" >> /etc/yum.conf
yum makecache fast

# install EPEL and SCL repo
yum install -y epel-release centos-release-scl

# fix repos again
sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/*.repo
sed -i s/^#.*baseurl=http/baseurl=http/g /etc/yum.repos.d/*.repo
sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/*.repo

# install python 3.8
yum install -y rh-python38

# symlink SCL python to PATH so Ansible can discover it
ln -sf /opt/rh/rh-python38/root/usr/bin/python3 /usr/bin/python3
ln -sf /opt/rh/rh-python38/root/usr/bin/pip3 /usr/bin/pip3

# install deps in Ansible as required, for example to manage MySQL correct package is rh-python38-python-PyMySQL
