Stats page

Common problem:

⭕ If some not working - check SELINUX:

sestatus

If SELINUX is enabled - switch off this: open /etc/selinux/config and change SELINUX to disabled:

sudo sed -i s/^SELINUX=.*$/SELINUX=disabled/ /etc/selinux/config

⭕ Cannot chroot1

[/usr/sbin/haproxy.main()] Cannot chroot1(/var/lib/haproxy)  

Solution:

• Create /var/lib/haproxy directory
• Check on the rpcbind service to ensure that this service is started

⭕ Failed to download metadata for repo ‘AppStream’ (CentOS8/9)

Solution:

cd /etc/yum.repos.d/
sudo sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sudo sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
