Detecting Previous Installation

For any previous installation, the installation agent is able to detect the existing configuration and its data library. In this case, you just have to move the existing configuration and data library, or you can remove it if you no longer need it. Below shows an example detection:

[[email protected] ~]# wget -q -O - https://agents-api.s9s.io/static/install/linux.sh | bash -s -- install xxxxxxx-bbbbb-4617-bbbb-ssssssss mysql://s9s:[email protected]:3306 agent-auth-api.s9s.io:443
=> Pre-installation check has failed (token found in configuration).

An existing or previous installation has been detected,
Please make sure you backup and remove the following
 files and directories first:
- /etc/bartender.yaml
- /var/lib/backup-agent/

Aborting installation.
[[email protected] ~]# rm -rf /etc/bartender.yaml /var/lib/backup-agent/
[[email protected] ~]# wget -q -O - https://agents-api.s9s.io/static/install/linux.sh | bash -s -- install xxxxxxx-bbbbb-4617-bbbb-ssssssss mysql://s9s:[email protected]:3306 agent-auth-api.s9s.io:443
=> Using "yum" package manager
=> Repo file "/etc/yum.repos.d/bar-repo.repo" already exists
