Single-user versus multi-user installations
During the installation of Worklight, you choose to install WebSphere Application Server Liberty Profile. This server is either a multi-user or single-user installation, depending on how you installed IBM Installation Manager.
Administrator Installation Manager installed using install.sh. Requires administrator privileges. Produces multi-user installations of products. Single-user Installation Manager installed using userinst.sh. Only the user who installed can use it.
In multi-user mode, different users can run the server in sequence, but not at the same time. There can only be one server process running, because the server is configured to attach to a specific network port.
If you use a pre-installed application server when installing Worklight server, the following constraints regarding user accounts on UNIX apply:
- If pre-installed application server is owned by a non-root user, you can install Worklight in either of two ways:
- Through a single-user installation of Installation Manager as the same non-root user.
- Through an administrator installation of Installation Manager, as root, and afterwards change the owner of all files and directories added or modified during the installation to that user. The result is a single-user installation.
- If pre-installed application server is owned by root, you can install Worklight only through an administrator installation of Installation Manager; a single-user installation of Installation Manager does not work, because it lacks the necessary privileges.
