The installation can only be performed by a user with administrative privileges. On some operating systems, you can double click on the installer file icon to begin installation. Depending on your operating system you may be prompted for your password or asked to allow the installation to be performed.
- On Windows systems, you may need to right click on the installer file icon, and choose to Run as administrator.
- On Linux, you would normally install to a central location, which will involve running the installation script as an administrative user - either by logging in as one, or by prefacing the command with sudo. Please check that the installation script has executable permissions before executing it.
Next, you will be asked where to install the software (figure 2.1). If the installer has detected that a version of the software is already installed, an option to update the existing installation or install to a different directory will be offered (figure 2.2). For standard upgrades of the CLC Server, you should choose to update the existing installation.
The directory the software is installed into will be referred to as the server installation directory throughout the rest of this manual.
The installer allows you to specify the maximum amount of memory the CLC Server will be able to utilize (figure 2.3). The range of choice depends on the amount of memory installed on your system and on the type of machine used. If you do not have a reason to change this value, leave it at the default setting.
If you are installing on a Linux system, you are offered the option to specify a user account that will be used to run the CLC Server process. Having a specific, non-root user for this purpose is generally recommended. On a standard setup, this would have the effect of adding this username to the
systemd service unit file describing the CLC Server service, and setting the ownership of the files in the installation area to this user. Downstream, the user running the CLC Server process will own files created in File Locations, for example, after data import or data analyses.
If you are installing the server on a Windows system you will be able to choose if the service is started manually or automatically by the system.
The installer now extracts the necessary files.
On a Windows system, if you have chosen that the service should be started automatically, the service should also start running at this point.On Linux or Mac, if you have chosen the option to start the system at the end of installation, the service should also have started running. Please note that if you do not already have a license file installed, then the CLC Server process will be running in a limited capacity at this point. Downloading a license is described in section 2.6.
Information on stopping and starting the CLC Server service is provided in section 2.7.
