For multiple instances, please use only absolute paths and unique names to all the files referenced in the configuration file of each CHARON-AXP instance (log, toy clock, rom files and all the other data such as disk images [Exception: clustering] - all these objects will be explained later in this document) and check the hardware devices (the CDROM drive for example) are used by only one instance at a time (not shared).

Example:

...

1. Copy the sample script "/opt/charon/bin/charon.service" ( "/opt/charon/bin/charon" for Red Hat  Linux 6.x) to the "/usr/lib/systemd/system/" directory (or to your home directory for Red Hat Enterprise Linux 6.x).

   Example:

   Red Hat Linux 6.x	$ cp /opt/charon/bin/charon /my_services/es40_service $ chmod 755 /my_services/es40_service
   Red Hat Linux 7.x and CentOS 7.x	$ cp /opt/charon/bin/charon.service /usr/lib/systemd/system/es40.service $ chmod 755 /usr/lib/systemd/system/es40.service

   
   

2. Edit the renamed file to replace sample values of the following parameters.

   Example:

   Red Hat Linux 6.x	exec="/opt/charon/bin/es40" prog="my_es40" config="/my_services/es40-service.cfg"
   Red Hat Linux 7.x and CentOS 7.x	ExecStart=/opt/charon/bin/es40 -d /my_services/es40-service.cfg WorkingDirectory=/my_services

    "my_es40" is a service name in the example above

             

3. Create and edit the configuration file ( "/my_services/es40-service.cfg" in the examples above) the way it was described before and make sure the following pre-requisites are met:

   • OPA0 must be configured as a virtual port or physical console, not as an operator console.

     Example:

     set COM1 alias=OPA0 port=10003 #set COM1 alias = OPA0 line = (console)

     
     

   • Use only absolute paths to log, toy clock, nvram files and all the other data such as disk images, etc. The names of the references files must be unique.

     Example:

     ... set session log="/CharonInstances/1st_es40.log" set rom container="/CharonInstances/1st_es40.bin" set toy container="/CharonInstances/1st_es40.dat" set PKA container[0]="/CharonInstances/1st_es40_boot_disk.vdisk" ...

     
     

   • Make sure the same physical devices are not used by other CHARON-AXP daemons and the OPA0 console port number is unique across the CHARON server.
     
     

...

Once the configuration file is ready, execute the following commands (based on the examples above) to install and start CHARON-AXP as a daemon:

...

To stop a CHARON-AXP daemon, use the following commands.

Example:

Please note that before stopping a CHARON-AXP service, a clean shutdown of the operating system running on the virtual machine has to be performed.

...

To remove a CHARON-AXP daemon use the following commands.

Example:
