Linux provides the highest performance UnitedChart systems.
If a client/server data base is employed, UnitedChart can handle
Use the following steps to download, install, remove,
and start/stop/restart the UnitedChart Linux server software.
Select a system directory to contain your UnitedChart system.
One option would be to create an account called UnitedChart.
That creates the directory /home/UnitedChart which could be used
to contain your system.
Another approach would be to create the folder UnitedChart in
your desired location (ex: mkdir /home/example/UnitedChart).
The directory does not have to be named UnitedChart,
but it will in the following instructions so substitute
if you use a different directory name.
The computer server you select to host your UnitedChart system:
- Should have at least 32 gigabytes of
available mirrored disk storage.
- Should have a static ip address.
- Should have an uninteruptible power supply (UPS).
- Have a recent 64-bit version of Linux.
To install UnitedChart on your Linux computer server:
- Create your system directory.
- Download the uchart binary
into the /home/UnitedChart system directory.
- Login to the console command line interface or through a terminal
and change to your system directory (ex: cd /home/UnitedChart).
Avoid clicking on the binary through a desktop interface
because if there is a problem the error message will
probably dissappear, while it remains if you use the
- Create your system by starting the UnitedChart server
(ex: ./uchart). If it refuses to run you probably
need to give it execute authority with the command
chmod 750 uchart
- The first time UnitedChart is run it creates an initial
system of directories, data bases, and configuration files.
If there is an error, the message is displayed and the server
is not started.
- If there are no startup errors, the UnitedChart server
console will appear showing startup information.
Also displayed is the ip address to access the server.
- When UnitedChart is first started it guesses the ip address.
If there is more than one ip address and the wrong one was
selected, terminate the server using ctrl-C, edit ls.txt
with your favorite TEXT editor and add the following line:
If :portNum is left off then port number 80 is used.
Then start up the server as before.
Check that the ip address you specified appears.
- Go to a computer, phone, or tablet that is connected
to the same network as your UnitedChart Linux server.
Start the Internet browser (Chrome, Safari, etc.)
and type in the location displayed on the UnitedChart
console. The login interface should appear.
- Setup your system by logging in as system manager
using these instructions.
Uninstall UnitedChart Linux server
To remove UnitedChart, delete the UnitedChart directory
you created to contain your UnitedChart system.
UnitedChart never writes outside of its folder,
so deleting it uninstalls it.
Start/stop/restart UnitedChart Linux server
There are many ways to run UnitedChart on Linux.
It is up to the server's manager to decide.
One method is to login to the console or through a terminal
and manually start UnitedChart so the transactions can be observed.
Another method would be to run UnitedChart in background
with a command like:
./uchart & >/dev/null
UnitedChart can also be setup to run as a traditional service.
