Every linux distro is slightly different. This guide is intended to cover the basics and show you around some of the ways you can configure and work with CrushFTP.
The assumption is that you are doing this install headless.
First, make sure Java is installed properly. By default most linux distros come with an open source version of Java that may not work with CrushFTP. Make sure its an official OpenJDK java, or other suitable JVM.
If it mentions GNU, it is not the right one.
To run Java, you may need to specify the full path to the java binary. Something possibly like /usr/java/jre1.5.0_11/bin/java. Its going to depend on where you installed it.
Start / Stop CrushFTP
There is a script provided to give you the basics of starting and stopping CrushFTP. It might be overkill for your situation, but you are welcome to use it and modify it for your needs. The script is crushftp_init.sh. Its included with your download of CrushFTP already. You must edit the script the first time you use it to set the correct path in it.
./crushftp_init.sh start ./crushftp_init.sh stop
Generating an Admin User
While you technically can do everything with CrushFTP from the command line and editing text XML files, its much easier to use a web browser to do this. You just need to have an admin user created first.
To make your user for doing this, use a command like this:
java -jar CrushFTP.jar -a "crushadmin" "password"
This will make a new user, and write it to the default location:
You can now login to the administration console using a web browser. The default ports are:
Alternate Start /Stop CrushFTP Methods
You may also want to start it so it stays running even when you logout.
sudo nohup java -jar CrushFTP.jar -d&
The "-?" option will list various command line options you can use:
java -jar CrushFTP.jar -?
To kill CrushFTP, you can do it one of two ways. The standard kill method will definitely work in stopping the server. Its safe to use as CrushFTP takes precautions against issues that could arise.
You can also do it from a script. CrushFTP supports the "SITE QUIT" command if it has been enabled in the User Manager under the Admin tab for a user. So you can have a scripted command that simply logs into the server, issues SITE QUIT, then logs out. The server will then gracefully quit saving any unsaved data to disk before exiting.
Here is an example shell script to login with FTP with a provided script:
#!/bin/sh ftp -n < ftp.txt
You would then put the following into a ftp.txt file:
open 127.0.0.1 quote user crushadmin quote pass password quote site quit quote quit
Provided a user named "crushadmin" exist, and they have permission to execute that command, CrushFTP will terminate once the user logs out.
Generating a Password With CrushFTP from the Command Line
CrushFTP supports a "-p" option to encrypt a password. This is especially useful if you are manipulating CrushFTP user.xml files directly.
java -jar CrushFTP.jar -p DES thePassword
