## Cherokee Bundle: cherokee-tweak

This command-line tool is also not as well known as it would. Again this is not by lack of merits, which in fact are considerable. Its intended audience are also system administrators and developers.

`cherokee-tweak` is a swiss army knife that allows to perform several administrative tasks from the command line. It can connect to a running Cherokee instance, be it in the local computer or at a remote location, and request it to perform several actions.

These actions are:

- Log rotation: `logrotate`.

- Live tracing: `trace`.

- Provide information: `info`.

This is the full information provided by the manpage.

NAME

  cherokee-tweak - Command-line interface to the Cherokee administrative interface

SYNOPSIS

  cherokee-tweak -c command -a url [options]

DESCRIPTION

  cherokee-tweak connects to running cherokee instance, either local or remote, and requests it to perform one of several actions.

OPTIONS

  cherokee-tweak accepts the following options:

  -h, —help

    Shows brief usage information

  -V, —version

    Prints version and exits

  -u, —user= STRING

    Specifies the user name with which to identify to the server

  -p, —password=STRING

    Specifies the password with which to identify to the server

  -c, —command=STRING

    Required option. Command to execute: logrotate, trace or info

  -a, —url=URL

    Required option. URL where the administrative interface can be found. This target must be defined previously in cherokee- admin, enabling a "Remote Administration" type handler (Virtual Servers→Behaviour→Add new rule, and then Handler→"Remote Administration"). The definition of a security mechanisim is highly encouraged.

  -l, —log=PATH

    Log file to be rotated (Only to be used when -c is logrotate)

  -t, —trace=STRING

    Modules to be traced (Only to be used when -c is trace). Chero‐ kee must have been compiled with the —enable-trace for this to work. Everything traceable with CHEROKEE_TRACE can also be traced this way.

To use `cherokee-tweak`, an administrative interface must be defined within cherokee-admin. That is, you must define a path managed by the handler `Remote Administration`. This can be done through the Virtual Servers option, in Behaviour and using the Add new rule option.

Please note that while you are at it, the definition of a security (through the Security tab) is highly encouraged. Although you have the choice to, you should never use None as security mechanisim since this would leave your system exposed to third parties using `cherokee-tweak`.

Also note that the usage of the `trace` command has no effect unless Cherokee is compiled with the `—enable-trace`. This is a debugging option and it is unlikely to be present in binary version of Cherokee not specifically compiled with this in mind.

Every module traceable with CHEROKEE_TRACE can also be traced this way. Refer to the "Debugging" section of the documentation for more information on this matter.

Keep in mind one important thing: when the `-t` option is specificed, `cherokee-tweak` activates the tracing functionality within the `cherokee` instance. It does not provide tracing of its own. This means the debugging information will appear in the machine that is actually running the `cherokee` instance. This may or may not be the same that is running the `cherokee-tweak` process.
