mongodb @2.6.5_1: Run mongod instance with config file

[moderndeveloperllc (Mark Garrett)]

As indicated in the documentation, it is preferred to run the mongod instance via the config file, not command line parameters: ​http://docs.mongodb.org/manual/reference/program/mongod/#cmdoption--config

I've attached a sample mongod.conf file that replicates the existing options - plus one SSL option now mongodb compiles with --ssl by default. I'm not sure how MacPorts handles default config files when installing or updating ports. I imagine that you would want to create mongod.conf if it doesn't exist, but name it mongod-default.conf if one does exist as to not overwrite user-defined parameters that might be needed for the instance to start.

Sample mongod.conf file

Perhaps the port file could be changed to something like:

startupitem.executable  sudo -u ${mongouser} ${prefix}/bin/mongod --config ${prefix}/etc/mongodb/mongodb.conf

post-activate {
    if {![file exists ${prefix}/etc/mongodb/mongod.conf]} {
        file copy ${prefix}/etc/mongodb/mongod.conf.sample \
            ${prefix}/etc/mongodb/mongod.conf
    }
}

The above attached file replicates the existing startup item (with SSL added). Moving to config file would make it quite a bit easier for those of us who need to add ​other startup options.

Version 3 has the same config structure, so the above change should still work.

Sorry for the noise; I did not realize that hitting the "CcMe!" button would also add a comment to the thread.

I'm trying to get this to work, but I'm running into an error that I'm not sure how to resolve.

I made the following changes:

​https://github.com/todofixthis/macports-ports/commit/627f0f166bcf381bdfda39dcaedf054a0a7242ad

• Added mongodb.conf.sample to ${portpath}/files.
• Added the following to Portfile:

post-activate {
    if {![file exists ${prefix}/etc/mongodb/mongodb.conf]} {
        file copy ${filespath}/mongodb.conf.sample \
            ${prefix}/etc/mongodb/mongodb.conf
    }
}

• cd ${portpath}
• sudo port install

This is the error that I get (note: /private/tmp/mongodb is the directory containing the Portfile):

:debug:activate Executing proc-post-org.macports.activate-activate-0
:error:activate org.macports.activate for port mongodb returned: error copying "/private/tmp/mongodb/files/mongodb.conf.sample" to "/opt/local/etc/mongodb/mongodb.conf": no such file or directory
:debug:activate Error code: NONE
:debug:activate Backtrace: error copying "/private/tmp/mongodb/files/mongodb.conf.sample" to "/opt/local/etc/mongodb/mongodb.conf": no such file or directory
    while executing

    ("eval" body line 1)
    invoked from within
"eval $post $targetname"
:info:activate Warning: targets not executed for mongodb: org.macports.activate

I confirmed that /private/tmp/mongodb/files/mongodb.conf.sample does exist.

I think the error is indicating that it can't copy the file to /opt/local/etc/mongodb because that directory doesn't exist, but even if I add xinstall -d ${prefix}/etc/mongodb to the Portfile, I still get the same error.

I'm not sure how to continue; any ideas?
