Subject [jira] Commented: (QPID-1114) Improvements to daemon mode operations
Date Tue, 03 Jun 2008 18:12:44 GMT

    [ https://issues.apache.org/jira/browse/QPID-1114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602010#action_12602010
] 

Ted Ross commented on QPID-1114:
--------------------------------

There is one more issue that arose from these changes...

The data directory (--data-dir option) defaults to /var/lib/qpidd.  The installation script
creates this directory and sets its owner to qpidd:qpidd.  If a user installs qpidd and then
runs the broker from the command line, the broker will fail because the user does not have
write access to the data directory.

I will shortly commit a change that addresses this problem by:

1) Using $HOME/.qpidd as the default data directory (and creating it if it doesn't exist)
2) Using the same as the default PID directory
3) Adding --data-dir /var/lib/qpidd to the command line in the startup script

> This update improves daemon-mode operation of the C++ broker.
> When run as a daemon (--daemon), the broker currently creates a PID file specific to
the port the broker is listening on.  This allows multiple daemons to run simultaneously on
the same system.  The PID file is stored in "/var/run" if the broker is running as root, otherwise,
it is stored in "/tmp".
> The problem with this is that since it is recommended that the broker not run as root
for security reasons, installed/deployed brokers write their PID files to /tmp.  This is not
the right place for such a file and may run afoul of the security policy on the system it
is installed on.  It also means that root users can't use the --quit option to stop daemons
that were started by non-root users.
> This update does the following:
> 1) Removes the root/not-root distinction and always defaults to "/tmp".  This is useful
for developers who run the broker from SVN and not as a service.
> 2) Provides a new option "--pid-dir" that allows the configuration (command line, file,
or env-variables) to control the directory for PID file storage.
> 3) Adds a line to the default configuration file (/etc/qpidd.conf) that sets the pid-dir
to "/var/run/qpidd".  This is useful for real deployment.
> 4) Adds commands in the install spec-file to create /var/run/qpidd with read and write
access for user "qpidd"
