I don't know why but apache 2 has its own directory. So you have
to add
the following to your $PATH:
/opt/local/apache2/bin
And this must be put before /usr/sbin in the PATH, as otherwise
the result remains the same …
To find out which version of an application is used you can use the
following command. This prints the path to the application.
which apachectl
This command uses PATH, because of which the order is important!
Yes, that must be the problem, but how do I fix it? I made a new
order like so:
/opt/local/bin:
/opt/local/sbin:
/opt/local/apache2/bin:
/opt/local/bin/mysql5:
/opt/local/lib/mysql5/bin:
/opt/local/lib/mysql5/bin/mysql:
/opt/local/lib/mysql5/bin/mysqladmin:
/bin:
/sbin:
/usr/bin:
/usr/local/bin:
/usr/local/mysql/bin:
/usr/sbin
Note that there's no use in listing /opt/local/lib/mysql5/bin/mysql
and /opt/local/lib/mysql5/bin/mysqladmin in your PATH. PATH can only
hold directories, and those are files. You can safely remove those
two items, since the directory they're in is already in your PATH.
and entered that in the terminal:
export PATH=/opt/local/bin:/opt/local/sbin:/opt/local/apache2/bin:/
opt/local/bin/mysql5:/opt/local/lib/mysql5/bin:/opt/local/lib/
mysql5/bin/mysql:/opt/local/lib/mysql5/bin/mysqladmin:/bin:/sbin:/
usr/bin:/usr/local/bin:/usr/local/mysql/bin:/usr/sbin
Ok, so you have thus set the PATH for that instance of the Terminal.
But that goes away as soon as you close that Terminal window.
But even after a restart, the path is still in the wrong order:
echo $PATH
/opt/local/lib/mysql5/bin/mysql:/opt/local/bin/mysql5:/usr/local/
mysql/bin:/opt/local/bin:/opt/local/sbin:/opt/local/lib/mysql5/bin:/
usr/local/bin:/bin:/sbin:/usr/bin:/usr/sbin:/opt/local/bin:/opt/
local/lib/mysql5/bin/mysqladmin:/opt/local/lib/mysql5/bin/mysql
/opt/local/lib/mysql5/bin/mysql;
/opt/local/bin/mysql5;
/usr/local/mysql/bin;
/opt/local/bin;
/opt/local/sbin;
/opt/local/lib/mysql5/bin;
/usr/local/bin;
/bin;
/sbin;
/usr/bin;
/usr/sbin;
/opt/local/bin;
/opt/local/lib/mysql5/bin/mysqladmin;
/opt/local/lib/mysql5/bin/mysql
If you want the PATH to be persistent, you have to put the "export"
line in a file that the Terminal reads when it starts.
I don't quite understand how this comes about: I'm not even sure
where many of these values come from. Based on what I've googled, I
gather that these variables are specified in the system and user
profile files. But if I ask 'pico /etc/profile', I get:
-----------------------------------------------------------
PATH="/opt/local/bin:/opt/local/sbin:/opt/local/lib/mysql5/bin:/usr/
local/bin:/bin:/sbin:/usr/bin:/usr/sbin"
export PATH
if [ "${BASH-no}" != "no" ]; then
[ -r /etc/bashrc ] && . /etc/bashrc
fi
-----------------------------------------------------------
Similarly, 'pico ~/.profile' produces:
-----------------------------------------------------------
#
# Your previous .profile (if any) is saved as .profile.dpsaved
# Setting the path for DarwinPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
-----------------------------------------------------------
So that should ensure that the /opt/local/bin path always comes
first, right? Your help is greatly appreciated: UNIX for Dummies
(3rd edition) is not much help here.
It sounds like at some point you modified /etc/profile, and
~/.profile, to contain those /opt/local directories (since they would
not have been there by default) but that there's another file that
the terminal is using instead of those. Possibilities include /etc/
bashrc, ~/.bash_profile and ~/.bashrc. That's assuming your shell is
bash. Is it? Find out with "echo $SHELL".
