I have installed mojolicious by the following commands
$ sudo su
# curl get.mojolici.us | sh
Unfortunately, when I run morbo to test my app, I am given an error stating that the command is not found. I then ran
cpan install Mojolicious
and it gives me the following output
Reading '/home/lucas/.cpan/Metadata'
Database was generated on Sun, 06 Oct 2013 19:07:27 GMT
Mojolicious is up to date (4.45).
Why will morbo not work? I have tried using hypnotoad as well, but it does not work either.
CPAN-installed binaries often end up in a different location, subject to your distribution and install method. For example, on my machine the location is:
/usr/bin/site_perl/morbo
In my .bashrc I have:
export PATH="/usr/bin/site_perl:$PATH"
If you add this and log out and back in (or type . .bashrc) you'll find that the command morbo works fine.
If it's in a different location, run updatedb (as root, if needed) and locate morbo to find out where it is, and add the appropriate path to your bash/shell config.

I want to write a .sh-script that sends a message to my ejabberd-account. (the script is "called" by the apache2 standard-user "www-data").
The script should execute the following command: ejabberdctl send_message chat admin#my-domain user#my-domain "title" "my message"
However, I can't run any ejabberdctl command without "being" root. So sudo ejabberdctl is not working (in terminal or any .sh-script). I can only do sudo -s followed by ejabberdctl my-command, which doesn't work in .sh-scripts (or am I wrong?).
(I've installed ejabberd 20.07 on ubuntu 20.04 with the help of this tutorial: Install Ejabberd...)
Is there a way to run a command in a .sh-script as "real root" or to create a root-session and run the command there (like I do manually with sudo -s ...)?
Is there any solution to my problem or should I install ejabberd the "normal way"?
When ejabberd is compiled and installed from source code, it's possible to prepare it with something like
./configure -–enable-group=ejagroup
Then, you can simply create the system group ejagroup, and add the www-data user to that ejagroup.
See https://docs.ejabberd.im/admin/installation/#options
In your case, that you use the Debian package from ProcessOne, I see the tutorial mentions that you create a system account called ejabberd. Maybe you can run ejabberdctl from that account, no need to be root?
I still don't know why I can only run ejabberdctl when I'm "logged-in" as root (sudo ejabberdctl is still not working)
Is my .bashrc file wrong? (last line: PATH=$PATH:/opt/ejabberd-20.07/bin/)
Anyway, at least I can run sudo /opt/ejabberd-20.07/bin/ejabberdctl my_command with any user, like they did here: Ejabberd sbin/ejabberdctl start (No such file or directory)
Has someone else experienced this weird behavior with sudo: any_command: not found ?
Let me know if you have a more "elegant" solution to my problem.
I am new to Perl. I'm building a plugin for Cpanel to install SSL certificates when the user clicks an option.
I have to execute a command as root inside the Perl code. How can I do this?
So basically you need to run a system command as root user from within a Perl script.
You can use the system built-in function with a sudo inside it. This will fork a new process where the command will be executed while the parent process waits, and then return the exit status of that command.
For example, this basic command switches to root and prints the current user :
perl -e 'system("sudo su -c whoami")'
Obiously, it outputs this on the standard output :
root
Notes :
for this to work, you need you application user to be able to switch to root(without the need of typing a password) ; some could consider that a security breach (some attacker that would have taken over your application would be able to cause fatal damage to your system)
the actual command to switch to the root user might vary depending on your OS ; the one I used in the example you is for RedHat
I searched the CPAN for modules that provide the "switch to root" functionality and the only one I found is Sudo ; I didn't try it, but it that was not updated since 2013 and has few issues pendings since 3 to 9 years
I have to take quite a few steps before I get into the file I need to be, which is why I'm trying to set up an alias in my terminal, that gets me to the file by running that alias.
The following steps are needed to arrive where I have to be:
cd Sites
vagrant ssh
cd /var/www/miniportal.billetten.dk/logs/
sudo -s
cd /etc/apache2/sites-available/
nano 25-av_miniportal.conf
Edit line 33 in that file (I guess it's possible to jump to that line)
I tried setting up an alias like this, but the problem is that it stops running the rest of the command after I SSH'd into Vagrant. if I manually exit Vagrant, it continues the command (and of course returns an error, because there is no such folder).
The question is: How do I make sure that everything from step 3 is executed AFTER step 2 is done logging in through SSH?
My ultimate goal is to set up an Apple Automator program that lets me put in a value that gets entered on line 33, but I'm fine with just an alias for now.
I know I asked this question a long time ago, but in the meantime I found a solution and forgot I had posted this question.
My alias in my .zshrc-file looks like this:
alias changeCust='ssh -t root#192.168.56.101 "nano +32 /etc/apache2/sites-enabled/25-av_miniportal.conf && service apache2 reload"'
In other words, it SSHs into vagrant as root (it asks for my password), nanos into a file on line 32 (or whatever line you need), then, when the file is saved, it reloads apache2 and the changes are applied.
Just use the below one and change the values.
alias AliasName='ssh -t root#your.ip.addres.here "nano +lineNumber /path/to/file"'
i just installed mongopi from https://github.com/RickP/mongopi and it working correctly after doing a few adjustments mainly $ sudo chown $USER /data/db. However my mongo and mongod calls arent persistent i do PATH=$PATH:/opt/mongo/bin/ &
export PATH however this does not last on next ssh session. Also how can I make mongo initialize at startup? I did all the steps from the github repo.
For the path part of the question:
To get the path working you should put it in a script that runs every time you log in. Generally there is a rc-file for you shell in your home directory. Type
echo $SHELL
to see what shell you are running. Go to your home directory:
cd
and then open the file that is called .(your shell)rc - that is, if you are running bash, open .bashrc
nano .bashrc
add the path at the end of this file:
PATH=$PATH:/opt/mongo/bin
export PATH
For the initialization part of the question:
Download and edit this script: Mongo init.d at github
You'll need to change the value of the DEAMON at line 50. I had some other troubles, but you should probably be ok if you create a configuration file (that probably could be empty) and refer to it from line 57. Also, you need to add a mongodb user that the server should run as. You can edit this on line 95, but the default is probably a good idea.
When all this editing is done, you move the file to /etc/init.d/mongodb, like so:
sudo mv init.d /etc/init.d/mongodb
and then add it to the systems start-up routine
sudo update-rc.d mongodb defaults
(This is presuming you run debian. Other distros may have other commands to do this.)
Now, see to that you are not running mongod some other place, and control the service by
sudo service mongodb start
service mongodb status
sudo service mongodb stop
... and so on. This will also run automatically on start-up and shutdown.
I have installed ActivePerl 5.14.2 on a Windows 32 bit machine running XP. My problem is that I'm trying to install a few modules with PPM and it's not working out.
According to ActiveState's website, all you need to do to install a module from their repository is "ppm install module name" , example: http://code.activestate.com/ppm/Template-Toolkit/
Every time I try this or any other module I get: "No Perl script found in input"
Even when I do just "ppm" I get the same message, even though the GUI should run.
When I run PPM with a GUI from the start menu I get this error: "Failed 500 Can't connect to ppm4.activestate.com:8080 (connect: timeout)”
I though that it might be my connection, so using cmd.exe I used the set HTTP_PROXY command and then tried ppm install, but still no luck. So is there any way I can get these modules installed?
Any advice is appreciated !!
Invoke the cpan prompt from your command prompt. Go to cmd and simply type cpan. If you successfully enter cpan prompt them there is probably no issues with your Perl installation. To install a module from cpan prompt just use
cpan>install Module::Name
Screenshot below shows command to install module Net::Stomp
If the above does not work, check if your FTP data and connection ports needs to be added to the Windows firewall exceptions (Ports 20 (FTP Command port) and 21 (FTP Data port)).
Alternatively (if you don't want to add port 20 21 to exception), you can go to the cpan prompt and use an ftp_proxy by
cpan> o conf ftp_proxy http://your.ftpproxy.com
and then issue install command. Or you can update your ../CPAN/config.pm file to make permanent changes to the ftp_proxy parameter.
The next step would be to try set the FTP_PASSIVE mode to 1. By default the libnetcfg configuration for this is set to 0. To change this find libnetcfg.bat file (should be somewhere C:\Perl\bin), open the file in an editor and replace
ftp_int_passive 0
to
ftp_int_passive 1
Again, looking at you r timeout error it seems that your network is blocking you from accessing the CPAN ftp mirrors, this would happen mostly if you are inside a corporate VPN. The solution to this can only be proxy servers.
