So when I create a debian package, I am able to write a post-installation shell script that runs just fine. Currently mine is configured to do
echo "Please enter your MySQL Database user (default root)"
read MYSQL_USER
echo "Please enter the MySQL Database user password (default root)"
read -s MYSQL_PASS
DBEXIST=0
CMD="create database lportal;use lportal;"
(mysql -u$MYSQL_USER -p$MYSQL_PASS -e "$CMD") || ((DBEXIST++))
if [ $DBEXIST -ne 0 ]; then
echo "Setup finished, but MySQL already has an lportal table. This could be from a previous installation of Liferay. If you want a fresh installation of this bundle, please remove the lportal table and reinstall this package."
fi
This works fine for Ubuntu. However, I can't seem to get user input to work with RPMs for Fedora. Is there a good way to take user input? From what I understand, RPMs were designed not to allow interactive installs. However I can't see a better way to do this..
Is there possibly a way to automatically find local MySQL settings without asking the user? Otherwise, what's the best way to ask for user input?
Okay I've resolved this without a real answer -- basically from what I understand, I have two options -- one is a wrapper script like Bind or CUPS uses. It's not considered good packaging practice though, and I'm still unsure how to go about doing it. Better is just to assign default values in the %POST script, and create a firstrun flag. The first time the user launches the software, it prompts for configuration settings.

We use chef to provision our boxes but most of our deployments are onto windows, as such infrastructure for our linux boxes isn't all there; because of this I can't log on using my own user/password.
The mechanisms for allowing login only work on windows (it's just not a priority for doing it on linux at the moment) and we only have root passwords and I don't have access to that (rightfully so).
However I could create a user during the chef run, I've looked but to be honest they're all kinda confusing, so I thought I'd ask and hope someone with experience might have a better solution.
How do I create a user with admin access so I can ssh in and do what needs to be done on the box via chef?
Best guidance I can give:
Use the user resource to create the user and then the sudo cookbook to add this user to the sudoers list.
User resource documentation
A stackoverflow question on the password attribute
Sudo cookbook
So you should end up with a cookbook containing the following:
metadata.rb
[...] # stripped usual lines for cookbook name version
depends 'sudo' # add the dependency to use only one cookbook
attributes/default.rb:
default['user_to_create'] = "user3536548" # took you SO account here
default['authorization']['sudo']['users'] << node['user_to_create'] # Add the defined user in the array (using attribute to avoid duplication of user name), this avoid overwriting entries from other recipes and as the attribute is initialized as an empty array it will be ok anyway.
recipes/default.rb
user node['user_to_create'] # create the user, see the doc for details
include_recipe 'sudo' # include the sudo recipe to take advantages of the atrtibutes above.
I've been following along with the actual MongoDB docs here
as well as several tutorial articles that are getting me absolutely nowhere.
Running a 64bit windows OS (which is a work computer, and my particular windows login is not an administrator login.. so I make sure to open any exe files as administrator). I can't do anything in the terminal beyond "mongo" or "use [db name]".
I cannot save or add anything like db.testData.insert( j ). Even typing "show dbs", I get an error that says
listDatabases failed:{ "ok" :0, "errmsg" : "unauthorized" } at src/mongo/shell/mongo.js:46
With every example I've followed, I can never seem to be "authenticated" to get past point A. Please help me! I have no idea what I'm doing wrong at this point.
UPDATE:
Sorry for the confusion, everyone. The problem turned out to be that I had an old MongoDB service still running in the background that I needed to disable.
The service must have been turned on while I was testing out some node packages or something. Once I disabled the service, everything started working as expected.
So for those of you who are having trouble, make sure you open up services.msc and make sure nothing is running MongoDB
As there isn't a formal installer for Windows, I'd recommend you delete the data folder and restart. Out of the box, there is no security in MongoDb, so you've followed a step which later requires a password. Either retrace your steps, or start over.
You don't need to switch to the admin Database. I'd suggest you instead switch to a test database for example:
> use test
switched to db test
By default, without extra configuration, on Windows you can delete the contents of c:\data\db when MongoDb isn't running (but if you're using a configuration file that specifies the dbpath, delete the contents of that folder).
There are a number of tutorials with details of how to configure users/security with Mongodb that you may want to read after you've resolved this issue.
There's little reason to create users and administrative control with MongoDB until you gain some experience with the platform. In fact, I wouldn't recommend it at all. It just gets in the way as you're seeing for no real gain.
I am currently in the process of implementing a backup scheme to run a Cygwin Expect Script. What I would like to do is have task scheduler open Cygwin and run an expect script called Backups.
The issue that I run into is what I believe to be either variable or path based. I have the correct user from Active directory (we'll call it AD/svc_backup) set, and I am currently trying to just see if I can get the task scheduler to open Cygwin.
So far it will only open the program if I have the run only when user is logged on radio button pressed. This will open cygwin, but not let me run any further commands and gives me an error.
For example ls gives me "bash: ls: command not found" When it asks what program I want to start, I simply point it to the shortcut on my desktop and it then fills in the path C:\cygwin\bin\mintty.exe . Task scheduler does not seem like the most intuitive tool IMO but if I can get it to work I will use it. I also know that cygwin can use cron as well. Would cron be a better option?
I figured it out. So what the system means by the button "run only when user is logged on" radio button pressed" means is I want the script to run and I want to see it run with the local usr account. (interactive with the user)
The "run whether the user is logged in or not" button turns whatever script or program you run into a background service that has no user interactivity( you cant see it). By using the full path under the actions tab in cygwin I was able to tell it which script to run. Script path and options are like so:
C:\cygwin\bin\bash.exe -l -c C:/cygwin/home/svc_p_cisco_bkp/
I have been researching the -l and -c arguments and from what I can gather the -l means list the output and the -c means run these commands. This was not listed anywhere but from what I read it is as educated of an answer as I can give. Also I tested and the script will not run correctly without these variables.
I don't see the script start when I check the "run whether the user is logged in or not" button, but I can see the backups going to my destination folder. I do see it when "run only when user is logged on" however. What I did was get the script running the way I wanted while I could see it and then choose the "run whether the user is logged in or not" radio button when I know it was working correctly.
All is up and running and after exhausting reading of pages and pages about Windows task scheduler, and I am fully automated.
I'm struggling with the following error when starting up sqlplus as my regular user - say "scott".
$ sqlplus
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
Environment is:
Oracle 11.2.0.2
OpenSuse Linux 11.1 (64bit)
Misc other detail:
Oracle installed and running on localhost
No tnsnames issues as can run sqlplus as oracle admin user
Database up and listener started (11.2.0.2 install).
user scott in database admin group (/etc/group)
user scott references correct 11.2.0.2 installation
This is most bizarre as I can happily run sqlplus as the oracle user (say "oraadmin") and user scott is registered in the oracle admin group. Additionally, I had no such problems with my previous Oracle install (10.2.0.7). My ~scott's $ORACLE_HOME references the 11.2.0.2 installation.
Comparing my 11.2.0.2 and 10.2.0.7 environments, I've noticed several libraries (including $ORACLE_HOME/lib/libsqlplus.so) have group read-only permissions (744) so have chmod'ded these.
Other than that, my $ORACLE_HOME/lib, $ORACLE_HOME/bin, $ORACLE_HOME/oracore and $ORACLE_HOME/rdbms all seem reasonable with sensible permissons.
N.B: There's a plethora of stuff on-line but, as is often the case, there's a lot of case-specific issues and mainly around different versions of Windows. Focusing mainly on comparing my envs. Besides, as far as I can tell, this question doesn't yet exist on SO so could be useful to start collating answers by environment. I'll report back any sensible findings.
If it is Windows 7, You can right click on SQL Plus or whatever software you using, I use Crystal Reports.
so to you would have to right click and Run as Administrator.
it fixed for me.
Fixed my particular issue...
User scott's $PATH still contained the ora11.1.0.7 bin. So, on starting sqlplus, I was running the ora11.1.0.7 sqlplus client against the 11.2.0.2 server. Think there may be more to it than that (i.e. I'd probably expect that client to work with that server) but that is the hub of the problem.
In my defence, my.bashrc sets the $PATH correctly so not yet sure what preempts it with the 11.1.0.7 version. Guess the sensible rule of thumb is to add my $ORACLE_HOME/bin to the front of the $PATH to ensure mine is found first, despite what else is set by whatever other environment config, as in
export PATH=$ORACLE_HOME/bin:$PATH
Yours, a little embarrassed but hopefully will be of help again to someone.

In Windows i found the solution ---
Assign the "Create global objects" user right to the non-Administrator account.
Go to Administrative Tools, and then click Local Security Policy.
Expand Local Policies, and then click User Rights Assignment.
In the right pane, double-click Create global objects.
In the Local Security Policy Setting dialog box, click Add.
In the Select Users or Group dialog box, click the user account that you want to add, click Add, and then click OK.
Click OK.
Maybe that's more of a Linux question than an Adobe Air one, but there you go: I have an AIR 2 app that does auto-update in the background, with no need for user interaction. It uses Air's own ApplicationUpdater framework (the one that doesn't require a UI) - all goes well until the package gets downloaded and needs to be installed - at that point, the Air Installer prompts for SUDO password and won't proceed without some user interaction.
Is there any way to circumvent/avoid that?
I solved this by adding a rule to the sudoers file (/etc/sudoers)
<username> ALL=(root) NOPASSWD: /tmp/air.*/setup
This rule can enable the update to all users
ALL ALL=(root) NOPASSWD: /tmp/air.*/setup
Note that it could lead to some security issues but I think if you are going to use this as a Linux Kiosk it's going to work.
You could do that by rolling your own updating mechanism. Is not really that difficult, if you plan it correctly you don't even need to close the app.
We did so for an internal project, where we use git. Since I guess you can't rely on Git being available on the user's machine, you could check out the server, download a zip file, uncompress it and replace the contents of your app.
AIR doesn't sign or checksum the files it installs, you can safely replace them and re-load the app without problems.
HTH,
