I have tomcat9 on linux as an on demand service, go into /bin and start. I have a simple setenv.sh, shown below, that now fails show second below. Everything is standard no other changes. TC does startup how I need those options working. How could this have gone from working to non-working. How can I get again working and loading the setenv.sh?
setenv.sh: CATALINA_OPTS=-Xmx512m -Djasypt.encryptor.password=123
on startup or shutdown this first message. of course catalina.sh is in the executing directory.
./catalina.sh: 1: /usr/tomcat/tc9/bin/setenv.sh:
-Djasypt.encryptor.password=123: not found

I have a simple python3 script running on ubuntu server 20.04 that tries to call clamd (clamav-daemon process) library to scan a file. The scan ping() and version() function all work correctly. However when I actually do a test write and scan, i get the following error:
{'/filedrop/test.doc': ('ERROR', "Can't open file or directory")}
This is the code that I used to call the test write and scan, and this is all standard sample from the clamd website:
open('/filedrop/test.doc','wb').write(clamd.EICAR)
print(cd.scan('/filedrop/test.doc'))
After the code is run, i get the following string in the test file which indicates that the python3 script was able to successfully write to the file, yet i keep getting the error that the file can't be opened when i use the clamd scan function.
This is the string that was written to the file:
X5O!P%#AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
I am also able to run clamscan from command line on the folder and it successfully scans the files as well.
I'm running as root user while the service is using clamav:clamav.
I did give read/write permission to the folder and the files to "other users", and also indicated by the fact that the file could be written by the python script.
I believe the solution to the problem here is that AppArmour is blocking clamd for that particular directory. I would look at the AppArmour profile for clamd. It should be called something like /etc/apparmor.d/clamav or similar. You can adjust that profile or alternatively disable it (according to Ubuntu):
sudo ln -s /etc/apparmor.d/profile.name /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/profile.name
More complete instructions available here:
https://help.ubuntu.com/community/AppArmor
You can also disable AppArmour, for the purposes of testing (I don't like to advise anyone to remove security features permanently), with:
sudo systemctl stop apparmor
sudo systemctl disable apparmor
I am working with Ubuntu 16.04 and I have two shell scripts:
run_roscore.sh : This one fires up a roscore in one terminal.
run_detection_node.sh : This one starts an object detection node in another terminal and should start up once run_roscore.sh has initialized the roscore.
I need both the scripts to execute as soon as the system boots up.
I made both scripts executable and then added the following command to cron:
#reboot /path/to/run_roscore.sh; /path/to/run_detection_node.sh, but it is not running.
I have also tried adding both scripts to the Startup Applications using this command for roscore: sh /path/to/run_roscore.sh and following command for detection node: sh /path/to/run_detection_node.sh. And it still does not work.
How do I get these scripts to run?
EDIT: I used the following command to see the system log for the CRON process: grep CRON /var/log/syslog and got the following output:
CRON[570]: (CRON) info (No MTA installed, discarding output).
So I installed MTA and then systemlog shows:
CRON[597]: (nvidia) CMD (/path/to/run_roscore.sh; /path/to/run_detection_node.sh)
I am still not able to see the output (which is supposed to be a camera stream with detections, as I see it when I run the scripts directly in a terminal). How should I proceed?
Since I got this working eventually, I am gonna answer my own question here.
I did the following steps to get the script running from startup:
Changed the type of the script from shell to bash (extension .bash).
Changed the shebang statement to be #!/bin/bash.
In Startup Applications, give the command bash path/to/script to run the script.
Basically when I changed the shell type from sh to bash, the script starts running as soon as the system boots up.
Note, in case this helps someone: My intention to have run_roscore.bash as a separate script was to run roscore as a background process. One can run it directly from a single script (which is also running the detection node) by having roscore& as a command before the rosnode starts. This command will fire up the master as a background process and leave the same terminal open for following commands to be executed.
If you could install immortal you could use the require option to start in sequence your services, for example, this is could be the run config for /etc/immortal/script1.yml:
cmd: /path/to/script1
log:
file: /var/log/script1.log
wait: 1
require:
- script2
And for /etc/immortal/script2.yml
cmd: /path/to/script2
log:
file: /var/log/script2.log
What this will do it will try to start both scripts on boot time, the first one script1 will wait 1 second before starting and also wait for script2 to be up and running, see more about the wait and require option here: https://immortal.run/post/immortal/
Based on your operating system you will need to configure/setup immortaldir, her is how to do it for Linux: https://immortal.run/post/how-to-install/
Going more deep in the topic of supervisors there are more alternatives here you could find some: https://en.wikipedia.org/wiki/Process_supervision
If you want to make sure that "Roscore" (whatever it is) gets started when your Ubuntu starts up then you should start it as a service (not via cron).
See this question/answer.
I am working on a BBB device running on an Angstrom image and the display panel is a 7 inch LCD cape. I want to start an application as soon as log-in message prompts means the application should get start automatically just after the booting. To achieve this I tried
1) To put my script files in /etc/init.d and linked the script with /etc/rc5.d as S99myscript and then updated the rc.d
But it was not an successful attempt.
2) I changed the /etc/issue file a little bit and to invoke the script i appended myscript file in the last as this.
. /home/root/myscript
// tried it like this also
sh . /home/root/myscript
but this time also i couldn't get my desired result.
What's i am missing ? Or how can I get the result.
The service file
Status of service file
I'm just getting started with Yii2 and I am following a tutorial here about setting up Yii2/AdminLTE and I am unable to finish the setup as I am getting errors in Terminal on the last step.
The part I am not able to finish is:
finaly we create rbac dbmanager with simple code, you can see in
folder "console/RbacController" with specific level for :
Admin : can do everything Editor : can edit, add and view Author : can
add and view viewer ; just viewer create rbac :
"yii migrate --migrationPath=#yii/rbac/migrations"
"yii rbac/init"
dont forget to chmod -R 777 on your web/assets if linux environment
and please free to update your setting on menu setting.
So in terminal on my mac, I tried both:
yii migrate --migrationPath=#yii/rbac/migrations
with the error: -bash: yii: command not found
and
/.yii migrate --migrationPath=#yii/rbac/migrations
with error: -bash: /.yii: No such file or directory.
I was able to complete the beginning of the tutorial, it is just this last step. I am already working in my yii2-advanced-adminlte directory
UPDATED:
Added screenshot of terminal window
Normally the yii command is located in
fro advanced template in project directory parent of backend, frontend, console and not in console
be sure of find the right dir and then accessing this try launche your command
yii migrate --migrationPath=#yii/rbac/migrations
eventually adjust your path to rbac/ migrations
Found it out, the problem was using MAMP I had to manually set the php bin to 5.5.23 in terminal because once I started down the path scaisEdge showed me I was getting a No such File or Folder error.
Eventually this is the command that worked for me (check your php MAMP path):
/Applications/MAMP/bin/php/php5.5.23/bin/php yii migrate

I have a web role that I'm trying to run locally using the emulator. I have it working on another computer, but I cannot get it working on a different one, and have gone as far as to reformat it and start from scratch.
When I launch the site from Visual Studio, Chrome shows the following message:
This webpage is not available
The connection to 127.0.0.1 was interrupted.
There is also an error code listed at the bottom:
Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.
One interesting thing from the build output are these lines:
Starting process 'C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\Windows Azure Tools\v1.8\Debugger\WindowsAzureDebugger.exe' with arguments '"C:\Program Files\IIS Express\iisexpress.exe" /trace:error /config:"C:\Users\brian\AppData\Local\dftmp\Resources\159c7254-b7d0-4076-a4fd-820b00feca5f\temp\temp\RoleTemp\applicationHost.config" /site:"deployment18(27).AzureApp.MyApp.Web_IN_0_Web"'...
Process 'C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\Windows Azure Tools\v1.8\Debugger\WindowsAzureDebugger.exe' exited with exit code 0.
If I run C:\Program Files\IIS Express\iisexpress.exe" /trace:error /config:"C:\Users\brian\AppData\Local\dftmp\Resources\159c7254-b7d0-4076-a4fd-820b00feca5f\temp\temp\RoleTemp\applicationHost.config" /site:"deployment18(27).AzureApp.MyApp.Web_IN_0_Web" from the command line, I get the following message:
The system cannot find the file specified.
Unable to start IIS Express in background.
I have no idea what file it cannot find, but I've verified that the config file I'm passing does in fact exist. Anyone have a clue what's going on here??
While I can not tell you what could be the actual root cause of your problem I can suggest a few ways to troubleshoot it:
Try changing IIS Express to Full IIS and see if it changes the behavior. You can do it by going to your Windows Azure Application project properties and look at "Web" option.
Try running application without debugging it
Launch CSrun at command prompt with /launchDebugger parameter of the /run option to verify that debugger does run without any issue
Try using IE as default browser
Clean your dftemp folder completely for any residual configuration and then launch Azure Emulator separately to verify there are no issues
Procmon "http://technet.microsoft.com/en-us/sysinternals/bb896645" may help you find the file that is missing...
Hopefully someone stumbles upon this answer with similar symptoms. When removing in role caching the <dataCacheClients> section was removed from . Somehow there was a left over <dataCacheClients> section left in the web.config. Everything and compiled and deployed to the emulator successfully. However, the role would fail to start since applicationHost.config was missing.
The fix was simply remove the unnecessary <dataCacheClients> section from the web.config file.
