I am following this tutorial (Hosting Nancy with Nginx on Ubuntu) with one change. I am using the Spark view engine instead of the built in view engine.
Spark view engine throws an error building any view when the Nancy host is running under supervisor.
System.SystemException: Error running mcs: Cannot find the specified file

If I run the environment setting script /opt/mono/env.sh and then run my host from the command prompt, the website works.
I think it must be due to my Nancy host not being able to find Mono when running under supervisor.
For reference:
#env.sh
export PATH=/opt/mono/bin:$PATH
export LD_LIBRARY_PATH=/opt/mono/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=/opt/mono/lib/pkgconfig:$PKG_CONFIG_PATH
I am using Mono 3.8.0 from here:
http://download.opensuse.org/repositories/home:/tpokorra:/mono/xUbuntu_14.04/
How do I set these paths so that Nancy host can find Mono when running under supervisor?
I needed to set the environment option in my supervisor configuration file.
Here is the setting that worked for the above example.
environment=PATH="/opt/mono/bin:$PATH"

Shopware version: 6.4.12.0
I want to build the administration via the ./bin/build-administration.sh command. On my local setup it works great in the docker container but if I want to build it on the server the build hangs forever on this message:
Calling reporter service for single check.
I already tried to set this in the ./bin/build-administration.sh:
export DISABLE_ADMIN_COMPILATION_TYPECHECK=1
but then it after the injection of the plugins.
Any idea's? Thanks!
Q1. What versions are we using?
Ans.
Python 3.6.12
OS : CentOS 7 64-bit
DB : Oracle 18c
Django 2.2
cx_Oracle : 8.1.0
Q2. Describe the problem
Ans. While running server with "python3 manage.py runserver"
application is able to contact Oracle DB and show the Django Administration page and login also works.
But when we access the application using the Apache (HTTPD) based URL over secure SSL port, we do see the Django page and the admin page as well but Login to Admin page with Internal server error.
In the logs, we see
"django.db.utils.DatabaseError: Error while trying to retrieve text for error ORA-01804"
cx_oracle is otherwise able to connect to the database properly, another application is also using the same database behind the same httpd proxy and works fine
Q3. Show the directory listing where your Oracle Client libraries are installed (e.g. the Instant Client directory). Is it 64-bit or 32-bit?
Ans. 64-bit
Q4. Show what the PATH environment variable (on Windows) or LD_LIBRARY_PATH (on Linux) is set to?
LD_LIBRARY_PATH=/srv/vol/db/oracle/product/18.0.0/dbhome_1/lib:/lib:/usr/lib
PATH=$ORACLE_HOME/bin:/srv/vol/db/oracle/product/18.0.0/dbhome_1/lib:$PATH
Q5. Show any Oracle environment variables set (e.g. ORACLE_HOME, ORACLE_BASE).
ORACLE_HOME=/srv/vol/db/oracle/product/18.0.0/dbhome_1
TNS_ADMIN=$ORACLE_HOME/network/admin
NLS_LANG=AMERICAN_AMERICA.AL32UTF8
ORACLE_BASE=/srv/vol/db/oracle
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/lib
Any suggestions/help is highly appreciated.
Thank you
I found the problem
So I just removed all the variable declarations from /etc/sysconfig/httpd and checked, the application was still able to access the lib files, so these were now redundant.
Then undid all variable declarations done earlier in .localsh and .localrc files for the os users. To start from scratch, and go step by step to see where it breaks.
So now, cx_Oracle was looking for the lib files in wrong directory
$ORACLE_HOME/client_1/lib
instead of
$ORACLE_HOME/lib
DPI-1047: Cannot locate a 64-bit Oracle Client library: "$ORACLE_HOME/client_1/lib/libclntsh.so: cannot open shared object file: No such file or directory". See https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html for help
I did not have any subfolder named "client_1" inside dbhome_1
so I just created a symlink client_1 that points to dbhome_1 (still unsure on this, but at least it works :) )
So, now, this error was gone but now again ORA-01804 was coming. 😑
I had read somewhere that this error can be fixed by adding "libociei.so" but I did not have one on my instance, so I generated it using these commands:-
mkdir -p $ORACLE_HOME/rdbms/install/instantclient/light
cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk igenliboci
Then I just moved this libociei.so file from
$ORACLE_HOME/instantclient to $ORACLE_HOME/lib
Now there was a new error (so.. progress 😉 ):
ORA-12546 - TNS Permission Denied.
This was easy to solve 😀
I used this command to address this :-
setsebool -P httpd_can_network_connect on
And...... That was all! It worked.
Question - Is there a better/right way to get the application's launch path?
Setup -
I have a console application that runs in a Linux Debian docker image. I am building the application using the --runtime linux-x64 command line switch and have all the runtime identifiers set appropriately. I was expecting the application to behave the same whether launching it by calling dotnet MyApplication.dll or ./MyApplication but they are not.
Culprit Code -
I have deployed files in a folder below the application directory that I reference so I do the following to get what I consider my launch path. I have read various articles saying this is the correct way to get what I want, and it works depending on how I launch it.
using var processModule = Process.GetCurrentProcess().MainModule;
var basePath = Path.GetDirectoryName(processModule?.FileName);
When launching this using the comand dotnet MyApplication.dll the above codes path is /usr/share/dotnet
When launching this using the command ./MyApplication.dll the path is then /app
I understand why using dotnet would be different as it is the process that is running my code, but again it was unexpected.
Any help here to what I should use given the current environment would be appreciated. Ultimately I need the path where the console application started from as gathered by the application when it starts up.
Thanks for your help.
This code should work:
public static IConfiguration LoadConfiguration()
{
var assemblyDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
.....
}
Under Ubuntu environment, NodeJS Google Vision complains:
Error: Unable to detect a Project Id in the current environment.
Even though I already put json credential through
$ export GOOGLE_APPLICATION_CREDENTIALS=/var/credential_google.json"
Please help.
As a quick hack you can try this :
$ GOOGLE_APPLICATION_CREDENTIALS="/var/credential_google.json" node app.js
It's not recommended to use a .json config file locally. I've seen these leak on production servers causing whole platforms to be deleted + the introduce environmental switching and security issues.
Setup Google Cloud CLI.
Now the server will 'look' at the local environment and use that.
If you get the error "Unable to detect a Project Id in the current environment.", it means the auth library cannot find the project default id.
You need to have a base project in Google Cloud set, regardless of environmental variables and project you're running.
Run
gcloud config set project [some-project-id]
Now if you run (node example)
"dev": "NODE_ENV=dev GCP_PROJECT=some-project-id nodemon index.ts",
It will load the project environment. This also allows you to deploy easier with:
"deploy:dev": "y | gcloud app deploy --project some-dev-project app.yaml",
"deploy:prod": "y | gcloud app deploy --project some-prod-project app.yaml"
App engine has security setup automatically with standard environments. With flex you can use one of the manage images Google Provides.
If you are usually a windows user and trying out Ubuntu (like me), the problem is likely with the assumptions that the export command exports variable to all terminal sessions and that you need to open a new terminal to get it to use (as expected in a windows terminal for an environment variable).
The export command doesn't export the variable to another terminal session. So if you export it in a terminal, you use it on the same terminal.
If you would like to export it permanently, then you can try the solution listed here
You can put the path to the JSON credentials directly when instantiating the client, by passing it as an argument.
For example:
const client = new speech.SpeechClient( {keyFilename: "credential_google.json"});
Also, for me setting it in the terminal didn't work.
I am trying to setup ELK stack for my Web Services Log Monitoring.
So I have setup all the parts for ELK Stack.
I am facing one issue in Log-stash. When I am running Log-stash, I am facing error, could not load Java binary
Although the simple fix it set the JAVA_HOME in environment variable.
But I don't want to set an environment variable, but what I want to set JAVA_HOME just for Log-stash. I have tried adding in startup.options, but to enable I must run system-install. When I am running system-install, I am facing the same error again.
I have added
export JAVA_HOME=/opt/jre8
then system-install file runs, but still on starting log-stash, I am getting the same error. What should I do to resolve this error?
You can config in startup.options (logstash5.4 version):
Ex:
JAVA_HOME=/.../jdk1.8.0_121
JAVACMD=/.../jdk1.8.0_121/bin/java
Then use root role to start: system-install.
(You can use update-java-alternatives --list to list installed java versions with paths)
You can add this configuration to the file- /etc/sysconfig/logstash, this file is read during startup by logstash.
This is what you should add:
export JAVA_HOME=/opt/jre8
