How to reconfigure zabbix-server? - zabbix

I have installed the ZABBIX from the sources, I need to be recompiling to add the --enable-java option.
Then I executed ./configure and make,but I don't known which executable file should be replaced in the installation directory,
I search the zabbix_server file in the unzip directory,
[root#zbx-flm zabbix-3.2.1]# find . -name zabbix_server -type f
./misc/init.d/freebsd/zabbix_server
./misc/init.d/fedora/core/zabbix_server
./misc/init.d/fedora/core5/zabbix_server
./misc/init.d/tru64/zabbix_server
./misc/init.d/suse/9.1/zabbix_server
./misc/init.d/suse/9.3/zabbix_server
./misc/init.d/suse/9.2/zabbix_server
These are just the startup files, not the binary files。So what should I do?

If these are unmodified sources and the compilation was successful, the server binary will be in the src/zabbix_server subdirectory.
Please note that the --enable-java flag does not modify the Zabbix server binary. Instead, Java gateway is built in src/zabbix_java. That is not a single binary anymore, though.

Problem with the command-line JSON processor JQ in Windows 10, 64 bit

I have downloaded the program jq-win64.exe from 'https://stedolan.github.io/jq/' and installed the program in a folder C:\Program Files\jq\ on my computer.
I have also added the PATH to the program to the end of the systemvariable string in Windows 10 : . . . ;C:\Program Files\curl\;C:\Program Files\jq\
In one terminal window in Visual Studio Code I am running a server.
In another terminal window I am trying to execute the command curl -s localhost:3000 | jq
Terminal window 1:
C:\Users\SteinarV\PROFF_JAVASCRIPT\PROJECT\smartHouse
node server.js
API running on port 3000
Terminal window 2:
C:\Users\SteinarV\PROFF_JAVASCRIPT\PROJECT\smartHouse>curl -s localhost:3000 | jq
'jq' is not recognized as an internal or external command,
operable program or batch file
... and do not understand why jq is not recognized.
Can someone help ?
I have downloaded the program jq-win64.exe from 'https://stedolan.github.io/jq/' and installed the program in a folder C:\Program Files\jq\ on my computer.
As you have indicated, you have a file called jq-win64.exe but you are trying to execute the command jq. You either need to rename the file to jq.exe or you need to use the command jq-win64.
For a detailed explanation of how Windows finds and executes a program in your path when you enter a command, see The Windows NT Command Shell: Command Search Sequence. Specifically:
...The shell now searches each directory specified by the PATH environment variable, in the order listed, for an executable file matching the command name. If a match is found, the external command (the executable file) executes...
...If the command name does not include a file extension, the shell adds the extensions listed in the PATHEXT environment variable, one by one, and searches the directory for that file name. Note that the shell tries all possible file extensions in a specific directory before moving on to search the next directory (if there is one)...
You indicate in the comments the same error persists even when the filenames match. Note that each running program has its own set of environment variables, and these aren't updated by global changes. You need to close and reopen cmd.exe windows after making a global change. See also Adding directory to path environment variable in windows. You can use the path command to verify whether a particular terminal session has inherited the PATH variable you defined, thus narrowing your problem.
You indicate that the problem still persists. You need to use the tools available to you to narrow it down further:
Try running the program with its full path:
"C:\Program Files\jq\jq-win64.exe" --help
This will confirm that the program is present where you think it is and can be run from the terminal.
Try running the program with no path and its extension:
jq-win64.exe --help
If this works but running the program without an extension doesn't, you might have set PATHEXT to something that doesn't include ".EXE".
Try setting the path explicitly in the terminal to contain only the program directory and nothing else, then run it with its full extension:
set PATH=C:\Program Files\jq
jq-win64.exe --help
(Note that after this test you'll need to close the terminal window and start a new one to reset the path.)
If this works, perhaps you have a mismatch in your path.

phoenix through upload bulk csv file command not understand?

I want to upload bulk csv file using phonix but I can not understood below command. Can you explain me in details ?
HADOOP_CLASSPATH=$(hbase mapredcp):/path/to/hbase/conf hadoop jar phoenix-<version>-client.jar org.apache.phoenix.mapreduce.CsvBulkLoadTool --table EXAMPLE --input /data/example.csv
I take this command from following website.
https://phoenix.apache.org/bulk_dataload.html
I am not sure if you are still looking for an answer. But here it is. You are first setting the HADOOP_CLASSPATH and then call the executable "hadoop" with jar options to look for phoenix client jar and the class to run with parameters.
The following can help you to understand hadoop command usage (try typing hadoop on your ssh shell)
Usage: hadoop [--config confdir] [COMMAND | CLASSNAME]
CLASSNAME run the class named CLASSNAME
or
where COMMAND is one of:
fs run a generic filesystem user client
version print the version
jar <jar> run a jar file
note: please use "yarn jar" to launch
YARN applications, not this command.
checknative [-a|-h] check native hadoop and compression libraries availability
distcp <srcurl> <desturl> copy file or directories recursively
envvars display computed Hadoop environment variables
archive -archiveName NAME -p <parent path> <src>* <dest> create a hadoop archive
classpath prints the class path needed to get the
credential interact with credential providers
Hadoop jar and the required libraries
daemonlog get/set the log level for each daemon
trace view and modify Hadoop tracing settings
Most commands print help when invoked w/o parameters.

Azure AppService deploy.cmd using the wrong file

I am trying to configure continuous deployment to a test server on Azure. The app is an ASP.Net application, but in this case that shouldn't really matter.
My build process (team city) produces a folder that has everything needed to deploy (minus some connection string info). If you point IIS at that directory it works great. If you FTP that directory up to Azure it also works.
I am tracking each of these builds in git and pushing them up to Github. So I am trying to use Azure deployment option to deploy from github. Everything is in git. The /bin folder included.
Kudu shouldn't need to do anything but a pull from git and copy all the files to wwwroot.
So I've set my .deployment file to be this:
[config]
project = .
Every time I do that, though, the deployment gives me the message:
Using cached version of deployment script (command: 'azure -y --no-dot-deployment -r "D:\home\site\repository" -o "D:\home\site\deployments\tools" --aspWAP "D:\home\site\repository\MyProj.csproj" --no-solution').
And it runs some generic autogenerated deploy.cmd.
If I delete the deploy.cmd from the cache, it regenerates some generic one.
And, most importantly, in doing all this, the WRONG ASSEMBLY IS BEING DEPLOYED!!
My app depends on System.Web.Helpers.dll. The correct version of this DLL is in github. I've verified this multiple times.
Kudu, however, is grabbing an OLDER one from NuGet and deploying that. And, of course, I get the dreaded YSOD error about not being able to load that file.
What do I need to do to make Kudu just copy the files from my github repository to wwwroot and nothing else?
I wound up getting it to deploy by hand editing the autogenerated deploy.cmd file that lives at \home\site\deployments\tools\deploy.cmd in kudu.
I commented out the 2 autogenerated lines of:
:: 1. Restore NuGet packages
:: 2. Build to the temporary path
(commented out all the code underneath them, too)
And then hand-edited the 3rd section to run kudu sync from the DEPLOYMENT_SOURCE instead of the temp file like this:
:: 3. KuduSync
IF /I "%IN_PLACE_DEPLOYMENT%" NEQ "1" (
call :ExecuteCmd "%KUDU_SYNC_CMD%" -v 50 -f "%DEPLOYMENT_SOURCE%" -t "%DEPLOYMENT_TARGET%" -n "%NEXT_MANIFEST_PATH%" -p "%PREVIOUS_MANIFEST_PATH%" -i ".git;.hg;.deployment;deploy.cmd"
IF !ERRORLEVEL! NEQ 0 goto error
)

How to convert bash file to a binary executable

I created a binary executable from bash script on linux server through SHC. The binary created works fine on linux machines, but through mistake on Mac. How could I convert my bash file to binary executable that is able to run everywhere(ubuntu, CentOS, Mac, Cygwin)?
shc -v -r -T -f ir16fetcher.sh
mv ir16fetcher.sh.x ir16fetcher
Shebang of my bash script
#!/bin/bash
On Linux machines
./ir16installer
USAGE : ir16fetcher <servername/ip address> [the n th latest build - optional. Default 1]
EXAMPLE: ir16fetcher jagger 2
EXAMPLE: ir16fetcher 167.116.6.155
REQUIRE: Please make sure conf file in installation folder ~/IRinstall/ir16 & ~/IRinstall/irmanager
On my Mac
./ir16installer
-bash: ./ir16installer: cannot execute binary file
I think it's not gonna work
"The compiled binary will still be dependent on the shell
specified in the first line of the shell code (i.e.
#!/bin/sh), thus shc does not create completely independent
binaries."
From http://www.datsi.fi.upm.es/~frosal/sources/shc.html
You will have to do this for every architecture and operating system you need to support. In any case, there doesn't really seem to be any benefits of using this method for distribution. It adds dependencies and complicates delivery, and I'm pretty sure whatever obfuscation the "shc" compiler implements is easily reversed.
if the goal here is to "hide" your source code, and then have the "hidden" copy of the code be executable on the Unix OSes you listed, then, encryption is really your only option.
I say this because encryption tools are available on every base Unix install. For your purposes, this is a very good thing as you wont have to download or configure anything additional. They're just there, as part of the natural installation of the OS. One of such tools is called openssl.
To Encrypt your file/script with openssl:
echo precious-content | openssl aes-128-cbc -a -salt -k mypassword
U2FsdGVkX1+K6tvItr9eEI4yC4nZPK8b6o4fc0DR/Vzh7HqpE96se8Fu/BhM314z
To Decrypt your file/script with openssl:
echo U2FsdGVkX1+K6tvItr9eEI4yC4nZPK8b6o4fc0DR/Vzh7HqpE96se8Fu/BhM314z | openssl aes-128-cbc -a -d -salt -k mypassword
precious-content
Now, to get openssl to do what you want it to do automatically without having to spend hours of your own time figuring out a way, you can paste your script to a site like www.EnScryption.com. This site will generate an "executable" version of your code for you, which you can then run on any Mac, Ubuntu, RedHat, CentOS box.

Tesseract running error

I have a problem with running tesseract-ocr engine on linux. I've downloaded RUS language data and put it to tessdata directory (/usr/local/share/tessdata). When I'm trying to run tesseract with command tesseract blob.jpg out -l rus , it displays an error:
Error opening data file /usr/local/share/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language eng
Tesseract couldn't load any languages!
Could not initialize tesseract.
According to compiling guide, I used export TESSDATA_PREFIX='/usr/local/share/'
to point my tessdata directory.
Maybe I should edit any config files? Tesseract try to load 'eng' data files instead of 'rus'.
Screenshot:
http://i.stack.imgur.com/I0Guc.png
You can grab eng.traineddata Github:
wget https://github.com/tesseract-ocr/tessdata/raw/main/eng.traineddata
Check https://github.com/tesseract-ocr/tessdata for a full list of trained language data.
When you grab the file(s), move them to the /usr/local/share/tessdata folder. Warning: some Linux distributions (such as openSUSE and Ubuntu) may be expecting it in /usr/share/tessdata instead.
# If you got the data from Google, unzip it first!
gunzip eng.traineddata.gz
# Move the data
sudo mv -v eng.traineddata /usr/local/share/tessdata/
The simpliest way is to install the needed package:
sudo apt-get install tesseract-ocr-eng #for english
sudo apt-get install tesseract-ocr-tam #for tamil
sudo apt-get install tesseract-ocr-deu #for deutsch (German)
As you can notice, it opens the road to others languages (i.e. tesseract-ocr-fra).
I had this error too on the Windows machine.
My solution.
1) Download your language files from
https://github.com/tesseract-ocr/tessdata/tree/3.04.00
For example, for eng, I downloaded all files with eng prefix.
2) Put them into tessdata directory inside of some folder. Add this folder into System Path variables as TESSDATA_PREFIX.
Result will be
System env var: TESSDATA_PREFIX=D:/Java/OCR
And OCR folder has tessdata with languages files.
This is a screenshot of the directory:
No previous solution worked for me.
I've installed both by apt-get and manually downloading the tessdata, moved around /usr and so on and no one worked even if i exported the variable thousand times.
Finally, on a last try before start to cry i've tried to pass the path directly to the instance of Tesseract().
In Python: tr = Tesseract("/usr/local/share/tesseract-ocr/") and now it works. To clarify, im using tesserwrap module.
For Windows Users:
In Environment Variables, add a new variable in system variable with name "TESSDATA_PREFIX" and value is "C:\Program Files (x86)\Tesseract-OCR\tessdata"
tesseract --tessdata-dir <tessdata-folder> <image-path> stdout --oem 2 -l <lng>
In my case, the mistakes that I've made or attempts that wasn't a success.
I cloned the github repo and copied files from there to
/usr/local/share/tessdata/
/usr/share/tesseract-ocr/tessdata/
/usr/share/tessdata/
Used TESSDATA_PREFIX with above paths
sudo apt-get install tesseract-ocr-eng
First 2 attempts did not worked because, the files from git clone did not worked for the reasons that I do not know. I am not sure why #3 attempt worked for me.
Finally,
I downloaded the eng.traindata file using wget
Copied it to some directory
Used --tessdata-dir with directory name
Take away for me is to learn the tool well & make use of it, rather than relying on package manager installation & directories
For me the problem was in how I downloaded the train data files. Make sure you get the raw link.
Initially I was using:
wget https://github.com/tesseract-ocr/tessdata_best/blob/master/eng.traineddata
When I changed it to:
wget https://github.com/tesseract-ocr/tessdata_best/raw/master/eng.traineddata
It worked
For Ubuntu just run the below command and the Environment variable error will disappear.
command:
export TESSDATA_PREFIX=Path_of_your_tessdata_folder
Command Example:
export TESSDATA_PREFIX=/home/amar/Desktop/OCR/tesseract-4.1.1/tessdata
This command will set the tessdata folder's path to the environment variable with name TESSDATA_PREFIX and the above error will be resolved.
You can call tesseract API function from C code:
#include <tesseract/baseapi.h>
#include <tesseract/ocrclass.h>; // ETEXT_DESC
using namespace tesseract;
class TessAPI : public TessBaseAPI {
public:
void PrintRects(int len);
};
...
TessAPI *api = new TessAPI();
int res = api->Init(NULL, "rus");
api->SetAccuracyVSpeed(AVS_MOST_ACCURATE);
api->SetImage(data, w0, h0, bpp, stride);
api->SetRectangle(x0,y0,w0,h0);
char *text;
ETEXT_DESC monitor;
api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
printf("m.count: %s\n", monitor.count);
printf("m.progress: %s\n", monitor.progress);
api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
...
api->End();
And build this code:
g++ -g -I. -I/usr/local/include -o _test test.cpp -ltesseract_api -lfreeimageplus
(i need FreeImage for picture loading)
I'm using windows OS, I tried all solutions above and none of them work.
Finally, I install Tesseract-OCR on D drive(Where I run my python script from) instead of C drive and it works.
So, if you are using windows, run your python script in the same drive as your Tesseract-OCR.
In Google Colab I resolved the issue in this way:
!sudo apt-get install tesseract-ocr-*
Because if you use this command !sudo apt install tesseract-ocr then it imports 2 languages but when you intend to work on non-English languages then the former command works.
Afterwards, use this command !pip install pytesseract
You can also check languages in this way !tesseract --list-langs
I'm using Visual Studio 2017 Community Edition.
I solved this problem by making a directory called tessdata in the Debug directory of my project. Then I put the eng.traineddata file into said directory.
C# developer working on Windows here. What works for me is simply download the file eng.traineddata from the following URL:
https://github.com/tesseract-ocr/tessdata/blob/master/eng.traineddata
and copy it to the following directory in my Console Application project:
[Project Directory]\bin\Debug\tessdata
I did manually create the tessdata folder above.
tessdata_dir_config = r'--tessdata-dir "/usr/local/Cellar/tesseract/4.1.1/share/tessdata"'
pytesseract.image_to_string(imgCrop,lang='eng',config=tessdata_dir_config)
Add this to your code :
instance.setDatapath("C:\\somepath\\tessdata");
instance.setLanguage("eng");
How I solved the problem in my Manjaro Xfce:
Message “TesseractError: (1, 'Error opening data file /home/julio/snap/tesseract/common/eng.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language 'eng' Tesseract couldn't load any languages! Could not initialize tesseract.')”
Then, in my Manjaro, I typed: sudo pacman -S tesseract
Then the system installed both the “tesseract” and also a package name “leptonica”
After this step, I thought everything was ok, and tried to run my simple script. However, the error message changed to something like this (it changed the previous “/home” location to other “/usr”-like location):
“"Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language 'eng' Tesseract couldn't load any languages! Could not initialize tesseract.')"”
Then I realized that there had appeared this message when I installed “tesseract” with pacman: “You must install one of tesseract-data-* packages or whole tesseract-data group”
So, I tried the command: “sudo pacman -S tesseract-data”, and the system presented lots of language options to me. So I’ve chosen some languages, installed as follows, and the module started to work like a charm:
sudo pacman -S tesseract-data-eng
sudo pacman -S tesseract-data-por
sudo pacman -S tesseract-data-fra
sudo pacman -S tesseract-data-spa
I tried some portuguese special characters (like "ão"), that only worked when I used the argument "lang='por'" in the pytesseract.image_to_string(img,lang='por')
As of 2021, My solution for Ubuntu is to download the zip files from https://github.com/tesseract-ocr/tessdata_best/releases/tag/4.1.0, extract and copy the neccessary .traineddata files into /usr/local/share/tessdata. This is the default folder for tesseract 4.1.1 to search for trained data.
I had the same problem with DEU language on macOS. I could solve it by installing all additional languages like so:
brew install tesseract-lang
as suggested on https://formulae.brew.sh/formula/tesseract
**IF you have windows OS then please add your TesseractOCR to system variable.
Eg..
Find the path where Tesseract is installed in your c drive (in my case r"C:\Program Files\Tesseract-OCR\tesseract.exe")**
2)make sure you have the required files ie tessdata, tessdata if not then download it from https://github.com/tesseract-ocr/tessdata https://github.com/tesseract-ocr/langdata (At least those languages which you want to convert)
past it into the main directory in my case C:\Program Files\Tesseract-OCR
4)Add the path of the directory to your system environment variable
for that
search environment variable in start bar
go to environment variable
click path in your system environment variable (NOT IN USER ENVIRONMENT VARIABLE)
past the path of tesseractocr
thats all...
