I recently upgraded Zabbix to 5.4.1 and I wanted to start using scheduled report, but I've got some problems with conifguration (error Cannot connect to web service: couldn't connect to server).
My Zabbix is running in Docker on Debian Buster. Everything is based on official containers:
Zabbix Server (PostgreSQL), Zabbix Frontend (Apache, PostreSQL) and PostgreSQL12.
According do documentation (https://www.zabbix.com/documentation/current/manual/appendix/install/web_service) I installed Google Chrome browser:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo apt install ./google-chrome-stable_current_amd64.deb
and Zabbix Web Service
wget https://repo.zabbix.com/zabbix/5.4/debian/pool/main/z/zabbix-release/zabbix-release_5.4-1+debian10_all.deb
dpkg -i zabbix-release_5.4-1+debian10_all.deb
apt install zabbix-web-service
I eddited zabbix_web_service.conf:
AllowedIP=127.0.0.1,::1,0.0.0.0/0,zabbix
I edited zabbix_server.conf:
StartReportWriters=1
WebServiceURL=http://localhost:10053/report
I eddited settings in Zabbix Frontend - Administration -> General -> Other
Frontend URL: http://localhost:8085 (frontend is available at port 8085)
But when I try to test report generating i get error:
Cannot connect to web service: couldn't connect to server
I've already tried with other Frontend URLs, but nothings seems to work. I tried with:
http://localhost:10053/report
http://192.168.10.18:8085/
http://192.168.10.18:10053/report
I've verified that I get answear from http://192.168.10.18:10053/report :
{"detail":"Method is not supported."}
What else can I check/try?
I found the problem. In server configuration I was usinng address http://localhost:10053/report it was wrong because in my case Zabbix server is running in docker and Zabbix web service is not running in docker. Zabbix server wasn't albe to connect to web servcie because it was in the other network. I changed the configuration and now everything works fine. Reports are beeing generated and send

I have a dedicated server running Ubuntu and Rancher Desktop.
I'd like to be able to access the Kubernetes cluster (K3S) from another computer in the same network.
In doing so, after I've setup my kube configuration, I'm getting an error.
Unable to connect to the server: x509: certificate is valid for 10.43.0.1, 127.0.0.1, 192.168.5.15, ::1, fec0::5055:55ff:fe8e:47db, not 192.168.1.8
Passing the following config through to K3S should solve my problem
INSTALL_K3S_EXEC="--tls-san 192.168.1.8"
Reading through Rancher Desktop documentation, I found a potential solution.
Based on the documentation I should be able to pass config through to k3s via the Provisional Script for Rancher Desktop. It is still unclear to me as how I do this for the K3S configurations.
The k3s repository has this issue with a proposed solution at https://github.com/k3s-io/k3s/issues/3369
"SANs should be added to the dynamiclistener cert on demand, based on the SNI hostname requested by the client. Try running the following on the server:"
curl -vk --resolve 172.31.13.97:6443:127.0.0.1 https://172.31.13.97:6443/ping
I am user of Openshift online and OKD. I am facing similar issue in both places. Please have a look.
I have created a project.
I have launched php in Developer's Catalog option. With other details, I entered my project's git url, project is cloned successfully. Now it needs to connect to mysql database only.
In Pods, I deployed mysql image from 'Deploy Image' option. It is launched successfully.
When I make mysql connection from php pod to mysql pod, it does not connect, connection time out.
How should I make connection?
Note :
I do not have datastore option to launch mysql from developer's catalog in openshift online, that's why I am launching mysql image from deploy image.
As you mentioned you are using Openshift Online and OKD and you are facing the issue at both places.
You can not create mysql from development store because currently, the OpenShift Online catalog does not provide MySQL template via the web interface directly, but you can deploy the MySQL template using the oc CLI instead. The database deployment is simplified when using templates.
Once logged in with the oc CLI, running
oc new-app -L
will list all of the templates that we were used to seeing in the web console, including the mysql-persistent. Then, you can specify all the template parameters via the oc CLI, e.g.:
oc new-app mysql-persistent -p MYSQL_USER=<desired_DB_username> -p MYSQL_PASSWORD=<mysql_password> -p MYSQL_DATABASE=<desired_database_name>
If you'd like to see all the supported template parameters, you can use
oc process <template_name> --parameters -n openshift
or, for a more detailed output,
oc describe template <template_name> -n openshift
Once the app is launched successfully, you can find this app's hostname in services and connect to it from your php pod after defining host name in php configuration file.
I tried to install Context Broker version 1.7.0 on my Centos 6 VM.
I successfully installed it but while the service is running ,when i make a request with curl i get the message "couldn't connect to host"
I checked the port 1026 and the firewall and everything is ok.
Any ideas what may be the problem?
The best way to install Orion is using Docker to test or study: (https://hub.docker.com/r/fiware/orion/).
Docker and docker-compose. You install Orion and Mongodb together, in a quick time. (https://github.com/telefonicaid/fiware-orion/tree/master/docker)
Have you tried using this method?
With it you can use the last stable version (1.10.0).
I recently deployed a .war from Netbeans IDE on my local machine to Amazon EC2. The Servlet in my Webapp used JBDC Connector/J, the jar file for which was copied into Libraries in Netbeans. The WebApp was working well on my local machine. But the logs of Tomcat on Amazon EC2 shows an error the host 'xyz' is not allowed to connect to this MySQL Server.
confirm host information for mysql - run this on mysql:
select host, user from mysql.user;
If your host/port information is correct, try checking privileges being used for the web application. Also, make sure that your database server is able to bind on the specified port (netstat -an | grep 'port number') & that the client app can connect to that port (on the host). hope it helps
I have looked at lots of forms and threads on this site.
First I installed MySQL using msi installer.
Configuration settings:
- detailed configuration
- developer machine
- multifunctional database
- initial path
- decision support
- enable tcp/icp networking, port 3306, add firewall exception for this port.
- enable strict mode
- best support for multilangualism
- install as windows service, include bin directory
- entered root password.
Then when I clicked execute it freezes after writing the configuration file.
- I closed that window.
Then when I opened MySQL Command Line Client and typed in the root password i get this..
ERROR 2003: Can't connect to to MySQL server (10060)
I then opened up command prompt and typed.
C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld --install
got message:
Install/remove of this service denied.
I ran the initial configuration as administrator and I have checked that port 3306 is open.
Hope this is detailed enough.
Thanks.
I would suggesting uninstalling them all and reinstalling them with a package such as LAMP (for linux) or XAMPP (for windows). Much easier to install and set up, tutorials everywhere.
Can you get to the MySQL server instance config wizard in start menu
Is the MySQL service running?
whats the conf file look like?
