I've been trying to configure Apache web server with a Spring Boot app that uses embedded Tomcat. Before Spring Boot I used to create an ajp.conf file like: <VirtualHost *:80> ServerName localhost <Proxy *> AddDefaultCharset Off Order deny,allow Allow from all </Proxy> ProxyPass /app ajp://localhost:8009/app ProxyPassReverse /app ajp://localhost:8009/app </VirtualHost> And include in the httpd.conf file like Include /opt/lampp/apache2/conf/ajp.conf And in the Tomcat's server.xml file, I used to configure it to listen to port 8009 <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"

I am trying to connect to Postgresql9.1 in ubuntu with pgadmin3. My Pgadmin3 GUI tool does not give any option to create tables by right clicking the database, but it is available in some videos I saw. Therefore, I used terminal to create the database and it showed up in pgadmin3. my file structure My Userdetails file package org.nitish.hiber; import javax.persistence.Entity; import javax.persistence.Id; @Entity public class UserDetails { @Id private int userId; private String userName; public int getUserId() { return userId; } public void setUserId(int userId) { this.userId = userId; } public

I followed DigitalOcean's tutorials on how to set up your server with SSH, creating a new user, firewalls etc. The first tutorial in the series is linked under: https://www.digitalocean.com/community/tutorials/how-to-connect-to-your-droplet-with-ssh I've also installed Webmin on my server, but I still can't get a connection to the server by using the web-browser. It just loads for a long time and then says it can't establish a connection. The URL's I've been using are: "Just-my-IP-adress" and " https://Just-my-IP-adress:10000 " The last one to open the Webmin administrator. I'm not sure what

I followed docker instructions to install and verify the docker installation (from http://docs.docker.com/linux/step_one/ ). I tried on 2 Ubuntu 14.04 machines and on both I got following error when starting docker daemon: $ sudo docker daemon INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) INFO[0000] [graphdriver] using prior storage driver "aufs" INFO[0000] Option DefaultDriver: bridge INFO[0000] Option DefaultNetwork: bridge WARN[0000] Running modprobe bridge nf_nat br_netfilter failed with message: modprobe: WARNING: Module br_netfilter not found. , error: exit status 1 INFO

When I run docker-compose up in my Docker project it failes with the following message: Error starting userland proxy: listen tcp 0.0.0.0:3000: bind: address already in use netstat -pna | grep 3000 shows this: tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN - I've already tried docker-compose down , but it doesn't help. In your case it was some other process that was using the port and as indicated in the comments, sudo netstat -pna | grep 3000 helped you in solving the problem. While in other cases (I myself encountered it many times) it mostly is the same container running at some other instance. In
