Problem
You are trying to use the github OAuth authentication for having users login to your Grafana but there is an error that redirect_uri must match that is coming from Github.
Solution
Make sure that you add a line with the root_url in your /etc/grafana/grafana.ini file that has the same IP/domain name as your server, and restart the service.
root_url = http://xxxx.xxxx.xxxx.xxxx:3000
Problem
You would like to have a list of all the services (running and stopped) in a debian system.
Solution
You can run the following to see the list of services:
service --status-all
Problem
You have made some changes to the NGINX configuration and you would like to reload them without stopping and starting the server.
Solution
Use the following:
kill -HUP $(cat /var/run/nginx.pid)
Problem
You are trying to install/remove a package but you always get an error message about linux message as above:
Errors were encountered while processing: linux-image-3.13.0-128-generic
Solution
Try the following:
rm -rf /var/lib/dpkg/info/linux-image-3.13.0-128-generic.* apt-get purge linux-image-3.13.0-128-generic
Problem
You would like to know the codename (release) name of your Debian/Ubuntu system. Running cat /etc/issue will give you the release version but not the number.
Solution
Run the following command to get your release name:
lsb_release -cs
Problem
When you are trying to install a package inside a debian Docker container you get the following error message:
FATAL -> Failed to fork.
Solution
This is an indication of ‘out of memory’ so add a swap partition if it does not exist, on the host with the following:
fallocate -l 4G /swapfile chmod 600 /swapfile mkswap /swapfile swapon /swapfile echo "/swapfile swap swap sw 0 0" >> /etc/fstab
(Thanks Valent)
Problem
You want to install some default locales in a Docker image, and the suggestion is to use locale-gen to do so, but it does not work as expected.
Solution
In order to be able to use the locale-gen and install the locales you need you will have to uncomment the ones needed from /etc/locale.gen first and then use the locale-gen. Example below:
## Set up locales ## Uncomment the ones we need as locale-gen does not work without that RUN sed -i '/en_US.UTF-8/s/^#//' /etc/locale.gen RUN sed -i '/de_DE.UTF-8/s/^#//' /etc/locale.gen ## Now install them and set the default one RUN locale-gen ENV LANG en_US.UTF-8 ENV LANGUAGE en_US:en ENV LC_ALL en_US.UTF-8
Problem
When trying to connect with ssh to a linux (debian- ubuntu) server you get the following error:
bash: warning: setlocale: LC_ALL: cannot change locale (en_GB.UTF-8)
Solution
The reason is that the server is missing the en_US locale that your client is trying to use to connect to the server.
Login to the server and by using sudo (or su) run the following to install the missing en_US locale and make sure that you leave default to ‘None’ as described here:
dpkg-reconfigure locales
As an addition to the excellent beta book ‘Deploying Rails’, as I had problems using the suggested lucid64 image, I’ve tried to install a debian lenny 32 image with rvm and Ruby 1.9.3.
The steps needed are listed below
localhost$ vagrant box add debian-lenny-32 https://s3-eu-west-1.amazonaws.com/glassesdirect-boxen/debian/debian_lenny_32.box
localhost$ mkdir -p ~/deployingrails/lenny32
localhost$ cd ~/deployingrails/lenny32 vagrant init
Vagrant::Config.run do |config| config.vm.box = "lenny32" end
localhost$ vagrant up
localhost$ vagrant ssh vagrant$ sudo apt-get update vagrant$ sudo apt-get upgrade
localhost$ vagrant reload
localhost$ vagrant ssh
Install curl to be able to download the installation script for:
vagrant$ sudo apt-get install curl
vagrant$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
vagrant$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bashrc
vagrant$ source ~/.bashrc
vagrant$ type rvm | head -1 rvm is a function
vagrant$ sudo apt-get install build-essential openssl curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison
vagrant$ rvm install ruby-1.9.3
vagrant$ rvm use 1.9.3 --default
localhost$ vagrant package --output lenny32-rvm-ruby193
localhost$ vagrant box add lenny32-rvm-ruby193 lenny32-rvm-ruby193 localhost$ vagrant box list
Problem
You would like to (re)-install passenger after a system wide rvm installation, but you only have the mod_passenger.c file and not the .so after the gem installation.
Solution
Make sure that after using gem install passenger you also use the command to install the apache2 passenger module:
passenger-install-apache2-module
you should then be able to see the .so file and add it to your /etc/apache2/mods-available/passenger.load
