This guide should work on most debian systems including Ubuntu. For installation guide on installing emoncms on a raspberrypi see raspberrypi installation guides.
You may need to start by updating the system repositories
sudo apt-get update
Install all dependencies:
sudo apt-get install apache2 mysql-server mysql-client php5 libapache2-mod-php5 php5-mysql php5-curl php-pear php5-dev php5-mcrypt php5-json git-core redis-server build-essential ufw ntp
Install pecl dependencies (serial, redis and swift mailer)
sudo pear channel-discover pear.swiftmailer.org
sudo pecl install channel://pecl.php.net/dio-0.0.6 redis swift/swift
Add pecl modules to php5 config
sudo sh -c 'echo "extension=dio.so" > /etc/php5/apache2/conf.d/20-dio.ini'
sudo sh -c 'echo "extension=dio.so" > /etc/php5/cli/conf.d/20-dio.ini'
sudo sh -c 'echo "extension=redis.so" > /etc/php5/apache2/conf.d/20-redis.ini'
sudo sh -c 'echo "extension=redis.so" > /etc/php5/cli/conf.d/20-redis.ini'
Emoncms uses a front controller to route requests, modrewrite needs to be configured:
$ sudo a2enmod rewrite
For <Directory /> and <Directory /var/www/> change AllowOverride None to AllowOverride All. This may be on lines 7 and 11 of /etc/apache2/sites-available/000-default. Modern versions of Ubuntu store these in the main config file: /etc/apache2/apache2.conf.
$ sudo nano /etc/apache2/sites-available/000-default
or
$ sudo nano /etc/apache2/apache2.conf
[Ctrl + X ] then [Y] then [Enter] to Save and exit.
Restart the lamp server:
$ sudo /etc/init.d/apache2 restart
Git is a source code management and revision control system but at this stage we use it to just download and update the emoncms application.
First cd into the var directory:
$ cd /var/
Set the permissions of the www directory to be owned by your username:
$ sudo chown $USER www
Cd into www directory
$ cd www
Download emoncms using git:
$ git clone https://github.com/emoncms/emoncms.git
Once installed you can pull in updates with:
$ cd /var/www/emoncms
$ git pull
$ mysql -u root -p
Enter the mysql password that you set above. Then enter the sql to create a database:
mysql> CREATE DATABASE emoncms;
Then add a user for emoncms and give it permissions on the new database (think of a nice long password):
mysql> CREATE USER 'emoncms'@'localhost' IDENTIFIED BY 'YOUR_SECURE_PASSWORD_HERE';
mysql> GRANT ALL ON emoncms.* TO 'emoncms'@'localhost';
mysql> flush privileges;
Exit mysql by:
mysql> exit
sudo mkdir /var/lib/phpfiwa
sudo mkdir /var/lib/phpfina
sudo mkdir /var/lib/phptimeseries
sudo chown www-data:root /var/lib/phpfiwa
sudo chown www-data:root /var/lib/phpfina
sudo chown www-data:root /var/lib/phptimeseries
cd into the emoncms directory where the settings file is located
$ cd /var/www/emoncms/
Make a copy of default.settings.php and call it settings.php
$ cp default.settings.php settings.php
Open settings.php in an editor:
$ nano settings.php
Update your database settings to use your new secure password:
$username = "USERNAME";
$password = "YOUR_SECURE_PASSWORD_HERE";
$server = "localhost";
$database = "emoncms";
You will also want to modify SMTP settings and the password reset flag further down in the settings file.
Save (Ctrl-X), type Y and exit
cd /var/www/emoncms/Modules
git clone https://github.com/emoncms/raspberrypi.git
git clone https://github.com/emoncms/event.git
git clone https://github.com/emoncms/openbem.git
git clone https://github.com/emoncms/energy.git
git clone https://github.com/emoncms/notify.git
git clone https://github.com/emoncms/report.git
git clone https://github.com/emoncms/packetgen.git
git clone https://github.com/elyobelyob/mqtt.git
See individual module readme's for further information on individual module installation.
The first time you run emoncms it will automatically setup the database and you will be taken straight to the register/login screen.
Create an account by entering your email and password and clicking register to complete.
Chrome Ubuntu 23.0.1271.97 - developed with, works great.
Chrome Windows 25.0.1364.172 - quick check revealed no browser specific bugs.
Firefox Ubuntu 15.0.1 - no critical browser specific bugs, but movement in the dashboard editor is much less smooth than chrome.
Internet explorer 9 - works well with compatibility mode turned off. F12 Development tools -> browser mode: IE9. Some widgets such as the hot water cylinder do load later than the dial.
IE 8, 7 - not recommended, widgets and dashboard editor do not work due to no html5 canvas fix implemented but visualisations do work as these have a fix applied.
Dashboard editing needs to pass parameters through HTTP-GET mechanism and on Debian 6 the max allowable length of a single parameter is very small (512 byte). This is a problem for designing of dashboard and when you exceed this threshold all created dashboard are lost...
To overcome this problem modify "suhosin.get.max_value_length" in /etc/php5/conf.d/suhosin.ini" to large value (8000, 16000 should be fine).
Follow the guide here step 4 onwards: http://emoncms.org/site/docs/gettext
PHP 5.4.0 has removed the timezone guessing algorithm and now defaults the timezone to "UTC" on some distros (i.e. Ubuntu 13.10). To resolve this:
Open php.ini
sudo vi /etc/php5/apache2/php.ini
and search for "date.timezone"
[Date]
; Defines the default timezone used by the date functions.
; http://php.net/date.timezone
;date.timezone =
edit date.timezone to your appropriate timezone:
date.timezone = "Europe/Amsterdam"
PHP supported timezones are listed here: http://php.net/manual/en/timezones.php
Now save and close and restart your apache.
sudo /etc/init.d/apache2 restart
sudo pear channel-discover pear.apache.org/log4php
sudo pear install log4php/Apache_log4php
ensure that log file has write permissions for www-data, pi and root.
sudo chmod 660 emoncms.log
