Change PHP version on Apache

You can install multiple PHP versions on your system and switch PHP version between them.

Example:

The PHP 5.6 is set as default version in your system, and you need to switch to PHP 7.2. Run the following commands to switch for Apache and command line.

sudo a2dismod php5.6 sudo a2enmod php7.2 sudo service apache2 restart

sudo update-alternatives --set php /usr/bin/php7.2 sudo update-alternatives --set phar /usr/bin/phar7.2 sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.2 sudo update-alternatives --set phpize /usr/bin/phpize7.2 sudo update-alternatives --set php-config /usr/bin/php-config7.2

Install Kannel – for dummies :)

Kannel is a compact and very powerful open source WAP and SMS gateway, used widely across the globe both for serving trillions of short messages (SMS), WAP Push service indications and mobile internet connectivity.

There are many tutorials “How to install kannel” but there is no “for dummies” one so I decided to make one 🙂

This procedure to install kannel is tested and adjusted on Ubuntu Server with LAMP installed on.

Install kannel procedure:

move to home folder
```
 cd /home
```

execute all these commands

```
sudo apt-get update
```
```
sudo apt-get install build-essential
```
```
sudo apt-get install bison
```
```
sudo apt-get install libmysqld-dev
```
```
sudo apt-get install libxml2-dev
```
```
sudo apt-get install subversion
```

svn co https://svn.kannel.org/gateway/trunk

change name of downloaded folder
```
mv trunk kannel
```
enter new directory
```
cd kannel
```

execute all these commands

```
sudo ./configure --with-mysql
```
```
sudo make
```

sudo make bindir=/home/kannel/bin install

enter directory
```
cd /home/kannel/addons/sqlbox
```

execute all these commands

sudo ./configure --with-kannel-dir=/home/kannel

```
sudo make
```
```
sudo make install
```

enter new directory
```
cd /home/kannel/addons/opensmppbox
```

execute all these commands

sudo ./configure --with-kannel-dir=/home/kannel

```
sudo make
```
```
sudo make install
```

And Kannel is installed successfully.
