Installation

Cypht has four differents installation ways:

Please read the bellow explanations about each way and pick one of your choice.

1. Manual installation

Requirements

Cypht requires at least PHP 5.6 for version 1.4.x, the upcoming Cypht 2.0 will require PHP 7.4,Composer 2, and at minimum the OpenSSL, mbstring and cURL extensions. Cypht can also leverage several other extensions as defined in composer.json. Testing is done on Debian and Ubuntu platforms with Nginx and Apache.

Before proceeding please make sure your system meets minimal requirements

Steps

1. Check minimum requirements

#!/bin/bash

# You need to check php version which should be >=5.6 for version 1.4.x and 7.4 for upcoming Cypht version 2.0
php --version

# Next you need to check composer version which should be >=2.0.0
composer --version

# List installed PHP extensions. at least OpenSSL, mbstring and cURL should be in the list
php -m

2. Download and prepare the code

It's important to consider where you put the Cypht source. The web-server will need read-only access to it, and moving it from one place to another requires re-running the configuration script. Do NOT put the source in the document root as this could create a security risk. On Debian, it's common to use the /usr/local/share/ sub-directory for a situation like this. Here is short bash script that will download the latest code, setup the correct permissions and ownership, put the source in /usr/local/share/cypht, and create a default hm3.ini file. It requires sudo access: 

#!/bin/bash

# this is where Cypht will be installed
DESTINATION="/usr/local/share/cypht"

# validate the destination directory
sudo test -r $DESTINATION -a -x $DESTINATION
if [ $? -ne 0 ]; then
    sudo mkdir $DESTINATION
fi

# create working directory
mkdir cypht-temp
cd cypht-temp

# grab latest code
wget https://github.com/cypht-org/cypht/archive/1.4.x.zip

# unpack the archive
unzip 1.4.x.zip

# run composer
cd cypht-1.4.x && composer install && cd ..

# create a vanilla ini file
cp cypht-1.4.x/hm3.sample.ini cypht-1.4.x/hm3.ini

# fix permissions and ownership
find cypht-1.4.x -type d -print | xargs chmod 755
find cypht-1.4.x -type f -print | xargs chmod 644
sudo chown -R root:root cypht-1.4.x

# copy to destination folder
sudo mv cypht-1.4.x/* $DESTINATION

# remove working directory
cd ..
sudo rm -rf cypht-temp

3. Configure the program

To configure Cypht for your environment, you must first edit the hm3.ini file to your liking, then run the config_gen.php script to generate the optimized configuration file and assets used at run-time.

First edit the hm3.ini file to configure Cypht for your environment. If you choose to use a database for any of the 3 available purposes (authentication, sessions, or user settings), you will need to complete the "DB support" section and create the required tables. SQL to do so can be found in the hm3.sample.ini file. The ini file has lots of comments explaining what each option does.

Cypht needs read, and read-write access to a few directories on the server. For security reasons these should NOT be inside the web-server document root. A good place for these is under the /var/lib/ sub-directory. Here are the commands To create the required directories per the default values in the ini file (assuming your web-server software runs as the "www-data" user).

sudo mkdir /var/lib/hm3
sudo mkdir /var/lib/hm3/attachments
sudo mkdir /var/lib/hm3/users
sudo mkdir /var/lib/hm3/app_data
sudo chown -R www-data /var/lib/hm3/

The "/var/lib/hm3/users" directory is only required if you are using the file-system and not a database to store user settings (user_config_type = file in the hm3.ini). You can put these directories anywhere, just make sure the values in the ini file point to the right place.

4. Generate the run-time configuration

Cypht uses a build process to create an optimized configuration, and to combine and minimize page assets. Once you have edited your hm3.ini file, generate the configuration with:

cd /usr/local/share/cypht  (or wherever you put the code in section 1)
sudo php ./scripts/config_gen.php

This will create a sub-directory called site that contains the code and page assets that need to be inside the document root, and it creates an optimized configuration file called hm3.rc in the current directory. Anytime you change the ini file settings, or move the source location, you will need to re-run the config_gen script to update the program.

5. Enable the program in your web-server

The easiest way to serve Cypht is to symlink it to the web-server document root. You can also copy the generated files to your web-server location, but then you will need to re-copy them anytime the config_gen script is run. If the source is located at /usr/local/share/cypht, and the web-server document root is at /var/www/html, the following command will make Cypht available under the "mail" path of the web-server:

sudo ln -s /usr/local/share/cypht/site /var/www/html/mail

Now going to https://your-server/mail/ should load the Cypht login page. Note that If you use a symlink, your web-server must be configured to follow symlinks.

6. Users

Setting up users depends on what type of authentication you configure in the hm3.ini file. If you are using the local database configuration for users, there are scripts in the scripts/ directory to help manage them: 

# create an account
php ./scripts/create_account.php username password

# delete an account
php ./scripts/delete_account.php username

# change an account password
php ./scripts/update_password.php username password

7. Debug mode

Cypht has a debug or developer mode that can be used to troubleshoot problems or enable faster development of modules. To enable the debug version of Cypht, just sym-link the entire source directory instead of the site sub-directory:

sudo ln -s /usr/local/share/cypht /var/www/html/mail-debug

Debug mode is not as efficient as the normal version, and it is NOT designed to be secure. DO NOT RUN DEBUG MODE IN PRODUCTION. You have been warned! Debug mode outputs lots of information to the PHP error log that can be useful for trouble-shooting problems. The location of the error log varies based on your php.ini settings and web-server software.

8. Other INI files

Some Cypht modules require additional ini files to be configured. These should NOT be inside the web-server document root. Cypht will look for them in the location defined by "app_data_dir" in the hm3.ini file. A sample ini file for each module set that requires one is included in the source for that module. To configure them you must copy the sample ini file to the "app_data_dir" and edit it for your setup. Some of these require configuring your service with a provider, specifically ones related to Oauth2 client setup (Github, WordPress, Oauth2 over IMAP for Gmail and Outlook). Re-run the config_gen script after configuring an ini file and it will be merged into the main configuration settings.

2. Install cypht using Docker

Using Docker is one of the easiest way to install cypht as the cypht docker image comes with all the steps required in the manual instalation done for you. But the bad news is that this instllation way requires docker knowledge.
Here is the cypht docker repository: https://hub.docker.com/r/sailfrog/cypht-docker
To run containers required by cypht, please, first make sure you have docker and docker-compose installed on your system, then take a look on the section "exemple docker-compose" of repository overview, then do the following:

NOTE: Please change usernames and passwords before using the given docker-compose code in your production environment.

3. Install Cypht on a YunoHost server

This is an other easy way of installing and use Cypht.
YunoHost is an operating system that aims to simplify server administration as much as possible to democratize self-hosting while remaining reliable, secure, ethical and lightweight. It is a free software project owned exclusively by volunteers. Technically, it can be seen as a distribution based on Debian GNU/Linux and can be installed on many types of hardware.

To install Cypht on YunoHost, please follow these steps:

4. Install Cypht within Tiki
