Please read [[Docker HowTo Install]] before installing REDcap

== Prerequisites if required

'''Step 1 - Install Docker'''

[[Docker HowTo Install]]

'''Step 2 - Install Git''' 

    {{{$ sudo apt-get update }}}

    {{{$ sudo apt-get install git }}}

'''Step 3 - Install NGINX'''

[[NGINX HowTo Install Using Docker]]

'''Step 4 - Backup Redcap Database'''

Log on to the mysql database machine.

    {{{/usr/local/mysql/bin/mysqldump --routines --skip-extended-insert --force -h localhost -u root -p redcap > $(date +\%d-\%m-\%Y-)_redcap.sql }}}

This will create a database dump file.

Connect to my sql.

    {{{mysql -u root -p}}}

Create a database, make sure you postfix with Redcap version number. Please stick to this naming convention. 

    {{{mysql > create database redcap6168}}}

Import the lastest database.

    {{{mysql -u root -p -h localhost redcap6168 < 19-09-2016-_redcap.sql}}}

'''Step 5 - Create / Grant Mysql permissions'''

If a new user is needed run the following, replace necessary details

    {{{CREATE USER 'briccsext02_user'@'uhlbriccsext02.xuhl-tr.nhs.uk' IDENTIFIED BY 'password'}}}

Grant necessary privileges to user.
 
    {{{GRANT USAGE ON *.* TO 'briccsext02_user'@'uhlbriccsext01.xuhl-tr.nhs.uk' IDENTIFIED BY 'password'}}}

    {{{GRANT ALL PRIVILEGES ON redcap6168_briccsext.* TO 'briccsext02_user'@'%';}}}

    {{{GRANT ALL PRIVILEGES ON redcap6168_briccsext.* TO 'briccsext02_user'@'%';}}}

If user already exists

    {{{GRANT ALL PRIVILEGES ON redcap6168.* TO 'redcap'@'%';}}}

    {{{GRANT ALL PRIVILEGES ON redcap6168.* TO 'briccsext02_user'@'%';}}}

or

    {{{GRANT ALL PRIVILEGES ON redcap6168_briccsext.* TO 'briccsext_user'@'uhlbriccsext01.xuhl-tr.nhs.uk';}}}

You have the choice of either upgrading Redcap or installing a fresh version of Redcap

== Installs

1. On the host machine go to directory

    {{{/local/docker/<USER>/}}}

2. Go to this directory and checkout from git docker_redcap_upgrade

    {{{sudo git clone https://github.com/LCBRU/docker_redcap_upgrade.git}}}

    {{{sudo chmod -R 777 docker_redcap_upgrade/}}}

This will create a directory /local/docker/<USER>/docker_redcap_upgrade

This docker script upgrades an existing redcap installation. 

The first step is to zip the existing redcap installation, this could be either 

3. The directory /var/www/redcap on a virtual machine. 

    {{{cd /var/www}}}

    {{{sudo zip -r redcap_v5.7.0.zip redcap}}}

Move this file into /home/<USER>/docker_redcap_upgrade

4. The directory /var/www/redcap within a running Docker container. 

   Connect to existing docker container using

   {{{sudo docker exec -i -t <CONTAINERID> /bin/bash}}}

   {{{cd /var/www/site/redcap}}}

   {{{sudo zip -r redcap_v5.7.0.zip *}}}

   {{{sudo mv redcap_v5.7.0.zip /share/}}}

   {{{exit}}}

redcap_v5.7.0.zip should now be available on the host machine. In the directory /share/

Move this file into /home/<USER>/docker_redcap_upgrade

5. Now edit Dockerfile

Amend the line # Old Redcap

Amend all instance of latest Redcap, i.e redcapX.XX.X_upgrade.zip, redcap_vX.XX.X. Please use a copy and replace.

6. Edit database.php

Add entries for the database.

Ensure salt entry is exactly same as old version of redcap

7. Build Docker container

   {{{sudo docker build -t lcbruit/redcap_upgrade:v6.16.8 .}}}

8. Run container

   {{{sudo docker run -v /share:/share -itd -p 82:80 lcbruit/redcap_upgrade:v6.16.8}}}

9. Open URL

   {{{http://<HOST>.xuhl-tr.nhs.uk:82/redcap/redcap_v6.16.8/upgrade.php}}}

10. This url will give you a sql script that you run against the database. Download the sql file and place it on the mysql host. Run as follows :

   {{{mysql -u root -p redcap6168 < redcap_upgrade_61608.sql}}}

== Upgrade

1. Download the Redcap upgrade from https://community.projectredcap.org/page/download.html

2. Backup your database or copy the most recent database from {{{/var/MySqlBackerUpper/data/latest}}}.

3. Amend the backup file to change the database name using the following command:
{{{
sed -i.bak 's/redcap{old_version}_briccs/redcap{new_version}_briccs/g' {copy of backup file}
}}}

4. Create the database:
{{{
mysql < {copy of backup file}
}}}

5. Grant redcap user permission to the new database:
{{{
GRANT SELECT ON redcap{version}.* TO  'redcap'@'%';
}}}

6. Connect to your docker redcap container

   {{{sudo docker exec -i -t <CONTAINERID> /bin/bash}}}

7. Unzip the contents of redcap7.X.X_upgrade.zip into /var/www/site/redcap

8. Change database.php with details of new database.

9. Open URL

   {{{http://<HOST>.xuhl-tr.nhs.uk/redcap/redcap_v7.X.X/upgrade.php}}}

10. This url will give you a sql script that you run against the database. Download the sql file and place it on the mysql host. Run as follows :

   {{{mysql -u root -p redcap6168 < redcap_upgrade_XXXXX.sql}}} 

11. Now modify lcbruit/redcap_fresh docker image. This is very important as it will replace you current docker image.

   Download the fresh install package from redcap and modify the Dockerfile in redcap_fresh to use it.

12. Build and run the redcap_fresh container :

   {{{sudo docker build -t lcbruit/redcap_fresh:v6.16.6 .}}}

   {{{sudo docker run -itd -p 80:80 lcbruit/redcap_fresh:v6.16.6}}}  

13. Ensure you have set the container to start on reboot with the correct version number
