# INSTALLATION INSTRUCTIONS
## for Debian 9.8 "stretch"

### 0/ MISP debian stable install - Status
--------------------------------------

!!! notice
    Maintained and tested by @SteveClement on 20190405

!!! warning
    This install document is NOT working as expected. There are Python issues as we "only" have python 3.5 but need at least python 3.6
    This guide effectively converts your "stretch" install into a partial "testing" install.
    Thus following the "testing" install guide is a better choice, but not for production.
    One manual work-around is to install Python >3.5 from source.

### 1/ Minimal Debian install
-------------------------

#### Install a minimal Debian 9 "stretch" server system with the software:
- OpenSSH server
- This guide assumes a user name of 'misp' with sudo working

{!generic/globalVariables.md!}

```bash
PHP_ETC_BASE=/etc/php/7.3
PHP_INI=${PHP_ETC_BASE}/apache2/php.ini
```

{!generic/sudo_etckeeper.md!}

{!generic/ethX.md!}

#### Make sure your system is up2date
```bash
sudo apt update
sudo apt -y dist-upgrade
```

#### install postfix, there will be some questions. (optional)
```bash
# Postfix Configuration: Satellite system
sudo apt install -y postfix
```

```bash
# change the relay server later with:
sudo postconf -e 'relayhost = example.com'
sudo postfix reload
```

### 2/ Install LAMP & dependencies
------------------------------

#### Install all the dependencies (some might already be installed)

You need to update python3.5 to python3.7 for [PyMISP](https://github.com/MISP/PyMISP) to work properly.

FIXME: The below breaks redis-server and mariadb-server

```bash
echo "deb http://ftp.de.debian.org/debian testing main" | sudo tee -a /etc/apt/sources.list
echo 'APT::Default-Release "stable";' | sudo tee -a /etc/apt/apt.conf.d/00local
sudo apt update
sudo apt-get -t testing install -y python3 python3-setuptools python3-dev python3-pip python3-redis python3-zmq virtualenv
```

```bash
sudo apt -t testing install -y \
curl gcc git gnupg-agent make openssl redis-server vim zip libyara-dev \
apache2 apache2-doc apache2-utils \
libpq5 libjpeg-dev libfuzzy-dev ruby asciidoctor \
jq ntp ntpdate imagemagick tesseract-ocr \
libxml2-dev libxslt1-dev zlib1g-dev \
net-tools

sudo apt -t testing install -y libapache2-mod-php7.3 php7.3 php7.3-cli php7.3-mbstring php7.3-dev php7.3-json php7.3-xml php7.3-mysql php7.3-opcache php7.3-readline php-redis php-gnupg php-gd

sudo apt -t testing install -y \
mariadb-client \

# This is maybe needed. If mysql does not start and you find a solution, please contribute.
# What did work for me was running mysqld interactively: sudo mysqld
mkdir -p /var/run/mysqld
chown mysql /var/run/mysqld
sudo /etc/init.d/mysql restart

sudo apt -t testing install -y jupyter-notebook

# Start haveged to get more entropy (optional)
sudo apt install haveged -y
sudo service haveged start

sudo apt install expect -y

# Add your credentials if needed, if sudo has NOPASS, comment out the relevant lines

sudo a2enmod headers
```

#### Apply all changes
```bash
sudo systemctl restart apache2
```

#### Fix redis-server

For some reason or another, redis-server startup scripts are broken, the below will fix this.

```bash
fixRedis () {
  # As of 20190124 redis-server init.d scripts are broken and need to be replaced
  sudo mv /etc/init.d/redis-server /etc/init.d/redis-server_`date +%Y%m%d`

### 4/ CakePHP
-----------
#### CakePHP is included as a submodule of MISP.

```bash
# Install CakeResque along with its dependencies if you intend to use the built in background jobs:
cd $PATH_TO_MISP/app
# Make composer cache happy
sudo mkdir /var/www/.composer ; sudo chown www-data:www-data /var/www/.composer
# Update composer.phar
sudo -H -u www-data php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
sudo -H -u www-data php -r "if (hash_file('SHA384', 'composer-setup.php') === '48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
sudo -H -u www-data php composer-setup.php
sudo -H -u www-data php -r "unlink('composer-setup.php');"
sudo -H -u www-data php composer.phar require kamisama/cake-resque:4.1.2
sudo -H -u www-data php composer.phar config vendor-dir Vendor
sudo -H -u www-data php composer.phar install

# Enable CakeResque with php-redis
sudo phpenmod redis
sudo phpenmod gnupg

# To use the scheduler worker for scheduled tasks, do the following:
sudo -u www-data cp -fa $PATH_TO_MISP/INSTALL/setup/config.php $PATH_TO_MISP/app/Plugin/CakeResque/Config/config.php
```


### 5/ Set the permissions
----------------------

```bash
# Check if the permissions are set correctly using the following commands:
sudo chown -R www-data:www-data $PATH_TO_MISP
sudo chmod -R 750 $PATH_TO_MISP
sudo chmod -R g+ws $PATH_TO_MISP/app/tmp
sudo chmod -R g+ws $PATH_TO_MISP/app/files
sudo chmod -R g+ws $PATH_TO_MISP/app/files/scripts/tmp
```


### 6/ Create a database and user
-----------------------------
#### Enter the mysql shell
```bash
sudo mysql -u root -p
```

```
MariaDB [(none)]> create database misp;
MariaDB [(none)]> grant usage on *.* to misp@localhost identified by 'XXXXdbpasswordhereXXXXX';
MariaDB [(none)]> grant all privileges on misp.* to misp@localhost;
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit
```

#### copy/paste:
```bash
sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "create database $DBNAME;"
sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "grant usage on *.* to $DBNAME@localhost identified by '$DBPASSWORD_MISP';"
sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "grant all privileges on $DBNAME.* to '$DBUSER_MISP'@'localhost';"
sudo mysql -u $DBUSER_ADMIN -p$DBPASSWORD_ADMIN -e "flush privileges;"
```

#### Import the empty MISP database from MYSQL.sql
```bash
sudo -u www-data cat $PATH_TO_MISP/INSTALL/MYSQL.sql | mysql -u $DBUSER_MISP -p$DBPASSWORD_MISP $DBNAME
```

### 7/ Apache configuration
-----------------------
```bash
# Now configure your Apache webserver with the DocumentRoot $PATH_TO_MISP/app/webroot/

# If the apache version is 2.4:
sudo cp $PATH_TO_MISP/INSTALL/apache.24.misp.ssl /etc/apache2/sites-available/misp-ssl.conf

# Be aware that the configuration files for apache 2.4 and up have changed.
# The configuration file has to have the .conf extension in the sites-available directory
# For more information, visit http://httpd.apache.org/docs/2.4/upgrading.html

# If a valid SSL certificate is not already created for the server, create a self-signed certificate:
sudo openssl req -newkey rsa:4096 -days 365 -nodes -x509 \
-subj "/C=${OPENSSL_C}/ST=${OPENSSL_ST}/L=${OPENSSL_L}/O=${OPENSSL_O}/OU=${OPENSSL_OU}/CN=${OPENSSL_CN}/emailAddress=${OPENSSL_EMAILADDRESS}" \
-keyout /etc/ssl/private/misp.local.key -out /etc/ssl/private/misp.local.crt

# Otherwise, copy the SSLCertificateFile, SSLCertificateKeyFile, and SSLCertificateChainFile to /etc/ssl/private/. (Modify path and config to fit your environment)
```

### 8/ Log rotation
---------------
```bash
# MISP saves the stdout and stderr of its workers in $PATH_TO_MISP/app/tmp/logs
# To rotate these logs install the supplied logrotate script:

sudo cp $PATH_TO_MISP/INSTALL/misp.logrotate /etc/logrotate.d/misp
sudo chmod 0640 /etc/logrotate.d/misp
```

### Optional features
-------------------
!!! note
    You can add the following to your shell startup rc scripts to have the *cake* and *viper-cli* commands in your $PATH
    ```bash
    # set PATH so it includes viper if it exists
    if [ -d "/usr/local/src/viper" ] ; then
        PATH="$PATH:/usr/local/src/viper"
    fi

    # set PATH so it includes viper if it exists
    if [ -d "/var/www/MISP/app/Console" ] ; then
        PATH="$PATH:/var/www/MISP/app/Console"
    fi
    ```
