# INSTALLATION INSTRUCTIONS
## for Debian 9.9 "stretch"

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

!!! notice
    Please use [Debian 10](https://misp.github.io/MISP/xINSTALL.debian10/) as everything works as expected.


!!! notice
    Maintained and tested by @SteveClement on 20190702

!!! warning
    This install document is compiles a custom Python 3.7 meaning some things might be unexpected.
    Debian stretch has Python 3.5 but we need at least python 3.6


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

#### Install a minimal Debian 9.9 "stretch" server system with the software:
- OpenSSH server
- This guide assumes a user name of 'misp' with sudo working

{!generic/known-issues-debian.md!}

{!generic/globalVariables.md!}

```bash
PHP_ETC_BASE=/etc/php/7.0
PHP_INI=${PHP_ETC_BASE}/apache2/php.ini

sudo adduser $MISP_USER staff
sudo adduser $MISP_USER $WWW_USER
```

{!generic/sudo_etckeeper.md!}

{!generic/ethX.md!}

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

#### 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 use at least Python3.6 for [PyMISP](https://github.com/MISP/PyMISP) to work properly.

```bash
# Manual Python3.7.3 install in $HOME
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev -qqy
mkdir -p ~/opt/python3
cd /tmp
wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
tar xvfJ Python-3.7.3.tar.xz
rm Python-3.7.3.tar.xz
cd Python-3.7.3
# --enable-optimizations will run tests to optimize the resulting python binary, this takes time and is expected
./configure --enable-optimizations --with-ensurepip=install --prefix="$HOME"/opt/python3
make -j3
make altinstall
sudo apt install virtualenv -qqy
```

```bash
sudo apt install \
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 \

net-tools -qqy

sudo apt install libapache2-mod-php php php-cli php-mbstring php-dev php-json php-xml php-mysql php7.0-opcache php-readline php-redis php-gnupg php-gd -qqy

sudo apt install \
mariadb-client \
mariadb-server -qqy

# Just a quick test if mysql-server restarts without problems
sudo /etc/init.d/mysql restart

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

sudo apt install expect -qqy

# Add your credentials if needed, if sudo has NOPASS, comment out the relevant lines
pw="Password1234"

expect -f - <<-EOF

cd $PATH_TO_MISP
$SUDO_WWW git clone https://github.com/MISP/MISP.git $PATH_TO_MISP

```

### 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 $WWW_USER:$WWW_USER /var/www/.composer
# Update composer.phar
# $SUDO_WWW php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
# $SUDO_WWW php -r "if (hash_file('SHA384', 'composer-setup.php') === 'a5c698ffe4b8e849a443b120cd5ba38043260d5c4023dbf93e1558871f1f07f58274fc6f4c93bcfd858c6bd0775cd8d1') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
# $SUDO_WWW php composer-setup.php
# $SUDO_WWW php -r "unlink('composer-setup.php');"
$SUDO_WWW php composer.phar require kamisama/cake-resque:4.1.2
$SUDO_WWW php composer.phar config vendor-dir Vendor
$SUDO_WWW 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_WWW 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 $WWW_USER:$WWW_USER $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_WWW 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)
```

```bash
# activate new vhost

# Restart apache
sudo systemctl restart apache2
```

### 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
```

### 9/ MISP configuration
---------------------
```bash
# There are 4 sample configuration files in $PATH_TO_MISP/app/Config that need to be copied

### 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
    ```

#### MISP has a new pub/sub feature, using ZeroMQ. To enable it, simply run the following commands

```bash
$SUDO_WWW ${PATH_TO_MISP}/venv/bin/pip install pyzmq
```

#### MISP has a feature for publishing events to Kafka. To enable it, simply run the following commands
```bash
sudo apt install librdkafka-dev php-dev
sudo pecl channel-update pecl.php.net
sudo pecl install rdkafka
