### 0/ Overview and Assumptions

!!! warning
    The core MISP team cannot easily verify if this guide is working or not. Please help us in keeping it up to date and accurate.
    Thus we also have difficulties in supporting RHEL issues but will do a best effort on a similar yet slightly different setup.

!!! notice
    Maintenance for CentOS 8 will end on: December 31st, 2021 [Source[0]](https://wiki.centos.org/About/Product) [Source[1]](https://linuxlifecycle.com/)
    Consider using [Rocky Linux](https://rockylinux.org/)
    CentOS 8 [NetInstallURL](http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=BaseOS)

{% include_relative generic/manual-install-notes.md %}

This document details the steps to install MISP on Red Hat Enterprise Linux 8.x (RHEL 8.x) and Rocky Linux 8.x.
This is a joint RHEL/Rocky install guide. The authors tried to make it contextually evident what applies to which flavor.

The following assumptions with regard to this installation have been made.

- A valid support agreement allowing the system to register to the Red Hat Customer Portal and receive updates
- The ability to enable additional RPM repositories, specifically the EPEL and Software Collections (SCL) repos
- This system will have direct or proxy access to the Internet for updates. Or connected to a Red Hat Satellite Server
- This document will bootstrap a MISP instance running over HTTPS. A full test of all features have yet to be done. [The following GitHub issue](https://github.com/MISP/MISP/issues/4084) details some shortcomings.

{% include_relative generic/globalVariables.md %}

!!! note
    For fresh installs the following tips might be handy.<br />
    Allow ssh to pass the firewall on the CLI
    ```bash
    firewall-cmd --zone=public --add-port=22/tcp --permanent
    firewall-cmd --reload
    ```
    <br />
    To quickly make sure if NetworkManager handles your network interface on boot, check in the following location:
    ```
    /etc/sysconfig/network-scripts/ifcfg-*
    ```

### 1/ OS Install and additional repositories

## 1.1/ Complete a minimal RHEL/Rocky installation, configure IP address to connect automatically.

## 1.2/ Configure system hostname (if not done during install)
```bash
sudo hostnamectl set-hostname misp.local # Your choice, in a production environment, it's best to use a FQDN
```

## 1.3/ **[RHEL]** Register the system for updates with Red Hat Subscription Manager
```bash
# <snippet-begin 0_RHEL_register.sh>
registerRHEL () {
  sudo subscription-manager register --auto-attach # register your system to an account and attach to a current subscription
}
# <snippet-end 0_RHEL_register.sh>
```

## 1.4/ **[RHEL]** Enable the optional repos (obsolete in v8)
```bash
# <snippet-begin 0_RHEL8_SCL.sh>
enableOptionalRHEL8 () {
  sudo subscription-manager refresh

  # The following is needed for -devel repos and ONLY for misp-modules, ignore if not needed
  sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
  # Software Collections is available for Red Hat Enterprise Linux 7 and previous supported releases. Starting with Red Hat Enterprise Linux 8, the content traditionally consumed via Software Collections is now part of Application Streams. Please see the Application Streams Life Cycle documentation for that release. Source: https://access.redhat.com/support/policy/updates/rhscl
}
# <snippet-end 0_RHEL8_SCL.sh>
```

## 1.5a/ Install the deltarpm package to help reduce download size when installing updates (optional)
```bash
sudo dnf install drpm -y
```

## 1.5.b/ Install vim (optional)
```bash
# Because (neo)vim is just so practical
sudo dnf install neovim -y || sudo dnf install vim -y || echo "neovim is not in the catalog"
# For RHEL, it's vim and after enabling epel neovim is available too
```

## 1.5.c/ Install ntpdate (optional)
```bash
# In case you time is wrong, this will fix it.
sudo dnf install ntpdate -y || sudo dnf install ntpsec -y || sudo dnf install chrony -y
sudo ntpdate pool.ntp.org
```

## 1.5/ Update the system and reboot
```bash
# <snippet-begin 0_yum-update.sh>
yumUpdate () {
  sudo dnf update -y
}
# <snippet-end 0_yum-update.sh>
```

## 1.6/ Install the EPEL and remi repo
```bash
# <snippet-begin 0_EPEL_REMI.sh>
enableEPEL_REMI_8 () {
  sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y
  sudo dnf install http://rpms.remirepo.net/enterprise/remi-release-8.rpm -y
  sudo dnf install dnf-utils -y
  sudo dnf module enable php:remi-7.4 -y
  ([[ ${DISTRI} == "centos8stream" ]] || [[ ${DISTRI} == "centos8" ]] || [[ ${DISTRI} == "rocky8.4" ]] || [[ ${DISTRI} == "rocky8.5" ]]) && sudo dnf config-manager --set-enabled powertools
}

enableREMI_fedora () {
  [[ "${DISTRI%??}" == "fedora" ]] && sudo dnf install http://rpms.remirepo.net/fedora/remi-release-${DISTRI:6}.rpm -y
  dnf list installed mod_lua && sudo dnf remove mod_lua -y
  sudo dnf install dnf-utils -y
  sudo dnf module enable php:remi-7.4 -y
}
# <snippet-end 0_EPEL_REMI.sh>
```

### 2/ Dependencies

!!! note
    This guide installs PHP 7.4 from Remi's repo

!!! warning
    [PHP 5.6 and 7.0 aren't supported since December 2018](https://secure.php.net/supported-versions.php). Please update accordingly. In the future only PHP7 will be supported.

## 2.01/ Install some base system dependencies

### 4/ CakePHP
## 4.01/ Install CakeResque along with its dependencies if you intend to use the built in background jobs

!!! notice
    CakePHP is now included as a submodule of MISP and has been fetch by a previous step.

```bash
# <snippet-begin 1_installCake_RHEL.sh>
installCake_RHEL ()
{
  sudo chown -R $WWW_USER:$WWW_USER $PATH_TO_MISP
  sudo mkdir /usr/share/httpd/.composer
  sudo chown $WWW_USER:$WWW_USER /usr/share/httpd/.composer
  cd $PATH_TO_MISP/app
  $SUDO_WWW php composer.phar install --no-dev

  sudo dnf install php-pecl-redis php-pecl-ssdeep php-pecl-gnupg -y

  sudo systemctl restart php-fpm.service

  # If you have not yet set a timezone in php.ini
  echo 'date.timezone = "Asia/Tokyo"' |sudo tee /etc/php-fpm.d/timezone.ini
  sudo ln -s ../php-fpm.d/timezone.ini /etc/php.d/99-timezone.ini

  # Recommended: Change some PHP settings in /etc/opt/remi/php74/php.ini
  # max_execution_time = 300
  # memory_limit = 2048M
  # upload_max_filesize = 50M
  # post_max_size = 50M
  for key in upload_max_filesize post_max_size max_execution_time max_input_time memory_limit
  do
      sudo sed -i "s/^\($key\).*/\1 = $(eval echo \${$key})/" $PHP_INI
  done
  sudo sed -i "s/^\(session.sid_length\).*/\1 = $(eval echo \${session0sid_length})/" $PHP_INI
  sudo sed -i "s/^\(session.use_strict_mode\).*/\1 = $(eval echo \${session0use_strict_mode})/" $PHP_INI
  sudo systemctl restart php-fpm.service

  # To use the scheduler worker for scheduled tasks, do the following:
  sudo cp -fa $PATH_TO_MISP/INSTALL/setup/config.php $PATH_TO_MISP/app/Plugin/CakeResque/Config/config.php
}
# <snippet-end 1_installCake_RHEL.sh>
```

### 5/ Set file permissions
```bash
# <snippet-begin 2_permissions_RHEL8.sh>
# Main function to fix permissions to something sane
permissions_RHEL8 () {
  sudo chown -R $WWW_USER:$WWW_USER $PATH_TO_MISP
  ## ? chown -R root:$WWW_USER $PATH_TO_MISP
  sudo find $PATH_TO_MISP -type d -exec chmod g=rx {} \;
  sudo chmod -R g+r,o= $PATH_TO_MISP
  ## **Note :** For updates through the web interface to work, apache must own the $PATH_TO_MISP folder and its subfolders as shown above, which can lead to security issues. If you do not require updates through the web interface to work, you can use the following more restrictive permissions :
  sudo chmod -R 750 $PATH_TO_MISP
  sudo chmod -R g+xws $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
  sudo chmod -R g+rw $PATH_TO_MISP/venv
  sudo chmod -R g+rw $PATH_TO_MISP/.git
  sudo chown $WWW_USER:$WWW_USER $PATH_TO_MISP/app/files
  sudo chown $WWW_USER:$WWW_USER $PATH_TO_MISP/app/files/terms
  sudo chown $WWW_USER:$WWW_USER $PATH_TO_MISP/app/files/scripts/tmp
  sudo chown $WWW_USER:$WWW_USER $PATH_TO_MISP/app/Plugin/CakeResque/tmp
  sudo chown -R $WWW_USER:$WWW_USER $PATH_TO_MISP/app/Config
  sudo chown -R $WWW_USER:$WWW_USER $PATH_TO_MISP/app/tmp
  sudo chown -R $WWW_USER:$WWW_USER $PATH_TO_MISP/app/webroot/img/orgs
  sudo chown -R $WWW_USER:$WWW_USER $PATH_TO_MISP/app/webroot/img/custom
}
# <snippet-end 2_permissions_RHEL8.sh>
```

### 6/ Create database and user

## 6.01/ Set database to listen on localhost only
```bash
# <snippet-begin 1_prepareDB_RHEL.sh>
prepareDB_RHEL () {
  # Enable, start and secure your mysql database server
  sudo systemctl enable --now mariadb.service
  echo [mysqld] |sudo tee /etc/my.cnf.d/bind-address.cnf
  echo bind-address=127.0.0.1 |sudo tee -a /etc/my.cnf.d/bind-address.cnf
  sudo systemctl restart mariadb

  # Kill the anonymous users
  sudo mysql -h $DBHOST -e "DROP USER IF EXISTS ''@'localhost'"
  # Because our hostname varies we'll use some Bash magic here.
  sudo mysql -h $DBHOST -e "DROP USER IF EXISTS ''@'$(hostname)'"
  # Kill off the demo database
  sudo mysql -h $DBHOST -e "DROP DATABASE IF EXISTS test"
  # No root remote logins
  sudo mysql -h $DBHOST -e "DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1')"
  # Make sure that NOBODY can access the server without a password

### 7/ Apache Configuration

!!! notice
    SELinux note, to check if it is running:
    ```bash
    $ sestatus
    SELinux status:                 disabled
    ```
    If it is disabled, you can ignore the **chcon/setsebool/semanage/checkmodule/semodule*** commands.

```bash
# <snippet-begin 1_apacheConfig_RHEL8.sh>
apacheConfig_RHEL8 () {
  # Now configure your apache server with the DocumentRoot $PATH_TO_MISP/app/webroot/

### 8/ Log Rotation
## 8.01/ Enable log rotation
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:

FIXME: The below does not work

```bash
# <snippet-begin 2_logRotation_RHEL.sh>
logRotation_RHEL () {
  # 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

  # Now make logrotate work under SELinux as well
  # Allow logrotate to modify the log files
  sudo semanage fcontext -a -t httpd_sys_rw_content_t "$PATH_TO_MISP(/.*)?"
  sudo semanage fcontext -a -t httpd_log_t "$PATH_TO_MISP/app/tmp/logs(/.*)?"
  sudo chcon -R -t httpd_log_t $PATH_TO_MISP/app/tmp/logs
  sudo chcon -R -t httpd_sys_rw_content_t $PATH_TO_MISP/app/tmp/logs
  # Impact of the following: ?!?!?!!?111
  ##sudo restorecon -R $PATH_TO_MISP

  # Allow logrotate to read /var/www

!!! note
    There is a bug that if a passphrase is added MISP will produce an error on the diagnostic page.<br />
    /!\ THIS WANTS TO BE VERIFIED AND LINKED WITH A CORRESPONDING ISSUE.

!!! note
    The email address should match the one set in the config.php configuration file
    Make sure that you use the same settings in the MISP Server Settings tool

## 9.06/ Use MISP background workers

### 11/ LIEF Installation
*lief* is required for the Advanced Attachment Handler and requires manual compilation

The installation is explained in section **[3.01](https://misp.github.io/MISP/INSTALL.rhel8/#301-download-misp-code-using-git-in-varwww-directory)**

### 12/ Known Issues
## 12.01/ Workers cannot be started or restarted from the web page
Possible also due to package being installed via SCL, attempting to start workers through the web page will result in error. Worker's can be restarted via the CLI using the following command.
```bash
systemctl restart misp-workers.service
```

!!! note
    No other functions were tested after the conclusion of this install. There may be issue that aren't addressed<br />
    via this guide and will need additional investigation.
