INSTALLATION INSTRUCTIONS for RHEL 8.x and partially Fedora Server 30

-1/ Installer and Manual install instructions

Make sure you are reading the parsed version of this Document. When in doubt click here.

!!! warning In the future, to install MISP on a fresh RHEL 8 install all you need to do is:

```bash
# Please check the installer options first to make the best choice for your install
wget -O /tmp/INSTALL.sh https://raw.githubusercontent.com/MISP/MISP/2.4/INSTALL/INSTALL.sh
bash /tmp/INSTALL.sh

# This will install MISP Core
wget -O /tmp/INSTALL.sh https://raw.githubusercontent.com/MISP/MISP/2.4/INSTALL/INSTALL.sh
bash /tmp/INSTALL.sh -c
```
**The above does NOT work yet**

0/ Overview and Assumptions

{!generic/community.md!}

{!generic/rhelVScentos.md!}

!!! warning The core MISP team cannot 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.

This document details the steps to install MISP on Red Hat Enterprise Linux 8.x (RHEL 8.x).

This document details the steps to install MISP on Red Hat Enterprise Linux 8.x (RHEL 8.x) and CentOS 8.x. At time of this writing it was tested on versions 8.0 for RHEL. This is a joint RHEL/CentOS 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 details some shortcomings.

{!generic/globalVariables.md!}

!!! note For fresh installs the following tips might be handy.
Allow ssh to pass the firewall on the CLI bash firewall-cmd --zone=public --add-port=22/tcp --permanent firewall-cmd --reload
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/CentOS installation, configure IP address to connect automatically.

1.2/ Configure system hostname (if not done during install)

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

# <snippet-begin 0_RHEL_register.sh>
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, extras and Software Collections (SCL) repos

# <snippet-begin 0_RHEL_SCL.sh>
# To be confirmed, no access to RHSCL
sudo subscription-manager refresh 
sudo subscription-manager repos --enable rhel-8-server-optional-rpms
sudo subscription-manager repos --enable rhel-8-server-extras-rpms
sudo subscription-manager repos --enable rhel-server-rhscl-8-rpms
# <snippet-end 0_RHEL_SCL.sh>

1.5a/ Install the deltarpm package to help reduce download size when installing updates (optional)

sudo yum install drpm -y

1.5.b/ Install vim (optional)

# Because vim is just so practical
sudo yum install vim -y

1.5/ Update the system and reboot

# <snippet-begin 0_yum-update.sh>
sudo yum update -y
# <snippet-end 0_yum-update.sh>

1.6/ [RHEL] Install the EPEL repo

!!! note There is no epel-releas-latest-8 yet, but the RHEL 7 seems to work for testing.

# <snippet-begin 0_RHEL_EPEL.sh>
sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm -y
# <snippet-end 0_RHEL_EPEL.sh>

2/ Dependencies

!!! note This guide installs PHP 7.2 from SCL

!!! warning PHP 5.6 and 7.0 aren't supported since December 2018. Please update accordingly. In the future only PHP7 will be supported.

2.01/ Install some base system dependencies

# <snippet-begin 0_yumInstallCoreDeps.sh>
yumInstallCoreDeps () {
  # Install the dependencies:
  sudo yum install @httpd -y
  sudo yum install gcc git zip \
                   httpd \
                   mod_ssl \
                   redis \
                   mariadb \
                   mariadb-server \
                   python3-devel python3-pip python3-virtualenv \
                   python3-policycoreutils \
                   libxslt-devel zlib-devel ssdeep-devel -y
  sudo alternatives --set python /usr/bin/python3

  # Enable and start redis
  sudo systemctl enable --now redis.service

  PHP_INI=/etc/php.ini
  sudo yum install php php-fpm php-devel \
       php-mysqlnd \
       php-mbstring \
       php-xml \
       php-bcmath \
       php-opcache \
       php-json \
       php-gd -y
}
# <snippet-end 0_yumInstallCoreDeps.sh>

!!! notice MISP 2.4 requires PHP 5.6 as a minimum, we need a higher version than base RHEL provides.
This guide installs PHP 7.2

!!! notice If we want to use httpd from RHEL base we can use the rh-php72-php-fpm service instead

2.05/ Start the PHP FPM service and enable to start on boot

sudo systemctl enable --now php-fpm.service

# <snippet-begin 0_yumInstallHaveged.sh>
# GPG needs lots of entropy, haveged provides entropy
# /!\ Only do this if you're not running rngd to provide randomness and your kernel randomness is not sufficient.
sudo yum install haveged -y
sudo systemctl enable --now haveged.service
# <snippet-end 0_yumInstallHaveged.sh>

11/ LIEF Installation

lief is required for the Advanced Attachment Handler and requires manual compilation

The installation is explained in section 3.01

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.

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
via this guide and will need additional investigation.
