INSTALLATION INSTRUCTIONS for RHEL 8.x based distros

-2/ RHEL8/Rocky8.4/Rocky8.5/Fedora34/Fedora35 - status

!!! notice Tested fully working without SELinux by @SteveClement on 20210702

!!! notice TODO: Fix SELinux permissions, pull-requests welcome.

{!generic/manual-install-notes.md!}

!!! notice If the next line is [!generic/community.md!]() click here.

{!generic/community.md!}

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] Source[1] Consider using Rocky Linux CentOS 8 NetInstallURL

{!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 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/Rocky 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>
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)

# <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)

sudo dnf install drpm -y

1.5.b/ Install vim (optional)

# 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)

# 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

# <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

# <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. Please update accordingly. In the future only PHP7 will be supported.

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:

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.
