# INSTALLATION INSTRUCTIONS for RHEL 7.x and CentOS 7.x
-------------------------

### -1/ Installer and Manual install instructions

Make sure you are reading the parsed version of this Document. When in doubt [click here](https://misp.github.io/MISP/INSTALL.rhel7/).

!!! warning
    In the **future**, to install MISP on a fresh RHEL 7 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/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.

!!! notice
    Maintenance for CentOS 7 will end on: June 30th, 2024 [Source[0]](https://wiki.centos.org/About/Product) [Source[1]](https://linuxlifecycle.com/)
    CentOS 7-1908 [NetInstallURL](http://mirror.centos.org/centos/7/os/x86_64/)

This document details the steps to install MISP on Red Hat Enterprise Linux 7.x (RHEL 7.x) and CentOS 7.x.
At time of this writing it was tested on versions 7.6 for both.
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](https://github.com/MISP/MISP/issues/4084) details some shortcomings.

{!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/CentOS 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>
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
```bash
# <snippet-begin 0_RHEL_SCL.sh>
enableReposRHEL () {
  sudo subscription-manager refresh
  sudo subscription-manager repos --enable rhel-7-server-optional-rpms
  sudo subscription-manager repos --enable rhel-7-server-extras-rpms
  sudo subscription-manager repos --enable rhel-server-rhscl-7-rpms
}
# <snippet-end 0_RHEL_SCL.sh>
```

## 1.4c/ **[CentOS]** Enable EPEL for additional dependencies
```bash
# <snippet-begin 0_CentOS_EPEL.sh>
centosEPEL () {
  # We need some packages from the Extra Packages for Enterprise Linux repository
  sudo yum install epel-release -y

  # Since MISP 2.4 PHP 5.5 is a minimal requirement, so we need a newer version than CentOS base provides
  # Software Collections is a way do to this, see https://wiki.centos.org/AdditionalResources/Repositories/SCL
  sudo yum install centos-release-scl -y
}
# <snippet-end 0_CentOS_EPEL.sh>
```

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

## 1.5.b/ Install vim (optional)
```bash
# Because (neo)vim is just so practical
sudo yum install neovim -y
```

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

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

## 1.6/ **[RHEL]** Install the EPEL repo
```bash
# <snippet-begin 0_RHEL_EPEL.sh>
enableEPEL () {
  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](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
```bash
# <snippet-begin 0_yumInstallCoreDeps.sh>
yumInstallCoreDeps () {
  # Install the dependencies:
  sudo yum install gcc git zip rh-git218 \
                   httpd24 \
                   mod_ssl \
                   rh-redis32 \
                   rh-mariadb102 \
                   libxslt-devel zlib-devel ssdeep-devel -y

  # Enable and start redis
  sudo systemctl enable --now rh-redis32-redis.service

  WWW_USER="apache"
  SUDO_WWW="sudo -H -u $WWW_USER"
  RUN_PHP="/usr/bin/scl enable rh-php72"
  PHP_INI="/etc/opt/rh/rh-php72/php.ini"
  # Install PHP 7.2 from SCL, see https://www.softwarecollections.org/en/scls/rhscl/rh-php72/
  sudo yum install rh-php72 rh-php72-php-fpm rh-php72-php-devel \
                   rh-php72-php-mysqlnd \
                   rh-php72-php-mbstring \
                   rh-php72-php-xml \
                   rh-php72-php-bcmath \
                   rh-php72-php-opcache \
                   rh-php72-php-gd -y

  # Python 3.6 is now available in RHEL 7.7 base
  sudo yum install python3 python3-devel -y

  sudo systemctl enable --now rh-php72-php-fpm.service
}
# <snippet-end 0_yumInstallCoreDeps.sh>
```

!!! notice
    $RUN_PHP makes php available for you if using rh-php72. e.g: sudo $RUN_PHP "pear list | grep Crypt_GPG"

```bash
# <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>
```

### 3/ MISP code

### 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

}
# <snippet-end 1_installCake_RHEL.sh>
```

### 5/ Set file permissions
```bash
# <snippet-begin 2_permissions_RHEL.sh>
# Main function to fix permissions to something sane
permissions_RHEL () {
  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/custom
}
# <snippet-end 2_permissions_RHEL.sh>
```

### 6/ Create database and user

## 6.01/ Set database to listen on localhost only
```bash
# <snippet-begin 1_prepareDB_RHEL.sh>
prepareDB_RHEL () {
  RUN_MYSQL="/usr/bin/scl enable rh-mariadb102"
  # Enable, start and secure your mysql database server

### 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.

### 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
  # Impact of the following: ?!?!?!!?111
  ##sudo restorecon -R $PATH_TO_MISP

  # Allow logrotate to read /var/www
  sudo checkmodule -M -m -o /tmp/misplogrotate.mod $PATH_TO_MISP/INSTALL/misplogrotate.te

  # Important! Change the salt key in $PATH_TO_MISP/app/Config/config.php
  # The admin user account will be generated on the first login, make sure that the salt is changed before you create that user
  # If you forget to do this step, and you are still dealing with a fresh installation, just alter the salt,
  # delete the user from mysql and log in again using the default admin credentials (admin@admin.test / admin)

!!! 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.rhel7/#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.
