Below is my attempt at documenting the steps that I performed to successfully install Cachet on RHEL 7. I had to use not only the official installation guide from Cachet, but several other guides provided by people who have successfully installed it on Ubuntu and Centos. Here for reference are the guides I used to install Cachet:
Install and Configure MariaDB
yum install mariadb
systemctl enable mariadb
systemctl start mariadb
#Secure the MariaDB installation and set root password
mysql_secure_installation
#Create cachet database
mysql -e "create database cachet"
#Create cachet user
mysql -e "create user 'cachet'@'localhost' identified by 'CACHET_USER_PASSWORD'"
mysql -e "grant all privileges on cachet.* to 'cachet'@'localhost'"
mysql -e "flush privileges"
Configure Additional Repositories
Enable ‘optional’ repository (rhel-7-server-optional-rpms) and the ‘extras’ repository (rhel-7-server-extras-rpms).
Do this by modifying the /etc/yum.repos.d/redhat.repo file
Look for the [rhel-7-server-optional-rpms] and [rhel-7-server-extras-rpms] sections
modify the enabled = 0 to enabled = 1 for both repositories
Install the Extra Packages for Enterprise Linux
Now install EPEL by running
yum install epel-release
Install the Remi Repository for PHP packages that are not available with the default system repositories.
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
Install the Cachet package dependencies
yum --enablerepo=remi,remi-php56 install php-fpm php-common php-mcrypt php-mbstring php-apcu php-xml php-pdo php-intl php-mysql php-cli php-gd git
PHP configuration
#verify installed php version(s)
rpm -qa | grep -i php
#Enable php-fpm to run at startup
systemctl enable php-fpm
#Start php-fpm
systemctl start php-fpm
By default php-fpm will listen to 127.0.0.1:9000. The listen directive “127.0.0.1:9000” will be used in the apache virtualhost config detailed below. If you want to change this default port, modify the following file:
vi /etc/php-fpm.d/www.conf
Install Composer
curl -sS https://getcomposer.org/installer | php -- --install-dir=/bin --filename=composer
Install Cachet
Clone the Cachet Repository
cd /var/www/
git clone https://github.com/cachethq/Cachet.git
cd Cachet/
git tag -l
git checkout v2.3.9
cp -v .env.example .env
Modify the Cachet configuration file to look like the following
[user@myserver Cachet]# cat .env
APP_ENV=local
APP_DEBUG=false
APP_URL=http://myserver.mydomain.com
APP_KEY=base64:myAPPKEY448574944755NotReal383857kdhf=
DB_DRIVER=mysql
DB_HOST=127.0.0.1
DB_DATABASE=cachet
DB_USERNAME=cachet
DB_PASSWORD=myDBpassword
CACHE_DRIVER=apc
SESSION_DRIVER=apc
QUEUE_DRIVER=database
MAIL_DRIVER=smtp
MAIL_HOST=mymailserver.mydomain.com
MAIL_PORT=25
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ADDRESS=myserver@mydomain.com
Set apache user:group permissions for Cachet
chown -R apache:apache /var/www/Cachet/
Compose the site
cd /var/www/Cachet
composer install --no-dev -o
Generate a Application Key used for encryption
php artisan key:generate
Run the installer that seeds the database
php artisan app:install
Configuring Apache
Install and configure Apache service
yum install httpd
systemctl enable httpd
systemctl start httpd
Create a virtualhost configuration file called vhost.conf within the /etc/httpd/conf.d/ directory. It should look like the following:
[user@myserver Cachet]# cat /etc/httpd/conf.d/vhost.conf
<VirtualHost *:80>
ServerName myserver.mydomain.com
ServerAlias myserver.mydomain.com
DocumentRoot "/var/www/Cachet/public"
<Directory "/var/www/Cachet/public">
Require all granted
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
<FilesMatch \.php$>
SetHandler "proxy:fcgi://127.0.0.1:9000"
</FilesMatch>
</VirtualHost>
Notice the <FilesMatch \.php$> directive. This was required in order to get php working within apache. Otherwise, you will get an error page when navigating to the cachet dashboard page.
I also modified the /etc/httpd/conf/httpd.conf file and included the DirectoryIndex index.php option.
<IfModule dir_module>
DirectoryIndex index.html index.php
</IfModule>
Test Cachet Status Page
navigate to the following address in your browser: http://yourcachetserver.yourdomain.com
You should be redirected to the /setup page
Congratulations!!
