How To Install Cachet On CentOS 7

Cachet is an open-source status page system written in PHP. Cachet source code is hosted on this GitHub repo. In this article, we will go over the Cachet installation process on CentOS 7 using a PHP, MariaDB, and Nginx software stack.

Requirements

Git
PHP version 5.5.9 or greater
HTTP server with PHP support. This guide will use Nginx.
A supported database: MySQL/MariaDB, PostgreSQL, or SQLite. This guide will use MariaDB.
Composer

Before you begin

Check the CentOS version.

cat /etc/centos-release
# CentOS Linux release 7.5.1804 (Core)

Create a new non-root user account with sudo access and switch to it.

useradd -c "John Doe" johndoe && passwd johndoe
usermod -aG wheel johndoe
su - johndoe

NOTE: Replace johndoe with your username.

Set up the timezone.

timedatectl list-timezones
sudo timedatectl set-timezone 'Region/City'

Ensure that your system is up to date.

sudo yum update -y

Install necessary packages.

sudo yum install -y wget curl vim git

For simplicity, disable SELinux and the firewall.

sudo setenforce 0
sudo systemctl stop firewalld
sudo systemctl disable firewalld

Install PHP and the required PHP extensions

Set up the Webtatic YUM repo.

sudo rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Install PHP and the required PHP extensions.

sudo yum install -y php70w php70w-cli php70w-fpm php70w-common php70w-xml php70w-gd php70w-zip php70w-mbstring php70w-mysql php70w-pgsql php70w-sqlite3 php70w-mcrypt php70w-apc

Check the version.

php --version
# PHP 7.0.30 (cli) (built: Apr 28 2018 08:14:08) ( NTS )

Start and enable PHP-FPM.

sudo systemctl start php-fpm.service
sudo systemctl enable php-fpm.service

Install MariaDB and create a database

Set up the MariDB repo. Run sudo vi /etc/yum.repos.d/MariaDB.repo and populate it with the following.

[mariadb]
name = MariaDB
baseurl = https://yum.mariadb.org/10.2/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Install the MariaDB database server.

sudo yum install -y MariaDB-server MariaDB-client

Check the version.

mysql --version
# mysql Ver 15.1 Distrib 10.2.16-MariaDB, for Linux (x86_64) using readline 5.1

Start and enable MariaDB.

sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Run mysql_secure_installation To improve security and set the password for the MariaDB root user.

sudo mysql_secure_installation

Connect to the MariaDB shell as the root user.

mysql -u root -p
# Enter password:

Create an empty MariaDB database and user for Cachet, and remember the credentials.

CREATE DATABASE dbname;
CREATE DATABASE dbname;
GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
EXIT

Install and configure Nginx

Install Nginx.

sudo yum install -y nginx

Check the version.

nginx -v
# nginx version: nginx/1.12.2

Start and enable Nginx.

sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Configure Nginx. Run sudo vim /etc/nginx/conf.d/cachet.conf and populate the file with the following configuration.

server {
server {
 listen 80;
 listen [::]:80;

 server_name status.example.com; # Check this
 root /var/www/cachet/public; # Check this

 index index.php;

 location / {
   try_files $uri /index.php$is_args$args;
 }

 location ~ \.php$ {
   include fastcgi_params;
   fastcgi_pass 127.0.0.1:9000; # Check this
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   fastcgi_index index.php;
   fastcgi_keep_conn on;
 }
}

Test the configuration.

sudo nginx -t

Reload Nginx.

sudo systemctl reload nginx.service

Install Composer

Install Composer globally.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
sudo mv composer.phar /usr/local/bin/composer

Check the version.

composer --version
# Composer version 1.6.5 2018-05-04 11:44:59

Install Cachet

Create a document root directory.

sudo mkdir -p /var/www/cachet

Change ownership of the /var/www/cachet directory to johndoe.

sudo chown -R johndoe:johndoe /var/www/cachet

Download the Cachet source code with Git and check out the latest tagged release.

cd /var/www/cachet
cd /var/www/cachet
git clone https://github.com/cachethq/Cachet.git .
git tag -l
git checkout v2.3.15

Copy .env.example to the .env file and configure the database, and APP_URL settings in .env.

cp .env.example .env
vim .env

Install dependencies with composer.

composer install --no-dev -o

Set the application key.

php artisan key:generate

Install Cachet.

php artisan app:install

Change ownership of the /var/www/cachet directory to nginx.

sudo chown -R nginx:nginx /var/www/cachet

Run sudo vim /etc/php-fpm.d/www.conf and set the user and group to nginx. Initially, it will be set to Apache.

sudo vim /etc/php-fpm.d/www.conf
# user = nginx
# group = nginx

Restart PHP-FPM.

sudo systemctl restart php-fpm.service

Open your site in a web browser and follow the instructions on the screen to finish the Cachet installation. To access the Cachet dashboard, append /dashboard to your website URL.
