    How to Install Cachet Status Page System on CentOS 7

    Cachet is a beautiful and powerful open source status page system written in PHP that allows you to better communicate downtime and system failures to your customers, teams, and shareholders. The application offers many features, the most important of which are: a powerful JSON API, event reports, metrics, transcription support for event messages, subscriber notifications via email, two-factor authentication. In this tutorial, we will install the Cachet status page system using PHP, Nginx, MySQL, and Composer on the CentOS 7 system.if(typeof __ez_fad_position != ‘undefined’){__ez_fad_position(‘div-gpt-ad-howtoforge_com-box-3-0’)};


    To run Cachet on your CentOS 7 system you will need a couple of things:if(typeof __ez_fad_position != ‘undefined’){__ez_fad_position(‘div-gpt-ad-howtoforge_com-medrectangle-3-0’)};

    • PHP version 7.1 or greater
    • HTTP server with PHP support (eg: Nginx, Apache, Caddy)
    • Composer
    • supported database: MySQL, PostgreSQL or SQLite
    • Git


    • A CentOS 7 operating system.
    • A non-root user with sudo privileges.

    Initial steps

    Check your CentOS version:

    cat /etc/centos-release

    Set up the timezone:

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

    Update your operating system packages (software). This is an important first step because it ensures you have the latest updates and security fixes for your operating system’s default software packages:

    sudo yum upgdate -y

    Install some essential packages that are necessary for basic administration of the CentOS operating system:

    sudo yum install -y curl wget vim git unzip socat bash-completion

    Step 1 – Install PHP

    Setup the Webtatic YUM repo:

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

    Install PHP, as well as the necessary PHP extensions:

    sudo yum install -y php72w-cli php72w-fpm php72w-common php72w-xml php72w-gd php72w-zip php72w-mbstring php72w-mysqlnd php72w-pgsql php72w-sqlite3 php72w-opcache php72w-apcu php72w-json

    To show PHP compiled in modules, you can run:

    php -m

    . . .
    . . .

    Check the PHP version:if(typeof __ez_fad_position != ‘undefined’){__ez_fad_position(‘div-gpt-ad-howtoforge_com-medrectangle-4-0’)};

    php --version

    Start and enable PHP-FPM service:

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

    We can move on to the next step, which is the database installation and setup.

    Step 2 – Install MariaDB and create a database for Cachet

    Cachet supports MySQL, MariaDB, PostgreSQL and SQLite databases. In this tutorial, we will use MariaDB as the database server.

    Create MariaDB 10.2 YUM repository for CentOS:

    sudo vim /etc/yum.repos.d/MariaDB.repo

    Copy and paste the following text into it:

    # MariaDB 10.2 CentOS repository list - created 2017-12-11 23:19 UTC
    # http://downloads.mariadb.org/mariadb/repositories/

    After the file is in place, install MariaDB by running:

    sudo yum install -y MariaDB-server MariaDB-client

    Check the MariaDB version:

    mysql --version
    # mysql  Ver 15.1 Distrib 10.2.21-MariaDB, for Linux (x86_64) using readline 5.1

    Start and enable MariaDB service:

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

    Run mysql_secure installation script to improve MariaDB security and set the password for MariaDB root user:

    sudo mysql_secure_installation

    Answer each of the questions:

    Would you like to setup VALIDATE PASSWORD plugin? N
    New password: your_secure_password
    Re-enter new password: your_secure_password
    Remove anonymous users? [Y/n] Y
    Disallow root login remotely? [Y/n] Y
    Remove test database and access to it? [Y/n] Y
    Reload privilege tables now? [Y/n] Y

    Connect to MariaDB shell as the root user:

    sudo mysql -u root -p
    # Enter password

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

    MariaDB> CREATE DATABASE dbname;
    MariaDB> GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';

    Exit from MariaDB:

    MariaDB> exit

    Replace dbname, username and password with your own names.

    Step 3 – Install Acme.sh client and obtain Let’s Encrypt certificate (optional)

    Securing your website with HTTPS is not necessary, but it is a good practice to secure your site traffic. In order to obtain a TLS certificate from Let’s Encrypt we will use acme.sh client. Acme.sh is a pure UNIX shell software for obtaining TLS certificates from Let’s Encrypt with zero dependencies. 

    Download and install acme.sh:

    sudo su - root
    git clone https://github.com/Neilpang/acme.sh.git
    cd acme.sh 
    ./acme.sh --install --accountemail [email protected]
    source ~/.bashrc
    cd ~

    Check acme.sh version:

    acme.sh --version
    # v2.8.0

    Obtain RSA and ECC/ECDSA certificates for your domain/hostname:

    # RSA 2048
    acme.sh --issue --standalone -d example.com --keylength 2048
    # ECDSA
    acme.sh --issue --standalone -d example.com --keylength ec-256

    If you want fake certificates for testing you can add --staging flag to the above commands.

    After running the above commands, your certificates and keys will be in:

    • For RSA: /home/username/example.com directory.
    • For ECC/ECDSA: /home/username/example.com_ecc directory.

    To list your issued certs you can run:

    acme.sh --list

    Create a directory to store your certs. We will use the /etc/letsencrypt directory.

    mkdir -p /etc/letsecnrypt/example.com
    sudo mkdir -p /etc/letsencrypt/example.com_ecc

    Install/copy certificates to /etc/letsencrypt directory.

    # RSA
    acme.sh --install-cert -d example.com --cert-file /etc/letsencrypt/example.com/cert.pem --key-file /etc/letsencrypt/example.com/private.key --fullchain-file /etc/letsencrypt/example.com/fullchain.pem --reloadcmd "sudo systemctl reload nginx.service"
    acme.sh --install-cert -d example.com --ecc --cert-file /etc/letsencrypt/example.com_ecc/cert.pem --key-file /etc/letsencrypt/example.com_ecc/private.key --fullchain-file /etc/letsencrypt/example.com_ecc/fullchain.pem --reloadcmd "sudo systemctl reload nginx.service"

    All the certificates will be automatically renewed every 60 days.

    After obtaining certs exit from root user and return back to normal sudo user:


    Step 4 – Install and configure NGINX

    Cachet can work fine with many web servers. In this tutorial, we selected NGINXIf you prefer Apache web server over NGINX, visit https://docs.cachethq.io/docs/installing-cachet#section-running-cachet-on-apache to learn more.

    Install NGINX:

    sudo yum install -y nginx

    Check the NGINX version:

    sudo nginx -v

    Start and enable NGINX service:

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

    Configure NGINX for Cachet by running:

    sudo vim /etc/nginx/conf.d/cachet.conf

    And populate the file with the following configuration:

    server {

      listen 80;
      listen [::]:80;
    listen 443 ssl;
    listen [::]:443 ssl;

      server_name status.example.com;

      root /var/www/cachet/public;

      index index.php;

      ssl_certificate /etc/letsencrypt/status.example.com/fullchain.cer;
      ssl_certificate_key /etc/letsencrypt/status.example.com/status.example.com.key;
      ssl_certificate /etc/letsencrypt/status.example.com_ecc/fullchain.cer;
      ssl_certificate_key /etc/letsencrypt/status.example.com_ecc/status.example.com.key;

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

      location ~ \.php$ {
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        fastcgi_keep_conn on;


    Test NGINX configuration:

    sudo nginx -t

    Reload NGINX:

    sudo systemctl reload nginx.service

    Step 5 – Install Composer

    Install Composer, the PHP dependency manager globally:

    php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

    php -r "if (hash_file('sha384', 'composer-setup.php') === '48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5') { 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 Composer version:

    composer --version
    # Composer version 1.8.4 2019-02-11 10:52:10

    Step 6 – Install Cachet

    Create a document root directory where Cachet should reside in:

    sudo mkdir -p /var/www/cachet

    Change ownership of the /var/www/cachet directory to {jour_user}:

    sudo chown -R {your_user}:{your_user} /var/www/cachet

    NOTE: Replace {jour_user} with your initially created non-root user username.

    Navigate to the document root directory:

    cd /var/www/cachet

    Download the Cachet source code with Git:

    git clone -b 2.4 --single-branch https://github.com/cachethq/Cachet.git .

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

    cp .env.example .env
    vim .env

    Install Cachet dependencies with Composer:

    composer install --no-dev -o

    Set up the application key by running:

    php artisan key:generate

    Install Cachet:

    php artisan cachet:install

    Provide the appropriate ownership:

    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, they will be set to apache:

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

    Open your site in a web browser and follow the instructions on the screen to finish Cachet installation.

    Step 7 – Complete the Cachet setup

    Select cache and session drivers and configure mail options:

    Finish the cachet setup

    Configure general site settings like site name, site domain, timezone and language:

    Cachet general settings

    Create an administrative user account:

    Add an admin account

    After that, you should get a message that Cachet has been configured successfully. You can open the Cachet dashboard by pressing the “Go to dashboard” button:

    Cachet has been successfully installed

    Cachet installation and setup has been completed. 

    To access Cachet dashboard append /dashboard to your website URL.
