## Installing PHP 5.6 on Ubuntu 22.04 with CyberPanel

⚠ Warning: PHP 5.6 is deprecated and no longer receives security updates. Running it on Ubuntu 22.04 can introduce security risks. It is recommended to use containers (Docker) or a dedicated virtual machine to isolate PHP 5.6.

✅ Step 1: Install Required Dependencies

Update packages and install dependencies:

sudo apt update && sudo apt upgrade -y
sudo apt install -y software-properties-common
sudo add-apt-repository -y ppa:ondrej/php
sudo apt update

---

✅ Step 2: Install PHP 5.6 and Required Extensions

sudo apt install -y php5.6 php5.6-cli php5.6-fpm php5.6-mysql php5.6-xml \
php5.6-mbstring php5.6-curl php5.6-zip php5.6-gd php5.6-soap php5.6-bcmath \
php5.6-intl php5.6-readline

Verify installation:

php5.6 -v

Expected output:

PHP 5.6.x (cli) (built: ...)
Zend Engine v2.6.0

---

✅ Step 3: Configure PHP 5.6 for CyberPanel

1. Check existing PHP versions in CyberPanel

ls /usr/local/lsws/lsphp*

2. Create a directory for PHP 5.6

sudo mkdir -p /usr/local/lsws/lsphp56

3. Symlink PHP 5.6 binaries

sudo ln -s /usr/bin/php5.6 /usr/local/lsws/lsphp56/bin/php
sudo ln -s /usr/sbin/php5.6-fpm /usr/local/lsws/lsphp56/bin/php-fpm

4. Edit CyberPanel's LiteSpeed configuration

sudo nano /usr/local/lsws/conf/httpd_config.conf

Add this block:

extprocessor lsphp56 {
    type                    lsapi
    address                 uds://tmp/lshttpd/lsphp56.sock
    maxConns                10
    env                     PHP_LSAPI_CHILDREN=10
    env                     LSAPI_AVOID_FORK=200M
    initTimeout             60
    retryTimeout            0
    persistConn             1
    pcKeepAliveTimeout      60
    respBuffer              0
    autoStart               1
    path                    /usr/local/lsws/lsphp56/bin/lsphp
    backlog                 100
}

Save and exit (CTRL + X, then Y, then Enter).

---

✅ Step 4: Restart Services

sudo systemctl restart lsws
sudo systemctl restart php5.6-fpm

---

✅ Step 5: Add PHP 5.6 to CyberPanel

1. Log in to CyberPanel.
2. Navigate to Websites → List Websites.
3. Select the domain requiring PHP 5.6.
4. Click Manage.
5. Scroll to PHP Version, manually enter lsphp56, and save.
6. Restart the website.

---

✅ Step 6: Test PHP 5.6

Create a test file:

sudo nano /home/example.com/public_html/info.php

Add this content:

<?php
phpinfo();
?>

Save and exit.

Now, visit:

http://example.com/info.php

You should see the PHP 5.6 information page.

🎯 Alternative: Use Docker for Security

If security is a concern, use a Docker container:

docker run -d --name php56 -p 9000:9000 php:5.6-fpm

Then, configure CyberPanel to use localhost:9000 as the external PHP processor.

---

🎯 Final Notes

• If possible, migrate to a newer PHP version.
• If PHP 5.6 is required, isolate it in a container or VM.
• If using it directly, disable public access to PHP 5.6 applications.

🚀 Now PHP 5.6 is installed and configured on CyberPanel with Ubuntu 22.04!
