Quick Guide to Installing PHP 8.2 Stack on Ubuntu 20.04 Using Alibaba Cloud Mirrors

The article presents a step‑by‑step procedure for rapidly installing a complete PHP 8.2 development stack (PHP, Nginx, MySQL, Redis, Composer, etc.) on an Ubuntu 20.04 (Focal) server, using Alibaba Cloud mirrors to speed up package downloads.

Software versions used :

ubuntu 20.04
php 8.2.1
nginx 1.22.1
mysql 8.0.31
redis 7.0.7
git 2.24.4

1. Configure Alibaba apt repositories

apt update
vim /etc/apt/sources.list   # replace with Alibaba http sources
# example entry
deb http://mirrors.aliyun.com/ubuntu focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu focal main restricted universe multiverse
# repeat for security, updates, backports
apt update
apt install -y --reinstall ca-certificates

After editing, switch the URLs to https and run apt update again.

2. Install PHP 8 and extensions

apt install -y gnupg gosu curl ca-certificates zip unzip git supervisor sqlite3 libcap2-bin libpng-dev python2 dnsutils systemd gnupg2 lsb-release ubuntu-keyring
curl -sS 'https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x14aa40ec0831756756d7f66c4f4ea0aae5267a6c' | gpg --dearmor | tee /usr/share/keyrings/ppa_ondrej_php.gpg > /dev/null
echo "deb [signed-by=/usr/share/keyrings/ppa_ondrej_php.gpg] https://ppa.launchpadcontent.net/ondrej/php/ubuntu focal main" > /etc/apt/sources.list.d/ppa_ondrej_php.list
apt-get update
apt-get install -y php8.2-cli php8.2-dev php8.2-pgsql php8.2-sqlite3 php8.2-gd php8.2-curl php8.2-imap php8.2-mysql php8.2-mbstring php8.2-xml php8.2-zip php8.2-bcmath php8.2-soap php8.2-intl php8.2-readline php8.2-ldap php8.2-msgpack php8.2-igbinary php8.2-redis php8.2-swoole php8.2-memcached php8.2-pcov php8.2-fpm php8.2-gmp php8.2-imagick php8.2-mcrypt php8.2-uuid php8.2-yaml

The installation typically takes about fifteen minutes.

3. Configure Composer to use Alibaba mirror

curl -o /usr/local/bin/composer https://mirrors.aliyun.com/composer/composer.phar
chmod +x /usr/local/bin/composer
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

To suppress the "yes" prompt when running Composer as root, add the environment variable:

echo "export COMPOSER_ALLOW_SUPERUSER=1" >> /etc/environment
source /etc/environment

4. Install Nginx and link it with php‑fpm

curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor | tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/ubuntu $(lsb_release -cs) nginx" | tee /etc/apt/sources.list.d/nginx.list
apt update
apt install nginx
sed -i 's/listen = \/run\/php\/php8.2-fpm.sock/listen = 127.0.0.1:9000/g' /etc/php/8.2/fpm/pool.d/www.conf
# modify /etc/nginx/nginx.conf to set user www-data;
rm -f /etc/nginx/conf.d/default.conf
cat > /etc/nginx/conf.d/default.conf <<'EOF'
server {
    listen 80;
    server_name localhost;
    charset utf-8;
    access_log /var/log/nginx/host.access.log main;
    root /usr/share/nginx/html;
    index index.php index.html index.htm;
    error_page 404 500 502 503 504 /50x.html;
    location = /50x.html { root /usr/share/nginx/html; }
    location / { try_files $uri $uri/ /index.php?$query_string; }
    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }
}
EOF
/etc/init.d/nginx start
/etc/init.d/php8.2-fpm start
curl localhost/1.php   # should display phpinfo()

5. Install MySQL 8 and configure a new root user

apt install mysql-server-8.0 mysql-client-8.0
grep 'temporary password' /var/log/mysqld.log   # obtain initial password
mysql -uroot -p   # login with temporary password
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'tb4Wn3BthR.';
flush privileges;
CREATE USER 'root'@'%' IDENTIFIED BY 'root1234';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'root1234';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
DROP USER root@localhost;
flush privileges;
mysql -uroot -proot1234   # verify login
SELECT user, host, plugin FROM mysql.user\G;

6. Install Redis 6 (stack) and optionally Redis 5

curl -fsSL https://packages.redis.io/gpg | gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/redis-archive-keyring.gpg] https://packages.redis.io/deb $(lsb_release -cs) main" | tee /etc/apt/sources.list.d/redis.list
apt-get update
apt-get install redis-stack-server   # installs Redis 6
# For Redis 5 simply:
# apt install redis-server

The guide concludes by noting that Alibaba Cloud mirrors speed up most downloads, though Ubuntu packages may still be slower due to bandwidth limits.
