CentOS8＋Apache2.4(SSL)＋PHP7.4 環境構築手順

目次

事前準備

  • CentOS8.1環境構築

  • SSH+rootへ昇格

sudo -i
  • wget python38 インストール （Let's encrypt用のツールcerbotを利用するために必要）
dnf -y install wget python38
  • 好みに合わせてインストール
dnf -y install mlocate vim

構築手順

dnf -y install httpd mod_ssl
systemctl start httpd
  • PHP7.4(現時点の最新版)
dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

dnf -y module install php:remi-7.4

php -v
# --> PHP 7.4.9 が出力
  • Apache用のPHPモジュールインストール
dnf -y module install php74-php
  • Let's Encrypt用ツールcerbotをインストール
cd /tmp
wget https://dl.eff.org/certbot-auto
mv certbot-auto /usr/local/bin/certbot-auto
chown root /usr/local/bin/certbot-auto
chmod 0755 /usr/local/bin/certbot-auto

/usr/local/bin/certbot-auto certonly --webroot -w /var/www/html -d kzyosimo.example.com --email info@example.com

Would you be willing, once your first certificate is successfully issued, to
share your email address with the Electronic Frontier Foundation, a founding
partner of the Let's Encrypt project and the non-profit organization that
develops Certbot? We'd like to send you email about our work encrypting the web,
EFF news, campaigns, and ways to support digital freedom.

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/kzyosimo.example.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/kzyosimo.example.com/privkey.pem
   Your cert will expire on 2020-11-13. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot-auto
   again. To non-interactively renew *all* of your certificates, run
   "certbot-auto renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:
