centos stream 9 に nginx と php8.1 をインストール

2021/12/17現在、 centos stream 9は snapd を インストールできないみたい。
もう少し待ってから使ったほうが良い。

まずは鍵認証までOKという前提

yum update
sudo timedatectl set-timezone Asia/Tokyo

selinux を オフ

grubby --update-kernel ALL --args selinux=0
shutdown -r now

epel , remi を それぞれ追加

dnf config-manager --set-enabled crb
dnf install https://dl.fedoraproject.org/pub/epel/9/Everything/x86_64/Packages/e/epel-release-9-2.el9.noarch.rpm
dnf install https://dl.fedoraproject.org/pub/epel/9/Everything/x86_64/Packages/e/epel-next-release-9-2.el9.noarch.rpm

dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm
dnf config-manager --set-enabled remi

nginx の リポジトリを追加

vi /etc/yum.repos.d/nginx.repo

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
enabled=0
gpgcheck=0

nginx インストール

yum install nginx
nginx -v
//nginx version: nginx/1.20.1 ok

nginx の設定ファイル

vim /etc/nginx/nginx.conf

user  nginx;
worker_processes  auto;
worker_rlimit_nofile 100000;

error_log  /var/log/nginx/error.log warn;

    include /etc/nginx/conf.d/*.conf;
}

php8 インストール

//まずはリスト表示
sudo dnf module list reset php -y

//8.1 を有効に
sudo dnf module enable php:remi-8.1

//php と、その他必要そうなファイルを一気にインスコ

sudo dnf install php php-cli php-fpm php-curl php-mysqlnd php-gd php-opcache php-zip php-intl php-common php-bcmath php-imap php-imagick php-xmlrpc php-json php-readline php-memcached php-redis php-mbstring php-apcu php-xml

//確認

php -v

www.conf を書き換え

vim /etc/php-fpm.d/www.conf

#user = apache 
user = nginx

#group = apache
group = nginx

php-fpm再起動

sudo systemctl restart php-fpm

vim /var/www/html/yamada/index.php

<?php

    phpinfo();

?>

vim /etc/nginx/conf.d/default.conf

server {
    listen 80;
    server_name yourdomain.net;
    root   /var/www/html/yamada/;
    index index.php index.html index.htm;



         location ~ \.php$ {

       fastcgi_pass   unix:/var/run/php-fpm/www.sock;

       fastcgi_index  index.php;

       fastcgi_param  SCRIPT_FILENAME /var/www/html/yamada$fastcgi_script_name;
        include        fastcgi_params;

 }



}

sudo nginx -t
sudo systemctl restart nginx

//ついでに自動起動設定も
sudo systemctl enable nginx
sudo systemctl enable php-fpm

firewall も開けよう

firewall-cmd --add-service=https --zone=public --permanent
firewall-cmd --add-service=http --zone=public --permanent
firewall-cmd --reload

これでサーバーのIPアドレスにアクセスして、phpinfoが表示されればOK!
