教你最快速度安装php8.2套件（ubuntu 20.04 focal）

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

首先必须 apt update
安装 vim

vim /etc/apt/sources.list
内容如下，就是搞阿里云镜像。但是http的，被我改的。不搞无法更新。
deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

然后
apt update

apt install -y --reinstall ca-certificates

现在，再把阿里云镜像库中的 http 改成标准的 https，
vim /etc/apt/sources.list

deb https://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

# deb https://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
然后。再次
apt update

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

上面的命令需要选择多个选项。选亚洲 asia。选上海 shanghai

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

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/

vim /etc/environment

export COMPOSER_ALLOW_SUPERUSER=1

source /etc/environment

curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor | tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg

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

改php-fpm 配置。
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


修改 /etc/nginx/nginx.conf
第一行 
user  www-data;

然后，
rm -f /etc/nginx/conf.d/default.conf
vi /etc/nginx/conf.d/default.conf
/etc/nginx/conf.d/default.conf 文件内容如下

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;

    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;
    }
}

vi /usr/share/nginx/html/1.php

<?php
phpinfo();

/etc/init.d/nginx start
/etc/init.d/php8.2-fpm start

curl localhost/1.php
# 如果能看到很多的大量输出，说明php和nginx正确安装了。

apt install mysql-server-8.0 mysql-client-8.0



# 查看初始密码：

# 这句话查看用户的加密方式。

curl -fsSL https://packages.redis.io/gpg | gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg
