本篇文章给大家带来了关于php8.2的相关知识，其中主要介绍了教大家怎么快速安装php8.2套件？到底有多快呢？大概可能20分钟左右...下面一起来看一下，希望对大家有帮助。
快速安装php8.2套件（ubuntu 20.04 focal）
到底有多快？我这边尝试的结果是总共大约 20 分钟左右（不含操作系统）。
另外，同样是我的电脑，同样阿里云镜像库，装 centos 系统各类软件含 php 就很快，但装这个 ubuntu 就比较慢，原因不太清楚（可能的一个原因是因为 ubuntu 用的人太多，阿里限制了源的下载速率来稍微省点钱。）。

首先，安装阿里的 仓库
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
安装 php 8
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
执行上面这些命令，大约 15 分钟左右，主要耗时就是这里。
安装阿里的 composer 镜像源
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/
使用 root 身份执行 composer 命令，会提示输入 yes ，挺麻烦，则
vim /etc/environment
文字
export COMPOSER_ALLOW_SUPERUSER=1
然后
source /etc/environment
安装 nginx 并整合 php-fpm 服务
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;
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;
}
}添加一个 php 文件如下：
vi /usr/share/nginx/html/1.php <?php phpinfo();
启动 php-fpm 和 nginx 并验证安装正确
/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。
安装 mysql 8
apt install mysql-server-8.0 mysql-client-8.0 # 查看初始密码： grep 'temporary password' /var/log/mysqld.log # 用查看到的密码进入mysql 的 shell mysql -uroot -p
下面，整套设置新用户流程，先改初始，再加新用户并授权，再删除老用户。
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;
退出 shell，重新进入。
现在就可以直接进入 shell
mysql -uroot -proot1234 # 这句话查看用户的加密方式。 select user, host, plugin from mysql.user\G; # plugin: caching_sha2_password 表示老的MySQL客户端无法连接！
安装 redis 6 以及其他常用库
说明，安装 redis 7 需要下二进制包编译，坚决不编译，所以没搞。
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
注意和上面版本不同，如想安装 redis5
如想redis5，啥源都不需要，直接
apt install redis-server
总结
感谢阿里云镜像库，但是速度不是太快。
