快如闪电的安装php（centos8）

本文只考虑centos8

remi是一个php安装仓库。是rpm包。

用了国内镜像会速度极快，下载包的速度：3MB/秒，惊人的快！

无论docker还是centos环境都非常的快！！

首先，安装阿里的 centos 仓库。

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.reporm -f  /etc/yum.repos.d/CentOS-centosplus.reporm -f  /etc/yum.repos.d/CentOS-PowerTools.reporm -f  /etc/yum.repos.d/CentOS-Extras.reporm -f  /etc/yum.repos.d/CentOS-AppStream.repo
dnf makecache
dnf repolist

安装阿里的 epel 仓库。

dnf install -y epel-releasesed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*
dnf makecache
dnf repolist

安装阿里的 remi 的仓库

dnf install -y https://mirrors.aliyun.com/remi/enterprise/remi-release-8.rpmsed -i  's/https*:\/\/rpms.remirepo.net/https:\/\/mirrors.aliyun.com\/remi/g'  /etc/yum.repos.d/remi*sed -i 's/#baseurl/baseurl/g' /etc/yum.repos.d/remi*

快如闪电的最关键是下一句，清除镜像列表！！否则又去读取国外的镜像了。

立即学习“PHP免费学习笔记（深入）”；

sed -i 's|^mirrorlist|#mirrorlist|' /etc/yum.repos.d/remi*

dnf makecache
dnf repolist

安装 php

dnf install -y yum-utils

dnf install -y php74 php74-php-devel  php74-php-fpm  php74-php-mbstring php74-php-memcache php74-php-memcached php74-php-redis  php74-php-mysqlnd  php74-php-pdo  php74-php-bcmath php74-php-xml php74-php-gd php74-php-gmp php74-php-igbinary php74-php-imagick   php74-php-mcrypt  php74-php-pdo_mysql php74-php-posix php74-php-simplexml  php74-php-opcache php74-php-xsl php74-php-xmlwriter php74-php-xmlreader php74-php-swoole php74-php-zip php74-php-phalcon  php74-php-yaml php74-php-yar php74-php-yaf php74-php-uuid

体验到快如闪电的速度了吧！

最后安装阿里的 composer 镜像源

ln -s /usr/bin/php74 /usr/bin/phpcurl -o /usr/local/bin/composer https://mirrors.aliyun.com/composer/composer.pharchmod +x /usr/local/bin/composer

注意观察，确认安装成功，且大版本是2.0

composer -V

立刻设置composer 的镜像源为阿里

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

安装 nginx

cat>/etc/yum.repos.d/nginx.repo<<EOF
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/\$releasever/\$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key

EOFdnf install -y nginx
nginx -v
systemctl enable nginx
