ubuntu 20.04 安装php8.0

apt-get安装

# 追加一个PHP相关的存储库
sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update

# 安装php8系列版本

sudo apt install php8.*
sudo apt install libapache2-mod-php8.* #与apache2交互的模块
sudo a2enmod proxy_fcgi setenvif
sudo a2enconf php8.*-fpm

编译安装（以下是一个安装脚本）

 

#! /bin/bash

read -p "请输入安装路径:" installdir

if [ ! $installdir ]
then
echo "安装路径不得为空！";
exit -1
fi

#rm -rf $installdir
source=/etc/apt/sources.list


if [ `grep -c "deb http://mirrors.aliyun.com/ubuntu/" $source` -eq '0' ]
then
    mv $source /etc/apt/sources.list.bak
    touch $source
elif [ ! -e "$source" ]
then
    touch $source
fi

chmod 777 $source

# 写入阿里巴巴镜像
if [ `grep -c "deb http://mirrors.aliyun.com/ubuntu/" $source` -eq '0' ]
then
cat > "$source" << EOF

then

编译安装是没有pecl跟pear的需要手动安装

wget http://pear.php.net/go-pear.phar -O go-pear.php
php go-pear.php
