Ubuntu 16.04 PHP升级为PHP 7.4

环境：

Ubuntu 16.04.6 LTS
PHP 5.6.40
Nginx

目标：

将PHP版本升级为7.4，以应对WordPress提示PHP版本过时问题。

升级步骤：

将repos.zend.com GPG密钥添加到您的apt密钥链中

curl -s https://repos.zend.com/zend.key | gpg --dearmor > /usr/share/keyrings/zend.gpg

将repos.zend.com存储库添加到您的apt源列表中

sudo echo "deb [signed-by=/usr/share/keyrings/zend.gpg] https://repos.zend.com/zendphp/deb_ubuntu1604/ zendphp non-free" > /etc/apt/sources.list.d/zendphp.list

更新您的程序包来源

sudo apt-get update

如果有报错，则将第2步的命令改为

sudo echo "deb [arch=amd64 signed-by=/usr/share/keyrings/zend.gpg] https://repos.zend.com/zendphp/deb_ubuntu1604/ zendphp non-free" > /etc/apt/sources.list.d/zendphp.list

然后再去执行

sudo apt-get update

如果报了如下错：

E: Failed to fetch https://repos.zend.com/zendphp/deb_ubuntu1604/pool/libapache2-mod-php7.4-zend_7.4.33.2-1_amd64.deb  401  Unauthorized

E: Failed to fetch https://repos.zend.com/zendphp/deb_ubuntu1604/pool/php7.4-zend_7.4.33.2-1_all.deb  401  Unauthorized

则需要去https://www.zend.com/products/zendphp-enterprise/trial 注册一个账号，

然后执行如下命令：

 sudo \
echo "machine repos.zend.com login {LOGIN_OR_ORDER_ID} password {PASSWORD}" \
> /etc/apt/auth.conf.d/zendphp.conf

注：{LOGIN_OR_ORDER_ID}和{PASSWORD}换成实际的，最终的conf文件里没有{}

安装PHP程序包

sudo apt-get install php7.4-zend-fpm
sudo update-alternatives --set php /usr/bin/php7.4-zend
sudo apt-get install php7.4-zend-mysql
