Ubuntu 安装 PHP 和 Composer

本文根据 Install / Upgrade to PHP 7.3、Download Composer、Packagist 中国全量镜像、ppa:ondrej/php FAQs 实践并记录。

添加 PPA

sudo apt install -y software-properties-common
sudo add-apt-repository -y ppa:ondrej/php
sudo apt update

安装 PHP

PHP FPM

sudo apt install -y php7.3-fpm

• 软件包 php7.3、php-common、php7.3-cli、php7.3-common、php7.3-json、php7.3-opcache、php7.3-readline 会被自动安装。
• 不能在 php7.3 后安装 php7.3-fpm，否则会和 libapache2-mod-php7.3 冲突。
• 安装成功后 php7.3-fpm 会自动启动，并自动设置为开机启动。

PHP 拓展

sudo apt install -y php7.3-bcmath php7.3-curl php7.3-gd php7.3-mbstring php7.3-mysql php7.3-xml php7.3-zip

配置 PHP

TODO：进一步理解和优化配置。

# PHP CLI
sudo sed -i 's/display_errors = .*/display_errors = On/' /etc/php/7.3/cli/php.ini
sudo sed -i 's/error_reporting = .*/error_reporting = E_ALL/' /etc/php/7.3/cli/php.ini
sudo sed -i 's/memory_limit = .*/memory_limit = 512M/' /etc/php/7.3/cli/php.ini
sudo sed -i 's/;date.timezone.*/date.timezone = UTC/' /etc/php/7.3/cli/php.ini

# PHP FPM
sudo sed -i 's/error_reporting = .*/error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED/' /etc/php/7.3/fpm/php.ini
sudo sed -i 's/memory_limit = .*/memory_limit = 512M/' /etc/php/7.3/fpm/php.ini
sudo sed -i 's/upload_max_filesize = .*/upload_max_filesize = 50M/' /etc/php/7.3/fpm/php.ini
sudo sed -i 's/post_max_size = .*/post_max_size = 50M/' /etc/php/7.3/fpm/php.ini
sudo sed -i 's/;date.timezone.*/date.timezone = UTC/' /etc/php/7.3/fpm/php.ini

# PHP Pools
sudo sed -i 's/user = www-data/user = www/' /etc/php/7.3/fpm/pool.d/www.conf
sudo sed -i 's/group = www-data/group = www/' /etc/php/7.3/fpm/pool.d/www.conf
sudo sed -i 's/listen =.*/listen = 127.0.0.1:9000/' /etc/php/7.3/fpm/pool.d/www.conf
sudo sed -i 's/listen.owner.*/listen.owner = www/' /etc/php/7.3/fpm/pool.d/www.conf
sudo sed -i 's/listen.group.*/listen.group = www/' /etc/php/7.3/fpm/pool.d/www.conf
sudo sed -i 's/;listen.mode.*/listen.mode = 0666/' /etc/php/7.3/fpm/pool.d/www.conf

sudo systemctl restart php7.3-fpm

安装 Composer

sudo apt install unzip

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
sudo mv composer.phar /usr/local/bin/composer

配置 Composer

仅中国大陆地区需要配置镜像。

IS_MAINLAND_CHINA=$(curl -s https://api.ip.sb/geoip | grep China)

if [ "$IS_MAINLAND_CHINA" ];then
  composer config -g repo.packagist composer https://packagist.laravel-china.org
fi

加速 Composer

composer global require hirak/prestissimo -vvv

填坑

上传文件提示：The file "" does not exist

修改 PHP FPM 配置 /etc/php/7.3/fpm/php.ini：

upload_max_filesize = 16M
post_max_size = 16M
