ubuntu下编译安装 PHP 7.3的过程步骤

下载PHP源代码
首先需要从PHP官网下载PHP7.3.1的源代码，保存为php-7.3.1.tar.xz。http://cn2.php.net/distributions/php-7.3.1.tar.xz
在上述文件保存的目录中打开终端，使用命令将其解压，并使用cd进入解压后的目录
tar -xvJf ./php-7.3.1.tar.xz
cd php-7.3.11.安装依赖
其次，需要安装一些编译PHP所需要的依赖
sudo apt update
sudo apt install gcc
sudo apt install make
sudo apt install openssl
sudo apt install curl
sudo apt install libbz2-dev
sudo apt install libxml2-dev
sudo apt install libjpeg-dev
sudo apt install libpng-dev
sudo apt install libfreetype6-dev
sudo apt install libzip-dev2.预编译PHP
在编译前，需要对PHP进行配置，以供其生成对应的makefile文件
./configure –prefix=/usr/local/php –with-config-file-path=/usr/local/php/etc –enable-fpm –with-fpm-user=www –with-fpm-group=www –with-mysqli –with-pdo-mysql –with-iconv-dir –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir=/usr –enable-xml –disable-rpath –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –enable-mbregex –enable-mbstring –enable-ftp –with-gd –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-xmlrpc –enable-zip –enable-soap –without-pear –with-gettext –disable-fileinfo –enable-maintainer-zts
配置成功后会出现如下字样

Thank you for using PHP.3.编译并安装PHP
make
make install4.验证PHP
可以使用如下指令来输出PHP的版本，来验证是否正确安装
/usr/local/php/bin/php -v
如果正确安装，将会出现如下内容
PHP 7.3.1 (cli) (built: Jan 18 2019 20:11:04) ( ZTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.1, Copyright (c) 1998-2018 Zend Technologies
到这一步为止，PHP7.3.1便成功从源代码编译安装了。5.复制php.ini
编译安装后的目录并不会有现成的php.ini，需要手动复制过去。
在解压出来的源代码目录中，有供开发环境使用的php.ini-development和供生产环境使用的php.ini-production。cp php.ini-development /usr/local/php/etc/php.ini
cp /usr/local/php5/etc/php-fpm.conf.default /usr/local/php5/etc/php-fpm.conf
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
/usr/local/php5/sbin/php-fpm
启动php报错
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
#/usr/local/php/sbin/php-fpm
