环境： ubuntu 17.04
1）先安装以下套件：
apt-get install gcc libxml2-dev
apt install linuxbrew-wrapper
2）下载和编译PHP源码
wget http://hk2.php.net/distributions/php-7.2.3.tar.gz
tar zxvf php-7.2.3.tar.gz
cd php-7.2.3/
./configure –enable-fpm –prefix=/usr/local/php –with-zlib –with-freetype –enable-magic-quotes –enable-fastcgi –with-mysql=/usr/local/server/mysql/ –enable-track-vars –enable-ftp –with-config-file-path=/usr/local/php/etc –with-zip –enable-force-cgi-redirect
make && make install
3）配置php-fpm
cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
cd /usr/local/php/etc/php-fpm.d
cp php-fpm.conf.default php-fpm.conf
4）运行php-fpm
/usr/local/sbin/php-fpm
如果报错：
ERROR: failed to open configuration file ‘/usr/local/etc/php-fpm.conf’: No such file or directory (2)
ERROR: failed to load configuration file ‘/usr/local/etc/php-fpm.conf’
ERROR: FPM initialization failed
修改/usr/local/sbin/php-fpm/www.conf
修改user和group为 www-da
再运行 php-fpm ，应该不会报错了！
5）查看php-fpm是否在运行
ps aux | grep ‘php-fpm’
