cp php.ini-production /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default \
/usr/local/php/etc/php-fpm.d/www.conf
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
/etc/init.d/php-fpm start
配置PHP环境变量：
cat > /etc/profile.d/PHP-BIN.sh <<EOF
export PHP_BIN=/usr/local/php/bin
export PATH=\${PATH}:\${PHP_BIN}
EOF
source /etc/profile.d/PHP-BIN.sh
清除环境变量：
unset USER PHP_VERSION CPUS
