开始编译

make && make install

配置环境变量

vi /etc/profile

文件末尾追加

PATH=$PATH:/usr/local/php/bin
export PATH

使改动立即生效

source /etc/profile

配置php-fpm

cp php.ini-production /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

启动php-fpm

killall php-fpm

/etc/init.d/php-fpm start

将php-fpm.server添加至systemctl服务

vi /usr/lib/systemd/system/php-fpm.service
#文件内容

It's not recommended to modify this file in-place, because it

will be overwritten during upgrades. If you want to customize,

the best way is to use the "systemctl edit" command.

[Unit]
Description=The PHP FastCGI Process Manager
After=network.target

[Service]
Type=simple
PIDFile=/var/run/php-fpm.pid
ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

第一次通过systemctl启动PHP服务时需要先将php-fpm服务enable：

systemctl enable php-fpm.service
systemctl start php-fpm.service
