export PATH=$PATH:/usr/local/php/bin
执行文件
source /etc/profile
查看php版本
php -v
配置php-fpm
安装完成后可以通过sapi/fpm/php-fpm.server来启动php-fpm了。不过为了以后管理方便，通常需要将配置文件统一放到/etc目录下，并将php-fpm.server添加至systemctl服务。如下
mkdir -p /etc/php-fpm.d cp php.ini-production /etc/php.ini cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/ cp /usr/local/php/etc/php-fpm.conf.derault /etc/php-fpm.conf cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf修改/usr/lib/systemd/system/php-fpm.service文件使其执行正确的路径，如下：
vi /usr/lib/systemd/system/php-fpm.service # 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
开机启动
systemctl enable php-fpm.service
启动php-fpm
systemctl start php-fpm.service
