配置php
php.ini-development 适合开发测试，如本地测试环境， php.ini-production拥有较高的安全性设定，适合服务器上线运营当产品。一般修改php.ini-production为php.ini
cp php.ini-production /usr/local/php/etc/php.ini 创建php-fpm.conf文件
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf创建www.conf文件
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf设置开机自动启动
vim /lib/systemd/system/php-fpm.service[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target[Service]
Type=simple
PIDFile=/run/php-fpm.pid
ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 MAINPIDExecStop=/bin/kill−SIGINTMAINPID[Install]
WantedBy=multi-user.target加入开机自动启动：
systemctl enable php-fpm.service关闭开机自动启动：
systemctl disable php-fpm.service常见错误
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.解决：
yum install -y yum-utils device-mapper-persistent-data lvm2
