cat <<EOF > /etc/profile.d/php.sh
export PATH=/data/service/php/bin:\$PATH

# 生效环境变量
. /etc/profile
配置php-fpm
cp php.ini-production /data/service/php/etc/php.ini
cp /data/service/php/etc/php-fpm.conf.default /data/service/php/etc/php-fpm.conf
cp /data/service/php/etc/php-fpm.d/www.conf.default /data/service/php/etc/php-fpm.d/www.conf
配置php-fpm服务
# 注意：这个文件是根据上面C++编译配置动态生成的文件，里面写了上面配置的路径
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
# 启动权限
chmod +x /etc/init.d/php-fpm
启动：
# 增加开机启动
systemctl enable php-fpm
systemctl start php-fpm
