5、说明
1、创建自启动脚本以后都要给可执行权限，如：
chmod a+x /etc/init.d/nginx
chmod a+x /etc/init.d/php-fpm2、服务文件说明
[Unit]:服务的说明
Description:描述服务
After:描述服务类别
[Service]服务运行参数的设置
Type=forking是后台运行的形式
ExecStart为服务的具体运行命令
ExecReload为重启命令
ExecStop为停止命令
PrivateTmp=True表示给服务分配独立的临时空间
注意：[Service]的启动、重启、停止命令全部要求使用绝对路径
[Install]服务安装的相关设置，可设置为多用户3、服务文件目录：
/lib/systemd/system 4、命令说明：
启动nginx服务
systemctl start nginx.service
设置开机自启动
systemctl enable nginx.service
停止开机自启动
systemctl disable nginx.service
查看服务当前状态
systemctl status nginx.service
重新启动服务
systemctl restart nginx.service
查看所有已启动的服务
systemctl list-units --type=service参考：
