docker配置
限制容器资源
#CPU使用0-3总共4个核心，内存1G,--net=none不配置网络（桥接模式是pipework设置网络）dockerrun-itd--net=none--name=centos07--cpuset-cpus="0-3"-m1024M--memory-reservation1024Mcentos6-132.97.8.7-170106_2/bin/bash

1、将脚本移动到/etc/rc.d/init.d目录下mv/home/xy/docker_start.sh/etc/rc.d/init.d2、增加脚本的可执行权限chmod+x/etc/rc.d/init.d/docker_start.sh3、添加脚本到开机自动启动项目中cd/etc/rc.d/init.dchkconfig--add docker_start.shchkconfig docker_start.sh on
