yum -y update yum -y install lrszs nettools
关闭selinux
vi /etc/selinux/config,把里边的一行改为
SELINUX=disabled
改了之后保存，然后重启就可以了。
getenforce
安装docker
yum install docker docker-devel systemctl start docker.service systemctl enable docker.service

如果要修改nginx的配置文件，直接在宿主机上的/application/nginx/conf/ext.d/目录下修改*.conf ；使用下面命令加载配置文件：
docker exec [容器id] /application/nginx/sbin/nginx -t docker exec [容器id] /application/nginx/sbin/nginx -s reload
