在虚拟机部署了一套harbor做实验
，发现虚机的地址变了导致harbor下载镜像失败了
。建议大家再做实验的时候可以将DHCP改成STATIC地址。
以下是我的做法
：
修改主机hosts文件
# changeecho "192.168.10.2 harbor.example.com " >>/etc/hosts因为只需要内网访问，没必要去申请一个ssl证书，所以我就用openssl颁发自签名证书，实现https访问。
# 创建证书目录mkdir -p /data/cert && cd /data/cert#创建CA根证书openssl req -newkey rsa:4096 -nodes -sha256 -keyout ca.key -x509 -days 365 -out ca.crt -subj "/C=CN/L=zhejiang/O=lisea/CN=harbor-registry"#生成证书签名，注意域名openssl req -newkey rsa:4096 -nodes -sha256 -keyout harbor.example.com.key -out server.csr -subj "/C=CN/L=zhejiang/O=lisea/CN=harbor.example.com"#生成主机证书openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out harbor.example.com.crt修改Harbor配置文件
#install Dir /opt/harbor/harbor.cfgui_url_protocol = httpshostname = harbor.example.comssl_cert = /data/cert/harbor.example.com.crtssl_cert_key = /data/cert/harbor.example.com.key重启Harbor服务
#切换到安装目录cd /opt/harbor#重新生成配置./prepare#停止harbordocker-compose down -v#启动harbordocker-compose up -d配置docker客户端
# 更改host文件echo "192.168.10.2 harbor.example.com " >>/etc/hosts# 修改docker.service/usr/lib/systemd/system/docker.serviceExecStart=/usr/bin/dockerd --insecure-registry harbor.example.com测试
