第一次安装harbor的时候为了方便，安装成了http方式，但是后面时候的时候发现各种不方便，因为docker客户端登录镜像源的时候都是默认是https方式，所以每一个客户端都要特别的设置，很是麻烦。因此决定将http方式改为https方式。记录一下操作过程。
参考官网的安装文档进行操作，如下：
https://github.com/goharbor/harbor/blob/master/docs/configure_https.md
创建CA密钥对： openssl genrsa -out ca.key 4096 openssl req -x509 -new -nodes -sha512 -days 36500 \ -subj "/C=SC/ST=CHENGDU/L=CHENGDU/O=example/OU=Personal/CN=yuweibnig.com" \ -key ca.key \ -out ca.crt openssl genrsa -out yuweibing.com.key 4096 创建web服务器端秘钥对： openssl req -sha512 -new \ -subj "/C=SC/ST=CHENGDU/L=CHENGDU/O=example/OU=Personal/CN=yuweibnig.com" \ -key yuweibing.com.key \ -out yuweibing.com.csr 使web服务器到CA进行签约： cat > v3.ext <<-EOF authorityKeyIdentifier=keyid,issuer basicConstraints=CA:FALSE keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment extendedKeyUsage = serverAuth subjectAltName = @alt_names [alt_names] DNS.1=yuweibing.com DNS.2=yuweibing DNS.3=harbor EOF openssl x509 -req -sha512 -days 3650 \ -extfile v3.ext \ -CA ca.crt -CAkey ca.key -CAcreateserial \ -in yuweibing.com.csr \ -out yuweibing.com.crt 执行结果显示如下： [root@harbor ssl]# openssl x509 -req -sha512 -days 3650 \ > -extfile v3.ext \ > -CA ca.crt -CAkey ca.key -CAcreateserial \ > -in yuweibing.com.csr \ > -out yuweibing.com.crt Signature ok subject=/C=SC/ST=CHENGDU/L=CHENGDU/O=example/OU=Personal/CN=yuweibnig.com Getting CA Private Key [root@harbor ssl]#
修改harbor.cfg配置文件中以下参数 ：
hostname = yuweibing.com
ui_url_protocol = https
ssl_cert = /software/harbor/ssl/yuweibing.com.crt
ssl_cert_key = /software/harbor/ssl/yuweibing.com.key
secretkey_path = /software/harbor/ssl
然后执行prepare：
./prepare
然后执行install:
./install.sh
以下是执行结果：

For more details, please visit https://github.com/goharbor/harbor . [root@harbor harbor]# ./install.sh
接下来修改windows本机客户端的hosts文件强制解析域名： reg.yuweibing.com
192.168.1.44reg.yuweibing.com
192.168.170.44reg.yuweibing.com
然后就可以在windows客户端上输入域名 reg.yuweibing.com进行访问harbor的web网页了，如下：
登录进去后发现原来的用户信息和镜像数据都还在，还是不错。
接下来验证docker客户端是否能够正常从harbor拉取镜像：
[root@k8s1 ~]# docker login yuweibing.com Username: ywb Password: Error response from daemon: Get https://yuweibing.com/v2/: x509: certificate signed by unknown authority
发现认证失败。原因是还需要设置docker对于yuweibing.com这个域名的认证信息，将这个域名的公钥私钥和CA文件拷贝到docker的认证目录：/etc/docker/certs.d/yuweibing.com/ ，操作如下：
进入上面的秘钥文件所在的ssl目录，并执行如下命令： openssl x509 -inform PEM -in yuweibing.com.crt -out yuweibing.com.cert cp yuweibing.com.cert /etc/docker/certs.d/yuweibing.com/ cp yuweibing.com.key /etc/docker/certs.d/yuweibing.com/ cp ca.crt /etc/docker/certs.d/yuweibing.com/
将上面生成的3个文件同样scp拷贝到需要登录harbor的所有docker客户端的/etc/docker/certs.d/yuweibing.com/目录中，注意这个目录需要新建，同时需要在docker客户端中修改hosts文件解析yuweibing.com。
再次验证一下：
[root@k8s1 yuweibing.com]# docker login yuweibing.com Username: ywb Password: WARNING! Your password will be stored unencrypted in /root/.docker/config.json. Configure a credential helper to remove this warning. See https://docs.docker.com/engine/reference/commandline/login/#credentials-store Login Succeeded [root@k8s1 yuweibing.com]#
验证成功！
总结：
如果为了在安装harbor的时候省事采用http的方式部署，使用的时候docker客户端默认使用register仓库的时候都是使用安全连接https，如果要改为http需要修改docker配置，很是麻烦。因此还是需要使用https方式。
从http方式改为https方式主要是需要重新生成CA证书（颁发机构），web服务器证书（harbor服务器），以及服务器向CA进行签发注册。之后修改harbor.cfg配置文件，将服务器证书文件配置到配置文件中，修改hostname从IP地址改为域名，重新prepare和install ，install程序会自己将原来的docker-compose中的容器删除重新生成。
重新安装后的用户信息和镜像数据都会保留。
最后不要忘记配置docker客户端harbor服务器的公钥私钥，并且做好域名解析，如果没有dns服务器解析，就直接修改docker客户端上的hosts文件解析harbor配置的域名。
