一。拓扑环境：
IP:192.168.93.202 docker registry服务器
IP:192.168.93.201 docker client服务器
关闭selinux及防火墙
修改/etc/hosts文件
192.168.93.202 docker.shengjing.com
hostnamectl set-hostname docker.shengjing.com (永久修改主机名）
安装依赖的软件包：
yum install gcc make pcre-devel pcre openssl-devel httpd-tools zlib-devel -y
生成根密钥：
先把
/etc/pki/CA/cacert.pem
/etc/pki/CA/index.txt
/etc/pki/CA/index.txt.attr
/etc/pki/CA/index.txt.old
/etc/pki/CA/serial
/etc/pki/CA/serial.old
删除掉!
cd /etc/pki/CA
(umask 077; openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096)
[root@docker CA]# (umask 077; openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096)
Generating RSA private key, 2048 bit long modulus
..................................................................................................................................+++
.......................................................+++
e is 65537 (0x10001)
生成根证书
openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 365
Generating RSA private key, 2048 bit long modulus
..................................................................................................................................+++
.......................................................+++
e is 65537 (0x10001)
[root@docker CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:beijing
Locality Name (eg, city) [Default City]:beijing
Organization Name (eg, company) [Default Company Ltd]:sjwl
Organizational Unit Name (eg, section) []:sjwl
Common Name (eg, your name or your server's hostname) []:docker.shengjing.com
Email Address []:mengxl@shengjing360.com
会提示输入一些内容，因为是私有的，所以可以随便输入，最好记住能与后面保持一致,特别是"Common Name”。必须要和hostname显示的一致。mengxl@shengjing360.com要记住！
上面的自签证书cacert.pem应该生成在/etc/pki/CA下
[root@docker CA]# ls
cacert.pem certs crl newcerts private
为nginx web服务器生成ssl密钥
mkdir /usr/local/nginx/ssl
cd /usr/local/nginx/ssl
[root@docker ssl]#(umask 077; openssl genrsa -out /usr/local/nginx/ssl/nginx.key 2048)
Generating RSA private key, 2048 bit long modulus
.....................................................+++
....................................................................................................................+++
e is 65537 (0x10001)
查看nginx服务器的密钥
[root@docker ssl]# ls
nginx.key
为nginx生成证书签署请求
执行 openssl req -new -key /usr/local/nginx/ssl/nginx.key -out /usr/local/nginx/ssl/nginx.csr

A challenge password []:

同样会提示输入一些内容，Commone Name一定要是你要授予证书的服务器域名或主机名，challenge password不填。
私有CA根据请求来签发证书
[root@docker ssl]# touch /etc/pki/CA/index.txt
[root@docker ssl]# touch /etc/pki/CA/serial
[root@docker ssl]# echo 00 > /etc/pki/CA/serial
执行
[root@docker ssl]# openssl ca -in /usr/local/nginx/ssl/nginx.csr -out /etc/pki/CA/certs/nginx.crt -days 365
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature
Signature ok

查看nginx的证书
[root@docker ssl]# cd /etc/pki/CA/certs/
[root@docker certs]# ls
nginx.crt
cp /etc/pki/CA/certs/nginx.crt /usr/local/nginx/ssl/
查看证书中的信息：
~]# openssl x509 -in /etc/pki/CA/certs/nginx.crt -noout -serial -subject

生成htpasswd
[root@localhost]# htpasswd -cb /usr/local/nginx/conf/.htpasswd admin admin
浏览器中：https://docker.shengjing.com
输入用户：admin
密码： admin
出现nginx测试页面
当把这条#proxy_pass http://registry;的注释#去掉
页面就报502，因为后端代理docker registry还没有启动
至此证明https认证完成

搭建docker registry V2
[root@localhost ~]# systemctl stop docker
[root@localhost ~]# vim /etc/sysconfig/docker
修改后：
OPTIONS='--selinux-enabled --insecure-registry dockertest.shengjing.com'
添加--insecure-registry docker.shengjing.com 红色的是私有仓库的域名，更前面生成密钥时候的域名对应
配置密钥文件
mkdir -p /etc/docker/certs.d/hc.docker.io
cp /etc/pki/CA/cacert.pem /etc/docker/certs.d//hc.docker.io/ca-certificates.crt

这里注意如果运行时报如下错误：

vi /etc/sysconfig/docker
OPTIONS='--selinux-enabled --insecure-registry docker.shengjing.com'
mkdir -pv /etc/docker/certs.d/docker.shengjing.com
cp /root/cacert.pem /etc/docker/certs.d/docker.shengjing.com/

vi /etc/hosts
192.168.93.202 docker.shengjing.com
重启下服务器
第一次我登陆时报错，如下：
[root@localhost ~]# docker login https://docker.shengjing.com
Username: admin
Password:
Email:
Error response from daemon: invalid registry endpoint https://docker.shengjing.com/v0/: unable to ping registry endpoint https://docker.shengjing.com/v0/
v2 ping attempt failed with error: Get https://docker.shengjing.com/v2/: x509: certificate signed by unknown authority
v1 ping attempt failed with error: Get https://docker.shengjing.com/v1/_ping: x509: certificate signed by unknown authority. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry docker.shengjing.com` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/docker.shengjing.com/ca.crt
怎么折腾都不行，看错误说是证书问题，最后放大招，另一台client测试，没问题，出问题的服务器恢复快照后也没问题，奇了葩了。
正常应该是这样：
[root@localhost ~]# docker login https://docker.shengjing.com
Username (admin): admin
Password:
WARNING: login credentials saved in /root/.docker/config.json
Login Succeeded
[root@localhost ~]# curl https://admin:admin@docker.shengjing.com/v2/
{}[root@localhost ~]#
到此，私有基于证书的ngix + registryv2 结束，累死老子了，最郁闷的快搭建完了才发现有个更牛逼的开源企业级私有registry，还是提供界面的中文的，哈哈，各位关注我接下来的博客吧
