镜像仓库Harbor私服高可用策略分析及部署

```# 一．分析指定Harbor高可用策略

主流的策略有那么几种:
1.harbor做双主复制
2.harbor集群挂载分布式cephfs存储
3.在k8s集群上部署harbor

第二种和第三种都是多个节点，然后挂载的分布式存储，然后为了保证数据的统一性使用单独的mysql数据库，这样以来存在mysql数据和镜像仓库数据单点存放，故障恢复难度大，安装操作复杂的问题

双主复制不存在这些问题，数据多点存放，而且扩容更改高可用模式操作简单，可以更换成主主从等模式。

二．安装docker-compose

#cat -a /etc/sysctl.conf <<-EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
然后重新加载 sysctl.conf 即可

#sysctl -p

最好在ifcnf-eth0中配置dns参数，hosts千万不要配置域名和ip。

安装docker-compose
方法一
curl -L https://github.com/docker/compose/releases/download/1.18.0/docker-compose-`uname -s-uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
#查看版本
docker-compose version

方法二
CentOS:
yum install epel-release -y
yum install python-pip -y
Ubuntu:
apt-get install python-pip -y

pip --version
pip install --upgrade pip
pip install -U -i https://pypi.tuna.tsinghua.edu.cn/simple docker-compose
docker-compose version
这里采用方法2

二．安装Harbor

Harbor私有仓库的安装
2个节点安装步骤一致
• 下载Harbor安装文件
从 github harbor 官网 release 页面下载指定版本的安装包。
1、在线安装包（不一定好使，自己找源）
$ wget https://github.com/vmware/harbor/releases/download/v1.1.2/harbor-online-installer-v1.1.2.tgz
$ tar xvf harbor-online-installer-v1.1.2.tgz
2、离线安装包
$ wget https://github.com/vmware/harbor/releases/download/v1.1.2/harbor-offline-installer-v1.1.2.tgz
$ tar xvf harbor-offline-installer-v1.1.2.tgz

本次离线安装。
推荐使用第二种，因为第一种在线安装可能由于官网源的网络波动导致安装失败。
• 配置Harbor
解压缩之后，目录下回生成harbor.conf文件，该文件就是Harbor的配置文件。

启动 Harbor
修改完配置文件后，在的当前目录执行./install.sh，Harbor服务就会根据当期目录下的docker-compose.yml开始下载依赖的镜像，检测并按照顺序依次启动各
./install.sh

四．配置https域名证书等

X509存在一些问题在对v3_ca

#vim /etc/pki/tls/openssl.cnf
[ v3_ca ]

subjectAltName = IP:192.168.0.64 #添加

因为要配置https，需要生成自签名的证书

#cd /data/harbor-data/cert
#openssl req -nodes -subj "/C=CN/ST=BeiJing/L=ChaoYao/CN=basic-repository.xxxx.com" -newkey rsa:2048 -keyout basic-repository.key -out basic-repository.csr

#openssl x509 -req -days 3650 -in basic-repository.csr -signkey basic-repository.key -out basic-repository.crt

#openssl x509 -req -in basic-repository.csr -CA basic-repository.crt -CAkey basic-repository.key -CAcreateserial -out basic-repository.crt -days 10000

如下目录是nginx容器的cert目录：（不一定会自己生成）
#mkdir /data/harbor_install/harbor/common/config/nginx/cert/

#ls /etc/docker/certs.d/
basic-registry.xxxx.com basic-repository.xxxx.com redhat.com redhat.io registry.access.redhat.com registry.xxxx.com repository.xxxx.com
#scp –a basic-repository.crt docker-IP:/etc/docker/cert.d/ basic-repository.xxxx.com

在传完证书的docker服务器上执行：
#mkdir –pv /etc/docker/cert.d/basic-repository.xxxx.com
#service docker restart

#docker login -u admin -p Harbor123456 repository.xxxx.com
1、停止Harbor
#docker-compose down -v
Stopping nginx ... done
Stopping harbor-jobservice ... done
......
Removing harbor-log ... done
Removing network harbor_harbor

#docker-compose stop

2、启动Harbor
#docker-compose up -d
Creating network "harbor_harbor" with the default driver
Creating harbor-log ...
......
Creating nginx
Creating harbor-jobservice ... done

#docker-compose start

#docker-compose up –d

3.当需要修改配置文件刷新配置时需要执行： #./prepare

Test：
#docker login -u admin -p Harbor repository.xxxx.com
#ls /etc/docker/certs.d/
#docker pull basic-registry.xxxx.com/xxxx/dubbo:latest
#docker images
#docker tag basic-registry.xxxx.com/xxxx/dubbo:latest repository.xxxx.com/basic/dubbo:latest
#docker push repository.xxxx.com/basic/dubbo:latest
