3.1 安装docker # 

yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce -y
systemctl start docker
systemctl enable docker

配置阿里云镜像源

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://fwvjnv59.mirror.aliyuncs.com"]
}
EOF
# 重载所有修改过的配置文件
sudo systemctl daemon-reload
sudo systemctl restart docker

sudo wget -O /etc/yum.repos.d/jenkins.repo https://img.zhufengpeixun.com/jenkins.repo
sudo rpm --import https://img.zhufengpeixun.com/jenkins.io.key
yum install jenkins -y

3.2.3 启动 Jenkins # 

 systemctl start jenkins.service

3.3.4 开放端口 # 

firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-port=50000/tcp --permanent
systemctl reload firewalld

3.3.5 打开浏览器访问 # 

http://8.136.218.128:8080/

3.3.6 查看密码 # 

cat /var/lib/jenkins/secrets/initialAdminPassword

3.3.7 修改插件镜像 # 

sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' /var/lib/jenkins/updates/default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' /var/lib/jenkins/updates/default.json

3.3.8 添加到docker用户组里 # 

sudo gpasswd -a jenkins docker  #将当前用户添加至docker用户组
newgrp docker                 #更新docker用户组

3.4 集成 Git 仓库 #

3.4.1 生成公钥私钥 # 

ssh-keygen -t rsa -C "zhufengnodejs@126.com"

3.4.2 Gitee 配置公钥 # 

cat ~/.ssh/id_rsa.pub

3.4.3 在Jenkins 配置私钥 #

3.5 构建镜像 #

3.5.1 编写 Dockerfile #

Dockerfile

FROM nginx:1.15

tar -zxvf ./nexus-3.29.0-02-unix.tar.gz
cd nexus-3.29.0-02/bin
./nexus start

firewall-cmd --zone=public --add-port=8081/tcp --permanent
firewall-cmd --zone=public --add-port=8082/tcp --permanent

http://8.136.218.128:8081/

nexus 还支持停止，重启等命令。可以在 bin 目录下执行 ./nexus help 查看更多命令

3.6.2 配置 Nexus # 

cat /root/sonatype-work/nexus3/admin.password

3.6.3 创建Docker私服 #

3.6.4 添加访问权限 #

3.6.5 登录制品库 #
