## Harbor部署 ##

### 安装docker和compose ###

安装需要的安装包
    yum install -y yum-utils
    
    设置镜像仓库
    我们用阿里云
    
    yum-config-manager \
        --add-repo \
        http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
    
    开启存储库
    yum-config-manager --enable docker-ce-nightly
    yum-config-manager --enable docker-ce-test
    
    安装docker
    yum install docker-ce docker-ce-cli containerd.io
    
    systemctl enable docker --now
    
    下载安装compose
    curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose  
    
    授权
    chmod +x /usr/local/bin/docker-compose 
    
    查看版本
    docker-compose version

### 安装harbor ###

使用的 harbor-offline-installer-v1.9.1

[root@harbor ~]# tar -xf harbor-offline-installer-v1.9.1.tar 
    [root@harbor ~]# ls
    harbor  harbor-offline-installer-v1.9.1.tar
    [root@harbor ~]# cd harbor
    [root@harbor harbor]# ls
    harbor.v1.9.1.tar.gz  harbor.yml  install.sh  LICENSE  prepare
    
    修改harbor.yml 文件里面的hostname 改成本机地址
    [root@harbor harbor]# vim harbor.yml 
    hostname: 192.168.188.91
    
    配置http镜像仓库可信任
    vim /etc/docker/daemon.json
    添加
    
    {
        "insecure-registries": ["192.168.188.91"]}
    
    systemctl restart docker
    
    拉取镜像
    ./prepare
    
    安装
    ./install.sh

### 测试推送镜像 ###

换一台安装过docker的服务器
    
    配置http镜像仓库可信任
    vim /etc/docker/daemon.json
    添加
    
    {
        "insecure-registries": ["192.168.188.91"]}
    
    登录仓库
    docker login 192.168.188.91 -uadmin -pHarbor12345
    
    [root@gitlab ~]# docker login 192.168.188.91 -uadmin -pHarbor12345
    WARNING! Using --password via the CLI is insecure. Use --password-stdin.
    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
    
    现在下载一个镜像nginx
    docker pull nginx
    
    给镜像打tag
    docker tag nginx:latest 192.168.188.91/maomao/nginx
    
    上传镜像
    docker push 192.168.188.91/maomao/nginx
    
    再通过浏览器查看上传的镜像

# 安装git或者gitlab #

## 使用git ##

*  Git是一个开源的分布式版本控制系统，可以有效、高速地处理从很小到非常大的项目版本管理。
 *  Git 是 Linus Torvalds 为了帮助管理 Linux 内核开发而开发的一个开放源码的版本控制软件。

安装git首先需要拥有ssh软件，但是该程序linux是自带拥有的，所以可以直接进行下载
    
    yum install -y git
    
    查看版本
    git version
    
    创建用户，用户名字随意，但是尽量还是使用和git相关的名字
    [root@gitlab ~]# useradd gitme
    [root@gitlab ~]# passwd gitme
    Changing password for user gitme.
    New password: 
    BAD PASSWORD: The password is shorter than 8 characters
    Retype new password: 
    passwd: all authentication tokens updated successfully.
    
    切换到gitme用户
    su - gitme
    
    在家目录创建
    mkdir demo.git
    cd demo.git
    git --bare init

## 使用gitlab ##

GitLab 是一个用于仓库管理系统的开源项目，使用Git作为代码管理工具，并在此基础上搭 建起来的web服务。安装方法是参考GitLab在GitHub上的Wiki页面。

国外站点下载比较慢，可以在国内镜像去下载，比如清华镜像

[Centos7 gitlab 12.9.5社区版][Centos7 gitlab 12.9.5]

下载完成之后将包上传至git服务器
    
    下载依赖
    yum install -y policycoreutils-python openssh-server
    
    通过rpm安装
    rpm -ivh gitlab-ee-12.9.5-ee.0.el6.x86_64.rpm

安装成功

修改配置文件
    vim /etc/gitlab/gitlab.rb
    
    修改地址
    external_url 'http://192.168.188.95'
    
    修改时区
    gitlab_rails['time_zone'] = 'Asia/Shanghai'
    
    将注释取消
    gitlab_rails['manage_backup_path'] = true
    gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"
    
    gitlab_rails['backup_archive_permissions'] = 0644
    备份保持的时间
    gitlab_rails['backup_keep_time'] = 604800
    
    加载配置
    gitlab-ctl reconfigure
    
    重启
    gitlab-ctl restart
    
    安装查看系统负载工具，这个工具必 须安装阿里云epplo源
    yum -y install htop 
    
    浏览器登录gitlab仓库

创建账号  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhbnRldmVubA_size_16_color_FFFFFF_t_70 4]  
修改密码之后 登录  
账号是root  
密码是你修改的

创建授权一个账号给开发使用

添加成员  
![在这里插入图片描述][20210508101518379.png]  
添加2个成员，一个是jenkins用户，用来拉取代码的。一个是maomao，用来提交代码的。

将gitlab仓库来去到开发本地

yum install -y git
    
    git clone http://192.168.188.95/maomao/springbootdemo.git
    
    [root@gitlab ~]# git clone http://192.168.188.95/maomao/springbootdemo.git
    Cloning into 'springbootdemo'...
    Username for 'http://192.168.188.95': maomao  
    Password for 'http://maomao@192.168.188.95': 
    warning: You appear to have cloned an empty repository.
    
    当前目录就会有一个仓库目录springbootdemo 
    [root@gitlab ~]# ls
    gitlab-ce-12.9.5-ce.0.el7.x86_64.rpm  springbootdemo  SpringBootDemo-master  SpringBootDemo-master.zip
    
    然后将项目目录移动到仓库目录
    [root@gitlab ~]# mv SpringBootDemo-master springbootdemo/
    [root@gitlab ~]# cd springbootdemo/
    [root@gitlab springbootdemo]# ls
    SpringBootDemo-master
    
    git add .
    
    git commit -m 'v1'
    
    如果这里出现
    *** Please tell me who you are.
    
    则需要验证用户
    git config user.name "maomao"
    git config user.email "123@qq.com"
    
    我们重来一次
    [root@gitlab springbootdemo]# git add .
    [root@gitlab springbootdemo]# git commit -m 'v1'
    [master (root-commit) 608f5ef] v1

# 安装Jenkins #

Jenkins是一款开源自动化服务器，旨在自动化连续集成和交付软件所涉及的重复技术任务。 Jenkins是基于Java的，可以从yum安装，也可以通过下载和运行其Web应用程序ARchive（WAR）文件进行安装 - 构成一个完整的Web应用程序的集合，该文件旨在在服务器上运行。

## 安装jenkins所需环境 ##

安装maven
    yum install -y maven
    
    安装jdk
    yum install -y java
    
    安装tomcat,上传安装包
    tar xf apache-tomcat-8.3.5.tar -C /usr/local
    cd /usr/local
    mv apache-tomcat-8.5.16 tomcat
    
    安装docker
    安装需要的安装包
    yum install -y yum-utils
    
    设置镜像仓库
    我们用阿里云
    
    yum-config-manager \
        --add-repo \
        http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
    
    安装docker
    yum install -y docker-ce docker-ce-cli containerd.io
    
    systemctl enable docker --now
    
    docker version

## 安装jenkins ##

我使用jenkins.war包进行安装

删除tomcat所有的网页文件并将jenkins解压到ROOT下
    cd /usr/local/tomcat/webapps/ROOT
    rm -rf ./*
    
    将jenkins.war放入/usr/local/tomcat/webapps/ROOT
    [root@jenkins ROOT]# mv /root/jenkins.war ./
    [root@jenkins ROOT]# ls
    jenkins.war
    
    解压war包
    unzip jenkins.war
    
    开启tomcat
    /usr/local/tomcat/bin/startup.sh
    
    配置镜像加速
    curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
    
    docker version >= 1.12
    {
        "registry-mirrors": ["http://f1361db2.m.daocloud.io"]}
    Success.
    You need to restart docker to take effect: sudo systemctl restart docker
    
    设置信任192.168.188.91 harbor仓库
    vim /etc/docker/daemon.json
    
    添加
    {
        "registry-mirrors": ["http://f1361db2.m.daocloud.io"],
            "insecure-registries":["192.168.188.91"]
    }
    
    重启docker
    systemctl restart docker
    
    生成ssh密钥对传送给git仓库主机
    ssh-keygen
    ssh-copy-id gitme@192.168.188.92
    
    这里gitme就是之前gitlab服务器创建的账户

通过浏览器打开jenkins

## 配置jenkins流水线工作 ##

从公开的git仓库下载课件代码文件
    git clone https://github.com/407777853/java-demo
    
    cd java-demo
    
    .git为隐藏文件目录
    vim .git/config
    
    将这个参数修改为自己创建的git仓库地址和仓库路径
    url =  gitme@192.168.188.92:/home/gitme/demo.git
    
    将java-demo代码上传到自己的git仓库上
    cd ~/java-demo
    添加指定目录到暂存区
    git add . 	
    
    描述
    git commit -m “all”
    
    将代码推送至远程仓库的master节点
    git push origin master

浏览器中打开jenkins

1.  添加凭据
