• 【云原生】DevOps 环境搭建

    本文使用 Gitlab，Jenkins，Docker，K8s，Harbor 实现CICD环境搭建

    一、Gitlab环境部署
    说明：内存尽量给多点（2G以上），后面会安装一些软件，会占用内存
    1.1、安装依赖软件

    yum install curl openssh-server postfix

    • 1

    1.2、下载gitlab包并安装
    1.2.1、安装方法1:

    curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
yum install gitlab-ce

    • 1
    • 2

    1.2.2、安装方法2:

    下载地址：https://packages.gitlab.com/gitlab/gitlab-ce?filter=rpms&page=34
下载gitlab-ce-8.9.6-ce.0.el7.x86_64.rpm安装包到本地
上传gitlab-ce-8.9.6-ce.0.el7.x86_64.rpm软件包的到服务器，然后执行以下操作
安装软件包
[root@CentOS7 ~]# yum localinstall gitlab-ce-8.9.6-ce.0.el7.x86_64.rpm

    1.3、配置并启动

    gitlab-ctl reconfigure        #初始化

gitlab-ctl status             #查看状态

gitlab-ctl stop               #停止gitlab

gitlab-ctl start              #启动gitlab

    1.4、初始化后检查

    [root@CentOS7 ~]# gitlab-ctl status           #出现以下信息说明正确
run: gitlab-workhorse: (pid 2213) 68s; run: log: (pid 2058) 110s
run: logrotate: (pid 2077) 102s; run: log: (pid 2076) 102s
run: nginx: (pid 2064) 108s; run: log: (pid 2063) 108s
run: postgresql: (pid 1933) 130s; run: log: (pid 1932) 130s
run: redis: (pid 1850) 136s; run: log: (pid 1849) 136s
run: sidekiq: (pid 2048) 112s; run: log: (pid 2047) 112s
run: unicorn: (pid 2239) 55s; run: log: (pid 2015) 114s

    1.5、网页登陆配置gitlab
    在浏览器输入当前服务器的ip地址即可打开网页
    1.5.1、设置初始登陆的密码：
    在这里插入图片描述
    1.5.2、登陆gitlab（默认用户：root 密码：自定义）
    在这里插入图片描述
    1.5.3、登陆后的界面如下：
    在这里插入图片描述
    二、Jenkins环境部署
    2.1、下载存储库

      sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo
  sudo rpm --import https://pkg.jenkins.io/redhat/jenkins.io-2023.key

    2.2、安装jdk及jenkins

      yum install fontconfig tzdata-java java-17-openjdk
  yum install jenkins

    • 2

    2.3、启动jenkins

    systemctl status jenkins

    • 1

    2.4、启动完成后安装必要插件

    Git、Git Parameter、GitLab、Localization Support、Localization: Chinese (Simplified)、Pipeline、Publish Over SSH、SonarQube Scanner、

    3、安装Docker

    [root@localhost ~]# cat install-docker.sh 
#! /bin/bash
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce-18.06.2.ce-3.el7
设置docker的加速镜像
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io

    4、安装k8s集群见如下文档
    k8s安装文档
    5、安装Harnor仓库见如下文档
    Harbor仓库安装
    6、配置Jenkins Pipeline

    pipeline {
    agent any
	environment {
        image_name = "192.168.122.150/per-test/auth-service:${date}"
        server_name = "per-auth-service"
        namespace = "per"
     }
    stages {
        stage('pull code') {
            steps {
              checkout([$class: 'GitSCM', 
              branches: [[name: "${params.TAG}"]], 
              extensions: [],

              url: 'https://codeup.aliyun.com/63ee8eeba823fsf32dffwe/user-auth.git']]])
                updateGitlabCommitStatus(name: env.STAGE_NAME, state: 'success')
                   script{
                       env.BUILD_TASKS = env.STAGE_NAME + "√..." + env.TAB_STR
                   }
            }
        }
        stage('Code Build'){ 
	        steps {
                retry(2) { sh "/opt/maven/bin/mvn  clean package -U -Dmaven.test.skip=true" }
