安装Docker

  1. 下载docker-ce的repo
curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
  1. 安装依赖
yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm

ps:containerd版本过低,无法安装docker,所以此处是升级containerd的

  1. 安装docker-ce
yum install docker-ce
  1. 启动docker
systemctl start docker
#开机自动启动
# systemctl enable docker
  1. 设置国内源
vi  /etc/docker/daemon.json 
"registry-mirrors": [
    "https://1nj0zren.mirror.aliyuncs.com","https://docker.mirrors.ustc.edu.cn",
    "http://f1361db2.m.daocloud.io", "https://registry.docker-cn.com"]
  1. 重启
sudo systemctl daemon-reload
sudo systemctl restart docker

安装Portainer

介绍一款docker可视化界面portainer,可以方便的查看启动删除停止容器,也可以管理镜像

docker pull portainer/portainer
docker run -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -d portainer/portainer

安装Jenkins

docker pull jenkinsci/blueocean

docker run -d --name jenkins -p 9001:8080  -p 50000:50000 --env PATH=/usr/share/maven/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/lib/jvm/java-1.8-openjdk/jre/bin:/usr/lib/jvm/java-1.8-openjdk/bin  -v /var/run/docker.sock:/var/run/docker.sock -v /dockerworkspace/jenkins:/var/jenkins_home -v /opt/maven:/usr/share/maven -v /etc/localtime:/etc/localtime jenkinsci/blueocean

Ps:

  1. jenkins插件清华大学镜像地址
    https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

  2. 可能会出现java.net.UnknownHostException,困扰了我很久,百度搜出来的答案都不靠谱。看了一篇文章说有可能是防火墙没关。关闭防火墙,重启立马好了。。坑啊

    systemctl status firewalld.service 查看防火墙状态
    systemctl stop firewalld.service 执行停止运行防火墙命令
    systemctl disable firewalld.service 禁止防火墙自启动
    

    防火墙的开启和自启动命令:

    1、启动:

    systemctl start firewalld.service
    

    2、防火墙随系统开启启动 :

    systemctl enable firewalld.service
    
  3. 报错:

    touch: cannot touch ‘/var/jenkins_home/copy_reference_file.log’: Permission denied
    Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?
    

    需要修改下目录权限, 因为当映射本地数据卷时,/home/docker/jenkins目录的拥有者为root用户,而容器中jenkins user的uid为1000

    sudo chown -R 1000:1000 /dockerworkspace/jenkins
    
  4. 8080端口是jenkins的端口,5000端口是master和slave通信端口

  5. jenkin调用docker没有权限时

    chmod 666 /var/run/docker.sock
    
  6. clock of the subversion server appears to be out of sync. This can result in inconsistent check out behavior.
    svn url末尾添加@HEAD

安装Maven

  1. 下载

    wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
    
  2. 解压

    tar xf /tmp/apache-maven-*.tar.gz -C /opt
    
  3. 设置环境变量(此处采用的dockerhub的jenkins,所以可以省略)

    nano /etc/profile.d/maven.sh
    

    粘贴以下代码:

    export JAVA_HOME=/usr/lib/jvm/java-1.8-openjdk
    
    export MAVEN_HOME=/usr/opt/maven
    
    export PATH=${MAVEN_HOME}/bin:${PATH}
    

    为了更好地控制 Maven 版本和更新,我们将 创建一个符号链接 maven ,该链接指向 Maven 安装目录:

    ln -s /opt/apache-maven-3.6.3 /opt/maven
    

    通过运行以下 chmod 命令使脚本可执行

    chmod +x /etc/profile.d/maven.sh
    

    使用以下 source 命令加载环境变量:

    source /etc/profile.d/maven.sh
    
  4. 构建Maven多模块项目

    配置一个maven风格的项目 然后在配置

    root pom 指向的是最顶级的pom.xml

    mvn clean install -pl ETECSA-SERVER/ETECSA-SERVER-EUREKA -am -amd -Dmaven.test.skip=true
    

    这样就单独构建ETECSA-SERVER-EUREKA这个jar,相关依赖也会构建好,不用将依赖提前放入maven仓库

    根据资料已知:

    参数 全称 释义 说明
    -pl --projects Build specified reactor projects instead of all projects 选项后可跟随{groupId}:{artifactId}或者所选模块的相对路径(多个模块以逗号分隔)
    -am --also-make If project list is specified, also build projects required by the list 表示同时处理选定模块所依赖的模块
    - amd --also-make-dependents If project list is specified, also build projects that depend on projects on the list 表示同时处理依赖选定模块的模块
    -N --Non-recursive Build projects without recursive 表示不递归子模块
    -rf --resume-from Resume reactor from specified project 表示从指定模块开始继续处理

Ps:

permission denied异常

解决方法:

将jenkins用户加入docker组,重启Jenkins服务

sudo gpasswd -a jenkins docker
sudo systemctl jenkins restart

搭建私有镜像仓库Harbor

  1. 下载

    wget -P /workspace/harbor/     https://github.com/vmware/harbor/releases/download/v1.10.2/harbor-online-installer-v1.10.2.tgz
    
  2. 解压

    tar zxf harbor-online-installer-v1.10.2.tgz
    
  3. 修改配置文件,配置文件为:harbor.yml

  4. 进入harbor目录下,运行脚本

    ./install.sh
    
  5. 安装docker-compose

     #国内镜像   
     curl -L "https://get.daocloud.io/docker/compose/releases/download/v1.25.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    
  6. 给docker-compose执行权限,运行命令:

    chmod +x /usr/local/bin/docker-compose
    
  7. 测试上传和下载镜像,修改各docker client配置

    nano /etc/docker/daemon.json
    
    "insecure-registries":["10.1.20.16:9002"]
    

Ps:docker 官方私有仓库镜像register

docker pull registry
 docker run -d -v /opt/registry:/var/lib/registry -p 9001:5000 --restart=always --name registry registry:latest

Jenkins Pipe脚本示例(拉取svn代码build image push到镜像仓库)

def getHost(ip){
   def remote = [:]
    remote.name = 'server-${ip}'
    remote.host = ip
    remote.port = 22
    remote.allowAnyHosts = true
    withCredentials([usernamePassword(credentialsId: '31ed3f9c-3e80-496d-9733-98b78db29128', passwordVariable: 'password', usernameVariable: 'userName')]) {
        remote.user = "${userName}"
        remote.password = "${password}"

其他手动部署方式

  1. docker-compose部署服务

有三种方式:webEditor,上传docker-compose文件,git仓库获取docker-compose

  1. 命令行部署
  docker run -p 8761:8761 --name demo -d 10.1.20.16:9002/hn/demo:v1.0.0

虚拟机IP 变动解决方法

进入到/etc/sysconfig/network-scripts

目录下面ls后有个文档(我的是ifcfg-ens33) ifcfg-eno16777736(不同机器后面数字会不相同),编辑该文件内容,将BOOTPROTO=dhcp的值改为static

并在最后面加上:

DNS1=114.114.114.114 --dns地址

IPADDR=192.168.49.128 --需要设置的ip地址

NETMASK=255.255.255.0 --子网掩码

GATEWAY=192.168.49.1 --网关

nmcli c reload
