Jenkins安装

Docker常用命令

docker system df 查看磁盘占用
docker system df 清除磁盘
du -sh 目录占磁盘大小

Docker运行时增加Volume映射

# 通过commit来复制一个同样的容器, 然后基于该容器 增加映射命令
docker commit xxxxId  newContainerName
docker stop xxxxId
docker run -v /var/xx:/var/xx ... newContainerName

Jenkins批量增加用户

# 下载jar
curl -O http://192.168.159.131:7010/jnlpJars/jenkins-cli.jar

echo 'jenkins.model.Jenkins.instance.securityRealm.createAccount("user1", "password123")' | java -jar jenkins-cli.jar -auth admin:admin -s http://192.168.159.131:7010/ groovy =

通过chinese-to-pinyin生成用户名

# 安装chinese-to-pinyin
npm install chinese-to-pinyin --save

# 脚本
var pinyin = require("chinese-to-pinyin")
var a = '张三/n李四'
var arr = a.split("\n")
var s = "echo 'jenkins.model.Jenkins.instance.securityRealm.createAccount(\"username\", \"123456\")' | java -jar jenkins-cli.jar -auth admin:admin -s http://192.168.159.131:7010/ groovy ="
arr.forEach(e => {
    var name = pinyin(e, {removeTone: true,removeSpace: true})
    var x = s.replace("username",name)
    console.log(x)
});

加入Prometheus监控

#查看发行版: 
cat /etc/os-release
# Jenkins安装插件
Prometheus metrics plugin

# 增加prometheus配置
  - job_name: jenkins
    metrics_path: /prometheus
    scrape_interval: 10s
    scrape_timeout: 10s
    static_configs:
      - targets: ['192.168.159.131:7010']
# 使用Grafana Dashboard

Ansible实现自动部署

安装Ansible

apt-get install vim
# 增加镜像源
echo '
deb https://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb-src https://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb https://mirrors.aliyun.com/debian-security/ bullseye-security main
deb-src https://mirrors.aliyun.com/debian-security/ bullseye-security main
deb https://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb-src https://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb https://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib
deb-src https://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib' >  /etc/apt/sources.list

apt-get update

# 安装 ssh-keygen
apt-get install ssh -y
# 启动sshd
/etc/init.d/ssh start

#ssh设置
#在docker中jenkins下安装
# 生成密钥
ssh-keygen
# 将本地密钥传输到远程
ssh-copy-id -p 45685   root@localhost

apt-get install ansible -y
# 测试
ansible all -m ping
ansible-galaxy --version
# 安装role
ansible-galaxy install geerlingguy.jenkins
# 设置主机
vi /etc/ansible/hosts

Ansible playbook重启远端服务

- hosts: localhost
  vars:
    today_date: ""
  tasks:
    - name: copyfile
      copy:
        src: /opt/dccd-admin/dccd-admin-server.jar
        dest: /opt/dccd-admin/dccd-admin-server.jar
        remote_src: yes

          #- name: chdir
          # shell:
          # chdir: /opt/dccd-admin

    - name: restart dccd-admin
      command:
        cmd: ./remote_start_app.sh restart
      register: restart_dccd
      args:
        chdir: /opt/dccd-admin

    - name: debug_info
      debug:
        var: restart_dccd

Node环境安装

# 下载匹配版本
http://nodejs.cn/download/

tar -xvf   node-v16-linux-x64.tar.xz   
mv node-v16-linux-x64  node
# 建立软连接
ln -s /opt/node/bin/npm /usr/bin/npm
ln -s /opt/node/bin/node /usr/bin/node

# 检验
node -v

Gradle环境安装

# 安装路径
/opt/gradle/gradle-7.3.2

# 下载链接
wget https://services.gradle.org/distributions/gradle-7.3.2-all.zip
unzip gradle-7.3.2-all.zip

Sonar安装

docker run -d --name sonarqube -e SONAR_ES_BOOTSTRAP_CHECKS_DISABLE=true -p 9000:9000 sonarqube:latest

Docker迁移目录

因为Docker占空间较大, 原磁盘已经不够了, 从/var迁移到/opt下

# 停止docker服务
systemctl stop docker
systemctl stop docker.socket

# 备份 /var/lib/docker目录下面的文件到 /opt/var/lib/ 
rsync -avz /var/lib/docker /opt/var/lib/

# 配置 /etc/systemd/system/docker.service.d/devicemapper.conf。查看 devicemapper.conf 是否存在。如果不存在，就新建。
sudo mkdir -p /etc/systemd/system/docker.service.d/
sudo vi /etc/systemd/system/docker.service.d/devicemapper.conf

#  在 devicemapper.conf 写入：（同步的时候把父文件夹一并同步过来，实际上的目录应在 /opt/var/lib/docker ）
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --graph=/opt/var/lib/docker

# 重新加载 docker
systemctl daemon-reload
systemctl restart docker
systemctl enable docker

docker info

# 删除 /var/lib/docker/ 目录中的文件
