  • 项目:git+gitlab+jenkins+ansible上线网站

    项目需求

    1. 在gitlab中创建一个项目 nginxinstall
    2. 编写playbook,实现一键部署nginx、部署一个静态测试页、测试部署结果
    要求:
      部署nginx
      端口:83
      运行身份:root
      设置并发连接数:2048
      根目录:/vaw/www/html

    其他要求:
      部署两个以上节点
      用role
      用templates

    3. 将写好的playbook保存到gitlab仓库中
    4.jenkins实现持续部署

    192.168.59.200 docker1 jenkins git ansible
    192.168.59.201 docker2 gitlab git
    192.168.59.12 test2


    第一步:在docker2创建一个nginxinstall项目

     

    第二步:docker1克隆项目

    [root@docker1 ~]# mkdir /nginx
    [root@docker1 ~]# cd /nginx
    [root@docker1 nginx]# ls
    [root@docker1 nginx]# git clone http://root@192.168.59.201/root/nginxinstall.git
    正克隆到 'nginxinstall'...
    warning: 您似乎克隆了一个空版本库。
    [root@docker1 nginx]# cd nginxinstall/
    

      

    第三步:编写roles(docker1)

    [root@docker1 nginxinstall]# mkdir roles/nginx/{tasks,vars,templates,files} -p 
    [root@docker1 nginxinstall]# tree
    .
    └── roles
      └── nginx
        ├── files
        ├── tasks
        ├── templates
        └── vars
    
    6 directories, 0 files
    
    [root@docker1 nginxinstall]# vim ./roles/nginx/vars/main.yaml
    usr: root
    por: 83
    prc: 2048
    wok: /var/www/html
    [root@docker1 nginxinstall]# echo v1 > ./roles/nginx/files/index.html
    [root@docker1 nginxinstall]# cp /etc/nginx/nginx.conf ./roles/nginx/templates/nginx.conf.j2
    [root@docker1 nginxinstall]# vim ./roles/nginx/templates/nginx.conf.j2 
    ...
    user {{ usr }};
    
    events {
      worker_connections {{ prc }};
    }
    
    http {
      server {
        listen {{ por }};
      root {{ wok }};
    ...
    
    [root@docker1 nginxinstall]# vim ./roles/nginx/tasks/main.yaml
    - yum: name=nginx state=present
    - template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
    - service: name=nginx state=restarted
    - copy: src=index.html dest={{ wok }}
    
    [root@docker1 nginxinstall]# mkdir inventory
    [root@docker1 nginxinstall]# ls
    inventory roles
    [root@docker1 nginxinstall]# vim inventory/host
    [test]
    192.168.59.12
    
    [root@docker1 nginxinstall]# vim site.yaml
    - hosts: all
      roles:
      - name: nginx
    
    [root@docker1 nginxinstall]# vim /etc/sysconfig/jenkins
    ...
    JENKINS_USER="root"
    … 

    第四步:查看jenkins相关信息:

    [root@docker1 nginxinstall]# ps aux |grep jenkins
    root 13116 37.1 4.3 3694624 267464 ? Ssl 20:59 0:14 /etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=8080 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20
    root 13251 0.0 0.0 112724 988 pts/0 R+ 20:59 0:00 grep --color=auto jenkins
    [root@docker1 nginxinstall]# systemctl restart jenkins

    第五步:查看roles文件,并且模拟运行

    [root@docker1 nginxinstall]# tree
    .
    ├── inventory
    │   └── host
    ├── roles
    │   └── nginx
    │     ├── files
    │     │   └── index.html
    │     ├── tasks
    │     │   └── main.yaml
    │     ├── templates
    │     │   └── nginx.conf.j2
    │     └── vars
    │        └── main.yaml
    └── site.yaml
    7 directories, 6 files
    
    [root@docker1 nginxinstall]# ansible-playbook -C -i inventory/host site.yaml 
    PLAY [test] ************************************************************************************************************
    TASK [Gathering Facts] *************************************************************************************************
    ok: [192.168.59.12]
    TASK [nginx : yum] *****************************************************************************************************
    changed: [192.168.59.12]
    TASK [nginx : template] ************************************************************************************************
    changed: [192.168.59.12]
    TASK [nginx : service] *************************************************************************************************
    changed: [192.168.59.12]
    TASK [nginx : copy] ****************************************************************************************************
    changed: [192.168.59.12]
    PLAY RECAP *************************************************************************************************************
    192.168.59.12 : ok=5 changed=4 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

    第六步:上传v1版本:

    [root@docker1 nginxinstall]# git add .
    [root@docker1 nginxinstall]# git config --global user.email "you@example.com"
    [root@docker1 nginxinstall]# git config --global user.name "Your Name"
    [root@docker1 nginxinstall]# git commit -m v1
    [master(根提交) 030ce20] v1
    6 files changed, 104 insertions(+)
    create mode 100644 inventory/host
    create mode 100644 roles/nginx/files/index.html
    create mode 100644 roles/nginx/tasks/main.yaml
    create mode 100644 roles/nginx/templates/nginx.conf.j2
    create mode 100644 roles/nginx/vars/main.yaml
    create mode 100644 site.yaml
    [root@docker1 nginxinstall]# git push -u origin master
    Password for 'http://root@192.168.59.201': 
    Counting objects: 15, done.
    Compressing objects: 100% (5/5), done.
    Writing objects: 100% (15/15), 1.80 KiB | 0 bytes/s, done.
    Total 15 (delta 0), reused 0 (delta 0)
    To http://root@192.168.59.201/root/nginxinstall.git
    * [new branch] master -> master
    分支 master 设置为跟踪来自 origin 的远程分支 master

    第七步:docker1,网页布置jenkins
    1、创建hitlab用户凭证

     

    2、创建项目(nginx_install)

     

     

    3、复制项目链接

     

    4、填写项目

     

    5、填写shell

     

     


    6、构建

    第九步:验证在其他电脑能否上传:(docker2)

    [root@docker2 ~]# cd nginxinstall/
    [root@docker2 nginxinstall]# ls
    inventory roles site.yaml
    [root@docker2 nginxinstall]# vim roles/nginx/files/index.html 
    [root@docker2 nginxinstall]# git add .
    [root@docker2 nginxinstall]# ls
    inventory roles site.yaml
    [root@docker2 nginxinstall]# git commit -m v2
    [master 6a6dfa1] v2
    1 file changed, 1 insertion(+), 1 deletion(-)
    [root@docker2 nginxinstall]# git push -u origin master
    
    (gnome-ssh-askpass:14400): Gtk-WARNING **: 20:22:42.388: cannot open display: 
    error: unable to read askpass response from '/usr/libexec/openssh/gnome-ssh-askpass'
    Password for 'http://root@192.168.59.201': 
    Counting objects: 11, done.
    Compressing objects: 100% (3/3), done.
    Writing objects: 100% (6/6), 520 bytes | 0 bytes/s, done.
    Total 6 (delta 0), reused 0 (delta 0)
    To http://root@192.168.59.201/root/nginxinstall.git
    030ce20..6a6dfa1 master -> master
    分支 master 设置为跟踪来自 origin 的远程分支 master。
    [root@docker2 nginxinstall]#
