项目:git+gitlab+jenkins+ansible上线网站

作者:互联网

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

[root@docker2 nginxinstall]#
