Project requirements
1. Create a project in gitlab nginxinstall
2. write playbook, to achieve a key nginx deployment, the deployment of a static test page, the test results of the deployment
requirements:
deploy nginx
Port: 83
Run As: root
set the number of concurrent connections: 2048
root: / vaw / www / html
Other requirements:
the deployment of more than two nodes
with a role
with templates
3. Save the playbook written to gitlab warehouse
4.jenkins achieve sustained deployment
192.168.59.200 docker1 jenkins git ansible
192.168.59.201 docker2 gitlab git
192.168.59.12 test2
Step 1: Create a project in docker2 nginxinstall
Step two: docker1 cloning project
[root@docker1 ~]# mkdir /nginx [root@docker1 ~]# cd /nginx [root@docker1 nginx]# ls [root@docker1 nginx]# git clone http://[email protected]/root/nginxinstall.git Positive clones to 'nginxinstall' ... warning: You seem to clone an empty repository. [root@docker1 nginx]# cd nginxinstall/
Step Three: Write 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 "[email protected]" [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://[email protected]': 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://[email protected]/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://[email protected]': 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://[email protected]/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]#
