ansible安装与部署 ansible安装与部署

【ansible安装与部署】1.安装ansible
yum install ansible -y
2.管理被控端，管理机先生成秘钥，然后推送公钥
[root@demo ~]# ssh-keygen
[root@demo ~]# do ssh-copy-id -i ~/.ssh/id_rsa.pub root@10.0.0.i; done
3.配置被管理的主机清单
[root@demo ~]# vim /etc/ansible/hosts
[web]
10.0.0.100
10.0.0.200
4.使用ansible的ad-hoc测试
[root@demo ~]# ansible all -m ping
4.1 执行远程命令
[root@demo ~]# ansible all -m shell -a "df -h"
5.ansible playbook自动化安装nginx
注意前面的空格
[root@demo ~]# vim playbook_nginx.yml

hosts: 主机组的名字
remote_user: root
vars:
http_port: 80
tasks:
- name: Add Nginx Yum Repository
  yum_repository:
  name: nginx
  description: Nginx Repository
  baseurl: http://nginx.org/packages/centos/7/$basearch/
  gpgcheck: no
- name: Install Nginx Server
  yum:
  name=nginx state=present
- name: Configure Nginx Server
  template: src=https://www.it610.com/article/default.conf.template dest=/etc/nginx/conf.d/default.conf
  notify: Restart Nginx Server
- name: Start Nginx Server
  service: name=nginx state=started enabled=yes
handlers:
- name: Restart Nginx Server
  service: name=nginx state=restarted

6.在yml同一文件下
default.conf.template文件如下
[root@demo ~]#vim default.conf.template
server {
listen {{ http_port }};
server_name localhost;

location / { root/usr/share/nginx/html; indexindex.html index.htm; }

}
7.执行ansible-playbook
检查语法
[root@demo ~]# ansible-playbook --syntax playbook_nginx.yml
模拟执行
[root@demo ~]# ansible-playbook -C playbook_nginx.yml
执行
[root@demo ~]# ansible-playbook playbook_nginx.yml
