linux 运维自动化之ansible，使用ansible的playbook实现自动化安装httpd

1、环境搭建

1.自动化管理机
192.168.170.7  自动化管理极ansible
被管理节点以下三台
192.168.170.6
192.168.170.17
192.168.170.37

1. yum install  ansible -y  #装包
2.rpm -ql  ansible | more   #查看主要文件
3.vim /etc/ansible/hosts    #配置主机清单
[wbs]
192.168.170.6
192.168.170.17
[apps]
192.168.170.37
[dbs]
192.168.170.6
4.ssh-keygen 实现基于sshkey验证管理
　　ssh-copy-id 192.168.170.6
　　ssh-copy-id 192.168.170.17
　　ssh-copy-id 192.168.170.37
5、 vim /etc/ansible/ansible.cfg #修改配置文件 一般保持默认
　　#host_key_checking= False # 检查对应服务器的host_key，建议取消注释
6、配置完毕我们用ping模块测试下链接情况
[root@chujiapeng ~]# ansible all -m ping
192.168.170.37 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
}, 
"changed": false, 
"ping": "pong"
}
192.168.170.6 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
}, 
"changed": false, 
"ping": "pong"
}
192.168.170.17 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
}, 
"changed": false, 
"ping": "pong"
}

2.使用ansible的playbook实现自动化安装httpd

1.#ansible 机器上准备httpd的配置文件
1、mkdir /data/playbook
2、cd /data/playbook
3、yum install httpd -y
4.cp /etc/httpd/conf/httpd.conf .

准备脚本

vim httpd.yml

---
- hosts: wbs
  remote_user: root

  tasks:
    - name: install
      yum: name=httpd
    - name: config
      copy: src=/data/playbook/httpd.conf dest=/etc/httpd/conf/
      notify: restart httpd
    - name: service
      service: name=httpd state=started enabled=yes
   
  handlers:
    - name: restart httpd
      service: name=httpd state=restarted

3.测试

 

 

 把配置文件的端口改成9527

 

 执行自动化部署脚本

 

 检查远程主机是否启动，我们看到 两台主机服务已经起来

 

 

 

 

 测试成功
