Playbook部署httpd

1、环境准备

1.1、主机准备

http1 192.168.10.17
http2 192.168.10.18

1.2、设置免密码登陆

ssh-keygen -t rsa -C root@qq.com -f ~/.ssh/id_rsa -P ""
yum install sshpass -y
sshpass -proot ssh-copy-id -i ~/.ssh/id_rsa.pub -o StrictHostKeyChecking=no root@192.168.10.17
sshpass -proot ssh-copy-id -i ~/.ssh/id_rsa.pub -o StrictHostKeyChecking=no root@192.168.10.18

1.3、配置主机清单

]# vi /etc/ansible/hosts
[httpd]
192.168.10.17
192.168.10.18

1.4、编写playbood流程

1、定义play
2、定义task、（Installed、Configure、Init、Systemd）

2、编写安装配置 httpd 服务的 playbook 文件

cat << 'CAT_END' > install_httpd.yaml
- hosts: httpd
  tasks:
    - name: Install httpd Server
      yum:
        name: httpd
        state: present
    - name: Configure httpd Server
      copy:
        src: ./httpd.conf.j2
        dest: /etc/httpd/conf/httpd.conf
        owner: root
        group: root
        mode: 644
        backup: yes
      notify: restart httpd server
    - name: Init httpd Server
      copy:
        src: ./index.html.j2
        dest: /var/www/html/test.html

    - name: Systemd httpd Server
      systemd:
        name: httpd
        state: started
        enabled: yes
  handlers:
    - name: restart httpd server
      systemd:
        name: httpd
        state: restarted
CAT_END

3、检查 playbook 语法

ansible-playbook install_httpd.yaml --syntax-check

4、准备所需要的配置文件

4.1、index.html.j2

echo "This is web test page。" >index.html.j2

4.2、httpd.conf.j2

# 自行到测试机器，拷贝配置文件
scp root@192.168.10.16:/etc/httpd/conf/httpd.conf httpd.conf.j2

# 修改配置文件
sed -i '/^Listen/c Listen 0.0.0.0:80' httpd.conf.j2

5、开始部署

]# ansible-playbook install_httpd.yaml

6、访问服务器对应的 web 页面测试

~]# curl 192.168.10.17
This is web test page。


]# curl 192.168.10.18
This is web test page。
