密钥授权认证实现免密登陆

[root@ansible-centos7-shanghai-area6 ~]# ssh-keygen -t rsa
[root@ansible-centos7-shanghai-area6 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 10.0.2.21

在ansible/hosts中添加主机信息

[root@ansible-centos7-shanghai-area6 ~]# vim /etc/ansible/hosts 
#10.0.2.21 ansible_port=22 ansible_user=hj ansible_ssh_pass=v2L8x;pV
#test21 ansible_host=10.0.2.21 ansible_port=22 ansible_user=hj ansible_ssh_pass=v2L8x;pV
#test21 ansible_host=10.0.2.21 ansible_port=22 ansible_user=root
10.0.2.21 ansible_port=22 ansible_user=root

定义agent模板

[root@ansible-centos7-shanghai-area6 ~]#  vim /etc/ansible/zabbix_agentd.conf # 创建一个模板文件，里面包含agent中可变的变量，如：主机名和server地址
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server={{server}}
ServerActive={{server}}
Hostname={{hostname}}
Include=/etc/zabbix/zabbix_agentd.d/*.conf
UnsafeUserParameters=1

编写playbook文件

[root@ansible-centos7-shanghai-area6 ~]# vim /etc/ansible/linux-agent.yml
- hosts: zabbix-agent
  remote_user: root
  vars:
    server: 10.0.2.2
    hostname: "{{ ansible_hostname }}"
  tasks:
  - name: install rpm
    command: rpm -ivh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-agent-4.2.1-1.el7.x86_64.rpm

  - name: install agent
    command: yum install zabbix-agent -y
  - name: cp templates zabbix_agentd.conf to zabbix agentd
    template: src=/etc/ansible/zabbix_agentd.conf dest=/etc/zabbix/zabbix_agentd.conf

  - name: restart zabbix-agent
    command: systemctl restart zabbix-agent

执行playbook文件进行批量部署

[root@ansible-centos7-shanghai-area6 ~]#  ansible-playbook -i /etc/ansible/hosts /etc/ansible/linux-agent.yml

client 端验证服务运行情况

[hj@java10-centos7-shanghai-area6 ~]#  sudo  egrep -v "^$|^#" /etc/zabbix/zabbix_agentd.conf  # agent配置文件中的变量也修改完成
