Ansible常用操作

原理

ansible是一款业界出名的运维工具，可将linux相关操作封装成playbook，将主机信息通过inventory进行管理。

安装

ansible是基于python开发的，执行pip install ansible即可。

inventory样例

[host]
172.18.12.10

[host:vars]
ansible_ssh_user=user
ansible_ssh_pass=pass
ansible_ssh_private_key_file=id_rsa
ansible_become=yes
ansible_become_method=su
ansible_become_user=root
ansible_become_pass=pass

playbook样例

- hosts: host
  remote_user: root
  tasks:
    - name: clean
      shell: rm -rf /home/dra*
    - name: scp package
      copy:
        src: "{{item}}"
        dest: /home/dra.tar.gz
      with_fileglob: "/home/*.tar.gz"
    - name: untar package
      unarchive:
        src: /home/dra.tar.gz
        dest: /home/
        remote_src: yes
    - name: install
      shell: cd /home/dra-*/script/ && bash install.sh
    - name: restart dgw
      shell: ps -ef|grep dsware_dgw|grep -v grep|awk '{print $2}'|xargs kill -9

常用ansible命令

运行指定play-book：ansible-playbook -i /home/x00250203/env/fsb/hosts install_dra.yaml

执行指定命令：ansible -i hosts ebackup -m shell -a "route -n"

设置连续IP：172.18.0.[1:2]

设置不严格检查：在hosts文件中配置ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
