ansible 初级使用 yum install ansible -y 设置本机免密钥登录到 192.168.1.21 ssh-copy-id 192.168.1.21 vim /etc/ansible/hosts 添加2行 [web] 192.168.1.21 命令行操作方法,:ansible 主机组或ip -m 指定模块 -a 模块对应的参数 ansible 192.168.1.21 -m shell -a "echo hello" 192.168.1.21 | SUCCESS | rc=0 >> hello ansible 192.168.1.21 -m setup # 主机所有信息 ansible 192.168.1.21 -m setup -a "filter=ansible_hostname" # 用setup模块取得主机名 192.168.1.21 | SUCCESS => { "ansible_facts": { "ansible_hostname": "21hostname" }, "changed": false } ansible web -m shell -a "echo hello" 192.168.1.21 | SUCCESS | rc=0 >> hello 编写简单的play-book cat test.yml --- - hosts: 192.168.1.21 tasks: - name: just test ansible shell: echo hello - name: get hostname setup: filter=ansible_hostname 执行 ansible-play test.yml PLAY [192.168.1.21] ******************************************************************************************************************************************************** TASK [Gathering Facts] ***************************************************************************************************************************************************** ok: [192.168.1.21] TASK [just test ansible] *************************************************************************************************************************************************** changed: [192.168.1.21] TASK [get hostname] ******************************************************************************************************************************************************** ok: [192.168.1.21] PLAY RECAP ***************************************************************************************************************************************************************** 192.168.1.21 : ok=3 changed=1 unreachable=0 failed=0 如需要指定其他ip,可以 --- - hosts: all # 这改成all tasks: - name: just test ansible shell: echo hello - name: get hostname setup: filter=ansible_hostname ansible-playbook -i '192.168.1.21,' test.yml # -i 指定执行清单 记得192.168.1.21, 后面有逗号. play-book 中传入默认变量 --- - hosts: 192.168.1.146 remote_user: root vars: - hello: hello-world # 设定hello 变量的默认值为 hello-world gather_facts: false # 可选参数 tasks: - name: var test shell: echo {{ hello }} > /dev/pts/0 ansible-play a.yml 输出为hello-world ansible-play a.yml -e hello=xiaoming 输出为小明 ansible play-book 一个套路,记得最基本的方法,使用其他模块一样的。 play-book 中做条件判断 - name: check kafka shell: pip list | grep kafka | wc -l ignore_errors: True register: check_kafka - name: pip install kafka-1.3.5 shell: pip install {{ item }} with_items: - kafka when: check_kafka.stdout == "0" 判断是否已经安装了kafka 没安装则安装,已安装则跳过。 - name: install zabbix-agent for centos-7 yum: name=zabbix22-agent.x86_64 state=present when: ansible_os_family == "RedHat" and ansible_distribution_major_version == "7" 判断是否是redhat或centos 7 版本,来安装对应的包。标签:参数 ror web change false check zab 密钥登录 hosts
