Ansible-playbook小记
就是将很多的ad-hoc，以yaml格式的形式集合到了一起
hello world
---
- hosts: test
remote_user: root
vars:
com: /root
tasks:
- name: hello world
shell: ls {{ com }}vars自定义变量，引用的时候需要使用"{{}}"，注意都使用双引号吧，避免报错tasks是用来指定需要执行的任务
系统变量
{{ ansible_devices.sda.model }}条件语句
when语句
tasks:
- name: "shutdown Debian flavored systems"
command: /sbin/shutdown -t now
when: ansible_os_family == "Debian"bool值
vars:
epic: true
tasks:
- shell: echo "This certainly is epic"
when: peic
- shell: echo "This certainly is epic"
when: not peicwith_items循环语句
- name: add_several users
user: name={{ item }} state=present groups=wheel
with_items:
- testuser1
- testuser2with_nested嵌套循环
- name: users access control
mysql_user: name={{ item[0] }}
priv={{ item[2] }}.*.:ALL
append_privs=yes
password=foo
with_nested:
- ['alice','bob']
- ['clientdb','employeedb','providerdb']- 有条件的循环
tasts:
- command: echo {{ item }}
with_items: [0,2,4,6,8,10]
when: item > 5实战
编写一个安装Python flask环境的yml
---
- hosts: test
remote_user: root
become: true
tasks:
- name: install python for ubuntu
apt:
name: "{{ item }}"
state: latest
update_cache: yes
with_items:
- python-dev
- python-setuptools
when: ansible_distribution == 'Ubuntu'
- name: install python for centos
yum:
name: "{{ item }}"
state: installed
with_items:
- python-devel
- python-setuptools
when: ansible_distribution == 'CentOS'
- name: install pip
shell: easy_install pip
- name: pip install flask and redis
pip:
name: "{{ item }}"
with_items:
- flask
- redis
ansible_distribution系统变量用来检测机器是哪种操作系统
playbook编写zabbix
zabbix有server端，以及agent端- 两台机器，一台
centos，一台ubuntu hosts文件编写
centos ansible_ssh_port=22 ansible_ssh_host=xx.xx.xx.1 ansible_ssh_user=root
ubuntu ansible_ssh_port=22 ansible_ssh_host=xx.xx.xx.2 ansible_ssh_user=simon
[test]
centos
ubuntuyml文件编写
---
- hosts: test
remote_user: root
become: true
tasks:
- name: install zabbix rpm source
yum:
name: https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
state: installed
when: ansible_distribution == 'CentOS'
- name: download zabbix deb for ubuntu
get_url:
url: https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-2+xenial_all.deb
dest: /tmp/zabbix.deb
when: ansible_distribution == 'Ubuntu'
- name: install zabbix deb for ubuntu
apt:
# name: /tmp/zabbix.deb
deb: /tmp/zabbix.deb
# state: installed
- name: install zabbix server -> centos
yum:
name: "{{ item }}"
state: installed
with_items:
- zabbix-server-mysql
- zabbix-proxy-mysql
- zabbix-web-mysql
when: ansible_distribution == 'CentOS'
- name: install zabbix agent -> ubuntu
apt:
name: zabbix-agent
update_cache: yes
# state: installed
when: ansible_distribution == 'Ubuntu'
- name: config zabbix server
replace:
path: /etc/zabbix/zabbix_server.conf
regexp: DBUser=zabbix
replace: DBUser=root
when: ansible_distribution == 'CentOS'
- name: import db format for server
shell: zcat /usr/share/doc/zabbix-server-mysql-4.0/create.sql.gz | mysql -uroot -p zabbix
when: ansible_distribution == 'CentOS'
- name: disable selinux
selinux:
state: disabled
when: ansible_distribution == 'CentOS'
- name: start zabbix server
systemd:
name: zabbix-server
state: started
when: ansible_distribution == 'CentOS'
- name: start zabbix agent
systemd:
name: zabbix-agent
state: started
when: ansible_distribution == 'Ubuntu'
apt模块，本地的deb文件，参数是deb，state参数没有installed状态的。name参数指定不到一个url，需要get_url将deb下载下来,dest指定目录，来安装
后记
若是很多的tasks写在一个yaml文件里面，太臃肿，不好维护，怎么解决呢？那么下次说说它的roles~~peace yo~
