配置文件

#放自己home更加爽
/home/evan/ansible

so   Jul 04  2023

sudo vi /etc/ansible/ansible.cfg
[defaults]
inventory = /home/evan/ansible/inventory/hosts




# 写在自己的home目录 
ansible在使用配置文件时按照以下顺序优先配置：

export ANSIBLE_CONFIG

./ansible.cfg

~/.ansible.cfg

/etc/ansible/ansible.cfg

如果以上顺序没有找到配置文件ansible会自动使用默认配置

关于ansible的配置在/etc/ansible/ansible.cfg文件中，所以关于ansible运行时所使用的ssh配置也可以在此文件中配置。在目前的ansible中，运行ansible时会依次加载 环境变量ANSIBLE_CONFIG，当前目录的ansible.cfg，~/.ansible.cfg，/etc/ansible/ansible.cfg，针对同一个配置项以最先加载到的为准。所以，我们可以单独编写自己的ansible.cfg文件放在当前目录下。

可以去github上把默认配置拿下来：

https://raw.githubusercontent.com/ansible/ansible/devel/examples/ansible.cfg
# To generate an example config file (a "disabled" one with all default settings, commented out):
#               $ ansible-config init --disabled > ansible.cfg

# Also you can now have a more complete file by including existing plugins:
# ansible-config init --disabled -t all > ansible.cfg

把它放到/etc/ansible/目录

ansible指定用户

方案1：
nsible -m ping -u 用户名

方案2：

修改/etc/ansible/hosts文件：
[test_hosts]
host_ip ansible_user=用户名
# 还可以指定登陆密码
host_ip ansible_user=用户名 ansible_ssh_pass=登陆密码

日常技巧

sudo

sudo 详细例子insdocker在github

没密码的sudo

cat /etc/ansible/agent.yml
---
- hosts: all
  become: yes
  become_method: sudo
  remote_user: evan  
  #remote_user: ops 
  roles:
    - ag_conf

#当然 shell 里面也要写sudo 

#直接在commond 这样执行,要交互,但是可以直接回车 如果没密码
ansible  tmp -m  command -a "ls /root"  -u  evan --become  --ask-become-pass

ansible 普通用户执行命令


Ansible 使用普通用户远程执行playbook

https://stackoverflow.com/questions/38958333/how-to-achieve-sudo-su-user-and-run-all-command-in-ansible#38965192

SSH authenticity checking

Is there a way to ignore the SSH authenticity checking made by Ansible? For example when I've just setup a new server I have to answer yes to this question:

GATHERING FACTS ***************************************************************
The authenticity of host 'xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx)' can't be established.
RSA key fingerprint is xx:yy:zz:....
Are you sure you want to continue connecting (yes/no)?


方法1 直接在命令行 加参数 
 ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook   ssh-u-conf.yml

方法2  加到配置文件 
/etc/ansible/ansible.cfg or ~/.ansible.cfg

[defaults]
host_key_checking = False

https://stackoverflow.com/questions/32297456/how-to-ignore-ansible-ssh-authenticity-checking

分组

ansible beta -b -u evan -m shell   -a " sudo hostname"
执行ansible-playbook  -C /etc/ansible/agent.yml 得在 yml 里面指定 hostip etc

-u REMOTE_USER	#远程用户，默认为 root 用户

查看列表的命令
-m	要执行的模块，默认为command

变量

# 主机和主机组变量(主机变量优先级大于主机组变量)

vim /etc/ansible/hosts

[webservers]

172.16.1.121:22 ansible_ssh_user=root ansible_ssh_pass='123456' http_port=80

172.16.1.122:22 ansible_ssh_user=root ansible_ssh_pass='123456'


[webservers:vars]
http_port=8080
server_name=www.baidu.com

实验：

ansible webservers -m command -a "echo {{http_port}}" -o

命令说明：

ansible webservers -m command -a "echo {{http_port}}" -o

ansible：ansible命令

webservers：/etc/ansible/hosts中配置的主机组名称，指定 all (分组和未分组的主机)代表所有主机，指定172.16.1.121代表单台主机。

-m：指定使用的模块，默认是command模块(简单的shell命令)，可以省略不写。

-a：指定具体使用的shell指令，比如"echo {{http_port}}"表示在远程主机上打印http_port这个变量。

-o：对ansible的输出的结果进行压缩(即，输出的结果显示在一行)

远程执行shell脚本文件

Friday July twenty-ninth 2022

编写脚本

cat /tmp/mypatch 
# 卸载旧版本
yum remove -y kubelet kubeadm kubectl

# 安装kubelet、kubeadm、kubectl
# 将 ${1} 替换为 kubernetes 版本号，例如
v=1.21.12
yum install -y kubelet-${v} kubeadm-${v} kubectl-${v}
crictl config runtime-endpoint /run/containerd/containerd.sock
# 重启 docker，并启动 kubelet
systemctl daemon-reload
systemctl enable kubelet && systemctl start kubelet

脚本copy到其他几台服务器

#执行ansible命令，将脚本copy到其他几台服务器上
  ansible  myk8s -u root -m copy -a "src=/tmp/mypatch dest=/tmp/mypatch"

每台服务器上执行 你的shell脚本

#执行ansible命令，在每台服务器上执行 你的shell脚本
ansible  myk8s -u root -m shell -a "bash /tmp/mypatch chdir=/tmp"

[WARNING]: A duplicate localhost-like entry was found (localhost). First found localhost was 127.0.0.1
127.0.0.1 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}

command 模块

 ansible web -m command -a 'ss -ntl'

命令模块接受命令名称，后面是空格分隔的列表参数。给定的命令将在所有选定的节点上执行。它不会通过shell进行处理，比如$HOME和操作如"<"，">"，"|"，";"，"&" 工作（需要使用（shell）模块实现这些功能）。注意，该命令不支持| 管道命令。
　　下面来看一看该模块下常用的几个命令：

    chdir　　　　　　 # 在执行命令之前，先切换到该目录
    executable # 切换shell来执行命令，需要使用命令的绝对路径
    free_form 　 # 要执行的Linux指令，一般使用Ansible的-a参数代替。
    creates 　# 一个文件名，当这个文件存在，则该命令不执行,可以
    用来做判断
    removes # 一个文件名，这个文件不存在，则该命令不执行

shell 模块

shell模块基本和command相同，但是shell raw支持管道符

➜  ~ ansible pi3 -m raw -a "cat /etc/passwd | wc -l"
192.168.10.5 | CHANGED | rc=0 >>
41
Shared connection to 192.168.10.5 closed.

➜  ~ ansible pi3 -m shell  -a "cat /etc/passwd | wc -l"
192.168.10.5 | CHANGED | rc=0 >>
41



shell > ansible Client -m shell -a "/home/test.sh"           # 执行远程脚本


cat /root/2
touch 2.txt

ansible 200  -b -u evan -m shell   -a  "sudo bash  /home/evan/close"

# cat /home/evan/2.txt 用sudo 默认去了 evan

copy 模块

 ansible  myk8  -m copy -a 'dest=/home/evan src=/tmp/vboxdrv-Module.symvers'  #把 master上的 /tmp/vboxdrv-Module.symvers  cp到 myk8组的所有机器的 /home/evan下

fetch 模块

和copy 相反 ,可看作文件上传动作,  把 远端机器的 /home/evan/vboxdrv-Module.symvers 收集回主机的 /home/evan/tmp/tpp目录下 
  ansible  myk8 -m fetch -a 'dest=/home/evan/tmp/tpp  src=/home/evan/vboxdrv-Module.symvers'

file

还有相关的什么权限 用户组 属性什么的
ansible  myk8  -m file -a  'path=/home/evan/vboxdrv-Module.symvers  state=absent' #删除/home/evan/vboxdrv-Module.symvers

9）service 模块

该模块用于服务程序的管理。
　　其主要选项如下：

    arguments #命令行提供额外的参数
    enabled #设置开机启动。
    name= #服务名称
    runlevel #开机启动的级别，一般不用指定。
    sleep #在重启服务的过程中，是否等待。如在服务关闭以后等待2秒再启动。(定义在剧本中。)
    state #有四种状态，分别为：started--->启动服务， stopped--->停止服务， restarted--->重启服务， reloaded--->重载配置

　　下面是一些例子：
① 开启服务并设置自启动

[root@server ~]# ansible web -m service -a 'name=nginx state=started enabled=true'

12）script 模块 运行sh or py 2023 update

script模块将控制节点的脚本执行在被控节点上。 相当于scp+shell

➜  ~ hostname
myxps
➜  ~ cat /tmp/hostname 
hostname
➜  ~ 
➜  ~ ansible pi3 -m  script -a /tmp/hostname 
192.168.10.5 | CHANGED => {
    "changed": true,
    "rc": 0,
    "stderr": "Shared connection to 192.168.10.5 closed.\r\n",
    "stderr_lines": [
        "Shared connection to 192.168.10.5 closed."
    ],
    "stdout": "mypi3b\r\n",
    "stdout_lines": [
        "mypi3b"
    ]
}
➜  ~ 




  一般用在被管主机上 执行一系列命令就非常爽
一般先用copy 把脚本下发到所有的 slave机器 再执行

#Dec thirteenth 2022

ansible的script模块的用途

script 模块用来在远程主机上执行 ansible 管理主机上的脚本，

即：脚本一直存在于 ansible 管理主机本地，

不需要手动拷贝到远程主机后再执行

➜  tmp cat a.sh 
touch  evantouch.txt

chmod +x /home/evan/tmp/a.sh

ansible intra  -u root  -m  script -a '/home/evan/tmp/a.sh'

ansible intra    -m  script -a '/home/evan/tmp/a.sh' --become  --become-method=sudo --become-user=root
 
 执行效果 
 -192-168-10-121-c7 ~] {16:35:22} (0)
# ls /root/evantouch.txt 
/root/evantouch.txt


根据文件判断是否需要执行脚本?

creates参数 ：使用此参数指定一个远程主机中的文件，当指定的文件存在时，就不执行对应脚本
removes参数 ：使用此参数指定一个远程主机中的文件，当指定的文件不存在时，就不执行对应脚本

[root@centos8 ~]# ansible yujian -m script -a 'removes=/root/isgit.txt /home/liuhongdi/ansible/gitpubwww.sh'  --become  --become-method=sudo --become-user=root
121.122.123.47 | SKIPPED

因为删除文件不成功，所以不执行

[root@centos8 ~]# ansible yujian -m script -a 'creates=/root/isgit.txt /home/liuhongdi/ansible/gitpubwww.sh'  --become  --become-method=sudo --become-user=root
121.122.123.47 | CHANGED => {
    "changed": true,
...

因为文件可以创建，所以成功执行

firewalld模块


service ： Name of a service to add/remove to/from firewalld.The service must be listed in output of firewall-cmd --get-services.
指定放行的服务，此服务必须要在firewall-cmd --get-services查询的到。

irewalld模块主要设置火墙对服务和端口的允许
参数：ansible-doc -s firewalld查看一下fetch模块的参数`

service参数 	必须参数，用于指定要允许服务。
state参数 	enabled开机启动
permanent参数 	true 永久添加
immediate参数 	true 立即生效








#  firewall-cmd --list-all
public
  target: default
  icmp-block-inversion: no
  interfaces: 
  sources: 
  services: dhcpv6-client ssh
  
  
  /etc/ansible# cat fire.yml

ansible and shell

使用ansible执行shell命令的正确姿势

ansible-galaxy

ansible-galaxy install docker

  ansible-galaxy install geerlingguy.docker #记得国内机器可能要改dns 为8.8.4.4 不然连接github time out

#主要配置文件 
root@myxps:~# cat ~/.ansible/roles/geerlingguy.docker/defaults/main.yml 


 cat pb-docker.yml  #安装 docker 
- hosts: mydocker
  vars:
    docker_users:
      - root
  roles:
    - role: geerlingguy.docker
      become: yes


ansible-playbook -u root pb_docker.yml

通过 Ansible 安装 Docker

分发文件

 

 cat /etc/ansible/hosts
[intra]
192.168.10.120
192.168.10.121



ansible intra -m copy -a "src=/home/evan/data/devops/node-v14.17.6-linux-x64.tar.xz  dest=/root/"

ansible 122 -m copy -a "src=/home/evan/data/devops/jdk/jdk-8u212-linux-x64.rpm dest=/root/"

ansible批量传输文件

结合P2P软件使用Ansible分发大文件_神棍之路-程序员宅基地

使用 Ansible 传输文件的几种方式

solution
忘记main.yml 加上 copy.yml喽


普通用户  

$ ansible
Traceback (most recent call last):
  File "/usr/local/bin/ansible", line 32, in <module>
    from ansible import context
ModuleNotFoundError: No module named 'ansible'


evan@myxps:~/data/resume/interview$ pip list   | grep ansible

ansible中配置ssh--ssh连接断开时，如何很快获取异常并中断playbook的执行

[DEPRECATION WARNING]: "include" is deprecated, use include_tasks/import_tasks instead. This feature will be removed

把你的 tasks/main.yml include 换成  include_tasks/import_tasks 就可以了
