环境

• Ubuntu 20.04

安装Ansible

apt install

sudo apt install ansible

markupsafe error

安装成功后，尝试运行ansible，部分环境下会有如下报错：

ubuntu@ubuntu:~$ ansible --version
Traceback (most recent call last):File "/usr/bin/ansible", line 62, in <module>import ansible.constants as CFile "/usr/lib/python3/dist-packages/ansible/constants.py", line 12, in <module>from jinja2 import TemplateFile "/usr/lib/python3/dist-packages/jinja2/__init__.py", line 33, in <module>from jinja2.environment import Environment, TemplateFile "/usr/lib/python3/dist-packages/jinja2/environment.py", line 15, in <module>from jinja2 import nodesFile "/usr/lib/python3/dist-packages/jinja2/nodes.py", line 23, in <module>from jinja2.utils import MarkupFile "/usr/lib/python3/dist-packages/jinja2/utils.py", line 656, in <module>from markupsafe import Markup, escape, soft_unicode
ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/home/ubuntu/.local/lib/python3.8/site-packages/markupsafe/__init__.py)

上述报错通常是markupsafe版本不兼容导致，查看markupsafe的版本：

ubuntu@ubuntu:~$ pip show markupsafe
Name: MarkupSafe
Version: 2.1.5

回退到2.0.1版本可以解决：

python -m pip install markupsafe==2.0.1

ansible可成功运行：

ubuntu@ubuntu:~$ ansible --version
ansible 2.9.6config file = /etc/ansible/ansible.cfgconfigured module search path = ['/home/ubuntu/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']ansible python module location = /usr/lib/python3/dist-packages/ansibleexecutable location = /usr/bin/ansiblepython version = 3.8.10 (default, Nov 22 2023, 10:22:35) [GCC 9.4.0]

配置Ansible

创建个人目录

为了不影响系统配置，可以在个人的自定义目录下运行ansible，基于个人的配置文件：

mkdir -p /home/ubuntu/mydir/ansible

ansible.cfg

拷贝系统的cfg文件到个人目录下进行修改：

cp /etc/ansible/ansible.cfg /home/ubuntu/mydir/ansible

修改cfg文件：

[defaults]
inventory      = /home/ubuntu/mydir/ansible/hosts[privilege_escalation]
become=True
become_method=sudo
become_user=root
become_ask_pass=False

hosts

拷贝系统的hosts文件到个人目录下进行修改：

cp /etc/ansible/hosts /home/ubuntu/mydir/ansible

修改hosts文件：

[my_test]
#10.5.3.202 ansible_ssh_port=22 ansible_ssh_user=test ansible_ssh_pass='123' ansible_su_pass='123'
10.5.3.202[my_test:vars]
ansible_ssh_user=test
ansible_ssh_pass="123"

测试Ansible

ping

测试受控主机的连通性：

ubuntu@ubuntu:~/mydir/ansible$ ansible my_test -m ping
10.5.3.202 | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": false,"ping": "pong"
}

批量执行自定义命令

常用命令

ansible my_test -m shell -a "bash xxx.sh"
ansible my_test -m copy -a "src=/home/ubuntu/xxx.sh dest=/home/test/ mode=775"
ansible my_test -m file -a "path=/home/test/xxx.sh group=test owner=test"
