环境准备

操作系统要求：centos8.x

Libc 要求

ls -l /lib64/libc.so.6

 """
  /lib64/libc.so.6 -> libc-2.28.so
 """

确定主运行 IP，所有 Ansible 部署操作都将在主运行 IP 上执行。在本例中，主运行 IP 为 172.20.3.200。

使用 IP 地址无密码登录

如果每台机器的密码相同，并且在清单/主机中使用了根用户名和密码，则无需执行以下步骤。

生成 SSH 公钥和私钥

ssh-keygen -f ~/.ssh/id_rsa -N '' -t rsa -q -b 2048

将公钥复制到所有主机节点，包括本地节点

ssh-copy-id root@ip
ssh-copy-id root@ip
ssh-copy-id root@ip

测试无密码登录是否成功

ssh root@ip

Ansible 安装

在线安装

 #Ensure that Python environment is installed on each machine using Python 3
 #Install Ansible on the main IP, if it is not already installed.
 
pip3 install pip -U
pip3 install ansible==2.9.27 # Install with fixed version number, non-mandatory

pip3 install pyopenssl -U

脱机安装

# Preparation of files:
wget -r -nH http://ip:9000  # Download all required package files with one click

ansible_installer_centos8.sh Place the files separately and proceed with Ansible installation
Place other files in the deployment package dingo-deploy/artifacts directory

#  Installing Ansible requires root user
bash ansible_installer_centos8.sh # This needs to be executed on all three machines to ensure that the path to Python 3 is consistent on each machine

#Note to modify inventory/hosts before deployment
ansible_python_interpreter=/usr/local/miniconda3/bin/python

# Replace all Ansible and Python commands below with full path, for example:
/usr/local/miniconda3/bin/ansible-playbook playbook.yml
