基于ansible在远程centos服务器docker环境安装docker-redis

本文档主要介绍如何使用ansible在远程centos服务器docker环境快速安装redis6.0.8，目标服务器为一台阿里云ECS，安装操作系统为阿里云提供的公共镜像Centos7.9-64。且已经预装docker环境。

准备

硬件

一台阿里云ECS：1c2g40g 预装docker环境 参考 基于ansible在centos服务器安装docker 一台可以连接阿里云的linux服务器，预装ansible和git，其中ansible版本为2.9.27

基础环境

安装

本地安装指ssh到主控端，然后通过ansible将redis容器在目标服务器上启动并运行。

下载脚本

[root@myhost ~]# git clone ansible-examples]# cd ..

验证

[root@server240 aliyun-centos7.9]# ansible -m shell -a '/usr/soft/python3/bin/python3 --version' -i hosts myhost myhost | CHANGED | rc=0 >> Python 3.6.13
