本文主要讲述如何使用Ansible在Redhat Linux系列上安装golang 19。

关于Ansible的基本概念可以参考运维自动化之Ansible

1. 安装Ansible

安装Ansible参考安装ansible | 鹏叔的技术博客

2. 编写Ansible Playbook

如果远程主机非root用户，需要准备一个ansible.cfg文件用于覆盖ansible默认配置，
也可以直接修改/etc/ansible/ansible.cfg

# vi ansible.cfg
[defaults]
# replace the user with actual user on controlled node
remote_user = user_name_on_managed_host

[privilege_escalation]
become = True
become_method = sudo
become_user = root
become_ask_pass = False

vi install_golang.yaml

- name: Install golang
  hosts: all
  become: yes
  vars: 
  - golang_download_url: https://studygolang.com/dl/golang/go1.19.3.linux-amd64.tar.gz
    env_file: /etc/profile

  tasks:
    - name: Unzip the downloaded file
        unarchive: 
        src:  "{{ golang_download_url }}" 
        dest: /usr/local
        remote_src: yes

    - name: Set Golang environment variables
        lineinfile: dest={{ env_file }} insertafter={{ item.position }} line={{ item.value }} state=present
        with_items:
        - {position: EOF, value: "export GOPROXY=https://goproxy.cn,direct"}
        - {position: EOF, value: "export PATH=$PATH:/usr/local/go/bin"}
        notify: Reload profile 

  handlers:
    - name: Reload profile
      shell: source {{ env_file }}

3. 执行Ansible Playbook

ansible-playbook install_golang.yaml
