1.安装并配置ansible,在控制节点上安装并配置ansible
(1)创建静态inventory文件/home/devops/ansible/inventory,要求如下:
servera属于dev组
serverb属于test和balancers组
serverc和serverd属于prod组
prod组属于Webserver组
(2)创建ansible配置文件/home/devops/ansible/ansible.cfg,要求如下:
使用/home/devops/ansible/inventory清单文件
角色role目录路径为/home/devops/ansible/roles
没有/home/devops/ansible目录需要先创建该目录
[kiosk@foundation0 ~]$ rht-vmctl start all
Error: bastion not started (is already running)
Error: workstation not started (is already running)
Error: servera not started (is already running)
Error: serverb not started (is already running)
Error: serverc not started (is already running)
Error: serverd not started (is already running)
[kiosk@foundation0 ~]$ ssh devops@workstation
Activate the web console with: systemctl enable --now cockpit.socket
Last login: Mon Jun 19 18:46:41 2023 from 172.25.250.250
[devops@workstation ~]$ mkdir /home/devops/ansible
到该目录下创建inventory文件,ansible.cfg文件,roles文件,参照/etc/ansible/ansible.cfg配置内容
[devops@workstation ~]$ cd /home/devops/ansible/
[devops@workstation ansible]$ ll
total 12
-rw-r--r--. 1 root root 114 Jun 19 19:19 ansible.cfg
-rw-r--r--. 1 root root 148 Jun 19 19:19 inventory
-rw-r--r--. 1 root root 1 Jun 19 19:03 roles
[devops@workstation ~]$ cat /etc/ansible/ansible.cfg
[devops@workstation ansible]$ cat ansible.cfg
[defaults]
inventory=/home/devops/ansible/inventory
roles_path=/home/devops/ansible/roles
host_key_checking=False
[devops@workstation ansible]$ cat inventory
[dev]
servera
[test]
serverb
[balancers]
serverb
[prod]
server[c:d]
[Webserver:children]
prod
[all:vars]
ansible_user=root
ansible_password=redhat
测试连通性
[devops@workstation ansible]$ ansible all -m ping
servera | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
serverd | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
serverc | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
serverb | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
2.创建并运行 Ansibie ad-hoc 命令
创建一个 shell 脚本名为 adhoc.sh 用以运行 ad-hoc 命令 . 为每个受控节点配罝 yum仓库. 要求如下:
仓库1:
Name:RH294_Base
Description:RH294 base software
Baseurl:http://content.example.com/rhel8.0/x86_64/dvd/BaseOS
需要验证钦件包GPG签名
GPG key:/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
启用此软件仓库
仓库2:
Name:RH294_Stream
Description:RH294 stream software
Base url: http://content.example.com/rhel8.0/x86_64/dvd/AppStream
需要验证软件包GPG签名
GPG key:/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
启用此软件仓库
[devops@workstation ansible]$ sudo vim adhoc.sh
#!/bin/bash
ansible all -m yum_repository -a 'name=RH294_Base \
description="RH294 base software" \
baseurl="http://content.example.com/rhel8.0/x86_64/dvd/BaseOS" \
gpgcheck=yes \
gpgkey=/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release \
enabled=yes'
ansible all -m yum_repository -a 'name=RH294_Stream \
description="RH294 stream software" \
baseurl="http://content.example.com/rhel8.0/x86_64/dvd/AppStream" \
gpgcheck=yes \
gpgkey=/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release \
enabled=yes'
[devops@workstation ansible]$ sudo chmod +x adhoc.sh
[devops@workstation ansible]$ ./adhoc.sh
