absible部署
1、配置yum仓库
[root@ansible ~]# mount /dev/cdrom /mnt/
[root@ansible ~]# cd /etc/yum.repos.d/
[root@ansible ~]# vim server.repo
2、安装软件包组
[root@ansible ~]# yum -y group install "Virtualization Client" "Virtualization Hypervisor" "Virtualization Tools"
3、重启libvirtd服务，并设置下次启动生效
[root@ansible ~]# systemctl restart libvirtd
[root@ansible ~]# systemctl enable libvirtd
4、将本地RHEL9.2镜像上传到虚拟机
5、virt-manager打开虚拟监视器进行安装系统
[root@ansible ~]# virt-manager
6、配置网络的yum仓库
6.1 安装httpd服务
[root@ansible ~]# yum -y install httpd
6.2 上传软件包到/var/www/html/
6.3 重启httpd服务
[root@ansible ~]# systemctl restart httpd
[root@ansible ~]# systemctl enable httpd
7.在master写域名解析
[root@master ~]# vi /etc/hosts
8、在ansible写域名解析
[root@ansible ~]# vim /etc/hosts
9、配置master的yum仓库
[root@master yum.repos.d]# vi server.repo
9.1安装软件测试
[root@master ~]# yum -y install vim bash-completion net-tools
[root@master ~]# bash #应用工具
10、克隆出来5台，+刚刚安装的一台，一起6台主机
10.1以此方法创建node1、node2、node3、node4、node5
10.2所有主机，配置IP的时候注意一下，要删除网卡配置文件的UUID,
node1:
[root@master ~]# hostnamectl hostname node1.example.com
[root@master ~]# bash
[root@node1 ~]# vim /etc/NetworkManager/system-connections/enp1s0.nmconnection
删除UUID,
address1=192.168.122.10/24,192.168.122.1
[root@node1 ~]# systemctl restart NetworlManager
[root@node1 ~]# nmcli connetion up enp1s0
[root@node1 ~]# rm -rf /etc/yum/repos.d/server/repo
node2:
[root@master ~]# hostnamectl hostname node2.example.com
[root@master ~]# bash
[root@node2 ~]# vim /etc/NetworkManager/system-connections/enp1s0.nmconnection
删除UUID,
address1=192.168.122.20/24,192.168.122.1
[root@node2 ~]# systemctl restart NetworlManager
[root@node2 ~]# nmcli connetion up enp1s0
[root@node2 ~]# rm -rf /etc/yum/repos.d/server/repo
依次配置node3、4、5
11、配置master主机的免密钥登录
root:
11.1 root免密钥
[root@master ~]# ssh-keygen
11.2 密钥分发node1~node5
[root@master ~]# for i in node{1..5}
> do ssh-copy-id -i ~/.ssh/id_rsa.pub root@$i
> done
11.3 密钥发给student用户
[root@master ~]# for i in node{1..5}; do ssh-copy-id -i ~/.ssh/id_rsa.pub student@$i; done
student
11.4 student免密钥
[root@master ~]# su - student
[student@master ~]$ ssh-keygen
11.5 密钥分发node1~node5
[student@master ~]$ for i in node{1..5}; do ssh-copy-id -i ~/.ssh/id_rsa.pub root@$i; done
11.6 密钥发给student用户
[student@master ~]$ for i in node{1..5}; do ssh-copy-id -i ~/.ssh/id_rsa.pub student@$i; done
12 、权限委派，给student权限
[root@master ~]# vim /etc/sudoers.d/student
12.1 传输到node(1~5)
[root@master ~]# for i in node{1..5}
> do scp /etc/sudoers.d/student root@$i:/etc/sudoers.d/
> done
13、安装ansible
[root@master ~]# yum -y install ansible-core ansible-navigator
14、配置ansible
[root@master ~]# su - student
[student@master ~]$ mkdir ansible/
[student@master ~]$ cd ansible/
[student@master ansible]$ ansible-config init --disabled > ansible.cfg
[student@master ansible]$ vim ansible.cfg
14.1 开启主机清单
[student@master ansible]$ vim ansible.cfg
[student@master ansible]$ vim inventory
14.2 新建角色roles目录和collections目录
[student@master ansible]$ mkdir roles
[student@master ansible]$ mkdir collections
[student@master ansible]$ vim ansible.cfg
14.3关闭更换主机时的提示语
14.4 ansible提权
15、测试主机是否关联
注意一定要在这个目录下测试
[student@master ansible]$ pwd
/home/student/ansible
测试：
[student@master ansible]$ ansible all -m ping
