在ansible on clouds部署mesh

在azure创建aap 2.4

选择public模式，方便访问aap

在azure创建hop和exec node

2个node使用的rhel9.5
创建exec node时选择不同的vnet，确保2个node之间的子网不重叠，以免ip冲突，hop无法连接exec

配置hop node和exec node

sudo subscription-manager register --auto-attach
sudo subscription-manager repos --enable ansible-automation-platform-2.4-for-rhel-9-x86_64-rpms
sudo dnf install -y ansible-core
sudo firewall-cmd --permanent --zone=public --add-port=27199/tcp

配置hop node ssh免登录到exec node

ssh-keygen -t rsa -b 4096
ssh-copy-id -i ~/.ssh/id_rsa.pub ssli@exec_node
ssh-copy-id -i ~/.ssh/id_rsa.pub ssli@hop_node
# 在exec node执行
ssh-keygen -t rsa -b 4096
ssh-copy-id -i ~/.ssh/id_rsa.pub ssli@exec_node

配置automation controller

参考这个文章配置automation controller：https://www.redhat.com/en/blog/deploying-automation-mesh-ansible-clouds

配置hop和exec node

参考这个文档配置hop和exec node：https://www.redhat.com/en/blog/deploying-automation-mesh-ansible-clouds

网络配置

aap到hop node的双向peering
hop node到exec node的双向peering
hop node到exec node的网络安全组中打开相应的端口22和27199

故障排查

重启hop node和exec node
重启controller pod
在credentials添加exec node的登录用户和密码用于执行作业
增加磁盘空间

确认automation mesh

在controller的instances页面，hop node和exec node状态都是ready。
