安装包是从官网下载的
https://gitee.com/GreatSQL/GreatSQL/releases/

我们提供的rpm包是for RHEL 8系统的，你的是欧拉，建议自己编译，兼容性会更好些。

日志中仍无法清晰定位失败原因，还需要补充提供其他节点的日志来确认。几个可能的原因：

1. 检查节点 .2 的 MGR 状态是否存活

有可能 172.41.12.2 这个实例挂了，或者它的 MGR 插件没有正常启动。

登录到 .2，执行：SELECT * FROM performance_schema.replication_group_members;

确认它处于 ONLINE 状态。

2. 排查网络和防火墙策略 (最常见原因)

两台机器之间可能存在网络隔离限制，导致 .3 访问不到 .2 的 33061 端口。

在当前的报错节点（.3）上执行以下命令测试连通性：

如果不通，请检查 .2 机器上的 iptables、firewalld 或云环境的安全组策略，确保放行了 TCP 33061 端口。

3. 检查节点 .2 的 IP Allowlist（白名单）配置

这是一个很容易踩坑的地方！虽然你在当前节点（.3）配置了允许 .1 和 .2，但组通信是双向的。

请务必去检查 172.41.12.2 的 my.cnf 配置，或者在 .2 上执行：

确保节点 .2 的白名单里包含了新节点 172.41.12.3 的 IP。如果没包含，.2 会主动切断 .3 发来的连接请求。
