当然，我会提供一个更加详细的步骤指南，帮助你在三台 CentOS 服务器上搭建 RabbitMQ 集群。这些服务器的 IP 地址分别为 10.206.0.4、10.206.0.8 和 10.206.0.13。
步骤 1: 安装 Erlang
RabbitMQ 需要 Erlang 运行环境。在每台服务器上执行以下步骤：
-
添加 Erlang 仓库:
sudo yum install -y epel-release sudo yum install -y https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm -
安装 Erlang:
sudo yum install -y erlang -
验证 Erlang 安装:
erl -version
步骤 2: 安装 RabbitMQ
接下来，在每台服务器上安装 RabbitMQ：
-
添加 RabbitMQ 仓库:
sudo rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc sudo yum install -y https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.9/rabbitmq-server-3.8.9-1.el7.noarch.rpm -
安装 RabbitMQ:
sudo yum install -y rabbitmq-server -
启动 RabbitMQ 服务并设置开机自启:
sudo systemctl start rabbitmq-server sudo systemctl enable rabbitmq-server -
启用 RabbitMQ 管理控制台（可选）:
sudo rabbitmq-plugins enable rabbitmq_management -
重启 RabbitMQ 服务:
sudo systemctl restart rabbitmq-server
步骤 3: 设置 Hostname 和 /etc/hosts
在每台服务器上执行以下步骤，以确保节点之间能够相互识别：
-
设置每台服务器的 Hostname:
- 在 10.206.0.4 上：
sudo hostnamectl set-hostname node1 - 在 10.206.0.8 上：
sudo hostnamectl set-hostname node2 - 在 10.206.0.13 上：
sudo hostnamectl set-hostname node3
- 在 10.206.0.4 上：
-
更新每台服务器的 /etc/hosts 文件:
- 在每台服务器上，添加以下行：
10.206.0.4 node1 10.206.0.8 node2 10.206.0.13 node3 - 你可以使用
sudo vi /etc/hosts来编辑文件。
- 在每台服务器上，添加以下行：
步骤 4: 配置和启动 RabbitMQ 集群
-
在 node1 上创建一个集群:
RabbitMQ 服务已经在前面的步骤中启动。 -
复制 Erlang Cookie:
- Erlang Cookie 用于节点之间的身份验证。从 node1 复制
.erlang.cookie文件到 node2 和 node3：scp /var/lib/rabbitmq/.erlang.cookie root@node2:/var/lib/rabbitmq/ scp /var/lib/rabbitmq/.erlang.cookie root@node3:/var/lib/rabbitmq/ - 确保在 node2 和 node3 上的
/var/lib/rabbitmq/.erlang.cookie文件权限为 400：sudo chmod 400 /var/lib/rabbitmq/.erlang.cookie
- Erlang Cookie 用于节点之间的身份验证。从 node1 复制
-
在 node2 和 node3 上加入集群:
- 在 node2 和 node3 上，停止 RabbitMQ 服务：
sudo systemctl stop rabbitmq-server - 清除 mnesia 数据库：
sudo rm -rf /var/lib/rabbitmq/mnesia/* - 重新启动 RabbitMQ 服务：
sudo systemctl start rabbitmq-server - 将 node2 和
- 在 node2 和 node3 上，停止 RabbitMQ 服务：
node3 加入到集群：
- 在 node2 上：bash sudo rabbitmqctl stop_app sudo rabbitmqctl join_cluster rabbit@node1 sudo rabbitmqctl start_app
- 在 node3 上，重复上述步骤，但将 join_cluster 命令中的 rabbit@node1 改为 rabbit@node2。
-
检查集群状态:
- 在任何节点上执行以下命令来检查集群状态：
sudo rabbitmqctl cluster_status
- 在任何节点上执行以下命令来检查集群状态：
步骤 5: 设置镜像队列（可选）
如果你想要增强数据的持久性和高可用性，你可以设置镜像队列：文章来源：https://www.toymoban.com/news/detail-810721.html
sudo rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all","ha-sync-mode":"automatic"}'
这将应用于所有队列，使它们在集群的所有节点上都有镜像。文章来源地址https://www.toymoban.com/news/detail-810721.html
注意事项
- 确保在所有服务器上正确设置了 Erlang Cookie，并且文件权限正确。
- 在配置集群之前，确保所有 RabbitMQ 节点可以相互网络通信。
- 如果在集群配置过程中遇到问题，请检查 RabbitMQ 日志文件以获取更多信息。日志文件通常位于
/var/log/rabbitmq/。 - 保持集群中所有 RabbitMQ 节点的版本一致。
