centos 安装rabbitmq集群

本文介绍: 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。

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
```

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。

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
```
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

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
```

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：

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。

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。
