> 如果需要修改，记得修改网关和IP地址。
|
||||
|
||||
看自己是否有这个需求。

```yaml
|
||||
network:
|
||||
ethernets:
|
||||
ens33:
|
||||
dhcp4: false
|
||||
addresses: [192.168.3.144/24]
|
||||
optional: true
|
||||

应用修改
|
||||
|
||||
```bash
|
||||
sudo netplan apply
|
||||
# or
|
||||
sudo reboot
|
||||
```
|
||||
|
||||
### Docker方式
|
||||
|
||||
集群环境搭建版本是：
|
||||
|
||||
#### 1、配置docker镜像源
|
||||
|
||||
```bash
|
||||
# 创建目录
|
||||
sudo mkdir -p /etc/docker
|
||||
# 写入配置文件
|
||||
sudo tee /etc/docker/daemon.json <<-'EOF'
|
||||
{
|
||||
"registry-mirrors": [
|
||||
"https://docker-0.unsee.tech",
|
||||
"https://docker-cf.registry.cyou",
|
||||
"https://docker.1panel.live"
|
||||
]
|
||||
}
|
||||
EOF
|
||||
# 重启docker服务
|
||||
sudo systemctl daemon-reload && sudo systemctl restart docker
|
||||
```
|
||||
|
||||
#### 2、docker-compose.yaml
|
||||
|
||||
> [!IMPORTANT]
|
||||
>
|
||||
> 执行前确保有权限！！！
|
||||
>
|
||||
> ```bash
|
||||
> # 1. 停止容器
|
||||
> docker compose stop
|
||||
>
|
||||
> # 2. 清理旧目录（可选）
|
||||
> sudo rm -rf ~/docker/docker_data/rabbitmq
|
||||
>
|
||||
> # 3. 重建目录并设置权限
|
||||
> mkdir -p ~/docker/docker_data/rabbitmq/{rabbit1,rabbit2,rabbit3}/{data,conf,log}
|
||||
> sudo chown -R 999:999 ~/docker/docker_data/rabbitmq
|
||||
> sudo chmod -R 775 ~/docker/docker_data/rabbitmq
|
||||
>
|
||||
> # 4. 重新启动
|
||||
> docker compose up -d
|
||||
> ```
|
||||
|
||||
创建文件：`docker-compose.yaml`。

```
|
||||
|
||||
#### 4、加入集群

|
||||
|
||||
```bash

### 普通方式
|
||||
|
||||
#### 先决条件
|
||||
|
||||
> [!TIP]
|
||||
>
|
||||
> 所有节点使用相同版本的Erlang（可通过`erl -version`检查）
|
||||
|
||||
- 至少两台Ubuntu服务器（建议18.04 LTS或更高版本）
|
||||
- 所有服务器之间网络互通
|
||||
- 每台服务器上已安装相同版本的RabbitMQ
|
||||
- 所有节点使用相同版本的Erlang
|
||||
|
||||
#### 1、安装RabbitMQ
|
||||
|
||||
在所有节点上执行以下步骤：
|
||||
|
||||
```bash
|
||||
# 更新软件包列表
|
||||
sudo apt update
|
||||
|
||||
# 安装必要的依赖
|
||||
sudo apt install -y curl gnupg
|
||||
|
||||
# 移除之前添加的 packagecloud.io 仓库
|
||||
sudo rm /etc/apt/sources.list.d/rabbitmq.list
|
||||
|
||||
# 添加 RabbitMQ 官方仓库密钥
|
||||
sudo apt-get install curl gnupg apt-transport-https -y
|
||||
|
||||
## Team RabbitMQ's main signing key

|
||||
|
||||
## Cloudsmith: modern Erlang repository
|
||||
curl -1sLf "https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/gpg.E495BB49CC4BBE5B.key" | sudo gpg --dearmor | sudo tee /usr/share/keyrings/io.cloudsmith.rabbitmq.E495BB49CC4BBE5B.gpg > /dev/null
|
||||
|
||||
## Cloudsmith: RabbitMQ repository

||||
# 启动RabbitMQ服务
|
||||
sudo systemctl start rabbitmq-server
|
||||

|
||||
|
||||
# 检查状态
|
||||
sudo systemctl status rabbitmq-server
|
||||
```
|
||||
|
||||
#### 2、配置主机名和hosts文件
|
||||
|
||||
> [!CAUTION]
|
||||
>
|
||||
> 所有主机上的`hostname`都必须和配置的一样，否则无法加入集群还会报错。
|
||||
>
|
||||
> 查看本机的hostname；如果输出的和配置的hosts的不一致，需要修改hostname。
|
||||
>
|
||||
> ```bash
|
||||
> # 查看本机的hostname
|
||||
> hostname
|
||||
>
|
||||
> # 永久修改hostname（以rabbit1为例）
|
||||
> sudo hostnamectl set-hostname rabbit1
|
||||
> ```
|
||||
>
|
||||
> **例如：**
|
||||
>
|
||||
> - 主节点hostname为rabbit1
|
||||
> - 192.168.3.145节点hostname为rabbit2
|
||||
> - 192.168.3.146节点hostname为rabbit3
|
||||
> - 以此类推
|
||||
|
||||
在所有节点上编辑`/etc/hosts`文件，确保包含所有集群节点的IP和主机名：
|
||||
|
||||
```bash
|
||||
sudo vim /etc/hosts
|
||||
```
|
||||
|
||||
添加类似以下内容（根据您的实际IP和主机名修改）：
|
||||
|
||||
```bash
|
||||
192.168.3.144 rabbit1
|
||||
192.168.3.145 rabbit2
|
||||
192.168.3.146 rabbit3
|
||||
192.168.3.147 rabbit4
|
||||
```
|
||||
|
||||
#### 3、设置Erlang Cookie
|
||||
|
||||
RabbitMQ节点使用Erlang cookie进行认证，所有节点必须使用相同的cookie。
|
||||
|
||||
如果是克隆的虚拟机，可以不检查（最好还是检查下），因为克隆的基本上是一样的。
|
||||
|
||||
选择一个节点作为主节点，将其cookie复制到其他节点：
|
||||
|
||||
```bash
|
||||
# 在主节点上查看cookie
|
||||
sudo cat /var/lib/rabbitmq/.erlang.cookie
|
||||
|
||||
# 在其他节点上停止RabbitMQ服务
|
||||
sudo systemctl stop rabbitmq-server
|
||||
|
||||
# 编辑或创建cookie文件
|
||||
sudo nano /var/lib/rabbitmq/.erlang.cookie
|
||||
|
||||
# 粘贴主节点的cookie内容
|
||||
# 然后设置正确的权限
|
||||
sudo chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
|
||||
sudo chmod 400 /var/lib/rabbitmq/.erlang.cookie
|
||||
|
||||
# 重新启动RabbitMQ服务
|
||||
sudo systemctl start rabbitmq-server
|
||||
```
|
||||
|
||||
#### 4、加入集群
|
||||
|
||||
> [!NOTE]
|
||||
>
|
||||
> 加入集群时，必须要是这样的格式`sudo rabbitmqctl join_cluster rabbit@主节点名称`
|
||||
|
||||
在非主节点上执行以下命令加入集群：
|
||||
|
||||
> [!WARNING]
|
||||
> `reset`命令会清除该节点的所有数据和配置，生产环境慎用
|
||||
|
||||
```bash
|
||||
# 停止RabbitMQ应用（不停止服务）
|
||||
sudo rabbitmqctl stop_app
|
||||
|
||||
# 重置节点（如果是新安装可以跳过，生产环境谨慎使用）
|
||||
sudo rabbitmqctl reset
|
||||
|
||||
# 加入集群（将rabbit1替换为您的主节点主机名）
|
||||
sudo rabbitmqctl join_cluster rabbit@rabbit1
|
||||
|
||||
# 启动RabbitMQ应用
|
||||
sudo rabbitmqctl start_app
|
||||
```
|
||||
|
||||
> [!CAUTION]
|
||||
>
|
||||
> 如果因为别的原因弄乱了，可以删除原来数据
|
||||
>
|
||||
> 仔细甄别下面是否有你需要的！！！
|
||||
>
|
||||
> ```bash
|
||||
> # 停止 RabbitMQ
|
||||
> sudo systemctl stop rabbitmq-server
|
||||
>
|
||||
> # 删除旧数据
|
||||
> sudo rm -rf /var/lib/rabbitmq/mnesia/
|
||||
>
|
||||
> # 确保 cookie 与其他节点一致
|
||||
> sudo cat /var/lib/rabbitmq/.erlang.cookie # 必须与其他节点相同
|
||||
>
|
||||
> # 启动服务
|
||||
> sudo systemctl start rabbitmq-server
|
||||
>
|
||||
> # 加入集群（使用新主机名）
|
||||
> sudo rabbitmqctl stop_app
|
||||
> sudo rabbitmqctl reset
|
||||
> sudo rabbitmqctl join_cluster rabbit@rabbit1 # 假设 rabbit1 是主节点
|
||||
> sudo rabbitmqctl start_app
|
||||
> ```
|
||||
|
||||
#### 5、验证集群状态
|
||||
|
||||
在任何节点上执行以下命令检查集群状态：
|
||||
|
||||
```bash
|
||||
sudo rabbitmqctl cluster_status
|
||||
|
||||
# OR 查看集群节点列表
|
||||
sudo rabbitmqctl cluster_status | grep -A10 'running_nodes'
|
||||
|
||||
# 检查服务状态
|
||||
sudo rabbitmqctl status
|
||||
```
|
||||
|
||||
> 为了提高可用性，可以设置镜像队列策略：
|
||||
>
|
||||
> ```bash
|
||||
> sudo rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'
|
||||
> ```
|
||||
|
||||
#### 6、启用管理插件（可选）
|
||||
|
||||
- 如果需要Web管理界面：
|
||||
|
||||
```bash
|
||||
sudo rabbitmq-plugins enable rabbitmq_management
|
||||
```
|
||||
|
||||
然后可以通过`http://<node-ip>:15672`访问，默认用户名/密码为`guest/guest`（建议更改）。
|
||||
|
||||
如果需要开启防火墙
|
||||
|
||||
```bash
|
||||
# 开放15672端口（如果使用防火墙）
|
||||
sudo ufw allow 15672/tcp
|
||||
```
|
||||
|
||||
> [!TIP]
|
||||
>
|
||||
> 如果到页面中查看，没有用户或者没有权限可以通过下面方式进行更改或添加。
|
||||
|
||||
如果需要添加用户，在你安装管理界面的机器上运行。
|
||||
|
||||
```bash
|
||||
# 如果存在可以先删除
|
||||
sudo rabbitmqctl delete_user 用户名
|
||||
|
||||
# 添加用户
|
||||
sudo rabbitmqctl add_user 用户名 密码
|
||||
|
||||
#设置用户操作权限
|
||||
sudo rabbitmqctl set_user_tags 用户名 administrator
|
||||
```
|
||||
|
||||
**示例**
|
||||
|
||||
```bash
|
||||
# 如果存在可以先删除
|
||||
sudo rabbitmqctl delete_user admin
|
||||
|
||||
# 添加用户
|
||||
sudo rabbitmqctl add_user admin admin
|
||||
|
||||
#设置用户操作权限
|
||||
sudo rabbitmqctl set_user_tags admin administrator
|
||||
```
|
||||
|
||||
- **修改配置文件**（如 `/etc/hosts`、防火墙规则等）需在所有节点操作。
|
||||
- **重启 RabbitMQ 服务**（如果修改了核心配置）：
|
||||
|
||||
```bash
|
||||
sudo systemctl restart rabbitmq-server
|
||||
```
|
||||
|
||||
### 常见问题
|
||||
|
||||
Q：打开主界面没有用户可以登录。
|
||||
|
||||
A：添加或者创建新用户，参考【普通方式->第六点】
|
||||
|
||||
Q：打开之后显示【⚠ All stable feature flags must be enabled after completing an upgrade. 】
|
||||
|
||||
```bash
|
||||
# 查看当前 Feature Flags 状态
|
||||
sudo rabbitmqctl list_feature_flags
|
||||
|
||||
# 启用所有稳定的 Feature Flags，这会启用所有 稳定（stable） 的功能标志（不包括实验性功能）。
|
||||
sudo rabbitmqctl enable_feature_flag all
|
||||
|
||||
# 检查是否成功启用
|
||||
sudo rabbitmqctl list_feature_flags
|
||||
|
||||
# 重启 RabbitMQ（可选）
|
||||
sudo systemctl restart rabbitmq-server
|
||||
```
|
||||
|
||||
Q：出现下面情况【Node statistics not available】
|
||||
|
||||
|
||||
|
||||
A：解决方法
|
||||
|
||||
**情况一 管理插件未在所有节点启用**
|
||||
|
||||
```bash
|
||||
sudo rabbitmq-plugins enable rabbitmq_management
|
||||
sudo systemctl restart rabbitmq-server
|
||||
```
|
||||
|
||||
**情况二 **
|
||||
|
||||
如果节点之间无法正常通信（如防火墙、网络策略阻止），管理界面无法获取其他节点的统计信息。
|
||||
|
||||
**检查方法**
|
||||
|
||||
在任意节点执行：
|
||||
|
||||
```bash
|
||||
sudo rabbitmqctl cluster_status
|
||||
```
|
||||
|
||||
**检查防火墙**（确保 `4369`、`25672`、`5672`、`15672` 端口开放）：
|
||||
|
||||
```bash
|
||||
sudo ufw allow 4369/tcp # Erlang 分布式通信端口
|
||||
sudo ufw allow 25672/tcp # RabbitMQ 集群通信端口
|
||||
sudo ufw allow 5672/tcp # AMQP 协议端口
|
||||
sudo ufw allow 15672/tcp # 管理界面端口
|
||||
sudo ufw reload
|
||||
```
|
||||
|
||||
**情况三 Cookie 不一致**
|
||||
|
||||
在所有节点执行：
|
||||
|
||||
```bash
|
||||
sudo cat /var/lib/rabbitmq/.erlang.cookie
|
||||
```
|
||||
|
||||
1. 停止 RabbitMQ：
|
||||
|
||||
```
|
||||
sudo systemctl stop rabbitmq-server
|
||||
```
|
||||
|
||||
2. 修改 Cookie（复制主节点的 Cookie 到其他节点）：
|
||||
|
||||
```
|
||||
echo "YOUR_MASTER_NODE_COOKIE" | sudo tee /var/lib/rabbitmq/.erlang.cookie
|
||||
```
|
||||
|
||||
3. 设置权限：
|
||||
|
||||
```
|
||||
sudo chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
|
||||
sudo chmod 400 /var/lib/rabbitmq/.erlang.cookie
|
||||
```
|
||||
|
||||
4. 重启 RabbitMQ：
|
||||
|
||||
```
|
||||
sudo systemctl start rabbitmq-server
|
||||
```
|
||||
|
||||
**情况四 管理界面用户权限问题**
|
||||
|
||||
如果用户没有 **跨节点访问权限**，管理界面可能无法获取其他节点的数据。
|
||||
|
||||
**解决方案**
|
||||
|
||||
确保用户在所有节点都有 **管理员权限**：
|
||||
|
||||
```
|
||||
sudo rabbitmqctl set_user_tags <username> administrator
|
||||
sudo rabbitmqctl set_permissions -p / <username> ".*" ".*" ".*"
|
||||
```
|
||||
|
||||
例如：
|
||||
|
||||
```
|
||||
sudo rabbitmqctl set_user_tags admin administrator
|
||||
sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
|
||||
```
|
||||
|
||||
**情况五 管理界面缓存问题**
|
||||
|
||||
浏览器可能缓存了旧数据，导致显示异常。
