故障處理與恢復

常見故障處理腳本

#!/bin/bash
# 消息隊列故障診斷工具

check_kafka_health() {
    echo "=== Kafka健康檢查 ==="
    
    # 檢查Broker狀態
    for broker in "${KAFKA_BROKERS[@]}"; do
        if nc -z $broker 9092; then
            echo "✅ Broker $broker: 正常"
        else
            echo "❌ Broker $broker: 異常"
        fi
    done

    # 檢查ZooKeeper連接
    echo "檢查ZooKeeper狀態..."
    kafka-topics.sh --list --bootstrap-server ${KAFKA_BROKERS[0]} > /dev/null 2>&1
    if [ $? -eq 0 ]; then
        echo "✅ ZooKeeper連接: 正常"
    else
        echo "❌ ZooKeeper連接: 異常"
    fi

    # 檢查分區狀態
    echo "檢查分區狀態..."
    kafka-topics.sh --describe --under-replicated-partitions --bootstrap-server ${KAFKA_BROKERS[0]}
}

check_rabbitmq_health() {
    echo "=== RabbitMQ健康檢查 ==="
    
    # 檢查節點狀態
    for node in "${RABBITMQ_NODES[@]}"; do
        status=$(ssh $node "rabbitmqctl node_health_check" 2>/dev/null)
        if [ $? -eq 0 ]; then

        fi
    done

    # 檢查隊列狀態
    echo "檢查隊列狀態..."
    ssh ${RABBITMQ_NODES[0]} "rabbitmqctl list_queues name messages messages_ready messages_unacknowledged"
}

# 自動修復函數
auto_recover() {
    case $1 in
        "kafka")
            echo "嘗試重啓Kafka Broker..."
            for broker in "${KAFKA_BROKERS[@]}"; do
                ssh $broker "systemctl restart kafka-server"
            done

        *)
            echo "未知的消息隊列類型"
            ;;
    esac
}

數據恢復策略

#!/bin/bash
# 消息隊列數據恢復腳本

recover_kafka_data() {
    # 1. 停止所有Broker
    for broker in "${KAFKA_BROKERS[@]}"; do
        ssh $broker "systemctl stop kafka-server"
    done

    # 2. 從備份恢復數據
    BACKUP_DIR="/backup/kafka/$(date +%Y%m%d)"
    for broker in "${KAFKA_BROKERS[@]}"; do
        rsync -av $BACKUP_DIR/$broker/ $broker:/data/kafka/
    done

    # 3. 重新啓動集羣
    for broker in "${KAFKA_BROKERS[@]}"; do
        ssh $broker "systemctl start kafka-server"
    done

    # 4. 驗證數據完整性
    kafka-topics.sh --describe --bootstrap-server ${KAFKA_BROKERS[0]}
}

recover_rabbitmq_data() {
    # 1. 停止集羣
    for node in "${RABBITMQ_NODES[@]}"; do
        ssh $node "systemctl stop rabbitmq-server"
    done

    # 2. 恢復數據文件
    BACKUP_DIR="/backup/rabbitmq/$(date +%Y%m%d)"
    for node in "${RABBITMQ_NODES[@]}"; do
        rsync -av $BACKUP_DIR/$node/ $node:/var/lib/rabbitmq/
    done

    # 3. 重新組建集羣
    ssh ${RABBITMQ_NODES[0]} "systemctl start rabbitmq-server"
    for i in "${!RABBITMQ_NODES[@]}"; do
        if [ $i -ne 0 ]; then
            ssh ${RABBITMQ_NODES[$i]} "systemctl start rabbitmq-server"
            ssh ${RABBITMQ_NODES[$i]} "rabbitmqctl join_cluster rabbit@${RABBITMQ_NODES[0]}"
        fi
    done

    # 4. 同步鏡像隊列
    ssh ${RABBITMQ_NODES[0]} "rabbitmqctl sync_queue all"
}

安全加固方案

TLS/SSL加密配置

# Kafka SSL配置
#!/bin/bash
# 生成SSL證書
keytool -keystore kafka.server.keystore.jks -alias localhost -validity 365 -genkey
openssl req -new -x509 -keyout ca-key -out ca-cert -days 365

# 配置SSL
cat >> server.properties << EOF
listeners=SSL://:9093
ssl.keystore.location=/path/to/kafka.server.keystore.jks
ssl.keystore.password=keystore_password
ssl.key.password=key_password
ssl.truststore.location=/path/to/kafka.server.truststore.jks
ssl.truststore.password=truststore_password
ssl.client.auth=required
EOF

# RabbitMQ SSL配置
cat >> rabbitmq.conf << EOF
listeners.ssl.default = 5671
ssl_options.cacertfile = /path/to/ca_certificate.pem
ssl_options.certfile = /path/to/server_certificate.pem
ssl_options.keyfile = /path/to/server_key.pem
ssl_options.verify = verify_peer
ssl_options.fail_if_no_peer_cert = true
EOF

訪問控制配置

# Kafka ACL配置
kafka-acls.sh --bootstrap-server localhost:9092 \
    --add \
    --allow-principal User:producer \
    --operation Write \
    --topic test-topic

kafka-acls.sh --bootstrap-server localhost:9092 \
    --add \
    --allow-principal User:consumer \
    --operation Read \
    --topic test-topic

# RabbitMQ權限控制
rabbitmqctl set_permissions -p / producer ".*" ".*" ".*"
rabbitmqctl set_permissions -p / consumer "" ".*" ".*"

總結與最佳實踐

運維檢查清單

• [ ] 集羣節點數量符合高可用要求
• [ ] 監控告警體系完備並經過測試
• [ ] 備份策略制定並定期驗證恢復
• [ ] 安全配置（SSL、ACL）已啓用
• [ ] 性能參數根據業務需求優化
• [ ] 故障恢復流程文檔化

版本升級策略

消息隊列	升級方式	注意事項
Kafka	滾動升級	確保版本兼容性，先升級ZK
RabbitMQ	逐個節點升級	保持erlang cookie一致
RocketMQ	主從切換升級	確保NameServer版本兼容

通過合理的集羣部署、完善的監控體系、定期的維護演練，可以確保消息隊列集羣在生產環境中的穩定運行，為業務系統提供可靠的消息通信保障。
