## 1、Please set the JAVA\_HOME variable in your environment, We need java(x64) ##

解决：

本地需要配置 JAVA_HOME 使用命令 vim ~/.bash_profile
    JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home"
    export JAVA_HOME
    CLASS_PATH="$JAVA_HOME/lib"
    PATH=".$PATH:$JAVA_HOME/bin"

## 2、maven编译失败报错 ##

[ERROR] Failed to execute goal on project rocketmq-console-ng:
    Could not resolve dependencies for project org.apache:rocketmq-console-ng:jar:1.0.0: 
    The following artifacts could not be resolved: org.apache.rocketmq:rocketmq-tools:jar:4.4.0-SNAPSHOT, org.apache.rocketmq:rocketmq-namesrv:jar:4.4.0-SNAPSHOT, 
    org.apache.rocketmq:rocketmq-broker:jar:4.4.0-SNAPSHOT:
    Could not find artifact org.apache.rocketmq:rocketmq-tools:jar:4.4.0-SNAPSHOT -> [Help 1]
    [ERROR]
    [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
    [ERROR] Re-run Maven using the -X switch to enable full debug logging.

解决：

<rocketmq.version>4.4.0-SNAPSHOT</rocketmq.version>  改为：  <rocketmq.version>4.4.0</rocketmq.version>

## 3、无法连接获取broker信息 ##

解决：

修改配置文件,名称路由地址为 namesrvAddr，例如我本机地址为
    src/main/resources/application.properties
    rocketmq.config.namesrvAddr=127.0.0.1:9876

## 4、连接不成功 ##

解决：

在阿里云，腾讯云或者虚拟机，记得检查端口号和防火墙是否启动
    阿里云控制台有安全组，需要开放对应的端口

## 5、maybe your broker machine memory too small ##

解决：

磁盘空间不够

## 6、NameServer内存或者Broker内存不够怎么处理 ##

[root@iZwz94sw188z3yfl7lpmmsZ apache-rocketmq]# sh bin/mqnamesrv
    Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
    Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future release.
    Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006ec800000, 2147483648, 0) failed; error='Cannot allocate memory' (errno=12)
    #
    # There is insufficient memory for the Java Runtime Environment to continue.
    # Native memory allocation (mmap) failed to map 2147483648 bytes for committing reserved memory.
    # An error report file with more information is saved as:
    # /usr/local/software/rocketmq-all-4.4.0/distribution/target/apache-rocketmq/hs_err_pid8993.log

解决：

找到 runserver.sh 修改 JAVA_OPT
    JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
    找到 runbroker.sh 修改 JAVA_OPT
    JAVA_OPT="${JAVA_OPT} -server -Xms528m -Xmx528m -Xmn256m"

## 7、org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException: sendDefaultImpl call timeout ##

解决：

原因：阿里云存在多网卡，rocketmq都会根据当前网卡选择一个IP使用，
    当你的机器有多块网卡时，很有可能会有问题。
    比如，我遇到的问题是我机器上有两个IP，一个公网IP，一个私网IP, 
    因此需要配置broker.conf 指定当前的公网ip, 然后重新启动broker

新增配置：conf/broker.conf  (属性名称brokerIP1=broker所在的公网ip地址 )
    新增这个配置：brokerIP1=120.76.62.137
    启动命令：nohup sh bin/mqbroker -n localhost:9876  -c ./conf/broker.conf &

## 8、MQClientException: No route info of this topic, TopicTest1 ##

解决：

原因：Broker 禁止自动创建 Topic，且用户没有通过手工方式创建 此Topic, 或者broker和Nameserver网络不通

通过 sh bin/mqbroker -m  查看配置
    autoCreateTopicEnable=true 则自动创建topic
    Centos7关闭防火墙  systemctl stop firewalld

## 9、控制台查看不了数据，提示连接 10909错误 ##

解决：

原因：Rocket默认开启了VIP通道，VIP通道端口为10911-2=10909

阿里云安全组需要增加一个端口 10909
