#### 1.从GitHub上下载源码并上传到服务器 ####

![\[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-ZDdGCpdU-1603030341885)(image-rocketMQ/image-20200218134855528.png)\]][img-ZDdGCpdU-1603030341885_image-rocketMQ_image-20200218134855528.png]

#### 2.在Linux上安装Maven ####

**下载Maven**

wget https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

**添加阿里云镜像**

修改`maven/conf`目录下的`settings.xml`

在`mirrors`节点下添加

<mirror> 
        <id>aliyun-maven</id> 
        <mirrorOf>*</mirrorOf> 
        <name>aliyun maven</name> 
        <url>http://maven.aliyun.com/nexus/content/groups/public</url> 
    </mirror>

**配置maven环境变量**

修改`/etc/profile`

export M2_HOME=/usr/local/maven
    export PATH=$PATH:$M2_HOME/bin

**配置java环境变量**

export JAVA_HOME="/usr/java/jdk1.8.0_181-amd64"
    export CLASS_PATH="$JAVA_HOME/lib"
    export PATH=".$PATH:$JAVA_HOME/bin"

环境变量修完执行`source /etc/profile`立即生效

**进入rocketmq主目录编译项目**

mvn -Prelease-all -DskipTests clean install -U

#### 3.启动nameserver ####

`bin`目录下执行

./mqnamesrv

正常提示

![在这里插入图片描述][20201018221351788.png_pic_center]

#### 4.启动Broker ####

./mqbroker -n localhost:9876

正常提示

![在这里插入图片描述][20201018221406972.png_pic_center]

#### 5.测试消息发送 ####

使用`tool.sh`脚本执行测试程序

在`bin`目录下执行

./tools.sh org.apache.rocketmq.example.quickstart.Producer

提示如下表示成功

**6.接受消息**

./tools.sh org.apache.rocketmq.example.quickstart.Consumer

### 控制台rocketmq-console编译安装 ###

#### 下载 ####

https://github.com/apache/rocketmq-externals

**中文指南**

https://github.com/apache/rocketmq-externals/blob/master/rocketmq-console/doc/1\_0\_0/UserGuide\_CN.md

#### 上传到服务器并解压缩 ####

#### 编译 ####

进入`rocketmq-console`目录

执行编译

mvn clean package -Dmaven.test.skip=true

#### 启动 ####

编译成功后在`rocketmq-console/target`目录下执行`rocketmq-console-ng-1.0.1.jar`

启动时，直接动态添加`nameserver`地址或编辑`application.properties`添加属性

java -jar rocketmq-console-ng-1.0.1.jar --rocketmq.config.namesrvAddr=127.0.0.1:9876

启动成功后访问服务器8080端口即可

#### pom.xml依赖 ####

<dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-client</artifactId>
            <version>4.6.1</version>
     </dependency>

### 安装启动常见错误 ###

#### 编译时包无法在mirror上找到 提示502错误 ####

\*\*原因：\*\*网络不好或maven仓库服务器出错

重试即可，或者欢迎镜像仓库

#### **发送失败提示connect to null failed** ####

./tools.sh org.apache.rocketmq.example.quickstart.Producer
    22:49:02.470 [main] DEBUG i.n.u.i.l.InternalLoggerFactory - Using SLF4J as the default logging framework
    RocketMQLog:WARN No appenders could be found for logger (io.netty.util.internal.PlatformDependent0).
    RocketMQLog:WARN Please initialize the logger system properly.
    java.lang.IllegalStateException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to
     null failed

\*\*原因：\*\*不知道`nameserver`在哪儿

在`tools`脚本中添加

export NAMESRV_ADDR=localhost:9876

#### 启动broker失败 Cannot allocate memory ####

\*\*原因：\*\*jvm启动初始化内存分配大于物理内存

[root@node-113b bin]# ./mqbroker -n localhost:9876
    Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 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 8589934592 bytes for committing reserved memory.
    # An error report file with more information is saved as:
    # /usr/local/rocketmq/bin/hs_err_pid1997.log

修改启动脚本中的jvm参数

`runbroker.sh` broker

`runserver.sh` nameserver

默认数值给的都很大，改小即可

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=100m"

#### 启动broker成功但提示：Failed to obtain the host name ####

[root@node-113b bin]# ./mqbroker -n localhost:9876

hosts里添加映射即可
