在Linux上安裝Maven

下載Maven

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

添加阿里雲鏡像

修改maven/conf目錄下的settings.xml

在mirrors節點下添加

<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環境變量

修改/etc/profile

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

配置java環境變量

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

環境變量修完執行source /etc/profile立即生效

查看java安裝目錄

所有類安裝所在目錄

java -verbose

查看JAVA_HOME

echo $JAVA_HOME

Linux下使用Maven編譯Rocket源碼並安裝

Rocketmq4.6+需要jdk1.8環境編譯和運行

參考文章

下載源碼包

rocketmq-all-4.6.1-source-release.zip

解壓包並編譯源碼

unzip rocketmq-all-4.6.1-source-release.zip

移動文件到指定目錄/usr/local/下

mv rocketmq-all-4.6.1-source-release/ /usr/local/rocketmq-all-4.6.1/

切換到/usr/local/rocketmq-all-4.6.1/目錄下

cd /usr/local/rocketmq-all-4.6.1/

執行meaven編譯源碼命令

mvn -Prelease-all -DskipTests clean install -U

找到編譯後的文件

cd distribution/target/rocketmq-4.6.1/

移動編譯後的文件到指定目錄下

mv rocketmq-4.6.1/ /usr/local/rocketmq-4.6.1/

切換到/usr/local/rocketmq-4.6.1/bin/目錄下

cd /usr/local/rocketmq-4.6.1/bin/

創建日誌文件夾

mkdir /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/

Start Name Server（註冊中心）

nohup sh ./mqnamesrv > /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/namesrv.log &

查看日誌

tail -f /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/namesrv.log
# 啓動成功標誌
# The Name Server boot success. serializeType=JSON

Start Broker（具體服務）

nohup sh ./mqbroker -n localhost:9876 > /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/mqbroker.log &

# 執行出錯
# Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error='Cannot # # allocate memory' (errno=12)
# 可以看出是分配的內存不夠用

原來，執行./mqbroker其實是執行./runserver.sh和./runbroker.sh

查看./runserver.sh和./runbroker.sh啓動時分配的內存

# runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

# runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"

發現 runbroker.sh 分配的內存過大

修改啓動時分配的內存

# runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn128m"

重新啓動./mqbroker

查看日誌

tail -f /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/mqbroker.log
# 啓動成功標誌
# The broker[dandanRoot, 192.168.1.113:10911] boot success. serializeType=JSON

發現執行成功

可能出現的另一個錯誤

找不到 host name，此時需要在 /etc/hosts 中配置對應的host

Send & Receive Messages（測試）

在/tools.sh中添加配置

export NAMESRV_ADDR=localhost:9876

執行測試腳本

sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
# 出現錯誤
# org.apache.rocketmq.client.exception.MQClientException: No route info of this topic: TopicTest
# 啓動./mqbroker時要帶上參數 -n localhost:9876,不然連不到註冊中心 namesrv
# 重新啓動
# nohup sh ./mqbroker -n localhost:9876 > /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/mqbroker.log &
# 發送消息成功
# SendResult [sendStatus=SEND_OK, msgId=C0A8017C00006BC7C0546460AEE203E7, offsetMsgId=C0A8017100002A9F00000000000317BF, messageQueue=MessageQueue [topic=TopicTest, brokerName=dandanRoot, queueId=2], queueOffset=249]


sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
# 接收消息成功

編譯

進入rocketmq-console目錄

執行編譯

mvn clean package -Dmaven.test.skip=true

啓動

編譯成功後在rocketmq-console/target目錄下執行rocketmq-console-ng-1.0.1.jar

啓動時，直接動態添加nameserver地址或編輯application.properties添加屬性

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

啓動成功後訪問服務器8080端口即可
添加--rocketmq.config.namesrvAddr=127.0.0.1:9876命令的替代方案，在console的頁面中，在opt的NameSvrAddrList中添加192.168.1.113:9876，按enter鍵，按UPDATE按鈕即可

安裝啓動常見錯誤

編譯時包無法在mirror上找到提示502錯誤

原因：網絡不好或maven倉庫服務器出錯

重試即可，或者歡迎鏡像倉庫

發送失敗提示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在哪兒

在tools腳本中添加

export NAMESRV_ADDR=localhost:9876

啓動broker失敗 Cannot allocate memory

原因：jvm啓動初始化內存分配大於物理內存

[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

修改啓動腳本中的jvm參數

runbroker.sh broker

runserver.sh nameserver

默認數值給的都很大，改小即可

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

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