RocketMq安装与启动
官方网站
GitHub
https://github.com/apache/rocketmq
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
查看java安装目录
所有类安装所在目录
java -verbose
查看JAVA_HOME
echo $JAVA_HOME
Linux下使用Maven编译Rocket源码并安装
Rocketmq4.6+需要jdk1.8环境编译和运行
下载源码包
rocketmq-all-4.6.1-source-release.zip
解压包并编译源码
unzip rocketmq-all-4.6.1-source-release.zip
移动文件到指定目录/usr/local/下
mv rocketmq-all-4.6.1-source-release/ /usr/local/rocketmq-all-4.6.1/
切换到/usr/local/rocketmq-all-4.6.1/目录下
cd /usr/local/rocketmq-all-4.6.1/
执行meaven编译源码命令
mvn -Prelease-all -DskipTests clean install -U
找到编译后的文件
cd distribution/target/rocketmq-4.6.1/
移动编译后的文件到指定目录下
mv rocketmq-4.6.1/ /usr/local/rocketmq-4.6.1/
切换到/usr/local/rocketmq-4.6.1/bin/目录下
cd /usr/local/rocketmq-4.6.1/bin/
创建日志文件夹
mkdir /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/
Start Name Server（注册中心）
nohup sh ./mqnamesrv > /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/namesrv.log &
查看日志
tail -f /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/namesrv.log
# 启动成功标志
# The Name Server boot success. serializeType=JSON
Start Broker（具体服务）
# -n localhost:9876指定对应的namesrv
nohup sh ./mqbroker -n localhost:9876 > /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/mqbroker.log &
# 执行出错
# Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error='Cannot # # allocate memory' (errno=12)
# 可以看出是分配的内存不够用
原来，执行./mqbroker其实是执行./runbroker.sh
查看./runserver.sh和./runbroker.sh启动时分配的内存
# runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
# runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
发现 runbroker.sh 分配的内存过大
修改启动时分配的内存
# runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn128m"
重新启动./mqbroker
查看日志
tail -f /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/mqbroker.log
# 启动成功标志
# The broker[dandanRoot, 192.168.1.113:10911] boot success. serializeType=JSON
发现执行成功
可能出现的另一个错误
找不到 host name，此时需要在 /etc/hosts 中配置对应的host
Send & Receive Messages（测试）
在/tools.sh中添加配置
export NAMESRV_ADDR=localhost:9876
执行测试脚本
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
# 出现错误
# org.apache.rocketmq.client.exception.MQClientException: No route info of this topic: TopicTest
# 启动./mqbroker时要带上参数 -n localhost:9876,不然连不到注册中心 namesrv
# 重新启动
# nohup sh ./mqbroker -n localhost:9876 > /usr/local/rocketmq-4.6.1/mylog/rocketmqlogs/mqbroker.log &
# 发送消息成功
# 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

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
添加--rocketmq.config.namesrvAddr=127.0.0.1:9876命令的替代方案，在console的页面中，在opt的NameSvrAddrList中添加192.168.1.113:9876，按enter键，按UPDATE按钮即可

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

RocketMQLog:WARN Please initialize the logger system properly.
java.lang.IllegalStateException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to

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

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
