Rocketmq安裝（Linux）

1. 建立用戶

groupadd rocketmq #建立rocketmq用戶組
useradd -d /usr/rocketmq  -g rocketmq -m rocketmq #建立rocketmq用戶
passwd  rocketmq  #設置rocketmq密碼

2. 查看JAVA環境

[rocketmq@localhost ~]$ java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

3. 下載編譯

https://github.com/alibaba/RocketMQ （老版本，3.*.*）
https://github.com/apache/incubator-rocketmq（最新地址，Rocketmq已捐贈給Apache基金會）(4.*.* 開始)
mvn 安裝：https://my.oschina.net/u/1179666/blog/862778
#經過GIT下載最新的rocketmq,也能夠下載對應版本的rocketmq源碼
[root@localhost install]#  git clone https://github.com/apache/incubator-rocketmq.git

4. 下載(暫不使用，使用3的步驟)

[rocketmq@localhost install]$ wget https://github.com/alibaba/RocketMQ/archive/v3.5.8.zip
wget https://github.com/apache/incubator-rocketmq/archive/ROCKETMQ-62.zip
[rocketmq@localhost install]$ git clone https://github.com/apache/incubator-rocketmq/archive/release-4.0.0-incubating.zip

5. 修改環境變量

[root@b5eaa70483ff install]# echo 'export JAVA_HOME=/usr/java/jdk1.8.0_111' >> /etc/profile
#安裝maven
[root@b5eaa70483ff install]# unzip apache-maven-3.3.3.zip
[root@b5eaa70483ff install]# echo 'export M2_HOME=/usr/local/maven/apache-maven-3.3.3' >> /etc/profile
[root@b5eaa70483ff install]# echo 'export M2=$M2_HOME/bin' >> /etc/profile
[root@b5eaa70483ff install]# echo 'export MAVEN_OPTS="-Xms256m-Xmx512m"' >> /etc/profile
[root@b5eaa70483ff install]# echo 'export PATH=$M2:$PATH' >> /etc/profile

6. 編譯

[root@9a4ee3593c26 incubator-rocketmq]# mvn clean package install -Prelease-all assembly:assembly -U 
4.2.0前面命令編譯報錯：Could not find goal 'assembly' in plugin org.apache.maven.plugins:maven-assembly-plugin:3.0.0 among available goals help, single
4.2.0新編譯命令：mvn -Prelease-all -DskipTests clean install -U
#編譯，在target目錄下打包編譯後的項目爲tar.gz包
[root@localhost target]# ls
apache-rocketmq-all         archive-tmp           checkstyle-checker.xml  effective-pom
apache-rocketmq-all.tar.gz  checkstyle-cachefile  checkstyle-result.xml   maven-shared-archive-resources
拷貝項目到用戶rocketmq目錄下：
/usr/rocketmq/rocketmq/apache-rocketmq-all.tar.gz
[rocketmq@localhost bin]$ tar -zxvf apache-rocketmq-all.tar.gz

7. 啓動配置

[rocketmq@localhost bin]$ chmod +x mqadmin mqbroker mqfiltersrv mqshutdown  mqnamesrv
[rocketmq@localhost bin]$ ./mqnamesrv

The Name Server boot success. serializeType=JSON
[rocketmq@localhost bin]$ nohup ./mqnamesrv & #後臺啓動 Name Server
[rocketmq@localhost bin]$ nohup ./mqbroker -n localhost:9876 & #後臺啓動Broker
[rocketmq@localhost bin]$ nohup ./mqbroker -c /usr/rocketmq/rocketmq/conf/2m-2s-sync/broker-a.properties -n 127.0.0.1:9876  &#使用配置文件，設置本機IP,解決多網卡識別錯誤問題，可考慮在docker下錯誤問題（待測試）
[rocketmq@localhost 2m-2s-sync]$ more broker-a.propertie

[rocketmq@localhost bin]$ sh mqshutdown namesrv #關閉Name Server
