下载rocketmq源码
https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.9.2/rocketmq-all-4.9.2-source-release.zip
maven下载
https://maven.apache.org/download.cgi
下载jdk1.8：https://www.oracle.com/java/technologies/downloads/#java8
https://download.oracle.com/otn/java/jdk/8u311-b11/4d5417147a92418ea8b615e228bb6935/jdk-8u311-linux-x64.tar.gz
jdk安装及环境变量配置
cd /usr/local
把下载好的jdk通过xftp放入到/usr/local下，通过解压"tar -zxvf jdk-8u311-linux-x64.tar.gz"
环境变量
export JAVA_HOME=/usr/local/jdk1.8.0_311
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
执行source /etc/profile，使环境变量生效,运行java命令，看jdk安装是否成功
maven安装及环境变量配置
cd /usr/local
把下载好的maven通过xftp放入到/usr/local/soft下，通过解压"tar zxvf apache-maven-3.8.4-bin.tar.gz"
vim /etc/profile文件，追加如下内容
#maven环境变量配置
export MAVEN_HOME=/usr/local/apache-maven-3.8.4
export PATH=$MAVEN_HOME/bin:$PATH
执行source /etc/profile，使环境变量生效，执行"mvn -v"，看maven安装是否成功
编译rocketmq源码
cd /usr/local
把下载好的源码包通过xftp放入到/usr/local/soft下，通过解压"unzip rocketmq-all-4.9.2-source-release.zip"
cd rocketmq-all-4.9.2
mvn -Prelease-all -DskipTests clean install -U
编译成功会有“building success”
编译好的文件在“/usr/local/rocketmq-all-4.9.2/distribution/target”目录下，有apache-rocketmq，有tar.gz,zip的编译好文件

vim /usr/local/rocketmq-all-4.9.2/distribution/target/rocketmq-4.9.2/rocketmq-4.9.2/bin/runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
增加环境变量
export ROCKET_HOME=/usr/local/rocketmq-all-4.9.2/distribution/target/rocketmq-4.9.2/rocketmq-4.9.2
export PATH=$ROCKETMQ_HOME/bin:$PATH
启动
cd /usr/local/rocketmq-all-4.9.2/distribution/target/rocketmq-4.9.2/rocketmq-4.9.2/bin
nohup sh mqnamesrv &
修改配置：
vim /usr/local/rocketmq-all-4.9.2/distribution/target/rocketmq-4.9.2/rocketmq-4.9.2/bin/runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms215m -Xmx1g"
启动broker服务：nohup sh mqbroker &
关闭namesrv服务：sh mqshutdown namesrv
关闭broker服务 ：sh mqshutdown broker
