1.安装JDK

1.1 检查当前虚拟机环境有没有JDK rpm -qa|grep java

1.2 卸载 rpm -e --nodeps xxxxxx(自己的openjdk)

1.3 安装JDK

在/usr/local新建一个java文件夹，然后将tar包上传到文件夹下

切换到/usr/local/java 使用tar -zxvf xxx解压

配置/etc/profile文件，加入JDK环境变量

export JAVA_HOME=/usr/local/java/jdk1.8.0_121 替换自己路径

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export PATH=$JAVA_HOME/bin:$PATH

应用文件 source /etc/profile

使用java -version查看版本

2.安装RocketMQ

2.1 配置/etc/hosts文件,网址写俩台主机的ip

192.168.42.22 rocketmq-nameserver1
192.168.42.22 rocketmq-master1
192.168.42.33 rocketmq-nameserver2
192.168.42.33 rocketmq-master2

2.2 重启网卡 service network restart

2.3 上传rocketmq压缩包，上传到/usr/local下

2.4 切换到/usr/local下解压rocketmq压缩包 tar -zxvf xxxxxx

2.5 更改解压文件夹名称

mv alibaba-rocketmq alibaba-rocketmq-3.2.6

2.6 创建软连接

ln -s alibaba-rocketmq-3.2.6 rocketmq

2.7 mkdir /usr/local/rocketmq/store

mkdir /usr/local/rocketmq/store/commitlog

mkdir /usr/local/rocketmq/store/consumequeue

mkdir /usr/local/rocketmq/store/index

2.8 把borker-a.properties 和borker-b.properties 上传到/usr/local/recketmq/conf/2m-noslave

2.9 master01配置borker-a.properties

brokerName=broker-a 对应文件名称

namesrvAddr=rocketmq-nameserver1:9876;rocketmq-nameserver2:9876

master02配置borker-b.properties

brokerName=broker-b 对应文件名称

namesrvAddr=rocketmq-nameserver1:9876;rocketmq-nameserver2:9876

2.10 修改日志

mkdir -p /usr/local/rocketmq/logs

cd /usr/local/rocketmq/conf && sed -i 's#${user.home}#/usr/local/rocketmq#g' *.xml

2.11 配置JVM参数,根据自己虚拟机实际大小修改

vi /usr/local/rocketmq/bin/runbroker.sh

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m"

vi /usr/local/rocketmq/bin/runserver.sh

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m"

2.12 启动NameServer
