linux安装RocketMQ实例步骤

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

cd /usr/local/rocketmq/bin

启动：nohup sh mqnamesrv &

jps查看JDK进程是否有NamesrvStartup

2.13 启动BrokerServer

cd /usr/local/rocketmq/bin

master01启动：nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-a.properties >/dev/null 2>&1 &

master02启动：nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-b.properties >/dev/null 2>&1 &

jps查看JDK进程是否有BrokerStartup

3.通过console控制台监控rocketmq状态

3.1 将Tomcat压缩包上传到虚拟机进行解压  /usr/local  tar -zxvf xxxx解压

3.2 将rocketmq-web-console.war上传到Tomcat解压目录的webapps下

3.3 启动Tomcat

切换到/usr/local/apache-tomcat-7.0.65/bin

./startup.sh 启动   ./shutdown.sh 停止

3.4 修改解压后的rocketmq-web-console

/usr/local/apache-tomcat-7.0.65/webapps/rocketmq-web-console/WEB-INF/classes/config.properties配置文件

配置：

rocketmq.namesrv.addr=192.168.42.22:9876;192.168.42.33:9876

throwDone=true

3.5 两台机器防火墙关闭

systemctl stop firewalld.service

systemctl disable firewalld.service

配置完成后网页访问控制台,效果如下
