https://github.com/alibaba/RocketMQ/releases/download/v3.2.6/alibaba-rocketmq-3.2.6.tar.gz
解压
tar -xvf alibaba-rocketmq-3.2.6.tar.gz
需要jdk1.6以上
设置环境变量
vi .bash_profile
export JAVA_HOME=/opt/jdk6
export JRE_HOME=/opt/jdk6/jre
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:CLASSPATH
export ROCKETMQ_HOME=/opt/mq/alibaba-rocketmq
export NAMESRV_ADDR=127.0.0.1:9876
启动
cd alibaba-rocketmq/bin
./play.sh
启动完成后
jps
会有NamesrvStartup和BrokerStartup两个java进程
如果没有问题，停止服务
cd alibaba-rocketmq/bin
sh mqshutdown broker
sh mqshutdown namesrv
二.设置防火墙：
默认启动用会使用3个端口 9876,10911,10912
分别代表名称服务端口，broker端口，broker ha端口。
ha端口haListenPort表示Master监听Slave请求的端口，默认为服务端口+1
添加到/etc/sysconfig/iptables的filter表INPUT链中
-A INPUT -m state --state NEW -m tcp -p tcp --dport 9876 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10911 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10912 -j ACCEPT
添加完成后重启防火墙
service iptables restart
四.获取broker默认配置
cd alibaba-rocketmq/bin
sh mqbroker -m
启动时如何加载配置文件呢
1.生成默认的配置模板
sh mqbroker -m > broker.p
2.修改配置
注意以下两个参数
storePathRootDir=/opt/mq/rocketmq/store
storePathCommitLog=/opt/mq/rocketmq/store/commitlog
默认commitlog是存放在用户主目录的下的store/commitlog目录下
namesrvAddr=127.0.0.1:9876
名称服务器地址，可以在命令行通过-n传入，多个名称服务器用;隔开
brokerIP1=192.168.6.57
根据实际情况填写，默认启动时自动识别,一般用于多网卡识别错误，手工配置。
brokerName=peteccBrkMaster
broker名称，默认主机名，我们可以改下peteccBrkMaster
listenPort=10911
默认监听端口
brokerId=0
0表示master,>0表示slave
autoCreateTopicEnable=true
是否自动创建topic,线上环境建议关闭
deleteWhen=04
删除文件的时间点，默认凌晨4点
fileReservdTime=48
文件保留时间，默认48小时
3.加载配置
nohup sh mqbroker -c broker.p &
五.生成namesrv默认配置
sh mqnamesrv -p >namesrv.p
可以通过 sh mqnamesrv -h 查看命令参数。
启动命令
nohup sh mqnamesrv -c namesrv.p &
六操作系统配置
os.sh大概意思是根据rocketmq的特点，修改系统参数，修改磁盘调度算法。
接下来我们操作一下，这个如要root权限
vim /etc/sysctl.conf增加
vm.overcommit_memory=1
vm.min_free_kbytes=5000000
vm.drop_caches=1
vm.zone_reclaim_mode=0
vm.max_map_count=655360
vm.dirty_background_ratio=50
vm.dirty_ratio=50
vm.page-cluster=3
vm.dirty_writeback_centisecs=360000
vm.swappiness=10
修改完成后sysctl -p
修改最大打开文件描述数
vim /etc/security/limits.conf添加
* soft nofile 655350
* hard nofile 655350
退出当前用户重新login就会生效,使用ulimit -n验证下。
修改io调试算法为deadline
查看当前系统支持的IO调度算法
[rocketmq@vtfsdb3 bin]$ dmesg | grep -i scheduler
查看当前系统默认io调度算法
[rocketmq@vtfsdb3 bin]$ cat /sys/block/sda/queue/scheduler
noop anticipatory deadline [cfq]
注意中间的sda换成实际运行存储rocketmq的磁盘，这个自己通过fdisk,df自己找出来吧，
临时更改I/O调度方法:
echo 'deadline' > /sys/block/sda/queue/scheduler
将这句加入开机启动/etc/rc.local中吧
修改完成，确认下
cat /sys/block/sda/queue/scheduler
jvm参数调整
cd alibaba-rocketmq/bin
有两个文件runserver.sh和runbroker.sh两个shell脚本，分别是name server和broker server的配置启动脚本
#vim修改runbroker.sh、runserver.sh两个文件

七. mqadmin 命令使用：
cd /opt/mq/alibaba-rocketmq/bin
1. 查看所有消费组group:
sh mqadmin consumerProgress -n 192.168.6.57:9876
2. 查看指定消费组下的所有topic数据堆积情况：
sh mqadmin consumerProgress -n 192.168.6.57:9876 -g benchmark_consumer_33
3. 查看所有topic :
sh mqadmin topicList -n 192.168.6.57:9876
4. 查看topic信息列表详情统计
sh mqadmin topicstatus -n 192.168.6.57:9876 -t myTopicTest1
5. 新增topic
sh mqadmin updateTopic –n 192.168.6.57 –c groupname –t topicname
6. 删除topic
sh mqadmin deleteTopic –n 192.168.6.57:9876 –c groupname –t topicname
