RocketMQ安装与应用

1. 前提
   安装jdk1.8+

2. 安装

cd /home
wget http://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/4.6.0/rocketmq-all-4.6.0-source-release.zip
unzip rocketmq-all-4.6.0-source-release.zip
mv rocketmq-all-4.6.0-source-release rocketmq-all-4.6.0
cd rocketmq-all-4.6.0/
mvn -Prelease-all -DskipTests clean install -U
cd /home/rocketmq-all-4.6.0/distribution/target/rocketmq-4.6.0/rocketmq-4.6.0

3. 启动

nohup sh bin/mqnamesrv -c conf/broker.conf &
nohup sh bin/mqbroker -c conf/broker.conf autoCreateTopicEnable=true &

4. 停止

sh bin/mqshutdown broker
sh bin/mqshutdown namesrv

5. 配置

# cat conf/broker.conf
# 配置如下
brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
brokerIP1 = 39.108.249.168
namesrvAddr=39.108.249.168:9876
autoCreateTopicEnable=true
aclEnable=true
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

# cat conf/plain_acl.yml
# 配置如下
globalWhiteRemoteAddresses:
- 10.10.103.*
- 192.168.0.*
- 113.110.233.*

accounts:
- accessKey: RocketMQ
  secretKey: 12345678
  whiteRemoteAddress:
  admin: false
  defaultTopicPerm: DENY
  defaultGroupPerm: SUB
  topicPerms:
  - topicA=DENY
  - topicB=PUB|SUB
  - topicC=SUB
  groupPerms:
  # the group should convert to retry topic
  - groupA=DENY
  - groupB=PUB|SUB
  - groupC=SUB

- accessKey: rocketmq2
  secretKey: 12345678
  whiteRemoteAddress: 192.168.1.*
  # if it is admin, it could access all resources
  admin: true
