将需要用到的资源上传到云服务器，主要包括RocketMQ软件包和JDK运行环境

1.基础配置

将文件上传到/opt目录下

# 解压rocketmq
mkdir rocketmq
mv rocketmq.zip ./rocketmq
cd rocketmq
unzip rocketmq.zip

# 解压jdk
tar -zxvf jdk-8u202-linux-x64.tar.gz
mv jdk-8u202-linux-x64 jdk8

进入rocketmq文件夹，修改conf目录下的broker.conf文件：

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
aclEnable=true
brokerIP1=IP地址
namesrvAddr=IP地址:9876

主要增加了以下几项：

• aclEnable=true ：开启权限控制
• brokerIP1=IP地址：brokerIP
• namesrvAddr=IP地址:9876：nameserver的IP

如果只是内网访问也可以不开启权限控制

如果开启了acl，文件配置：修改plain_acl.yml

globalWhiteRemoteAddresses:
- 192.168.2.131
- 192.168.2.132

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: 12345678
  secretKey: 12345678
  admin: true

注意accessKey和secretKey要大于6位

2.启动

需要启动nameserver和broker，进入rocketmq文件夹：

cd /opt/rocketmq

分别执行以下命令：

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

3.其他配置

上面rocketmq.zip是已经修改好内存配置信息的，也可以自定义broker 和nameserver的内存信息： 进入bin目录：

vim runserver.sh

修改jdk信息： 修改nameserver内存信息：

同样执行下面命令修改broker内存信息：

vim runbroker.sh

4.开机启动

cd /lib/systemd/system/

vim nameserver.service

[Unit]
Description=nameserver
After=network.target

[Service]
Environment="JAVA_HOME=/opt/jdk8"
Type=simple
#alone
ExecStart=sh /opt/rocketmq/bin/mqnamesrv &
ExecReload=sh /opt/rocketmq/bin/mqshutdown namesrv
ExecStop=sh /opt/rocketmq/bin/mqshutdown namesrv

[Install]
WantedBy=multi-user.target

vim broker.service

[Unit]
Description=broker
After=network.target

[Service]
