公司要上GPS資料平臺，中介軟體領導決策用rocketmq叢集，以前都是用的rabbitmq，據說rocketmq效能更加好，所以進行搭建學習

伺服器環境：centos7 ,連上阿里映象源

安裝使用者：root，關閉防火牆

1.安裝docker

yum -y install docker //安裝docker

systemctl start docker //啟動docker

systemctl status docker//檢視狀態

systemctl enable docker.service //開機自啟

其他docker 基本命令

docker pull xxx

docker run xxx

docker ps -a

docker start xxx

docker stop xxx

docker restart xxx

docker rm  xxx

2安裝docker Compose

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose //新增許可權

docker-compose --version //檢視版本

3.安裝dokcker管理面板portainer 漢化版本

docker pull portainer/portainer-ce

wget https://imnks.com/usr/uploads/2021/11/portainer-ce-2.9.2-public-cn-1101.zip
unzip portainer-ce-2.9.2-public-cn-1101.zip

docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data -v /root/public:/public portainer/portainer-ce

瀏覽器輸入IP:9000

 如果無法進入管理面板，提示許可權不足，進行如下設定

修改/etc/selinux/config 檔案

將SELINUX=enforcing改為SELINUX=disabled

4.安裝rocketmq叢集和管理工具

建立指令碼：vi rocketmq.yml

指令碼如下-----------------------------------

建立資料夾

mkdir -p /usr/local/bin/atp/rocketmq/conf/broker1

mkdir -p /usr/local/bin/atp/rocketmq/conf/broker2

mkdir -p /usr/local/bin/atp/rocketmq/conf/broker3

vi  /usr/local/bin/atp/rocketmq/conf/broker3/broker.conf

建立broker.conf

brokerClusterName = DefaultCluster
#broker名稱
brokerName = rocketmq-broker-1
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

啟動叢集：

docker-compose -f rocketmq.yml -p rocketmq up -d
