DockerCompose多应用布署

一、安装dockercompose

1、下载
1
curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
2、赋权
1
chmod +x /usr/local/bin/docker-compose
3、查看版本
1
docker-compose --version
4、卸载
1
rm docker-compose

二、配置docker-compose.yml

docker-compose 同目录创建 docker-compose.yml，也可以创建在其他目录，启动时使用-f参数指定文件路径

其中broker配置store的时候，宿主机/data/middleware/rocketmq/data/下的store需要赋权，使docker可以写数据，否则broker无法启动

三、配置broker.conf

三个broker都需要配置，注意brokerName各不相同

rokerClusterName = DefaultCluster
brokerName = rocketmq-broker-1
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
brokerIP1=192.168.1.170
storePathRootDir=/home/rocketmq/store

四、docker-compose常用命令

启动服务

1
2
3
# -f 指定配置文件 文件名是docker-compose.yml且与docker-compose同目录时可以不指定，直接docker-compose up -d 启动

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

重新启动指定服务

1
docker-compose up -d 【服务名】

重启全部服务

1
docker-compose restart

自动关闭并删除容器

1
docker-compose down

加参数 -v 同时删除卷

1
docker-compose down -v
