828华为云征文 | 云服务器Flexus X实例,Docker集成搭建搭建Flink
Apache Flink是一个分布式大数据计算引擎,专为处理无界和有界数据流上的有状态计算而设计,以其高吞吐量、低延迟和高性能在实时流处理和批量计算领域脱颖而出,Flink支持批流一体化,即能够同时处理实时数据流和静态数据集,使得数据处理更加灵活高效
华为云端口放行
- 服务器放行对应端口8082
Docker安装并配置镜像加速
1、购买华为云 Flexus X 实例
Flexus云服务器X实例-华为云 (huaweicloud.com)
2、docker安装
yum install -y docker-ce
3、验证 Docker 是否安装成功,启动docker服务并设置开机自启动,且查看docker状态
docker --version systemctl enable docker systemctl start docker systemctl status docker
4、docker-ce下载
wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.huaweicloud.com/docker-ce/linux/centos/docker-ce.repo
5、路径/etc/yum.repos.d修改配置文件
[docker-ce-stable] name=Docker CE Stable - $basearch baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/$basearch/stable enabled=1 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-stable-debuginfo] name=Docker CE Stable - Debuginfo $basearch baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/debug-$basearch/stable enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-stable-source] name=Docker CE Stable - Sources baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/source/stable enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-test] name=Docker CE Test - $basearch baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/$basearch/test enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-test-debuginfo] name=Docker CE Test - Debuginfo $basearch baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/debug-$basearch/test enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-test-source] name=Docker CE Test - Sources baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/source/test enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-nightly] name=Docker CE Nightly - $basearch baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/$basearch/nightly enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-nightly-debuginfo] name=Docker CE Nightly - Debuginfo $basearch baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/debug-$basearch/nightly enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg [docker-ce-nightly-source] name=Docker CE Nightly - Sources baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/9.9/source/nightly enabled=0 gpgcheck=1 gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg
6、清除和构建缓存
yum clean all yum makecache
7、docker配置镜像加速(在华为云镜像中心可获取自己的镜像加速配置)
8、创建镜像加速配置文件
vim /etc/docker/daemon.json
{ "registry-mirrors": [ "https://fd0cfec0ac0d446db7fd9d27e92d4a8e.mirror.swr.myhuaweicloud.com" ] }
9、重新加载配置文件,重新启动docker,查看是否配置成功
systemctl daemon-reload systemctl restart docker.service
10、docker info查看配置信息,是否配置成功镜像加速
docker info
搭建Flink
1、创建文件夹
mkdir /flink
2、编写docker-compose.yml文件
vim docker-compose.yml
version: "2.2" services: jobmanager: image: flink:1.14.4-scala_2.11 ports: - "8082:8082" command: jobmanager environment: - | FLINK_PROPERTIES= jobmanager.rpc.address: jobmanager taskmanager: image: flink:1.14.4-scala_2.11 depends_on: - jobmanager command: taskmanager scale: 1 environment: - | FLINK_PROPERTIES= jobmanager.rpc.address: jobmanager taskmanager.numberOfTaskSlots: 2
3、运行docker-compose.yml文件
docker-compose up -d
4、关闭服务器防火墙
systemctl stop firewalld systemctl status firewalld
5、浏览器地址访问公网IP:8082
总结
