1.1 介绍
在使用 FlinkSpark 时发现从编程模型, 启动配置到运维管理都有很多可以抽象共用的地方, 目前streampark提供了一个flink一站式的流处理作业开发管理平台, 从流处理作业开发到上线全生命周期都做了支持, 是一个一站式的流出来计算平台。 未来spark开发也在规划范围内目前还不支持
1.2 下载
StreamPark安装包下载https://streampark.apache.org/download StreamPark官网https://streampark.apache.org/docs/intro 最新版为2.1.2本次安装为2.1.2版本
1.3 已有组件及版本

2.挂载与权限
2.1 k8s挂载
找运维开通权限主要是kubectl的权限 下载kubectl 权限文件/root/.kube/config 2.2 nfs挂载
找运维要服务ip
#挂载前请确保系统中已经安装了nfs-utils或nfs-common
sudo yum install nfs-utils
#创建待挂载目标目录
mkdir 待挂载目标目录 mkdir /localfolder/
#挂载文件系统
#挂载 CFS 根目录
#以下命令可以到 CFS 控制台-文件系统详情-挂载点详情中获取由于部分旧版本文件系统不支持 noresvport 参数具体挂载命令请以控制台建议命令为主。配置 norevsport 参数后在网络重连时使用新的 TCP 端口可以保障在网络异常到恢复期间、客户端和文件系统的连接不会中断建议启用该参数。
#另部分旧版本 Linux 内核需要使用 vers4 挂载若使用 vers4.0 挂载有异常可以尝试修改为 vers4。
sudo mount -t nfs -o vers4.0,noresvport 挂载点 IP:/ 待挂载目录
sudo mount -t nfs -o vers4.0,noresvport 10.0.24.4:/ /localfolder
#挂载 CFS 子目录
#以下命令可以到 CFS 控制台-文件系统详情-挂载点详情中获取由于部分旧版本文件系统不支持 noresvport 参数具体挂载命令请以控制台建议命令为主。配置 norevsport 参数后在网络重连时使用新的 TCP 端口可以保障在网络异常到恢复期间、客户端和文件系统的连接不会中断建议启用该参数。
#另部分旧版本 Linux 内核需要使用 vers4 挂载若使用 vers4.0 挂载有异常可以尝试修改为 vers4。
sudo mount -t nfs -o vers4.0,noresvport 10.0.24.4:/subfolder /localfolder 腾讯nfs(CFS)使用文档https://cloud.tencent.com/document/product/582/11523
2.3 Harbor
需要找运维开通权限 此处注意项目库要公开才可以使用 3.测试Flink
在k8s为flink单独开通命名空间并创建相应账户
kubectl create clusterrolebinding flink-role-bind --clusterroleedit --serviceaccountflink:flink在有k8s操作权限的节点运行flink-session
bin/flink run \
