Flink On Local
环境准备
准备一台2核4G以上配置的Linux机器节点(CentOs、macOS等)
Java SE Development Kit 8及以上版本安装确保本机节点hostname对应的ip正确
因为进程启动时候会去拿本机的ip地址,所以要保证
/etc/hosts文件中hostname 对应ip地址正确hostname
# 得到上面显示的结果，例如：baisui-host-1
ping baisui-host-1
# 确认ip节点是否为本机ip无误,如不正确，请在/etc/hosts将正确的hostname与ip映射关系加上确保lsof安装成功，
sudo yum install -y lsof
安装
下载
wget http://mirror.qlangtech.com/4.0.0/tis/flink-tis-1.18.1-bin.tar.gz && rm -rf flink-tis-1.18.1 && mkdir flink-tis-1.18.1 && tar xvf flink-tis-1.18.1-bin.tar.gz -C ./flink-tis-1.18.1
启动Flink Cluster
cd ./flink-tis-1.18.1
./bin/start-cluster.sh确认端口是否正常
telnet localhost 8081
总结
恭喜您已经把Flink Standalone模式的集群安装成功了
caution
TIS中使用Flink Standalon模式是经过TIS团队适配过的，修改了Flink JobManager中ClassLoader执行逻辑，所以此处安装不能使用Flink官方发布的安装包
FAQ
1. Could not acquire the minimum required resources
在Flink中已经添加一个任务之后，再向Flink提交新的任务，Flink JM节点日志报告： Could not acquire the minimum required resources 没有足够的资源进行启动
原因：
Flink运行没有足够的slot资源分配给新任务
方法：
修改Flink配置文件:
{FLINK_HOME}/conf/flink-conf.yaml
# The number of task slots that each TaskManager offers. Each slot runs one parallel pipeline.
taskmanager.numberOfTaskSlots: 1
默认值是1，需要在单个Flink节点上运行多个Flink任务，课修改成大于1的值就行（一般情况slot代表了服务节点的资源并行处理能力，一般配置于节点CPU核数相一致即可）
2. 启动时候由于服务器目录/opt/data/tis没有权限，导致tis-flink启动失败(后台没有对应的进程在运行？)
原因：
tis系统日志默认输出到/opt/data/tis目录，如果当前启动用户没有权限创建此目录时，启动flink-tis时会启动失败，失败日志如下：
Caused by: java.io.IOException: Unable to create directory /opt/data/tis

修改方式是在一下配置文件加env.java.opts配置项

#具体目录根据自己情况修改
env.java.opts: "-Ddata.dir=/opt/data/tis"
3. 执行增量实例Cancel操作出现超时异常
象限描述：
本Case在创建增量实例时，使用了Chunjun Sink实现了整库表的同步功能，在手动取消（Cancel）实例过程中抛出以下异常，且一旦出现超时异常，Flink会将TM中剩下的全部slot耗尽，导致不能在重新部署新的Flink Job
2023-05-13 16:39:39,532 ERROR org.apache.flink.runtime.taskexecutor.TaskExecutor [] - Task did not exit gracefully within 180 + seconds.

原因分析：
由于Chujun Sink 在执行关闭时，需要为每张表对应的StreamLoadManager执行close操作，而该close执行又是比较耗时的，而且从日志执行过程来看每个表对应的close是线性排队执行的，所以当通道本身选择的表
数据量比较多的情况下，会出现超时异常也就不足为奇了。
解决办法：
在$FLINK_HOME/conf/flink-conf.yaml配置文件中设置 配置参数 task.cancellation.timeout，详细配置请查阅：https://study.sf.163.com/documents/read/service_support/dsc-t-d-0501
