skywalking8.91升级到9.1注意注意事项

1、将skywalking8.9.1的进程kill -9 。

2、将skywalking9.1的代码拷贝到服务器，修改application.yml和webapp.yml，修改方法与skywalking8.9.1,参照我以前写的文章：https://blog.csdn.net/puzi0315/article/details/123243990

3、根据官方的介绍，说是要删除几个表，

https://skywalking.apache.org/docs/main/v9.1.0/en/faq/v9-version-upgrade/

但是好像不行。

4、折腾了很久，一直报错。

根据报错信息，指向es数据库， 我们的skywalking已经跑了一段时间了。

 

5、最后我清空了es里所有的索引，等个几分，skywalking才正常运行。

清空es所有索引的方法如下：

curl -X DELETE 'http://120.130.1.100:9200/_all'

ip地址为es地址。
