操作步骤：

--1、解压安装包
cd /opt/soft/

tar -zxvf tidb-community-server-v7.5.0-linux-amd64.tar.gz 
tar -zxvf tidb-community-toolkit-v7.5.0-linux-amd64.tar.gz 

--查看当前集群状态
tiup cluster display tidb-xxx


--2、更新 TiUP 离线镜像
version=v7.5.0
sh tidb-community-server-${version}-linux-amd64/local_install.sh
tiup -v
--将 server 和 toolkit 两个离线镜像合并
ls -ld tidb-community-server-${version}-linux-amd64 tidb-community-toolkit-${version}-linux-amd64
cd tidb-community-server-${version}-linux-amd64/
cp -rp keys ~/.tiup/
tiup mirror merge ../tidb-community-toolkit-${version}-linux-amd64

--升级 Cluster 组件
tiup update cluster
tiup -v

--3、检查当前集群的健康状况
tiup cluster check tidb-xxx --cluster

--4、将集群升级到指定版本
tiup cluster upgrade tidb-xxx v7.5.0
--5、升级后验证
tiup cluster display tidb-xxx

执行第四步的时候报错，之前升级其他版本遇到过类似情况，是因为没有merge。这次确定merge了。

2

执行下：tiup list --all --verbose

3

组件的版本信息只会在本地无缓存的情况下从镜像服务器获取，可以通过 tiup list <component> 刷新组件列表。

4

7.5 里没有 tispark 包，去掉 tispark 试试

确实，7.5 里没有 tispark 包了，找了下升级到v6.5.1，这个版本还有tispark的包，升级成功。

6

tiup cluster upgrade 升级时如何指定不需要升级的组件，比如 tispark、nodeexporter等？

7

好像不能，没有-R吧

8

这个情况还蛮具体的，有些有升级包，有些没有升级包

10

@Damon-PingCAP 这个怎么去掉tispark，蹲个大佬的方法

11

缩容掉，spark 集群不应该通过 tiup 部署，tiup 里部署 spark 集群只是方便测试用的，与 tidb 集群也没关系。在离线包里 merge 一个包含 tispark 的版本镜像应该也可以。

12

这个问题确实有点具体了，学习一下。Spark 其实最好是手动部署。

13

多谢~
我理解错了，我以为是tiup cluster upgrade 升级过程中可以指定组件不升级 :joy:

14

学习了

15

学习了，可以先缩容掉，然后再升级
