cd /data1/update_tidb tar xzvf tidb-community-server-v4.0.12-linux-amd64.tar.gz [root@host-172-21-210-40 update_tidb]# tiup -version v1.0.8 tiup Go Version: go1.13 Git Branch: master GitHash: 4276089 sh tidb-community-server-v4.0.12-linux-amd64/local_install.sh source /home/tidb/.bash_profile [tidb@host-172-21-210-40 update_tidb]$ tiup -version 1.4.0 tiup Go Version: go1.16.2 Git Ref: v1.4.0 GitHash: eb335e6ad9d0dc19d1c43db422cd409d62bc3cea

3、升级cluster

?

[root@host-172-21-210-40 ~]# tiup cluster --version Starting component `cluster`:  --version tiup version v1.0.8 tiup Go Version: go1.13 Git Branch: master GitHash: 4276089 [root@host-172-21-210-40 update_tidb]# tiup update cluster component cluster version v1.4.0 is already installed Updated successfully!

4、升级集群（根据数据多少来定时间，数据越多时间越长）
