一、升级的注意事项
将SR2.5升级到SR3.0
先升级BE，最后升级FE
FE的升级，先follower，最后leader
将原来2.5版本的lib和bin 备份， 新3.0的lib和bin放到对应的sr路径下，重启。
二、下载包
三、升级前的准备
- SR3.0安装包准备
- 参数调整
# 关闭tablet clone。关闭balancer
ADMIN SET FRONTEND CONFIG ("tablet_sched_max_scheduling_tablets" = "0");
ADMIN SET FRONTEND CONFIG ("tablet_sched_max_balancing_tablets" = "0")
ADMIN SET FRONTEND CONFIG ("disable_balance"="true") ;
ADMIN SET FRONTEND CONFIG ("disable_colocate_bpalance"="true");
四、BE升级（滚动升级）
-
停BE进程
-
原先路径备份
mv /data/starrocks/sr25/be/bin /data/starrocks/sr25/be/bin_25bak
mv /data/starrocks/sr25/be/lib /data/starrocks/sr25/be/lib_25bak
3. 复制3.0的lib到生产SR的路径下
cp -r lib /data/starrocks/sr25/be/
cp -r bin /data/starrocks/sr25/be/
4. 启动be进程
-
滚动操作下一个be节点
-
查看be集群

五、FE升级（滚动升级）
- 先操作follower
- 停止fe进程
# 关闭 fe 进程
systemctl stop starrocks_fe
3. 备份fe的lib和bin
mv /data/starrocks/sr25/fe/lib /data/starrocks/sr25/fe/lib_25bak
mv /data/starrocks/sr25/fe/bin /data/starrocks/sr25/fe/bin_25bak
mv /data/starrocks/sr25/fe/spark-dpp /data/starrocks/sr25/fe/spark-dpp_25bak
4. 将3.0同步到生产的sr路径下
cp -r lib /data/starrocks/sr25/fe
cp -r bin /data/starrocks/sr25/fe
cp -r spark-dpp /data/starrocks/sr25/fe
5. 启动fe进程
#
systemctl start starrocks_fe
6. 滚动重启下一个fe
-
最后升级leader
-
检查fe集群
#
show frontends;
六、收尾
# 升级后恢复参数
ADMIN SET FRONTEND CONFIG ("tablet_sched_max_scheduling_tablets" = "10000");
ADMIN SET FRONTEND CONFIG ("tablet_sched_max_balancing_tablets" = "500")
ADMIN SET FRONTEND CONFIG ("disable_balance"="false") ;
ADMIN SET FRONTEND CONFIG ("disable_colocate_bpalance"="false");
# 参数查看
ADMIN SHOW FRONTEND CONFIG LIKE "tablet_sched_max%";
ADMIN SHOW FRONTEND CONFIG LIKE "tablet_sched_max_scheduling_tablets";
ADMIN SHOW FRONTEND CONFIG LIKE "tablet_sched_max_balancing_tablets";
ADMIN SHOW FRONTEND CONFIG LIKE "disable_balance";
ADMIN SHOW FRONTEND CONFIG LIKE "disable_colocate_bpalance";
七、broker的升级
中间过渡版本，可以不升级。
最终升级到3.1的时候，broker再执行升级。
八、补充
2.5升级到3.1，需要3.0做个过渡，不然无法回滚。
所以2.5升级到3.0，然后过一段时间平稳无问题后，再升级到3.1。
滚动升级，一个一个节点操作。
