一键管理 StarRocks：简化集群的启动、停止与状态查看

在日常运维中， StarRocks 集群的启动、停止与状态查看一直是一件颇为繁琐的事情.

想象一下，如果双十一前夕，StarRocks 集群在做例行压测。凌晨 3 点，监控告警：CPU 飙高，查询超时。值班同学第一反应是「重启试试」。

5 个 FE、8 个 BE，分布在 8 台服务器；

录到每台服务器，分别执行：

/fe/bin/start_fe.sh --daemon
/be/bin/start_be.sh --daemon

逐台 SSH，输入密码，执行 stop → start；
第 4 台机器输错路径，进程没起来，导致元数据不一致；
回滚、定位、修复，一共要花多少时间。更不要说跟多的服务器。

这种逐台操作的方式，不仅耗时，还容易出错。如果能一键启动、停止集群，并随时查看节点状态，效率将大大提升。

今天我来分享一个一键管理 StarRocks 的linux 的 shell脚本，实现以下功能：
一键启动 / 停止集群
统一查看 FE / BE 节点状态
动态配置节点，方便扩展
优点代码归一性

# StarRocks Cluster Management Script

# Author: tomxjc305
# Date: 2025-08-02
# Description: This script automates the start, stop, and status
#              check operations for a StarRocks cluster with dynamic configuration.
# =================================================================# --- Configuration Section ---# Define the FE and BE nodes dynamically in the environment variables or a configuration file.
# Example:
# export STARROCKS_FE_NODES="192.168.5.128 "
# export STARROCKS_BE_NODES="192.168.5.128 192.168.5.129 192.168.5.130"
# These can be configured by exporting environment variables in your shell or you can modify this section
# for more dynamic reading, such as from a configuration file.# --- Configuration from environment variables ---
