向量库Milvus异常挂了，重新启动

1. 检查 Milvus 服务状态   docker ps -a | grep milvus

[root@localhost ~]# docker ps -a | grep milvus
3f4be056538e   milvusdb/milvus:v2.4.9                     "/tini -- milvus run…"   2 months ago   Exited (1) 3 hours ago             milvus-standalone

[root@localhost ~]#

Milvus 及其相关服务（如 MinIO 和 etcd）的容器都已经退出。具体来说：

• milvus-standalone 容器退出状态为 1，这通常表示容器在启动过程中遇到了错误。
• milvus-minio 和 milvus-etcd 容器都已正常退出（状态 0），但这也意味着它们没有运行。

2. 查看端口号  netstat -tuln | grep 19530

(base) [root@localhost ~]# netstat -tuln | grep 19530
(base) [root@localhost ~]# 

没反应，端口（19530）上没有进程在监听

3. 重新启动服务

docker start b06e301d446c  # 启动 MinIO
docker start a50e3b1bafdb  # 启动 etcd

docker start 3f4be056538e  # 重新启动 Milvus

(base) [root@localhost ~]# docker start b06e301d446c
b06e301d446c
(base) [root@localhost ~]# docker start a50e3b1bafdb
a50e3b1bafdb
(base) [root@localhost ~]# docker start 3f4be056538e
3f4be056538e

4. 再一次查看端口号： netstat -tuln | grep 19530

(base) [root@localhost ~]# netstat -tuln | grep 19530
tcp        0      0 0.0.0.0:19530           0.0.0.0:*               LISTEN     
tcp6       0      0 :::19530                :::*                    LISTEN

5. 检查 Milvus 服务状态   docker ps -a | grep milvus

(base) [root@localhost ~]# docker ps -a | grep milvus
