多次启动残留问题：重新删除旧pid配置

概述

1、命令行安装

bash 复制代码

wget https://github.com/milvus-io/milvus/releases/download/v2.6.21/milvus_2.6.21-1_amd64.rpm -O milvus_2.6.21-1_amd64.rpm

bash 复制代码

apt install -y  ./milvus_2.6.17-1_amd64.deb
# 或者
# dpkg -i milvus_2.6.17-1_amd64.deb

启动

bash 复制代码

systemctl start milvus

如果是在轻量容器中无法使用systemctl

bash 复制代码

/usr/bin/milvus run standalone

遇到问题

bash 复制代码

[2026/08/03 10:36:26.866 +08:00] [WARN] [grpclog/grpclog.go:155] ["[core][Channel #3 SubChannel #4] grpc: addrConn.createTransport failed to connect to {Addr: \"localhost:2379\", ServerName: \"localhost:2379\", }. Err: connection error: desc = \"transport: Error while dialing: dial tcp 127.0.0.1:2379: connect: connection refused\""]

bash 复制代码

apt update
apt install -y etcd-server etcd-client

启动etcd存储元数据

bash 复制代码

nohup etcd \
  --name milvus-etcd \
  --data-dir /var/lib/etcd \
  --listen-client-urls http://127.0.0.1:2379 \
  --advertise-client-urls http://127.0.0.1:2379 \
  --listen-peer-urls http://127.0.0.1:2380 \
  --initial-advertise-peer-urls http://127.0.0.1:2380 \
  --initial-cluster milvus-etcd=http://127.0.0.1:2380 \
  --initial-cluster-state new \
  > /var/log/etcd/etcd.log 2>&1 &

再次执行启动milvus命令

bash 复制代码

/usr/bin/milvus run standalone
