在k8s 上部署golang 的 grcp 服务端,
客户端是 php grpc 扩展
问题 : 客户端 connction reset by peer 的情况 ,
利用了tcp本身的keepalive 包来保活,也修改了 net.ipv4.tcp_keepalive_time 等参数,但是还会频繁出现断连的问题,
```go
func main() {
grpcServer := grpc.NewServer(
grpc.KeepaliveParams(keepalive.ServerParameters{Time: 600 * time.Second}),
grpc.MaxConcurrentStreams(10000),
)
protoc.RegisterTServiceServer(grpcServer, new(handle.TImpl))
reflection.Register(grpcServer)
addr := startcfg.GetLisAddr()
lis, err := net.Listen("tcp4", addr)
if err != nil {
panic(err)
}
grpcServer.Serve(lis)
}
```
pod中内核参数
```shell
sysctl -a|grep tcp_keepalive
net.ipv4.tcp_keepalive_intvl = 30
net.ipv4.tcp_keepalive_probes = 10
net.ipv4.tcp_keepalive_time = 600
sysctl: reading key "net.ipv6.conf.all.stable_secret"
sysctl: reading key "net.ipv6.conf.default.stable_secret"
sysctl: reading key "net.ipv6.conf.eth0.stable_secret"
sysctl: reading key "net.ipv6.conf.lo.stable_secret"
```
机器上的 值也改了,求大佬给出一些思路
