第一台服务器hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.20.152.181  localhost localhost.localdomain localhost6 localhost6.localdomain6
10.20.152.181 orderer.example.com
10.20.152.182 peer0.org1.example.com
10.20.152.180 peer0.org2.example.com
127.0.0.1 orderer.example.com

且开放了端口

[root@localhost fabric]# docker ps -a
CONTAINER ID        IMAGE                        COMMAND             CREATED             STATUS                  PORTS                    NAMES

防火墙也关了

[root@localhost fabric]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

但是第二台182服务器防火墙也关了，hosts设置如下：

ping得到181

[root@localhost ~]# ping 10.20.152.181

^Z
[2]+  Stopped                 ping 10.20.152.181

却连接不到181的，请问如何解决，谢谢。
