igrid 服务器 - 端口 19000 是什么？

最近我们的监控工具报告一个端口已关闭，端口号是19000。

我以前从未见过这个端口，也没有找到有用的信息。做了一些测试，我发现我可以使用 localhost 进行 telnet，但不能使用 ipaddres/hostname：

[root@server01 ~]# telnet 10.122.96.60 19000
Trying 10.122.96.84...
telnet: connect to address 10.122.96.60: Connection refused
[root@server01 ~]# telnet localhost 19000
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

此外，它还被一些 java 进程和 informix 数据库使用：

[root@server01 ~]# lsof -iTCP:19000

这是什么？我如何允许此端口进行远程连接（我们的监控工具）？最近，服务器已从物理机迁移到虚拟机，现在监控工具无法访问此端口。

具有/etc/services：

igrid           19000/tcp               # iGrid Server
igrid           19000/udp               # iGrid Server

您可以尝试使用ss和ps命令进一步检查。输出示例，将 12345 替换为您的 PID：

$ sudo ss -lntp | grep :19000
LISTEN  0  128  127.0.0.1:19000  0.0.0.0:*  users:(("program-name",pid=12345,fd=62))

$ sudo ps aux | grep 12345
oioki  12345  0.4  1.9 5132596 238256 ?  Sl  09:33  3:06 /full/path/to/your/program-name
