主机无法访问虚拟机上面安装的CentOS，上面安装的Oracle 10g

我是在虚拟机上面安装的CentOS，然后上面安装的Oracle 10g 有俩个实例，一个orcl,一个mydb
CentOS 在虚拟上面采用桥接方式，主机(主机ip 192.168.1.100,主机防火墙也关闭了)可以ping通虚拟机
刚刚试了下 lsnrctl status
[oracle@$ lsnrctl status

各位大哥能解释下什么意思吗？

Answer 1

你是要用主机上的sqlplus远程连接数据库还是单纯的使用类似secureCRT软件连接centos。如果是前者，你要首先保证数据库处于共享模式，在主机配置对应的tnsname.ora文件，关闭centos防火墙，保证在tnsping 虚拟机ip时出现OK字样（保证客户端与服务器连通）。后者的话，保证主机可以ping通centos就行

Answer 2

可以问下互易的技术

Answer 3

虚拟机防火墙关了吗

追问

关了，连本机和虚拟机的防火墙全部都关了
