server和client 运行后出现提示，改过端口号还是不行，要怎么办？

server和client运行后出现提示：Exception in thread "main" java.net.BindException: Address already in use: JVM_Bind，改端口号还是不好用，程序就是最简单的两个类建立连接的，要怎么办？

Answer 1

客户端和服务器应该分别启动两个jvm，eclipse一个时刻只能运行一个程序
你可以启动两个eclipse分别运行这两个程序(两次双击eclipse图标就可以，不过第二个要创建一个新的工作区workspace)。

解决方法

• 1.首先,我们要把防火墙禁用掉

• 2.安装redis时,Redis 的配置文件默认是绑定本地ip的,所以我们要去系统中找到bind 127.0.0.1,然后把它注释掉,那么就可以连接上了

• 3.下面是redis.conf配置文件,看到bind 127.0.0.1吗?就是他,搞我们连接不上,注释掉吧

  
  

• # Redis configuration file example

• # Note on units: when memory size is needed, it is possible to specifiy

• # it in the usual form of 1k 5GB 4M and so forth:

• #

• # 1k => 1000 bytes

• # 1kb => 1024 bytes

• # 1m => 1000000 bytes

• # 1mb => 1024*1024 bytes

• # 1g => 1000000000 bytes

• # 1gb => 1024*1024*1024 bytes

• #

• # units are case insensitive so 1GB 1Gb 1gB are all the same.

• # By default Redis does not run as a daemon. Use yes if you need it.

• # Note that Redis will write a pid file in /var/run/redis.pid when daemonized.

• daemonize yes

• # When running daemonized, Redis writes a pid file in /var/run/redis.pid by

• # default. You can specify a custom pid file location here.

• pidfile /var/run/redis/redis-server.pid

• # Accept connections on the specified port, default is 6379.

• # If port 0 is specified Redis will not listen on a TCP socket.

• port 6379

• # If you want you can bind a single interface, if the bind option is not

• # specified all the interfaces will listen for incoming connections.

• #

• bind 127.0.0.1

• # Specify the path for the unix socket that will be used to listen for

• # incoming connections. There is no default, so Redis will not listen

• # on a unix socket when not specified.

• #

• # unixsocket /var/run/redis/redis.sock

• 4.注释后,再重启redis服务器 sudo /etc/init.d/redis-server restart (不重启,你修改的配置不会生效)

我再运行代码

结果,输入出fucking 了..........

• fucking
