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？

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..........
