redis 远程连接时报错: 

Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect 

(redis 安装在ubuntu 系统)   – 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)
