今天使用jedis客户端api连接远程连接redis/44580.html">redis/224808.html">redis的时候，一直报错，如下：

原来是redis默认只能localhost登录，所以需要开启远程登录。解决方法如下：
在redis的配置文件redis.conf中，找到bind localhost注释掉。
注释掉本机,局域网内的所有计算机都能访问。
band localhost 只能本机访问,局域网内计算机不能访问。
bind 局域网IP 只能局域网内IP的机器访问, 本地localhost都无法访问。
验证方法：
[root@mch ~]# ps -ef | grep redis root 2175 1 0 08:15 ? 00:00:05 /usr/local/bin/redis-server *:6379
/usr/local/bin/redis-server *:6379 中通过"*"就可以看出此时是允许所有的ip连接登录到这台redis服务上。
注意事项：
今天再设置远程访问的时候，在启动Redis的时候报错：Creating Server TCP listening socket *:6379: unable to bind socket（Redis一定不能设置成后台运行，否则终端不会有任何错误显示）。
上网搜索说各种原因的都有，有的说是Redis版本的bug(我用的版本是3.2.0)，我是参考以下几篇文章解决了这个问题：
https://github.com/antirez/redis/issues/3241
http://stackoverflow.com/questions/8537254/redis-connect-to-remote-server
我没有注释掉bind 127.0.0.1，而是将bind 127.0.0.1 改成了bind 0.0.0.0。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持VEVB武林网。
