今天使用jedis客戶端api連接遠程連接redis/44580.html">redis/224808.html">redis的時候，一直報錯，如下：

原來是redis默認只能localhost登錄，所以需要開啟遠程登錄。解決方法如下：
在redis的配置文件redis.conf中，找到bind localhost注釋掉。
注釋掉本機,局域網內的所有計算機都能訪問。
band localhost 只能本機訪問,局域網內計算機不能訪問。
bind 局域網IP 只能局域網內IP的機器訪問, 本地localhost都無法訪問。
驗證方法：
[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 中通過"*"就可以看出此時是允許所有的ip連接登錄到這臺redis服務上。
注意事項：
今天再設置遠程訪問的時候，在啟動Redis的時候報錯：Creating Server TCP listening socket *:6379: unable to bind socket（Redis一定不能設置成后臺運行，否則終端不會有任何錯誤顯示）。
上網搜索說各種原因的都有，有的說是Redis版本的bug(我用的版本是3.2.0)，我是參考以下幾篇文章解決了這個問題：
https://github.com/antirez/redis/issues/3241
http://stackoverflow.com/questions/8537254/redis-connect-to-remote-server
我沒有注釋掉bind 127.0.0.1，而是將bind 127.0.0.1 改成了bind 0.0.0.0。
以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VEVB武林網。
