今天使用jedis客戶端api連接遠(yuǎn)程連接redis的時(shí)候，一直報(bào)錯(cuò)，如下：

原來是redis默認(rèn)只能localhost登錄，所以需要開啟遠(yuǎn)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(jī),局域網(wǎng)內(nèi)的所有計(jì)算機(jī)都能訪問。
band localhost?? 只能本機(jī)訪問,局域網(wǎng)內(nèi)計(jì)算機(jī)不能訪問。
bind? 局域網(wǎng)IP??? 只能局域網(wǎng)內(nèi)IP的機(jī)器訪問, 本地localhost都無法訪問。
驗(yàn)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(shí)是允許所有的ip連接登錄到這臺(tái)redis服務(wù)上。
注意事項(xiàng)：
今天再設(shè)置遠(yuǎn)程訪問的時(shí)候，在啟動(dòng)Redis的時(shí)候報(bào)錯(cuò)：Creating Server TCP listening socket *:6379: unable to bind socket（Redis一定不能設(shè)置成后臺(tái)運(yùn)行，否則終端不會(huì)有任何錯(cuò)誤顯示）。
上網(wǎng)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)，我是參考了幾篇文章解決了這個(gè)問題：
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Redis打開遠(yuǎn)程登錄連接的全部?jī)?nèi)容，更多精彩內(nèi)容，盡在https://js.Vevb.com。
