3-查看日志信息

?

cat /var/log/redis/redis-server.log
#提示Creating Server TCP listening socket ::1:6379: bind: Cannot assign requested addressoO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

4-初步分析

主機上禁用了IPv6，而Ubuntu的redis-server軟件包（版本5：4.0.9-1）附帶了：綁定127.0.0.1 :: 1

5-解決辦法

修改redis配置文件中的 bind 地址；注釋 bind 地址或將 bind 地址修改為 0.0.0.0

?

vim /etc/redis/redis.conf
// 注釋bind地址
#bind 127.0.0.1 ::1
//或修改bind地址-并允許其開放訪問
bind 0.0.0.0

6-啟動redis 服務

?

service redis-server start

7-檢查服務及端口

?

systemctl status redis-server
//提示信息

#Active: active (running) since Fri 2019-01-25 15:24:47 CST; 41min agonetstat -ntpl | grep 6379
