dpkg: error processing package redis-server (--configure): installed redis-server package post-inst

阿里云 Ubuntu18 安装Redis报错如下：

dpkg: error processing package redis-server (--configure):  installed redis-server package post-installation script subprocess returned error exit status 1 Errors were encountered while processing:  redis-server E: Sub-process /usr/bin/dpkg returned an error code (1)

原因：redis默认启用IPv6，但是普通的阿里ECS是不支持的

解决：sudo vim /etc/redis/redis.conf

Simply remove the ::1 IPv6 loopback address from the bind config option:

- bind 127.0.0.1 ::1
+ bind 127.0.0.1
