ubuntu安装redis-server报错解决

今天在ubuntu上使用apt-get安装redis-server。报如下错误：

Do you want to continue? [Y/n] Y

Job for redis-server.service failed because a timeout was exceeded.

E: Sub-process /usr/bin/dpkg returned an error code (1)

后来发现是系统禁用了ipv6的原因。

解决方法:

取消禁用ipv6，修改/proc/sys/net/ipv6/conf/eth0/disable_ipv6的状态即可。

也可以作永久取消处理

vim /etc/sysctl.conf 

#net.ipv6.conf.all.disable_ipv6 = 1  #注释这条。
net.ipv6.conf.eth0.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1      

保存完毕，执行下面的命令使其生效。

sysctl -p 

重新安装redis-server，OK。
