无法在Ubuntu 18.04上安装Redis服务器

ubunturedisredis-server

我已将系统从17.10升级到ubuntu 18.04，但是redis-server软件包无法完全安装。我查看了/var/log/syslog文件，上面写着：

然而，它超时了并且没有启动redis守护进程。配置文件是随包提供的。

我尝试手动创建pid文件并赋予它大量权限，但似乎没有起作用。
sudo touch /var/run/redis/redis-server.pid
# sudo chown redis:redis /var/run/redis/redis-server.pid
# sudo chmod 777 /var/run/redis/redis-server.pid
# sudo ls -alh /var/run/redis/

即使禁用IPv6，也可以运行redis-server。

只需从bind配置选项中删除::1 IPv6环回地址（默认位于/etc/redis/redis.conf）：

- bind 127.0.0.1 ::1
+ bind 127.0.0.1

现在Redis将不会尝试使用IPv6网络。

这是正确的答案。要根据环境调整 Redis，而不是反过来。 - GerardJP

我找到了问题的原因。我之前禁用了IPv6。我重新启用了它，然后就安装和启动成功了。如果redis仅支持IPv4模式，你可以尝试修改redis.conf文件以强制其使用IPv4，可能这样就能在不开启IPv6的情况下运行。

请接受这个答案，因为问题不再需要关注。 - Imaskar
这对我也起作用了。在我的情况下，我编辑了 /etc/sysctl.conf 文件并删除了以下行：net.ipv6.conf.all.disable_ipv6 = 1。 - Tarek Loubani

我也曾尝试安装redis-server，但无论怎样都失败了。最终，我通过在Windows上使用Ubuntu完成了安装，以下是具体步骤：

sudo apt-add-repository ppa:redislabs/redis
sudo apt-get update

请确保您已经安装了redis-tools和libglib2.0-0。如果没有，请安装以下软件包：

sudo apt-get install redis-tools
sudo apt-get install -y libglib2.0-0

接下来：

sudo apt-get install redis-server

然后这样启动Redis服务器：

sudo service redis-server start

好的，我刚刚遇到了从Ubuntu 16.04升级到18.04的类似问题。上面的解决方案（禁用ipv6）在这里没有帮助。可能是我的问题，但我也不明白为什么会有帮助，因为错误的重要部分似乎是
Jun  3 13:05:40 qaz-mko systemd[1]: redis-server.service: Can't open PID file /var/run/redis/redis-server.pid (yet?) after start: No such file or directory

显然，仅仅创建文件本身并不能解决这个问题。但是有帮助的是，创建目录并赋予必要的权限：
mkdir -p /var/run/redis
chown redis:redis /var/run/redis

它不能在重启后保留。虽然我仍在努力寻找解决方案，但快速而简单的解决方法是将上述行放入rc.local中。

可能从systemd单元/etc/systemd/system/redis-cluster-node@.service中删除PID可以帮助解决问题
