Estou tentando instalar o Discourse. Configurei meu banco de dados, Redis e SMTP. Para o PostgreSQL, não houve problema com o socket Unix, mas o Redis parece estar reclamando.

Configurações do Redis:

```
sudo sed -i 's/^# unixsocket /unixsocket /' /etc/redis/redis.conf
sudo sed -i 's/^# unixsocketp.*/unixsocketperm 770/' /etc/redis/redis.conf
sudo sed -i 's/^# maxmemory <bytes>/maxmemory 1024mb/' /etc/redis/redis.conf
sudo sed -i 's/^# maxmemory-policy noeviction/maxmemory-policy allkeys-lru/' /etc/redis/redis.conf
sudo cat /etc/redis/redis.conf | grep "^maxmemory\|^unixsocket"

```

Configurar o socket do Redis:  
`nano /var/www/discourse/config/discourse.conf`  
`redis_host = "/var/run/redis/redis-server.sock"`

Durante a instalação do Discourse:

`RAILS_ENV=production /root/.rbenv/versions/2.7.2/bin/bundle exec rake db:migrate`

```
