### Summary Redis database number 'redis_database' is ignored when you use socket instead of TCP, alway 0. Fix: Uncomment `redis_host` and `redis_port` + comment `redis_socket`, and it's ok But unix socket are faster than TCP. ### Steps to reproduce Use this config with a redis server (redis 6+) on the system : ### GitLab Redis settings ###! Connect to your own Redis instance ###! Docs: https://docs.gitlab.com/omnibus/settings/redis.html # Disable the bundled Redis redis['enable'] = false #### Redis TCP connection #gitlab_rails['redis_host'] = "127.0.0.1" #gitlab_rails['redis_port'] = 6379 gitlab_rails['redis_ssl'] = false gitlab_rails['redis_socket'] = '/run/redis/redis.sock' # defaults to /var/opt/gitlab/redis/redis.socket gitlab_rails['redis_database'] = '12' ### What is the current *bug* behavior? Database 0° (default) is selected instead of the value of `gitlab_rails['redis_database']` in `gitlab.rb` config ### What is the expected *correct* behavior? Select the correct database number with socket connection ### Gitlab version ### 14.10 ### Hardware Config ### Ubuntu server 21.10 on Ryzen 5900X with 64Go ECC ram, nvme disks ### Possible fixes Don't use socket, but not really a fix
