I don‘t know if this is the right place to ask, but is this an OK build for a first start in selfhosting? Is there anything obvious I could improve? I‘d mainly run Nextcloud, Immich, some Docker containers and smaller web applications and cronjobs.

    I agree. The most limiting factor is still memory for me. And I’m max out currently of my motherboard (128gb).

    Recently thessecond limiting factor is actually cpu. But that is due to my gitlab runners.

        • I run 50+ websites
        • MariaDB instances
        • PostgreSQL instances
        • Docker containers
        • Mbin, Nextcloud, GitLab, GitLab runners, gitea, bitcoind, fulcrum, grafana, prometheus, influxdb, Synapse, Angie, telegraf and various other services like fail2ban etc. etc.

        All optimized for performance and fine tuned as well, eg. lets say you run mariadb vs how I run it:

        innodb_buffer_pool_size = 8G
        innodb_flush_log_at_trx_commit = 2
        innodb_log_file_size = 2G
        innodb_log_buffer_size = 32M
        innodb_max_dirty_pages_pct = 90
        innodb_io_capacity=5000
        innodb_io_capacity_max=20000
        innodb_read_io_threads=8
        innodb_write_io_threads=8
        query_cache_type = 1
        query_cache_limit = 2M
        query_cache_min_res_unit = 2k
        query_cache_size = 128M
        tmp_table_size= 128M
        max_heap_table_size= 128M
        
        [mysqld]
        max_connections = 200
        character_set_server = utf8mb4
        collation_server = utf8mb4_general_ci
        transaction_isolation = READ-COMMITTED
        binlog_format = ROW
        innodb_file_per_table=1
        # Increase open files based limits.conf value
        open_files_limit=65535
        

        Same idea for Postgresql… You can run “postgres” or… actually run postgresql in production correctly like:

        shared_buffers = 6GB
        work_mem = 20MB
        maintenance_work_mem = 2GB
        maintenance_io_concurrency = 200
        max_worker_processes = 14 
        max_parallel_workers_per_gather = 4
        max_parallel_maintenance_workers = 4
        max_parallel_workers = 12
        
        synchronous_commit = off
        commit_delay = 300
        
        checkpoint_timeout = 30min
        max_wal_size = 60GB
        min_wal_size = 4GB

          Actually now that I check your username I think I have seen your instances before, though it seems like your website is down at the moment. But thank you for service to open source !

                I block some misbehaving data centers. Which are often also used by VPN providers. So it’s more collateral damage.

                No I fully block some data centers not just rate limit.

                  Unfortunate but understandable. I believe there are public lists of the IPs of major VPN providers if you wanted to make an exception, but as VPNs are sometimes used for scraping too, I can see why you might not want that.

                    Yea so the same servers and IP addresses VPN provider use (which are again just cloud providers) are also used for other purposes mainly by scrapers and DDos attacks indeed. Too bad all those cloud providers do not act accordingly in the past 5 - 10 years. Since its getting worse and worse. With the increase of datacenters and centralization, I consider it a duty of these companies to take action to stop these scammers, spammers, scrapers, and attackers.

                    However, that is often not the case. Now I must say, I created Angie Guardian myself (alternative to Anubis). So hopefully soon I can slowly open some of ASN bans. And see how it goes.
