Logic datasync Redis and Mongo have issues and solution for high traffic?

duyanhstar

This is my config for mongo and redis:

{
        "url": "https://mydomain",
        "secret": "mykey",
        "database": "mongo",
        "mongo": {
          "host": "127.0.0.1",
          "port": "27017",
          "username": "nodebb",
          "password": "nodebb",
          "database": "nodebb",
          "uri": ""
        },
        "port": ["8900","8901","8902"],
        "bcrypt_rounds": "21",
        "bind_address": "127.0.0.1",
        "isCluster": "false",
        "redis": {
          "host": "127.0.0.1",
          "port": "6379",
          "password": "",
          "database": "2"
        },
        "session_store": {
                "name": "redis",
                "host":"127.0.0.1",
                "port":"6379",
                "password": "",
                "database": "1",
                "tls": {}
        }
}

I see a problem with data on NodeBB, ex: when i change site title in /admin/settings/general, it effect is true on FE and Admin. After 5 mins ( around), title will be changed to site title old, after 5 or 10 mins more, site title new back. Maybe, logic sync is not true?

Shooud i use "session_store" redis server for scale up with 10k users realtime? ( just thinking)

You are running more than 1 port so remove "isCluster": "false", or set it to true.

@baris said in Logic datasync Redis and Mongo have issues and solution for high traffic?:

You are running more than 1 port so remove "isCluster": "false", or set it to true.

I have a question more for using balancer loading on 5 dedicated servers.

Dedicated server 1: I setup nodebb run 3 on this port: 8900, 8901, 8902

{
        "url": "https://mydomain",
        "secret": "mykey",
        "database": "mongo",
        "mongo": {
          "host": "{server_DB}",
          "port": "27017",
          "username": "nodebb",
          "password": "nodebb",
          "database": "nodebb",
          "uri": ""
        },
        "port": ["8900","8901","8902"],
        "bcrypt_rounds": "21",
        "bind_address": "127.0.0.1",
        "isCluster": "true",
        "upload_path":"/home/public/uploads",
        "redis": {
          "host": "127.0.0.1",
          "port": "6379",
          "password": "",
          "database": "2"
        },
        "session_store": {
                "name": "redis",
                "host":"127.0.0.1",
                "port":"6379",
                "password": "",
                "database": "1",
                "tls": {}
        }
}

Dedicated server 2, 3 , 4, 5: i use one port: 8900. Then config on per server is

{
        "url": "https://mydomain",
        "secret": "mykey",
        "database": "mongo",
        "mongo": {
          "host": "{server_DB}",
          "port": "27017",
          "username": "nodebb",
          "password": "nodebb",
          "database": "nodebb",
          "uri": ""
        },
        "port": ["8900"],
        "bcrypt_rounds": "21",
        "bind_address": "127.0.0.1",
        "isCluster": "false",
        "upload_path":"/home/public/uploads",
        "redis": {
          "host": "127.0.0.1",
          "port": "6379",
          "password": "",
          "database": "2"
        },
        "session_store": {
                "name": "redis",
                "host":"127.0.0.1",
                "port":"6379",
                "password": "",
                "database": "1",
                "tls": {}
        }
}

I config true, right? What happending if a user upload a file to NodeBB, this file will be storaged on one server or 5 servers?

If you have multiple servers you should either use a upload plugin or setup a shared volume so all servers write files to the same location, otherwise uploads will be split among servers.

thanks you so much!
