Solved Upgrade to 1.17.2 and cluster configurtaion

[esfandiar]

Hello Everyone,

I finally migrated my code from 1.14.x baseline to work on 1.17.x on my windows development environment and trying to push changes to ubuntu-based production. After several failed attempt to upgrade from 1.14.x to 1.17.x on my ubuntu staging box, I started off fresh from 1.17.x and was able to build and run without my code. After linking my code and config, it stops loading with this error ONLY in clustered config:

./nodebb dev

Do I need to install Redis manually? My server is ubuntu 19.10 and running node v16.

Thanks for your support.

Yes install redis and add a redis block in your config.json like below

"redis": {
        "host": "127.0.0.1",
        "port": "6379",
        "password": "xxx",
        "database": "0"
    },

@baris said in Upgrade to 1.17.2 and cluster configurtaion:

"redis": {
"host": "127.0.0.1",
"port": "6379",
"password": "xxx",
"database": "0"
},

Thank you, will do as you instructed and report back.

@esfandiar
I ended up installing the latest OS and all required tool chain since support for ubuntu 19.10 has ended and repos are archived. Nodebb had no issues with Redis once the redis-server was started.
I still have unrelated issue with NPM not creating global links of my plugin folders and linking to the nodebb instance like it did before. My script creates links for each plugin project but only the last link is accessible and the rest disappearing. Possibly NPM and dependency issues but I am still investigating.

Thank you very much for your support.

Hi,

Do we need to make any changes to nginx configuration? I am having problem to connect to production server using my previously working nginx/network settings. Newly installed Nginx version is 1.18.0 and loads without error. Could you please advise if any additional Redis related changes is required.

Thank you in advance.

[baris]

@esfandiar No upgrading to 1.18.0 from 1.17.x should not require any changes to the nginx configuration. Can you share the nginx config that doesn't work? What errors are you getting or is it not loading at all?

Thank you so much for confirming this. Since my config was working before, I changed my focus only to network and found the issue.

In my nginx config I had:

listen 80
listen 443 default ssl

Miraculously this had worked for last four years without issue. My server has 4 nic cards and nginx was listening to the wrong interface.
Modified nginx config to bound it to the right ip:port to solve the issue.

Happy to be back on-line and thanks for your support.
