Multiple failed installs, please help! ! （API Error: EspoCRM API is unavailable.）

[snminvip]

I have installed it many times, and every time I encounter this problem, I don't know how to deal with it. Permissions and Nginx are set as per the documentation.

API Error: EspoCRM API is unavailable.

Hello,

Please send the error log of your nginx server.

[snminvip]

I tested and installed the latest project, and a white screen appeared after clicking install.

[lazovic]

Please check if the permissions and ownership are set correctly:

https://docs.espocrm.com/administration/server-configuration/#permissions

https://docs.espocrm.com/administration/server-configuration/#ownership

The permissions that have been detected are the current user permissions.

Hey Snmip,

Your log file says that there are write file permission errors. So there's definitely a problem there.

snminvip,

You said the permissions are set for current user.
Have you tried using www-data?

[MaxMax]

What do you mean by www-data

[lazovic]

Hi MaxMax,

All the EspoCRM files should be owned and group-owned by the webserver process. It can be www-data, daemon, apache, www, etc.

In most cases, it is www-data. It is the user that web servers on Ubuntu (Apache, nginx, for example) use by default for normal operation. The web server process can access any file that www-data can access.

To work with EspoCRM at the beginning, before installation, it is necessary to set the owner and group-owner, using these commands in terminal from your EspoCRM instance directory:

sudo chown -R <OWNER>:<GROUP-OWNER> .;

Instead of owner and group-owner you should insert, for example, www-data and www-data (without brackets).

The only thing that did it for me was to upgrade mariadb to the latest version. God knows why the error shows as API unavailable, but I decided to check the database version because there were errors related to it in the logs and I noticed i was running an old versions of MariaDB.
All is working now!!
