odoo services monitor
Hi
I need UR help; I have server CentOS7 installed with odoo12,
But some time odoo service stopped without any reason!
So I searched in many websites and i reached to this module ( Monit )
and I want to use it to fix my issue
HOW can I use it to monitor odoo services if its stop, make restart automatically ?
Hi, you can try to use the …
Hi, you can try to use the "Mariadb" configuration above as reference guide for your odoo services Monit configuration.
MongoDB Error
Getting this error on the MongoDB File

Do you have mongo service…
Do you have mongo service installed in your server? Make sure that /usr/bin/mongod exist.

In reply to please add php-fpm configuration using unix socket by swevel (not verified)
The same configuration
The configuration for php-fpm config using unix socket is the same as the PHP-FPM configuration in this article. The followng are just labels:
... you can rename those to:php-fpm-tcp
php-fpm-tcp_bin
php-fpm-tcp_init
php-fpm-unix
php-fpm-unix_bin
php-fpm-unix_init
if failed host
In the "if failed host" is it the sane if we write the IP address of the server?
