Cacti service failed to start.

Post by bogdan »

Hello team,

I am a new in Cacti. I tried to install Cacti following this article https://docs.cacti.net/Installing-Under ... units-file but when I try to start service using command "systemctl start cactid" I getting below error:

Job for cactid.service failed because the control process exited with error code.
See "systemctl status cactid.service" and "journalctl -xeu cactid.service" for details.


In output of systemctl status cactid.service I see below:

Job for cactid.service failed because the control process exited with error code.
See "systemctl status cactid.service" and "journalctl -xeu cactid.service" for details.

I tried to follow this artticle https://github.com/Cacti/cacti/commit/9 ... e6b2eb7077 but used username "www-data" instead of username from artcile becasue I do not have such user in system. By the way I found this video https://www.youtube.com/watch?v=Ggpwvd2GV1E where username "www-data" is used. Unfortunately steps in article or video did not help me.

Please advice how to troubleshoot this?

Thanks.

Edit the cactid.service file in /etc/system/systemd and change the user to the correct user, I think www-data, then perform a systemctl daemon-reload followed by systemctl start cactid. Make sure that the entire Cacti website is owned by www-data.

Hello,

Thanks for the reply.

I do not have such folder /etc/system/systemd, but I have service in this folder /var/www/html/cacti/service/cactid.service.

cactid.service file already have correct user. Below what I have in the file:

[Unit]
Description=Cacti Daemon Main Poller Service
After=network.target

[Service]
Type=forking
User=www-data
Group=www-data
EnvironmentFile=/etc/cactid
ExecStart=/var/www/html/cacti/cactid.php
Restart=always
RestartSec=5s

[Install]
WantedBy=multi-user.target



Could you please advice what you mean about "Make sure that the entire Cacti website is owned by www-data"? Where I can check it?

Thanks in advance.

ls -al /var/www/html/cacti
You check second and third columns. It is user and group (it should be www-data in your case)

Thanks for the quick reply.

I see that all files owned by another user. Please see below part of the output:

So in this case I have to change ownership for /var/www/html/cacti to www-data right?

I tried to do that. Now I have changed ownership:

I ran commands systemctl daemon-reload and systemctl start cactid but still service failed to start.

When I run php -q -d display_errors=on ./cactid.php I getting below error:


FATAL: Connection to Cacti database failed. Please ensure:

- the PHP MySQL module is installed and enabled.
- the database is running.
- the credentials in config.php are valid.



I tried to check PHP and looks loke it is running:

bogdan@cacti:/var/www/html/cacti$ php -v
PHP 8.3.14 (cli) (built: Nov 25 2024 18:07:16) (NTS)

bogdan 21853 0.0 0.1 6480 2304 pts/0 S+ 18:25 0:00 grep --color=auto php



The Database is running. I can logging to DB:

bogdan@cacti:/var/www/html/cacti$ sudo mysql -u root -p
[sudo] password for bogdan:
Sorry, try again.
[sudo] password for bogdan:

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>



I found config.php in this folder /var/www/html/cacti/include/

Here is part of the config.php file where there is credentials:


$database_type = 'mysql';
$database_default = 'cacti';
$database_hostname = 'localhost';
$database_username = 'cactiuser';
$database_password = 'cactiuser';
$database_port = '3306';
$database_retries = 5;
$database_ssl = false;
$database_ssl_key = '';
$database_ssl_cert = '';
$database_ssl_ca = '';
$database_persist = false;



I found that I can open DB with command sudo mysql -u root -p -h localhost cacti

But I cannot if use cactiuser from config.php file

Also I tried change username and password to root username and password - this did not help me.

Could you please advice what I am doing wrong?

Thanks.
