无法启动 php-fpm - “无法获取用户 'apache' 的 uid”

Question

On a fresh AWS Linux HVM box, I ran the commands:

sudo yum update
sudo yum install git nginx php-fpm

I then tried to sudo service start php-fpm , but got the error:

Starting php-fpm: [10-Sep-2014 20:52:39] ERROR: [pool www] cannot get uid for user 'apache'
[10-Sep-2014 20:52:39] ERROR: FPM initialization failed

Where am I going wrong and where is the apache user coming from?

Answer 1

The apache user comes from php-fpm.conf file. It does not matter that you run it as root, the service will start as the user which is configured in this file.

Find your php-fpm.conf file. It should be somwhere in /etc . Edit it and change lines

user = apache
group = apache

to

user = www-data
group = www-data

I'm assuming your default nginx configuration also uses the www-data user.

Answer 2

For a docker OpenShift no root way, prepare groups in build

vim /etc/groups

eg nobody:x:999:

it's after some update in php-fpm

Answer 3

Just adding for the latest ubuntu 18.04, it was a different user(magento) and was running on PHP 7.2.

Feb 12 14:33:23 same-cloud systemd[1]: Failed to start The PHP 7.2 FastCGI Process Manager.

From terminal,

sudo nano /etc/php/7.2/fpm/pool.d/magento.conf

I changed the contents as follows in the magento.conf file:

[magento]
user = www-data
group = www-data
listen.owner = www-data
listen.group = www-data
listen = /var/run/php/php7.2-fpm-magento.sock

In order to give effect, run the following commands:

sudo systectl restart apache2

To see the status

systemctl status php7.2-fpm.service

Additional commands to enable fpm

a2enmod proxy_fcgi setenvif
sudo a2enconf php7.2-fpm
