Error unable to open log file

I have exact same issue and i have literally tried EVERYTHING in this issue and more, have spent two days on this before i am writing this.

I have a NFS mount on the machine and i use docker-compose and use latest mosquitto. I have tried setting the owner to 1883:1883, i have tried to set permissions using chmod -R 777, i have tried to set the user: 1883:1883 and i also tried to set the

environment:
  - PGID=1883
  - PUID=1883

No matter what i do i get :

Error: Unable to open pwfile "/mosquitto/config/mosquitto.passwd".
Error opening password file "/mosquitto/config/mosquitto.passwd".
Error: Unable to open log file /mosquitto/log/mosquitto.log for writing.

Here is my docker-compose :

services:
  mosquitto:
      container_name: mosquitto
      restart: always
      image: eclipse-mosquitto:latest
      volumes:
        - "{{ app_data_dir }}/mosquitto/config:/mosquitto/config"
        - "{{ app_data_dir }}/mosquitto/data:/mosquitto/data"
        - "{{ app_data_dir }}/mosquitto/log:/mosquitto/log"
        - /etc/localtime:/etc/localtime:ro
      ports:
        - "1883:1883"
        - "9001:9001"
      networks:
        internal_net:
          ipv4_address: {{mosquitto_ip}}
      labels:
        - "traefik.enable=false"
      environment:
        - PUID=1883
        - PGID=1883
networks:
  proxy:
    external: true
  internal_net:
    external: true

Here is the output of the permissions and owner :

ansible@myvm-0-dev:~$ sudo ls -lR /var/docker_data/mosquitto
/var/docker_data/mosquitto:

drwxrwxrwx 1 1883 1883 102 Feb  3 16:57 config

-rwxrwxrwx 1 1883 1883 143 Mar 11 15:32 mosquitto.db

/var/docker_data/mosquitto/log:
total 0

Here is my NFS mount in fstab mount :

10.10.0.15:/volume1/docker_test /var/docker_data nfs rw,sync 0 0

If anybody has some idea more that has been described in this issue please do share since i don’t know what else i can try ? I can see the dockerfile sets the owner of the file to 1883 so even in the cases where i tries to run as another user the container sets the owner of the files to 1883.

I installed httpd on a CentOS 7 server, but systemctl start httpd.service is failing.

What specific sequence of commands need to be typed in order to get httpd to start correctly on CentOS 7?

Error Message

The precise error message extracted from the full results at bottom is as follows:

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain.   
Set the 'ServerName' directive globally to suppress this message  

Also, per @DopeGhoti’s suggestion, the contents of the logs are:

[root@localhost ~]# vi /var/log/httpd/error_log
(13)Permission denied: AH00091: httpd: could not open error log file /var/www/mytestdeployment/error.log.
AH00015: Unable to open logs
(13)Permission denied: AH00091: httpd: could not open error log file /var/www/mytestdeployment/error.log.
AH00015: Unable to open logs
(13)Permission denied: AH00091: httpd: could not open error log file /var/www/mytestdeployment/error.log.

How httpd was installed:

1.) Install Apache:

sudo yum -y install httpd

2.) Enable Apache as a CentOS service so that it will automatically restart on reboot:

sudo systemctl enable httpd.service

3.) Configure Firewalld

sudo firewall-cmd --zone=public --add-service=http
sudo firewall-cmd --list-all
sudo firewall-cmd --zone=public --permanent --add-service=http  

4.) Give the server a name:

vi /etc/httpd/conf/httpd.conf
//Uncomment the ServerName line and give it the IP of the machine:  
ServerName 192.168.1.5:80

The error message:

After installing httpd using the above commands, httpd is failing to start as follows:

[root@localhost ~]# systemctl start httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

@JeffSchaller’s suggestion

After @JeffSchaller suggested to consider SELinux, I found that typing setenforce 0 as root resulted in the following:

[root@localhost ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux
SELinux root directory:         /etc/selinux

[root@localhost ~]# setenforce 0
