Strange error with Apache on CentOS 7
As user ezra-s already mentioned SELinux was the culprit. As soon as I executed
sudo setenforce 0
sudo systemctl start httpd.service
Everything started working. I will disable SELinux permanently since this is pure test VM.
Thanks everybody.

I am trying to build virtual machine using vagrant, virtualbox and CentOS 7 64bit. Host OS is Ubuntu 14.04 64bit. Vagrant is 1.9.2, VirtualBox 5.1.6.
Here is the Vagrantfile
Vagrant.configure("2") do |config| config.vm.box = "centos/7" config.vm.box_check_update = false # Enable cache if plugin is installed # To install it execute: vagrant plugin install vagrant-cachier # cache will be located in [thisvagrantdir]/.vagrant/machines/default/cache if Vagrant.has_plugin?("vagrant-cachier") config.cache.auto_detect = true config.cache.scope = :machine end config.vm.network "private_network", ip: "192.168.33.101" config.hostmanager.enabled = true config.hostmanager.manage_host = true config.hostmanager.aliases = %w(centos7.dev) config.ssh.forward_agent = true config.vm.synced_folder ".", "/vagrant", type: "nfs" config.vm.provider "virtualbox" do |vb| vb.customize ["modifyvm", :id, "--memory", "2048" ] vb.customize ["modifyvm", :id, "--name" , "centos7"] end config.vm.provision "shell" do |s| s.privileged = true s.path = "provisioner.sh" end end
Now in the provisioner.sh I install PHP, some extensions and add one config file for apache located in /etc/httpd/conf.d/site.conf . Here is the site.conf:
<VirtualHost _default_:80> ServerAdmin [email protected] DocumentRoot /vagrant/www/moodle ServerName centos7.dev ErrorLog /vagrant/log/error.log CustomLog /vagrant/log/requests.log combined <IfModule dir_module> DirectoryIndex index.php index.html </IfModule> <Directory /vagrant/www/moodle> Options All AllowOverride All Require all granted </Directory> <Location /> LogLevel warn </Location> </VirtualHost>
/vagrant/www/moodle is NFS attached dir from host system.
After all this is done apache just refuses to start. I can run sudo systemctl start httpd.service 100 times and nothing happens. However if I run it with sudo httpd it works???!!!
This is what I get as status
[vagrant@default ~]$ sudo systemctl status httpd.service ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since mar 2017-05-09 11:29:09 UTC; 8s ago Docs: man:httpd(8) man:apachectl(8) Process: 7149 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE) Process: 7148 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 7148 (code=exited, status=1/FAILURE) may 09 11:29:09 default systemd[1]: Starting The Apache HTTP Server... may 09 11:29:09 default systemd[1]: httpd.service: main process exited, code=exited, status=1/FAILURE may 09 11:29:09 default kill[7149]: kill: cannot find process "" may 09 11:29:09 default systemd[1]: httpd.service: control process exited, code=exited status=1 may 09 11:29:09 default systemd[1]: Failed to start The Apache HTTP Server. may 09 11:29:09 default systemd[1]: Unit httpd.service entered failed state. may 09 11:29:09 default systemd[1]: httpd.service failed.
Any ideas as to what I'm doing wrong here? Thanks

Admin almost 7 yearswell, check if
/vagrant/log/
exists and it is writable by httpd. Supposedly httpd runs as root for this but if the directory is present chances are SELinux is not allowing it. -
Admin almost 7 years/vagrant/log exists and it has 777 mask. I will try disabling selinux
