How to Install Apache HTTP Server on CentOS



yum install httpd

Apache is most popular HTTP Server which runs on Linux & Windows based operating system. Let's see how to install and configure Apache HTTP Web Server on CentOS.


 

1. First update yum package

sudo yum -y update


2. Next, install Apache HTTP server

sudo yum install httpd


3. Start & Enable HTTP server (to start automatically on server reboot)

[centos@ ~]$ sudo systemctl start httpd [centos@ ~]$ sudo systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.


 

4. Now check the status of Apache server

[centos@ ~]$ sudo systemctl status httpd

httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Thu 2018-08-02 18:32:00 UTC; 6min ago Docs: man:httpd(8) man:apachectl(8) Main PID: 10235 (code=exited, status=0/SUCCESS) Aug 02 18:32:00 dataneb.com systemd[1]: Starting The Apache HTTP Server... Aug 02 18:32:00 dataneb.com httpd[10235]: httpd (pid 10202) already running Aug 02 18:32:00 dataneb.com kill[10237]: kill: cannot find process "" Aug 02 18:32:00 dataneb.com systemd[1]: httpd.service: control process exited, code=exited status=1 Aug 02 18:32:00 dataneb.com systemd[1]: Failed to start The Apache HTTP Server. Aug 02 18:32:00 dataneb.com systemd[1]: Unit httpd.service entered failed state. Aug 02 18:32:00 dataneb.com systemd[1]: httpd.service failed.


 

5. If server does not start, disable SELinux on CentOS

[centos@]$ cd /etc/selinux [centos@]$ sudo vi config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. # SELINUX=enforcing SELINUX=disabled # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted


 

6. Reboot the system to make SELinux changes effective

[centos@ ~]$ sudo reboot debug1: channel 0: free: client-session, nchannels 1 Connection to xx.xxx.xxx.xx closed by remote host. Connection to xx.xxx.xxx.xx closed. Transferred: sent 16532, received 333904 bytes, in 1758.1 seconds Bytes per second: sent 9.4, received 189.9 debug1: Exit status -1


 

7. Now check the status of Apache server again

[centos@ ~]$ sudo systemctl status httpd

httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2018-08-02 18:40:18 UTC; 35s ago Docs: man:httpd(8) man:apachectl(8) Main PID: 855 (httpd) Status: "Total requests: 0; Current requests/sec: 0; Current traffic: 0 B/sec" CGroup: /system.slice/httpd.service ├─855 /usr/sbin/httpd -DFOREGROUND ├─879 /usr/sbin/httpd -DFOREGROUND ├─880 /usr/sbin/httpd -DFOREGROUND ├─881 /usr/sbin/httpd -DFOREGROUND ├─882 /usr/sbin/httpd -DFOREGROUND └─883 /usr/sbin/httpd -DFOREGROUND Aug 02 18:40:17 dataneb.com systemd[1]: Starting The Apache HTTP Server... Aug 02 18:40:18 dataneb.com systemd[1]: Started The Apache HTTP Server.


 

8. Configure firewalld (CentOS is built by default to block Apache traffic)

[centos@ ~]$ firewall-cmd --zone=public --permanent --add-service=http [centos@ ~]$ firewall-cmd --zone=public --permanent --add-service=https [centos@ ~]$ firewall-cmd --reload


 

9. Test your url by entering Apache server ip address in your local browser
