Step by step to configure a web server in RHEL7

Install http package [I], start [S] package service, enable [E] service and test [T] service

[root@12c-rac-node2 ~]# yum install http -y
[root@12c-rac-node2 ~]# systemctl enable httpd
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
[root@12c-rac-node2 ~]# systemctl start httpd.service
[root@12c-rac-node2 ~]# systemctl status httpd.service
httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled)
   Active: active (running) since Mon 2016-03-14 13:09:07 BDT; 6s ago
 Main PID: 3054 (httpd)
   Status: "Processing requests..."
   CGroup: /system.slice/httpd.service

           ├─3057 /usr/sbin/httpd -DFOREGROUND
           ├─3058 /usr/sbin/httpd -DFOREGROUND
           └─3059 /usr/sbin/httpd -DFOREGROUND

Mar 14 13:09:07 12c-rac-node2 systemd[1]: Started The Apache HTTP Server.

[root@12c-rac-node2 ~]# firewall-cmd --add-port=80/tcp --permanent [---add port 80 to firewall to access from outside]
success
[root@12c-rac-node2 ~]# firewall-cmd --add-service=http --permanent [---add http service to firewall]
success
[root@12c-rac-node2 ~]# firewall-cmd --reload [---reload firewall service]
success
[root@12c-rac-node2 ~]#

Now create a index file in  /var/www/html location to test the web server

[root@12c-rac-node2 html]# vim index.html
[root@12c-rac-node2 html]# cat index.html
-----------This is a testing Website ----------------
[root@12c-rac-node2 html]#
[root@12c-rac-node2 html]# cat index.html
-----------This is a testing Website ----------------

Now testing the web server through command line url

[root@12c-rac-node2 html]# curl http://192.165.21.230
-----------This is a testing Website ----------------
[root@12c-rac-node2 html]#
[root@12c-rac-node2 html]# curl http://192.165.21.230:80   [---with specific port 80]
-----------This is a testing Website ----------------
[root@12c-rac-node2 html]#

######Configure web server with specific port#######

Here we will configure web server in 8008 port

[root@12c-rac-node2 html]# semanage port -l | grep http      [---check available port attached with http]
http_cache_port_t              tcp      8080, 8118, 8123, 10001-10010
http_cache_port_t              udp      3130
http_port_t                    tcp      80, 81, 443, 488, 8008, 8009, 8443, 9000
pegasus_http_port_t            tcp      5988
pegasus_https_port_t           tcp      5989
[root@12c-rac-node2 html]# firewall-cmd --permanent --add-port=8008/tcp   [add 8008 port with http]
success
[root@12c-rac-node2 html]# firewall-cmd --reload [---reload firewall service]  
success
[root@12c-rac-node2 html]# vim /etc/httpd/conf/httpd.conf       [---add listen port 8008]
[root@12c-rac-node2 html]# systemctl restart httpd.service [---restart http service]

[root@12c-rac-node2 html]# curl http://192.165.21.230:8008 [---check the web server through command line browser]
