Install Apache on centos6 and open port 80

Install Apache 2

Apache2 is a centos software package, so we can directly install it using the following command:

Yum install httpd

Now configure the system to start Apache at boot

Chkconfig -- levels 235 httpd on

And start Apache

/Etc/init. d/httpd start

Now, go to http: // 192.168.0.100 in your browser and you should see the test page of apache2:

 

Apache 2 test webpage

Apache's default document root directory is on centos/Var/www/htmlDirectory. The configuration file is/etc/httpd/CONF/httpd. conf. Configure the directory stored in/etc/httpd/CONF. d.

4. Install PhP5

We can use the following command to install PhP5

Yum install PHP

Restart After installation

/Etc/init. d/httpd restart

Update centos firewall settings to enable port 80 access

The following is an example of adding port 80:

[Root @ centos httpd] #/sbin/iptables-I input-P TCP -- dport 80-J accept

Save

[Root @ centos httpd] #/etc/rc. d/init. d/iptables save

Iptables: Save the firewall rules to/etc/sysconfig/iptables: [OK]

If the above steps are not complete, it may be that the iptables file uses include call.

Generally, this path is/etc/sysconfig/iptables.

Or use VI to open the file and modify it.

[Root @ centos httpd] # vi/etc/sysconfig/iptables
