2.\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo yum install httpd mod_ssl<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
3.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/span>Because the server doesn\u2019t start automatically when you install Apache, you must start it manually by using the following command:<\/span><\/span><\/p>\n
4.\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo \/usr\/sbin\/apachectl start<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
The following message displays:<\/span><\/p>\n
\u00a0 Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
5.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/span>Open the main Apache configuration file by using the following command:<\/span><\/span><\/p>\n
6.\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo nano \/etc\/httpd\/conf\/httpd.conf<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
7.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/span>Toward the end of the file, locate the code comment that starts with\u00a0<\/span>ServerName<\/span><\/code>\u00a0and provides an example name:<\/span><\/span><\/p>\n
8.\u00a0 <\/span><\/span><\/span><\/code>\u00a0#ServerName www.example.com:80<\/a><\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
9.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/span>Enter your Server host name. In the following example, the host name is\u00a0<\/span>demo<\/span><\/code>:<\/span><\/span><\/p>\n
10.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/span><\/span><\/span><\/code>\u00a0ServerName demo<\/span><\/code><\/pre>\n

11.\u00a0\u00a0<\/span><\/span>Reload Apache by using the following command:<\/span><\/span><\/p>\n
12.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo \/usr\/sbin\/apachectl restart<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
Open the port to run Apache<\/span><\/h3>\n
\u00a0<\/p>\n
Apache runs on port 80. In some versions of CentOS, a firewall that is installed by default blocks access to this port. Perform the following steps to open the port:<\/span><\/p>\n
1.\u00a0\u00a0<\/span><\/span><\/span>Run the following command:<\/span><\/span><\/p>\n
2.\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo iptables -I INPUT -p tcp --dport 80 -j ACCEPT<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
3.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/span>Use the following command to save your firewall rules so that your web server is accessible the next time that you reboot:<\/span><\/span><\/p>\n
4.\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo service iptables save<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
Test the Apache installation<\/span><\/h3>\n
\u00a0<\/p>\n
\u00a0<\/p>\n
Configure Apache to run automatically<\/strong><\/span><\/h3>\n
\u00a0<\/p>\n
After Apache is installed and working, use the following steps to set it to start automatically when the server is rebooted:<\/span><\/p>\n
1.\u00a0\u00a0<\/span><\/span><\/span>Run the following command:<\/span><\/span><\/p>\n
2.\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo \/sbin\/chkconfig httpd on<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
3.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/span>Run the following test to confirm that the setting works:<\/span><\/span><\/p>\n
4.\u00a0 <\/span><\/span><\/span><\/code>\u00a0sudo \/sbin\/chkconfig --list httpd<\/span><\/code><\/pre>\n
\u00a0<\/p>\n
<\/code><\/pre>\n
