How to Install\/Configure of Apache in Linux<\/h1>\n

Install Apache<\/h2>\n

First things first, your server may not even have Apache installed on it.<\/p>\n

Install the latest version with\u00a0yum<\/span><\/code>, like so:<\/p>\n

\n
\n
yum install httpd\r\n<\/pre>\n<\/div>\n<\/div>\n
\n
As with all CentOS\/Red Hat packages, \u2018latest\u2019 usually won\u2019t mean the current stable version that could be found on the project website<\/a>, but rather than latest package provided by CentOS\/Red Hat.<\/p>\n
These typically include backported security patches, see the page on vulnerability scans for further information.\u00a0Vulnerability Scans<\/span><\/p>\n<\/div>\n
Most people will want their webserver to start on boot, use\u00a0chkconfig<\/span><\/code>\u00a0to make it so:<\/p>\n
\n
\n
chkconfig httpd on\r\n<\/pre>\n<\/div>\n<\/div>\n
\n
Configure Virtual Hosts<\/h3>\n
Virtual Hosts are Apache\u2019s way of pointing different sites to different directories whilst still allowing them to share the same IP. If you\u2019re familiar with IIS parlance, then they\u2019d be called bindings.<\/p>\n
All config files ending in\u00a0.conf<\/span><\/code>\u00a0in the\u00a0\/etc\/httpd\/conf.d<\/span><\/code>\u00a0directory will be parsed as Apache configuration files at the end of the main\u00a0\/etc\/httpd\/conf\/httpd.conf<\/span><\/code>\u00a0file.<\/p>\n
The following content, if added to a file called\u00a0\/etc\/httpd\/conf.d\/vhosts.conf<\/span><\/code>\u00a0will enable multiple Virtual Hosts on one IP and then set up two sites, one called\u00a0firstdomain.com<\/span><\/code>\u00a0and the other called\u00a0seconddomain.org<\/span><\/code>.<\/p>\n
\n
\n
NameVirtualHost<\/span> *:80\r\n\r\n<VirtualHost<\/span> *:80<\/span>><\/span>\r\n   ServerName<\/span> firstdomain.com\r\n   ServerAlias<\/span> www.firstdomain.com\r\n   DocumentRoot<\/span> \/var\/www\/vhosts\/firstdomain.com\/public_html\/<\/span>\r\n   ErrorLog<\/span> \/var\/www\/vhosts\/firstdomain.com\/logs\/error.log<\/span>\r\n   CustomLog<\/span> \/var\/www\/vhosts\/firstdomain.com\/logs\/access.log<\/span> combined\r\n<\/VirtualHost><\/span>\r\n\r\n<VirtualHost<\/span> *:80<\/span>><\/span>\r\n   ServerName<\/span> seconddomain.org\r\n   ServerAlias<\/span> www.seconddomain.org\r\n   DocumentRoot<\/span> \/var\/www\/vhosts\/seconddomain.org\/public_html\/<\/span>\r\n   ErrorLog<\/span> \/var\/www\/vhosts\/seconddomain.org\/logs\/error.log<\/span>\r\n   CustomLog<\/span> \/var\/www\/vhosts\/seconddomain.org\/logs\/access.log<\/span> combined\r\n<\/VirtualHost><\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
The paths involved in that config likely don\u2019t exist, so you\u2019ll need to create them with the\u00a0mkdir<\/span><\/code>\u00a0command.<\/p>\n
\n
\n
mkdir -p \/var\/www\/vhosts\/firstdomain.com\/public_html\r\nmkdir -p \/var\/www\/vhosts\/firstdomain.com\/logs\r\nmkdir -p \/var\/www\/vhosts\/seconddomain.org\/public_html\r\nmkdir -p \/var\/www\/vhosts\/seconddomain.org\/logs\r\n<\/pre>\n<\/div>\n<\/div>\n
You\u2019ll also want to create the log files that you specified:<\/p>\n
\n
\n
touch \/var\/www\/vhosts\/firstdomain.com\/logs\/error.log \\<\/span>\r\n      \/var\/www\/vhosts\/firstdomain.com\/logs\/access.log \\<\/span>\r\n      \/var\/www\/vhosts\/seconddomain.org\/logs\/error.log \\<\/span>\r\n      \/var\/www\/vhosts\/seconddomain.org\/logs\/access.log\r\n<\/pre>\n<\/div>\n<\/div>\n
With a standard setup like this, the files will need to be owned by the Apache user and group:<\/p>\n
\n
\n
chown -R  apache:apache \/var\/www\/vhosts\/firstdomain.com \\<\/span>\r\n                        \/var\/www\/vhosts\/seconddomain.org<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
You\u2019re nearly good to go, the only thing you need now is some content. The Apache directive\u00a0DirectoryIndex<\/span><\/code>\u00a0specifies which file is used as the default index file in a directory, and by default this will be\u00a0index.html<\/span><\/code>\u00a0or\u00a0index.htm<\/span><\/code>. You may want to add\u00a0index.php<\/span><\/code>\u00a0into this line.<\/p>\n
By that logic, if you create a file in\u00a0\/var\/www\/vhosts\/firstdomain.com\/public_html\/<\/span><\/code>\u00a0called\u00a0index.html<\/span><\/code>\u00a0with some content, then that\u2019s what will display on\u00a0www.firstdomain.com<\/span><\/code><\/p>\n
\n
Don\u2019t forget to chown any website files to\u00a0apache:apache<\/span><\/code>\u00a0as well<\/p>\n<\/div>\n
In this example we\u2019ve added our vhost configurations into the\u00a0\/etc\/httpd\/conf.d\/vhost.conf<\/span><\/code>. When you have a lot of configuration files, it might be worth adding these into their own\u00a0.conf<\/span><\/code>\u00a0files. There will be examples of this at the bottom of this guide.<\/p>\n<\/section>\n
\n
Start it all up<\/h3>\n
All that remains now is to test your Apache configuration and then start the webserver up.<\/p>\n
Testing can be done with the command\u00a0httpd<\/span>\u00a0-t<\/span><\/code>\u00a0and if all is well, it should spit out the following message:<\/p>\n
\n
\n
Syntax OK\r\n<\/pre>\n<\/div>\n<\/div>\n
To start Apache, the following command can be used:<\/p>\n
\n
\n
service httpd start\r\n<\/pre>\n<\/div>\n<\/div>\n
Or if it\u2019s already running, you can restart it:<\/p>\n
\n
\n
service httpd restart\r\n<\/pre>\n<\/div>\n<\/div>\n<\/section>\n
\n
.htaccess files<\/h3>\n
Apache makes use of a file named\u00a0.htaccess<\/span><\/code>\u00a0in its document root to allow web server configurations to be made per-vhost without requiring access to the Apache configuration files. To allow these to work you need to configure the\u00a0AllowOverride<\/span><\/code>\u00a0settings by adding the following to your vhost configuration file.<\/p>\n
\n
\n
<Directory \"\/var\/www\/vhosts\/firstdomain.com\/htdocs\"><\/span>\r\n   Options FollowSymLinks<\/span>\r\n   AllowOverride All<\/span>\r\n\r\n   Order allow,deny<\/span>\r\n   Allow from all<\/span>\r\n<\/Directory><\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n<\/section>\n
\n
Going forward<\/h3>\n
Most sites now need more that just basic HTML, often using PHP to generate their dynamic content and some kind of database to store information.<\/p>\n
The following documents carry on the setup for those particular elements:<\/p>\n
