CentOS is the most preferred alternative OS for RHEL. Those who cannot afford to purchase the support license of RHEL, they can use CentOS that comes with almost similar to RHEL. This post tells you about the usage of CentOS when web servers are installed and accessed from remote machines. CentOS is a Server based OS and most of the ports are closed by default and you need to open it for access from outside (remote). For ex. if wordpress is installed in CentOS with a hostname http://127.0.0.1/wordpress   which is very well accessed within the server. When the same is tried from outside like ( http://192.168.54.3/wordpress) , then it will not get accessed. The problem is the closure of ports in CentOS. So you need to open it and save it to iptables, here are the commands that will help you to do that. CentOS Port number : 80 is used here $prompt] ifconfig (find out which interface uses the assigned ip, eth1, eth0, etc) $prompt] iptables --line -vnL (See which line the input has to...

MySQL and MariaDB uses innoDB for storing the tables in a file format called Antelope.  For large sites, the Antelope format doesn't support more columns which makes the backup option a tedious process. so it will be advised to change the file format to Barracuda. There are various options to do that. Here is a small workaround to change it to barracuda. Open Mysql from the command prompt and execute the commands one by one $] mysql -u root -p The username is root here It will ask for the password: (Input the password here). mysql> select  version(); mysql> show variables like "%innodb_file%"; The output will be like this +--------------------------+----------+ | Variable_name            | Value    | +--------------------------+----------+ | innodb_file_format       | Antelope | | innodb_file_format_check | ON       | | innodb_file_format_max...

When Moodle is accessed either in Intranet or internet, there will not be any issue.

Once Moodle is stable, it will be put under licence. If it were any good, they’d already be charging for it Moodle needs a full time, php developer on your staff- or at least a lot of technical support to run it in house Moodle won’t be compatible with our other systems/software Moodle just doesn’t have the commercial experience we’re looking for You can’t just use Moodle out of the box – the basic Moodle install just isn’t that sophisticated There’s no documentation, training or technical support available – you’re on your own The Total Cost of Ownership is actually higher for Moodle than it would be with a wholly commercial platform Moodle is just no good for an institution as large as mine Moodle is just not designed to cope with my specific group of learners or customers We have all our stuff on *******, it’s just not worth the hassle of switching to Moodle Source: http://docs.moodle.org/en/Top_10_Moodle_Myths
