Using Ruby On Rails on Bluehost:
This is intended to be a brief introduction to developing ruby on rails applications on a bluehost account. at the bottom of this article you will find a number of resources to help you learn more about ruby on rails and related information, as well as links to some rails tutorials that will go into more depth than this document.

BlueHostis the domestic user to choose moreUS hostOne, especially by foreign trade customers favor. In the domestic access speed is excellent, the host all aspects of stable operation. With a unique advantage in the global IDC mainframe market influence is undoubtedly, with a distinctive style deep into the Chinese market. Along the way, BlueHost in the technical pursuit of continuous innovation, in the service to improve the pre-sales, after-sales su
Bluehost registration process and Problems
Step 1
Go to the bluehost official website and click sign up now in pink to register
Step 2
After entering the next interface, you can get a new domain name for free. bluehost will give you a free domain name for the first year, So enter the domain name you want and click OK.
Step 3
If the domain name you entered ha
This article is a little more up to date with the changes made by hostmonster/bluehost, and to make the instructions a little more clear, and simplified.

I found it easier to extract the files on my desktop then upload them to a directory called MongoDB IN THE ROOT home folder.
Notes for ordering an independent server:
1. Note that it is important to enter account information and credit card information truthfully. Otherwise, the review will take a long time.
2. when registering an account, you must enter the domain name. If you have a domain name, select the second one. If not, select the first one. The first box allows you to apply for a domain name for free as your account name. this requires binding a lot of information to your server. Without this domain name, i

Comparison of multiple foreign Virtual Hosts
I recently tried several foreign virtual hosts. here we will not talk about very specific parameters, but just my feelings. as hosts are abroad, there is a high possibility of being harmonious, so an independent IP address is required for website stability.
Bluehost:
Parameter: unlimited space, no traffic, no site establishment, no FTP user count, 100 databases, and support for ssh. In general, there i

Default php.ini file for virtual hosts
Bluehost cpanel can generate a default php.ini configuration file, if you need to make some special settings, you can download the file after the local edit the file upload to the appropriate directory, the edits are effective immediately.
Methods for generating php.ini:
Login cpanel–>software/services–>php config–>
Select: Install Default php.ini, which will generate a standard configuration file named: Php.ini.

The original optimization problem can be converted to the minimum eigenvalues and eigenvectors of B, the specific code:
