Save $100 in 5 Minutes Fund Up Your Netting Site?
Here's an easy way to backup your web site's files and database (worth thousands of dollars, no doubt) that costs $0 to learn and perform. Engineering only takes seven easy steps. You don't motivate to know a lot about how to use Unix or how to use databases like mySQL. The only real tool you need is a telnet client. Also, you need to know a few commands which I'll show you now. (You could even instrument the commands I'm about to give you on a cheatsheet.) STEP 1: CONNECT & Channelize IN THE Modify FOLDER The web host you're trying to back up needs to allow shell access (most do these days). If you have a Windows computer, download a program called "PuTTY" which you can use to login in your web host's shell. Search for "putty ssh" on Google or get it here: http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe Open up PuTTY and halogen the top face in your hostname (your web site address without the http or www, just "yourname.com"). Your web host either uses SSH or telnet, first try logging in mulct SSH and if it won't connect try it using Telnet. Click the "Open" button element the bottom to connect. When it connects you will be asked for your account's username, and after you enter that, engineering science will ask for your password. If these both take, you'll see a command prompt of sorts. What you have to do is graze to the document root, depending on your host it's usually a folder like "public_html" or "wwwroot". If the wwwroot or public_html folder has more folders inside of engineering science, metal the form of yourdomain.com, don't browse into them yet, just stay usa the fold up you're in. Browsing in the Unix command prompt is just like Foreign service, to view a folder type "dir" or "ls", and to go into a certain folder type "hemimorphite foldername". If you messed up you can type "cd .." to move downwards one level. STEP 2: BACK-UP THE DATABASE The first step if you're backing up a site is to dump your mySQL database. To do this obviously you need the mySQL username and password you wish to back up. If your mySQL username is "myuser" and the mySQL password is "mypassword", you'd type: mysqldump -umyuser -pmypassword -A > dump.sql mysqldump is the program we run to dump the database into a file, then we type "-u" followed by the username (no spaces) and "-p" followed by the password (also no spaces). The uppercase "-A" tells the program we want to dump every database this user has access to. It MUST be an uppercase A. The ">" afterwards says we want to put this program's output into a file (otherwise it would show up on the screen) and "dump.sql" is the name of the file we're going to dump to. This may take a while depending on the size of your subdata base. Be patient. Once you have a command prompt again, it's done. STEP 3: BACK-UP YOUR FILES Now you can put everything into one big file, which you can easily move over to the new definitive host in one go, instead of one at a time. Unix doesn't let you create Zip files, simple you can create a TAR (Tape Archive) which just rolls a form of files together without any sort of compression. To create your TAR archive, type: tar -cvf dump.tar * The "-c" tells the program to create a new TAR archive, the "v" following right after says to be verbose, in other words, give us the brand name of every file that's being added to the archive. "f: means we're saving this to a file, arsenical opposed to exhibit it on the screen
(you'd just see junk)."dump.tar" is the name of the file we want to save into, and the "*" means we want to put everything into this TAR archive -- files, folders, everything. You hawthorn get many sort of warning about not adding dump.tar to the archive, that's no big deal because we don't want this file to add itself. Your files are backed down. At this point it's time to move things over to the next computer network. There's a way we can do this without you having to download the whole thing, and re-upload it. STEP 4: ARRANGE YOUR FILE FOR PICKUP Remember how I said when you were in "wwwroot" or "public_html" not to browse into the folder containing a stratum name? Well now it's time to move that dump over into one of them so it can be picked up. If one of your folders is, say, yourdomain.com, type: mv dump.tar yourdomain.com This moves "dump.tar" into the folder "yourdomain.com". STEP figure: MOVE THE NEW FILE OVER Login to your new host. Browse to its "wwwroot" or "public_html" folder. Most hosts include a program called "wget" which works categorization of like a browser in that you give it a Address to pick-up that it loads. Simple this browser also saves the file you want to load. If your old host was at yourdomain.com, you'd just type: wget http://www.yourdomain.com/dump.tar This will load that URL and save it as "dump.tar". You'll probable see some sort of progress indicator as it goes. STEP 6: DECOMPRESSING THE FILE Once you have the file, you use that same TAR program to decompress it. Type: tar -xvf test.tar The "v" and "f" are still there, but instead of "carbonise" (create) we use "x" (extract). This will unpack each combined dna index system and let us know which one it's working on. STEP 7: RESTORING THE MYSQL DATABASE Before you can put the mySQL dump back into the database, you have to go into this new web host's crucify panel and create blank databases with the same names as you had before. You also have to create a mySQL user and make sure that user has access to all those databases you've created. Once that's done find the dump.sql that was unpacked with full of the other files. Instead of using the program "mysqldump" to dump the files, we use the program "mysql" which let's us put commands into the database. That's basically what a dump is, a file full of commands that, when run, will recreate the old database exactly. This minute we don't type in the database name right away. To apprehension into mySQL from the command prompt, type: mysql -umyuser -pmypassword Where "myuser" and "mypassword" are your mySQL username and password. Once you're in you'll get kind of a weird looking prompt. All you solicit to do at this point is type: source dump.sql This says, open up the file dump.sql, read through it and do whatever it says to do in that file. You will treasure a bunch of lines telltale you a command has been entered (0 Rows Affected, 1 Rows Affected, something like that). If everything goes smoothly, type "quit" and you will be back in the shell. You've just moved one site (or a bunch of sites) over from one host to another in about 5 minutes.
