3 Mistakes Need to Avoid When Move Agen Domino Cloud

Agen Domino Cloud
Different ventures have committed enormous errors in their Agen Domino cloud organizations. Here they are, so you can abstain from committing a similar cloud-movement errorsThe vast majority of the accomplishment with your cloud arrangements originates from dodging the blunders that have cratered a few cloud ventures. I don’t need those of you perusing this blog to rehash similar errors.

Here are three regular missteps in cloud arrangements that you can, and should, Agen Domino abstain from making.

3 Mistakes Need to Avoid When Move into Agen Domino Cloud

Agen Domino Cloud

#1: Chasing the new sparkling items

Regardless of if it’s serverless or holders, ventures love what is new and hip. Albeit both serverless distributed computing and holders like Docker have a lot of significant worth, I frequently observe them utilized as a part of the wrong places for the wrong utilize cases.

Any new innovation that is drawing the consideration of the tech press, for example, machine adapting, profound learning, compartments, web of things, and serverless figuring—needs a decent business case which associates with a decent utilize case. Without both a decent business case and great utilize case, you could constrain square pegs into round gaps—regardless of how cool it is.

 

#2: Not considering devops

Moving to cloud? At that point you should move to a devops lifestyle, and to devops-empowering innovation, when you can. Why? http://idola99.com/ Since it will make your distributed computing movement more dexterous and speedier.

The truth is that many endeavors moving to cloud Agen Domino decrease the esteem they get from cloud in light of the fact that their current application improvement forms are as yet customary waterfall. In spite of the fact that the waterfall approach works, it doesn’t give the capacity to ceaselessly enhance application workloads or speed the generation and organization of new applications.

 

#3: Hiring for spending plan, not for ability

Regardless of in case you’re utilizing a counseling administration or procuring specifically, in case you’re going modest on distributed computing ability, you’ll get assets that will probably accomplish more mischief than great. Sparing $1 million in pay can cost you $100 million in avoidable screw-ups. I see this consistently.

Configure your Link Structure with YOURLS

Link structure

In the modern world of social media, people often try to say as much as they can with as few characters as possible. Especially with services such as Twitter limiting you to 140 characters, getting the message across in such a short message is a challenge. This gets harder still when you want to include hyperlinks in your message, allowing readers to click through for more information, as these links are often long and eat into that precious character allowance.

While a number of link-shortening services have appeared to aid in this – allowing you to shrink a hyperlink to fewer than 20 characters – these are often generic and anyone can shorten a link with them. This makes it impossible for a reader to know the legitimacy of a link before they click on it as they have no idea what domain they will end up clicking through to. Social media account hijackings mean that users are likely to be more cautious about these links.

So what is the solution?  Link shortening using your own domain is the ideal scenario, which is where YOURLS comes in. This is a web application that creates a forward for a short character combination through to a longer hyperlink. So rather than seeing a generic hyperlink that could be of questionable quality, the reader can now see a link with a domain name they trust – your domain – and know that only someone from your company could create that link.

YOURLS is a PHP application that uses a MySQL database to keep track of the links. This means that it can be used on any web hosting environment with PHP and MySQL. For the sake of this tutorial we are going to assume that you already have a server with  a LAMP or WAMP stack installed, and have created a Virtualhost for the domain you plan to use with YOURLS. You will also need to create a database for YOURLS to use.

The first thing to do is download the latest release from the YOURLS Github page: https://github.com/YOURLS/YOURLS/archive/master.zip

Unzip this file and copy the files contained within the YOURLS-master directory to the root of your virtual host or web hosting space.

You now need to copy the file “users/config-sample.php” to “users/config.php”. Once this is done you need to edit the config.php file and put in the details for your hosting environment.

This file is well documented, but you do need to go through all of the steps:

  • The first step is to set the details for the database that you are going to be using with YOURLS. You then need to define the domain name that you are configuring YOURLS to work with, i.e. the domain pointing to where you put these files.
  • Next, you need to provide your timezone’s offset from GMT. Then, if you need to use a different language than English, add the details of the translation file to use.
  • The next few settings can be left at their default. After that, you can enter a long string of random text to encrypt the YOURLS cookie data in the cookie key .

Next comes an important part: the creation of an array of username and password combinations for users who can log in and create shortening links. These are added in this file using plain text, but the first time that you use YOURLS after editing this file, the passwords will be transformed into a secure hash which will then overwrite the plain text version for password security. You can have as many ‘username’=>’password’ pairs here as you need for your site’s users.

The last few settings should be fine as they are for the rest of your usage. So save this file, and you are ready to get started. If you edited the file on your local computer, make sure you’ve uploaded it to your web space.
Now you can start using YOURLS: navigate in your browser to http://your-domain.com/admin/ replacing “your-domain.com” with the domain you have used for this site and you will be greeted with the login screen for your YOURLS admin. You can sign in using one of the username/password combinations you created earlier and start shortening URLs.

Setup MySQL Replication

MySQL Replication

Welcome back to our series on creating a highly available solution using VPSs on our public cloud. In the last part we looked at configuring Master-Master configuration for MySQL on the servers. We had the MySQL configuration set to listen for public connections to the server and configured the iptables firewall to only allow remote connections from the other server in the pair. Now we’ll conclude by setting the MySQL replication going on the servers.

How to set up MySQL replication

To get things going we need to create a user to perform the replication for MySQL. So first we need to log into the MySQL server as root on the first server:

mysql -u root -p

Once signed in, issue the following commands, making sure to adjust the IP address for your setup and change password for a secure password. The IP address should be the one of the second server. We are creating a user that MySQL will connect with from the second server to replicate data.

CREATE USER ‘repl_user’@’192.168.0.3’ IDENTIFIED BY ‘password’;

GRANT REPLICATION SLAVE ON *.* TO ‘repl_user’@’192.168.0.3′;

Now we need to get the position of the master log file: keep a copy of the output from this command:

SHOW MASTER STATUS;

With that done you can now exit the MySQL command line:

QUIT;

Now connect to the second server and repeat the process using the first server’s IP address to allow that to replicate in the other direction:

mysql -u root -p

CREATE USER ‘repl_user’@’192.168.0.2’ IDENTIFIED BY ‘password’;

GRANT REPLICATION SLAVE ON *.* TO ‘repl_user’@’192.168.0.2′;

SHOW MASTER STATUS;

Again, make a note of the master status information.

Now we can go back to the first server and start the replication, again by logging into the MySQL command line:

mysql -u root -p

Now run the following commands, changing the IP to match the second server’s IP, the password to match the password, the master log file to match the file shown in the SHOW MASTER STATUS output on the second server, and the MASTER_LOG_POS to match the second server’s position:

SLAVE STOP;

CHANGE MASTER TO MASTER_HOST = ‘192.168.0.3’, MASTER_USER = ‘repl_user’, MASTER_PASSWORD = ‘password’, MASTER_LOG_FILE = ‘filename.log′, MASTER_LOG_POS = XX;

SLAVE START;

Now you can check the status of its replication from the other server with:

SHOW SLAVE STATUS\G;

Note that the “\G” isn’t a typo, and is used to inform MySQL to provide a different output formatting which can make this command’s output more readable.

Finally, we repeat the process on the second server, noting that this time the IP address should be the one for the first server, and then that logfile and position should be the ones we got from the first server’s master status output:

SLAVE STOP;

CHANGE MASTER TO MASTER_HOST = ‘192.168.0.2’, MASTER_USER = ‘repl_user’, MASTER_PASSWORD = ‘password’, MASTER_LOG_FILE = ‘filename.log′, MASTER_LOG_POS = XX;

SLAVE START;

With that done, again you can check the replication status with:

SHOW SLAVE STATUS\G;

To test it you can make a change on one of the servers and see if it replicates over to the other server. To do that we’ll create a test database on the second server:

CREATE DATABASE test;

Now if you go back to the first server you can use the following command at the MySQL command line to see if the database copied over:

SHOW DATABASES;

The replication should be almost instant unless there are network issues between the servers.  If it doesn’t appear within a few minutes then you’ll need to check that the two servers are communicating ok.  Otherwise, if it replicated fine we can delete the database on the first server:

DROP DATABASE test;

With this done you can now go back over to the second server to check if the test database has been deleted:

SHOW DATABASES;

If it has gone then you are all good, and the Master-Master replication is working and successfully duplicating the database between each server. Next time we’ll look at how we can duplicate the files for our website between the servers using Unison.

How to Choosing Password Cryptdecrypt

alogaritm cryptdecrypt

It is absolutely necessary to choose a strong password to make sure that no one can decipher and decrypt your files. If you password based on a word from a dictionary or is short in length you are definitely putting yourself in a jeopardy. Anyone who would try to decrypt your files might run a dictionary check and then decrypting your files would be a matter of days. It is recommended that you use a long password containing numbers and non-dictionary characters, like “#”, “%” for example. In other words “password” is a bad choice for a password and “MN*ba5^001mqlw” is a good one.

Complexity vs. Password Length

Adding special characters to your password increases its complexity. This also makes passwords harder to hack but comes at the expense of making them harder to remember. When choosing between adding special characters or adding length to your password, longer passwords always win – they are stronger and more user-friendly than shorter passwords of greater complexity.

Picking a Passphrase

Passwords should be memorable, but not easily guessed. ITS recommends that you create a passphrase that is easy for you to memorize by combining a set of simple, unrelated words. You could simply choose words that you think of to create a passphrase; but a passphrase that is made from an unrelated series of words is inherently more secure because it is less likely to be guessed or cracked using brute force techniques.

And do not forget there rules about using the passwords:

1. Do not write your password anywhere
2. Do not tell anybody your password
3. Do not select weak password. Do not select password as a dictionary word, “12345”, “password” etc. Use digits, symbols and capital letters in the password.
4. When you choose password make sure it can not be guessed
5. If you suspect that someone might know your password change it.
6. Make sure that no one is looking over your shoulder when you enter the password.

Choosing a Strong Password

Passwords for your UNCG computing accounts are used to access many UNCG services, as well as your personal files, email, etc. So choosing a strong password and keeping it safe is important.

Longer Passwords Are Stronger

UNCG password policy requires the use of passwords between 16-30 characters. Passwords of this size may sometimes be referred to as “passphrases.” Passphrases can be easier for you to remember, while being more difficult for an attacker to guess.

In general, the longer your password is, the harder it is to be “hacked” (guessed or determined by password-hacking software). In fact, as you move from, say, an eight-character to a 16-character password, the length of time it would take a hacker to determine your password grows exponentially.
