If your apache is talking to PHP through a TCP socket (127.0.0.1:9000) instead of a Unix socket (/run/php/php7.1-fpm.sock), you will need to modify the following line:
# sudo vim /etc/apache2/conf-available/php7.3-fpm.conf
# Define a matching worker.
# The part that is matched to the SetHandler is the part that
# follows the pipe. If you need to distinguish, "localhost; can
# be anything unique.
<Proxy "fcgi://localhost/" enablereuse=on max=10>
</Proxy>
<FilesMatch ".+\.ph(ar|p|tml)$">
#SetHandler "proxy:unix:/run/php/php7.3-fpm.sock|fcgi://localhost"
SetHandler "proxy:fcgi://127.0.0.1:9000"
</FilesMatch># sudo apache2ctl configtest

Make sure you’re in your home directory, then retrieve the installer using curl:
Next, we’ll verify that the downloaded installer matches the SHA-384 hash for the latest installer found on the Composer Public Keys / Signatures page. To facilitate the verification step, you can use the following command to programmatically obtain the latest hash from the Composer page and store it in a shell variable:
If you want to verify the obtained value, you can run:
Outpute0012edf3e80b6978849f5eff0d4b4e4c79ff1609dd1e613307e16318854d24ae64f26d17af3ef0bf7cfb710ca74755a
Now execute the following PHP code, as provided in the Composer download page, to verify that the installation script is safe to run:
You’ll see the following output:
If the output says Installer corrupt, you’ll need to download the installation script again and double check that you’re using the correct hash. Then, repeat the verification process. When you have a verified installer, you can continue.
To install composer globally, use the following command which will download and install Composer as a system-wide command named composer, under /usr/local/bin:
You’ll see output similar to this:
OutputAll settings correct for using Composer
Downloading...
Composer (version 1.10.5) successfully installed to: /usr/local/bin/composer
Use it: php /usr/local/bin/composer
To test your installation, run:
Then install the mysql-server package:
This will install MySQL, but will not prompt you to set a password or make any other configuration changes. Because this leaves your installation of MySQL insecure, we will address this next.
Step 2 — Configuring MySQL
For fresh installations of MySQL, you’ll want to run the DBMS’s included security script. This script changes some of the less secure default options for things like remote root logins and sample users.
Run the security script with sudo:
This will take you through a series of prompts where you can make some changes to your MySQL installation’s security options. The first prompt will ask whether you’d like to set up the Validate Password Plugin, which can be used to test the password strength of new MySQL users before deeming them valid.
If you elect to set up the Validate Password Plugin, any MySQL user you create that authenticates with a password will be required to have a password that satisfies the policy you select. The strongest policy level — which you can select by entering 2 — will require passwords to be at least eight characters long and include a mix of uppercase, lowercase, numeric, and special characters:
OutputSecuring the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?
Press y|Y for Yes, any other key for No: Y
There are three levels of password validation policy:
LOW Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG:
2
Regardless of whether you choose to set up the Validate Password Plugin, the next prompt will be to set a password for the MySQL root user. Enter and then confirm a secure password of your choice:
OutputPlease set the password for root here.
New password:
Re-enter new password:
Note that even though you’ve set a password for the root MySQL user, this user is not currently configured to authenticate with a password when connecting to the MySQL shell.
If you used the Validate Password Plugin, you’ll receive feedback on the strength of your new password. Then the script will ask if you want to continue with the password you just entered or if you want to enter a new one. Assuming you’re satisfied with the strength of the password you just entered, enter Y to continue the script:
OutputEstimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : Y
From there, you can press Y and then ENTER to accept the defaults for all the subsequent questions. This will remove some anonymous users and the test database, disable remote root logins, and load these new rules so that MySQL immediately respects the changes you have made.
Once the script completes, your MySQL installation will be secured. You can now move on to creating a dedicated database user with the MySQL client.
Step 3 — Creating a Dedicated MySQL User and Granting Privileges
Upon installation, MySQL creates a root user account which you can use to manage your database. This user has full privileges over the MySQL server, meaning it has complete control over every database, table, user, and so on. Because of this, it’s best to avoid using this account outside of administrative functions. This step outlines how to use the root MySQL user to create a new user account and grant it privileges.
In Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. This plugin requires that the name of the operating system user that invokes the MySQL client matches the name of the MySQL user specified in the command, so you must invoke mysql with sudo privileges to gain access to the root MySQL user:
Note: If you installed MySQL with another tutorial and enabled password authentication for root, you will need to use a different command to access the MySQL shell. The following will run your MySQL client with regular user privileges, and you will only gain administrator privileges within the database by authenticating:
Once you have access to the MySQL prompt, you can create a new user with a CREATE USER statement. These follow this general syntax:
After CREATE USER, you specify a username. This is immediately followed by an @ sign and then the hostname from which this user will connect. If you only plan to access this user locally from your Ubuntu server, you can specify localhost. Wrapping both the username and host in single quotes isn’t always necessary, but doing so can help to prevent errors.
You have several options when it comes to choosing your user’s authentication plugin. The auth_socket plugin mentioned previously can be convenient, as it provides strong security without requiring valid users to enter a password to access the database. But it also prevents remote connections, which can complicate things when external programs need to interact with MySQL.
As an alternative, you can leave out the WITH authentication plugin portion of the syntax entirely to have the user authenticate with MySQL’s default plugin, caching_sha2_password. The MySQL documentation recommends this plugin for users who want to log in with a password due to its strong security features.
Run the following command to create a user that authenticates with caching_sha2_password. Be sure to change sammy to your preferred username and password to a strong password of your choosing:
Note: There is a known issue with some versions of PHP that causes problems with caching_sha2_password. If you plan to use this database with a PHP application — phpMyAdmin, for example — you may want to create a user that will authenticate with the older, though still secure, mysql_native_password plugin instead:
FOR PHP !!!!!!!!!!!!!!!!!!!!!!! Need to create user identeified with mysql_native_password
If you aren’t sure, you can always create a user that authenticates with caching_sha2_plugin and then ALTER it later on with this command:
After creating your new user, you can grant them the appropriate privileges. The general syntax for granting user privileges is as follows:
The PRIVILEGE value in this example syntax defines what actions the user is allowed to perform on the specified database and table. You can grant multiple privileges to the same user in one command by separating each with a comma. You can also grant a user privileges globally by entering asterisks (*) in place of the database and table names. In SQL, asterisks are special characters used to represent “all” databases or tables.
To illustrate, the following command grants a user global privileges to CREATE, ALTER, and DROP databases, tables, and users, as well as the power to INSERT, UPDATE, and DELETE data from any table on the server. It also grants the user the ability to query data with SELECT, create foreign keys with the REFERENCES keyword, and perform FLUSH operations with the RELOAD privilege. However, you should only grant users the permissions they need, so feel free to adjust your own user’s privileges as necessary.
You can find the full list of available privileges in the official MySQL documentation.
Run this GRANT statement, replacing sammy with your own MySQL user’s name, to grant these privileges to your user:
mysql -ubeer -pbeer -h192.168.1.100 ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.100' (111)

If the package in the repositories suits your needs, this is all you need to do to get set up with Node.js. In most cases, you’ll also want to install npm, the Node.js package manager. You can do this by typing:
This will allow you to install modules and packages to use with Node.js.
Because of a conflict with another package, the executable from the Ubuntu repositories is called nodejs instead of node. Keep this in mind as you are running software.
To check which version of Node.js you have installed after these initial steps, type:
$ sudo npm install vue@next
Getting started with Vue.js
To get started with Vue.js, to create a project using Vue CLI using the following command.
After running this command, you will be asked to choose a preset.
You can either go with the default or add custom features. You can also use the GUI method to create a Vue project by using the following command.
