# Install Valet Linux on Ubuntu from scratch ![valet.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1609624764836/-YNhFCh5e.png) In this post, we will set our development environment with PHP, Laravel, MariaDB/MySQL, and Valet Linux; yeah, the exclusive macOS development tool working on Linux ;D. ### Install MariaDB ![mariadb.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1609625038966/skWB793sK.png) To install MariaDB, open the terminal, and type the following command: ```bash sudo apt install mariadb-server mariadb-client ``` After the installation concludes, test the following commands in that specific order to check if the installation was successful: ```bash sudo systemctl stop mariadb.service sudo systemctl start mariadb.service sudo systemctl enable mariadb.service ``` After verifying the installation was successful, we need to run the `mysql_secure_installation`, to set MariaDB correctly in our development environment: ```bash sudo mysql_secure_installation ``` After you execute the command, please answer the following questions: - Enter current password for root (enter for none): **Just press enter** - Set root password? [Y/n]: **Y** - New password: **Write a secure password** - Re-enter new password: **Repeat the password** - Remove anonymous users? [Y/n]: **Y** - Disallow root login remotely? [Y/n]: **Y** - Remove test database and access to it? [Y/n]: **Y** - Reload privilege tables now? [Y/n]: **Y** Restart MariaDB's service: ```bash sudo systemctl restart mariadb.service ``` Then, access to MariaDB through the terminal: ```bash sudo mariadb -u root -p ``` Or ```bash sudo mysql -u root -p ``` **Remember that MariaDB is fully compatible with MySQL ;).** We need to write the password that we defined in the `mysql_secure_installation` process in the following SQL statement. This also helps to access MariaDB without **sudo** on the terminal: ```SQL GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY "your_password"; ``` Now exit from MariaDB by pressing: **Ctrl+C** on the terminal. ### Install PHP on Linux ![php.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1609625575852/t9O1pZb5B.png) This is very straight; forward we only need to run the following command: ```bash sudo apt install php libapache2-mod-php php-common php-mbstring php-xmlrpc php-soap php-gd php-xml php-mysql php-cli php-mcrypt php-zip php-curl php-sqlite3 php-pgsql ``` And then open **php.ini** file to make some adjustments: ```bash sudo nano /etc/php/7.X/apache2/php.ini ``` Modify the following variables: ```bash memory_limit = 256M upload_max_filesize = 64M cgi.fix_pathinfo=0 ``` We save the changes by pressing `Ctrl+O` and exit with `Ctrl+X`. ### Install Laravel on Linux ![laravel.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1609625439070/v0Vw6xZ_O.png) We need `composer` installed in our system to do that, we can install it with: ```bash sudo apt install composer ``` And now install Laravel: ```bash composer global require laravel/installer ``` Now we need to add Laravel in our $PATH variable, to make "laravel" a recognizable command: ```bash sudo nano .bashrc ``` If you are using **zsh**: ```bash sudo nano .zshrc ``` Scroll down to the last line of the file and add the following: ```bash export PATH="$HOME/.config/composer/vendor/bin:$PATH" ``` We save the changes by pressing `Ctrl+O` and exit with `Ctrl+X`. And to force our shell to read the changes, execute: ```bash source .bashrc ``` If you are using **zsh**: ```bash source .zshrc ``` Now we can create a Laravel app: ```bash laravel new laravel-app ``` If you want to use Laravel 7, try with the following commands and ensure that the PHP version you installed is PHP 7 and not PHP 8: ```bash composer create-project laravel/laravel=^7 laravel-app --prefer-dist ``` If it does not work try replacing the **^** with **>**: ```bash composer create-project laravel/laravel=>7 laravel-app --prefer-dist ``` It should create a Laravel app without problems. ### Install Valet Linux ![valet.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1609624764836/-YNhFCh5e.png) Finally, execute: ```bash composer global require cpriego/valet-linux ``` If it throws an error, please execute: ```bash sudo apt install php-curl ``` Try again and now it should work. Now execute the installation process: ```bash valet install ``` This also could throw an error, if that's the case, please force the shell to read the changes as we did before: ```bash source .bashrc ``` If you are using **zsh**: ```bash sudo nano .zshrc ``` We need to ensure that we update our $PATH environment variable correctly on the previous steps. Now `valet` should throw an error about missing dependencies, to solve that we simply run: ```bash sudo apt-get install network-manager libnss3-tools jq xsel ``` Now it should install valet correctly: ```bash valet install ``` But if you have another error related with `nginx`, you need to stop the service that is running in the same port as `nginx`, if it's `apache` who is provoking this problem you can simply stop the apache's service: ```bash sudo systemctl stop apache2.service ``` And try again: ```bash valet install ``` To verify everything is ok, run: ```bash ping valet.test ``` And after a few seconds it should say something like this: ```bash X packets transmited, X received... ``` If that's the case, congrats! you successfully installed Valet Linux! Now we need to set the directory where we are going to create Laravel or PHP projects: ```bash cd directory/where/you/are/going/to/work ``` And execute: ```bash valet park ``` Now create a folder called: `phpinfo`, inside the create a file called `index.php` and in the file, we can write something to check its working: ```php
