Laravel‘s PHP framework installation is not a big deal. You can simply follow the step by step guide in this article for your CentOS 7 or Ubuntu 15 server.

1) Server Requirements

Laravel depends upon a number of prerequisites that must be setup before installing it. Those prerequisites includes some basic tuning parameter of server like your system update, sudo rights and installation of required packages.

Once you are connected to your server make sure to configure the fully qualified domain name then run the commands below to enable EPEL Repo and update your server.

CentOS-7

# yum install epel-release

# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

# yum update

Ubuntu

# apt-get install python-software-properties
# add-apt-repository ppa:ondrej/php5

# apt-get update

# apt-get install -y php5 mcrypt php5-mcrypt php5-gd

2) Firewall Setup

System Firewall and SELinux setup is an important part regarding the security of your applications in production. You can make firewall off if you are working on test server and keep SELinux to permissive mode using the below command, so that you installing setup won‘t be affected by it.

# setenforce 0

3) Apache, MariaDB, PHP Setup

Laravel installation requires a complete LAMP stack with OpenSSL, PDO, Mbstring and Tokenizer PHP Extensions. If you are already running LAMP server then you can skip this step to move on and just make sure that the required PHP extensions are installed.

To install AMP stack you can use the below commands on your respective server.

CentOS

# yum install httpd mariadb-server php56w php56w-mysql php56w-mcrypt php56w-dom php56w-mbstring

To start and enable Apache web and MySQL/Mariadb services at bootup on CentOS 7 , we will use below commands.

mysqld改成了systemctl start mariadb.service

# systemctl start httpd
# systemctl enable httpd

#systemctl start mysqld
#systemctl enable mysqld

After starting MariaDB service, we will configure its secured password with below command.

#mysql_secure_installation

Ubuntu

# apt-get install mysql-server apache2 libapache2-mod-php5 php5-mysql

4) Install Composer

Now we are going to install composer that is one of the most important requirement before starting the Laravel installation that helps in installing Laravel‘s dependencies.

CentOS/Ubuntu
Run the below commands to setup ‘composer‘ in CentOS/Ubuntu.

# curl -sS https://getcomposer.org/installer | php
# mv composer.phar /usr/local/bin/composer
# chmod +x /usr/local/bin/composer

composer installation

5) Installing Laravel

Laravel‘s installation package can be downloaded from github using the command below.

# wget https://github.com/laravel/laravel/archive/develop.zip

To extract the archived package and move into the document root directory use below commands.

# unzip develop.zip

# mv laravel-develop /var/www/

Now use the following compose command that will install all required dependencies for Laravel within its directory.

# cd /var/www/laravel-develop/
# composer install

compose laravel

6) Key Encryption

For encrypter service, we will be generating a 32 digit encryption key using the command below.

.env.example 文件改成.env文件

# php artisan key:generate

Application key [Lf54qK56s3qDh0ywgf9JdRxO2N0oV9qI] set successfully

Now put this key into the ‘app.php‘ file as shown below.

# vim /var/www/laravel-develop/config/app.php

Key encryption

7) Virtua Host and Ownership

After composer installation assign the permissions and apache user ownership to the document root directory as shown.

安装在/var/www/html/blog目录下的laravel对blog目录进行对应的操作然后打开链接/blog/public一样显示安装laravel成功

# chmod 775 /var/www/laravel-develop/app/storage

# chown -R apache:apache /var/www/laravel-develop

Open the default configuration file of apache web server using any editor to add the following lines at the end file for new virtual host entry.

把原来的/var/www/html 改成/var/www/laravel-develop/public

# vim /etc/httpd/conf/httpd.conf

ServerName laravel-develop
DocumentRoot /var/www/laravel/public

start Directory /var/www/laravel
AllowOverride All
Directory close

Now the time is to restart apache web server services as shown below and then open your web browser to check your localhost page.

CentOS

# systemctl restart httpd

Ubuntu

# service apache2 restart

8) Laravel 5 Web Access
