How to deploy php to cloud server

With the rise of cloud computing, more and more people are beginning to deploy their applications to cloud servers. As a powerful web development language, PHP is also widely used on cloud servers.

This article will introduce how to deploy PHP on a cloud server, covering the following content:

1. Select the cloud server platform
2. Configure the cloud server environment
3. Install PHP
4. Deploy applications
5. Frequently asked questions and solutions
6. Select a cloud server platform

Choose a cloud server platform that suits you, you can Greatly affects the success and efficiency of deployment. Currently, the more popular cloud server platforms on the market include Alibaba Cloud, Tencent Cloud, AWS, etc. Each of these platforms has its own features, pros and cons, and you need to choose one based on your own needs.

2. Configuring the cloud server environment

Deploying PHP applications requires creating a Web server environment on the cloud server, including installing Web server, PHP, database and other components. For the specific installation process, please refer to the documentation of the cloud server platform. Here we take Alibaba Cloud as an example.

2.1 Install the Web server

We take the CentOS7 system on Alibaba Cloud ECS as an example to install the Apache Web server.

Open the terminal and log in as the root user:

$ ssh root@your_ip

Enter the password. After entering the root user, update the system:

yum update -y

Install Apache:

yum install httpd -y

After the installation is complete, start Apache:

systemctl start httpd

Set Apache to start automatically at boot:

systemctl enable httpd

Enter your cloud server IP address in the browser. If you can see the Apache test page, the installation is successful.

2.2 Install PHP

To install PHP, you need to use the yum source. Now start the configuration:

yum install epel-release -y

Next, install PHP and PHP extensions:

yum install php php-mysql -y

After the installation is complete, test whether PHP can work. Create a PHP file:

vim /var/www/html/info.php

Append the following content to the file:

phpinfo ();
?>

Save and exit. Enter your cloud server IP address/filename.php in the browser. If you can see the PHP information page, it means that PHP is installed successfully.

2.3 Install the database

If the application needs to use a database, the corresponding database needs to be installed. Here is MySQL as an example.

Install MySQL:

yum install mysql-server -y

Start MySQL:

systemctl start mysqld

Set MySQL to boot automatically Start:

systemctl enable mysqld

Set password for MySQL:

mysql_secure_installation

Just follow the prompts.

3. Deploy the application

You need to pay attention to the following points when deploying the application:

3.1 Copy the application code to the root directory of the Web server.

3.2 Configure the application configuration file, including database connection information, etc.

3.3 Set the permissions of the application to ensure that the PHP process has sufficient permissions to read and write the application's files.

4. Frequently asked questions and solutions

4.1 Unable to access the PHP page

If you enter the IP address/filename.php in the browser, you cannot access it PHP page, you can try to check the following aspects:

1) Check whether PHP has been installed successfully and whether Apache has started normally.

2) Make sure the permissions of the PHP file are correct. It is recommended to set index.php to 644 permissions.

3) Check whether the PHP Apache module is installed. If not, you need to enable it manually.

4.2 Unable to connect to the database

If the program and the database are on the same machine, you can use localhost as the server address of the database.

If the program and database are on different machines, you need to ensure that the port of the database server is open. In addition, you need to set security group rules for the database server to allow the IP address of the cloud server to access the database server.

If none of the above methods solve the problem, you can check whether the information such as the database connection string is correct, or check whether there are conflicts in the system configuration such as the firewall.
