2. Install and Configure Apache Service

Apache is a Web server software. This step describes how to install and configure Apache on an ECS instance.

1. On the right side of the lab page, click ICON Icon to switch to Web Terminal.

Enter the username and password for logging on to the ECS instance.

2. Install Apache.

2.1 run the following command to install the Apache service and its extension package.

This experiment is based on the CentOS Operating System. If you are using another operating system, please refer to this link for installation.

yum -y install httpd mod_ssl mod_perl mod_auth_mysql

2.2 Run the following command to check whether Apache is installed successfully.

httpd -v

The following result indicates that you have successfully installed Apache.

2.3 Run the following command to start the Apache service.

systemctl start httpd.service

3. In the address bar of your local browser, visit <http:// the public IP address of the ECS instance>.

Note: You need to replace the public IP address of the ECS instance with the public IP address of the ECS instance. You can view the public IP address of the ECS instance in the ECS console.

If the returned page is shown in the following figure, the Apache service is started successfully.

3. Install MariaDB Database

Because WordPress is used to build a cloud blog, you need to use the MySQL database to store data. This step will guide you to install an open source MariaDB for MySQL (MariaDB compatible with MySQL) on your ECS instance and create a blog database.

1. In the function bar on the right side of the lab, click ICON Icon to switch to Web Terminal.

2. Run the following command to install the MariaDB Server.

yum install -y mariadb-server

Return the following command to indicate that you have installed MariaDB Server.

3. Run the following command to start the MariaDB Server.

systemctl start mariadb

4. Run the following command to view the running status of the MariaDB Server.

systemctl status mariadb

The returned result is as follows. When you see active (running), the MariaDB Server is started successfully.

5. Run the following command to set the initial password for the database root user.

mysqladmin -u root -p password

The following result is returned. Since this is the first time you set the database Password, you can press Enter when the Enter Password prompt appears.

Return the following result, enter the new password as 123456789, and enter 123456789 again after entering. (The entered password will not be displayed. This is normal and there is no error.)

6. Run the following command to connect to the database.

mysql -u root -p

The following result is returned. When the Enter password prompt appears, Enter the root user password 123456789 to sign in to the database. (The password entered will not be displayed, this is normal, there is no error)

7. Run the following command to create WordPress database.

create database wordpress;

8. Run the following command to view the database.

show databases;

The following figure shows the WordPress database you created.

9. Run the following command to exit the database.

exit;

4. Install PHP

PHP is a widely used common open source scripting language, suitable for Web site development, and can be embedded in HTML. This step describes how to install and configure the PHP service on an ECS instance.

1. Run the following command to install PHP.

yum -y install php php-mysql gd php-gd gd-devel php-xml php-common php-mbstring php-ldap php-pear php-xmlrpc php-imap

The following result indicates that you have installed PHP.

2. Run the following command to create a PHP test page.

echo "<?php phpinfo(); ?>" > /var/www/html/phpinfo.php

3. Run the following command to restart the Apache service.

systemctl restart httpd

4. In the address bar of your browser, visit http://<ECS public address>/phpinfo.php.

Note: You need to replace <ECS public IP address> with the ECS public IP address.

Return to the following page, indicating that the PHP language environment is installed successfully.

5. Install and Configure WordPress

This step describes how to install and configure WordPress on an ECS instance.

# Modify the path.
ln -snf /etc/wordpress/wp-config.php wp-config.php
# Check out the modified directory structure.
ll

3.2 Run the following command to move the wordpress file to the Apache root directory.

# Create a wp-blog folder under Apache's root directory /var/www/html.
mkdir /var/www/html/wp-blog
mv * /var/www/html/wp-blog/

3.3 Run the following command to modify the wp-config.php configuration file.

sed -i 's/database_name_here/wordpress/' /var/www/html/wp-blog/wp-config.php
sed -i 's/username_here/root/' /var/www/html/wp-blog/wp-config.php
sed -i 's/password_here/123456789/' /var/www/html/wp-blog/wp-config.php

cat -n /var/www/html/wp-blog/wp-config.php

The following results are returned. You can see that the configuration file information has been modified.

3.5 Run the following command to restart the Apache service.

systemctl restart httpd

6. Test WordPress

After completing all the preceding steps, you can test the Cloud blog based on ECS.

1. In the address bar of the browser, visit http://<ECS public address>/wp-blog/wp-admin/install.php.

Note: You need to replace <ECS public IP address> with the ECS public IP address. For example, http:// 192.168.0.1/wp-blog/wp-admin/install.php
