LAMP

Available in Classic

LAMP is an open source software stack service for web applications named after the first letters of Linux, Apache, MySQL, and PHP. It is automatically configured on NAVER Cloud Platform's Compute infrastructure service and can be instantly put into service through a configuration process with only a few steps.
The advantages of using LAMP are as follows:

• You can use a stable web service development platform utilizing the infrastructure services of NAVER Cloud Platform.
• You can select a server image and specifications to automatically install and use the LAMP stack service.

Creating and accessing server

The method for creating and accessing the server is the same as creating a regular server on NAVER Cloud Platform. The following are detailed procedures and reference guides:

Check LAMP installation

When the server is created, the LAMP components are automatically installed, so you can use the service immediately. Check if the components are installed successfully through the following methods:

Access web

Access the LAMP service through the web, and then check if it is installed successfully. The access URL is http://{public ip address}. If the index page of NAVER Cloud Platform's LAMP is run upon accessing, it is successfully installed.

Check installation directory

Access the server through the terminal program, and then call installation directory and logs to check if it is installed successfully.

• Check LAMP component installation directory information

# ls /root/lamp
conf  lamp_info.sh  lamp_restart.sh  uninstall_lamp_centos.sh

• Check LAMP web root directory information

# ls /ncp/data/www
index.html ncp ncp.jquery.js

• Check LAMP installation log

# cat /var/log/lamp/lamp_install.log

Check PHP information

Create the PHP information file and check if the PHP and PHP modules are installed successfully.

1. Enter the following command to create the PHP information file.

   echo "<?php phpinfo(); ?>" > /ncp/data/www/phpinfo.php
   

   Note

   When a permission error occurs when running commands, run Change Linux permissions.

2. Enter http://{public ip address}/phpinfo.php in the web's address window and run it.

3. View relative information on the LAMP's PHP information page displayed on the web browser.

4. If you have checked all the information, delete the PHP information file for security reasons. Enter the following commands to delete files.

   rm /ncp/data/www/phpinfo.php
   

Manage LAMP service

While you use the service, you can stop running or restart the components manually, or check the components' properties and process.

Stop/run LAMP components

When you need to stop or run components manually, enter the following commands:

• Stop and run all LAMP components

[root@lamp ~]# LAMP_HOME=/root/lamp
[root@lamp ~]# $LAMP_HOME/lamp_restart.sh

Change MySQL root password

When you install LAMP, MySQL DB's root password is set as your host name.
Before you use it, change the password to protect your security.

Enter the following commands to change the password.

[root@lamp ~]# mysql_secure_installation


NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
