Manually Deploying LAMP (CentOS 7.8 PHP 7.0)

Overview

LAMP is a web application platform consisting of Linux, Apache, MySQL, and PHP.

The best practices for Huawei Cloud ECS guide you through the deployment of LAMP on a Linux ECS. The CentOS 7.8 64bit OS is used as an example in this section.

Prerequisites

The ECS has an EIP bound.

The rule listed in the following table has been added to the security group which the target ECS belongs to. For details, see Adding a Security Group Rule.

**Table 1** Security group rule
Direction	Priority	Action	Type	Protocol & Port	Source Address
Inbound	1	Allow	IPv4	TCP: 80	0.0.0.0/0

The image source has been updated to a Huawei Cloud image source. For details, see How Can I Use an Automated Tool to Configure a Huawei Cloud Image Source (x86_64 and Arm)? This facilitates obtaining and updating the system and software.

Resource Planning

Table 2 lists the resource configuration and software versions used in this practice. The commands and parameters may vary according to the hardware specifications or software versions you would use.

**Table 2** Resources and costs
Resource	Description	Cost
ECS	Billing mode: pay-per-use AZ: AZ1 Flavor: c7.large.2 Image: CentOS 7.8 64bit System disk: 40 GiB EIP: Auto assign EIP type: Dynamic BGP Billed by: Traffic Bandwidth: 5 Mbit/s	The following resources generate costs: ECSs EVS disks EIPs For billing details, see Billing Modes.
Apache	An open-source web server	Free
MySQL	An open-source relational database software Download URL: http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm	Free
PHP	An open-source software used for web development Download URL: https://mirror.webtatic.com/yum/el7/epel-release.rpm https://mirror.webtatic.com/yum/el7/webtatic-release.rpm	Free

Procedure

Install Apache.
1. Log in to the ECS.
2. Run the following commands as user root to update the software package and install Apache:
  yum -y update
  
  yum -y install httpd
3. Run the following command to check the version of the installed Apache:
  httpd -v
  
  Information similar to the following is displayed:
```
Server version: Apache/2.4.6 (CentOS)
Server built:  May 30 2023 14:01:11
```
4. Run the following commands in sequence to start Apache and enable it to start automatically upon ECS startup:
  systemctl start httpd
  
  systemctl enable httpd
5. Enter http://Server IP address in the address bar of the browser to access Apache. If the following page is displayed, Apache has been installed.

Install MySQL.

Run the following commands in sequence to install MySQL:
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

yum -y install mysql57-community-release-el7-10.noarch.rpm

yum -y install mysql-community-server --nogpgcheck
Run the following command to check the version of the installed MySQL:
mysql -V

Information similar to the following is displayed:
```
mysql  Ver 14.14 Distrib 5.7.44, for Linux (x86_64) using  EditLine wrapper
```
Run the following commands in sequence to start MySQL and enable it to start automatically upon ECS startup:
systemctl start mysqld

systemctl enable mysqld

Run the following command to check the MySQL status:

systemctl status mysqld.service

[root@ecs-adc3 ~]# systemctl status mysqld.service
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
   Active: active (running) since Tue 2023-10-31 19:33:40 CST; 36s ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
 Main PID: 7916 (mysqld)
   CGroup: /system.slice/mysqld.service
           └─7916 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid

Aug 16 19:33:35 ecs-adc3 systemd[1]: Starting MySQL Server...
Aug 16 19:33:40 ecs-adc3 systemd[1]: Started MySQL Server.

Run the following commands to obtain the root user's password that is automatically set during MySQL installation:
grep 'temporary password' /var/log/mysqld.log
Information similar to the following is displayed:
```
2023-10-31T11:53:08.691748Z 1 [Note] A temporary password is generated for root@localhost: 2YY?3uHUA?Ys
```

Run the following command and follow the prompts to harden MySQL:

mysql_secure_installation

Securing the MySQL server deployment.

Enter password for user root: #Enter the obtained password of user root.
The existing password for the user account root has expired. Please set a new password.

New password: #Enter a new password of user root.

Re-enter new password: #Enter the new password again.
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration of the plugin.
Using existing password for root.

Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : N #Press N.

... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y #Press Y to remove anonymous users.
Success.

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y #Press Y to disallow remote logins of user root.
Success.

By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y #Press Y to delete the test database and remove access to it.
- Dropping test database...
Success.

- Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y #Press Y to reload privilege tables.
Success.

All done!
