Ubuntu系统AWS AMI搭建LAMP栈：MySQL服务启动失败求助

Hey there, let's work through this MySQL service issue you're hitting on your Ubuntu AWS AMI. The key thing to note here is that the AWS LAMP tutorial you're referencing is tailored for Amazon Linux, not Ubuntu—they use different package names and service management tools, which is why those service commands aren't working.

Step 1: Confirm MySQL Server is actually installed #

First, let's check if you even have the MySQL database server installed. The mysqlnd output you shared is just a PHP extension that lets PHP talk to MySQL—it's not the database service itself. Run this command to verify:

sudo apt list --installed | grep mysql-server

If you don't see any results for mysql-server, that's the problem! Install it with:

sudo apt update && sudo apt install mysql-server -y

Step 2: Use the correct service command for Ubuntu #

Ubuntu uses systemctl (instead of the older service syntax for some services) and the service name is mysql, not mysqld. To start the service:

sudo systemctl start mysql

Step 3: Verify the service is running #

Check if MySQL is up and healthy with:

sudo systemctl status mysql

You should see a "active (running)" status if everything worked.

Step 4: Set MySQL to start on boot (optional but recommended) #

To make sure MySQL starts automatically when your instance reboots:

sudo systemctl enable mysql

Quick note on mysqlnd #

Your php -i | grep mysqlnd output looks totally normal—this is just the PHP driver that handles communication between PHP and MySQL. Once the MySQL service is running, this extension will work as expected to connect your PHP apps to the database.
