AWS: Install Apache, PHP, APC, & MySQL on Amazon EC2 with Amazon Linux AMI

The following guide is a step by step guide on installing and configuring Apache, PHP (with APC) & MySQL (LAMP Stack) on an Amazon EC2 instance running Amazon Linux AMI. The procedure has been tested on Amazon Linux AMI, but should also apply in general to Fedora/Red Hat/CentOS distributions.

1. Install Linux updates, set time zones, followed by GCC and Make

sudo yum -y update
sudo ln -sf /usr/share/zoneinfo/Singapore \
      /etc/localtime
sudo yum install -y gcc make

2. Install PHP and PHP extensions

sudo yum install -y php
sudo yum install -y php-devel php-mysql php-pdo
sudo yum install -y php-pear php-mbstring

sudo pear install Log
sudo yum install -y pcre-devel

3. Install Apache httpd

sudo yum -y install httpd
sudo service httpd start

4. Install MySQL

sudo yum -y install mysql-server mysql
sudo service mysqld start

5. Install PHP APC module

sudo yum -y install httpd-devel
sudo pecl install apc-beta
echo "extension=apc.so" | sudo tee /etc/php.d/apc.ini

Or Simply:

sudo yum install -y php-pecl-apc

6. MySQL Configuration

sudo vi /etc/my.cnf

[mysqld]
...
skip-external-locking
long_query_time=1
slow_query_log
slow_query_log_file=/var/log/log-slow-queries.log
log-bin=mysql-bin
server-id= 1
...

[mysqld_safe]
...
myisam_recover_options
...

[mysqld]
...
key_buffer_size = 128M
max_allowed_packet = 3M
table_open_cache = 64
read_buffer_size = 2M
read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 16M
thread_cache_size = 8
query_cache_size= 32M
thread_concurrency = 8
innodb_buffer_pool_size = 128M
innodb_log_file_size = 32M
innodb_additional_mem_pool_size = 8M
innodb_log_buffer_size = 4M
...

Log Slow Queries:

sudo touch /var/log/log-slow-queries.log
sudo chown mysql.mysql /var/log/log-slow-queries.log

sudo /sbin/chkconfig --levels 235 mysqld on
sudo service mysqld start

7. PHP Configuration Changes in php.ini

sudo nano /etc/php.ini

expose_php = Off
memory_limit = 128M
date.timezone = America/Indianapolis

Note: Location of error file

/var/log/httpd/error.log

8. Auto Start Apache in EC2 Amazon Linux

sudo /sbin/chkconfig --levels 235 httpd on
sudo service httpd start
