Salah satu solusi yang paling tepat untuk mengurangi memory footprint pada web server Apache adalah dengan menggunakan PHP-FPM.
Sebelumnya update terlebih dahulu:
yum update
Lalu tambahkan repo berikut, pilih sesuai OS:
//CentOS 6 32 bit
rpm -ivh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -ivh http://www.city-fan.org/ftp/contrib/yum-repo/rhel6/i386/city-fan.org-release-1-13.rhel6.noarch.rpm
//CentOS 64 bit
rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -ivh http://www.city-fan.org/ftp/contrib/yum-repo/rhel6/x86_64/city-fan.org-release-1-13.rhel6.noarch.rpm
Lalu enable remi-release:
vi /etc/yum.repos.d/remi.repo
Enable remi repo secara default:
[remi]
name=Les RPM de remi pour Enterprise Linux 6 - $basearch
#baseurl=http://rpms.famillecollet.com/enterprise/6/remi/$basearch/
mirrorlist=http://rpms.famillecollet.com/enterprise/6/remi/mirror
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
Kemudian install Apache, PHP-FPM. Buat supaya berjalan otomatis ketika reboot:
yum install httpd php-fpm php-xml
service httpd start
chkconfig httpd on
chkconfig php-fpm on
Install mod_fastcgi:
yum install mod_fastcgi
Disable mod_php:
mv /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php.conf.bak
Menggunakan Worker dibandingkan dengan Prefork dengan mengedit /etc/sysconfig/httpd dan hilangkan tanda pagar menjadi seperti berikut:
vi /etc/sysconfig/httpd
HTTPD=/usr/sbin/httpd.worker
Konfigurasi FastCGI dengan mendisable FastCgiWrapper pada fastcgi.conf di folder /etc/httpd/conf.d:
vi /etc/httpd/conf.d/fastcgi.conf
# wrap all fastcgi script calls in suexec
FastCgiWrapper Off
Tambahkan kode berikut di fastcgi.conf:
<IfModule mod_fastcgi.c>
DirectoryIndex index.html index.shtml index.cgi index.php
AddHandler php-fastcgi .php
Action php-fastcgi /php-fcgi
Alias /php-fcgi /var/run/php-fcgi
FastCgiExternalServer /var/run/php-fcgi -host 127.0.0.1:9000 -pass-header Authorization -idle-timeout 120
</IfModule>
Konfigurasi /etc/php-fpm.d/www.conf:
vi /etc/php-fpm.d/www.conf
listen = 127.0.0.1:9000
listen.owner = apache
listen.group = apache
listen.mode = 0660
Start PHP-FPM:
service php-fpm start
Buat file info.php di /var/www/html/info.php, tambahkan konten berikut:
vi /var/www/html/info.php
<?php
phpinfo();
?>
Restart Apache dan PHP-FPM:
service httpd restart
service php-fpm restart
Sekarang coba kita kunjungi http://alamatIP/info.php. Server API harusnya sudah tertulis FPM-FastCGI.
Sekarang kita install MySQL server.
yum install mysql-server phpmyadmin
service mysqld start
chkconfig mysqld on
Lalu konfigurasi MySQL server supaya aman:
mysql_secure_installation
Konfigurasi phpmyadmin:
vi /etc/httpd/conf.d/phpMyAdmin.conf
# phpMyAdmin - Web based MySQL browser written in php
#
# Allows only localhost by default
#
# But allowing phpMyAdmin to anyone other than localhost should be considered
# dangerous unless properly secured by SSL
Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin
<Directory /usr/share/phpMyAdmin/>
AddDefaultCharset UTF-8
<IfModule mod_authz_core.c>
# Apache 2.4
Require local
</IfModule>
<IfModule !mod_authz_core.c>
# Apache 2.2
# Order Deny,Allow
# Deny from All
# Allow from 127.0.0.1
# Allow from ::1
</IfModule>
</Directory>
Ubah authentication ke http dan restart Apache:
vi /etc/phpMyAdmin/config.inc.php
$cfg['Servers'][$i]['auth_type'] = 'http';
service httpd restart
Alamat phpmyadmin bisa dikunjungi di http://alamatIP/phpmyadmin.
Untuk menggunakan socket pada PHP-FPM, ubah pada /etc/php-fpm.d/www.conf:
vi /etc/php-fpm.d/www.conf
listen = /var/run/php-fpm.sock
Serta pada /etc/httpd/conf.d/fastcgi.conf:
vi /etc/httpd/conf.d/fastcgi.conf
FastCgiExternalServer /var/run/php-fcgi -socket /var/run/php-fpm.sock -pass-header Authorization -idle-timeout 120
