Setup PHP FPM

Run the following commands to install PHP FPM:

apt-get install php5-fpm php5-cli php-apc php5-suhosin php5-curl php5-gd php5-intl php5-mcrypt php-gettext php5-mysql php5-sqlite

After the installation completed, we’re going to customize it. But first, let’s backup the config files.

mkdir /root/backup
mkdir /root/backup/etc
mkdir /root/backup/etc/php5
mkdir /root/backup/etc/php5/conf.d
mkdir /root/backup/etc/php5/fpm
mkdir /root/backup/etc/php5/fpm/pool.d
cp /etc/php5/conf.d/apc.ini /root/backup/etc/php5/conf.d
cp /etc/php5/fpm/php.ini /root/backup/etc/php5/fpm
cp /etc/php5/fpm/pool.d/www.conf /root/backup/etc/php5/fpm/pool.d

Now let’s modify /etc/php5/conf.d/apc.ini. Replace its content with:

[APC]
extension=apc.so
apc.enabled=1
apc.shm_segments=1
apc.shm_size=16
apc.ttl=7200
apc.user_ttl=7200
apc.num_files_hint=1024
apc.mmap_file_mask=/tmp/apc.XXXXXX
apc.max_file_size = 1M
apc.post_max_size = 1000M
apc.upload_max_filesize = 1000M
apc.enable_cli=0
apc.rfc1867=0

Next, let’s modify /etc/php5/fpm/php.ini. Append the following text:

[apc]
apc.write_lock = 1
apc.slam_defense = 0

Lastly, let’s modify /etc/php5/fpm/pool.d/www.conf. Match the content with below configuration:

user = nginx
group = nginx
listen = /dev/shm/php-fpm-www.sock
listen.owner = nginx
listen.group = nginx
listen.mode = 0666

Let’s now restart the service

service php5-fpm restart
