Auto resize partition will expand it same block device size

Install Haproxy from source on Debian 7

apt-get install build-essential make g++ libssl-dev

tar xvf haproxy-1.6.5.tar.gz

cd haproxy-1.6.5

make TARGET=linux2628  USE_OPENSSL=yes USE_ZLIB=yes

make install

cp /usr/local/sbin/haproxy /usr/sbin/
cp examples/haproxy.init /etc/init.d/haproxy
chmod 755 /etc/init.d/haproxy
mkdir -p /etc/haproxy
mkdir -p /run/haproxy

Create pem file for Haproxy

Decrypt private key
openssl rsa -in domain.com.key -out domain.com.decrypt.key

unzip nginx.zip from Starssl
cat 1_domain.com_bundle.crt domain.com.decrypt.key > domain.com.pem

Config date time

Change timezone:
dpkg-reconfigure tzdata

If you do not have root privileges or want to set for yourself a different timezone than the one the system uses, you can set the environment variable TZ. Use the command tzselect to show what value to use for TZ. 
export TZ=UTC

GIN Index on Postgres

Install postgresql-contrib package 
apt-get install postgresql-contrib-9.x
(replace x with current version in used)


Create extension pg_trgm
log in postgres with superuser role,
CREATE EXTENSION IF NOT EXISTS pg_trgm;


Create GIN index
CREATE INDEX tbdatatest_idx_date  on tbdatatest  USING GIN ( playerid gin_trgm_ops);
