1. Install Emacs

tar Jxf emacs-24.3.tar.xz
./configure --with-x-toolkit=no --with-xpm=no --with-jpeg=no --with-png=no --with-gif=no --with-tiff=no
make && make install

2. Get configuration

git clone git@github.com:TheWaWaR/.emacs.d.git

# In emacs, compile all files in .emacs.d directory
C-u 0 M-x byte-recompile-directory

Installation

Install Postgresql 9.1 server on CentOS 6

rpm -Uvh http://yum.pgrpms.org/9.1/redhat/rhel-6-x86_64/pgdg-centos91-9.1-4.noarch.rpm
yum install postgresql91-server.x86_64 postgresql91-devel.x86_64

Authentication issue

By default, the authentication method is (peer for Unix domain socket connections AND ident for IPV4 local connections), if you login postgresql server by:

psql -d myDB -U kafka -h 127.0.0.1

It will report an error like this:

psql: FATAL:  Ident authentication failed for user "kafka"

In pg_hba.conf, Change all authentication type to md5 (means by password that after md5 processed).

Authentication Methods

[Option] :: In postgresql.conf , Change listen_addresses from localhost to * so you can connect postgresql from remote host.

If you get message like:

psql: FATAL:  no pg_hba.conf entry for host "115.192.190.55", user "postgres", database "postgres", SSL off

You should change something in file pg_hba.conf, add a line like this:

host    all             all             0.0.0.0/0            md5

FAQ

1. How to import(or export) data or scheme from .sql file?

psql -U userName dbName < DATA_OR_SCHEME.sql

pg_dump -U userName dbname > output.sql
