Basically follow this link will work.
To give access of remote users using postgresql-client
, one need to add the following line in /etc/postgresql/9.3/main/pg_hba.conf
.
host all all 0.0.0.0/0 md5

My original plan is to setup a good viewing environment for markdown
files (analyzing results produced by some template engine). No blog functions are needed. However, it turns out to be tedious and not as useful as expected.
To setup Ruby, basically following this link is fine. Note that rails (or at least node.js) is needed. Pure ruby is not enough.
To setup Jekyll, following this link. After installation, running
$ bundle exec jekyll serve
I face this problem because I accidentally try to install MongoDB 3.0.x (from http://repo.mongodb.org/apt/ubuntu) while actually a MongoDB 2.6.8 (provided by ubuntu) is already installed in the same computer. Therefore, both mongod
and mongo
commands are still point to the old version (which doesn't work actually). Since the official installation document said that "You cannot install this package concurrently with the mongodb, mongodb-server, or mongodb-clients packages provided by Ubuntu", this just cannot work.
A better way is to first completely uninstalled the older version before install the new one, but I already missed that time. So
sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev
sudo apt-get purge mongodb-10gen
cannot remove it completely (not sure whether that's the exact case), and \usr\bin\mongo
and ``\usr\bin\mongo
