Installing Neo4j on CENTOS 6.7?
<p>I have installed Neo4j by the following steps:</p>

<pre><code>cd /tmp
wget http://debian.neo4j.org/neotechnology.gpg.key
sudo rpm --import neotechnology.gpg.key
</code></pre>

<p>then create neo4j.repo file :</p>

<pre><code>[neo4j] 
name=Neo4j Yum Repo 
baseurl=http://yum.neo4j.org 
enabled=1 
gpgcheck=1
</code></pre>

<p>move it into:</p>

<pre><code>sudo cp neo4j.repo /etc/yum.repos.d/
</code></pre>

<p>Finally running the command to install neo4j</p>

<pre><code>sudo yum install neo4j
</code></pre>

<p>But, it failed to start! and gave this Exception:</p>

<pre><code>Caused by: org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.server.database.LifecycleManagingDatabase@621a8172' was successfully initialized, but failed to start. Please see attached cause exception.
