title: Odoo11 install on CentoOS7
body: <p>I just bought new VPS server installed CentOS7 and tried to install <a href="https://www.odoo.com/" rel="nofollow noreferrer">Odoo11</a> on my server.</p>
  
  <p>So I researched some articles and tried following.</p>
  
  <pre><code>// Install requirement packages
  [root@odoo ~]# yum update -y 
  [root@odoo ~]# yum install epel-release -y 
  [root@odoo ~]# yum install fontconfig libpng libX11 libXext libXrender xorg-x11-fonts-Type1 xorg-x11-fonts-75dpi wkhtmltopdf yum-utils -y 
  
  // Install PostgreSQL
  [root@odoo ~]# yum install postgresql-server -y 
  [root@odoo ~]# postgresql-setup initdb
  [root@odoo ~]# systemctl enable postgresql
  [root@odoo ~]# systemctl start postgresql
  
  // Install Odoo
  [root@odoo ~]# yum-config-manager --add-repo=https://nightly.odoo.com/11.0/nightly/rpm/odoo.repo 
  [root@odoo ~]# yum install odoo -y 
  </code></pre>
  
  <p>After run last command, I get error.</p>
  
  <blockquote>
    <p>...</p>
