I am trying to install the WildFly 8.0.0.Final application server on a Virtual Machine running Ubuntu 12.04 LTS. I've done some searches on Google, but I found only third-party scripts and, I think, non standard ways to do this.

Currently, to start the server, I open an SSH connection to the virtual machine and run the following commands:

cd <WILDFLY_HOME>/bin
nohup standalone.sh -b=0.0.0.0 -bmanagement=0.0.0.0 > /dev/null &

And to stop:

kill <pid of java process running wildfly>

But, what is the best way to install the server as a service on Ubuntu? If I restart the machine, the server will start automatically?

My environment:

• Ubuntu 12.04 LTS;
• Java 7;
• WildFly 8.0.0 Final;

I think this is a simple question, but let me explain better. I have the following development environment:

• Ubuntu Server 12.04 LTS;
• Apache 2.4;
• PHP 5.5;

Everything is working fine, except the VirtualHost configuration. I want to deploy two applications: Drupal and Wordpress. Each application has your own directory, for example:

• Drupal: /l/disk0/drupal/public_html;
• Wordpress: /l/disk0/wordpress/public_html;

In default site, VirtualHost configuration points to /var/www as document root. I want to disable this default-site configuration and I want to create two VirtualHosts, one for Drupal and another one for Wordpress.

However, this is a development environment and there is no domain here. I've searched many sites and I found a lot of tutorials, all of them explains how to do this with domains, but not with subdirectories.

After doing the configuration, the URL to access my applications will be:

 - http://example.com/wordpress;
 - http://example.com/drupal;

I already try with this VirtualHost:

<VirtualHost *:80>
        ServerName example.com
        ServerAdmin [email protected]
        DocumentRoot /l/disk0/site/public_html

        <Directory />
                AllowOverride None
        </Directory>

        Alias /site /l/disk0/site/public_html
        <Directory /l/disk0/site/public_html>
                Options MultiViews Indexes Includes FollowSymLinks ExecCGI
                AllowOverride All
                Require all granted
                allow from all
        </Directory>

        RewriteEngine On
        LogLevel warn
        ErrorLog "/l/disk0/site/logs/apache/site/error.log"
        CustomLog "/l/disk0/site/logs/apache/site/access.log" combined
        SSLProxyEngine on
</VirtualHost>

Didn't work.

I'm having some troubles with CPU and memory usage with an Apache Web Server.

We're running an Ubuntu Server 12.04 LTS on a Virtual Machine. Our server has following specs:

• 8GB RAM;
• 4 vCPUs (12ghz);

We configured the server to run a Drupal (7.23) based website. So we installed Apache, PHP, MySQL... The versions are below:

• Apache 2.2.22;
• PHP 5.3.10 (The PHP are running as Apache Module.);
• APC 3.1.7;
• MySQL 5.5.31 (all innodb tables);

I am running some apache modules too. Take a look (apachectl -M):

• core_module (static)
• log_config_module (static)
• logio_module (static)
• mpm_prefork_module (static)
• http_module (static)
• so_module (static)
• actions_module (shared)
• alias_module (shared)
• authz_host_module (shared)
• deflate_module (shared)
• dir_module (shared)
• env_module (shared)
• include_module (shared)
• mime_module (shared)
• php5_module (shared)
• proxy_module (shared)
• proxy_http_module (shared)
• reqtimeout_module (shared)
• rewrite_module (shared)
• setenvif_module (shared)
• ssl_module (shared)
• status_module (shared)

On apache2.conf, we have this config:

    Timeout 90
    KeepAlive On
    MaxKeepAliveRequests 80
    KeepAliveTimeout 5
    HostnameLookups Off
    LogLevel warn

    <IfModule mpm_prefork_module>
        StartServers          10
        MinSpareServers       10
        MaxSpareServers       30
        MaxClients           120
        MaxRequestsPerChild 1000
    </IfModule>

The Virtual Host of my site:

    <VirtualHost *:80>
        ServerName blabla.bla.bla
        ServerAdmin [email protected]
        DocumentRoot /l/disk0/site/public_html

        <Directory />
            AllowOverride None
        </Directory>

        <Directory /l/disk0/site/public_html>
            Options MultiViews Indexes Includes FollowSymLinks ExecCGI
            AllowOverride All
            Order allow,deny
            allow from all
        </Directory>

        LogLevel warn
        ErrorLog "/l/disk0/site/logs/apache/site/error.log"
        CustomLog "/l/disk0/site/logs/apache/sit/access.log" combined
        SSLProxyEngine on
        RewriteEngine   on
        RewriteLog     logs/rewrite_www_log
        RewriteLogLevel        0

        Include rewrites-www.conf
</VirtualHost>

My site is simple and don't have many visitors. I am talking about 500 visitors a day maybe. Can Drupal use so much CPU? Or is it a module?

Other problem is memory usage. When a process is created, 80M is allocated for apache2. I think is too much.

My problem is that CPU (all cores) have a high utilisation. Most of time, it's hitting between 90% and 100% usage! The offending process is the apache2. Memory is also consumed without pity. Of a 8GB total, the consumed memory is about 6.5GB to 7.5GB. I don't know if my apache configuration is wrong or if I'm really need more hardware (I guess not). Drupal can cause high CPU load?

When the CPU usage hits 100%, the site goes down and we have to restart apache. I did a workaround solution with Drupal using APC and installing Boost. had some effectiveness, but CPU utilisation still high. Very high.

If you need more information, like Drupal modules and PHP extensions. Please let me know.
