We’re going to use Puppet to install Apache and WordPress.

This article is part of the Homelab Project with KVM, Katello and Puppet series.

Homelab

We have two CentOS 7 servers installed which we want to configure as follows:

web1.hl.local (10.11.1.21) – Apache server with WordPress and NFS mount
web2.hl.local (10.11.1.22) – Apache server with WordPress and NFS mount

SELinux set to enforcing mode.

See the image below to identify the homelab part this article applies to.

WordPress from a Custom Tarball

We won’t be downloading WordPress from the Internet, but will be using our own custom build (tarball) instead. Each build is source controlled and tested locally prior releasing to the environment.

The name of the tarball is wordpress-latest.tar.gz, and it’s currently stored on the Katello server under /var/www/html/pub/. This allows us to pull the archive from https://katello.hl.local/pub/wordpress-latest.tar.gz.

Note that the file wp-config.php is never stored inside the tarball, but gets generated by Puppet.

Redundand Apache/MySQL Architecture

To increase redundancy, each Apache server will be configured to use a different MySQL database server.

Since our MySQL nodes are configured to use a Master/Master replication, there should, in theory, be no difference in terms of data that’s stored on each VM.

We’ll plug web1.hl.local in to db1.hl.local, and web2.hl.local in to db2.hl.local.

NFS Mount for Uploads

Both Apache servers will need an NFS client configured to mount shared storage.

While users can use either of the Apache servers to upload files, we need to ensure that regardless of the VM they end up on, files across WordPress instances are the same. We could use rsync to solve the problem, but I’m not sure on how well that would scale. Perhaps something to look at in the future.

Configuration with Puppet

Puppet master runs on the Katello server.

Puppet Modules

We use the following Puppet modules:

1. derdanne-nfs – to mount an NFS share for WordPress /uploads folder
2. puppetlabs-apache – to install and configure Apache
3. puppet-selinux – to configure SELinux booleans (e.g. httpd_use_nfs)
4. hunner-wordpress – to install WordPress

Please see each module’s documentation for features supported and configuration options available.

Firewall Configuration

Configure both Apache servers to allow HTTPS traffic:

firewall { ‘007 allow HTTPS’:
dport => ‘443’,
source => ‘10.11.1.0/24’,
proto => tcp,
action => accept,
}

There may be an insignificant performance penalty incurred while using encryption between HAProxy and Apache compared to plaintext HTTP, but we want to ensure that traffic is secured. HAProxy can be re-configured to offload TLS if this becomes a problem.

SELinux Booleans

Configure SELinux on both Apache servers. These are required in order to allow Apache to use NFS and connect to a remote MySQL instance. We also want to allow Apache (WordPress) to send email notifications.

selinux::boolean { ‘httpd_use_nfs’:
persistent => true, ensure => ‘on’
}->
selinux::boolean { ‘httpd_can_network_connect_db’:
persistent => true, ensure => ‘on’
}->
selinux::boolean { ‘httpd_can_sendmail’:
persistent => true, ensure => ‘on’
}

Configure NFS Client

This needs to be applied for both Apache servers.

class { ‘::nfs’:
server_enabled => false,
client_enabled => true,
}->
nfs::client::mount { ‘/var/www/html/wp-content/uploads’:
server => ‘nfsvip.hl.local’,
share => ‘/nfsshare/uploads’,
}

The virtual IP (which NFS cluster runs on) is 10.11.1.31, and the DNS name is nfsvip.hl.local. The cluster is configured to export /nfsshare. See here for more info.

Install Apache

This needs to be applied for both Apache servers.

We deploy one Apache virtualhost, and configure log forwarding to Graylog (see the custom_fragment section). I wrote a separate post for how to send Apache logs to Graylog, take a look here if you need more info.

TLS certificates are taken care of by the main Puppet manifest for the environment. See here for more info.

package { ‘php-mysql’:
ensure => ‘installed’
}->
class { ‘apache’:
default_vhost => false,
default_ssl_vhost => false,
default_mods => false,
mpm_module => ‘prefork’,
server_signature => ‘Off’,
server_tokens => ‘Prod’,
trace_enable => ‘Off’,
log_formats => { graylog_access => ‘{ “version”: “1.1”, “host”: “%V”, “short_message”: “%r”, “timestamp”: %{%s}t, “level”: 6, “_user_agent”: “%i”, “_source_ip”: “%h”, “_duration_usec”: %D, “_duration_sec”: %T, “_request_size_byte”: %O, “_http_status_orig”: %s, “_http_status”: %>s, “_http_request_path”: “%U”, “_http_request”: “%U%q”, “_http_method”: “%m”, “_http_referer”: “%i”, “_from_apache”: “true” }’ },
}
include apache::mod::alias
include apache::mod::headers
include apache::mod::php
include apache::mod::rewrite
include apache::mod::ssl
::apache::mod { ‘logio’: }

## Configure VirtualHosts
apache::vhost { ‘blog_https’:
port => 443,
servername => ‘blog.hl.local’,
docroot => ‘/var/www/html’,
manage_docroot => false,
options => [‘FollowSymLinks’,’MultiViews’],
override => ‘All’,
suphp_engine => ‘off’,
ssl => true,
ssl_cert => ‘/etc/pki/tls/certs/hl.crt’,
ssl_key => ‘/etc/pki/tls/private/hl.key’,
ssl_protocol => [‘all’, ‘-SSLv2’, ‘-SSLv3’],
ssl_cipher => ‘HIGH:!aNULL!MD5:!RC4’,
ssl_honorcipherorder => ‘On’,
redirectmatch_status => [‘301’],
redirectmatch_regexp => [‘(.*).gz’],
redirectmatch_dest => [‘/’],
custom_fragment => ‘CustomLog “|/usr/bin/nc -u syslog.hl.local 12201” graylog_access’,
}

Install WordPress from Our Custom Tarball

We want to use our existing MySQL configuration, meaning that we don’t want WordPress creating any databases nor users. The details below are the ones we used when setting up MySQL servers.

The only thing that’s going to different here is the db_host parameter – one Apache server uses db1.hl.local, another one uses db2.hl.local.

class { ‘wordpress’:
db_user => ‘dbuser1’,
db_password => ‘PleaseChangeMe’,
db_name => ‘blog’,
db_host => ‘db1.hl.local’,
create_db => false,
create_db_user => false,
install_dir => ‘/var/www/html’,
install_url => ‘http://katello.hl.local/pub’,
version => ‘latest’,
wp_owner => ‘apache’,
wp_group => ‘root’,
}

Note how we set the owner to apache. This is something we may want to harden further depending on security requirements.

If all goes well, we should end up with both servers using the NFS share:

[[email protected] ~]# df -h|egrep “File|uploads”
Filesystem Size Used Avail Use% Mounted on
nfsvip.hl.local:/nfsshare/uploads 2.0G 53M 1.9G 3% /var/www/html/wp-content/uploads
[[email protected] ~]# df -h|egrep “File|uploads”
Filesystem Size Used Avail Use% Mounted on
nfsvip.hl.local:/nfsshare/uploads 2.0G 53M 1.9G 3% /var/www/html/wp-content/uploads

We should also be able to create Graylog dashboard widgets by using Apache data, e.g.:

What’s Next?

We’ll look into putting a pair of HAProxy servers in front of Apache to perform load balancing.

Example of near single-click installation of containerised apps with Portainer

I met up with the team from Portainer.io in my home town of Wellington, New Zealand when they paid a visit to a Linux user group there. Their product is an awesome graphical, browser based docker container management system. You can download containers that are pre-baked, ready to go, such a MongoDB and Apache as well as many other popular tools of the trade. Not only can you roll containers in seconds, you can also work storage volumes and networking in just a few clicks of your mouse.

Want to know more?

If you use Docker at all, or if you’ve wanted to start looking into containerisation and DevOps, Portainer really is one of the best tools to get started with; It is currently compatible with Docker engine and Docker Swarm. Portainer is completely free and open source. If you are interested in knowing more, you should check out this review over at 2daygeek.

The perl package now uses a versioned path for compiled modules. This means
that modules built for a non-matching perl version will not be loaded any more
and must be rebuilt.

A pacman hook warns about affected modules during the upgrade by showing output
like this:

WARNING: ‘/usr/lib/perl5/vendor_perl’ contains data from at least 143 packages which will NOT be used by the installed perl interpreter.
-> Run the following command to get a list of affected packages: pacman -Qqo ‘/usr/lib/perl5/vendor_perl’

You must rebuild all affected packages against the new perl package before you
can use them again. The change also affects modules installed directly via
CPAN. Rebuilding will also be necessary again with future major perl updates
like 5.28 and 5.30.

Please note that rebuilding was already required for major updates prior to
this change, however now perl will no longer try to load the modules and then fail in strange ways.

If the build system of some software does not detect the change automatically,
you can use perl -V:vendorarch in your PKGBUILD to query perl for the
correct path. There is also sitearch for software that is not packaged with
pacman.

1) Arch Anywhere 2.2.5

Arch Linux is a powerful rolling Linux distribution, that hasn’t always been particularly easy for new users to install and deploy. The goal of the Arch Anywhere system is to provide new and old users with the ability to install a fully custom Arch Linux system in minutes.

Arch Anywhere 2.2.5. This release is focused mainly on bug fixes. The label issue when using UEFI boot on USB has been resolved. I have also fixed a few minor bugs in the installer. I’ve added lxdm-gtk3 for users who select lxde-gtk3 (this resolves a conflict between lxdm & lxdm-gtk3). I’ve also made some tweaks and updates to the Arch Anywhere XFCE4 Desktop. This includes color and theme updates. Have also updated and improved the .zshrc for users who select zsh as their shell.

2) BitKey

Lots of Linux distribution are used by Bitcoin users, but BitKey takes it a step further. BitKey is a purpose-built for Bitcoin with a several bitcoin packages and security to match. The BitKey distribution is based on TurnKey Linux, which in turn is a Debian based system.

BitKey is a side project by the core developers of TurnKey GNU/Linux. We couldn’t find a solution that satisfied our paranoia so we rolled our own.* Refreshed component versions and base OS to Debian Jessie, thanks to Yannick Heneault.* Manually verified & signed integrity of upstream components* New Bitcoin apps: warpwallet, coinbin & libbitcoin-explorer (bx)* New packages: secure-delete, dosfstools (mkfs.vfat)* Added background color labels to boot modesDesktop UX: cut and paste, improved keybindings

3) Vinux 5.1

Vinux is an interesting Ubuntu-based distribution that is built to help visually impaired users. The system directly integrates the Orca screen reader to help users navigate the Linux system. The new release includes the following updates:

• Up to date accessibility infrastructure.
• Gnome-ORca 3.20 with updates available for 3.22
• AT-SPI 2.20 with updates available for 2.22
• Brltty 5.4
• Speech-dispatcher 0.8.5
• Liblouis 2.6.2

On this optimization process, we will go over the Apache core configuration and modules that are part of Apache core. We think that with the correct settings of Apache and MySQL you can get excellent results and the correct level of resource use without installing third-party proxy and cache modules. So let’s start,

Apache & PHP

In the first stage we run the Easy Apache and selected the following:

• Apache Version 2.4+

• PHP Version 5.6+

• In step 5 “Exhaustive Options List” select

– Deflate

– Expires

– MPM Worker

After Easy Apache finished go to your WHM » Service Configuration » Apache Configuration » “Global Configuration” and set the values by the level of resources available on your server.

Apache Directive (From 2GB memory or less and to 12GB+ memory)

StartServers 4 8 16
MinSpareServers 4 8 16
MaxSpareServers 8 16 32
ServerLimit 128 256 512
MaxRequestWorkers 150 250 500
MaxConnectionsPerChild 1000 2500 5000
Keep-Alive On On On
Keep-Alive Timeout 1 1 1
Max Keep-Alive Requests 30 30 30
Timeout 60 60 60

Now go to WHM » Service Configuration » Apache Configuration » Include Editor » “Pre VirtualHost Include” and allow users minimal cache and data compression to allow the server to work less for the same things by pasting the code below into the text field.

# Cache Control Settings for one hour cache
<FilesMatch “.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$”>
Header set Cache-Control “max-age=3600, public”
</FilesMatch>

<FilesMatch “.(xml|txt)$”>
Header set Cache-Control “max-age=3600, public, must-revalidate”
</FilesMatch>

<FilesMatch “.(html|htm)$”>
Header set Cache-Control “max-age=3600, must-revalidate”
</FilesMatch>

# Mod Deflate performs data compression
<IfModule mod_deflate.c>
<FilesMatch “.(js|css|html|php|xml|jpg|png|gif)$”>
SetOutputFilter DEFLATE
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4.0[678] no-gzip
BrowserMatch bMSIE no-gzip
</FilesMatch>
</IfModule>

Go to WHM » Service Configuration » “PHP Configuration Editor” and set the parameters according to your needs:

– memory_limit

– max_execution_time

– max_input_time

Many thanks to all of you, for your donations and for your support.

I hope you had a great summer (or winter if you live in the South hemisphere). Here we’re eager to get into September, with LMDE 3 and Mint 19 behind us, we’re ready to get started on some of the big projects.

LMDE

LMDE 3 was released today. I’d like to thank all the people involved in the project and also all the people who reported issues to us and who helped us fix bugs during the BETA.

The upgrade path for the Cinnamon edition was also opened. Timeshift, Slick Greeter and mintupgrade were backported towards LMDE 2 to facilitate the upgrade and the switch from MDM with sysvinit to LightDM with Systemd.

If you are running LMDE 2 Cinnamon, please upgrade before the end of the year. We’ll continue to support LMDE 2 until the 1st of January 2019.

The LMDE 2 MATE edition cannot be upgraded (Debian’s version of MATE is only 1.16 and this edition is no longer present in LMDE 3), we recommend users perform data and software backups and upgrade their OS via fresh installations. MATE packages in LMDE 2 will also be supported until the 1st of the January 2019.

Software Sources

The Software Sources tool was given a new look. Similar to the welcome screen, it’s now using an Xapp sidebar and a headerbar.

The optional sources section was also simplified and we’re planning to add a new option to make it easy to add debug repositories (to adapt to Debian’s decision to move debug symbols to dbgsym packages/repositories).

Mint-Y theme contrast

Within the feedback we received during the release of Linux Mint 19 it was highlighted that the Mint-Y theme didn’t have enough contrast and that some labels were hard to read.

Work started on improving the theme’s contrast.

Here’s a picture of Timeshift as it appears in Mint 19:

And here’s a picture of it with the contrast improvements:

The foreground colors were darkened (this is particularly visible here in the symbolic toolbar icons). The titlebar label is more pronounced as well, and the frame and contour of some of the widgets appear more clearly within the user interface.

SIGKILL (9) – Kill signal. Use SIGKILL as a last resort to kill process. This will not save data or cleaning kill the process.

SIGTERM (15) – Termination signal. This is the default and safest way to kill process.

The difference between 9 and 15 is, the default action for both of them is to terminate

the process, but 9 can’t be caught or ignored. So if signal 9 gets sent, the process is

guaranteed to die, immediately. If a sig 15 is sent, the process can catch it and perform cleanups.

Signal name	Signal value	Effect
SIGHUP	1	Hangup
SIGINT	2	Interrupt from keyboard
SIGKILL	9	Kill signal
SIGTERM	15	Termination signal
SIGSTOP	17,19,23	Stop the process

Darksiders II runs much better with DXVK implemented. There are still some graphical flickering in the sky, but its not a “game breaker”. I was able to play on my GeForce GTX 1060 with great frame rates and no other noticable issues. Previously when I played Darksiders a few years ago, I played through the entire game with a few annoying graphical bugs. But those are now gone and it runs beautifully.
