Hey you!

As said in the part 1 of this article, I will be covering here:

• How to create a openconnect init script

So, concerning the init script I will be posting parts of the script first, and then will put a link for download at the end.

First of all, we need the shebang (#!/bin/bash) and then global variables that will be used along the script:

# Path variables
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# VPN Variables
IFACE="sslvpn"
VPN_USER="vpn_user"
VPN_HOST="sslvpn.yourdomain.com"
VPN_PASS="vpn_password"
PID="/var/run/openconnect.pid"
TEMP_LOG="/tmp/status.txt"
INFO="Usage: $(basename "$0") (start|stop|status|restart)"

You can also define most of these options in a …

If you are importing large CSV or SQL dumps to MySQL, chances are you were looking for ways to see how far the import has gone. If you know how many rows there are from the file being imported, you can do a SELECT COUNT(*) but that would take sometime for the query to finish especially on really big imports.

Using lsof, you can monitor the current file offset to which a process is reading from using the -o option. Knowing the size of the file and some snapshots of the offset, you can get a somewhat rough idea of how fast the import goes. Note though that this is only file-read-pace not actual import speed as MySQL import can vary depending on a number of conditions i.e. table growth, secondary indexes, etc.

Let’s say I am importing a 1.1G CSV file into a table.

Here’s a solution to the not-so-long-standing issue of the Percona yum repo being broken for the CentOS 6 x86_64 version of the Percona-toolkit package. The repo listing is reporting an older version of the RPM which is not available on the site, so to fix this you just have to download the newer file and tell yum to add it locally. The side benefit is that you can use Yum to manage the RPM without adding the Percona repo, since the default settings for their repo could/have/had caused conflicts with Base Repo versions of MySQL packages; the Percona repo instructions set ‘enabled=1′ — not a great idea if you’re not setup to use the Yum priorities method of repo weighting.

So, if you see this after installing the repo via the instructions on their site:
Downloading Packages:

There have been many articles about the downtime issue with Cloudflare last week, so I won’t get into the technical details of that. However, there’s the fine print to remember. Consider this a subtle reminder that core Internet infrastructure services like Cloudflare’s DNS-based “Always Online” caching and packet inspection security services do not come with Service Level Agreements even at the “Pro” account level. Even with a Pro account you are paying for a service with no uptime guarantee and you must only hope that it resolves your sites the majority of the time. This is fine, this is what the contract says: no SLA unless you pay for the Business account. An odd naming convention given that most Professionals are using their websites for business and would want the SLA, but I digress.

So, the SLA is not really the issue if you look at the architectural alternatives to building an architecture that desires availability when …

Congratulations to the openSUSE community on a successful release of openSUSE 12.3. A highlight worth mentioning is that MariaDB is now the default as opposed to MySQL. What are you waiting for, download it!

From the features list, here’s an excerpt focusing on MariaDB & MySQL:

openSUSE has moved from MySQL to MariaDB as default. MariaDB was first shipped with openSUSE 11.3 back in 2010. Over the years it proved itself and starting with 12.3 openSUSE is replacing default MySQL implementation with MariaDB. This means that whole distribution is compiled against MariaDB and in ‘M’ in LAMP means MariaDB from now. As MariaDB is a drop-in …

This is just for testing purposes, but you might want to play around with MariaDB 5.5.29 coming via the CentOS 6 repositories as mentioned in this post. Please test it out and report bugs if required. The process was simple on a fresh install:

yum update
cd /etc/yum.repos.d/
wget http://dev.centos.org/centos/6/mariadb/mariadb.repo
yum list mariadb\*
yum install mariadb-server mariadb
/etc/init.d/mysqld start

That’s it, it just works. It comes with MEMORY, CSV, MRG_MYISAM, BLACKHOLE, MyISAM, PERFORMANCE_SCHEMA, ARCHIVE, FEDERATED, InnoDB (XtraDB) and Aria.

Remember this replaces mysql-libs, and is set to replace MySQL in your install. Here’s hoping it hits mainline CentOS soon.

I’m going to take the numbers from my previous post, MySQL Modularity, Are We There Yet? for the “kernel” size of MySQL – that is, everything that isn’t a plugin or storage engine.

For Linux kernel, I’m just going to use the a-bit-old git tree I have on my laptop. I’ve decided that the following directories are for “plugins” drivers/ arch/ sound/ firmware/ crypto/ usr/ virt/ tools/ scripts/ fs/*/* and everything else is core kernel code.
