After successfully installing MySQL on Oracle Enterprise Linux installing a LAMP (Linux/Apache/MySQL/PHP) stack can also be performed with a single command:

$ yum install -y httpd php php-mysql
# Start the Apache Httpd Process
$ /etc/init.d/httpd start

To test and confirm Apache Httpd and PHP, we can use the CLI browser lynx:

$ yum install -y lynx
$ echo "<? phpinfo() ?>" > /var/www/html/phpinfo.php
$ lynx http://localhost/phpinfo.php

If successful, you will find a web page that contains the following.

We’re well into summer and almost at our 200th edition of Log Buffer, a blog of blogs about the database world.

Remember if you find a link or interesting blog post that you think Log Buffer should mention, send a note to the editor at Log Buffer and be sure to include the link, and a short note outlining why you think that particular post would be of value to other DBAs, or what you learned from reading it.

Now on to our weekly reading in Log Buffer #194:

Oracle Exadata is a topic that is getting hotter and hotter. Following Pythian’s announcement of Exadata services Oracle’s Greg Rahn …

One of the significant benefits of MySQL is it’s ease of use. Generally already installed on most Linux systems, MySQL can be installed by a single command if not yet present. On Oracle Enterprise Linux 5.4 you can use the following commands to check for MySQL, configure your yum repository and install MySQL.

# Check if already installed
$ rpm -qa | grep -i mysql

# Configure yum repository on new server
$ su -
$ cd /tmp
$ wget http://public-yum.oracle.com/public-yum-el5.repo
$ sed -e "s/enabled=0/enabled=1/" public-yum-el5.repo > /etc/yum.repos.d/public-yum-el5.repo

# Install MySQL
$ yum install -y mysql-server mysql

# Start and test MySQL Instance
$ /etc/init.d/mysqld start
$ mysql -uroot -e "SELECT VERSION"

I will be one of 18 MySQL speakers at Oracle Open World 2010 at the first ever MySQL Sunday. With a great diversity of technical, community and product talks this will be a great opportunity to get a cross section of MySQL content. Combined with Java One, this year’s Oracle Open World will include a lot more opportunity of technical and developer content then the more regular marketing material.

As the program chair for the first dedicated MySQL track at last month’s ODTUG Kaleidoscope 2010 our MySQL community now includes a larger number of target people. From the Oracle community come many highly technical and skilled resources, some with an understanding or appreciation of MySQL and many that are new to MySQL.

This is a great opportunity to share our knowledge and experience with MySQL.

Ronald saved me a post by giving his feedback on a few Oracle conferences that now have MySQL content.

My opinion is pretty much a summary of Ronald’s post, so I won’t repeat it here. Instead, I’ll post about a conference he did not, the 4th Extremely Large Databases Conference. I am particularly interested in any MySQL folks planning to attend (I would expect Tokutek to be represented, and maybe even the Calpont folks).

Most of this is directly from an e-mail I received from Jacek Becla, who had a keynote at the 2008 MySQL User Conference and Expo. If you also received this e-mail, please feel free to skip …

We recently held a dedicated MySQL Track at ODTUG Kaleidoscope 2010 conference for 4 days. This is the first of many Oracle events that will begin to include dedicated MySQL content.

If your attending OSCON 2010 in the next few weeks you will see a number of MySQL presentations.

MySQL will be represented at Open World 2010 in September with MySQL Sunday. Giuseppe has created a great one page summary of speakers. This event is described as technical sessions, an un-conference and an fireside chat with Edward Screven. I’ve seen tickets listed at $50 or $75 for the day.

Open SQL Camp will be held in …

A couple of new webinar recordings are available from our web site:

• Upgrading to Pacemaker on Debian squeeze tells you all there is to know about upgrading to the Pacemaker cluster manager on the upcoming Debian release, “squeeze”.
• High Availability for Oracle databases shows you how to leverage the Linux cluster stack to deploy highly available Oracle databases.

Like our live webinars, the recordings are of course free of charge. Enjoy!

A long time ago, in the early 1980's, I decided to change jobs. I was a young guy, with no real experience of commercial software or anything like that, rather I was a self-taught sysadmin for an ancient UNix system. The company I worked for was in the Telco business, so I looked for another job where I could develop myself and at the same to use my telco knowledge.

I found a Telco startup, privately held. I must say that the fact that it was privately held meant nothing to me at the time. Nothing. They were building a system, the servers were VAXes running VMS, and again a became a sysadmin.

Having been sysadmin at this company for a while, building up the central datacenter (to be honest, in todays words, that was what I was doing, but at the time, I had no real clue. I was mosr enthusiastic and ready to take on any task than I was smart or intelligent or knew what I was doing, really). But I wanted to develop myself, …
