Advantages of Solaris and OpenSolaris over Linux

This blog contains a summary as well as links discussing the advantages of Solaris and OpenSolaris over Linux.  This blog entry has been a good eye opener for me.  I received information that was weighted towards Solaris and decided I did not want to filter it because I thought seeing people's perspective is good.  The Linux additions have been fantastic and thanks to all the Linux feedback.  We all want truth, so hearing from both sides is excellent.  :)

Launch of Solaris Campus

I'm sitting here attending the launch of the Solaris Campus in SL.  Some hints for attending any SL meeting:

  • Make sure you have toggled your microphone off.  (bottom right hand screen)
  • Go to Edit | Preferences | General | Show Names and toggle to Never.  This can be nice if your screen gets too busy showing name tags.
  • Use camera controls to zoom in and zoom out.

Greylin has done a great job in designing and laying out the Solaris Campus. Enzo excellent job managing the launch of this campus.  Sidifen Yiyuan (Stephen Mohr)  is delivering a presentation on Solaris 10 updates.  Great presentation, the theatre is standing room only.  Presentation can be downloaded at .  There is a Solaris certification center where you can get more information on Solaris certification.

Top Things to Know if new to MySQL on Solaris

Here are ten things to know about MySQL if you are new to MySQL on Solaris:

  1. The default install is simple, easy, takes minimum resources but is not a configuration you should use for production environments.  If new to MySQL use the default install.
  2. To connect to a MySQL database server you need to know the host and the port.   The my.cnf (or my.ini) file is the startup configuration file.
  3. The mysqld background process is the database server that reads the startup configuration file.  The mysqld database server is thread based, so threads start up to manage sessions.
  4. MySQL has unique features just like other relational databases. MySQL database servers need to be configured for performance like any database server if running in a production environment.  You'd better understand these features if supporting MySQL.
  5. Before running MySQL in a production environment, you'd better understand storage engines, SQL Modes, MySQL security and the architecture of the MySQL database server.
  6. As of May 30, 2008  MySQL 5.0 is the GA release,  5.1 RC is about to go GA.  MySQL 6.0 is in alpha.  The goals of MySQL 6.x is adding a lot of online features, new important functionality with increased performance and throughout.  MySQL 6.0 will add significant scalability and functionality to the database server.
  7. Through version MySQL 5.1, there is no hot backup utility.  OS snapshots, replication, InnoDB Hot Backups are popular ways for backing up MySQL databases.  MySQL 6.x will have hot backup capability.
  8. MyISAM tables totally rock when high speed reads are very important.  Make sure you understand all characteristics or these tables before using them.
  9. InnoDB is the transactional storage engine to use through MySQL 5.1.
  10. New storage engines such as Maria, Falcon and enhancements to InnoDB are going to change the use of MySQL in the enterprise.
  11. Replication is one of the most popular features in MySQL.   It is free, relatively simple to set up and performs basic functionality of replication.  Does not contain advanced replication features but it also does not contain the complexity either.  That is what users like about MySQL replication.
  12. MySQL Cluster is a HA (high availability) environment.  MySQL Cluster works extremely well when applications leverage how MySQL Cluster works.  Make sure you understand the characteristics of MySQL Cluster before considering it for an application.
  13. Go to  http:/   and then click on Documentation.  Scroll down a little bit and find the Example Databases section.   The World, Sakila and Menagerie gzip and zip files contain SQL code for creating database schemas, building tables and storing them with data.  They provide sample data to play with.
  14. MySQL Enteprise Monitor is MySQL's management and monitoring software for managing MySQL database servers.  It contains lots of GUI interfaces and advisors.
  15. Popular software seen in MySQL environments include memcache, SQLYog, Navicat, Pentaho and Nagios.  

Why MOCA on Solaris?

Installing and configuring MySQL using the packages, RPMs and installers that can be downloaded from MySQL are easy to install. There are also numerous installers like YUM for Fedora that can install an entire LAMP or SAMP stack for you with a simple click. If all these installs are so easy why would you ever want to perform a manual install or use MOCA?

Well, database administration like life comes down to doing things easy and simple or doing things right. If you are going to perform a simple install or just want to learn MySQL, then definitely use one of the very easy install methods mentioned above. If you are concerned about any of the following perform a manual install using some set of guidelines like MOCA:
  • Installing multiple MySQL database servers on the same platform.
  • Installing multiple versions of MySQL software on the same platform.
  • Consistency of MySQL configurations across different operating systems and hardware.
  • Installations and configurations conforming to standards and guidelines.
  • Minimizing pain and anguish in your life as a DBA.
  • Avoiding evenings and weekend work.
  • Minimizing mistakes, downtime and adminstration costs.

  • If installing MySQL for development and in a small shop then simple installs are nice. That is part of the tremendous attraction of MySQL. For production DBAs installing MySQL across multiple platforms at the enterprise level, it is important to use guidelines and standards that your DBA team can control. When a lot younger I didn't mind working late hours and working on an hourly basis. Now, I prefer to minimize administration costs, late hours and minimizing pain. :)

    Installing MySQL 5.1 on Solaris 10 using MOCA


    The following instructions will lay out an installation of MySQL on Solaris using the MySQL Optimal Configuration Architecture (MOCA) for someone knowledgeable in MySQL/Solaris administration. MOCA is a set of best practices I put together to lay out a set of guidelines for installing and configuring a MySQL database server.  MOCA is designed for someone with experience with MySQL, it is not for someone brand new to MySQL.

    If you are new to MySQL or to Solaris, I recommend using the default package install for MySQL. The MySQL default install is recommended for someone new to MySQL or the operating system platform. If the default package install makes more sense for you, then you can stop reading.  This install uses MySQL 5.1.24 and it will work for any 5.1.x install (i.e. 5.1.42).

     Why Perform a Manual Install

    The default install with MySQL is great for users new to MySQL. It is simple, requires a few point and clicks and you are up and running. The problem with a default install is that it is designed to be a very simple install and take minimum resources. The default install also puts MySQL files in different locations on the filesystem dependent on the OS release and platform. The default install is not how an experienced DBA would want to set up a production database environment. It is much better to be able to control the layout and configuration of the database software for production database environments and for platforms where multiple MySQL servers may be installed in the future.

      This install assumes you have a fundamental understanding of Solaris and have an understanding of MySQL database administration fundamentals. Oracle DBAs will find this installation very similar to the concepts of the Optimal Flexible Architecture (OFA).
      For experienced MySQL DBAs a manual install is much better. For this purpose I created a best practices configuration and white paper called MOCA (MySQL Optimal Configuration Architecture). This is based on DBA best practices and should be very similar to Oracle, DB2 and SQL Server production DBAs. There are certain fundamental truths about how database servers should be installed, configured and managed. My MOCA whitepaper addresses these fundamental truths. This manual install will follow MOCA standards and conventions.

    Why MOCA? 

    Visit to get the details of the reasons behind MOCA and why it is based on best practices. There is also an example of installing MySQL on Mac OS and Linux.    In summary, MOCA focuses on:
    1. Separating database software from other software.
    2. Separating data and index files, log files for recovery, administration and backup files.
    3. Developing standard naming conventions.
    4. Defines a flexible configuration that can support multiple database servers on same platform.
    5. A consistent configuration for multiple servers and versions of MySQL database software.

    Installation Summary

    This installation looks more complex than it is.  I use this configuration for all  MySQL DBA classes.

    1. Remove old versions of MySQL if they exist.  Setup up operating system user called "mysql" and the environment for this user.
    2. Set up directories and directory permissions for all MySQL data files.
    3. Setup MySQL software and install MySQL software as mysql operating system user (not as root).  Configure the my.cnf configuration file.
    4. Create the mysql database (mysql_install_db) and setup the security environment (mysql_secure_installation). Start the mysql database server.
    5. Test the shutdown and startup of the database server. 

    Installation Environment

    The environment for this installation is Solaris 10 - Downloaded DVD iso image from website. I installed the Solaris 10 05/08 x86/x64 image for this demo (sol-10-u5-ga-x86-dvd.iso). MySQL 5.1 I downloaded from

      Before installing MySQL on my platform, make sure there are no previous versions of MySQL preinstalled. Unless you want the older version of MySQL, your life will be much easier if you remove any previous releases that are not being used.
      Read through this installation a few times before starting.

    Look for existing MySQL software

    This install uses 5.1.24, these installation procedures can be used for any 5.1.x installation. Dependent on the version of Solaris, different packages may need to be installed or removed (old MySQL installations).  

    Check to see if MySQL is installed on your current system.
    # grep mysql /etc/passwd
    # find /usr/local -name '\*mysql\*' - print # look here for MacOS, Unix/Linux
    # find /var -name '\*mysql\*' - print # good place to start with Solaris
    # find / -name "\*mysql\*' - print # look everywhere for MySQL installations

     VM Fusion Choices for Installing Solaris 10

    My choices for installing Solaris 10 in a VM Fusion environment. During the installation you will be asked to hit F2 to continue. On a MAC that will be EscapeKey-2 or FN-F2. Solaris Interactive US-English Networked - DHCP IPv6 - No You may need to specify the amount of disk space to use. I allocated 10228 MB.

      You should now be able to log in as root. With Solaris choose the Java Desktop Environment or the Common Desktop Environment (CDE), this is a personal preference.

     Removing older versions of MySQL on Solaris

    Check for MySQL packages installed and remove them.
    # pkginfo | grep mysql

    The following packages SUNWmysqlr, SUNWmysqlt, SUNWmysqlu were found and removed.
    # pkgrm SUNWmysqlr
    # pkgrm SUNWmysqlt
    # pkgrm SUNWmysqlu

    Remove old MySQL files from common directories.
    # sudo rm /usr/local/mysql
    # sudo rm -rf /Library/StartupItems/MySQLCOM/

    Setup new mysql user if one does not exist.  If a mysql user does exist, set up a password, default shell, default directory, etc.
    No mysql user was found so I added one. Add the mysql group, mysql user, password and home directory.
    # groupadd -g 300 mysql
    # useradd -u 300 -g 300 -d /export/home/mysql -s /usr/bin/bash -c "MySQL DBA" mysql
    # passwd mysql

    Login and verify the mysql user setup

    # su - mysql (or exec login mysql)

    Then define a default profile file using your favorite text editor.

    --- .bash_profile file ------
    PS1='$PWD: '
    --- end of .bash_profile file -------

    Set your environment by sourcing your profile file.

    $ cd $MYSQL_HOME
    $ .   ./.bash_profile

    Downloading MySQL 

    Go to and go to downloads. Find the distributions and choose the install release you want. I chose 5.1.24. I prefer a manual install so I choose the Solaris Tar Packages the Solaris 10 64-bit install. Select a mirror. On the Select a Mirror page, I choose No thanks, just take me to the downloads!

    MySQL Directory Organization 

    A good way to separate MySQL files and software:
    /opt/mysql/5.1.24 - Symbolic link to software directory location
    /db01/mysql/mysql01/data          - data directory
    /db02/mysql/mysql01/binlogs     - location of binary log files
    /db03/mysql/mysql01/admin       - main administration directory
    /db04/mysql/mysql01/backups    - location of backup files

    Create the following base (parent) directory to download the MySQL software into.
    # mkdir -p /opt/mysql
    # export MYSQL_NAME=mysql01

    The directory pattern of "mysql01" will be used to uniquely identify all physical files associated with this specific MySQL database server.
    Setup data directory structure
    # mkdir -p /db01/mysql/$MYSQL_NAME/data

    Setup mysql administration directory structure
    # mkdir -p /db03/mysql/$MYSQL_NAME
    # cd  /db03/mysql/$MYSQL_NAME/
    # mkdir logs errors sql startup run

    Setup binary log structure
    # mkdir -p /db02/mysql/$MYSQL_NAME/binlogs

    Setup backup directory structure for backups and exports.
    # mkdir -p /db04/mysql/$MYSQL_NAME
    # mkdir /db04/mysql/$MYSQL_NAME/backups
    # mkdir /db04/mysql/$MYSQL_NAME/exports

    Set permissions and ownership for MySQL file directories.
    # chmod -R 750                   /db\*/mysql/\*    /opt/mysql/\*
    # chown -R mysql:mysql    /db\*/mysql/\*    /opt/mysql/\*

    Before going further

    Double (triple) check all directory paths and permissions.   99.99% of issues with manual installs  are typos in the directory paths, typos in the file names or permission issues with directories.

    Double check all paths.   When you try to bring up database server, if it defaults to the default areas its because it can;t find a directory or doesn't have permission for directories specified so it will then try the default locations.

    Setup the MySQL software (as the MySQL OS user, not the root OS user)

    All following commands are run as the mysql OS user. In the /opt/mysql directory unzip and untar the MySQL software as the mysql OS user.
    $ cd /opt/mysql
    $ gunzip mysql-5.1.24-rc-solaris10-x86_64.tar.gz
    $ tar xvf mysql-5.1.24-rc-solaris10-x86_64.tar
    $ ln -s mysql-5.1.24-rc-solaris10-x86_64 5.1.24
    $ cp $MYSQL_HOME/support-files/my-small-cnf   $MYSQL_HOME/my.cnf

    Add the following entries to the my.cnf file to the [mysqld] group. This separates all your dynamic administration files, data files, and binary log files to different locations. A separate port is defined away from the default.


    Create the mysql database files for the MySQL instance. This will create the default database schemas and database files.

    $ cd $MYSQL_HOME 
    $ scripts/mysql_install_db --datadir=/db01/mysql/mysql01/data  --basedir=$MYSQL_HOME

    Verify data files and directories have been created in the datadir directory. 

    $ cd /db01/mysql/mysql01/data
    $ ls

    ib_logfile0  ib_logfile1  ibdata1      mysql        test 

    Start the MySQL database server pointing to the defined locations.
    $ cd /opt/mysql/5.1.24
    $ bin/mysqld_safe --defaults-file=$MYSQL_HOME/my.cnf &

    If there are socket errors:

    i.e.  MySQL client cannot start with the error "cannot connect to the MySQL server through socket <filename>


    Each MySQL needs to write to a unique socket file.  If you don't specify one, a default one is chosen which may not have the appropriate permissions.   Make sure the permissions are set properly (owned by mysql).  The socket needs to match for the mysqld and the client side.  Make sure the socket definitions match in the my.cnf file in the [mysqld] and [client] groups.

    Verify the mysqld background process is running as well as the mysqld_safe monitoring process. The mysqld background process should be up and running.

    $ ps -ef |grep mysql

    Clean up the database server by adding passwords and getting rid of anonymous users.  If there are problems with the mysql_secure_installation script, then set the password manually and get rid of the anonymous accounts and any accounts with no passwords.

    $ cd $MYSQL_HOME 
    $ bin/mysql_secure_installation 

    Shutdown the MySQL server to verify you can shutdown and startup the MySQL instance.

    $ mysqladmin --defaults-file= $MYSQL_HOME/my.cnf   shutdown -uroot -p
    $ cd $MYSQL_HOME

    $ bin/mysqld_safe --defaults-file= $MYSQL_HOME/my.cnf

    You're up and running have fun. Once you are confortable with this configuration layout, you can create a Unix shell script that will automate almost the entire process. With a shell script automation the install takes about ten minutes.
