Lasso 9 On Ubuntu 9.10 (Karmic Koala) Guide

Direction to get Lasso 9 up and running on Ubuntu Server Edition 9.10

Below is a setup guide to get Lasso 9 running on the latest version of Ubuntu Server (9.10 - Karmic Koala) It assumes you are starting from scratch with just a default installation of the Server OS.

Two things to note

• To get it to work, I had to symbolically link 3 shared libraries that Lasso 9 was expecting to have a different name (Based on how CentOS names the libraries or on Ubuntu having a more up-to-date version.) Because of this and because I haven't thoroughly tested it, there might be bugs.
• This setup does not have lassoserver start when Apache starts - you must start it manually. I ran into some problems getting the automatic startup with apache working. I thought I had it figured out, and then ran into more bugs. Hopefully I, or someone else, will figure this out and update the article appropriately.

Install Packages

1. Login as root

$> sudo su -

2. Update all existing packages

#> apt-get upgrade

3. Install Java

#> apt-get install openjdk-6-jre-headless

4. Install Mysql

#> apt-get install mysql-server mysql-client

5. Install Apache and mod_fastcgi

#> apt-get install apache2 libapache2-mod-fastcgi

6. Install Subversion to get Lasso

#> apt-get install subversion

7. Additional required libraries

#> apt-get install libcurl3 libxslt1.1

Create Symbolic Links

This is controversial - it got lasso to work for me, but i'm not sure it didn't introduce bugs to point to newer / possibly different libraries

$> sudo su -
     #> ln -s /lib/libcrypto.so.0.9.8 /lib/libcrypto.so.6
     #> ln -s /lib/libssl.so.0.9.8 /lib/libssl.so.6
     #> ln -s /usr/lib/libldap-2.4.so.2 /usr/lib/libldap-2.3.so.0

Install Lasso

1. If you are currently root, exit to your normal admin shell.

#> exit

2. Download Lasso 9 via SVN

$> sudo svn co http://download.lassosoft.com/svn/lasso/lasso9_beta_linux/trunk/ /usr/local/lasso9

3. Configure shell environment

a. Edit ~/.profile adding the following two lines

export LASSO9_HOME="/usr/local/lasso9"

export LD_LIBRARY_PATH="/usr/lib/jvm/java-6-openjdk/jre/lib/i386:/usr/lib/jvm/java-6-openjdk/jre/lib/i386/server:$LD_LIBRARY_PATH"

	$> source ~/.profile

c. Run installation script

$> cd "$LASSO9_HOME"/Installers
$> sudo chmod +x install_lasso9
$> sudo -E ./install_lasso9

	$> sudo chgrp -R admin "$LASSO9_HOME"
$> sudo chmod -R g+w "$LASSO9_HOME"

4. Start Lassoserver to verify as well

$> env LASSO9_PRINT_FAILURES=1 lassoserver

(This uses Control-C to stop it)

Configure Apache

   FastCgiExternalServer /lasso9       -host localhost:8999 -pass-header Authorization
   FastCgiExternalServer /lasso9direct -host localhost:8999 -pass-header Authorization

   ScriptAliasMatch  ^/lasso9/(.*)$   /lasso9/$1
   ScriptAliasMatch  ^(.*\.lasso9?)$  /lasso9direct$1


# disable mod_deflate for lassoapps
# (Keeps admin running quickly. Thanks to Jason Huck!)

	RemoveOutputFilter DEFLATE
	SetEnvIfNoCase Request_URI .*$ no-gzip dont-vary

2. Restart apache

$> sudo /etc/init.d/apache2 restart

3. If you get the "FastCgiExternalServer /lasso9: failed to resolve "localhost" to exactly one IP address" error, then edit /etc/hosts

Get rid of the localhost on this line

#::1     localhost ip6-localhost ip6-loopback

… so it should now look like this...

#::1     ip6-localhost ip6-loopback

try restarting apache per step 2

Configure MySQL Socket

(For some reason with localhost, this is where Lasso wants the socket and it won't connect via port)
1. Stop MySQL

$> sudo /etc/init.d/mysql stop

2. Edit /etc/mysql/my.cnf

• Find the three places with "/var/run/mysqld/mysqld.sock" change to "/tmp/mysql.sock"
• Find the line starting with "bind-address" and comment it out ("#bind-address")

3. Edit /etc/mysql/debian.cnf

• Find the two places with "/var/run/mysqld/mysqld.sock" change to "/tmp/mysql.sock"

4. Restart MySQL

$> sudo /etc/init.d/mysql start

Now you should be done / ready to go - starting lassoserver manually.
