Welcome to my page on installing EWD. I am doing this on Ubuntu. If you do this on a Red Hat like system, you have to adapt the instructions.

Prerequisites

  • Latest Version of GT.M installed
  • VISTA installed

Install Git and download the Git Repos of EWD and Node.js

I make my own directory called src or svn or whatever and put all the source code in it. 

sudo apt-get install git-core				; Get Git
git clone git://github.com/robtweed/EWD.git		; Get EWD
git clone git://github.com/joyent/node.git		; Get Node.js
sudo apt-get install libssl-dev

Install Node.js & NPM

I install node per the Node.js wiki in my home directory and then add it to my path. You may have other ideas. 

# Install Node
cd node  # cd to the git directory you downloaded above
export JOBS=2 # optional, sets number of parallel commands.
mkdir ~/local
./configure --prefix=$HOME/local/node
make
make install
export PATH=$HOME/local/node/bin:$PATH (& put in .bashrc)

# Install NPM
sudo apt-get install curl
curl http://npmjs.org/install.sh | sh

Install and Set-up mgwsi

MGWSI is the tcp listener on GT.M that listens for apache requests. Make a routine directory that will be part of the $gtmroutines add add that directory to your $gtmroutines. (Or you could just use a directory already in the existing gtmroutines.) Here's my GT.M env set-up script, for example. I am running in UTF-8 mode, so you will see extra lines that have to do with that. 

#/bin/bash
cd ~/pocn-moh
export gtm_dist=/opt/fis-gtm/V5.4-002A/utf8/
export gtmroutines="uo(routines svn/BMX ewdroutines) $gtm_dist"
export gtmgbldir=mumps.gld
export PATH=$PATH:$gtm_dist
export gtm_chset=utf-8
export gtm_icu_version=4.2
export gtm_badchar=0
export gtm_principle_editing="EDITING"

Copy the ZMGWSI routines from EWD's m_apache directory to your routines folder. 

cp svn/EWD/m_apache/*.m ewdroutines/

Verify that the routines are found by GT.M: 

sam@sam-desktop:~/pocn-moh$ mumps -dir

GTM>d ^%RD

Routine directory
Routine: %ZM*
%ZMGWSI   %ZMGWSIS  
Total of 2 routines.

Run the program now to make sure it compiles properly. 

sam@sam-desktop:~/pocn-moh$ mumps -r INETD^%ZMGWSIS
%GTM-I-CTRLC, CTRL_C encountered

GTM>ZSHOW
CHILD3+5^%ZMGWSIS    (Direct mode) 
XINETD+2^%ZMGWSIS

GTM>H

Then make a bash script to call it: 

sam@sam-desktop:~/pocn-moh$ cat mgwsi-rpcproc 
#!/bin/bash
cd /home/sam/pocn-moh
source ./run_utf8
date>>rpc_log.log
$gtm_dist/mumps -run INETD^%ZMGWSIS 2>> rpc_log.log
exit 0

# Make it executable
sam@sam-desktop:~/pocn-moh$ chmod +x mgwsi-rpcproc 

# Run it
sam@sam-desktop:~/pocn-moh$ ./mgwsi-rpcproc 

GTM>zshow
CHILD3+5^%ZMGWSIS    (Direct mode) 
XINETD+2^%ZMGWSIS

GTM>h

Now we put it as a xinetd service 

# Create the following line in configuration file: /etc/services
mgwsi           7041/tcp                # Service for MGWSI clients

# Create Xined script that calls mgwsi-rpcproc
sudo cat mgwsi_pocn-moh_7041
service mgwsi-pocn-moh-7041
        {
        disable	= no
        port = 7041
        socket_type = stream
        protocol = tcp
        user = sam
        server = /bin/bash
        groups = yes
        server_args = /home/sam/pocn-moh/mgwsi-rpcproc
        type = UNLISTED
        wait = no
        }

Now we test it by putting xinetd in debug mode and then telneting to the port. 

sam@sam-desktop:/etc/xinetd.d$ sudo xinetd -d &
[2] 10521
...
Service configuration: mgwsi-pocn-moh-7041
	id = mgwsi-pocn-moh-7041
	flags = IPv4
	type = UNLISTED
	socket_type = stream
	Protocol (name,number) = (tcp,6)
	port = 7041
	wait = no
	user = 1000
	Groups = yes
	PER_SOURCE = -1
	Bind = All addresses.
	Server = /bin/bash
	Server argv = bash /home/sam/pocn-moh/mgwsi-rpcproc
	Only from: All sites
	No access: No blocked sites
	No logging

Once you are sure it works, foreground your xinetd process and kill it using Ctrl-C.

Setting up m_apache

First, make sure that m_apache is the right architecture for your machine. If not, you need to compile the m_apache.c file. The compilation instructions are from the source. Also, Mike Clayton's 64 bit installers for EWD provide the m_apache22 file in 64 bit format which you can extract from the .deb file. 

sam@sam-desktop:~/pocn-moh/svn/EWD/m_apache$ file m_apache22.so 
m_apache22.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped

Copy to the lib folder of apache modules: in Ubuntu: /usr/lib/apache2/modules 

sudo cp m_apache22.so /usr/lib/apache2/modules/

Configure your apache so that it will route all pages in a specific location to Mumps. Make sure to get your gld file correctly. I edited my /etc/apache2/sites-available/default to have these lines: 

    LoadModule m_apache_module /usr/lib/apache2/modules/m_apache22.so
    <Location /ewd>
        SetEnv MGWSI_PORT 7041
        SetEnv MGWSI_M_UCI /home/sam/pocn-moh/mumps.gld
        SetEnv MGWSI_M_FUNCTION runPage^%zewdGTMRuntime
    </Location>

Restart apache and make sure there aren't any errors. 

sam@sam-desktop:/etc/apache2/sites-available$ sudo service apache2 restart
 * Restarting web server apache2                                                                                                          apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
 ... waiting .apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
                                                                                                                                   [ OK ]

Test M apache. In a web browser, navigate to http://localhost/ewd/index.mgwsi. You should get an EWD Error Page. If you get an apache error message, something is wrong.

SELinux and Apache to MGWSI

If you do get an apache Service Unavailable message, it could be due to SELinux.

Review /var/log/audit/audit.log. See if there is a AVC type message like this: 

type=AVC msg=audit(1317316775.606:57870): avc:  denied  { name_connect } for  pid=15027 comm="httpd" dest=7041 scontext=unconfined_u:system_r:httpd_t:s0 tcontext=system_u:object_r:port_t:s0 tclass=tcp_socket

If you see something like this, you need to tell SELinux the following: 

semanage port -a -t http_port_t -p tcp 7041

Install EWD M Files

Copy the EWD Mumps files to a GT.M Mumps directory. They are all in the root of the repo. 

sam@sam-desktop:~/pocn-moh/svn$ cp EWD/*.m ../ewdroutines/

Install Resources

You need to install a bunch of files under /var/www:
# Copy iwd from the root directory to /var/www/
sudo cp -r iwd /var/www/

# Copy the resources files from the ewdMgr/resourceFiles directory to /var/www/resources (which you need to make)
sudo mkdir -p /var/www/resources
sudo chmod 777 /var/www/resources/
sudo cp ewdMgr/resourceFiles/* /var/www/resources

# Get the YUI library and install it.
wget http://yui.zenfs.com/releases/yui2/yui_2.6.0r2.zip
sudo unzip yui_2.6.0r2.zip -d /var/www/
sudo chmod 777 /var/www/yui/

Install EWD Applications

# Make a directory for applications
sam@sam-desktop:~/pocn-moh$ mkdir ewdapps

# Copy the ewdMgr and iwd to that directory
cp -r ewdMgr/ ../../ewdapps/
cp -r iWDApps/ ../../ewdapps/

Configure EWD for the First Run

There are many bugs in this area, so make sure to read below so you know what you are in for before doing any of these steps. 

GTM>KILL ^zewd

GTM>D compileAll^%zewdAPI("ewdMgr")

Installing/Configuring Enterprise Web Developer (Build 790)

Note: hit Esc to go back at any point


Application Root Path (/usr/ewdapps): /home/sam/pocn-moh/ewdapps
Routine Path (/usr/local/gtm/ewd/): /home/sam/pocn-moh/ewdroutines/

Javascript and CSS File URL Path (/resources/): /resources/

Enterprise Web Developer (Build 790) is configured and ready for use

EWD First Run Bugs

  • _zewdDocumentation2.m contains invalid Unicode characters. I cleaned it up using iconv.
iconv -fUTF8 -tUTF8 -c _zewdDocumentation2.m -o _zewdDocumentation2.m
  • EWD expects to be able to write to /var/www/resources. I put that in the instructions for that section.
  • For some reason, EWD switches the routine path the first time it connects from the web. Why??? So you have to fix it manually. AND REMEMBER TO PUT A TRAILING SLASH. THAT ONE CAUGHT ME FOR A WHILE!!!
S ^zewd("config","routinePath","gtm")="/home/sam/pocn-moh/ewdroutines/"
  • Issue of compiling applications with subdirectories. Where is it supposed to output? Update: Rob says ignore for now. Here's an example:
GTM>d compileAll^%zewdAPI("iWDApps")
