The packages will work on CentOS and RedHat Enterprise 5.x or 6.x, or Amazon Linux, with Apache httpd 2.2 or 2.4.
Installing a deployment environment on platforms that uses RPM packages is now even easier than ever.
Install the Yum repository of the WOCommunity like this:
sudo curl -o /etc/yum.repos.d/wocommunity.repo https://raw.github.com/wocommunity/wonder/master/Utilities/Linux/wocommunity.repo
Once it's done, you can use Yum to install wotaskd and JavaMonitor.
sudo yum install wotaskd; sudo yum install womonitor;
To install the module for Apache httpd 2.2, run:
sudo yum install woadaptor
for Apache httpd 2.4:
sudo yum install woadaptor-httpd24
If SELinux is enabled on your system, wotaskd won't be reachable due to its preventing Apache from opening TCP connections. If you're comfortable with allowing Apache to connect to any TCP ports (including external hosts), you can run the following:
sudo setsebool -P httpd_can_network_connect=1
Alternatively, Steven Klassen has written a blog post (Custom SELinux Port Access) that outlines how to create and install a wotaskd SELinux module that specifically allows connections to port 1085.
And you're done! When the packages are installed, the services are started automatically. JavaMonitor will be running on port 56789. Your Project Wonder applications goes into /opt/Local/Library/WebObjects/Applications.
If you wish to restart wotaskd or Monitor, startup scripts are located in /etc/init.d. You can use the service tool to stop or restart them:
sudo /sbin/service wotaskd stop sudo /sbin/service womonitor stop
(replace stop with restart to restart them in one step).
When Monitor is started, it will report to the console that is available at address like "ip-10-212-110-28" but that is the internal address of the Amazon server. The external address, which you must use, is available in the AWS console, and of the form "ec2-xx-vv-zz-ww.compute-1.amazonaws.com".
Don't forget to change the password in JavaMonitor after you made the installation!
The yum repositories for deployment artifacts is a little out of date, so these instructions are based on wonder source and compiling the adaptor on the target system.
$ sudo yum install httpd https-dev $ # get the latest wonder source $ git clone https://github.com/wocommunity/wonder.git $ cd wonder/Utilities/Adaptors $ # thanks to alextu for these commands to fix the make.config file $ # (from his docker recipe) $ sed -ri 's/ADAPTOR_OS = MACOS/ADAPTOR_OS = LINUX/g' make.config $ sed -ri 's/ADAPTORS = CGI Apache2.2/ADAPTORS = Apache2.4/g' make.config $ make $ # move the compiled module to the modules directory (check your apache config $ # but the default on CentOS7 is /usr/lib64/httpd/modules $ cp Apache2.4/mod_WebObjects.so /usr/lib64/httpd/modules/
The standard apache.conf (found in the wonder source at wonder/Utilities/Adaptors/Apache2.4/apache.conf) should work fine. Here are a couple of modifications that worked for me:
The authorization for Apache changed between 2.2 and 2.4. If you're used to "Allow from all" or "Deny from all" you should know that Apache 2.4 syntax has changed so this is how those allows/denies work now. This is a mostly permissive structure restricting some of the verbs that are not used (We have some configs that allow PUT, DELETE, PROPFIND, etc... but they don'tcall me "Little Paranoid Larry" for nothing.
WebObjectsAlias /cgi-bin/WebObjects <Location /cgi-bin/WebObjects/> <Limit GET POST OPTIONS > Require all granted </Limit> Require all denied </Location>
CentOS7 switched to using FirewallD from IP Tables. I've tried to understand firewalld and I'm actually digging it even though it's a big change from IP Tables. Useful info on Firewalld can be found at Linux firewalld information at Oracle or FirewallD at Fedora.
The cheat sheet commands that help get started are:
getting help on the command line:
checking the state of the firewall:
set a service to a zone for runtime (not persistent) :
set a service to a zone permanently:
setup specific ports (like for WO instances)
reload the configuration:
find out what services the zone thinks should be handled at runtime (or permanently) :
go nuts and specify rules to within an inch of their lives:
As is mentioned in https://wiki.wocommunity.org/display/documentation/Installing+a+deployment+environment+on+RedHat,+CentOS+or+Amazon+Linux,
you can open up apache to network connections using the command:
$ # make sure you have the policy utils (yum install policycoreutils-python) $ sudo setsebool -P httpd_can_network_connect=1
If you have additional problems with the SELinux configuration, check the context and ownership of files. More useful information on SELinux can be found at http://wiki.centos.org/HowTos/SELinux.
