5 If you are using RedHat Enterprise Linux, CentOS or Amazon Linux, stop right there! We now have RPM packages for CentOS and RedHat 5.x/6.x, and Amazon Linux. [[Read the following instructions>>doc:documentation.Home.Deployment.Platforms.Installing a deployment environment on RedHat, CentOS or Amazon Linux.WebHome]] instead of this document.
6
7 Guess what? If you are using Debian or Ubuntu, [[packages>>doc:documentation.Home.Deployment.Platforms.Installing a deployment environment on Debian or Ubuntu releases from 2008 to 2016.WebHome]] are also available for your platform (although not yet for Xenial)!
8 {{/warning}}

10 === Install Sun Java JDK ===
11
12 ~1. You should install a [[Sun/Oracle Java SDK>>url:http://www.oracle.com/technetwork/java/javase/downloads/index.html||shape="rect"]]. Use Oracle's [[installation instructions>>url:http://www.oracle.com/technetwork/java/javase/index-137561.html#linux||shape="rect"]]. Choose the appropriate 32-bit or 64-bit Linux installer, for example jdk-6u27-linux-x64-rpm.bin, and install it.
13
14 {{warning}}
15 Make sure to install the correct "bit" version for the OS, e.g. install 64 bit JVM on a 64 bit installation, and a 32 bit JVM on a 32 bit installation! To find that information, do:
16
17 {{code}}
18 uname -p
19 {{/code}}
20
21 If the response is //x86_64//, it's a 64 bit system. If the response is //i386// or //i686//, it's a 32 bit system.
22 {{/warning}}
23
24 Creating symbolic links as follows is useful (alternatively use the 'alternatives' command to manage JVMs):
25
26 {{code}}
27 ln -s /usr/java/jdk1.6.0_27 /usr/java/jdk1.6
28 ln -s /usr/java/jdk1.6/bin/java /usr/bin/java
29 {{/code}}
30
31 and you need to change your path in your bash profile (_~~/.bash_profile) to have this path :
32
33 {{code}}
34 PATH=$PATH:/usr/java/jdk1.6/bin:$HOME/bin
35 {{/code}}
36
37 === Install the WebObjects frameworks (Optional) ===
38
39 {{info}}
40 If you embed the frameworks into your applications, you don't need to install the core frameworks on the deployment system. Install them only if your applications don't have the frameworks inside their bundles.
41 {{/info}}
42
43 2. Get the WebObjects installer from the wocommunity's Web site :
44
45 {{code}}
46 curl -C - -O https://jenkins.wocommunity.org/job/WOInstaller/lastSuccessfulBuild/artifact/Utilities/WOInstall/WOInstaller.jar
47
48 OR
49
50 wget https://jenkins.wocommunity.org/job/WOInstaller/lastSuccessfulBuild/artifact/Utilities/WOInstall/WOInstaller.jar
51 {{/code}}
52
53 and install it like this :
54
55
56 [[https:~~/~~/download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/Mac_OS_X/downloads/061-4634.20080915.3ijd0/WebObjects543.dmg>>url:https://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/Mac_OS_X/downloads/061-4634.20080915.3ijd0/WebObjects543.dmg||shape="rect"]]\\
57
58 {{{ wget sudo java -jar WOInstaller.jar dev54 /opt}}}
59
60 You may see an error as the command above finishes, but WO may still be installed.
61
62 This command below is what you could do if you did not need the dmg above. Unfortunately there is a bug having to do with downloading via HTTPS and you do not get the WebObjects543.dmg automatically and you need the command above.

71 {{{ sudo /usr/java/latest/bin/java -jar WOInstaller.jar 5.4.3 /optWebObjects frameworks are now installed in }}}

78 drwxr-xr-x 3 root root 4096 Nov 9 08:20 Local
79 {{/code}}
80
81 === Creating the //appserver// user and starting wotaskd/JavaMonitor ===
82
83 To follow the conventions from Mac OS X, we will create two users to run wotaskd and Monitor under this user :
84
85 {{code}}
86 sudo groupadd appserveradm
87 sudo useradd -g appserveradm appserver
88 {{/code}}
89
90 Edit the bash profile of the appserver
91
92 {{code}}
93 # sudo su - appserver
94 % vi .bash_profile
95 {{/code}}
96
97 and add this line :
98
99 {{code}}
100 export NEXT_ROOT=/opt
101 {{/code}}
102
103 and run it manually in your current shell :
104
105 {{code}}
106 [appserver@ ~]$ . .bash_profile
107 {{/code}}
108
109 3. Next, we need to install the Wonder version **wotaskd** and **JavaMonitor**.
110
111 {{code}}
112 $ mkdir -p /opt/Local/Library/WebObjects/JavaApplications
113 $ cd /opt/Local/Library/WebObjects/JavaApplications
114 $ wget https://jenkins.wocommunity.org/job/Wonder7/lastSuccessfulBuild/artifact/Root/Roots/wotaskd.tar.gz
115 $ tar zpxf wotaskd.tar.gz
116 $ rm wotaskd.tar.gz
117 $ wget https://jenkins.wocommunity.org/job/Wonder7/lastSuccessfulBuild/artifact/Root/Roots/JavaMonitor.tar.gz
118 $ tar zpxf JavaMonitor.tar.gz
119 $ rm JavaMonitor.tar.gz
120 {{/code}}
121
122 4. Now we need to change some permissions:
123
124 {{code}}
125 sudo chown -R appserver:appserveradm /opt/Local
126 sudo chown -R appserver:appserveradm /opt/Library
127 {{/code}}
128
129 5. Now we can start wotask and Monitor
130
131 {{code}}
132 [root@ ~]# sudo su - appserver
133 {{/code}}
134
135 You can start wotaskd and Monitor, manually, to make sure that they run without any problems :
136
137 {{code}}
138 [appserver@ ~]$ $NEXT_ROOT/Local/Library/WebObjects/JavaApplications/wotaskd.woa/wotaskd &
139 [appserver@ ~]$ $NEXT_ROOT/Local/Library/WebObjects/JavaApplications/JavaMonitor.woa/JavaMonitor -WOPort 56789 &
140 {{/code}}
141
142 === Apache ===
143
144 //(Should info on properly installing and configuring Apache be its own page? Is it its own page somewhere else already? -rrk)//
145
146 If your Linux installation don't already have Apache httpd running or installed, you need to install it:
147
148 For Ubuntu distributions :
149
150 {{code}}
151 sudo apt-get install apache2 apache2.2-common apache2-mpm-prefork apache2-utils apache2-threaded-dev ssl-cert
152 {{/code}}
153
154 On that system the relevant command names are //apache2ctl// and //apxs2//, and the document root is ///var/www// (not ///usr/local/apache/htdocs// as in the example below).
155
156 (you will need httpd-devel and gcc)
157
158 For CentOS, RedHat or Fedora distributions :
159
160 {{code}}
161 I found on AWS for apache 2.4 I had to change the yum to: yum install httpd24 httpd24-devel   yum install httpd mod_ssl httpd-devel chkconfig httpd on /etc/init.d/httpd start
162 {{/code}}
163
164 .. default install location is then /etc/httpd
165
166 === HTTP Adaptor ===
167
168 First, check if a pre-built module already exists at [[wocommunity.org>>url:http://wocommunity.org/documents/tools/mod_WebObjects/||shape="rect"]]. If you are running CentOS 6.x, you can use the module for CentOS 5.5, it works fine.
169
170 Once you have downloaded the module, you can install it with:
171
172 {{code}}
173 sudo apxs -i -a -n WebObjects mod_WebObjects.so
174 {{/code}}
175
176 If you can't find a adaptor for your Linux platform, you [[will have to build it>>doc:documentation.Home.Deployment.Compiling the HTTP adaptor on Linux.WebHome]]
177
178 === Apache Configuration ===
179
180 Instead of copying the //WebObjects// directory, you can use a alias to point to the folder inside NEXT_ROOT. In your Apache configuration, add something like :
181
182 {{code}}
183 Alias /WebObjects "/opt/Local/Library/WebServer/Documents/WebObjects"
184 {{/code}}
185
186 and add a directive to allow fetching files in this directory:
187
188 {{code}}
189 <Directory "/opt/Local/Library/WebServer/Documents/WebObjects"> AllowOverride All Order allow,deny Allow from all </Directory>
190 {{/code}}
191
192 Or (depending on your Apache configuration) you could use a symbolic link.
193
194 You also need, as explained by the adaptor's README file, to add this directive in //httpd.conf// :
195
196 {{code}}
197 <LocationMatch /apps/WebObjects/.*> Order allow,deny Allow from all </LocationMatch>
198 {{/code}}
199
200 If you don't add it, you will get 403s (Forbidden) HTTP errors.
201
202 If you want to keep ///cgi-bin/WebObjects// as the base URL, you will need to remove a line in //httpd.conf//. Find the line that starts with //ScriptAlias /cgi-bin// and comment it out, or else Apache will try to find a //WebObjects// CGI in ///cgi-bin// instead of loading the adaptor from the Apache module.
203
204 And edit ///usr/local/apache/conf/extra/webobjects.conf// to comment the //LoadModule WebObjects_module// line. You can also change the //WebObjectsAlias// property, in my case I use ///apps/WebObjects//. Last step : add the following line in httpd.conf (near the end):
205
206 {{code}}
207 Include conf/extra/webobjects.conf
208 {{/code}}
209
210 Check for any errors with //apachectl configtest//, and if everything's ok, you are good to go. You can install your first app, don't forget that your app must be accessible by the //appserver// user or the //appserveradm// group. If your app don't start or if Monitor complains about a path, it might be a permission problem.
211
212 Jerome Chan told me that you can check if the Apache module is loaded by doing this :
213
214 {{code}}
215 /usr/local/apache/bin/apachectl -M
216 {{/code}}
217
218 On my installation on OpenSuse 11.1, I had to change the path to the lib64 directory where Apache contains the modules.
219
220 {{code}}
221 LoadModule WebObjects_module /usr/lib64/apache2/mod_WebObjects.so
222 {{/code}}
223
224 === Auto Start WOTaskd and WOMonitor ===
225
226 One last thing, you need a init script to start wotaskd and Monitor at boot time.
227
228 The scripts are [[available>>url:https://github.com/wocommunity/wonder/tree/integration/Utilities/Linux/StartupScripts/RedHat||shape="rect"]] on GitHub. Grab the two files (//womonitor// and //wotaskd//) and copy them into the proper directory.
229
230 You will be able to see where the services files should go by searching for others.
231
232 {{code}}
233 find /etc /lib -name \*.service
234 {{/code}}
235
236 Once a wotaskd.service and womonitor.servcie file are in the proper location, you can start them:
237
238 {{code}}
239 sudo service start wotaskd
240 sudo service start womonitor
241 {{/code}}
242
243 (% class="auto-cursor-target" %)
244 You should be deploying as the user "appserver" and, if you have done this, make sure that all files and directories referred to in the service files exist and that the permissions are as they should be and that they are owned by or accessible to the appserver user. All files must be readable, all directories must be readable and executable and scripts must the executable. Make sure to check log file locations as well.
245
246 (% class="auto-cursor-target" %)
247 Any errors in these files may make the service fail to start in non-obvious ways. The resulting error messages may not be helpful. The best strategy is to be very careful with the contents of the files. An example service file is below. Running "systemctl status" on the services and carefully examining everything in the output may help you with deployment problems.
248
249 (% class="auto-cursor-target" %)
250 Enabling the services will ensure that the services restart after a reboot.
251
252 {{code}}
253 sudo service enable wotaskd
254 sudo service enable womonitor
255 {{/code}}

279 === Problems with Application Responding to WOMonitor/WOTaskd ===
280
281 If your Linux server is a virtual machine or if it has multiple IP addresses, you may find that clicking 'Stop' in WOMonitor has no effect on instances, or that the applications never start (the level just go up and down non-stop). This can usually be solved for all Wonder-based applications running on hosts with such a problem by simply creating the following file (known as the 'Machine Properties' file in Wonder's ERXProperties):
282
283 {{code}}
284 /etc/WebObjects/Properties
285 {{/code}}
286
287 And inside that file, add an array property that defines all the IP addresses assigned to your host, for example:
288
289 {{code}}
290 er.extensions.WOHostUtilities.localhostips=(192.168.3.168,192.168.1.168)
291 {{/code}}
292
293 (% class="auto-cursor-target" %)
294 \\

297 To learn more, see the class named WOHostUtilities in ERExtensions framework
298 {{/info}}
299
300 SELinux
301
302 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:
303
304 {{code}}
305 sudo setsebool -P httpd_can_network_connect=1
306 {{/code}}
307
308 Alternatively, [[Steven Klassen>>url:http://www.mrxinu.com/||shape="rect"]] has written a blog post ([[Custom SELinux Port Access>>url:http://www.mrxinu.com/2013/06/07/custom-selinux-port-access/||shape="rect"]]) that outlines how to create and install a wotaskd SELinux module that specifically allows connections to port 1085.
309
310 {{warning}}
311 Be aware that SELinux is enabled by default on CentOS 6.x, you will need to either call the //setsebool// command or to [[disable SELinux>>url:http://www.how2centos.com/disable-selinux-centos-6/||shape="rect"]]
312 {{/warning}}
