14   This documentation was created thanks to Guillaume Sueur from Neogeo Technologies which took time to test
15   installing the ZOO-Kernel on a CentOS 5.5 environment.
16
17Requirements
18------------
19
20Install some standard tools to be able to run ZOO-Kernel on your platform :
21
22::
23
24  yum install apache2
25  yum install build-essentials
26  yum install gcc-c++
27  yum install zlib-devel
28  yum install libxml2-devel
29  yum install bison
30  yum install openssl
31  yum install python-devel
32  yum install subversion
33
34Compile then install FastCGI library from source
35
36::
37
38  wget http://www.fastcgi.com/dist/fcgi.tar.gz
39  tar xzf fcgi-2.4.0.tar.gz
40  ./configure
41  make
42  make install
43  echo /usr/local/lib >> /etc/ld.so.conf.d/local.conf
44  ldconfig
45
46Compile then install the autoconf tools :
47
48::
49
50  wget http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz
51  tar xzf autoconf-latest.tar.gz
52  ./configure --prefix=/usr
53  make
54  make install
55
56Compile then install the flex tool :
57
58::
59
60  wget http://downloads.sourceforge.net/project/flex/flex/flex-2.5.35/flex-2.5.35.tar.gz?r=http%3A%2F%2Fflex.sourceforge.net%2F&ts=1292529005&use_mirror=switch
61  tar xzf flex-2.5.35.tar.gz
62  cd flex-2.5.35
63  ./configure --prefix=/usr
64  make
65  make install
66
67Using the curl provided in the CentOS distribution will produce a ZOO-Kernel unable to run any
68Service. Indeed, some segmentation faults occur when trying to run ``Execute`` requests on the ZOO-Kernel,
69compiling the ZOO-Kernel setting ``USE_GDB`` flag in the ``CFLAGS`` of your ``Makefile`` will let you run
70ZOO-Kernel from gdb and be able to get more information on what is going wrong with your ZOO-Kernel.
71Doing this we can figure out that code on `line 173 <http://zoo-project.org/trac/browser/trunk/zoo-kernel/ulinet.c#L173>`__
72and `line 175 <http://zoo-project.org/trac/browser/trunk/zoo-kernel/ulinet.c#L175>`__ have to be commented in the
73``ulinet.c`` file to get a ZOO-Kernel working using the curl available in CentOS (curl version 7.15.5).
74If you don't apply the modification, you will get an error from a gdb session pointing
75segfault in ``Curl_cookie_clearall``.
76
77You can optionally compile then install curl from source :
78
79::
80
81  wget http://curl.haxx.se/download/curl-7.21.3.tar.bz2
82  tar xjf curl-7.21.3.tar.bz2
83  cd curl-7.21.3
84  ./configure --prefix=/usr
85  make
86  make install
87
88Compile then install Python :
89
90::
91 
92  wget http://www.python.org/ftp/python/2.6.6/Python-2.6.6.tar.bz2
93  tar xjf Python-2.6.6.tar.bz2
94  cd Python-2.6.6
95  ./configure
96  make
97  make install
98
99Compile then install your own GDAL library :
100
101::
102
103  wget http://download.osgeo.org/gdal/gdal-1.7.3.tar.gz
104  tar xzf gdal-1.7.3.tar.gz
105  cd gdal-1.7.3
106  ./configure  # add your options here
107  make
108  make install
109
110Install the Sun JAVA SDK into ``/usr/share`` then use the following command to ensure that the ``libjvm.so``
111will be found at runtime from any context.
112
113::
114
115  echo /usr/share/java-1.6.0-openjdk-1.6.0.0/jre/lib/i386/client/ >> /etc/ld.so.conf.d/jvm.conf
116  ldconfig
117
118Compile ZOO-Kernel and ZOO-Services
119-----------------------------------
120
121Compile then install ZOO-Kernel and your first ZOO-Services.
122
123First of all, compile the cgic library providen in the SVN source tree:
124
125::
126
127  svn co http://svn.zoo-project.org/svn/trunk zoo-project
128  cd zoo-project/thirds/cgic206
129  make
130
131Compile then install ZOO-Kernel.
132
133::
134
135  cd ../../zoo-kernel
136  ./configure --with-java=/usr/share/jdk1.6.0_23/ --with-python
137  make zoo_loader.cgi
138  cp main.cfg /var/www/cgi-bin/
139  cp  zoo_loader.cgi /var/www/cgi-bin/
140
141Compile then deploy your first ZOO-ServicesProviders (simple HelloPy, line 1 and 2, and the OGR base-vect-ops
142ServiceProvider, line 3 to 6):
143
144::
145
146  cp ../zoo-services/hello-py/cgi-env/*.zcfg /var/www/cgi-bin/
147  cp ../zoo-services/hello-py/test_service.py /var/www/cgi-bin/
148  cd ../ogr/base-vect-ops/
149  make
150  cp ./cgi-env/* /var/www/cgi-bin/
151  vi /var/www/cgi-bin/main.cfg --> set your own informations here
152
153To ensure that the ``libjvm.so`` will be found from apache, please restart it :
154
155::
156
157  /etc/init.d/httpd restart
158
159Testing your ZOO-Kernel
160-----------------------
161
162Test your ZOO-Kernel from command line:
163
164::
165
166  cd /var/www/cgi-bin
167  ./zoo_loader.cgi "request=Execute&service=WPS&version=1.0.0&Identifier=HelloPy&DataInputs=a=Djay"
168  ./zoo_loader.cgi "request=Execute&service=WPS&version=1.0.0&Identifier=Buffer&DataInputs=BufferDistance=1@datat
