django python-2.7

Gunicorn&x2B；Django+；Virtualenv+；初始d服务（CentOS）,django,python-2.7,virtualenv,centos6,gunicorn,Django,Python 2.7,Virtualenv,Centos6,Gunicorn,详情： OS = CentOS 6.6 python = 2.7.9 virtualenv = 12.1.1 gunicorn = 19.3.0 django-admin.py = 1.6.10 geonode = 2.4 我正在尝试使用Gunicorn在CentOS 6.6上添加一个django应用程序（geonode，）作为init.d服务。任何帮助都将不胜感激 CentOS 6.6的默认python版本为2.6，因此我安装了python 2.7.9作为备用版本： sudo wget ht

详情：

OS = CentOS 6.6
python = 2.7.9
virtualenv = 12.1.1
gunicorn = 19.3.0
django-admin.py = 1.6.10
geonode = 2.4

我正在尝试使用Gunicorn在CentOS 6.6上添加一个django应用程序（geonode，）作为init.d服务。任何帮助都将不胜感激

CentOS 6.6的默认python版本为2.6，因此我安装了python 2.7.9作为备用版本：

sudo wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz
sudo tar -xzf Python-2.7.9.tgz
cd Python-2.7.9
sudo ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
sudo make
sudo make altinstall

已安装的setuptools、pip和virtualenv：

su -
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-15.0.tar.gz
tar -xvf setuptools-15.0.tar.gz
cd setuptools-15.0
python2.7 setup.py install
cd ..
rm -fr setuptools-15.0*
curl https://raw.githubusercontent.com/pypa/pip/master/contrib/get-pip.py | python2.7 -
pip2.7 install virtualenv

已配置将运行django应用程序的服务帐户：

sudo mkdir -p /webapps/geonode_django/
sudo groupadd --system webapps
sudo useradd --system --gid webapps --shell /bin/bash --home /webapps/geonode_django geonode
sudo chown geonode /webapps/geonode_django/

git clone https://github.com/GeoNode/geonode.git
cd geonode
pip install -e . --log install-geonode.log

设置虚拟环境和已安装的python依赖项：

su -
su - geonode
virtualenv -p /usr/local/bin/python2.7 .
source bin/activate
export PYCURL_SSL_LIBRARY=nss
pip install pycurl
pip install urlgrabber
pip install numpy
pip install pillow
pip install pastescript
pip install psycopg2
pip install gunicorn
wget https://pypi.python.org/packages/source/G/GDAL/GDAL-1.11.2.tar.gz
tar -xvf GDAL-1.11.2.tar.gz
cd GDAL-1.11.2
python setup.py build_ext --include-dirs=/opt/gdal-1.11.2/include/
python setup.py install
cd ..
rm -fr GDAL-1.11.2*

克隆并安装了django应用程序：

sudo mkdir -p /webapps/geonode_django/
sudo groupadd --system webapps
sudo useradd --system --gid webapps --shell /bin/bash --home /webapps/geonode_django geonode
sudo chown geonode /webapps/geonode_django/

git clone https://github.com/GeoNode/geonode.git
cd geonode
pip install -e . --log install-geonode.log

执行所需的geonode（django应用程序）命令

创建了一个脚本以运行gunicorn：

mkdir /webapps/geonode_django/scripts
vim /webapps/geonode_django/scripts/gunicorn-app.sh

启动gunicorn-app.sh

#!/bin/bash
set -e
cd /webapps/geonode_django/geonode
source /webapps/geonode_django/bin/activate
exec /webapps/geonode_django/bin/gunicorn geonode.wsgi:application \
--workers=2 \
--bind=0.0.0.0:8000 \
--user=geonode --group=webapps --log-level=debug \
--log-file=/webapps/geonode_django/logs/gunicorn.log 2>>/webapps/geonode_django/logs/gunicorn.log

gunicorn-app.sh的结尾注意：脚本基于此处找到的脚本-

注意：我可以以root和geonode的身份成功运行该脚本，它会显示初始页面，但当我将其添加到init.d脚本并以“service”的形式运行时，结果如下：

[root@geonode_test ~]# curl localhost:8000
<html>
   <head>
     <title>Internal Server Error</title>
   </head>
   <body>
     <h1><p>Internal Server Error</p></h1>

   </body>
</html>

export GDAL_HOME=/opt/gdal-1.11.2
export GDAL_DATA=$GDAL_HOME/data
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$GDAL_HOME/lib
export PATH=$GDAL_HOME/bin:/usr/pgsql-9.3/bin:$PATH

注意：这是有效的，只是不作为服务以/etc/init.d/gunicorn start运行时ps aux | grep gunicorn的输出

到

exec/webapps/geonode\u django/bin/gunicorn测试：应用\

gunicorn的日志不是最有用的，出于挫折，我尝试了uwsgi，它立即显示了问题：

使用服务gunicorn start对其进行了测试。。。它是有效的。希望这对其他人有所帮助。

注意：selinux没有阻塞，netstat显示它在以/etc/init.d/gunicorn start和服务gunicorn start运行时正在侦听端口8000
