django+centos+cx_Oracle开发环境搭建

不 断 前 行，方 可 不 被 淘 汰

Linux设置固定IP

vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.0.116
NETMASK=255.255.0.0
GATEWAY=192.168.0.1
ONBOOT=yes
TYPE=Ethernet

重启配置文件使之生效

/etc/init.d/network restart

pip 安装

tar -xzvf pip-1.5.4.tar.gz
pip install xxx -i http://pypi.douban.com/simple

django 安装

略

Oracle client 安装

./centos_cx_Oracle.sh 文件如下:

#!/bin/bash

# INSTALL ORACLE INSTANT CLIENT 
##################################

# NOTE: Oracle requires at least 1176 MB of swap (or something around there).
# If you are using CentOS in a VMWare VM, there's a good chance that you don't have enough by default.
# If this describes you and you need to add more swap, see the
# "Adding a Swap File to a CentOS System" section, here:
# http://www.techotopia.com/index.php/Adding_and_Managing_CentOS_Swap_Space

# Install basic dependencies
sudo yum -y install libaio bc flex

echo "Now go get some the following two RPMs ..."
echo "- basic: oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm"
echo "- SDK/devel: oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm"
echo "... from this URL: http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html"
echo "WARNING: It's pretty annoying, they make you sign up for an Oracle account, etc."
echo 'I will assume you have put these two files are into ~/Downloads'
echo "Press any key once you're ready" && read -n 1 -s

sudo rpm -ivh ~/Downloads/oracle-instantclient11.2-basic-*
sudo rpm -ivh ~/Downloads/oracle-instantclient11.2-devel-*
sudo rpm -ivh ~/Downloads/oracle-instantclient11.2-sqlplus-*

# SET ENVIRONMENT VARIABLES 
##############################

# Source for this section: http://cx-oracle.sourceforge.net/BUILD.txt

# (SIDENOTE: I had to alter it by doing some digging around for where the Oracle RPMs really installed to;
# if you ever need to do this, do a command like this:
#     rpm -qlp )

echo '# Convoluted undocumented Oracle bullshit.' >> $HOME/.bashrc
echo 'export ORACLE_VERSION="11.2"' >> $HOME/.bashrc
echo 'export ORACLE_HOME="/usr/lib/oracle/$ORACLE_VERSION/client64/"' >> $HOME/.bashrc
echo 'export PATH=$PATH:"$ORACLE_HOME/bin"' >> $HOME/.bashrc
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"$ORACLE_HOME/lib"' >> $HOME/.bashrc
. $HOME/.bashrc

# INSTALL cx_Oracle #
#####################

pip install cx_Oracle

然后让新环境生效 source ~/.bash_profile

cx_Oracle 安装

error: command 'gcc' failed with exit status 1

yum -y install gcc-* libxml2-devel python-devel mysql-devel

如果centos默认源被墙壁

打开文件/etc/resolv.conf在其中添加：
nameserver 8.8.8.8
然后重启网卡：使用命令: service network restart
/usr/lib/oracle/11.2/client64/network/admin/tnsnames.ora

 x =  
(DESCRIPTION =   
(ADDRESS_LIST =  
(ADDRESS = (PROTOCOL = TCP)(HOST = 数据库IP)(PORT = 1521))  
)  
(CONNECT_DATA =  
(SID = 数据库)  
)  
)  

添加以下内容到 /etc/profile

export ORACLE_HOME=/usr/lib/oracle/11.2/client64  
export TNS_ADMIN=/usr/lib/oracle/11.2/client64/network/  admin
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/lib
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib:/usr/local/lib;

然后让新环境生效 source /etc/profile

然后再安装PIL库

用pil产生验证码出现：ImportError: The _imagingft C module is not installed

这个是由于PIL没有编译freetype导致的

需要先安装jpeg库

wget http://www.ijg.org/files/jpegsrc.v7.tar.gztar -zxvf jpegsrc.v7.
tar.gz
cd jpeg-7
CC="gcc -arch x86_64"./configure --enable-shared --enable-static
make
make install

然后再安装PIL库

让PIL支持freetype的方法

1、安装freetype开发库
yum install freetype-devel

2、下载源代码
http://effbot.org/downloads/Imaging-1.1.7.tar.gz

3、修改setup.py文件

JPEG_ROOT = libinclude("/usr/local")
FREETYPE_ROOT = '/usr/lib64','/usr/include/freetype2/freetype'

4、查看支持项
python setup.py build_ext -i
--- FREETYPE2 support available 注意这一项

5、编译安装
python setup.py install
若上面的设置都失败，则只能拿出下面的杀手锏：

sudo apt-get build-dep python-imaging
sudo ln -s /usr/lib/`uname -i`-linux-gnu/libfreetype.
so /usr/lib/sudo ln -s /usr/lib/`uname -i`-linux-gnu/libjpeg.so /usr/lib/sudo ln -s /usr/lib/`uname -i`-linux-gnu/libz.so /usr/lib/
pip install -U PIL

当现下面的提示时，则说明安装成功了：

--------------------------------------------------------------------PIL 1.1.7 SETUP SUMMARY--------------------------------------------------------------------version 1.1.7platform linux2 2.7.3 (default, Apr 10 2012, 22:21:37) [GCC 4.6.3]----------------------------------------------------------------------- TKINTER support available--- JPEG support available--- ZLIB (PNG/ZIP) support available--- FREETYPE2 support available*** LITTLECMS support not available--------------------------------------------------------------------

Django Captcha 安装

用于验证码生成

xlwt 安装

pip install xlwt

unipath 安装

pip install unipath

ORA-21561: OID generation failed

添加 127.0.0.1 主机名称 到 /etc/hosts

关闭防火墙

iptables -F

django 测试

settings文件修改:

DEBUG = True
INTERNAL_IPS = ('127.0.0.1', '192.168.1.100')

cron服务

/sbin/service crond start/sbin/service crond stop
/sbin/service crond restart
/sbin/service crond reload
