django+centos+cx_Oracle开发环境搭建

摘要：设置固定重启配置文件使之生效安装安装略安装文件如下然后让新环境生效安装如果默认源被墙壁打开文件在其中添加然后重启网卡使用命令数据库数据库添加以下内容到然后让新环境

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

./centos_cx_Oracle.sh 文件如下:

# 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

pip install cx_Oracle

然后让新环境生效 source ~/.bash_profile

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

</>复制代码 
 
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

</>复制代码 
 
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

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

</>复制代码 
wget http://www.ijg.org/files/jpegsrc.v7.tar.gz
tar -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

</>复制代码 
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：

</>复制代码 
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--------------------------------------------------------------------

用于验证码生成

pip install xlwt

pip install unipath

添加 127.0.0.1 主机名称 到 /etc/hosts

iptables -F

settings文件修改:

</>复制代码 
DEBUG = True
INTERNAL_IPS = ("127.0.0.1", "192.168.1.100")

</>复制代码 
/sbin/service crond start
/sbin/service crond stop
/sbin/service crond restart
/sbin/service crond reload
