django+centos+cx_Oracle開發環境搭建

Linux設置固定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

重啓配置文件使之生效

/etc/init.d/network restart

pip 安裝

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

django 安裝

略

Oracle client 安裝

./centos_cx_Oracle.sh 文件以下:

#!/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

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

pip install cx_Oracle

 
 
 
 
 

而後讓新環境生效 source ~/.bash_profile

cx_Oracle 安裝

error: command 'gcc' failed with exit status 1
yum -y install gcc-* libxml2-devel python-devel mysql-devel

若是centos默認源被牆壁

打開文件/etc/resolv.conf在其中添加：
nameserver 8.8.8.8
而後重啓網卡：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 = 數據庫IP)(PORT = 1521))  
)  
(CONNECT_DATA =  
(SID = 數據庫)  
)  
)  

添加如下內容到 /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;

而後讓新環境生效 source /etc/profile

而後再安裝PIL庫

用pil產生驗證碼出現：ImportError: The _imagingft C module is not installed
這個是因爲PIL沒有編譯freetype致使的

須要先安裝jpeg庫

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

而後再安裝PIL庫

讓PIL支持freetype的方法
一、安裝freetype開發庫
yum install freetype-devel

二、下載源代碼
http://effbot.org/downloads/Imaging-1.1.7.tar.gz

三、修改setup.py文件

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

四、查看支持項
python setup.py build_ext -i
--- FREETYPE2 support available 注意這一項

五、編譯安裝
python setup.py install
若上面的設置都失敗，則只能拿出下面的殺手鐗：

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

當現下面的提示時，則說明安裝成功了：

--------------------------------------------------------------------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--------------------------------------------------------------------

DjangoCaptcha 安裝
