经过各种坑之后centos+ uwsgi + nginx +django 终于配好了

https://pypi.python.org/pypi/setuptools#downloads

https://www.python.org/ftp/python/

开机 加入 uwsgi nginx 自启动

echo "/etc/init.d/nginx restart" >>/etc/rc.local 

echo "/usr/bin/setsid /data/soft_ware/uwsgi-1.9.6/uwsgi /data/soft_ware/s10day11/demo.ini " >>/etc/rc.local 

setsid 是后台挂起不受hungup 信号的影响。 进程号为1 与init相同

一 centos python是2.6 版本所以我们需要 装python2.7.9  请看之前的博客

查看python的版本

#python  -V
Python 2.6.6

1.下载Python-2.7.3

#wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2

附带 3.5.1 https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tar.xz
2.解压

#tar -jxvf Python-2.7.3.tar.bz2

3.更改工作目录

#cd Python-2.7.3

4.安装

 yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make

#./configure
#make all
#make install
#make clean
#make distclean

5.查看版本信息

#/usr/local/bin/python2.7 -V

6.建立软连接，使系统默认的 python指向 python2.7

#mv /usr/bin/python /usr/bin/python2.6.6
#ln -s /usr/local/bin/python2.7 /usr/bin/python

7.重新检验Python 版本

#python -V

8解决系统 Python 软链接指向 Python2.7 版本后，因为yum是不兼容 Python 2.7的，所以yum不能正常工作，我们需要指定 yum 的Python版本

#vi /usr/bin/yum

将文件头部的
#!/usr/bin/python

改成
#!/usr/bin/python2.6.6

http://www.zhangchun.org/the-centos6-3-upgrade-python-to-2-7-3-

这篇教程就到这里了，但是不久就突然发现输入法图标不见了，然后打字没有候选框！iBus 崩了！再次进行搜索，又是版本问题 iBus也是不支持Python2.7的啊！

于是。。。

以前在使用Python的时候，都是使用root用户安装好的全局python，现在，因为root用户安装的Python版本太低，同时自己没有root权限去对全局Python升级，所以要在非root用户下安装自己指定的Python。因此，就重新整理了一份如何在Linux环境下使用非root用户安装python及其相关的库，以备不时之需。

安装python

python版本库https://www.python.org/ftp/python/，此处我选择2.7.5版本的，在安装python的时候，使用--prefix指定安装路径即可，命令如下：

wget https://www.python.org/ftp/python/2.7.5/Python-2.7.5.tgz
tar -xzf Python-2.7.5.tgz
cd Python-2.7.5
mkdir -p /home/liudiwei/software/python27 
./configure --prefix="/home/liudiwei/software/python27"
make
make install

[liujianzuo@sy01-db3 pip-8.1.1]$ cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=/home/liujianzuo/bin/python/bin:$PATH:$HOME/bin

export PATH

[liujianzuo@sy01-db3 ~]$ . .bash_profile

[liujianzuo@sy01-db3 ~]$ which python
~/bin/python/bin/python

安装setuptools

setuptools主要是为安装pip做准备的，下面是从下载到安装的全部命令,使用上面安装的指定路径的python/home/liudiwei/software/python27/bin/python进行安装：

https://pypi.python.org/pypi/setuptools页面最下面的有它的安装链接

cd /home/work/prober/src/lib/thirdparty
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-12.0.3.tar.gz#md5=f07e4b0f4c1c9368fcd980d888b29a65 
tar xvf setuptools-12.0.3.tar.gz
cd setuptools-12.0.3
python setup.py install
cd ..
wget --no-check-certificate https://pypi.python.org/packages/41/27/9a8d24e1b55bd8c85e4d022da2922cb206f183e2d18fee4e320c9547e751/pip-8.1.1.tar.gz#md5=6b86f11841e89c8241d689956ba99ed7
tar -xzf pip-8.1.1.tar.gz
cd pip-8.1.1
python setup.py install
cd ..
# 升级pip
python -m pip install --upgrade pip

安装pip

使用pip来安装python相关库，方便简单，此处将python setup.py install的python换成自己安装的指定路径下的python/home/liudiwei/software/python27/bin/python setup.py install.

wget --no-check-certificate https://pypi.python.org/packages/41/27/9a8d24e1b55bd8c85e4d022da2922cb206f183e2d18fee4e320c9547e751/pip-8.1.1.tar.gz#md5=6b86f11841e89c8241d689956ba99ed7
tar -xzf pip-8.1.1.tar.gz
cd pip-8.1.1
python setup.py install

安装相关库

进入python安装目录的bin路径下，安装下面相关库，经测试，下列库均可安装。

• simplejson
• redis
• numpy
• scipy
• sklearn

安装命令：

cd /home/liudiwei/software/python27/bin/
./pip install simplejson
./pip install redis
./pip install numpy
./pip install scipy
./pip install sklearn

关于matplotlib的安装，因为系统有些依赖包没有安装而导致matplotlib安装失败，如libpng， freetype等，待后续安装完成后，再来完善。

 

 

9.配置iBus

分别用 vi 打开下面两个文件，找到 exec python 那一行，把exec python 改为 exec python2.6 保存，退出。iBus在重启后就恢复正常了！是不是很开心？

#vi /usr/bin/ibus-setup

#vi/usr/libexec/ibus-ui-gtk

二 、centos 安装django  python支持的mysql模块

yum -y install mysql-devel

[root@ayibang-server ~]# yum install -y MySQL-python

安装uwsgi  尽量别装 2版本 会报错。 当然用如下方法装2 版本 指定python版本安装uwsgi也行。 待测。

重装 uwsgi1.9版本 指定python版本 python2.7

[root@ayibang-server soft_ware]# tar zxf uwsgi-1.9.6.tar.gz 
[root@ayibang-server soft_ware]# cd uwsgi-1.9.6
[root@ayibang-server uwsgi-1.9.6]# python
python python-config python2 python2-config python2.7 python2.7-config
[root@ayibang-server uwsgi-1.9.6]# python2.7 uwsgiconfig.py --build

装django

[root@ayibang-server soft_ware]# tar zxvf Django-1.8.4.tar.gz 

　　　　　　　　　　　　　　　　　　cd Django-1.8.4 之后 如果执行 安装 就是python版本问题

[root@ayibang-server Django-1.8.4]# python setup.py install
Traceback (most recent call last):
File "setup.py", line 32, in <module>
version = __import__('django').get_version()
File "/data/soft_ware/Django-1.8.4/django/__init__.py", line 1, in <module>
from django.utils.version import get_version
File "/data/soft_ware/Django-1.8.4/django/utils/version.py", line 7, in <module>
from django.utils.lru_cache import lru_cache
File "/data/soft_ware/Django-1.8.4/django/utils/lru_cache.py", line 28
fasttypes = {int, str, frozenset, type(None)},
^
SyntaxError: invalid syntax

解决

[root@ayibang-server soft_ware]# wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz

接下来就是 第一步的操作； 安装2.7版本python

四 报错 没装settools

[root@ayibang-server Django-1.8.4]# python setup.py install
Traceback (most recent call last):
File "setup.py", line 5, in <module>
from setuptools import find_packages, setup
ImportError: No module named setuptools

1. 下载setuptools及pip的源码包

	setuptools与pip都是python的模块

	setuptools源码包: https://pypi.python.org/pypi/setuptools

	pip源码包: https://pypi.python.org/pypi/pip#downloads

2. 安装setuptools与pip

目前下载的版本是setuptools-12.0.5.tar.gz与pip-6.0.6.tar.gz

先安装setuptools, 进行setuptools的源码根目录下, 执行以下命令进行setuptools模块的安装:

# python setup.py install

安装完setuptools后, 接着安装pip, 进入pip的源码包根目录下, 执行以下命令进行安装:

# python setup.py build
# python setup.py install

安装完pip后. 看看pip都安装在哪里. 执行以下命令:

# whereis pip

然后再执行 # pip  命令并回车, 如果无法用pip命令, 则可通过创建pip软链接, 执行以下命令:

重装django 检测

[root@ayibang-server Django-1.8.7]# python
Python 2.7.9 (default, Dec 3 2015, 01:04:49)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>>

五 5.关联django到nginx

服务器已经在跑PHP站点，现在新生成一个虚拟服务器

[root@ayibang-server ~]# cat /etc/nginx/conf.d/django.conf
server {
listen 8000;
server_name 192.168.1.200;
location / {
include uwsgi_params;
uwsgi_pass 0.0.0.0:9000;
}
}

完成后重启下nginx服务
$ sudo /etc/init.d/nginx restart

六 配置 uwsgi 启动文件   这里有个错 ，网上文章有错误 网上的文件写的可能是早期的 版本。 

1 py文件启动
  

[root@ayibang-server ~]# cd /data/soft_ware/mysite/  #进到项目目录
[root@ayibang-server mysite]# ls
app01 db.sqlite3 demo.ini demo.py demo.pyc manage.py mysite

编辑一个py文件
[root@ayibang-server mysite]# cat demo.py
#!/usr/bin/env python
#coding:utf-8
import os
from django.core.wsgi import get_wsgi_application   #网上的大都导入的其他模块 这个版本1.9 uwsgi 1.8 django 可能就不支持了
os.environ['DJANGO_SETTINGS_MODULE']='mysite.settings' #项目名 mysite 记得改 ； setting 
application = get_wsgi_application()

启动 uwsgi  如下端口 对应 你的nginx的pass 端口   记住应用 你自己安装的 uwsg 看前面的第2三4补

[root@ayibang-server mysite]# /data/soft_ware/uwsgi-1.9.6/uwsgi -s 0.0.0.0:9000 -w demo

2  ini 文件启动

[root@ayibang-server ~]# cd /data/soft_ware/mysite/  #进到项目目录
[root@ayibang-server mysite]# ls 

[uwsgi]
socket = 0.0.0.0:9000
processes = 3  #进程数 
chdir = /data/soft_ware/mysite/ #项目名 mysite 记得改
pythonpath = /usr/local/bin/python
env = DJANGO_SETTINGS_MODULE=mysite.settings   #项目名 mysite 记得改 ； setting 
module = django.core.wsgi:get_wsgi_application()

ini 文件 启动方式

[root@ayibang-server s10day11]# /data/soft_ware/uwsgi-1.9.6/uwsgi demo.ini 

对比 我的 另一个项目 的不同

[root@ayibang-server ~]# cd /data/soft_ware/s10day11/
[root@ayibang-server s10day11]# ls
app01 app03 app04 db.sqlite3 demo.ini demo.py demo.pyc manage.py s10day11 statics templates test
[root@ayibang-server s10day11]# cat demo.py
#!/usr/bin/env python
#coding:utf-8
import os
from django.core.wsgi import get_wsgi_application
os.environ['DJANGO_SETTINGS_MODULE']='s10day11.settings'
application = get_wsgi_application()
[root@ayibang-server s10day11]# cat demo.ini
[uwsgi]
socket = 0.0.0.0:9000
processes = 9
chdir = /data/soft_ware/s10day11/
pythonpath = /usr/local/bin/python
env = DJANGO_SETTINGS_MODULE=s10day11.settings
module = django.core.wsgi:get_wsgi_application()

 127.0.0.1:9090
2
 /var/www/erp/erp

开始 解决报错1  python 版本不一致

先pip uninstall uwsgi,然后yum install -y pcre pcre-devel pcre-static

安装pip

[root@ayibang-server soft_ware]# tar zxf pip-6.0.6.tar.gz
[root@ayibang-server soft_ware]# cd pip-
-bash: cd: pip-: No such file or directory
[root@ayibang-server soft_ware]# cd pip-6.0.6
[root@ayibang-server pip-6.0.6]# python setup.py build

[root@ayibang-server pip-6.0.6]# python setup.py install

创建项目 app

[root@ayibang-server soft_ware]# python /usr/local/bin/django-admin.py startproject mysite
[root@ayibang-server soft_ware]# python manage.py startapp app01

原来是 uwsgi是识别的 python2.6 而2.6 对django1.8不支持太好

[root@ayibang-server uwsgi-2.0.6]# ls /usr/bin/python*
/usr/bin/python /usr/bin/python2 /usr/bin/python2.6-config

/usr/local/bin/python-config /usr/local/bin/python2-config /usr/local/bin/python2.7-config

重装 uwsgi1.9版本 指定python版本 python2.7

[root@ayibang-server soft_ware]# tar zxf uwsgi-1.9.6.tar.gz
[root@ayibang-server soft_ware]# cd uwsgi-1.9.6

参照网上用uwsgi+nginx配置python环境时，报了这么个错，google发现是WSGI application的问题，好象是因为django升级，配置有所变化。

原来：

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

改成：

from django.core.wsgi import get_wsgi_application

application = get_wsgi_application()

重启一下uwsgi。

网上找来的解决办法，希望有帮助。

后补：也可能是python版本和django版本不兼容问题，重新安装django并选定安装的版本就可以了

原来的 是如下 方式写的 不过我的改成上面 黄色部分  如下是老版本的 调用方法

配置并运行一个简单的python页面

$ cd /var/www/mysite
/var/www/mysite$ sudo vi demo.py
输入如下代码：
import  os
import  django.core.handlers.wsgi
os.environ['DJANGO_SETTINGS_MODULE']='mysite.settings'
application=django.core.handlers.wsgi.WSGIHandler()

/var/www/mysite$ uwsgi -s 127.0.0.1:9090 -w demo 

如安装了libxml2，也可用如下方法处理：
在app目录创建个django.xml文件
/var/www/mysite$ sudo vi django.xml
内容如下：

 127.0.0.1:9090
2
 /var/www/erp/erp
 ..
 DJANGO_SETTINGS_MODULE=mysite.settings
 django.core.handlers.wsgi:WSGIHandler()


启动方式：
/var/www/mysite$ uwsgi -x django.xml 

另一种配置方式，用于没有安装libxml2：
ini配置文件
/var/www/mysite$ sudo vi django.ini
[uwsgi]
socket = 127.0.0.1:9090
processes = 2
chdir = /var/www/mysite/mysite/
pythonpath = ..
env = DJANGO_SETTINGS_MODULE=mysite.settings
module = django.core.handlers.wsgi:WSGIHandler()

启动方式：
/var/www/mysite$ uwsgi django.ini 

服务成功启动后访问 http://127.0.0.1:8000，如能看到欢迎信息，就说明运行环境配置好了。更多的设置可以看下The_Django_Book
