略有補(bǔ)充(可能出現(xiàn)錯(cuò)誤及解決辦法)
環(huán)境：
CentOS X64 6.4
nginx 1.5.6
Python 2.7.5
正文：
一：安裝需要的類(lèi)庫(kù)及Python2.7.5
安裝必要的開(kāi)發(fā)包
yum?groupinstall?"Development?tools"
yum?install?zlib-devel?bzip2-devel?pcre-devel?openssl-devel?ncurses-devel?sqlite-devel?readline-devel?tk-devel
CentOS 自帶Python2.6.6，但我們可以再安裝Python2.7.5：
cd?~
wget?http://python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2
tar?xvf?Python-2.7.5.tar.bz2
cd?Python-2.7.5
./configure?--prefix=/usr/local
make?&&?make?altinstall
安裝完畢后，可是使用”python2.7”命令進(jìn)入python2.7的環(huán)境。
二：安裝Python包管理
easy_install包https://pypi.python.org/pypi/distribute
方便安裝Python的開(kāi)發(fā)包
cd?~
wget?https://pypi.python.org/packages/source/d/distribute/distribute-0.6.49.tar.gz
tar?xf?distribute-0.6.49.tar.gz
cd?distribute-0.6.49python2.7?setup.py?install
easy_install?--version
紅色部分必須是“python2.7”，否則將安裝到默認(rèn)的2.6環(huán)境內(nèi)。
pip包https://pypi.python.org/pypi/pip
安裝pip的好處是可以pip list、pip uninstall 管理Python包， easy_install沒(méi)有這個(gè)功能，只有uninstall
easy_install?pip
pip?--version
三：安裝uwsgi
uwsgi:https://pypi.python.org/pypi/uWSGI
uwsgi參數(shù)詳解：http://uwsgi-docs.readthedocs.org/en/latest/Options.html
pip?install?uwsgi
uwsgi?--version
測(cè)試uwsgi是否正常：
新建test.py文件，內(nèi)容如下：
def?application(env,?start_response):
start_response('200?OK',?[('Content-Type','text/html')])
return?"Hello?World"
然后在終端運(yùn)行：
uwsgi?--http?:8001?--wsgi-file?test.py
在瀏覽器內(nèi)輸入：http://你購(gòu)買(mǎi)的云主機(jī)公網(wǎng)ip:8001，看是否有“Hello World”輸出，若沒(méi)有輸出，請(qǐng)檢查你的安裝過(guò)程。
四：安裝django
pip?install?django
測(cè)試django是否正常，運(yùn)行：
django-admin.py?startproject?demosite
cd?demositepython2.7?manage.py?runserver?0.0.0.0:8002
在瀏覽器內(nèi)輸入：http://1你購(gòu)買(mǎi)的云主機(jī)公網(wǎng):8002，檢查django是否運(yùn)行正常。
五：安裝nginx
cd?~
wget?http://nginx.org/download/nginx-1.5.6.tar.gz
tar?xf?nginx-1.5.6.tar.gz
cd?nginx-1.5.6
./configure?--prefix=/usr/local/nginx-1.5.6?\
--with-http_stub_status_module?\
--with-http_gzip_static_module
make?&&?make?install
安裝Nginx時(shí)報(bào)錯(cuò)
錯(cuò)誤提示：
./configure:?error:?the?HTTP?rewrite?module?requires?the?PCRE?library.
安裝pcre-devel與openssl-devel解決問(wèn)題
yum?-y?install?pcre-devel?openssl?openssl-devel
./configure?--prefix=/usr/local/nginx
make
make?install
六：配置uwsgi
uwsgi支持ini、xml等多種配置方式，但個(gè)人感覺(jué)ini更方便：
在/ect/目錄下新建uwsgi9090.ini，添加如下配置：
[uwsgi]
socket?=
master?=?true?????????//主進(jìn)程
vhost?=?true??????????//多站模式
no-stie?=?true????????//多站模式時(shí)不設(shè)置入口模塊和文件
workers?=?2???????????//子進(jìn)程數(shù)
reload-mercy?=?10
vacuum?=?true?????????//退出、重啟時(shí)清理文件
max-requests?=?1000
limit-as?=?512
buffer-sizi?=?30000
pidfile?=?/var/run/uwsgi9090.pid????//pid文件，用于下面的腳本啟動(dòng)、停止該進(jìn)程
daemonize?=?/website/uwsgi9090.log
設(shè)置uwsgi開(kāi)機(jī)啟動(dòng)，在/etc/init.d/目錄下新建uwsgi9090文件，內(nèi)容如下：
uwsgi9090
#!?/bin/sh
#?chkconfig:?2345?55?25
#?Description:?Startup?script?for?uwsgi?webserver?on?Debian.?Place?in?/etc/init.d?and

echo?-en?"Reloading?$NAME:?\n"
do_reload
;;
*)
echo?"Usage:?$SCRIPTNAME?{start|stop|reload}"?>&2
exit?3
;;
esac
exit?0
uwsgi9090
然后在終端執(zhí)行：
--?添加服務(wù)
chkconfig?--add?uwsgi9090
--?設(shè)置開(kāi)機(jī)啟動(dòng)
chkconfig?uwsgi9090?on
七：設(shè)置nginx
找到nginx的安裝目錄/usr/local/nginx，打開(kāi)conf/nginx.conf文件，修改server配置
server?{
listen???????80;
server_name??localhost;
location?/?{
include??uwsgi_params;
uwsgi_pass??;??????????????//必須和uwsgi中的設(shè)置一致
index??index.html?index.htm;
client_max_body_size?35m;
}
}
注意 ：安裝django這步中startproject的demosite路徑，需要和nginx.conf中 uwsgi_param UWSGI_CHDIR /demosite;對(duì)應(yīng)上。
設(shè)置nginx開(kāi)機(jī)啟動(dòng)，在/etc/init.d/目錄下新建nginx文件，內(nèi)容如下：
nginx
#!/bin/sh
#
#?nginx?-?this?script?starts?and?stops?the?nginx?daemon
#
#?chkconfig:???-?85?15
#?description:??Nginx?is?an?HTTP(S)?server,?HTTP(S)?reverse?\

[?"$NETWORKING"?=?"no"?]?&&?exit?0
nginx="/opt/nginx-1.5.6/sbin/nginx"
prog=$(basename?$nginx)

echo?$"Usage:?$0?{start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit?2
esac
nginx
然后在終端執(zhí)行：
--?添加服務(wù)
chkconfig?--add?nginx
--?設(shè)置開(kāi)機(jī)啟動(dòng)
chkconfig?nginx?on
八：測(cè)試
OK，一切配置完畢，在終端運(yùn)行
service?uwsgi9090?start
service?nginx?start
錯(cuò)誤1:
[root@VM_23_251_centos nginx-1.5.6]# service uwsgi9090 start
env: /etc/init.d/uwsgi9090: Permission denied
[root@VM_23_251_centos nginx-1.5.6]# service nginx start
env: /etc/init.d/nginx: Permission denied
解決辦法1：把可執(zhí)行勾選上
錯(cuò)誤2：
[root@VM_23_251_centos ~]# sudo service nginx start
env: /etc/init.d/nginx: No such file or directory
解決辦法1：
Be careful what text editors you use on your local Windows computer. Some create Windows-style line endings (\r\n, CR-LF), which cause problems like this on Unix-like systems such as Linux or Mac OS X.
If you use such an editor, adjust its settings so that it creates files with Unix-style line endings. If the editor has no such setting, you should not be using it at all.
文本格式由windows 改為unix版
錯(cuò)誤3：
*** WARNING: Can't find section "uwsgi" in INI configuration file /etc/uwsgi9090.ini ***
解決辦法3：
在瀏覽器輸入：http://云主機(jī)公網(wǎng)ip，恭喜你可以看到django的“It work”了~
九：多站配置
我采用運(yùn)行多個(gè)uwsgi服務(wù)的方法來(lái)實(shí)現(xiàn)多個(gè)站點(diǎn)。
重復(fù)第六步，創(chuàng)建uwsgi9091.ini，并相應(yīng)修改文件中的
socket?=?127.0.0.1:9091
pidfile?=?/var/run/uwsgi9091.pid
daemonize?=?/website/uwsgi9091.log
并創(chuàng)建服務(wù)uwsgi9091，設(shè)置開(kāi)機(jī)啟動(dòng)。
然后修改nginx的配置文件為：
nginx
然后我們就可以通過(guò)http://127.0.0.1:1300來(lái)訪問(wèn)新的網(wǎng)站了。
十：其他配置
防火墻設(shè)置
CentOS默認(rèn)關(guān)閉外部對(duì)80、3306等端口的訪問(wèn)，所以要在其他計(jì)算機(jī)訪問(wèn)這臺(tái)服務(wù)器，就必須修改防火墻配置，打開(kāi)/etc/sysconfig/iptables
在“-A INPUT –m state --state NEW –m tcp –p –dport 22 –j ACCEPT”，下添加：
-A?INPUT?-m?state?--state?NEW?-m?tcp?-p?-dport?80?-j?ACCEPT
-A?INPUT?-m?state?--state?NEW?-m?tcp?-p?-dport?3306?-j?ACCEPT
然后保存，并關(guān)閉該文件，在終端內(nèi)運(yùn)行下面的命令，刷新防火墻配置：
service?iptables?restart
安裝Mysqldb
yum?-y?install?mysql-develeasy_install-2.7?MySQL-python
注意紅色部分，easy_install-2.7,否則它將默認(rèn)安裝到Python2.6環(huán)境內(nèi)。
------------------------------------------------------------------------------------------------------------------
2014年12月02日添加：
CentOS 7中默認(rèn)使用Firewalld做防火墻，所以修改iptables后，在重啟系統(tǒng)后，根本不管用。
Firewalld中添加端口方法如下：
firewall-cmd --zone=public --add-port=3306/tcp--permanent
firewall-cmd --reload
