django+nginx+uwsgi部署web站点
环境：
django：1.8.16
python：2.7.13
pip：2.7
uwsgi：2.0.15
project路径： /opt/cmdb/
Uwsgi的安装配置
1、安装python2.7 （省略安装过程）
2、安装pip2.7 （省略安装过程）
3、安装uwsgi（注意：要用pip2.7安装）
pip2.7 install uwsgipip2.7 install requestsln -s /usr/local/python2.7/bin/uwsgi /usr/bin/uwsgi
4、配置uwsgi.ini
路径： /opt/cmdb/uwsgi.ini
文件内容：
[root@localhost cmdb]# cat uwsgi.ini
[uwsgi]socket = 127.0.0.1:8088chdir=/opt/cmdbwsgi-file = cmdb/wsgi.pypidfile = /var/run/uwsgi.piddaemonize = /var/log/uwsgi.logperl-auto-reload = 2#buffer-size = 102400master = trueprocesses = 2threads = 4
Uwsgi：常用参数和选项
关于参数的具体使用，可以阅读官方文档http://uwsgi-docs.readthedocs.org/en/latest/Options.html ，在这里列出一些常用的参数：
chdir 项目目录
home virtualenv目录（如没有运行virtualenv虚拟环境，则无需设置）
socket 套接字文件或TCP套接字，例如：site1.uwsgi.sock 或 127.0.0.1:8000
uid 用户id
gid 用户组id
processes 工作进程数
harakiri 进程超过该时间未响应就重启该进程（默认单位为秒）
module 要启动的wsgi模块入口，如：mysite.wsgi:application
ini 指定ini配置文件
xml 指定xml配置文件（与ini类似）
file 指定要运行的wsgi程序文件，如：test.py
emperor Emperor模式
so-keepalive 开启TCP KEEPALIVE（unix套接字方式下无效）
uwsgi服务init脚本 /etc/init.d/cmdb

1、安装nginx
yum -y install nginx
2、配置nginx
[root@localhost cmdb]# cat /etc/nginx/conf.d/cmdb.conf
upstream django { server 127.0.0.1:8088; }server { listen 80; server_name 172.16.42.128; charset utf-8; client_max_body_size 10M; location /static { alias /opt/cmdb/static; } location / { uwsgi_send_timeout 300; uwsgi_connect_timeout 300; uwsgi_read_timeout 300; uwsgi_pass django; include /etc/nginx/uwsgi_params; }}启动站点
1、启动nginx服务
/etc/init.d/nginx start (删除默认的default.conf配置)
2、启动uwsgi
/etc/init.d/cmdb start
排错：
1、在实际操作中发现，启动uwsgi服务后，访问站点出现"502 Bad Gateway"的报错，后来发现是在settings中设置了不允许访问站点
ALLOWED_HOSTS = []
改成
ALLOWED_HOSTS = ['*']
后问题解决。
2、由于python2.6 不支持django1.8 ，所以需要在服务器上安装python2.7，并且在安装之前，最好输入以下命令，将可能用到的包都装上，否则出现问题时，需要重新编译安装python2.7
yum -y install zlib-devel bzip2-devel openssl-devel yum -y install ncurses-devel sqlite-devel readline-devel yum -y install tk-devel gdbm-devel db4-devel libpcap-develyum -y install xz-devel libffi-devel
3、用pip安装uwsgi时，一定要用pip2.7(用python2.7安装的pip) 进行安装
4、invalid request block size: 4161 (max 4096)...skip报错解决
在访问站点时，出现了invalid request block size: 4161 (max 4096)...skip报错解决的报错。
解决办法是在uwsgi.ini配置文件中增加一条配置：buffer-size = 102400
将buffer-size设置大一些
