centos 7下 django 1.11 + nginx 1.12 + uwsgi 2.0

之前写过一个博客关于如何安装django的，见下网址，

http://www.cnblogs.com/qinhan/p/8732626.html

还有一个网址如何安装nginx的

http://www.cnblogs.com/qinhan/p/8780098.html

这次说说django搭配nginx+uwsgi部署生产环境

部署之前测试环境把防火墙都关掉,用以下两条命令

iptables -X

iptables -F

 

首先安装uwsgi, 可以登陆官网下载

http://uwsgi-docs.readthedocs.io/en/latest/Download.html

随后查看安装手册

http://uwsgi-docs.readthedocs.io/en/latest/Install.html

 

yum groupinstall "Development Tools"
yum install python
yum install python-devel
python uwsgiconfig.py --build

python3 setup.py install   #官方文档里面没写这步，但是需要执行

官方文档用的是标红的安装过程，执行红色的python uwsgiconfig.py --build 需要继续执行python3 setup.py install才能用的时候环境变量找到uwsgi


以下截取部分安装过程

(monitor2) insp_ap@inspect01:~/project/hanqin/django/monitor2/tmp/uwsgi-2.0.17> python3 setup.py install

(monitor2) insp_ap@inspect01:~/project/hanqin/django/monitor2> uwsgi --version
2.0.17

如果没有报错，表明安装完成，安装完成后可以用对应命令uwsgi --version查看安装版本

 

 

接下来启动uwsgi, 我这里只说用配置文件进行启动

insp_ap@inspect01:~/project/hanqin/django/monitor2/config> view uwsgi.ini 
[uwsgi]
# 项目目录
chdir=/home/insp_ap/project/hanqin/django/monitor2/jiankong2
# 指定项目的application
module=jiankong2.wsgi:application
# 指定sock的文件路径
socket=/home/insp_ap/project/hanqin/django/monitor2/tmp/uwsgi.sock
#socket=127.0.0.1:8001
# 进程个数
workers=1
pidfile=/home/insp_ap/project/hanqin/django/monitor2/tmp/uwsgi.pid
# 指定IP端口
http=10.129.6.78:9001
# 指定静态文件
static-map=/static=/home/insp_ap/project/hanqin/django/monitor2/jiankong2/statics
# 启动uwsgi的用户名和用户组
uid=insp_ap
gid=insp_ap
# 启用主进程
master=true
# 自动移除unix Socket和pid文件当服务停止的时候
vacuum=true
# 序列化接受的内容，如果可能的话
thunder-lock=true
# 启用线程
enable-threads=true
# 设置自中断时间
harakiri=30
# 设置缓冲
post-buffering=4096
# 设置日志目录
daemonize=/home/insp_ap/project/hanqin/django/monitor2/tmp/uwsgi.log



执行启动命令
(monitor2) insp_ap@inspect01:~/project/hanqin/django/monitor2/config> uwsgi --ini uwsgi.ini 

可以看到进程启动，并且访问网站成功

(monitor2) insp_ap@inspect01:~/project/hanqin/django/monitor2/config> ps -fu $USER | grep uwsgi
insp_ap 9576 1 28 12:00 ? 00:00:00   uwsgi --ini uwsgi.ini
insp_ap 9942 9576 0 12:00 ? 00:00:00 uwsgi --ini uwsgi.ini
insp_ap 9943 9576 0 12:00 ? 00:00:00 uwsgi --ini uwsgi.ini

 

 

 

 

 

接下来我们要加入Nginx, 做成最终的nginx+django+uwsgi模式

首先修改uwsgi.ini文件，可以看到和前面相比修改了部分内容,其中端口8001要注意，待会会和nginx里面的conf文件里面的一个配置相同
(monitor2) insp_ap@inspect01:~/project/hanqin/django/monitor2/config> view uwsgi.ini

# uwsig使用配置文件启动
[uwsgi]
# 项目目录
chdir=/home/insp_ap/project/hanqin/django/monitor2/jiankong2
# 指定项目的application
module=jiankong2.wsgi:application
# 指定sock的文件路径
#socket=/home/insp_ap/project/hanqin/django/monitor2/tmp/uwsgi.sock
socket=10.129.6.78:8001
# 进程个数
workers=1
pidfile=/home/insp_ap/project/hanqin/django/monitor2/tmp/uwsgi.pid
# 指定IP端口
#http=144.131.252.51:9001
# 指定静态文件
#static-map=/static=/home/yy1s/myproject/mon2/jiankong2/statics
# 启动uwsgi的用户名和用户组
uid=1000
gid=100
# 启用主进程
master=true
# 自动移除unix Socket和pid文件当服务停止的时候
vacuum=true
# 序列化接受的内容，如果可能的话
thunder-lock=true
# 启用线程
enable-threads=true
# 设置自中断时间
harakiri=30
# 设置缓冲
post-buffering=4096
# 设置日志目录
daemonize=/home/insp_ap/project/hanqin/django/monitor2/tmp/uwsgi.log


修改nginx配置

inspect01:/usr/local/nginx1_12_2/conf # pwd
/usr/local/nginx1_12_2/conf
inspect01:/usr/local/nginx1_12_2/conf # view nginx.conf

 

#这里只显示修改的部分内容，其中location /static是指向django项目里面的静态内容包括css font js等，并且8001端口需要和前面的uwsgi.ini配置的8001端口相同

server {
listen 8080;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;
location /static {
#expires 30d;
#autoindex on;
#add_header Cache-Control private;
alias /home/insp_ap/project/hanqin/django/monitor2/jiankong2/statics;
}

location / {
include uwsgi_params;
uwsgi_pass 10.129.6.78:8001;
uwsgi_read_timeout 20;
#root html;
#index index.html index.htm;
}

 

配置完成以后启动nginx以及uwsgi

inspect01:/usr/local/nginx1_12_2/sbin # ./nginx 

(monitor2) insp_ap@inspect01:~/project/hanqin/django/monitor2/config> uwsgi --ini uwsgi.ini

 

启动以后可以看到8080以及8001都处于监听状态

inspect01:/usr/local/nginx1_12_2/sbin # netstat -an | grep 8080
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN

inspect01:/usr/local/nginx1_12_2/sbin # netstat -an | grep 8001
tcp 0 0 10.129.6.78:8001 0.0.0.0:* LISTEN

 

 

访问网页，可以看到10.129.6.78:8080 端口可以访问

这里说明下8080端口是前端页面也就是浏览器访问Nginx的端口，8001端口为uwsgi和nginx之间通讯的端口，

如果暂时搞不明白就先按照我上面的配置配起来以后在研究。
