Ubuntu16.04下Django项目的部署

起飞前的准备

# 首先在Ubuntu的当前用户zhang下新建data文件夹，然后在data文件夹下新建你的项目目录
root@zhang-virtual-machine:/home/zhang/data# mkdir my_web_project

root@zhang-virtual-machine:/home/zhang/data# ls

my_web_project

root@zhang-virtual-machine:/home/zhang/data# cd my_web_project/

# virtualenv --no-site-paceages env   创建虚拟环境，--no-site-packages 表示一个干净的目录，不会安装没必要的包

root@zhang-virtual-machine:/home/zhang/data/my_web_project# virtualenv --no-site-packages env

Using base prefix '/usr'

New python executable in /home/zhang/data/my_web_project/env/bin/python3

Also creating executable in /home/zhang/data/my_web_project/env/bin/python

Installing setuptools, pip, wheel...done.

root@zhang-virtual-machine:/home/zhang/data/my_web_project# ls

env

root@zhang-virtual-machine:/home/zhang/data/my_web_project# cd env/

root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# ls

bin  include  lib  pip-selfcheck.json

# 激活虚拟环境

root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# source bin/activate

#查看版本，查看到当前的环境下没有太多的包

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip -V

pip 10.0.0 from /home/zhang/data/my_web_project/env/lib/python3.5/site-packages/pip (python 3.5)

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip list

Package    Version

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

pip        10.0.0

setuptools 39.0.1

wheel      0.31.0 

# 退出虚拟环境

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# deactivate

root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# source bin/activate

# 安装1.10.4版本的Django
(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip install django==1.10.4

Collecting django==1.10.4

# 安装uwsgi
(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip install uwsgi

Collecting uwsgi

第一步：uwsgi

首先测试uwsgi，并用uwsgi启动服务

def application(env, start_response):

    start_response('200 OK', [('Content-Type','text/html')])

    return [b"Hello uwsgi!"]

刚开始按照网上说的用这个方法启动老是报错

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# python app.py

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# uwsgi --http :8008 --wsfi-file app.py

uwsgi: unrecognized option '--wsfi-file'

getopt_long() error

最后发现启动的方式默认是socket的方式

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# uwsgi --http-socket :8008 --wsgi-file app.py

*** Starting uWSGI 2.0.17 (64bit) on [Tue Apr 17 19:05:22 2018] ***

compiled with version: 5.4.0 20160609 on 18 April 2018 01:30:18

os: Linux-4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017

    pkill -f -9 uwsgi  #停止uwsgi

第二步：nginx

# 直接在命令行下运行 apt-get install nginx

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# apt-get install nginx

nginx的启动与关闭

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# service nginx stop

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# ps aux | grep nginx

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# service nginx start

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# ps aux | grep nginx

root      55075  0.0  0.0 124968  1420 ?        Ss   19:24   0:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;

www-data  55076  0.0  0.1 125332  3072 ?        S    19:24   0:00 nginx: worker process

www-data  55077  0.0  0.1 125332  3072 ?        S    19:24   0:00 nginx: worker process

www-data  55078  0.0  0.1 125332  3072 ?        S    19:24   0:00 nginx: worker process

www-data  55079  0.0  0.1 125332  3072 ?        S    19:24   0:00 nginx: worker process

root      55082  0.0  0.0  14220   988 pts/20   S+   19:24   0:00 grep --color=auto nginx

(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project#

nginx的配置文件都在

# /etc/nginx/...

(env) root@zhang-virtual-machine:/etc/nginx# ls

conf.d        fastcgi_params  koi-win     nginx.conf    scgi_params      sites-enabled  uwsgi_params

fastcgi.conf  koi-utf         mime.types  proxy_params  sites-available  snippets       win-utf

此时访问浏览器可以看到如下：

第三步：Django+uwsgi+nginx

nginx的配置文件所在路径：

/etc/nginx/nginx.conf
uwsgi 所在路径：项目更目录

启动项目：

uwsgi --ini demo.ini &    #利用配置文件启动，默认不在终端显示

/etc/init.d/nginx start     #启动nginx

附加：

supervisor是一个对进程管理的软件，可以帮助我们启动uwsgi并维护（uwsgi进程关闭时，自动将其启动起来）。

安装：apt-get install supervisor

配置 vim /etc/supervisor/supervisor.conf

[supervisord]

http_port=/var/tmp/supervisor.sock ; (default is to run a UNIX domain socket server)

;http_port=127.0.0.1:9001  ; (alternately, ip_address:port specifies AF_INET)

;sockchmod=0700              ; AF_UNIX socketmode (AF_INET ignore, default 0700)

;sockchown=nobody.nogroup     ; AF_UNIX socket uid.gid owner (AF_INET ignores)

;umask=022                   ; (process file creation umask;default 022)

logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)

logfile_maxbytes=50MB       ; (max main logfile bytes b4 rotation;default 50MB)

logfile_backups=10          ; (num of main logfile rotation backups;default 10)

loglevel=info               ; (logging level;default info; others: debug,warn)

pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)

nodaemon=false              ; (start in foreground if true;default false)

minfds=1024                 ; (min. avail startup file descriptors;default 1024)

minprocs=200                ; (min. avail process descriptors;default 200)

;nocleanup=true              ; (don't clean up tempfiles at start;default false)

;http_username=user          ; (default is no username (open system))

;http_password=123           ; (default is no password (open system))

;childlogdir=/tmp            ; ('AUTO' child log dir, default $TEMP)

;user=chrism                 ; (default is current user, required if root)

;directory=/tmp              ; (default is not to cd during start)

;environment=KEY=value       ; (key value pairs to add to environment)

[supervisorctl]

serverurl=unix:///var/tmp/supervisor.sock ; use a unix:// URL  for a unix socket

;serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket

;username=chris              ; should be same as http_username if set

;password=123                ; should be same as http_password if set

;prompt=mysupervisor         ; cmd line prompt (default "supervisor")

; The below sample program section shows all possible program subsection values,

; create one or more 'real' program: sections to be able to control them under

; supervisor.

;[program:theprogramname]

;command=/bin/cat            ; the program (relative uses PATH, can take args)

;priority=999                ; the relative start priority (default 999)

;autostart=true              ; start at supervisord start (default: true)

;autorestart=true            ; retstart at unexpected quit (default: true)

;startsecs=10                ; number of secs prog must stay running (def. 10)

;startretries=3              ; max # of serial start failures (default 3)

;exitcodes=0,2               ; 'expected' exit codes for process (default 0,2)

;stopsignal=QUIT             ; signal used to kill process (default TERM)

;stopwaitsecs=10             ; max num secs to wait before SIGKILL (default 10)

;user=chrism                 ; setuid to this UNIX account to run the program

;log_stdout=true             ; if true, log program stdout (default true)

;log_stderr=true             ; if true, log program stderr (def false)

;logfile=/var/log/cat.log    ; child log path, use NONE for none; default AUTO

;logfile_maxbytes=1MB        ; max # logfile bytes b4 rotation (default 50MB)

;logfile_backups=10          ; # of logfile backups (default 10)

[program:oldboy]

command=/usr/local/bin/uwsgi /data/oldboy/oldboy.ini ;命令

priority=999                ; 优先级（越小越优先）

autostart=true              ; supervisord启动时，该程序也启动

autorestart=true            ; 异常退出时，自动启动

startsecs=10                ; 启动后持续10s后未发生异常，才表示启动成功

startretries=3              ; 异常后，自动重启次数

exitcodes=0,2               ; exit异常抛出的是0、2时才认为是异常

stopsignal=QUIT             ; 杀进程的信号

stopwaitsecs=10             ; 向进程发出stopsignal后等待OS向supervisord返回SIGCHILD 的时间。若超时则supervisord将使用SIGKILL杀进程

user=chrism                 ; 设置启动该程序的用户

log_stdout=true             ; 如果为True，则记录程序日志

log_stderr=false            ; 如果为True，则记录程序错误日志

logfile=/var/log/cat.log    ; 程序日志路径

logfile_maxbytes=1MB        ; 日志文件最大大小

logfile_backups=10          ; 日志文件最大数量

配置文件

启动：

supervisord /etc/supervisor.conf       #这个总是报错，不知道什么原因

或

/etc/init.d/supervisor start              #这个比较好用

# 通过配置文件启动

        uwsgi --ini uwsgi.ini           # 这样启动之后后台可以看到，不方便
　　　　 uwsgi --ini uwsgi.ini &          # 建议这种，启动之后后台运行

# 会生成两个文件

            PID文件 他是标识这个程序所处的状态

            SOCK文件  他是用来和其他程序通信的

    # 停止uwsgi

        uwsgi --stop uwsgi.pid

    # 重载配置

        uwsgi --reload uwsgi.ini
