FastRunner(后端)生产模式uWSGI+Nginx+Su

1.安装uWSGI

pip install uWSGI

2.uWSGI配置uwsgi.ini

[uwsgi]

# 设置变量
project = FasterRunner
base = /home/faster

# 通过引用变量的方式设置Django项目根路径
chdir = %(base)/%(project)
# Django项目的wsgi配置
module = %(project).wsgi:application

master = true
processes = 4

# socket 通信文件
socket = %(base)/%(project)/%(project).sock
chmod-socket = 666
vacuum = true

3.配置Django的settings文件wsgi.py

Django设置多配置文件(生产和开发)

import os

from django.core.wsgi import get_wsgi_application

# 指定Django使用生产配置FasterRunner.settings.pro
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'FasterRunner.settings.pro')

application = get_wsgi_application()

3.1测试uWSGI

# 进入Django项目的根路径
cd /home/faster/FasterRunner
# 运行uwsgi 
uwsgi --ini ./uwsgi.ini

4.Nginx配置uwsgi.conf,最好通过include的方式导入配置

server {
   # 监听8000端口
    listen       8000;
    server_name  10.0.3.57;

    location / {
        include         uwsgi_params;
        # 需要和uwsgi.ini 中的 socket 通信文件一样
        uwsgi_pass     unix:/home/faster/FasterRunner/FasterRunner.sock;
    }
}

4.1Nginx测试

# 测试Nginx配置文件
nginx -t

# 重新加载,使Nginx配置文件生效  
nginx -s reload

# 查看当前端口监听,确认8000端口被Nginx监听
(fasterenv) [root@faster_3_57 FasterRunner]# netstat -tunlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name     
tcp        0      0 0.0.0.0:8000            0.0.0.0:*               LISTEN      27106/nginx: master

5.Supervisor管理uWSGI

supervisor守护进程虚拟环境部署Django

创建uWSGI启动的配置文件uwsgi.conf
command 中需要指定uwsgi的绝对路径.此处是虚拟环境中的uwsgi路径
Supervisor配置的注释是;

[program:uwsgi]
command= /home/faster/.virtualenvs/fasterenv/bin/uwsgi --ini ./uwsgi.ini
directory=/home/faster/FasterRunner
stopasgroup=true
stopsignal=QUIT
user=faster
autostart=true
autorestart=true
stderr_logfile=/home/faster/err.log
stdout_logfile=/home/faster/out.log

5.1通过Supervisor启动uWSGI

# 重启整个 supervisor的服务
 supervisorctl reload

# 指定启动uwsgi,此处是program后跟随的名字
supervisorctl start uwsgi

# 停止uwsgi
supervisorctl stop uwsgi

6.uWSGI日志抛出异常Permission denied

tailf  /var/log/nginx/error.log

2019/06/15 15:41:01 [crit] 29077#0: *65 connect() to unix:/home/faster/FasterRunner/FasterRunner.sock failed (13: Permission denied) while connecting to upstream, 
client: 192.168.24.131, server: 10.0.3.57, request: "OPTIONS /api/user/login/ HTTP/1.1",
upstream: "uwsgi://unix:/home/faster/FasterRunner/FasterRunner.sock:", host: "10.0.3.57:8000", referrer: "http://10.0.3.57:8080/fastrunner/login"

6.1修改Nginx启动用户

# 找到Nginx当前主配置
[root@faster_3_57 FasterRunner]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful


# 编辑Nginx主配置
vim /etc/nginx/nginx.conf

#user nginx;
user faster;

# 测试Nginx配置文件
nginx -t

# 重新加载,使Nginx配置文件生效  
nginx -s reload
