2019-01-11 nginx+uwsgi+python+django spirit 论坛项目

1. 通过uwsgi启动， 测试uwsgi+django是否正常:

打开浏览器，输入127.0.0.1:

因为网站是部署在docker 镜像上的， 所以从宿主机访问加上了80的对应映射端口8090，同时，可以看到，这种方式静态文件都无法找到(不知是否是我的方法漏了步骤？)

 

 

 2.  nginx + uwsgi + django 启动：

      /etc/nginx/sites-enabled/default

      

root@3a560ed12c50:/code/mysite/mysite# cat /etc/nginx/sites-enabled/default
##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# https://www.nginx.com/resources/wiki/start/
# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
# https://wiki.debian.org/Nginx/DirectoryStructure
#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.
#
# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
##

# Default server configuration
#
server {
listen 80 default_server;
listen [::]:80 default_server;

# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.

#
# Read up on ssl_ciphers to ensure a secure configuration.

#
# include snippets/snakeoil.conf;

root /var/www/html;

# Add index.php to the list if you are using PHP

server_name _;

# location / {
# First attempt to serve request as file, then

# }

# location /uwsgi {
# include /etc/nginx/uwsgi_params;

# }

location / {
root /code/mysite;
uwsgi_pass 127.0.0.1:8001;
include /etc/nginx/uwsgi_params;
}

location /static {

alias /code/mysite/static/;
}

# pass PHP scripts to FastCGI server
#
#location ~ \.php$ {

#
# # With php-fpm (or other unix sockets):
# fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
#}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}

# Virtual Host configuration for example.com
#
# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
# listen 80;
# listen [::]:80;
#
# server_name example.com;
#
# root /var/www/example.com;
# index index.html;
#
# location / {
# try_files $uri $uri/ =404;
# }
#}

 a. 启动 nginx:  

     service nginx start  或者 service nginx reload + service nginx restart

b. 启动uwsgi:

    uwsgi --socket :8001 --module mysite.wsgi

 

然后通过浏览器访问 

 

这个时候是正常的，静态文件是可以访问的，样式都是对的。

 

 

改进：

1. 每次通过传递参数启动uwsgi比较麻烦，所以更好的方式是用配置文件的方式，配置文件可以用ini和xml两种格式

    a.  uwsgi.ini

root@3a560ed12c50:/code/mysite# cat uwsgi.ini
[uwsgi]
socket = :8001

# the base directory (project full path)
chdir = /code/mysite

# pidfile for record run pid

# run process background and save log to daemonize
daemonize = UWSGI.log
root@3a560ed12c50:/code/mysite#

    b.  uwsgi.xml

root@3a560ed12c50:/code/mysite# cat uwsgi.xml
<uwsgi>
<socket>127.0.0.1:8001</socket>

<processes>4</processes>
<daemonize>uwsgi_xml.log</daemonize>
</uwsgi>
root@3a560ed12c50:/code/mysite#

 

启动:     uwsgi --ini uwsgi.ini  

# 因为配置了后台运行，所以用ps查看uwsgi进程，可以看到有5个uwsgi进程，一个是master，4个worker

uwsgi -x uwsgi.xml

注意，这里只有4个uwsgi进程，因为没有指定master为true, 如果需要，可以添加:

<master>true</master>
