配置前台项目

上线前配置

settings.js

base_url: 'http://39.100.107.176:8000',  // 设置公网ip

上线

1）本地项目打包，前往luffycity项目目录下
>: cnpm run build

2）上传
>: scp -r dist root@39.100.107.176:~

3）移动并重命名
mv ~/dist /home/html

4）去向Nginx配置目录，备份配置，完全更新配置：填入下方内容
>: cd /usr/local/nginx/conf
>: cp nginx.conf nginx.conf.bak
>: vim nginx.conf
>: ggdG
>: i

events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    server {
        listen 80;
        server_name  127.0.0.1; # 改为自己的域名，没域名修改为127.0.0.1:80
        charset utf-8;
        location / {
            root /home/html; # html访问路径
            index index.html; # html文件名称
            try_files $uri $uri/ /index.html; # 解决单页面应用刷新404问题
        }
    }
}                                                                   

配置后台项目

上线前配置

prod.py：上线的配置文件，内容拷贝dev.py，前身就是settings.py

1）需要做上线修改的内容
DEBUG = False
ALLOWED_HOSTS = [
    '39.100.107.176'  # 公网ip地址
]

CORS_ORIGIN_ALLOW_ALL = True  # 允许所有跨域
CORS_ORIGIN_WHITELIST = [
]

wsgi.py 和 manage.py

1）需要做上线修改的内容
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'luffyapi.settings.prod')

上线

1）在项目的虚拟环境安装uwsgi
>: mkvirtualenv luffy
>: workon luffy
# 走下方 pip导入导出依赖 说明，将本地的环境依赖同步到服务器环境中
>: pip install uwsgi

2）项目根目录配置uwsgi：填入下方内容
>: mkdir /home/project

# 注：将后台项目移至到/home/project，可以上传，也可以git，项目设置公开（私密需要配置ssl）
>: cd /home/project && git clone https://gitee.com/doctor_owen/luffyapi.git 
>: vim /home/project/luffyapi/luffyapi.xml

<uwsgi>    
   <socket>127.0.0.1:8808</socket> <!-- 内部端口，自定义 --> 
   <chdir>/home/project/luffyapi/</chdir> <!-- 项目路径 -->            
   <module>luffyapi.wsgi</module>  <!-- luffyapi为wsgi.py所在目录名--> 
   <processes>4</processes> <!-- 进程数 -->     
   <daemonize>uwsgi.log</daemonize> <!-- 日志文件 -->
</uwsgi>

####  3）配置上线项目的settings：见后台项目部署准备视频

4）去向Nginx配置目录，备份配置，完全更新配置：填入下方内容
>: vim /usr/local/nginx/conf/nginx.conf

5）在原来基础上添加一个server
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    server {
        listen 8000;
        server_name  127.0.0.1; # 改为自己的域名，没域名修改为127.0.0.1:80
        charset utf-8;
        location / {
           include uwsgi_params;
           uwsgi_pass 127.0.0.1:8808;  # 端口要和uwsgi里配置的一样
           uwsgi_param UWSGI_SCRIPT luffyapi.wsgi;  #wsgi.py所在的目录名+.wsgi
           uwsgi_param UWSGI_CHDIR /home/project/luffyapi/; # 项目路径
        }
    }
}

见下方配置：pip环境 + 数据库设置 + django2.0源码

5）启动uwsgi
>: uwsgi -x /home/project/luffyapi/luffyapi.xml

6）启动nginx
>: nginx -s stop
>: nginx
>: nginx -s reload

7）浏览器测试：http://39.100.107.176:8000/xadmin

8）关闭uwsgi所有进程
>: pkill -f uwsgi -9

pip导入导出依赖

1) 本地导出项目环境，上传线上，导入到线上环境中

本地操作
# 桌面新建env文件夹，开启终端进入文件夹，执行下方命名
>: cd Desktopenv
>: pip3 freeze > packages.txt
# 注：把xadmin删掉
>: scp -r packages.txt root@39.100.107.176:~

服务器操作
# 进入虚拟环境
>: workon luffy
# 导入
>: pip3 install -r packages.txt
# 安装xadmin
>: pip install https://codeload.github.com/sshwsfc/xadmin/zip/django2

数据库设置 + django2.0源码

1.管理员连接数据库
>: mysql -uroot -pOwen1234?

2.创建数据库
>: create database luffy default charset=utf8;

# 3.设置权限账号密码
# 拥有公网或局域网，其他主机连mysql
>: grant all privileges on luffy.* to 'luffy'@'%' identified by 'Luffy123?';
# 要是本机连mysql连不上，再增加localhost域，本机就可以登录了
>: grant all privileges on luffy.* to 'luffy'@'localhost' identified by 'Luffy123?';
# 设置完有权限限制的账号后一定要刷新权限
>: flush privileges;

4.退出mysql
quit

5.修改 prod.py | manage.py
>: vim /home/project/luffyapi/luffyapi/settings/prod.py

"PASSWORD": "Luffy123?"

>: vim /home/project/luffyapi/manage.py

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'luffyapi.settings.prod')

6.源码修改
>: vim /root/.virtualenvs/luffy/lib/python3.6/site-packages/django/db/backends/mysql/base.py

# 36，37行注释

>: vim /root/.virtualenvs/luffy/lib/python3.6/site-packages/django/db/backends/mysql/operations.py

# 146行添加
	query = query.encode()

7.数据库迁移
>: cd /home/project/luffyapi/
>: python manage.py makemigrations
>: python manage.py migrate

8.创建超级用户
>: python manage.py createsuperuser
# 账号密码：admin|admin

后台样式问题

设置文件中配置STATIC_ROOT

# >: vim /home/project/luffyapi/luffyapi/settings/prod.py
# 在STATIC_URL下方再添加两句
STATIC_URL = '/static/'
STATIC_ROOT = '/home/project/luffyapi/luffyapi/static'  # 服务器的绝对路径
STATICFILES_DIRS = (os.path.join(BASE_DIR, "static"),)
# >: esc
# >: :wq

迁移静态样式：项目目录下

可能错误
>: mkdir /home/project/luffyapi/luffyapi/static
>: python /home/project/luffyapi/manage.py collectstatic

Nginx配置静态路径

>: vim /usr/local/nginx/conf/nginx.conf

events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    server {
        listen 8000;
        server_name  127.0.0.1; # 改为自己的域名，没域名修改为127.0.0.1:80
        charset utf-8;
        location / {
           include uwsgi_params;
           uwsgi_pass 127.0.0.1:8808;  # 端口要和uwsgi里配置的一样
           uwsgi_param UWSGI_SCRIPT luffyapi.wsgi;  #wsgi.py所在的目录名+.wsgi
           uwsgi_param UWSGI_CHDIR /home/project/luffyapi/; # 项目路径
        }
        # 新增的配置静态文件
        location /static {
            alias /home/project/luffyapi/luffyapi/static;
        }
    }
    server {
        listen 80;
        server_name  127.0.0.1; # 改为自己的域名，没域名修改为127.0.0.1:80
        charset utf-8;
        location / {
            root /home/html; # html访问路径
            index index.html; # html文件名称
            try_files $uri $uri/ /index.html; # 解决单页面应用刷新404问题
        }
    }
}

>: esc
>: :wq

重启服务

>: pkill -f uwsgi -9
>: uwsgi -x /home/project/luffyapi/luffyapi.xml
>: nginx -s reload

重点 重点 重点

# 1、真实环境和虚拟环境都要安装uwsgi，将真实环境下的uwsgi建立软连接

# 2、redis服务一定要后台启动：redis-server &

# 3、uwsgi启动django项目一定要进入虚拟环境下，因为环境都是安装在虚拟环境中

# 4、服务器的日志都会被记录在于uwsgi配置文件 luffyapi.xml 同类目下的 uwsgi.log 中

添加测试数据
