    5.虚拟环境默认根目录:~/.virtualenvs

    六:安装Nginx

    0.什么是Nginx

    Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器
    Apache和Nginx最核心的区别在于 apache 是同步多进程模型,一个连接对应一个进程;
    而 nginx 是异步的,多个连接(万级别)可以对应一个进程
    
    作用:
        http请求转发
        反向代理服务器
        负载均衡
        动静分离
    

    1.下载(耗时70s)

    wget http://nginx.org/download/nginx-1.13.7.tar.gz
    

    2.解压(耗时1s)

    tar -xf nginx-1.13.7.tar.gz
    

    3.进入目标文件

    cd nginx-1.13.7
    

    4.配置安装路径:/usr/local/nginx(耗时2s)

    ./configure --prefix=/usr/local/nginx
    

    image-20200731084647026

    5.编译并安装(耗时30s)

    make && sudo make install
    

    6.建立软链接

    ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
    

    7.测试Nginx环境,服务器运行nginx,本地访问服务器ip

    nginx
    >: 服务器绑定的域名 或 ip:80
    

    8.Nginx命令

    # 启动
    	nginx
    
    # 关闭nginx
    	nginx -s stop
    
    # 重启nginx
    	nginx -s reload
    
    # 查看端口,强行关闭
        ps -aux|grep nginx
        kill <pid:进程编号>
    

    七:前端Vue项目上线

    1.进入luffycity目录,将项目打包

    cnpm run build
    

    2.生成一个dist文件夹,用finalshell上传到服务器的 oot目录下

    image-20200731085453166

    3.移动并重命名为html

    mv ~/dist /home/html
    

    4.去向Nginx配置目录

    cd /usr/local/nginx/conf
    

    5.备份配置

    mv nginx.conf nginx.conf.bak
    

    6.创建新的配置文件,完全更新配置:填入下方内容

    vim nginx.conf
    
    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
            }
        }
    }
    

    八:后端luffyapi项目上线

    1.将luffyapi下的settings下的dev.py复制命名为pro.py修改如下

    DEBUG = False
    
    
    # 运行的host,服务端的地址,买的服务器的公网ip,或者直接填写*
    ALLOWED_HOSTS = ['*']
    
    
    # 配置数据库
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'NAME': 'luffy',
            'USER': 'luffy',
            'PASSWORD': 'Luffy1234?',
            'HOST': '127.0.0.1',
            'PORT': 3306
        },
    }
    
    
    # 后台基URL
    BASE_URL = 'http://47.98.233.34:8000'
    # 前台基URL
    LUFFY_URL = 'http://47.98.233.34'
    

    2.将manage.py复制命名为manage_pro.py修改如下

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

    3.将apps下所有app的migrations下的除了__init__.py的其他文件都删除

    4.导出项目依赖

    # 1.进入项目根目录,导出
    pip3 freeze > requirements.txt
    
    # 2.把xadmin=右边替换
    xadmin=https://codeload.github.com/sshwsfc/xadmin/zip/django2
    

    5.创建存放后台项目的目录

    mkdir /home/project
    

    6.进入后台项目管理目录

    cd /home/project
    

    7.传输后端项目

    将项目提交到git仓库,然后去服务器上拉下来,或者直接finalshell上传

    image-20200731091501465

    六:配置虚拟环境

    0.切换到后端项目下

    cd /home/project/luffyapi
    

    1.先在非虚拟环境下安装uwsgi(耗时5s)

    # 在真实环境下安装
    pip3 install uwsgi
    
    # 建立软连接
    ln -s /usr/local/python3/bin/uwsgi /usr/bin/uwsgi
    

    2.创建线上luffy项目虚拟环境(耗时5s)

    mkvirtualenv luffy
    

    3.切换到新建的虚拟环境

    workon luffy
    

    4.安装uwsgi(耗时15s)

    # 先升级一下pip和setuptools
    pip3 install --upgrade pip
    pip3 install --upgrade setuptools
    
    # 再安装uwsgi
    pip3 install uwsgi
    

    5.安装依赖(耗时40s)

    pip3 install -r requirements.txt
    

    七:完成uwsgi与nginx后台项目配置

    1.进行uwsgi服务配置,内容如下

    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>
    

    2.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
    
    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
            }
        }
        # 新增的server
        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
            }
        }
    } 
    

    八:完成项目的数据库迁移

    1.切换到后端项目

    cd /home/project/luffyapi/

    九:静态文件配置

    1.编辑后端配置文件

    vim /home/project/luffyapi/luffyapi/settings/pro.py
    

    2.修改static配置,新增STATIC_ROOT、STATICFILES_DIRS

    STATIC_URL = '/static/'
    STATIC_ROOT = '/home/project/luffyapi/luffyapi/static/'  
    STATICFILES_DIRS = (os.path.join(BASE_DIR, "static"),)
    

    3.迁移静态样式(耗时1s)

    mkdir /home/project/luffyapi/luffyapi/static
    
    python3 /home/project/luffyapi/manage_pro.py collectstatic
    

    4.Nginx配置静态路径

    # 修改nginx配置
     vim /usr/local/nginx/conf/nginx.conf
    
    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
            }
        }
        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;
            }
        }
    }
    

    十:开放端口

    1.去服务器的 “网络与安全” - “安全组”添加如下端口

    image-20200731102335250

    十一:启动服务

    1.关闭 uwsgi

    pkill -f uwsgi -9
    

    2.启动uwsgi

    uwsgi -x /home/project/luffyapi/luffyapi.xml
    

    3.关闭 nginx

    nginx -s stop
    

    4.启动 nginx

    nginx
