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

./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\root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

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
