centos7 下通过nginx+uwsgi部署django应用

centos7 下通过nginx+uwsgi部署django应用

1. 安装python3.6

1. 获取

wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz

tar -xzvf Python-3.6.2.tgz -C  /tmp

cd  /tmp/Python-3.6.2/

2. 把Python3.6安装到 /usr/local 目录

./configure --prefix=/usr/local

make

make altinstall

3. 更改/usr/bin/python链接

ln -s /usr/local/bin/python3.6 /usr/bin/python3

2. maridb

1. 安装

    sudo yum install mariadb-server

2. 启动, 重启

    sudo systemctl start mariadb

    sudo systemctl restart mariadb

3. 设置bind-ip

    vim /etc/my.cnf

    在 [mysqld]:

        下面加一行

        bind-address = 0.0.0.0

4. 设置外部ip可以访问

    先进入mysql才能运行下面命令:

        mysql 直接进入就行

    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

    FLUSH PRIVILEGES

5. 设置阿里云的对外端口

  视频中有讲解这部分

6. 安装mysqlclient出问题

    centos 7:

        yum install python-devel mariadb-devel -y

    ubuntu:

        sudo apt-get install libmysqlclient-dev

    然后:

        pip install mysqlclient

3. 安装nginx

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-centos-7

4. 安装virtualenvwrapper

yum install python-setuptools python-devel

pip install virtualenvwrapper

编辑.bashrc文件

export WORKON_HOME=$HOME/.virtualenvs

source /usr/local/bin/virtualenvwrapper.sh

重新加载.bashrc文件

source  ~/.bashrc

新建虚拟环境

mkvirtualenv mxonline

进入虚拟环境

workon mxonline

安装pip包

我们可以通过 pip freeze > requirements.txt 将本地的虚拟环境安装包相信信息导出来

然后将requirements.txt文件上传到服务器之后运行:

pip install -r requirements.txt

安装依赖包

5. 安装uwsgi

pip install uwsgi

6. 测试uwsgi

uwsgi --http :8000 --module MxOnline.wsgi

7. 配置nginx

新建uc_nginx.conf

# the upstream component nginx needs to connect to

upstream django {

# server unix:///path/to/your/mysite/mysite.sock; # for a file socket

server 127.0.0.1:8000; # for a web port socket (we'll use this first)

}

# configuration of the server

server {

# the port your site will be served on

listen      80;

# the domain name it will serve for

server_name 你的ip地址 ; # substitute your machine's IP address or FQDN

charset    utf-8;

# max upload size

client_max_body_size 75M;  # adjust to taste

# Django media

location /media  {

    alias 你的目录/Mxonline/media;  # 指向django的media目录

}

location /static {

    alias 你的目录/Mxonline/static; # 指向django的static目录

}

# Finally, send all non-media requests to the Django server.

location / {

    uwsgi_pass  django;

    include    uwsgi_params; # the uwsgi_params file you installed

}

}

8. 将该配置文件加入到nginx的启动配置文件中

sudo ln -s 你的目录/Mxonline/conf/nginx/uc_nginx.conf /etc/nginx/conf.d/

8. 拉取所有需要的static file 到同一个目录

在django的setting文件中,添加下面一行内容:

    STATIC_ROOT = os.path.join(BASE_DIR, "static/")

运行命令

    python manage.py collectstatic

9. 运行nginx

sudo /usr/sbin/nginx

这里需要注意 一定是直接用nginx命令启动, 不要用systemctl启动nginx不然会有权限问题

10. 通过配置文件启动uwsgi

新建uwsgi.ini 配置文件, 内容如下:

    # mysite_uwsgi.ini file

    [uwsgi]

    # Django-related settings

    # the base directory (full path)

    chdir          = /home/bobby/Projects/MxOnline

    # Django's wsgi file

    module          = MxOnline.wsgi

    # the virtualenv (full path)

    # process-related settings

    # master

    master          = true

    # maximum number of worker processes

    processes      = 10

    # the socket (use the full path to be safe

    socket          = 127.0.0.1:8000

    # ... with appropriate permissions - may be needed

    # chmod-socket    = 664

    # clear environment on exit

    vacuum          = true

    virtualenv = /home/bobby/.virtualenvs/mxonline

    logto = /tmp/mylog.log

注:

    chdir: 表示需要操作的目录,也就是项目的目录

    module: wsgi文件的路径

    processes: 进程数

    virtualenv:虚拟环境的目录

workon mxonline

uwsgi -i 你的目录/Mxonline/conf/uwsgi.ini &

访问

http://你的ip地址/
