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

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.拉取所有需要的静态文件到同一个目录

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/
