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

如果报错zipimport.ZipImportError: can't decompress data; zlib not available的解决办法：先安装zlib
rpm -qa | grep zlib
yum -y install zlib*

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
ECS/更多/网络和安全组/安全组配置/配置规则/快速创建规则

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/

BUG:

运行python manage.py runserver 8000报错Error: That port is already in use.端口号已经被占用

#查看与8000端口相关的服务
ps aux | grep -i manage

#清除与8000端口相关的服务
kill -9 25300
kill -9 25298
