centos7下通过uwsgi+nginx+django将项目部署到服务器

centos7 下通过uwsgi，nginx部署django应用

1.安装python3.7

2.安装依赖包

	yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel 			
	gcc gcc-c++  openssl-devel libffi-devel python-devel mariadb-devel

3.下载python源码

wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz
tar -xzvf Python-3.7.3.tgz -C  /tmp
cd  /tmp/Python-3.7.3/

4.把Python3.7安装到 /usr/local 目录

./configure --prefix=/usr/local
make
make altinstall   #这一步比较耗时

5.更改/usr/bin/python链接

ln -s /usr/local/bin/python3.7 /usr/bin/python3
ln -s /usr/local/bin/pip3.7 /usr/bin/pip3

maridb 和 redis

1.安装

sudo yum install mariadb-server

2.启动， 重启

sudo systemctl start mariadb
sudo systemctl restart mariadb

设置安全规则 配置mysql的端口

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

FLUSH PRIVILEGES;

5.设置阿里云的对外端口

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

7.安装redis

yum install redis
service redis start

安装nginx

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

1. sudo yum install epel-release
2. sudo yum install nginx
3. sudo systemctl start nginx
4. 安装virtualenvwrapper

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
yum install python-setuptools python-devel
pip install virtualenvwrapper

编辑.bashrc文件
export WORKON_HOME=$HOME/.virtualenvs
source /usr/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
然后将requirements.txt文件上传到服务器之后运行：

安装依赖包
pip install -r requirements.txt

安装uwsgi

pip install uwsgi

测试uwsgi

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

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
}
}

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/

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

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

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/
