# Centos 7 下部署Django + uWSGI + Nginx
## 环境:
Python: 3.6
Django: 2.1
OS: CentOS 7 x86_64
uwsgi: 2.0.17
## 安装Python3.6
* 不要删除自带的python2.7,否则会出问题,因为centos许多软件需要依赖系统自带python
* 安装依赖工具 yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel mysql-devel gcc gcc-devel python-devel
* 下载 wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
* 解压 tar -zxvf Python-3.6.5.tgz
* 移动至规范的放软件的目录下 mv Python-3.6.5 /usr/local
* 安装:
* cd /usr/local/Python-3.6.5/
* ./configure
* make
* make install
* 验证
* python -V
* source /home/cosmic/py3.6env/bin/activate 进入虚拟环境
## 安装uWSGI
* 安装 pip install uwsgi
* 验证
```
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return [b"Hello Django"]
```
```
uwsgi --http :8001 --wsgi-file test.py
```
浏览器访问,网页能显示 Hello Django 那么就没问题
* 如果安装失败
* deactivate 退出虚拟环境
* yum install -y python-devel
* easy_install uwsgi
## 安装Nginx
* 配置源
vi /etc/yum.repos.d/nginx.repo 添加下面内容
```
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/7/x86_64/
gpgcheck=0
enabled=1
```
gpkcheck=0 表示对从这个源下载的rpm包不进行校验;
enable=1 表示启用这个源。
* yum install nginx
* 启动nginx:
systemctl start nginx
* 修改默认端口号(默认为80)
```
vim /etc/nginx/conf.d/default.conf
server {
listen 8089;
listen [::]:8089;
...
...
}
```
* systemctl restart nginx 重启nginx,直接访问http://ip:8089 能看到nginx的欢迎界面即可。
## 配置
配置uwsgi启动django的参数
```
vim django_uwsgi.ini
[uwsgi]
# 通过uwsgi访问django需要配置成http
# 通过nginx请求uwsgi来访问django 需要配置成socket
# 9000 是django的端口号
socket = :9000
# web项目根目录
chdir = /home/root/pydj/django_one
# module指定项目自带的的wsgi配置文件位置
module = django_one.wsgi
# 允许存在主进程
master = true
# 开启进程数量
processes = 3
# 服务器退出时自动清理环境
vacuum = true
```
## 配置nginx
```
vi /etc/nginx/conf.d/default.conf
# 在文件最后,新加一个server
server {
listen 8089;
listen [::]:8089;
server_name 127.0.0.1 192.168.10.114;
location / {
include /etc/nginx/uwsgi_params;
uwsgi_pass 127.0.0.1:9000;
}
location /index/ {
root /index/;
}
location /static{
alias /home/root/pydj/django_one/sign/static;
}
}
```
* 8089 是对外的端口号
* server_name nginx代理uwsgi对外的ip
* 127.0.0.1:9000 即当nginx收到8089端口的请求时,直接将请求转发给 127.0.0.1:9000
## uwsgi启动django
```
# 进入项目根目录
/home/root/pydj/django_one
# 启动
uwsgi --ini django_uwsgi.ini
```
## 重启Nginx
systemctl restart nginx
