实验环境
一台最小化的 CentOS 7.3 虚拟机
ip: 192.168.204.133

一、安装基本环境

1. 安装基本环境

   yum install -y epel*
   yum install -y nginx python-pip python-devel \
   pcre-devel libxml2-devel gcc vim tree psmisc

   pip安装uwsgi时需要gcc
   uwsgi进程管理时需要psmisc

2. 安装python库文件

   pip install web.py
   pip install uwsgi

3. 创建网站根目录

   mkdir /var/wwwroot
   cd /var/wwwroot

4. 编写测试网页
   创建并编辑/var/wwwroot/main.py

   #!/usr/bin/python
   #coding=utf-8
   import web    
   urls = (
   '/(.*)', 'hello'
   )
   app = web.application(urls, globals())
   class hello:        
   def GET(self, name):
       if not name:
           name = 'World'
       return 'Hello, ' + name + '!'
   if __name__ == "__main__":
   app.run()
   # 使用nginx作web服务时，注意添加下面这句话
   application = app.wsgifunc()

   

5. 对main.py添加可执行权限

   chmod +x /var/wwwroot/main.py

6. 关闭防火墙

   setenforce 0
   systemctl stop firewalld
   systemctl disable firewalld

二、配置nginx和uwsgi

1. 修改nginx的配置文件
   修改server下的root为网站根目录
   修改location中的配置如下

   location / {
       include uwsgi_params;
       uwsgi_pass 127.0.0.1:9090; #此套接字为uwsgi监听的地址和端口
       uwsgi_param UWSGI_CHDIR $document_root; #此处代表网站根目录
       uwsgi_param UWSGI_SCRIPT main; #此处为应用的入口文件
   }

   

2. 启动nginx

   systemctl start nginx
   netstat -anpt | grep nginx

3. 配置uwsgi
   创建并编辑/ect/uwsgi.ini

   [uwsgi]
   socket = 127.0.0.1:9090
   workers = 4

   

4. 启动uwsgi
   开启一个 新终端! 新终端!! 新终端!!! 执行以下命令

   uwsgi --ini /etc/uwsgi.ini 2>&1 &
   exit

   

5. 回到之前的终端，查看uwsgi是否正常启动

   netstat -antp | grep -E "9090|uwsgi"

   

6. 停止uwsgi

   killall uwsgi
   netstat -antp | grep -E "9090|uwsgi"

   

三、测试

1. 在宿主机访问
   

四、一键部署脚本

#!/bin/bash
# 关闭防火墙
setenforce 0
systemctl stop firewalld
systemctl disable firewalld
# 安装基础软件包
yum install -y epel*
yum install -y nginx python-pip python-devel \
pcre-devel libxml2-devel gcc vim tree psmisc
# 安装python模块
pip install web.py
pip install uwsgi
# 建立网站根目录
mkdir /var/wwwroot
cd /var/wwwroot
# 建立测试网页
echo -e "#!/usr/bin/python
#coding=utf-8
import web    
urls = (
    '/(.*)', 'hello'
)
app = web.application(urls, globals())
class hello:        
    def GET(self, name):
        if not name:
            name = 'World'
        return 'Hello, ' + name + '!'
if __name__ == \"__main__\":
    app.run()
# 使用nginx作web服务时，注意添加下面这句话
application = app.wsgifunc()
" > /var/wwwroot/main.py
# 添加可执行权限
chmod +x /var/wwwroot/main.py
# 修改nginx配置文件
NGINX_CONF_PATH=/etc/nginx/nginx.conf
sed -i 's/^[^#].*root.*/        root         \/var\/wwwroot;/g' ${NGINX_CONF_PATH}
sed -i "47 a \            include uwsgi_params;" ${NGINX_CONF_PATH}
sed -i "48 a \            uwsgi_pass 127.0.0.1:9090;" ${NGINX_CONF_PATH}
sed -i "49 a \            uwsgi_param UWSGI_CHDIR \$document_root;" ${NGINX_CONF_PATH}
sed -i "50 a \            uwsgi_param UWSGI_SCRIPT main;
" ${NGINX_CONF_PATH}
# 启动nginx
systemctl start nginx
netstat -anpt | grep nginx
# 配置uwsgi
echo -e "[uwsgi]
socket = 127.0.0.1:9090
workers = 4
" > /etc/uwsgi.ini
# 启动uwsgi
echo -e "uwsgi starting..."
uwsgi --ini /etc/uwsgi.ini 2>&1 &
