• Centos7(博主使用的是ubuntu)
• 数据库: mysql
• 编程语言: python3.6
• 队列缓存: redis
• web反向代理: nginx
• 依赖环境: flask pymysqlclient wtform sqlachemy redis

mark

cd /usr/bin

mark

可以看到腾讯云已经默认安装有python3.5的环境

centos安装lnmp环境

mark

ssh root@ip# 查看服务器配置(centos)
cat /etc/redhat-release# 查看内存剩余
free -m# 查看硬盘剩余
df -h

安装python3.6的依赖包

yum -y install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel
sqllite-devel

下载python3.6.1的包

然后解包

tar -zxf python-3.6.1.tgz
cd python-3.6.1
./configure -- prefix=/usr/localyum -y install gcc gcc-c++make altinstall

更改python链接

cd /usr/binmv python python.backup# 创建软连接
ln -s /usr/local/bin/python3.6 /usr/bin/python
ln -s /usr/local/bin/python3.6 /usr/bin/python3cd /usr/bin/
ls yum*
vim yum

修改第一行尾python2

vim yum-config-manager

修改第一行尾python2

vim yum-debug-restore
vim yum-group-manager
vim yum-build-dep
vim yum-debug-dump
vim yumdownloader
vim /usr/libexec/urlgrabber-ext-down

修改第一行尾python2

此时输入python就是3.6的python了。

博主的腾讯云此时输入python3.5是python环境

安装mysql

centos

yum -y install mariadb-server# 启动
systemctl start mariadb.service# 设置开机自启
enable mariadb.service

mysqladmin -uroot password "root"
mysql -uroot -proot

修改mysql的字符集

vim /etc/my.cnf

mysqld节点添加

character--set-server=utf8

然后restart

systemctl restart mariadb.service

安装nginx

centos下:

拷贝我们的nginx安装包到服务器

scp nginx.tar.gz root@192.0.x.x:/root/

安装依赖包

yum -y install gcc gcc-c++ openssl-devel pcre-devel httpd-tools

tar -zxf nginx.tar.gz
cd nginx/useradd nginx
./configure -- prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_mp4_module --with-http_flv_moudlemake && make installln -s /usr/local/nginx/sbin/nginx /usr/sbin/

启动nginx

nginx
netstat -anptu | grep nginx

部署微电影网站

1. 安装依赖包
2. 关闭调试模式 app.debug = False
3. 修改mysql数据库连接，导入数据
4. 开启多个端口后台运行
5. 配置nginx 反向代理

首先manage.py中从flask_script 中

pip install flask-script
from flask_script import Managermanage = Manager(app)if __name__ == "__main__":manage.run()

命令行工具。

修改服务器数据库连接。

使用xshell的xz命令上传req.txt

mkvirtualenv --python=python3 movie
pip install -r req.txt

把项目zip打包上传到服务器

unzip movie_project

导入数据

create database movie;
use movie;
source /root/movie.sql;

上传nginx的配置文件

worker_processes 4;
events {worker_connections 262140;
}
http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;limit_conn_zone $binary_remote_addr zone=addr:5m;upstream movie {server 127.0.0.1:5001;server 127.0.0.1:5002;server 127.0.0.1:5003;server 127.0.0.1:5004;}server {listen 80;server_name movie.mtianyan.cn;location / {root html;index index.html index.htm;proxy_pass http://movie;}location ~ \.flv$ {flv;limit_conn addr 4;limit_rate 1024k;rewrite ^/static/uploads/(.+?).flv$ /movie_project/app/static/uploads/$1.flv permanent;}location ~ \.mp4$ {mp4;limit_conn addr 4;limit_rate 1024k;rewrite ^/static/uploads/(.+?).mp4$ /movie_project/app/static/uploads/$1.mp4 permanent;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}}
}

将项目拷贝到nginx的html目录

cp -r movie_project /usr/local/nginx/html
或
cp -r movie_project /usr/share/nginx/html

找到nginx的目录

cp nginx.conf /usr/local/nginx/conf/ubuntu: cp nginx.conf /etc/nginx/conf.d

nginx -s stop

cd /usr/local/nginx/html/movie_projectpython manage.py runserver

报错

nohup: ignoring input and appending output to '/home/ubuntu/nohup.out'

代码有错误，路径没加全。

然后开上四个进程。换端口就行

nohup python manage.py runserver -h 139.199.189.211 -p 5001

流媒体访问限制

1. 限制单个ip能发起的连接: limit_conn addr 1;
2. 限制视频速率: limit_rate 1024k;
3. 刷新nginx nginx -s reload
