- 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
cd /usr/bin
mark
可以看到腾讯云已经默认安装有python3.5的环境
使用Nginx作为Python Web的反向代理实战
动手实战实现Redis数据库主从同步
nginx结合jwplayer实现视频流媒体点播
centos安装lnmp环境
markssh 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/local
yum -y install gcc gcc-c++
make altinstall
更改python链接
cd /usr/bin
mv 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/python3
cd /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_moudle
make && make install
ln -s /usr/local/nginx/sbin/nginx /usr/sbin/
启动nginx
nginx
netstat -anptu | grep nginx
部署微电影网站
- 安装依赖包
- 关闭调试模式 app.debug = False
- 修改mysql数据库连接,导入数据
- 开启多个端口后台运行
- 配置nginx 反向代理
首先manage.py中从flask_script 中
pip install flask-script
from flask_script import Manager
manage = 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_project
python 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
- 限制单个ip能发起的连接: limit_conn addr 1;
- 限制视频速率: limit_rate 1024k;
- 刷新nginx nginx -s reload
