Ubuntu+nginx+ftmp+obs搭建直播流服务器学习

第一步安装依赖

安装gcc g++的依赖库

sudo apt-get install build-essential
sudo apt-get install libtool

安装pcre依赖库

sudo apt-get update
sudo apt-get install libpcre3 libpcre3-dev

安装zlib依赖库

sudo apt-get install zlib1g-dev

安装SSL依赖库

1、wget https://www.openssl.org/source/openssl-3.0.1.tar.gz
2、tar -zxvf openssl-3.0.1.tar.gz
3、cd openssl-3.0.1
4、使用./config生成MakeFile，不加任何参数，默认的安装位置为：/usr/local/bin/openssl
5、sudo make && make install
>到上一步openssl就算安装好了，但是还无法使用，需要通过软链接的方式将新旧版本就行替换，依次运行下列命令。
sudo mv /usr/bin/openssl /usr/bin/openssl.old //将旧版本的openssl进行备份
sudo ln -s /usr/local/bin/openssl /usr/bin/openssl //将新版本的openssl进行软链接
cd /etc/ //进入etc目录
su //下一步一定要切换到root用户
echo “/usr/local/lib” >> ld.so.conf //将openssl的安装路径加入配置中
ldconfig //重新加载配置

安装nginx

切换成root用户步骤
1、sudo passwd root
2、修改root密码

>**#下载最新版本**
两种方式 （本文使用wget安装）
1：git clone https://github.com/nginx/nginx.git
2: wget http://nginx.org/download/nginx-1.20.2.tar.gz**#解压：**tar -zxvf nginx-1.20.2.tar.gz**#进入到解压目录**cd  nginx-1.20.2**#下载最新版本**./configure --prefix=/usr/local/nginx --with-openssl=/usr/local/openssl-3.0.1**#编译**make**#安装**sudo make install**#启动：**
sudo /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
**#至此nginx就安装成功了**

安装nginx-http-flv-module

网上很多都是装nginx-rtmp-module 但是nginx-http-flv-module 包含了 nginx-rtmp-module 所有的功能，所以不要将 nginx-http-flv-module 和 nginx-rtmp-module 一起编译。所以本文装的是nginx-http-flv-module ，因为后面要利用flv 拉流

配置参考地址
https://github.com/winshining/nginx-http-flv-module/blob/master/README.md

安装nginx-http-flv-module步骤

1.下载nginx-http-flv-module
git clone https://github.com/winshining/nginx-http-flv-module.git
2…/configure --add-module=…/nginx-http-flv-module --prefix=/usr/local/nginx --with-openssl=/usr/local/openssl-3.0.1
3.sudo make && make install

配置nginx

下载OBS

https://obsproject.com/wiki/install-instructions#linux
这里有相关命令

>设置obs 推流
>修改/usr/local/nginx/html/index.html下的页面
只需要将ip端口号改成对应的就行

</body></html>

一个小坑
>记得关闭防火墙
或者用以下命令开启对应端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=1935/tcp --permanent

访问对应ip 192.168.140.172即可显示拉流画面

一些安装过程中的小tips

修改ubuntu的镜像源地址加速下载本文修改为清华大学镜像源

地址：https://mirrors.tuna.tsinghua.edu.cn/help/AOSP/
1、备份Ubuntu默认的源地址
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
2、vim /etc/apt/sources.list
