一、安装webRTC环境的准备工作

1.centos 下载位置：

https://mirrors.openanolis.cn/anolis/8.4/isos/GA/x86_64/

2.win 10 没有 hyper 

解决办法：【转】windows 没有hyper-v 解决方法

3.安装 centos

4.centos 启动失败

解决办法：

 5.centos 无法连接网络（ping 114.114.114.114 失败）

解决方法：

ip addr 查看网卡名称；

vi /etc/sysconfig/network-scripts/ifcfg-网卡名字：vi /etc/sysconfig/network-scripts/ifcfg-eth0

在文件中修改：ONBOOT=ON 修改为ONBOOT=yes

在该文件中添加 DNS1 = 8.8.8.8  DNS2=4.2.2.2

重启网卡 ifup eth0

二、centos 工具安装

yum -y install wget

yum install -y git

yum install -y python3-pip

yum install -y meson

 yum install -y re2c
yum install cmake 
yum install libevent-devel
yum install curl-devel
sudo yum install gcc-c++
 
git 全局配置：
git config –global http.sslVerify “false”
 
 

三、janus webRTC 环境安装

1.安装依赖

openssl-devel libsrtp-devel sofia-sip-devel glib2-devel /
opus-devel libogg-devel libcurl-devel pkgconfig /
libconfig-devel libtool autoconf automake

2.libnice

git clone https://gitlab.freedesktop.org/libnice/libnice

cd libnice

meson –prefix=/usr build && ninja -C build && sudo ninja -C build install

3.usrsctp

git clone https://github.com/sctplab/usrsctp

cd usrsctp

./bootstrap

./configure –prefix=/usr –disable-programs –disable-inet –disable-inet6 –disable-dependency-track

make && sudo make install

4.libsrtp

wget https://github.com/cisco/libsrtp/archive/v2.2.0.tar.gz

tar xfv v2.2.0.tar.gz

cd libsrtp-2.2.0

make configs

7.启动： 

/opt/janus/bin/janus

四、可能遇到的问题：

问题：/usr/bin/env: ‘python’: No such file or directory
解决方法：sudo ln -s /usr/bin/python3 /usr/bin/python
