SRS环境搭建
srs官⽹:https://github.com/ossrs/srs
码云的源速度快:https://gitee.com/winlinvip/srs.oschina.git
github的源速度慢:https://github.com/ossrs/srs.git
选择当前最新的release版本3.0
第⼀步,获取SRS。详细参考GIT获取代码
git clone https://gitee.com/winlinvip/srs.oschina.git srs.3.0-20200720
cd srs.3.0-20200720
#使⽤当前最新的3.0版本
git checkout 3.0release
cd trunk
第⼆步,编译SRS。详细参考Build
./configure && make
第三步,编写SRS配置⽂件。
详细参考
RTMP分发
Delivery HLS
Delivery HTTP FLV
编辑 conf/srs.conf ,服务器启动时指定该配置⽂件(srs的conf⽂件夹有该⽂件)。
listen 1935;
max_connections 1000;
srs_log_tank file;
srs_log_file ./objs/srs.log;
http_api {
enabled on;
listen 1985;
}
http_server {
enabled on;
listen 8081; # http监听端⼝,注意⾃⼰配置的端⼝
dir ./objs/nginx/html;
}
stats {
network 0;
disk sda sdb xvda xvdb;
}
vhost __defaultVhost__ {
# hls darren
hls {
enabled on;
hls_path ./objs/nginx/html;
hls_fragment 10;
hls_window 60;
}
# http-flv darren
http_remux {
enabled on;
mount [vhost]/[app]/[stream].flv;
hstrs on;
}
}
第四步,启动SRS。
./objs/srs -c conf/srs.conf
ubuntu@VM-0-13-ubuntu:~/0voice/media/srs.3.0-20200720/trunk$ ./objs/srs -c conf/srs.conf
后台运⾏结果
[2020-07-20 17:34:48.061][Trace][30433][0] XCORE-SRS/3.0.141(OuXuli)
[2020-07-20 17:34:48.061][Trace][30433][0] config parse complete

确认是否已经正常启动
ubuntu@VM-0-13-ubuntu:~/0voice/media/srs.3.0-20200720/trunk$ sudo ps-ef | grep srs
ubuntu 30435 1 0 17:34 pts/0 00:00:00 ./objs/srs -c conf/srs.conf
显示到ubuntu 30435 1 0 17:34 pts/0 00:00:00 ./objs/srs -c conf/srs.conf
安全退出正在运⾏的srs
sudo kill -SIGQUIT srs_pid
默认是后台启动的⽅式,如果是要⽅便GDB调试则需要修改配置⽂件为前台启动。
listen 1935;
max_connections 1000;
#srs_log_tank file;
#srs_log_file ./objs/srs.log;
# 前台运⾏
daemon off;
# 打印到终端控制台
srs_log_tank console;
http_api {
enabled on;
listen 1985;
}
http_server {
enabled on;
listen 8081; # http监听端⼝
dir ./objs/nginx/html;
}
stats {
network 0;
disk sda sdb xvda xvdb;
}
vhost __defaultVhost__ {
# hls darren
hls {
enabled on;
hls_path ./objs/nginx/html;
hls_fragment 10;
hls_window 60;
}
# http-flv darren
http_remux {
enabled on;
mount [vhost]/[app]/[stream].flv;
hstrs on;
}
}
执⾏⽅法:
./objs/srs -c conf/srs.conf
在终端运⾏,log也在终端显示
