SRS简介
SRS，即Simple-RTMP-Server，是一个开源的视频服务器，出自国人之手。release版本下载地址https://github.com/ossrs/srs/releases，目前的最高版本是v2.0-r2。
源码编译
下载了源码后，我们就可以开始编译了，具体命令如下
tar xvf v2.0-r2.tar.bz2
cd srs-2.0-r2/trunk
mkdir build
./configure --prefix=/home/xugaoxiang/srs/srs-2.0-r2/trunk/build --with-http-api --with-hls --with-http-server --with-ssl --with-stat --with-research --with-dvr --with-http-callback
make
make install如果出现错误

build st-1.9 failed, ret=2修改auto/depends.sh, 搜索关键字st-1.9,找到
_ST_MAKE=linux-debug && _ST_EXTRA_CFLAGS="-DMD_HAVE_EPOLL并将其修改为
_ST_MAKE=linux-debug && _ST_EXTRA_CFLAGS="-DMD_HAVE_EPOLL -fno-stack-protector"再重新configure、make即可。
HLS配置文件
这里给出了HLS使用的配置文件
listen 2935;
max_connections 1000;
daemon on;
srs_log_tank file;
srs_log_level error;
srs_log_file ./objs/srs.log;
http_server {
enabled on;
listen 8081;
dir ./objs/nginx/html;
}
vhost __defaultVhost__ {
hls {
enabled on;
hls_fragment 10;
hls_window 60;
hls_path ./objs/nginx/html;
hls_m3u8_file [app]/[stream].m3u8;
hls_ts_file [app]/[stream]-[seq].ts;
hls_cleanup on;
hls_dispose 30;
hls_on_error continue;
hls_storage disk;
hls_wait_keyframe on;
hls_acodec aac;
hls_vcodec h264;
}
}启动服务
配置文件搞定了，就可以正式启动流媒体服务了
./objs/srs -c conf/http.hls.confreload
如果srs正在正常运行，但是配置文件又有了更新，想要服务无缝重启，可以使用reload操作
killall -1 srs开机自动启动
sudo ln -sf /home/xugaoxiang/build/etc/init.d/srs /etc/init.d/srs
修改srs中的ROOT和CONFIG
ROOT="/home/xugaoxiang/build"
CONFIG="./conf/http.hls.conf"然后在命令行下执行
sudo update-rc.d srs defaults可以先用
sudo /etc/init.d/srs start/stop/restart/status/reload测试一下，正确无误后再重启系统。需要注意的是，只有runlevel是2、3、5、6才可以启动。需要的话，可以到/etc/rc*.d/下进行相应的修改。
如果想要删除srs服务，可以执行
sudo update-rc.d -f srs removejavascript访问出现的跨域问题
修改源码src/app/srs_app_http_conn.cpp，大概是292行
hdr->set("Access-Control-Allow-Origin", "*");
hdr->set("Access-Control-Allow-Methods", "GET, POST, HEAD, PUT, DELETE");
hdr->set("Access-Control-Allow-Headers", "Cache-Control,X-Proxy-Authorization,X-Requested-With,Content-Type");并发测试工具
srs-bench是专门用来测试srs并发的工具，基于state-threads。
git clone https://github.com/ossrs/srs-bench.git
cd srs-bench
./configure
make
