tar xvf v2.0-r2.tar.bz2
cd srs-2.0-r2/trunk
mkdir build
./configure --prefix=/home/longjing/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

rm -f LINUX_4.4.0-116-generic_DBG/md-pic.o; ln -s md.o LINUX_4.4.0-116-generic_DBG/md-pic.o

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configuremake即可。

HLS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_acodec      aac;
        hls_vcodec      h264;
    }
}

启动服务

./objs/srs -c conf/http.hls.conf

reload

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 remove

javascript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
