本节开始安装MCU Server。
MCU Server有两种工作模式，一种是通过GPU，一种是通过CPU，由于我用的是虚拟机，所以这里用的是CPU。
MCU Server是自带自签名证书的域名与实际域名不匹配，所以大家要生成自己的证书。
1、权限配置
1.1、/etc/security/limits.conf
* hard nproc unlimited * soft nproc unlimited * hard nofile 163840 * soft nofile 163840 * hard stack 1024 * soft stack 1024
1.2、/etc/pam.d/login
session required pam_limits.so
1.3、/etc/security/limits.d/xx-nproc.conf
* hard nproc unlimited * soft nproc unlimited
1.4、/etc/sysctl.conf
fs.file-max=200000 net.core.rmem_max=16777216 net.core.wmem_max=16777216 net.core.rmem_default=16777216 net.core.wmem_default=16777216 net.ipv4.udp_mem=4096 87380 16777216 net.ipv4.tcp_rmem=4096 87380 16777216 net.ipv4.tcp_wmem=4096 65536 16777216 net.ipv4.tcp_mem=8388608 8388608 16777216
1.5、启用设置
sudo /sbin/sysctl -p ulimit -a
2、解压文件
tar -xf CS_WebRTC_Conference_Server_MCU.v4.1.tgz mv Release-v4.1 /neohope/webrtc/MCU-Release-v4.1
3、编译依赖库
3.1、Cisco OpenH264
cd /neohope/webrtc/MCU-Release-v4.1/video_agent #编译并安装依赖库 install_deps.sh #关闭支持 #uninstall_openh264.sh #开启支持 #install_openh264.sh
3.2、ffmpeg with libfdk_aac
cd /neohope/webrtc/MCU-Release-v4.1/audio_agent compile_ffmpeg_with_libfdkaac.sh mv ffmpeg_libfdkaac_lib/* lib/
4、初始化服务
4.1、生成证书
#生成RSA私钥 openssl genrsa -out ryans-key.pem 2048 Generating RSA private key, 2048 bit long modulus ..........................................................+++ ................................................................................ ........................................+++ e is 65537 (0x10001) #生成CSR(certificate signing request) openssl req -new -sha256 -key ryans-key.pem -out ryans-csr.pem You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [XX]:CN State or Province Name (full name) []:SH Locality Name (eg, city) [Default City]:SH Organization Name (eg, company) [Default Company Ltd]:NEOHOPE Organizational Unit Name (eg, section) []:RD Common Name (eg, your name or your server's hostname) []:172.16.172.80 Email Address []:NEOHOPE@YAHOO.COM Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []: An optional company name []: #生成自签名证书 openssl x509 -req -in ryans-csr.pem -signkey ryans-key.pem -out ryans-cert.pem Signature ok subject=/C=CN/ST=SH/L=SH/O=NEOHOPE/OU=RD/CN=172.16.172.80/emailAddress=NEOHOPE@Y AHOO.COM Getting Private key #转换为p12格式 #openssl pkcs12 -export -in ryans-cert.pem -inkey ryans-key.pem -certfile ca-cert.pem -out ryans.pfx openssl pkcs12 -export -in ryans-cert.pem -inkey ryans-key.pem -out ryans.pfx Enter Export Password: Verifying - Enter Export Password:
4.2、安装证书
cp ryans.pfx ../MCU-Release-v4.1/extras/basic_example/cert/certificate.pfx cp ryans.pfx ../MCU-Release-v4.1/portal/cert/certificate.pfx #cp ryans.pfx ../MCU-Release-v4.1/webrtc_agent/cert/certificate.pfx cp ryans.pfx ../MCU-Release-v4.1/management_console/cert/certificate.pfx #然后分别到basic_example、portal、management_console下面，执行 node initcert.js
5、初始化服务
#非GPU加速 bin/init-all.sh #GPU加速 #bin/init-all.sh --hardware
6、开启服务
bin/start-all.sh

7、测试服务，访问地址
7.1、你可以用浏览器浏览这个页面，可以看到自己的输入和输出视频画面
https://172.16.172.80:3004/
7.2、你可以用多个浏览器浏览这个页面，可以看到多路视频被合并为一个视频画面了。
https://172.16.172.80:3004/
7.3、如果不想合并多路视频，而是直接获取单个视频，可以用这个链接
https://172.16.172.80:3004/?forward=true
7.4、你可以用这个URL加入某个视频会议的房间
https://172.16.172.80:3004/?room=root_id
房间ID，在启动时，会输出到命令行及日志。
7.5、可以进入管理页面
https://172.16.172.80:3300/console/
需要输入Service_ID及Service_KEY。
可以在MCU-Release-v4.1/extras/basic_example/samplertcservice.js，查找这行代码即可得到：
icsREST.API.init('_service_ID_', '_service_KEY_', 'http://localhost:3000/', true);
8、停止服务
