1.修改 apt-get 源 sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak 更改源： sudo gedit /etc/apt/sources.list deb https://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse ##測試版源 deb https://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse # 源碼 deb-src https://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb-src https://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb-src https://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb-src https://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse ##測試版源 deb-src https://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse 2.更新源 sudo apt-get update 3.修改系统放开root用户 进入到/usr/share/lightdm/lightdm.conf.d/目录，使用gedit 50-unity-greeter.conf &命令打开50-unity-greeter.conf 文件， 在打开文件中添加如下信息，来设置登录时可以选择用户登录，如下所示： user-session=ubuntu greeter-show-manual-login=true all-guest=false 4.安装ssh服务端 sudo apt-get install openssh-server 打开"终端窗口"，输入"sudo gedit /etc/ssh/sshd_config"-->回车-->把配置文件中的"PermitRootLogin without-password"加一个"#"号,把它注释掉-->再增加一句"PermitRootLogin yes"-->保存，修改成功。 5.安装git支持 apt-get install git 6.安装nginx sudo apt-get install nginx 7.添加软件库 sudo vim /etc/apt/sources.list 在文件的最下面加上： deb https://download.jitsi.org stable/ 8.添加官方的key wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add - 更新包列表 sudo apt-get update 9.安装 sudo apt-get -y install jitsi-meet 出现第一个界面时输入本机的ip或者是域名 出现第二个界面时，选择第一个，自动生成一个证书 10.创建nginx软连接 ln -s /etc/nginx/sites-available/jitsi.php2.cc.conf /etc/nginx/conf.d/jitsi.php2.cc.conf 此处jitsi.php2.cc是我自己的域名，需要换成你的ip或域名。 11.重启nginx sudo service nginx restart 如果出现如下错误： Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details. 查一下日志： vim /var/log/nginx/error.log 如果日志中是这个错误： [emerg] 14443#14443: "server_names_hash_bucket_size" directive is duplicate in /etc/nginx/sites-enabled/192.168.1.55.conf:1 修改一下/etc/nginx/conf.d/jitsi.php2.cc.conf这个文件即可： sudo vim /etc/nginx/conf.d/jitsi.php2.cc.conf 将最上面的一行注释掉： server_names_hash_bucket_size 64; 然后重启nginx服务 12.如果是内网在外网访问，需映射端口： TCP 443 (if running web server and jvb on same machine then forward and TCP 4443) and UDP 10000. 并修改文件/etc/jitsi/videobridge/sip-communicator.properties: 添加 org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address> org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address> 例如： org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=192.168.70.61 org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=124.128.231.151 打开浏览器，访问地址：https://jitsi.php2.cc 需注意一点，Android端如果采用官方提供的SDK，自己的域名或IP不能使用https访问，否则会提示：无法连接，让检查网络连接。可更改成http的测试。正式使用建议https，不过需要构建自己的SDK。
