jitsi-meet Ubuntu16.04 LTS 部署方式
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.z5s.cn.conf /etc/nginx/conf.d/jitsi.z5s.cn.conf
此处jitsi.z5s.cn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/jitsi.z5s.cn.conf:1
修改一下/etc/nginx/conf.d/jitsi.z5s.cn.conf这个文件即可：
sudo vim /etc/nginx/conf.d/jitsi.z5s.cn.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=
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=
例如：
org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=192.178.80.21
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=224.228.231.251
打开浏览器，访问地址：https://jitsi.z5s.cn
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。
