（個人覺得可以利用這個來進一步搭建VPN，有興趣的可以試試）

由于國內通訊都被監控，所以WebRTC是不能直接P2P的，都需要中繼服務作為轉發的，所以在國內使用WebRTC是需要搭建中繼服務。

安裝：
版本：turnserver-3.2.3.95.tar.gz??系統環境：centos

下載必要庫

yum install -y make auomake gcc cc gcc-c++ wget yum install -y openssl-devel libevent libevent-devel mysql-devel mysql-server wget?https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz tar xvfz libevent-2.0.21-stable.tar.gz cd libevent-2.0.21-stable && ./configure make && make install && cd ..

下載turnserver-3.2.3.95.tar.gz并安裝

wget?http://turnserver.open-sys.org/downloads/v3.2.3.95/turnserver-3.2.3.95.tar.gz tar -xvzf turnserver-3.2.3.95.tar.gz cd turnserver-3.2.3.95 ./configure make && make install

安裝后，配置turnserver.conf和turnuserdb.conf
啟動

turnserver -L <public_ip_address> -c turnserver.conf -o -a -b turnuserdb.conf -f -r <system_domain_name>

The value of this option # will be the address of the alternate server for UDP & TCP service in form of # <ip>[:<port>]. The server will send this value in the attribute # ALTERNATE-SERVER, with error 300, on ALLOCATE request, to the client. # Client will receive only values with the same address family # as the client network endpoint address family. # See RFC 5389 and RFC 5766 for ALTERNATE-SERVER functionality description. # The client must use the obtained value for subsequent TURN communications. # If more than one --alternate-server options are provided, then the functionality # can be more accurately described as "load-balancing" than a mere "redirection". # If the port number is omitted, then the default port # number 3478 for the UDP/TCP protocols will be used. # Colon (?characters in IPv6 addresses may conflict with the syntax of # the option. To alleviate this conflict, literal IPv6 addresses are enclosed # in square brackets in such resource identifiers, for example: # [2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478 . # Multiple alternate servers can be set. They will be used in the # round-robin manner. All servers in the pool are considered of equal weight and # the load will be distributed equally. For example, if we have 4 alternate servers, # then each server will receive 25% of ALLOCATE requests. A alternate TURN server # address can be used more than one time with the alternate-server option, so this # can emulate "weighting" of the servers. # # 選項設置"redirection"模式。這個選項的值將備用服務器的地址UDP和TCP服務形式的<ip>[:<port>]。 # 服務器將發送這個值屬性ALTERNATE-SERVER,錯誤300,在ALLOCATE請求,客戶端。 # 客戶端將只接收和自己相同的地址族的客戶端的值。查看RFC 5389和RFC 5766為ALTERNATE-SERVER的功能描述。 # 客戶端必須使用獲得的值為隨后的TURN通信。如果不止一個——alternate-server選項提供,那么功能可以更準確 # 地描述為"load-balancing",而不僅僅是一個"redirection"。如果端口號省略,那么為UDP/TCP協議，使用默認端 # 口號是3478。冒號(在IPv6地址字符可能與選項的語法沖突。緩解這種沖突,文字IPv6地址包含在方括號在這種 # 資源標識符,例如[2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478 。 # 可以設置多個備用服務器。他們將用于循環的方式。所有服務器池中被認為是平等的重量和載荷將平均分配的原則。 # 例如,如果我們有4個備用服務器,每個服務器將獲得25%的分配請求。備用TURN服務器地址可以使用超過一次 # alternate-server選項,所以這可以效仿的"weighting"服務器。 # # Examples: #alternate-server=1.2.3.4:5678 #alternate-server=11.22.33.44:56789 #alternate-server=5.6.7.8 #alternate-server=[2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478 ? ?? ?? ?? ??? # Option to set alternative server for TLS & DTLS services in form of # <ip>:<port>.
