openssl 1.0 对应libevent2.0.* , openssl1.1对应libevent2.1.*

如下安装libevent-2.0.21, libevent-2.1*版本类似

wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
tar zxvf libevent-2.0.21-stable.tar.gz
cd libevent-2.0.21-stable && ./configure
make && make install
2.  编译安装coturn
git clone https://github.com/coturn/coturn
cd coturn 
./configure   #
make install
which turnserver #安装目录在/usr/local/bin/turnserver
3. 配置
cd /usr/local/etc/
cp turnserver.conf.default turnserver.conf
openssl req -x509 -newkey rsa:2048 -keyout  /usr/local/etc/turn_server/turn_server_pkey.pem -out  /usr/local/etc/turn_server/turn_server_cert.pem -days 99999 -nodes 
code\vi  /usr/local/etc/turnserver.conf

其他配置仔细阅读turnserver.conf
4. 启动
turnserver  -help      #查看启动命令
turnserver  -u zzh:123456
turnserver  -o -u zzh:123456      #daemon方式启动
