Centos安装janus

centos版本：

[root@localhost passion]# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core) 

安装Centos时候最好选择带界面的，否则网络等不太方便配置。
注：
这里最好先把yum的源换了，建议换163的源（阿里的源gengetopt就找不到）

	换好后执行：
	yum clean
	yum makecache
	yum -y update

修改配置
1、/opt/janus/etc/janus/janus.transport.http.jcfg 里面的 https 改成 true
2、nginx的证书使用janus安装目录下的
