前言：
由于搭建的服务器是公司买的阿里云服务器，运维组还做了安全策略配置，导致遇到的坑比自己搭建的服务器多很多。
以下包必须安装，踩了俩天的坑，还是请教大神帮忙解决了。许多报错日志乱七八糟，但究其原因还是缺包。稍后再贴报错。
apt-get install libmysqlclient-dev
pip install mysql-python
apt-get install python-lxml
apache2是为了下载httpd
apt-get install apache2
CentOS【没测过】
yum install krb5-devel cyrus-sasl-gssapi cyrus-sasl-deve libxml2-devel libxslt-devel mysql mysql-devel openldap-devel python-devel python-simplejson sqlite-devel
yum -y install httpd
yum -y install mod_ssl
过程中踩过的坑

hostname invalid
CDH搭建了三次，这个问题在第二次出现了，环境Centos7+CDH5.14.4。这个问题没有解决，查询了一大堆之后，只是说hostname没有配置好，但我能ping的通，telnet通。之后由于业务原因，要求我换阿里云服务器搭建。我在第三次搭建的时候，我换了Ubuntu16.04+CDH5.15.1。搭建之前我先确保了hostname文件、hosts文件已配置好，能ping通。然后执行python -c 'import socket; print socket.getfqdn(), socket.gethostbyname(socket.getfqdn())，查看是否一致。至此往后搭建就没有出现过这个问题了。
PS：环境最好能一次成功，后来删除增加弄乱了，会非常复杂。

分析过程：首先单独拿出来执行/opt/cm-5.15.1/run/cloudera-scm-agent/process/51-HUE-test-db-connection/altscript.sh sec-2-password，报错，发现JAVA_HOME环境变量找不到，修改之后。再次执行，还是报错，提示密码不能为空。可以判断出来是密码的问题，后面也找到对应文件硬编码文件加了我本机的密码，再次整个执行，报错就简单了，提示缺少包。我的问题是没有安装mysql客户端，也就是前面的apt-get install libmysqlclient-dev。

无法接收到agent检测信号
1、Python文件不匹配；参考http://www.cnblogs.com/lion.net/archive/2014/09/02/3950619.html中_io的设置
2、日志文件不存在，在config.ini中把log_file放开
3、/etc/hosts/中主机和ip配置问题
4、防火墙是否关闭，ubuntu是ufw disable
5、端口配置，config.ini中端口是否配置的为7182
6、集群时间是否同步，安装ntp同步时间
7、ssh私钥的问题-----我现在正在查这个问题呢，前边都配完了，但是仍然无法检测到信号，我没有使用私钥，不知道是不是跟这个有关系
上述问题是我百度到的，我第二次安装遇到了这个问题，但没有解决就让我换机子重新搭了，应该是公司运维小伙伴对hosts做了什么手脚。第三次搭建，我先将节点的agent都起好了，才进入安装界面，这样就直接跳过新主机安装，直接进行分配。
