Cloudera Manager Server 和 Agent 安装
Yum 安装Yum 网络安装方式，如果你已经配置 yum 源
yum install cloudera-manager-daemons cloudera-manager-server
rpm 包安装
所有服务器都需要的操作：
我们使用 rpm 安装所以其他的依赖包需要使用 yum 安装
yum install bind-utils psmisc libxslt cyrus-sasl-plain cyrus-sasl-gssapi fuse portmap fuse-libs httpd mod_ssl Python-psycopg2 redhat-lsb-core –y
wget https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.15.0/RPMS/x86_64/cloudera-manager-daemons-5.15.0-1.cm5150.p0.62.el7.x86_64.rpm
rpm –ivh cloudera-manager-daemons-5.15.0-1.cm5150.p0.62.el7.x86_64.rpm

下载 server rpm 包

wget https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.15.0/RPMS/x86_64/cloudera-manager-server-db-2-5.15.0-1.cm5150.p0.62.el7.x86_64.rpm
rpm –ihv cloudera-manager-server-5.15.0-1.cm5150.p0.62.el7.x86_64.rpm cloudera-manager-server-db-2-5.15.0-1.cm5150.p0.62.el7.x86_64.rpm
Agent 服务器安装
Wget https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.15.0/RPMS/x86_64/cloudera-manager-agent-5.15.0-1.cm5150.p0.62.el7.x86_64.rpm
Rpm –ivh cloudera-manager-agent-5.15.0-1.cm5150.p0.62.el7.x86_64.rpm
安装MySQL
数据库这一步我们可以找DBA 协助
在server 机安装配置MySQL
sudo yum install mysql-server
设置开机启动
sudo chkconfig mysqld on
启动MySQL service
sudo service mysqld start
设置root用户密码
sudo mysqladmin -u root password 'xxxx'
为Cloudera Manager建立数据库
下载MySQL驱动：
解压把驱动的jar文件mysql-connector-java.jar上传到/usr/share/java/
初始化数据cloudera库
sudo /user/share/cmf/schema/scm_prepare_database.sh mysql cm -hlocalhost -uroot -pmysql@Hadoop0 --scm-host localhost scm mysql@Hadoop:scm:88
如果DBA已经帮我们处理完的数据库的事情，我们需要修改 数据库配置文件
c /etc/cloudear-scm-server/db.properties
com.cloudera.cmf.db.type=mysql
com.cloudera.cmf.db.host=www.mydatabase.com:3306
com.cloudera.cmf.db.name=scm
com.cloudera.cmf.db.user=devuser
com.cloudera.cmf.db.password=Devuser123
com.cloudera.cmf.db.setupType=EXTERNAL
在Master机上启动Cloudera Manager Server
Systemctl start cloudera-scm-server
Systemctl enable cloudera-scm-server
Agent配置在所有机器上配置Master机的主机名
sudo vim /etc/cloudera-scm-agent/config.ini
把server_host设置成Master机的主机名
server_host=192.1687.1.2
启动agent
Systemctl start cloudera-scm-agent
Systemctl enable cloudera-scm-agent
打开Cloudera Manager主页

第一次启动比较慢，可能需要等待几分钟才可以打得开cloudera manager主页。
登录Cloudera Manager
默认用户名密码都是admin，第一次登录成功之后先进入到cloudera manager的安装引导界面：
CDH安装
CDH文件上传
下载 CDH 安装包和 sha 验证文件
