CM安装
1.安装Cloudera manager server,agent
mkdir /opt/cloudera-manager
tar -zxvf cloudera-manager*.tar.gz /opt/cloudera-manager
2.创建用户cloudera-scm
useradd --system --home=/opt/cm-5.14.0/run/cloudera-scm-server/ --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
useradd --system --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
3.配置CM Agent
修改/opt/cm-5.14.0/etc/cloudera-scm-agent/config.ini中的server_host为主节点的主机名。
同步Agent到其他节点
4.配置CM Server数据库
首先需要去MySql的官网下载JDBC驱动，http://dev.mysql.com/downloads/connector/j/，解压后，
找到mysql-connector-java-5.1.45-bin.jar，放到/opt/cm-5.14.0/share/cmf/lib/和/usr/share/java中。并改名字mysql-connector-java.jar
设置mysql jar权限
chmod 777 mysql-connector-java.jar
登录mysql执行下面的语句
去看我的《学习hadoop遇到的问题（安装mysql时，密码找不到）》去添加其他ip的访问权限
cd /opt/cloudera-manager/cm-5.14.0/share/cmf/schema/
./scm_prepare_database.sh mysql -node1 -uroot -p123456 --scm-host node1 scm root 123456
格式：数据库类型，数据库，数据库服务器，用户名，密码，cm server服务器
5.创建parcel用户
server节点
mkdir -p /opt/cloudera/parcel-repo/
chown cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo
mkdir /var/cloudera-scm-server, /var/lib/cloudera-scm-server
chown cloudera-scm:cloudera-scm /var/cloudera-scm-server
agent节点
mkdir -p /opt/cloudera/parcels
chown cloudera-scm:cloudera-scm /opt/cloudera/parcels
6.制作CDH本地源
下载好文件CDH-5.14.0-1.cdh5.14.0.p0.24-el7.parcel，CDH-5.11.1-1.cdh5.11.1.p0.18-el5.parcel.sha1,manifest放到server节点/opt/cloudera/parcel-repo/下
注意：其中CDH-5.11.1-1.cdh5.11.1.p0.18-el5.parcel.sha1 后缀要把1去掉
7.启动CM server，agent
cd /opt/cloudera-manager/cm-5.14.0/etc/init.d/
./cloudera-scm-server start
./cloudera-scm-agent start
