安装CM
将下载好的cloudera-manager-centos7-cm5.13.0_x86_64.tar.gz解压到主节点的/opt/,解压出来的文件夹为cloudera与cm-5.13.0
为Cloudera Manager建立数据库，此处需要前边下载好的mysql-connector-java-5.1.47-bin.jar
- cp /root/software/mysql-connector-java-5.1.47/mysql-connector-java-5.1.47-bin.jar /usr/java/
- cp /root/software/mysql-connector-java-5.1.47/mysql-connector-java-5.1.47-bin.jar /opt/cm-5.13.0/share/cmf/lib/
主节点执行 执行前确认用户创建无问题(用户创建可能遇到密码策略不符合)
初始化数据库根据数据库的位置不同而不同：下面为数据库与cm 在统一主机
/opt/cm-5.13.0/share/cmf/schema/scm_prepare_database.sh mysql -uroot -p123 scm scm scm
配置Agent（统一复制到其他节点，省的重新做了）
vim /opt/cm-5.13.0/etc/cloudera-scm-agent/config.ini
server_host=cdh01
拷贝文件到其他子节点
scp -r /opt/cm-5.13.0/ root@hywx189:/opt/
scp -r /opt/cm-5.13.0/ root@hywx189:/opt/
所有节点上创建用户 注意家目录的不同/opt/cm-5.13.0/run/cloudera-scm-server/
初始化前将java-mysql 驱动安装到每个节点的给定位置：（见下文测试数据库）
useradd --system --home=/opt/cm-5.13.0/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
useradd --system --home=/opt/cm-5.13.3/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
配置存储目录（主节点貌似）
$ sudo mkdir /var/lib/cloudera-scm-server
$ sudo chown cloudera-scm:cloudera-scm /var/lib/cloudera-scm-server
准备parcels，将CDH相关文件拷贝到主节点/opt/cloudera/parcel-repo/*
注：需要将CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha1改成CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha，否则安装时会重新下载，很重要！！
mv CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha1 CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha
启动
##主节点
/opt/cm-5.13.0/etc/init.d/cloudera-scm-server start
#主节点及其他节点
/opt/cm-5.13.0/etc/init.d/cloudera-scm-agent start
启动需要点时间，可以查看数据库scm中的hosts表，如果里面出现节点信息表示server启动完成
启动成功查看方式：
find / -name cloudera-scm-server.log
tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
grep "Started Jetty server" cloudera-scm-server.log
安装Hadoop集群
启动成功后 浏览器访问：
- http://主节点ip:7180 （用户名、密码：admin）
第一个警告直接在所有节点上执行
- echo 10 > /proc/sys/vm/swappiness
第二个警告按照上面的说明，在所有节点上执行这两条命令
- echo never >/sys/kernel/mm/transparent_hugepage/defrag >> /etc/rc.local
- echo never > /sys/kernel/mm/transparent_hugepage/enabled>> /etc/rc.local
- 同时同一命令添加到 /etc/rc.local 等初始化脚本中，以便在系统重启时予以设置。
测试数据库时
此处hive ，oozie会安装失败，失败信息如下。因为我们使用了MySQL作为hive元数据存储，需要将mysql驱动拷贝到hive和oozie目录下
解决方法（需要在所有节点上执行）
- cp /opt/cm-5.13.0/share/cmf/lib/mysql-connector-java-5.1.47-bin.jar /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/lib/hive/lib/
- cp /opt/cm-5.13.0/share/cmf/lib/mysql-connector-java-5.1.47-bin.jar /var/lib/oozie/
cp /opt/cm-5.7.1/share/cmf/lib/mysql-connector-java-*-bin.jar /opt/cloudera/parcels/CDH-5.7.1-1.cdh5.7.1.p0.11/lib/hive/lib/
cp /opt/cm-5.7.1/share/cmf/lib/mysql-connector-java-*-bin.jar /opt/cloudera/parcels/CDH-5.7.1-1.cdh5.7.1.p0.11/lib/oozie/lib/
cp /opt/cm-5.7.1/share/cmf/lib/mysql-connector-java-*-bin.jar /var/lib/oozie/
初始化 yum安装的scm_prepare_database.sh 位置
cd /usr/share/cmf/lib/
mv /usr/share/java/mysql-connector-java-5.1.46-bin.jar .
安装后节点也需要安装
cd /usr/share/cmf/lib/
mv /usr/share/java/mysql-connector-java-5.1.46-bin.jar .
安装MySQL JDBC驱动程序
从下载的文件中提取JDBC驱动程序JAR文件。例如：
tar zxvf mysql-connector-java-5.1.46.tar.gz
将重命名的JDBC驱动程序复制到 /usr/share/java/。如果目标目录尚不存在，请创建它。例如：
sudo mkdir -p /usr/share/java/
cd mysql-connector-java-5.1.46
sudo cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
sudo cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java-5.1.46-bin.jar
cdh 也需要驱动
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib
hive 数据库也需要
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hive/lib
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hive/lib
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/oozie/lib
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hue/lib
scp mysql-connector-java-5.1.46-bin.jar foo-2:/var/lib/oozie
scp mysql-connector-java-5.1.46-bin.jar foo-2:/var/lib/hue
另外如果想添加新的主机，必须要先启动新主机上的agent服务，否则新主机不能被发现，要重新下载cm-agent，很麻烦。安装新的节点以后，记得运行"部署客户端"命令。
yum安装cm

CM安装
[root@foo-1 yum.repos.d]# cat cloudera-manager.repo
[clouderamanager]
name=Cloudera Manager
baseurl=http://192.168.2.113/cm-5.13.3/
gpgkey=http://192.168.2.113/cm-5.13.3/RPM-GPG-KEY-cloudera
enabled = 1
gpgcheck = 0
install the Cloudera Manager packages.
在管理节点安装cloudera-manager-daemons cloudera-manager-server
#RHEL, if you have a yum repo configured
sudo yum install cloudera-manager-daemons cloudera-manager-server
sudo yum install cloudera-manager-agent
#On all hosts, run the following command to install the Cloudera Manager agent:
在子节点，安装管理客户端
sudo yum install cloudera-manager-daemons cloudera-manager-agent
*** 在所有节点修改管理代理连接管理服务器的主机名
On all hosts, configure the Cloudera Manager Agent to point to the Cloudera Manager Server by setting the following properties in the /etc/cloudera-scm-agent/config.ini configuration file:
server_host Name of the host where Cloudera Manager Server is running.
server_port Port on the host where Cloudera Manager Server is running.
sed -i 's/server_host=localhost/server_host=cdh-1/' /etc/cloudera-scm-agent/config.ini
数据库连接程序
初始化 yum安装的scm_prepare_database.sh 位置
mkdir /usr/share/java/ && cd /usr/share/java/
curl -O http://192.168.2.113/mysql-connector-java/mysql-connector-java-5.1.46.tar.gz
mkdir /usr/share/java/
cp mysql-connector-java-5.1.46-bin.jar mysql-connector-java.jar
chmod 755 mysql-connector-java-5.1.46-bin.jar mysql-connector-java.jar
cp mysql-connector-java-5.1.46-bin.jar mysql-connector-java.jar /usr/share/cmf/lib/
mkdir /usr/share/java/
初始化数据库：
/usr/share/cmf/schema/scm_prepare_database.sh mysql cm -hlocalhost -uroot -pxxxx@123.com --scm-host cdh-1 scm scm scm
所有节点运行管理代理
管理节点
systemctl start cloudera-scm-server
systemctl start cloudera-scm-agent
判断是否启动成功
find / -name cloudera-scm-server.log
tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
grep "Started Jetty server" cloudera-scm-server.log
子节点
systemctl start cloudera-scm-agent
安装后节点也需要安装
cd /usr/share/cmf/lib/
mv /usr/share/java/mysql-connector-java-5.1.46-bin.jar .
cdh 也需要驱动
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib
hive 数据库也需要
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hive/lib
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib
scp mysql-connector-java-5.1.46-bin.jar foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hive/lib

问题
据说5.7版本数据开启GTID会导致cdh初始化数据库失败
在线开启步骤：
1、要求：
（1）必须是5.7.6版本以上的mysql
（2）GTID状态为OFF
2、开启步骤：
（1）：SET GLOBAL ENFORCE_GTID_CONSISTENCY = 'WARN';
（2）：SET GLOBAL ENFORCE_GTID_CONSISTENCY = 'ON';
（3）：SET GLOBAL GTID_MODE = 'OFF_PERMISSIVE';
（4）：SET GLOBAL GTID_MODE = 'ON_PERMISSIVE';
（5）：SET GLOBAL GTID_MODE = 'ON';
3、要永久启用，在my.cnf配置文件中添加参数：
gtid-mode=ON
enforce-gtid-consistency
在线关闭步骤：
1、要求：
（1）必须是5.7.6版本以上的mysql
（2）GTID状态为OFF
2、关闭步骤：
（1）：stop slave;
（2）：SET GLOBAL GTID_MODE = 'ON_PERMISSIVE';
（3）：SET GLOBAL GTID_MODE = 'OFF_PERMISSIVE';
（4）：SET GLOBAL GTID_MODE = 'OFF';
注：
每次开启和关闭时，都是这样一个过程：
打开-->过度模式-->完全打开
停止-->过度模式-->完全关闭
