配置CDH的软件包 parcels(namenode01)
CM安装成功之后,接下来我们就可以通过CM安装CDH的方式构建企业大数据平台。所以首先需要把CDH的parcels包下载到CM主服务器上。
1 [root@master ~]# cd /opt/cloudera/parcel-repo 2 3 [root@master ~]# wget https://archive.cloudera.com/cdh6/6.0.1/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel 4 5 [root@master ~]# wget https://archive.cloudera.com/cdh6/6.0.1/parcels/manifest.json 6 7 [root@master ~]# wget https://archive.cloudera.com/cdh6/6.0.1/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha256 8 9 [root@master ~]# mv CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha256 CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha
注意!上面最好指定ip,切勿使用hostname很容易出现问题
也可以执行下面的操作
在manifest.json文件中,找到对应版本的秘钥,复制到.sha文件中
1 [root@master ~]# echo "2e650f1f1ea020a3efc98a231b85c2df1a50b030" > CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha 2 3 修改属主属组 4 5 [root@master ~]# chown cloudera-scm.cloudera-scm /opt/cloudera/parcel-repo/ * 6 启动 Cloudera Manager Server[master] 7 [root@master ~]# systemctl start cloudera-scm-server 8 如果启动中有什么问题,可以查看日志。[master] 9 [root@master ~]# tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
浏览器打开:IP:7180
1)登录、
账号:admin
密码:admin
2)选择部署版本
选择免费60天测试,正式版等可以实现需求在进行选择。
3)勾选上需要安装的主机
全部勾选
4)部署CDH
可以看到所下载并安装的CDH版本表示前面部署成功,否则需要在线下载。
5)前面配置无误则无须下载,否则表示前面配置有误。分发可能需要一段时间,视集群大小而定(此时集群一定要保证Master可以免密码登录到其它机器上)。
6)检查集群状态
检查集群的状况,可根据提示信息修改配置并重新检查。
a、cdh 托管主机之间的 Java 版本不一致
.......
有些地方忘记了,自行百度一下,前边步骤对了问题不大
7)选择需要安装的组件,可自定义安装。 这个可以选择少点,安装好CM之后可以慢慢添加服务。
8)给集群各个节点分配角色,目前所知道需要注意的地方是HBase Thrift Server不要为空,否则Hue无法访问HBase。主要看hive的角色
9)设置mysql连接。
注意: 这里很容易报错,都是表权限、名称、密码的错误。
10)下一步
后面的一路“继续”下去即可。安装所需时间较长,请耐心等待。
后续服务自行安装
检查主机正确性:
从CDH 6开始,PostgreSQL支持的Hue要求Psycopg2版本至少为2.5.4,有关更多信息,请参见文章。以下主机缺少Psycopg2库的兼容版本
安装Psycopg2
pip3 install psycopg2==2.5.4
没有PIP3 自行安装 python
Hive错误,connector连接错误
cp -r mysql-connector-java-5.1.41.jar /usr/share/java/mysql-connector-java.jar
Cloudera 建议将 /proc/sys/vm/swappiness 设置为 0。当前设置为 60。
sysctl vm.swappiness=0 echo 0 > /proc/sys/vm/swappiness echo never > /sys/kernel/mm/transparent_hugepage/defrag echo never > /sys/kernel/mm/transparent_hugepage/enabled
Exception in thread "main" java.lang.AbstractMethodError: com.mysql.jdbc.JDBC4Connection.getSchema()Ljava/lang/String;
解决:
1 wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz 2 3 tar zxvf mysql-connector-java-5.1.46.tar.gz 4 5 mkdir -p /usr/share/java/ cd mysql-connector-java-5.1.46 6 7 cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
