CDH操作(01)--Cloudera Manager6.0安装(只需要在NODE1做)

前提：

以下操作都是在root用户下操作完成的

----------------------------------------------------------------------------------------

Cloudera Manager安装(只需要在NODE1做)
    1.配置本地repo源
        1.下载CM6.0的安装包，地址为：
            https://archive.cloudera.com/cm6/6.0.0/redhat7/yum/RPMS/x86_64/cloudera-manager-agent-6.0.0-530873.el7.x86_64.rpm
            https://archive.cloudera.com/cm6/6.0.0/redhat7/yum/RPMS/x86_64/cloudera-manager-daemons-6.0.0-530873.el7.x86_64.rpm
            https://archive.cloudera.com/cm6/6.0.0/redhat7/yum/RPMS/x86_64/cloudera-manager-server-6.0.0-530873.el7.x86_64.rpm
            https://archive.cloudera.com/cm6/6.0.0/redhat7/yum/RPMS/x86_64/cloudera-manager-server-db-2-6.0.0-530873.el7.x86_64.rpm
            https://archive.cloudera.com/cm6/6.0.0/redhat7/yum/RPMS/x86_64/oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm
            https://archive.cloudera.com/cm6/6.0.0/allkeys.asc
                 
        2.下载CDH6.0的安装包，地址为：
            https://archive.cloudera.com/cdh6/6.0.0/parcels/
            https://archive.cloudera.com/cdh6/6.0.0/parcels/CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel
            https://archive.cloudera.com/cdh6/6.0.0/parcels/CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel.sha256
            https://archive.cloudera.com/cdh6/6.0.0/parcels/manifest.json

----------------------------------------------------------------------------------------

        3.cdh6.0.0 和 cm6.0.0
            mkdir /root/cdh6.0.0   把 CDH 6.0.0 的三个文件放到/root/cdh 6.0.0 中，并且注意把sha256后缀的文件名修改为sha
             mkdir /root/cm6.0.0     把 Cloudera Manager 6.0.0  的5个文件放到/root/cm6.0.0 中

----------------------------------------------------------------------------------------

        4.执行createrepo命令生成rpm元数据。
           cd /root/cm6.0.0 
            yum install createrepo
            createrepo . （注意此命令的最后带一个点） 最终 cm6.0目录下多了一个repodata目录
            

        5.配置Web服务器
            将 cdh6.0目录 和 cm6.0目录 移动到/var/www/html目录下, 使得用户可以通过HTTP访问这些rpm包。
            cd /root
            mkdir -p /var/www/html
            mv ./cdh6.0.0/ ./cm6.0.0/ /var/www/html
 
        6.使得用户可以通过HTTP访问这些/var/www/html目录下的文件
            1.yum install httpd  安装httpd服务
            2.systemctl start httpd 启动httpd服务
            3.ps -ef | grep httpd 查看httpd服务是否启动
            4.cd /etc/yum.repos.d/
             mkdir os.repo
             vim os.repo 
             以下为文件内容:    
             [osrepo]
             name=os_repo
             baseurl=http://192.168.242.132/cm6.0.0
             enabled=true
             gpgcheck=false
            5.sudo yum repolist #查看repolist
            6.vim /etc/httpd/conf/httpd.conf 
                修改 /etc/httpd/conf/httpd.conf 配置文件，在<IfModule mime_module>中修改以下内容
                把 AddType application/x-gzip .gz .tgz 第 284 行 修改为 AddType application/x-gzip .gz .tgz .parcel
            7.重启httpd服务 systemctl restart httpd
            8.浏览器即可打开以下链接：
                http://192.168.242.132/cdh6.0.0/
                http://192.168.242.132/cm6.0.0/

备注:可能会出现以下错误提示：
You don’t have permission to access

在centos7下的处理方式；
1.关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service

2.关闭selinux
vim /etc/selinux/config
修改内容：
SELINUX=disabled

 

        7.制作Cloudera Manager的repo源
            1.vim /etc/yum.repos.d/cm.repo 以下为文件内容
                [cmrepo]
                name=cm_repo
                baseurl=http://192.168.242.132/cm6.0.0 
                enable=true
                gpgcheck=false
            2.sudo yum repolist
            3.重启httpd服务 systemctl restart httpd

    2.安装Cloudera Manager Server
        1.安装CM6.0时，请装官方提供的JDK：oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm
            1.第一种方式：(目前使用这种方式即可)
                因为已经配置好repo仓库所以yum时会到192.168.242.132/cm6.0.0目录下找到oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm进行安装
                yum -y install oracle-j2sdk1.8-1.8.0+update141-1.x86_64
                  默认安装在 /usr/java/jdk1.8.0_141-cloudera 
                  vim /etc/profile 文件中内容如下
                    JAVA_HOME=/usr/java/jdk1.8.0_141-cloudera
                        CLASSPATH=.:$JAVA_HOME/lib/tools.jar
                        PATH=$JAVA_HOME/bin:$PATH
                       export JAVA_HOME CLASSPATH PATH
                  重新加载profile配置文件，让配置文件生效：source /etc/profile     
                    检查是否已配置好新的JDK：java -version
                  scp -r /etc/profile root@NODE2:/etc/
                  scp -r /etc/profile root@NODE3:/etc/
            2.第二种方式 
                直接使用 rpm -ivh 命令安装 rpm 文件的方式
                rpm -ivh oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm
                  默认安装在 /usr/java/jdk1.8.0_141-cloudera
        2.通过yum安装Cloudera Manager Server：（Cloudera Manager Server的源 已经配置到了repo库中）
            yum -y install cloudera-manager-server 
            最后一行显示 Complete!
        3.初始化数据库
            /opt/cloudera/cm/schema/scm_prepare_database.sh mysql cm cm password 
            最后一行显示 All done, your SCM database is configured correctly!
        4.启动Cloudera Manager Server
            必须保证MySQL启动了，才能正常启动Cloudera Manager Server：service mysql start
            ps -ef | grep mysql
            systemctl start cloudera-scm-server 启动Cloudera Manager Server
            ps -ef | grep cloudera-scm-server 查看是否启动
            systemctl status cloudera-scm-server 显示 Active: active (running) 
        5.检查端口是否监听
            yum install net-tools 安装 netstat
            netstat -lnpt | grep 7180 要等一段时间启动完全启动成功后，才能看到端口被使用，然后才能真正访问到CM的登录网页
                显示 tcp 0  0 0.0.0.0:7180  0.0.0.0:*  LISTEN  68289/java
        5.通过 192.168.242.132:7180/cmf/login 访问 CM
