CDH6离线安装

心已赠人 2022-02-24 04:30 356阅读 0赞

本文是在CentOS7.5下进行CDH6集群的完全离线部署。CDH5集群与CDH6集群的部署区别比较大。

说明：本文内容所有操作都是在root用户下进行的。

## 文件下载 ##

首先一些安装CDH6集群的必须文件要先在外网环境先下载好。

### Cloudera Manager 6.0.1 ###

CM6 RPM：[https://archive.cloudera.com/cm6/6.0.1/redhat7/yum/RPMS/x86\_64/][https_archive.cloudera.com_cm6_6.0.1_redhat7_yum_RPMS_x86_64]  
需要下载该链接下的所有RPM文件，由于jdk1.8我在环境准备部分已经手动安装了，所以可以不用下载`RPMS/x86_64/`目录下的jdk包`oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm`，但是其他4个rpm包一定要下载，保存到`cloudera-repos`目录下。

ASC文件：[https://archive.cloudera.com/cm6/6.0.1/allkeys.asc][https_archive.cloudera.com_cm6_6.0.1_allkeys.asc]  
同时还需要下载一个asc文件，同样保存到`cloudera-repos`目录下：

1.  `/upload/cloudera-repos/`
2.  `├── allkeys.asc`
3.  `├── cloudera-manager-agent-6.0.1-610811.el7.x86_64.rpm`
4.  `├── cloudera-manager-daemons-6.0.1-610811.el7.x86_64.rpm`
5.  `├── cloudera-manager-server-6.0.1-610811.el7.x86_64.rpm`
6.  `└── cloudera-manager-server-db-2-6.0.1-610811.el7.x86_64.rpm`
7.  ``
8.  `0 directories, 4 files`

### MySQL JDBC驱动 ###

要求使用5.1.26以上版本的jdbc驱动，可[点击这里][Link 1]直接下载`mysql-connector-java-5.1.47.tar.gz`

### CDH 6.0.1 ###

CDH6 Parcels：[https://archive.cloudera.com/cdh6/6.0.1/parcels/][https_archive.cloudera.com_cdh6_6.0.1_parcels]  
需要下载`CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel`和`manifest.json`这两个文件

## 配置Cloudera Manager yum库 ##

注意：不要尝试使用FTP搭建CM的YUM库！

首先安装`httpd`和`createrepo`：  
`yum -y install httpd createrepo`  
启动`httpd`服务并设置开机自启动：  
`systemctl start httpd`  
`systemctl enable httpd`  
然后进入到前面准备好的存放Cloudera Manager RPM包的目录`cloudera-repos`下：  
`cd /upload/cloudera-repos/`  
生成RPM元数据：  
`createrepo .`

1.  `[root@cdh601 cloudera-repos]# createrepo .`
2.  `Spawning worker 0 with 2 pkgs`
3.  `Spawning worker 1 with 2 pkgs`
4.  `Workers Finished`
5.  `Saving Primary metadata`
6.  `Saving file lists metadata`
7.  `Saving other metadata`
8.  `Generating sqlite DBs`
9.  `Sqlite DBs complete`

然后将`cloudera-repos`目录移动到httpd的html目录下：  
`mv cloudera-repos /var/www/html/`  
确保可以通过浏览器查看到这些RPM包：  
![img][]  
接着在Cloudera Manager Server主机上创建cm6的repo文件（要把哪个节点作为Cloudera Manager Server节点，就在这个节点上创建repo文件）：  
`cd /etc/yum.repos.d`  
`vim cloudera-manager.repo`  
添加如下内容：

1.  `[cloudera-manager]`
2.  `name=Cloudera Manager 6.0.1`
3.  `baseurl=http://cdh601/cloudera-repos/`
4.  `gpgcheck=0`
5.  `enabled=1`

保存，退出,然后执行`yum clean all && yum makecache`命令：  
![img][img 1]

## 安装Cloudera Manager Server ##

这一步只需要在CM Server节点上操作。  
执行下面的命令：  
`yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server`  
将会需要很多依赖包，所以说还是有必要搭一个局域网内yum源的：  
![img][img 2]

## 配置本地Parcel存储库 ##

Cloudera Manager Server安装完成后，进入到本地Parcel存储库目录：  
`cd /opt/cloudera/parcel-repo`  
将第一部分下载的CDH Parcel文件（`CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel`和`manifest.json`）上传至该目录下，然后执行命令生成sha文件：  
`sha1sum CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel | awk '{ print $1 }' > CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha`  
然后执行下面的命令修改文件所有者：  
`chown -R cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo/*`  
最终`/opt/cloudera/parcel-repo`目录内容如下：  
![img][img 3]

## 安装数据库 ##

MySQL的安装在环境准备部分中已经有说明，这里就跳过MySQL安装了。

### 数据库配置 ###

CDH官方给的有一份推荐的MySQL的配置内容：

1.  `[mysqld]`
2.  `datadir=/var/lib/mysql`
3.  `socket=/var/lib/mysql/mysql.sock`
4.  `transaction-isolation = READ-COMMITTED`
5.  `# Disabling symbolic-links is recommended to prevent assorted security risks;`
6.  `# to do so, uncomment this line:`
7.  `symbolic-links = 0`
8.  ``
9.  `key_buffer_size = 32M`
10. `max_allowed_packet = 32M`
11. `thread_stack = 256K`
12. `thread_cache_size = 64`
13. `query_cache_limit = 8M`
14. `query_cache_size = 64M`
15. `query_cache_type = 1`
16. ``
17. `max_connections = 550`
18. `#expire_logs_days = 10`
19. `#max_binlog_size = 100M`
20. ``
21. `#log_bin should be on a disk with enough free space.`
22. `#Replace '/var/lib/mysql/mysql_binary_log' with an appropriate path for your`
23. `#system and chown the specified folder to the mysql user.`
24. `log_bin=/var/lib/mysql/mysql_binary_log`
25. ``
26. `#In later versions of MySQL, if you enable the binary log and do not set`
27. `#a server_id, MySQL will not start. The server_id must be unique within`
28. `#the replicating group.`
29. `server_id=1`
30. ``
31. `binlog_format = mixed`
32. ``
33. `read_buffer_size = 2M`
34. `read_rnd_buffer_size = 16M`
35. `sort_buffer_size = 8M`
36. `join_buffer_size = 8M`
37. ``
38. `# InnoDB settings`
39. `innodb_file_per_table = 1`
40. `innodb_flush_log_at_trx_commit = 2`
41. `innodb_log_buffer_size = 64M`
42. `innodb_buffer_pool_size = 4G`
43. `innodb_thread_concurrency = 8`
44. `innodb_flush_method = O_DIRECT`
45. `innodb_log_file_size = 512M`
46. ``
47. `[mysqld_safe]`
48. `log-error=/var/log/mysqld.log`
49. `pid-file=/var/run/mysqld/mysqld.pid`
50. ``
51. `sql_mode=STRICT_ALL_TABLES`

### 配置mysql jdbc驱动 ###

从前面下载好的`mysql-connector-java-5.1.47.tar.gz`包中解压出`mysql-connector-java-5.1.47-bin.jar`文件，将`mysql-connector-java-5.1.47-bin.jar`文件上传至CM Server节点上的`/usr/share/java/`目录下并重命名为`mysql-connector-java.jar`（如果`/usr/share/java/`目录不存在，需要手动创建）：  
`tar zxvf mysql-connector-java-5.1.47.tar.gz`  
`mkdir -p /usr/share/java/`  
`cp mysql-connector-java-5.1.47-bin.jar /usr/share/java/mysql-connector-java.jar`

### 创建CDH所需要的数据库 ###

根据所需要安装的服务参照下表创建对应的数据库以及数据库用户，数据库必须使用utf8编码，创建数据库时要记录好用户名及对应密码：

Cloudera Manager Server scm scm Activity Monitor amon amon Reports Manager rman rman Hue hue hue Hive Metastore Server metastore hive Sentry Server sentry sentry Cloudera Navigator Audit Server nav nav Cloudera Navigator Metadata Server navms navms Oozie oozie oozie

我这里就先创建4个数据库及对应用户：

1.  `mysql> CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;`
2.  `Query OK, 1 row affected (0.11 sec)`
3.  ``
4.  `mysql> CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;`
5.  `Query OK, 1 row affected (0.00 sec)`
6.  ``
7.  `mysql> CREATE DATABASE rman DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;`
8.  `Query OK, 1 row affected (0.00 sec)`
9.  ``
10. `mysql> CREATE DATABASE metastore DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;`
11. `Query OK, 1 row affected (0.00 sec)`
12. ``
13. `mysql> GRANT ALL ON scm.* TO 'scm'@'%' IDENTIFIED BY 'scm';`
14. `Query OK, 0 rows affected, 1 warning (0.16 sec)`
15. ``
16. `mysql> GRANT ALL ON amon.* TO 'amon'@'%' IDENTIFIED BY 'amon';`
17. `Query OK, 0 rows affected, 1 warning (0.00 sec)`
18. ``
19. `mysql> GRANT ALL ON rman.* TO 'rman'@'%' IDENTIFIED BY 'rman';`
20. `Query OK, 0 rows affected, 1 warning (0.00 sec)`
21. ``
22. `mysql> GRANT ALL ON metastore.* TO 'hive'@'%' IDENTIFIED BY 'hive';`
23. `Query OK, 0 rows affected, 1 warning (0.00 sec)`
24. ``
25. `mysql> FLUSH PRIVILEGES;`
26. `Query OK, 0 rows affected (0.00 sec)`

查看授权是否正确：

1.  `mysql> SHOW GRANTS FOR 'scm'@'%';`
2.  `+----------------------------------------------+`
3.  `| Grants for scm@% |`
4.  `+----------------------------------------------+`
5.  `| GRANT USAGE ON *.* TO 'scm'@'%' |`
6.  ``| GRANT ALL PRIVILEGES ON `scm`.* TO 'scm'@'%' |``
7.  `+----------------------------------------------+`
8.  `2 rows in set (0.00 sec)`
9.  ``
10. `mysql> SHOW GRANTS FOR 'amon'@'%';`
11. `+------------------------------------------------+`
12. `| Grants for amon@% |`
13. `+------------------------------------------------+`
14. `| GRANT USAGE ON *.* TO 'amon'@'%' |`
15. ``| GRANT ALL PRIVILEGES ON `amon`.* TO 'amon'@'%' |``
16. `+------------------------------------------------+`
17. `2 rows in set (0.00 sec)`
18. ``
19. `mysql> SHOW GRANTS FOR 'rman'@'%';`
20. `+------------------------------------------------+`
21. `| Grants for rman@% |`
22. `+------------------------------------------------+`
23. `| GRANT USAGE ON *.* TO 'rman'@'%' |`
24. ``| GRANT ALL PRIVILEGES ON `rman`.* TO 'rman'@'%' |``
25. `+------------------------------------------------+`
26. `2 rows in set (0.00 sec)`
27. ``
28. `mysql> SHOW GRANTS FOR 'hive'@'%';`
29. `+----------------------------------------------------------+`
30. `| Grants for metastore@% |`
31. `+----------------------------------------------------------+`
32. `| GRANT USAGE ON *.* TO 'hive'@'%' |`
33. ``| GRANT ALL PRIVILEGES ON `metastore`.* TO 'hive'@'%' |``
34. `+----------------------------------------------------------+`
35. `2 rows in set (0.00 sec)`

## 设置Cloudera Manager 数据库 ##

Cloudera Manager Server包含一个配置数据库的脚本。

*  mysql数据库与CM Server是同一台主机  
    执行命令：`/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm`  
    ![img][img 4]
 *  mysql数据库与CM Server不在同一台主机上  
    执行命令：`/opt/cloudera/cm/schema/scm_prepare_database.sh mysql -h <mysql-host-ip> --scm-host <cm-server-ip> scm scm`

## 安装CDH节点 ##

### 启动Cloudera Manager Server服务 ###

`systemctl start cloudera-scm-server`  
然后等待Cloudera Manager Server启动，可能需要稍等一会儿，可以通过命令`tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log`去监控服务启动状态。

当看到`INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server.`日志打印出来后，说明服务启动成功，可以通过浏览器访问Cloudera Manager WEB界面了。

### 访问Cloudera Manager WEB界面 ###

打开浏览器，访问地址：`http://<server_host>:7180`，默认账号和密码都为admin：  
![img][img 5]

### 欢迎页面 ###

首先是Cloudera Manager的欢迎页面，点击页面右下角的【继续】按钮进行下一步：  
![img][img 6]

### 接受条款 ###

勾选接受条款，点击【继续】进行下一步：  
![img][img 7]

### 版本选择 ###

这里我就选择免费版了：  
![img][img 8]

### 第二个欢迎界面 ###

选择版本以后会出现第二个欢迎界面，不过这个是安装集群的欢迎页：  
![img][img 9]

### 选择主机 ###

这一步是要搜索并选择用于安装CDH集群的主机，在主机名称后面的输入框中输入各个节点的hostname，中间使用英文逗号分隔开，然后点击搜索，在结果列表中勾选要安装CDH的节点即可：  
![img][img 10]

### 指定存储库 ###

#### Cloudera Manager Agent ####

这里选择自定义，填写上面使用httpd搭建好的Cloudera Manager YUM 库URL：  
![img][img 11]

#### CDH and other software ####

如果我们之前的【配置本地Parcel存储库】步骤操作无误的话，这里会自动选择【使用Parcel】，并加载出CDH版本，确认无误后点击【继续】：  
![img][img 12]

### JDK安装选项 ###

这一步骤我就不再勾选安装JDK了，因为我在环境准备部分已经安装过了。取消勾选，然后继续：  
![img][img 13]

### SSH登录配置 ###

用于配置集群主机之间的SSH登录，填写root用户的密码，根据集群配置填写合适的【同时安装数量】值即可：  
![img][img 14]

### 安装Agent ###

到这一步会自动进行节点Agent的安装，稍等一会儿，即可安装完成：  
![img][img 15]  
![img][img 16]

### 安装Parcels ###

这一步同样是自动安装，分配步骤的速度主要取决于网络环境，耐心等待即可（我的3台虚拟机性能实在是太差了，这一步等了好久）：  
![img][img 17]  
![img][img 18]

### 主机检查 ###

等待检查完成即可：  
![img][img 19]

## 安装CDH集群 ##

### 选择服务类型 ###

这里我选择自定义服务，HDFS，Hive，Yarn：  
![img][img 20]

### 角色分配 ###

CDH会自动给出一个角色分配，如果觉得不合理，我们可以手动调整一下，注意角色分配均衡：  
![img][img 21]

### 数据库设置 ###

因为我选择的服务中只有Hive需要数据库，故这里只需要配置Hive的metastore数据库。注意要将mysql的jdbc驱动放到hive metastore主机的`/usr/share/java/`目录下：  
![img][img 22]

到这里CDH集群的安装基本上就已经完成了。
