【CDH部署】CDH6.2安装配置第二篇：CDH安装的前期配置

本篇介绍cdh安装之前需要的一些必要配置，当然这些配置也可以用shell脚本来配置。在安装之前请先配置好yum源，在文中用的统一都是阿里源。在安装的时候，要确保主机的内存是4G以上，要不然会无限重启cm服务

 另外2篇传送门：

CDH6.2安装配置第一篇：CDH配置本地http服务

CDH6.2安装配置第三篇：前台页面配置讲解

其他配置的传送门：

LINUX的ssh免密码配置

LINUX之ntp时间同步服务配置

CDH版本：6.2 

系统：centos7（el6是代表centos6系统，centos7则用el7表示）

主机3台：

master.com.cn 192.168.1.110   2C4G

salver1.com.cn 192.168.1.111   1C2G

salver2.com.cn 192.168.1.112  1C2G

yum服务器：yum.com.cn 192.168.1.100。这里如果不知道怎么配置的朋友，可以参考第一篇：https://www.cnblogs.com/yaowentao/p/12296329.html

 

基本配置

1. 主机名在系统安装的配置完毕，如果没有配置，可以进系统在修改

1 $ vi /etc/hostname

2. 配置host文件

1 $ vi /etc/hosts
2 192.168.1.100 yum.com.cn
3 192.168.1.110 master.com.cn
4 192.168.1.111 salver1.com.cn
5 192.168.1.112 salver2.com.cn

3. 关闭防火墙，selinux。配置完后重启

1 $ sudo systemctl disable firewalld        #停止防火墙
2 $ sudo systemctl stop firewalld           #禁止开机启动防火墙
3 
4 $ vi /etc/selinux/config
5 SELINUX=disable　　　　　　　　　　　　　　　　#关闭selinux

 

4. 配置ntp服务与ssh免密码登陆配置，请参考我的另外2篇文档

 ssh免密码配置传送门：https://www.cnblogs.com/yaowentao/p/12300321.html

 ntp配置传送门：https://www.cnblogs.com/yaowentao/p/12300408.html

5. 如果有本地的yum源，就配置。如果没有就使用公网的yum源。

5.1 配置yum 本地库,也可以下载官网的repo文件，一个是从网上下载，一个是从本地yum库下载
1 [cloudera-repo]
2 name=cloudera-repo
3 baseurl=http://192.168.10.225/cloudera-repos/cm6/6.2.1/redhat7/yum/
4 enabled=1
5 gpgcheck=0
5.2 网上yum源，直接下载即可
1 $ sudo wget https://archive.cloudera.com/cm6/6.2.1/redhat7/yum/cloudera-manager.repo -P /etc/yum.repos.d/ 

6. 安装cdh专用jdk（需要在所有主机上都要安装）

1 $ sudo yum -y install oracle-j2sdk1.8

7. 配置本地的mysql数据库，便于存放cdh服务器的一些配置，以及hadoop组件中需要的一些配置，如hive的源数据库。这里一般推荐用mysql，当然oracle等其他的数据库也可以。

  1. 直接用yum源安装
  2. 1 $ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
2 $ sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
3 $ sudo yum update
4 $ sudo yum install mysql-server
5 $ sudo systemctl start mysqld

  3. 配置mysql数据，并进行初始化，设置root密码
  4. $vi /etc/my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
transaction-isolation = READ-COMMITTED
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
symbolic-links = 0


key_buffer_size = 32M
max_allowed_packet = 32M
thread_stack = 256K
thread_cache_size = 64
query_cache_limit = 8M
query_cache_size = 64M
query_cache_type = 1


max_connections = 550
#expire_logs_days = 10
#max_binlog_size = 100M


#log_bin should be on a disk with enough free space.
#Replace '/var/lib/mysql/mysql_binary_log' with an appropriate path for your
#system and chown the specified folder to the mysql user.
log_bin=/var/lib/mysql/mysql_binary_log


#In later versions of MySQL, if you enable the binary log and do not set
#a server_id, MySQL will not start. The server_id must be unique within
#the replicating group.
server_id=1


binlog_format = mixed


read_buffer_size = 2M
read_rnd_buffer_size = 16M
sort_buffer_size = 8M
join_buffer_size = 8M


# InnoDB settings
innodb_file_per_table = 1
innodb_flush_log_at_trx_commit  = 2
innodb_log_buffer_size = 64M
innodb_buffer_pool_size = 4G
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT
innodb_log_file_size = 512M


[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid


sql_mode=STRICT_ALL_TABLES

  5. 配置开机自启动

  6. 1 $ sudo systemctl enable mysqld
2 $ sudo systemctl start mysqld
  7. 初始化mysql，设置root密码
  8.  1 $ sudo /usr/bin/mysql_secure_installation
 2 [...]
 3 Enter current password for root (enter for none):
 4 OK, successfully used password, moving on...
 5 [...]
 6 Set root password? [Y/n] Y
 7 New password:
 8 Re-enter new password:
 9 Remove anonymous users? [Y/n] Y
10 [...]
11 Disallow root login remotely? [Y/n] N
12 [...]
13 Remove test database and access to it [Y/n] Y
14 [...]
15 Reload privilege tables now? [Y/n] Y
16 All done!

     

     

     

  9. 安装mysql的jdbc

  10. 1 $ wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz
2 $ tar zxvf mysql-connector-java-5.1.46.tar.gz
3 
4 $ sudo mkdir -p /usr/share/java/
5 $ cd mysql-connector-java-5.1.46
6 $ sudo cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
  11. 给root授远程登陆权限
  12. 1 mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
2 mysql> FLUSH PRIVILEGES;
  13. 创建cm服务，hadoop组件需要的库。用户统一用root。
  14.  1 CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
 2 GRANT ALL ON scm.* TO 'root'@'%' IDENTIFIED BY '123456';
 3 CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
 4 GRANT ALL ON amon.* TO 'root'@'%' IDENTIFIED BY '123456';
 5 CREATE DATABASE rman DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
 6 GRANT ALL ON rman.* TO 'root'@'%' IDENTIFIED BY '123456';
 7 CREATE DATABASE hue DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
 8 GRANT ALL ON hue.* TO 'root'@'%' IDENTIFIED BY '123456';
 9 CREATE DATABASE metastore DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
10 GRANT ALL ON metastore.* TO 'root'@'%' IDENTIFIED BY '123456';
11 CREATE DATABASE sentry DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
12 GRANT ALL ON sentry.* TO 'root'@'%' IDENTIFIED BY '123456';
13 CREATE DATABASE nav DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
14 GRANT ALL ON nav.* TO 'root'@'%' IDENTIFIED BY '123456';
15 CREATE DATABASE navms DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
16 GRANT ALL ON navms.* TO 'root'@'%' IDENTIFIED BY '123456';
17 CREATE DATABASE oozie DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
18 GRANT ALL ON oozie.* TO 'root'@'%' IDENTIFIED BY '123456';

  15.  安装cm服务器文件

  16. 1 master:
2 $ sudo yum -y install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server
3

     

     

    4 salver:
5 $ sudo yum -y install cloudera-manager-daemons cloudera-manager-agent
     
  17. scm初始化
    1. 　　 
      1 $ sudo /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm root
  18. 完成以上配置，就能正常登陆cm服务器的前台了。下面进入服务器的配置。请看第三篇。
    1. 　　启动cm服务 
      1 $ sudo systemctl start cloudera-scm-server
2 $ sudo tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log

启动成功：
