Hive安装部署与配置

Hive安装部署与配置

1.1 Hive安装地址

1)Hive官网地址:

http://hive.apache.org/

2)文档查看地址:

https://cwiki.apache.org/confluence/display/Hive/GettingStarted

3)下载地址:

http://archive.apache.org/dist/hive/

4)github地址:

https://github.com/apache/hive

1.2 Hive安装部署

1)Hive安装及配置

(1)使用rz命令上传

(2)解压到执行目录

tar -zxvf apache-hive-1.2.1-bin.tar.gz -C /opt/module/

(3)修改名称为hive

 mv apache-hive-1.2.1-bin/ hive

(4)修改/opt/module/hive/conf目录下的hive-env.sh.template名称为hive-env.sh

mv hive-env.sh.template hive-env.sh

(5)配置hive-env.sh文件

(a)配置HADOOP_HOME路径

export HADOOP_HOME=/opt/module/hadoop-2.8.4

(b)配置HIVE_CONF_DIR路径

export HIVE_CONF_DIR=/opt/module/hive/conf

注:Hive的log默认存放在/tmp/chenchuan/hive.log目录下(当前用户名下)。

(1)修改hive的log存放日志到/opt/module/hive/logs

(2)修改conf/hive-log4j.properties.template文件名称为hive-log4j.properties

 pwd /opt/module/hive/conf

 mv hive-log4j.properties.template hive-log4j.properties

(3)在hive-log4j.properties文件中修改log存放位置

hive.log.dir=/opt/module/hive/logs

2)Hadoop集群配置

(1)必须启动hdfs和yarn

 sbin/start-dfs.sh

 sbin/start-yarn.sh

(2)在HDFS上创建/tmp和/user/hive/warehouse两个目录并修改他们的同组权限可写

bin/hadoop fs -mkdir /tmp

 bin/hadoop fs -mkdir -p /user/hive/warehouse

 bin/hadoop fs -chmod g+w /tmp

 bin/hadoop fs -chmod g+w /user/hive/warehouse

1.3 MySql安装

官网下载地址

https://dev.mysql.com/downloads/file/?id=471503

 

 检测本地是否有mysql已存在的包

rpm -qa | grep mysql

 

 检测本地是否有mariadb已存在的包

rpm -qa | grep mariadb

 

如果存在,则使用yum命令卸载

mariadb-libs-5.5.56-2.el7.x86_64

yum -y remove mariadb-libs-5.5.56-2.el7.x86_64

rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64

 

创建一个文件夹,上传jar包到/opt/software/mysql

mkdir /opt/software/mysql

 

解压mysql jar包

tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar -C /opt/module/mysql

 

 安装mysql的 server、client、common、libs、lib-compat

rpm -ivh --nodeps mysql-community-server-5.7.19-1.el7.x86_64.rpm

rpm -ivh --nodeps mysql-community-client-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.19-1.el7.x86_64.rpm

 

 查看mysql的服务是否启动

systemctl status mysqld

 Active: inactive (dead)

 

 启动mysql的服务

systemctl start mysqld

 

再次检查mysql的服务是否启动

systemctl status mysqld

   Active: active (running) since Thu 2019-03-21 07:23:08 EDT; 2s ago

 

查看默认生成的密码

cat /var/log/mysqld.log | grep password

2019-03-21T11:23:01.643479Z 1 [Note] A temporary password is generated for root@localhost: iwkJGgd:j6jO

 

登录mysql服务

mysql -uroot -p’然后粘贴上密码’

 

修改mysql密码规则

0 or LOW

长度

1 or MEDIUM

长度、大小写、数字、特殊字符

2 or STRONG

长度、大小写、数字、特殊字符、词典

 

注:以下修改是临时修改

a.密码强度检查等级,0/LOW、1/MEDIUM、2/STRONG

mysql> set global validate_password_policy=0;

Query OK, 0 rows affected (0.05 sec)

 

b.密码至少要包含的小写字母个数和大写字母个数

mysql> set global validate_password_mixed_case_count=0;

Query OK, 0 rows affected (0.00 sec)

 

c.密码至少要包含的数字个数 

mysql> set global validate_password_number_count=3;

Query OK, 0 rows affected (0.00 sec)

 

d.密码至少要包含的特殊字符数

mysql> set global validate_password_special_char_count=0;

Query OK, 0 rows affected (0.00 sec)

 

e.密码最小长度,参数默认为8

它有最小值的限制,最小值为:validate_password_number_count + 密码至少要包含的数字个数validate_password_special_char_count +特殊字符

 (2 * validate_password_mixed_case_count)至少要包含的小写字母个数和大写字母个数

mysql> set global validate_password_length=3;

Query OK, 0 rows affected (0.00 sec)

修改密码:

alter user root@localhost identified by '000000';

flush privileges;

(这两步可以跳过)

 mysql> use mysql;

mysql> SHOW VARIABLES LIKE 'validate_password%';

+--------------------------------------+-------+

| Variable_name                        | Value |

+--------------------------------------+-------+

| validate_password_dictionary_file    |       |

| validate_password_length             | 3     |

| validate_password_mixed_case_count   | 0     |

| validate_password_number_count       | 3     |

| validate_password_policy             | LOW   |

| validate_password_special_char_count | 0     |

+--------------------------------------+-------+

 修改远程登录权限

大家默认的%的位置是localhost,即意味着只能本机访问

 

查询当前user表内root的登录权限:

select host,user from mysql.user;

修改权限为所有%:

update mysql.user set host = '%' where user = 'root';

刷新缓存:

flush privileges;

1.4 Hive元数据配置到MySql

1.4.1 驱动拷贝

1)上传mysql-connector-java-5.1.27-bin.jar到/opt/module/hive/lib/

cp mysql-connector-java-5.1.27-bin.jar /opt/module/hive/lib/

1.4.2 配置MetastoreMySql

1)在/opt/module/hive/conf目录下创建一个hive-site.xml

 touch /opt/module/hive/conf/hive-site.xml

2)根据官方文档配置参数,拷贝数据到hive-site.xml文件中。

https://cwiki.apache.org/confluence/display/Hive/AdminManual+MetastoreAdmin

 

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>

        <property>

          <name>javax.jdo.option.ConnectionURL</name>

          <value>jdbc:mysql://master:3306/hive?createDatabaseIfNotExist=true</value>

          <description>JDBC connect string for a JDBC metastore</description>

        </property>

 

        <property>

          <name>javax.jdo.option.ConnectionDriverName</name>

          <value>com.mysql.jdbc.Driver</value>

        </property>

 

        <property>

          <name>javax.jdo.option.ConnectionUserName</name>

          <value>root</value>

          <description>username to use against metastore database</description>

        </property>

 

        <property>

          <name>javax.jdo.option.ConnectionPassword</name>

          <value>000000</value>

          <description>password to use against metastore database</description>

        </property>

        <property>

                <name>hive.metastore.warehouse.dir</name>

                <value>/user/hive/warehouse</value>

                <description>location of default database for the warehouse</description>

        </property>

        <property>

                <name>hive.cli.print.header</name>

                <value>true</value>

        </property>

 

        <property>

                <name>hive.cli.print.current.db</name>

                <value>true</value>

        </property>

</configuration>

 

3) 配置完毕后,如果启动hive异常,可以重新启动虚拟机。(重启后,别忘了启动hadoop集群)

4) 在hive的bin目录下执行./schematool -dbType mysql -initSchema
