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Metastore到MySql
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> <description>Driver class name for a JDBC metastore</description> </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
