一、基础环境

Hive 组件需要基于之前已部署完毕的 Hadoop 全分布系统，在 master 节点上实现 Hive 组件安装。

1、Hadoop-全分布式配置（全部配置）
2、Hadoop-集群运行（部分配置）

# 查看之前部署的环境
[root@master ~]# su - hadoop

[hadoop@master ~]$ jps
47967 Jps

[hadoop@master hadoop]$ start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [master]
master: starting namenode, logging to /usr/local/src/hadoop/logs/hadoop-hadoop-namenode-master.example.com.out
192.168.100.30: starting datanode, logging to /usr/local/src/hadoop/logs/hadoop-hadoop-datanode-slave2.example.com.out
192.168.100.20: starting datanode, logging to /usr/local/src/hadoop/logs/hadoop-hadoop-datanode-slave1.example.com.out
Starting secondary namenodes [0.0.0.0]
0.0.0.0: starting secondarynamenode, logging to /usr/local/src/hadoop/logs/hadoop-hadoop-secondarynamenode-master.example.com.out
starting yarn daemons
starting resourcemanager, logging to /usr/local/src/hadoop/logs/yarn-hadoop-resourcemanager-master.example.com.out
192.168.100.30: starting nodemanager, logging to /usr/local/src/hadoop/logs/yarn-hadoop-nodemanager-slave2.example.com.out
192.168.100.20: starting nodemanager, logging to /usr/local/src/hadoop/logs/yarn-hadoop-nodemanager-slave1.example.com.out

[hadoop@master hadoop]$ jps
44678 NameNode
45030 ResourceManager
45289 Jps
44874 SecondaryNameNode

[hadoop@master hadoop]$ exit
logout

要确保 Hadoop 系统能够正常运行

二、安装MySQL

注意：使用 root 用户登录

1、传输需要的包到/opt目录下

[root@master ~]# cd /opt/software/
[root@master software]# ls
apache-hive-2.0.0-bin.tar.gz  jdk-8u152-linux-x64.tar.gz  mysql-connector-java-5.1.46.jar
hadoop-2.7.1.tar.gz           mysql-5.7.18.zip

2、卸载自带的MariaDB

[root@master software]# rpm -qa | grep mariadb
mariadb-libs-5.5.52-1.el7.x86_64
[root@master software]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64

3、解压mysql-5.7.18.zip

[root@master software]# ls
apache-hive-2.0.0-bin.tar.gz  jdk-8u152-linux-x64.tar.gz  mysql-connector-java-5.1.46.jar
hadoop-2.7.1.tar.gz           mysql-5.7.18.zip

[root@master software]# unzip mysql-5.7.18.zip 
Archive:  mysql-5.7.18.zip
   creating: mysql-5.7.18/
  inflating: mysql-5.7.18/mysql-community-client-5.7.18-1.el7.x86_64.rpm  
  inflating: mysql-5.7.18/mysql-community-common-5.7.18-1.el7.x86_64.rpm  
  inflating: mysql-5.7.18/mysql-community-devel-5.7.18-1.el7.x86_64.rpm  
  inflating: mysql-5.7.18/mysql-community-libs-5.7.18-1.el7.x86_64.rpm  
  inflating: mysql-5.7.18/mysql-community-server-5.7.18-1.el7.x86_64.rpm

4、依次安装MySQL数据库

[root@master software]# cd mysql-5.7.18/
[root@master mysql-5.7.18]# ls
mysql-community-client-5.7.18-1.el7.x86_64.rpm  mysql-community-libs-5.7.18-1.el7.x86_64.rpm
mysql-community-common-5.7.18-1.el7.x86_64.rpm  mysql-community-server-5.7.18-1.el7.x86_64.rpm
mysql-community-devel-5.7.18-1.el7.x86_64.rpm

[root@master mysql-5.7.18]# rpm -ivh mysql-community-common-5.7.18-1.el7.x86_64.rpm
warning: mysql-community-common-5.7.18-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

Updating / installing...
   1:mysql-community-server-5.7.18-1.e################################# [100%]

5、修改配置

添加配置信息到/etc/my.cnf 文件 symbolic-links=0 的下方

[root@master mysql-5.7.18]# vi /etc/my.cnf

default-storage-engine=innodb
innodb_file_per_table
collation-server=utf8_general_ci
init-connect='SET NAMES utf8'
character-set-server=utf8

6、启动MySQL

[root@master mysql-5.7.18]# systemctl start mysqld
[root@master mysql-5.7.18]# systemctl status mysqld
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
   Active: active (running) since Sat 2022-04-09 10:12:27 CST; 44s ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
  Process: 45577 ExecStart=/usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid $MYSQLD_OPTS (code=exited, status=0/SUCCESS)
  Process: 45499 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS)

   CGroup: /system.slice/mysqld.service
           └─45580 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid

Apr 09 10:12:17 master.example.com systemd[1]: Starting MySQL Server...
Apr 09 10:12:27 master.example.com systemd[1]: Started MySQL Server.

7、查询MySQL默认密码

[root@master ~]# cat /var/log/mysqld.log | grep password
2022-04-09T02:12:24.671882Z 1 [Note] A temporary password is generated for root@localhost: /RrHz+J-t1fj

默认密码为/RrHz+J-t1fj

8、初始化MySQL

是否更改 root 用户密码n
是否使用设定的密码继续y
是否删除匿名用户y
是否拒绝 root 用户远程登录n
是否删除测试数据库y
是否重新加载授权表y

[root@master ~]# mysql_secure_installation

Securing the MySQL server deployment.

Enter password for user root: 

The existing password for the user account root has expired. Please set a new password.

New password: 

Re-enter new password: 
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration
of the plugin.
Using existing password for root.

Estimated strength of the password: 100 
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n

Estimated strength of the password: 100 
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : n

 ... skipping.

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n

 ... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : n

 ... skipping.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : n

 ... skipping.
All done!

9、进入数据库，添加权限

添加 root 用户从本地和远程访问 MySQL 数据库表单的授权

[root@master ~]# mysql -uroot -p
Enter password:

| root | localhost |
+------+-----------+
2 rows in set (0.00 sec)

mysql> exit;
Bye
[root@master ~]#

二、配置Hive组件

1、设置Hive环境变量

# 解压hive文件
[root@master ~]# tar -zxf /opt/software/apache-hive-2.0.0-bin.tar.gz 
[root@master ~]# mv apache-hive-2.0.0-bin/ /usr/local/src/hive

# 修改用户和用户组为 hadoop
[root@master ~]# chown -R hadoop:hadoop /usr/local/src/hive

# 添加配置信息
[root@master ~]# vi /etc/profile
# set hive environment
export HIVE_HOME=/usr/local/src/hive
export PATH=$PATH:$HIVE_HOME/bin

[root@master ~]# source /etc/profile

2、修改Hive组件配置文件

[root@master ~]# su - hadoop

[hadoop@master ~]$ cp /usr/local/src/hive/conf/hive-default.xml.template /usr/local/src/hive/conf/hive-site.xml

[hadoop@master ~]$ vi /usr/local/src/hive/conf/hive-site.xml

    <value>root</value>
    <description>Username to use against metastore database</description>
    
# 配置目录信息（共4处）
    <name>hive.querylog.location</name>
    <value>/usr/local/src/hive/tmp</value>
    <description>Location of Hive run time structured log file</description>

    <name>hive.server2.logging.operation.log.location</name>
    <value>/usr/local/src/hive/tmp/operation_logs</value>

[hadoop@master ~]$ mkdir -p /usr/local/src/hive/tmp{resources,operation_logs}

3、重启all.sh

[hadoop@master ~]$ cp /opt/software/mysql-connector-java-5.1.46.jar /usr/local/src/hive/lib/

[hadoop@master ~]$ stop-all.sh
This script is Deprecated. Instead use stop-dfs.sh and stop-yarn.sh

192.168.100.20: starting nodemanager, logging to /usr/local/src/hadoop/logs/yarn-hadoop-nodemanager-slave1.example.com.out

4、初始化数据库

[hadoop@master ~]$ schematool -initSchema -dbType mysql
