2.2安装MySQL

2.2.1安装

顺序安装
rpm -i /opt/software/mysql-community-common-5.7.8-0.3.rc.el7.x86_64.rpm
rpm -i /opt/software/mysql-community-libs-5.7.8-0.3.rc.el7.x86_64.rpm
rpm -i /opt/software/mysql-community-client-5.7.8-0.3.rc.el7.x86_64.rpm

rpm -i /opt/software/mysql-community-server-5.7.8-0.3.rc.el7.x86_64.rpm

ps:

重新安装
systemctl stop mysqld
systemctl disable mysqld.pid
rm -rf /etc/my.cnf
rm -rf /var/log/mysqld.log 
rm -rf /var/run/mysqld
rpm -e mysql-community-common-5.7.8-0.3.rc.el7.x86_64 mysql-community-client-5.7.8-0.3.rc.el7.x86_64  mysql-community-server-5.7.8-0.3.rc.el7.x86_64 mysql-community-libs-5.7.8-0.3.rc.el7.x86_64  mysql-community-devel-5.7.8-0.3.rc.el7.x86_64
rm -rf /var/lib/mysql
rm -rf /var/lib/mysql/mysql
rm -rf /usr/share/mysql

####2.2.2配置 echo 'default-storage-engine=innodb' >> /etc/my.cnf echo 'innodb_file_per_table' >> /etc/my.cnf echo 'collation-server=utf8_general_ci' >> /etc/my.cnf echo "init-connect='SET NAMES utf8'" >> /etc/my.cnf echo 'character-set-server=utf8' >> /etc/my.cnf

ps:

默认存储引擎：innodb
为每张表设置存储引擎为innodb
排序规则为：utf8_general_ci
为每一个新连接设置编码格式：utf8
服务器端采用编码格式：utf8

####2.2.3初始化

systemctl start mysqld
systemctl enable mysqld
grep "password" /var/log/mysqld.log
mysql_secure_installation

New password: Jcg7336$Re-enter new password: Jcg7336$Change the password for root ? ((Press y|Y for Yes, any other key for No) : nRemove anonymous users? (Press y|Y for Yes, any other key for No) : yDisallow root login remotely? (Press y|Y for Yes, any other key for No) : nRemove test database and access to it?

二、安装Hive

1.下载

官网：https://archive.apache.org/dist/hive/
下载地址1：https://mirrors.huaweicloud.com/apache/hive/

ps:

阿里云镜像和中科大镜像版本不全

2.解压

tar -zxf /opt/software/apache-hive-3.1.2-bin.tar.gz -C /opt/module/
mv /opt/module/apache-hive-3.1.2-bin/ /opt/module/hive

3配置

3.1将二进制路径添加进命令行

cp /opt/module/hadoop/share/hadoop/common/lib/guava-27.0-jre.jar /opt/module/hive/lib/;rm -rf /opt/module/hive/lib/guava-19.0.jar
echo "export HIVE_HOME=/opt/module/hive" >> /etc/profile
echo 'export PATH=$PATH:$HIVE_HOME/bin' >> /etc/profile
source /etc/profile

3.2配置hive-site.xml

3.2.1服务端

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://master:3306/metastore?createDatabaseIfNotExist=true&amp;useSSL=false</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>

<value>root</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>

</property>
<property>
<name>hive.metastore.local</name>
<value>false</value>
</property>
<property>
<name>hive.metastore.uris</name>

</property>
</configuration>

3.2.1客户端

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hive.metastore.local</name>
<value>false</value>
</property>
</configuration>

</property>
</configuration>

3.3jar包

cp /opt/software/mysql-connector-java-5.1.47.jar /opt/module/hive/lib/
cp /opt/module/hadoop/share/hadoop/common/lib/guava-27.0-jre.jar /opt/module/hive/lib/;rm -rf /opt/module/hive/lib/guava-19.0.jar

（方式一）
nohup hive --service metastore &
（方式二）
nohup hive --service hiveserver2 &

5.2启动客户端

（方式一）
hive
（方式二）
booline -u jdbc:hive2://master:10000 -n root -p 123456
