centos7安装hive

安装前准备

1.安装Mysql

tar -xvf MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle.tar

MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-shared-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-devel-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-client-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-shared-compat-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-embedded-5.6.26-1.linux_glibc2.5.x86_64.rpm
MySQL-test-5.6.26-1.linux_glibc2.5.x86_64.rpm

安装服务端：

rpm -ivh MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm

警告：MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1f5: NOKEY
错误：依赖检测失败：
    /usr/bin/perl 被 MySQL-server-5.6.26-1.linux_glibc2.5.x86_64 需要

缺少依赖perl 

yum list |grep perl

yum install -y perl.x86_64

mariadb-libs-1:5.5.56-2.el7.x86_64包冲突

rpm -e mariadb-libs-1:5.5.56-2.el7.x86_64 --nodeps

报错：

FATAL ERROR: please install the following Perl modules before executing /usr/bin/mysql_install_db:

解决方法：yum -y install autoconf

/usr/bin/mysql_install_db --user=mysql

安装client

rpm -ivh MySQL-client-5.6.26-1.linux_glibc2.5.x86_64.rp

mysql> use mysql
mysql> update user set password=PASSWORD('123456') where User='root';
#给所有主机授权
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

安装成功！

2.安装hive-1.2.1

tar -zvxf apache-hive-1.2.1-bin.tar.gz

在conf目录下

新增hive-site.xml

<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost: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>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>123456</value>
<description>password to use against metastore database</description>
</property>
</configuration>

注意：HADOOP_HOME环境变量需要配置

启动：bin/hive

报错：

原因：没有将MySQL中的mysql库下的user表的权限修改，后来修改后没有对权限进行刷新造成权限没有生效。

解决方法：

再次修改root权限的密码；

mysql> SET PASSWORD=PASSWORD('新的密码');

修改完成后刷新权限；

mysql> flush privileges;

这样操作完成后退出mysql，然后重新执行 bin/hive 命令即可。
