一、下载安装包

1，下载hivehttp://mirrors.hust.edu.cn/apache/ 得到apache-hive-1.1.0.tar.gz ，放到该目录下 /home/

2，下载mysql https://dev.mysql.com/downloads/file/?id=471503得到

我的linux版本是6.8,下载时最好选择glib版本，如果下载其它各种组合包，会提示各种依赖关系，比较麻烦

拷贝到该目录下/mysql/

二、安装mysql

1.卸载系统自带的mysql相关安装包，仅卸载mysql开头的包

rpm -qa | grep -i mysql

rpm -ev mysql-community-libs-5.7.19-1.el7.x86_64--nodeps

2.创建用户和组

groupadd mysql

useradd -r -g mysql mysql

3.安装

解压tar -zxvfmysql-5.7.19-linux-glibc2.12-x86_64.tar.gz-C ../usr/local

修改目录[root@hadoop local]# mvmysql-5.7.19-linux-glibc2.12-x86_64/mysql

添加授权[root@hadoop mysql]# chown -Rmysql.mysql /usr/local/mysql

新建data目录[root@hadoop mysql]# mkdir data

4.安装./bin/mysqld --initialize --user=mysql--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

注意最后一行，这也是和之有版本不同的地方，它给了root一个初始密码，此root为mysql的root用户，后面要登录的时候要用到这个密码。#H#,?*Els4G&

4.将mysql/目录下除了data/目录的所有文件，改回root用户所有，mysql用户只需作为mysql/data/目录下所有文件的所有者。

[root@hadoop mysql]# chown -R root .

[root@hadoop mysql]# chown -R mysql data

5.创建tmp文件夹，并授权

[root@hadoop mysql]# mkdir tmp

[root@hadoop mysql]# chown -R mysql:mysql tmp

6.复制并编辑配置文件

[root@hadoop etc]# cp my.cnf.rpmsave my.cnf

[root@hadoop etc]# vi my.cnf

7.添加以下内容

basedir = /usr/local/mysql

datadir = /usr/local/mysql/data

port = 3306

socket = /usr/local/mysql/tmp/mysql.sock

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

8.将mysql.server拷贝到/etc/init.d/mysql

[root@hadoop support-files]# cp mysql.server/etc/init.d/mysql

[root@hadoop init.d]# chmod +x mysql

9.把mysql注册为开机启动的服务
[root@hadoop init.d]# chkconfig --add mysql

[root@hadoop init.d]# chkconfig --list mysql

mysql0:off1:off2:on3:on4:on5:on6:off

10.启动

[root@hadoop init.d]# /etc/init.d/mysql start

Starting MySQL.Logging to'/usr/local/mysql/data/hadoop.err'.

.[OK]

11.修改环境变量

export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:/usr/local/mysql:/usr/local/mysql/bin

[root@hadoop init.d]# source /etc/profile

12.使用root登录时报错

[root@hadoop init.d]# mysql -uroot -p #H#,?*Els4G&

Enter password:

ERROR 2002 (HY000): Can't connect to local MySQLserver through socket '/tmp/mysql.sock' (2)

13.修改 /etc/my.cnf文件，补充mysql和client配置

[mysqld]

basedir = /usr/local/mysql

datadir = /usr/local/mysql/data

port = 3306

socket = /usr/local/mysql/tmp/mysql.sock

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

skip-grant-tables

[mysql]

default-character-set=utf8

socket = /usr/local/mysql/tmp/mysql.sock

[client]

default-character-set=utf8

socket = /usr/local/mysql/tmp/mysql.sock

14.重新登录,并输入新密码

[root@hadoop etc]# mysql -uroot -p #H#,?*Els4G&

Enter password: mysql

15.mysql服务的开启和关闭

#/etc/init.d/mysqlstart或者serivcemysqlstart或者bin/mysqld_safe&

#/etc/init.d/mysqlstop或者servicemysqlstop或者bin/mysqladmin-uroot-p

三、添加hive用户，会提示如下错误

mysql> create user 'hive'@'%' identified by 'hive';

ERROR 1290 (HY000): The MySQL server is running withthe --skip-grant-tables option so it cannot execute this statement

强制写出

mysql> flush privileges;

重新执行

mysql> create user 'hive'@'%' identified by 'hive';

Query OK, 0 rows affected (0.00 sec)

mysql> select host,user from user;

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

| host|user|

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

| %|hive|

| localhost | mysql.session |

| localhost | mysql.sys|

| localhost | root|

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

4 rows in set (0.00 sec)
