一、下載安裝包
1,下載hive http://mirrors.hust.edu.cn/apache/ 得到apache-hive-1.1.0.tar.gz ,放到該目錄下 /home/
2,下載mysql https://dev.mysql.com/downloads/file/?id=471503得到
我的linux版本是6.8,下載時最好選擇glib版本,如果下載其它各種組合包,會提示各種依賴關系,比較麻煩
拷貝到該目錄下/mysql/
二、安裝mysql
1.卸載系統自帶的mysql相關安裝包,僅卸載 mysql 開頭的包
rpm -qa | grep -i mysql
rpm -ev mysql-community-libs-5.7.19-1.el7.x86_64 --nodeps
2.創建用戶和組
groupadd mysql
useradd -r -g mysql mysql
3.安裝
解壓tar -zxvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz -C ../usr/local
修改目錄[root@hadoop local]# mv mysql-5.7.19-linux-glibc2.12-x86_64/ mysql
添加授權[root@hadoop mysql]# chown -R mysql.mysql /usr/local/mysql
新建data目錄[root@hadoop mysql]# mkdir data
4.安裝./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
注意最后一行,這也是和之有版本不同的地方,它給了root一個初始密碼,此root為mysql的root用戶,后面要登錄的時候要用到這個密碼。#H#,?*Els4G&
4.將mysql/目錄下除了data/目錄的所有文件,改回root用戶所有,mysql用戶只需作為mysql/data/目錄下所有文件的所有者。
[root@hadoop mysql]# chown -R root .
[root@hadoop mysql]# chown -R mysql data
5.創建tmp文件夾,并授權
[root@hadoop mysql]# mkdir tmp
[root@hadoop mysql]# chown -R mysql:mysql tmp
6.復制并編輯配置文件
[root@hadoop etc]# cp my.cnf.rpmsave my.cnf
[root@hadoop etc]# vi my.cnf
7.添加以下內容
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.將mysql.server拷貝到/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注冊為開機啟動的服務
[root@hadoop init.d]# chkconfig --add mysql
[root@hadoop init.d]# chkconfig --list mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
10.啟動
[root@hadoop init.d]# /etc/init.d/mysql start
Starting MySQL.Logging to '/usr/local/mysql/data/hadoop.err'.
. [ OK ]
11.修改環境變量
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登錄時報錯
[root@hadoop init.d]# mysql -uroot -p #H#,?*Els4G&
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
13.修改 /etc/my.cnf文件,補充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.重新登錄,并輸入新密碼
[root@hadoop etc]# mysql -uroot -p #H#,?*Els4G&
Enter password: mysql

15.mysql服務的開啟和關閉
#/etc/init.d/mysql start 或者 serivce mysql start 或者 bin/mysqld_safe&
#/etc/init.d/mysql stop 或者 service mysql stop 或者 bin/mysqladmin -uroot -p
三、添加hive用戶,會提示如下錯誤
mysql> create user 'hive'@'%' identified by 'hive';
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
強制寫出
mysql> flush privileges;
重新執行
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)
