mysql怎么样进行安装

这篇文章主要为大家展示了“mysql怎么样进行安装”，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下“mysql怎么样进行安装”这篇文章吧。

一、-安装包

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

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

 我的linux版本是6.8,-时最好选择glib版本，如果-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 -zxvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz -C ../usr/local

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

添加授权[root@hadoop mysql]# chown -R mysql.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-f.rpmsave my-f

[root@hadoop etc]# vi my-f

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

mysql           0:off  1:off  2:on  3:on  4:on  5:on  6: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): Cant connect to local MySQL server through socket /tmp/mysql.sock (2)

13.修改 /etc/my-f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/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用户，会提示如下错误

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

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)
