数据可视化第7篇：linux安装davinci之mysql

1、前期准备

(1)查看MySQL是否安装

rpm -qa|grep mysql

mysql-libs-5.1.73-7.el6.x86_64

(2)如果安装了MySQL，就先卸载

rpm -e --nodeps mysql-libs-5.1.73-7.el6.x86_64

(3)解压mysql-libs.zip文件到当前目录

cd /tmp

unzip mysql-libs.zip

cd mysql-libs

2、安装MySQL服务器

(1)安装MySQL服务端

rpm -ivh MySQL-server-5.6.24-1.el6.x86_64.rpm

(2)查看产生的随机密码

cat /root/.mysql_secret

CYgyeizHQxXoPR2N

(3)查看MySQL状态

service mysql status

(4)启动MySQL

service mysql start

3、安装MySQL客户端

(1)安装MySQL客户端

rpm -ivh MySQL-client-5.6.24-1.el6.x86_64.rpm

(2)登录MySQL 

mysql -u root -pCYgyeizHQxXoPR2N

(3)修改密码

mysql>SET PASSWORD=PASSWORD('000000');

(4)退出MySQL

mysql>exit

4、MySQL主机配置(root在任何主机上都能登录MySQL)

(1)登录MySQL

mysql -uroot -p000000

(2)指定操作的数据库

mysql>use mysql;

(3)修改user表，把Host表内容修改为%

mysql>update user set host='%' where host='localhost';

(4)删除root用户的其他host

mysql>

delete from user where Host='hadoop102';

delete from user where Host='127.0.0.1';

delete from user where Host='::1';

(5)刷新权限

flush privileges;

5、修改字符集为utf8

(1)查看当前字符集默认设置

mysql> show variables like '%char%';

(2)修改配置文件(修改字符集为utf-8、忽略表名大小写、tab补全命令)

vi /etc/my.cnf

(4)重启mysql服务

[root@hadoop102 ~]# service mysql stop

[root@hadoop102 ~]# service mysql start

(3)查看当前字符集设置

[root@hadoop102 ~]# mysql -u root -p000000

mysql> show variables like '%char%';

6、创建davinci配置信息保存的数据库

(1)创建davinci用的数据库

create database davinci3;

(2)查看数据库默认编码是否是utf8

show create database davinci3;

(3)退出

mysql>quit;
