Mysql数据库系统部署使用和远程访问Mysql数据库_mysql

推荐步骤：

➢在 Centos01 上安装 Mysql 数据库服务，生成服务器其配置文件，添加系统服务优化命令初始化 mysql，设置访问密码登录 mysql 数据库

➢ 在 Centos01 的 mysql 服务器上创建数据库，数据库创建表修改表中数据

➢ 授权用户访问 Mysql 数据库增强数据库安全和数据库远程管理

实验步骤：

一部署Mysql数据库系统

1，配置yum仓库安装依赖软件

1）挂载系统盘

2）挂载系统光盘到/mnt目录

[root@centos01 ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@centos01 ~]# ls /mnt/
CentOS_BuildTag  GPL       LiveOS   RPM-GPG-KEY-CentOS-7EFI              images   
Packages RPM-GPG-KEY-CentOS-Testing-7    EULA       isolinux  repodata  TRANS.TBL

3）删除系统自带yum仓库配置本地yum仓库

[root@centos01]# rm -rf /etc/yum.repos.d/CentOS-*
[root@centos01]# ls /etc/yum.repos.d/
local.repo
[root@centos01]# vim /etc/yum.repos.d/local.repo 
[local]
name=centos
baseurl=file:///mnt
enabled=1
gpgcheck=0

4）安装依赖程序

[root@centos01~]# yum -y install ncurses-devel cmake

2，切换mysql程序光盘解压源代码程序

1）卸载系统光盘挂载点

[root@centos01 ~]# umount /mnt/
[root@centos01 ~]# ls /mnt/

2）切换mysql程序光盘

3）挂载程序光盘

[root@centos01 ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@centos01 ~]# ls -ld /mnt/mysql-5.5.22.tar.gz 
-r-xr-xr-x 1 root root 24475686 6月  26 2014   /mnt/mysql-5.5.22.tar.gz

4）解压代码程序到/usr/src目录

[root@centos01 ~]# tar zxvf /mnt/mysql-5.5.22.tar.gz -C /usr/src/ 
[root@centos01 ~]# ls /usr/src/
debug kernels  mysql-5.5.22

3，配置安装mysql

1）配置mysql

[root@centos01 ~]# cd /usr/src/mysql-5.5.22/
[root@centos01 mysql-5.5.22]# cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql\ 
-DSYSCONFDIR=/etc/ \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \ 
-DWITH_EXTRA_CHARSETS=all

2）编译安装mysql

[root@centos01 mysql-5.5.22]# make && make install
[root@centos01 mysql-5.5.22]# ls -ld /usr/local/mysql/
drwxr-xr-x 13 root root 213 3月  12 02:09 /usr/local/mysql/

3）创建管理mysql组和用户

[root@centos01 mysql-5.5.22]# groupadd mysql
[root@centos01 mysql-5.5.22]# useradd -M -s /sbin/nologin mysql -g mysql

4）修改目录的使用者

[root@centos01 mysql-5.5.22]# chown -R mysql:mysql /usr/local/mysql/
[root@centos01 mysql-5.5.22]# ls -ld /usr/local/mysql/
drwxr-xr-x 13 mysql mysql 213 3月  12 02:09 /usr/local/mysql/

5）生成mysql主配置文件覆盖原有文件

[root@centos01 mysql-5.5.22]# cp support-files/my-medium.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y

6）生产服务器添加执行权限添加系统服务设置开机自动启动

[root@centos01 mysql-5.5.22]# cp support-files/mysql.server /etc/init.d/mysqld
[root@centos01 mysql-5.5.22]# chmod +x /etc/init.d/mysqld
[root@centos01 mysql-5.5.22]# chkconfig --add mysqld
[root@centos01 mysql-5.5.22]# chkconfig --level 35 mysqld on

7）优化mysql执行命令

[root@centos01 mysql-5.5.22]#  echo "PATH=$PATH:/usr/local/mysql/bin/" >> /etc/profile
[root@centos01 mysql-5.5.22]# source /etc/profile

8）初始mysql

[root@centos01 ~]#  /usr/local/mysql/scripts/mysql_install_db --user=mysql 
--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

4，控制mysql服务mysql数据库设置密码

1）启动mysql服务

[root@centos01]# systemctl start mysqld
[root@centos01]# netstat -anptu | grep mysqld
tcp        0     0 0.0.0.0:3306           0.0.0.0:*              
LISTEN      51176/mysqld

2）空密码登录mysql数据库和退出

[root@centos01]# mysql -urot -p
Enter password:
mysql>exit
Bye

3）设置mysql密码使用账户管理登录

[root@centos01]# mysqladmin -uroot password
Newpassword: 
Confirm new password:

二，mysql数据库标和记录管理

1，数据库管理

1）登录mysql创建数据库名字YY123

[root@centos01 ~]# mysql -uroot -ppwd@123
mysql> create database HB3060;
Query OK, 1 row affected (0.00 sec)

2）查看创建的数据库

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| HB3060             |
| mysql              |
| performance_schema |
| test               |
+--------------------+
5 rows in set (0.00 sec)

3）切换到创建HB3060数据库和mysql数据库

mysql> use HB3060;
Database changed
mysql> use mysql;
Database changed

4）删除HB3060数据库查看创建的数据库

mysql> drop database HB3060;
Query OK, 0 rows affected (0.00 sec)
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |

+--------------------+
4 rows in set (0.00 sec)

2，数据库的管理

1）创建accp数据库，在accp数据库创建student表格设置表格4列数据库三类为字符串1列数据库为整数类

mysql> create database accp;
Query OK, 1 row affected (0.00 sec)
mysql> create table accp.student (姓名 char(5),年龄 int, 身份证号码 char(18),primary key(身份证号码));
Query OK, 0 rows affected (0.00 sec)

2）查看创建的表格结构

mysql> desc accp.student;
+-----------------+----------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------------+----------+------+-----+---------+-------+
| 姓名 | char(4)  | YES |    | NULL |      |                |
| 年龄 | int(11)  | YES |    | NULL |      |                |

| 身份证号码       | char(18) | NO   | PRI  |   							|
+-----------------+----------+------+-----+---------+-------+
4 rows in set (0.00 sec)

3）切换到accp数据库，查看创建的表

mysql> use accp;
Database changed
mysql> show tables; 
+------------------+
| Tables_in_accp   |
+------------------+
| student          |
+------------------+
2 rows in set (0.00 sec)

4）删除创建的 student 表

mysql> drop table student;
Query OK, 0 rows affected (0.01 sec)

3，表中记录管理

1） student表中插入连续列数据

mysql>  insert into accp.student values (‘uu’',18,'13161295986','111345679124689018');
Query OK, 1 row affected (0.01 sec)

2） student表中插入不连续列数据

mysql> insert into accp.student (姓名,身份证号码) values ('YY','110678654108765416');
Query OK, 1 row affected (0.01 sec)

3）查看student表中所有数据

mysql> select * from accp.student;
+-----------+--------+-------------+--------------------+
| 姓名 | 年龄 | 电话             | 身份证号码              |
+-------------+--------+-------------+------------------+
| UU  | NULL | NULL            | 110678654108765416     |

+-----------+--------+-------------+--------------------+
row in set (0.00 sec)

三，授权用户管理数据库和远程管理数据库修改数据库密码

1，授权和撤销授权的配置

1）授权用户bob对accp数据库下的所有表拥有完全控制权限通过远程计算机192.168.100.20访问

mysql> grant all on accp.* to 'bob'@'192.168.100.20' identified by 'pwd@123';
Query OK, 0 rows affected (0.00 sec)

2）查看授权的bob用户权限

mysql> show grants for bob@192.168.100.20;
+--------------------------------------------------------------------------------------
---------------------------+
| Grants for bob@192.168.100.20 
|
+--------------------------------------------------------------------------------------
---------------------------+
| GRANT USAGE ON *.* TO 'bob'@'192.168.100.20' IDENTIFIED BY PASSWORD 
'*760F60073FD235571A5260444301DB22136ED604' |
| GRANT ALL PRIVILEGES ON `accp`.* TO 'bob'@'192.168.100.20' 
|
+--------------------------------------------------------------------------------------
---------------------------+
2 rows in set (0.00 sec)

3）撤销权限

mysql> revoke all on accp.* from 'bob'@'192.168.100.20';
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for bob@192.168.100.20;
+--------------------------------------------------------------------------------------
---------------------------+
| Grants for bob@192.168.100.20 
|
+--------------------------------------------------------------------------------------
---------------------------+
| GRANT USAGE ON *.* TO 'bob'@'192.168.100.20' IDENTIFIED BY PASSWORD 
'*760F60073FD235571A5260444301DB22136ED604' |
+--------------------------------------------------------------------------------------
---------------------------+
1 row in set (0.00 sec)
mysql>

2，权限远程Linux的客户端mysql数据库
