Linux数据库系统实验报告MySQL

一、MYSQL安装1.配置IP（必须配置IP，否则无法使用登陆）[root@localhost~]#vim/etc/sysconfig/network-scripts/ifcfg-eth0BOOTPROTO=noneIPADDR=NETMASK=2.查看是否有安装软件包[root@localhost~]#rpm-qmysqlpackagemysqlisnotinstalled3.把软件包拖进Linux4.解压[root@localhostDesktop]#tar-zxvfmysql-5.1.55.tar.gz-C/usr/src/5.配置[root@localhostDesktop]#cd/usr/src/mysql-5.1.55/[root@localhostmysql-5.1.55]#./configure--prefix=/usr/local/mysql--with-charset=utf8--with-collation=utf8_general_ci--with-extra-charsets=gbk,gb23126.安装[root@localhostmysql-5.1.55]#make&&makeinstall7.创建运行用户[root@localhostmysql-5.1.55]#useradd-M-u49-s/sbin/nologinmysql（此用户名必须为mysql，不能更改）8.建立主配置文件[root@localhostmysql-5.1.55]#cpsupport-files/f/etc/f9.初始化数据库[root@localhostmysql-5.1.55]#cd/usr/local/mysql/bin/[root@localhostbin]#./mysql_install_db--user=mysql使用刚刚创建的mysql用户来初始化数据库使用刚刚创建的mysql用户来初始化数据库 使用刚刚创建的mysql用户来初始化数据库10.更改属组和属主[root@localhostbin]#chown-Rroot:mysql/usr/local/mysql/[root@localhostbin]#chown-Rmysql/usr/local/mysql/var/11.优化执行路径[root@localhostbin]#ln-s/usr/local/mysql/bin/*/usr/local/bin/[root@localhostbin]#ln-s/usr/local/mysql/lib/mysql/*/usr/lib[root@localhostbin]#ln-s/usr/local/mysql/include/mysql/*/usr/include/12.添加系统服务[root@localhostbin]#cd/usr/src/mysql-5.1.55/[root@localhostmysql-5.1.55]#cpsupport-files/mysql.server/etc/rc.d/init.d/mysqld[root@localhostmysql-5.1.55]#chmod+x/etc/rc.d/init.d/mysqld[root@localhostmysql-5.1.55]#chkconfig--addmysqld[root@localhostmysql-5.1.55]#chkconfigmysqldon[root@localhostmysql-5.1.55]#chkconfig--listmysqldmysqld0:关闭1:关闭2:启用3:启用4:启用5:启用6:关闭13.启动服务[root@localhostmysql-5.1.55]#servicemysqldstartStartingMySQL.[确定][root@localhostmysql-5.1.55]#netstat-anpt|grepmysqldtcp00:3306:*LISTEN17643/mysqld（mysqld服务默认占用TCP的3306号端口）14.登陆MYSQLD服务器添加密码：[root@localhostmysql-5.1.55]#mysqladmin-urootpassword'123.com'添加密码添加密码 登陆方法一：[root@localhostmysql-5.1.55]#mysql-uroot-p登陆服务器登陆服务器Enterpassword:输入密码输入密码登陆方法二：[root@localhostmysql-5.1.55]#mysql-uroot-密码紧随其后，没有空格密码紧随其后，没有空格二、使用MYSQL数据库1.查看数据库mysql>showdatabases;查看数据库 查看数据库查看数据库+--------------------+|Database|+--------------------+|information_schema||mysql||test|+--------------------+3rowsinset(0.00sec)2.创建新库mysql>createdatabases2t79;创建名为s2t79的库 创建名为s2t79的库创建名为s2t79的库QueryOK,1rowaffected(0.12sec)mysql>createdatabases2t80;QueryOK,1rowaffected(0.00sec)3.删除库mysql>dropdatabases2t80;删除名为s2t80的库 删除名为s2t80的库删除名为s2t80的库QueryOK,0rowsaffected(0.02sec)4.切换目录mysql>uses2t79切换到库s2t79 切换到库s2t79切换到库s2t79Databasechanged5.创建表，添加字段mysql>createtablehehe(idint(5),namechar(15),gongziint(6),QQint(12));创建名为hehe的表，其中有字段创建名为hehe的表，其中有字段id、name、gongzi、QQ 创建名为hehe的表，其中有字段id、name、gongzi、QQ6.查看表结构mysql>deschehe;查看表hehe的结构 查看表hehe的结构查看表hehe的结构+--------+----------+------+-----+---------+-------+|Field|Type|Null|Key|Default|Extra|+--------+----------+------+-----+---------+-------+|id|int(5)|YES||NULL|||name|char(15)|YES||NULL|||gongzi|int(6)|YES||NULL|||QQ|int(12)|YES||NULL||+--------+----------+------+-----+---------+-------+4rowsinset(0.05sec)7.在表中添加记录mysql>insertintohehe(id,name,QQ)values(1,'zhangsan',1012405802);在表hehe中添加记录在表hehe中添加记录 在表hehe中添加记录8.查询数据记录mysql>select*fromhehe;+------+----------+--------+--------
