大家好，今天是我在51CTO上的第一篇博文，以此来督促我自个养成一个好的学习习惯，也希望给大家有所帮助。
ok，言归正传，今天我介绍的是在CentOS6环境下安装MySQL数据库，我所用到的是CentOS6镜像文件中所带的mysql包。
1、配置本地yum源。
[[email protected] ~]# cd /etc/yum.repos.d/
[[email protected] yum.repos.d]# ls
CentOS-Base.repo.bak CentOS-Debuginfo.repo.bak CentOS-fasttrack.repo.bak CentOS-Media.repo CentOS-Vault.repo.bak
修改如下：
[[email protected] yum.repos.d]# vim CentOS-Media.repo
baseurl=file:///mnt */mnt为挂载点*
enabled=1 *开启状态*
2、安装mysql。
[[email protected] ~]# yum list | grep mysql *查询与mysql有关的包*
[[email protected] ~]# yum install -y mysql-server.x86_64 mysql.x86_64 mysql-devel.x86_64 *安装mysql包和开发所用到的包*
[[email protected] ~]# service mysqld start *初始化mysql数据库*
[[email protected] ~]# service mysqld restart *重启mysql服务*
[[email protected] ~]# mysqladmin -u root password ‘123456‘ *配置管理mysql的用户的密码*
[[email protected] ~]# mysql -u root -p
Enter password: *登录mysql，输入管理密码*
出现如下，表示登录成功：
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 12

mysql>
相关命令： show databases； *查看目前有的数据库*
create database ming； *创建名字为ming的数据库*
3、mysql的配置文件。
[[email protected] ~]# cd /etc/
[[email protected] etc]# ls my.cnf
my.cnf
4、mysql数据库的库所在位置。
[[email protected] ~]# cd /var/lib/mysql/
[[email protected] mysql]# ls
ibdata1 ib_logfile0 ib_logfile1 ming mingming mysql mysql.sock test
5、mysql数据库的日志文件所在位置。
[[email protected] ~]# cd /var/log/
[[email protected] log]# ls
anaconda.ifcfg.log btmp dmesg maillog-20150802 prelink spooler-20150714

[[email protected] log]# cat mysqld.log
Version: ‘5.1.73‘ socket: ‘/var/lib/mysql/mysql.sock‘ port: 3306 Source distribution
*mysql服务是TCP，端口号为3306*
6、监听mysql服务。
[[email protected] ~]# netstat -tlun
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
