Linux下如何使用yum的方式安装mysql

1. 先检查系统是否装有MySQL[root@localhost ~]#yum list installed mysql*[root@localhost ~]#rpm –qa|grep mysql* 2. 查看有没有安装包 [root@localhost ~]#yum list mysql* 3. 安装mysql客户端 [root@localhost ~]yum install mysql 4. 安装mysql服务端 [root@localhost ~]#yum install mysql-server[root@localhost ~]#yum install mysql-devel 5. 在/etc/my.cnf 文件中加入默认字符集 [root@localhost ~]#vim /etc/my.cnf6. 启动或者关闭mysql服务 [root@localhost ~]#service mysqld start –启动mysql 或者 /etc/init.d/mysqld start (关闭mysql #service mysql stop)

7. 设置开机启动mysql服务

[root@localhost ~]# chkconfig –add mysqld

8. 创建root用户 密码为123456

mysqladmin –u root password 123456

[root@localhost ~]# mysqladmin -u root password 123456

9. 连接mysql

[root@localhost ~]# mysql -u root -p –输入密码123456

10. 设置远程访问权限

mysql> use mysql mysql> GRANT ALL PRIVILEGES ON *.* TO ‘admin’@’%’IDENTIFIED BY ‘admin’ WITH GRANT OPTION; –第一个admin为用户名，第二个admin为密码，%表示所有的电脑都可以链接 mysql> flush privileges; –设置立即生效mysql> SELECT DISTINCT CONCAT(User:,user,@,host,;) AS query FROM mysql.user; mysql> exit; –退出mysql服务 [root@localhost ~]# vi /etc/my.cnf[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql default-character-set=utf8# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0#设备地址bind-address=0.0.0.0 #设置设备地址[mysqld_safe]log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [root@localhost ~]# service mysqld start –重启mysql服务[root@localhost ~]# mysql -u root -p –连接mysql输入密码mysql> show global variables like port; –查看端口号 +—————+——-+ | Variable_name | Value | +—————+——-+ | port | 3306 | +—————+——-+ 1 row in set (0.00 sec)

11.使用navcat连接mysql

大功告成。。。
