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.cnf

\6. 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
