Linux操作系统下MySQL的查看

Jun 07, 2016 pm 04:51 PM

1、安装查看Linux操作系统是否已经安装了MYSQLrpm -qa mysqlmysql-4.1.7-4.RHEL4.1点开add/remove programe里面的mysql的detail勾

1、安装
查看Linux操作系统是否已经安装了MYSQL
rpm -qa mysql

mysql-4.1.7-4.RHEL4.1

点开add/remove programe里面的mysql的detail
勾上mysql-server

2、启动
来检测mysql是否已经启动
service mysqld status

我们可以用三种方法来启动Mysql:
方法一:使用service命令来
启动Mysql
service mysqld start
停止mysql
service mysqld stop
方法二:使用mysqld脚本来启动Mysql:
/etc/init.d/mysql start
方法三:使用safe_mysqld实用程序启动Mysql服务,此方法可以使用相关参数
safe_mysqld& //使用&表示将safe_mysqld放在后台执行。

3、登陆
修改密码
mysqladmin -u root password
mysqladmin -u root password 'kaishi'

这里的“密码”为我们欲新设的密码。系统会提示我们输入旧密码(若是mysql刚安装,则默认密码为空)

本机可以登陆了。但是其他机器的客户端登陆报错。
ERROR 1130 (00000): Host 'xxx.xxx.xxx.xxx' is not allowed to connect to this MySQ
L server

首先查看了iptables的设置,添加开放了3306端口
iptables -A INPUT -p tcp -m tcp --sport 3306 -j ACCEPT
iptables -A OUTPUT -p tcp -m tcp --dport 3306 -j ACCEPT

service iptables save
service iptables restart

还是其他机器不能访问,估计是MYSQL权限问题。

在本机登陆
mysql -h localhost -u root -pkaishi
show databases;
use mysql;
select Host, User, Password from user;
+-----------------------+------+-------------------------------------------+
| Host | User | Password |
+-----------------------+------+-------------------------------------------+
| localhost | root | *18F54215F48E644FC4E0F05EC2D39F88D7244B1A |
| localhost.localdomain | root | |
| localhost.localdomain | | |
| localhost | | |
+-----------------------+------+-------------------------------------------+
可以看到如上结果,,只有localhost才设置了访问的权限
