安装mysql,mysql-server,mysql-devel.

[root@microlmj~]# yum -y install mysql

[root@microlmj~]# yum -y install mysql-server

[root@microlmj~]# yum -y install mysql-devel

---Complete!
设置字符编码

[root@microlmj~]# vi /etc/my.cnf [mysqld]datadir=/var/lib/mysqlsocket=/var/lib/mysql/mysql.sockuser=mysql# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.pid#new adddefault-character-set=utf8

启动服务

[root@microlmj init.d]# /etc/rc.d/init.d/mysqld start                                                           [  OK  ]Starting mysqld:                                           [  OK  ]

刚安装的mysql root 用户 是没有密码的 登录 自己设置密码

[root@microlmj init.d]# mysql -u rootWelcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 2Server version: 5.1.73 Source distributionCopyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql> 

看一下用户列表

mysql> select user ,host, password from mysql.user;+------+-----------------------+----------+| user | host                  | password |+------+-----------------------+----------+| root | localhost             |          || root | ay14031710421034561bz |          || root | 127.0.0.1             |          ||      | localhost             |          ||      | ay14031710421034561bz |          |+------+-----------------------+----------+5 rows in set (0.00 sec)

密码栏都是空的
给root@localhost设置一个密码

mysql> set password for root@localhost=password('yourpassword');Query OK, 0 rows affected (0.00 sec)

再看一下用户表

mysql> select user ,host, password from mysql.user;+------+-----------------------+-------------------------------------------+| user | host                  | password                                  |+------+-----------------------+-------------------------------------------+| root | localhost             | *7E7C3D7567802A1EC617020149BB4B81E551B5EB || root | ay14031710421034561bz |                                           || root | 127.0.0.1             |                                           ||      | localhost             |                                           ||      | ay14031710421034561bz |                                           |+------+-----------------------+-------------------------------------------+5 rows in set (0.00 sec)

退出再重新登录

mysql> exitBye[root@microlmj init.d]# mysql -u root ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

需要密码了 -.-
输入密码登录 0>.<0

[root@microlmj init.d]# mysql -u root -pEnter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 7Server version: 5.1.73 Source distribution...Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql> 

本地的访问就没问题了 perhaps  -.-
但是俺想远程访问
新建个用户microlmj  (*用root账户登陆先)

mysql> insert into mysql.user(Host,User,Password) values("%","microlmj",password("microlmj"));

Host字段是 % 允许所有地址访问
刷新系统权限-.-

mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)

[root@microlmj init.d]# mysql -u microlmj -pEnter password: Welcome to the MySQL monitor.  Commands end with ; or \g....Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql>

用新建的用户登录 创建一个表试试

mysql> use test;Database changedmysql> show tables;Empty set (0.00 sec)mysql> create table user (id int primary key, name varchar(10));Query OK, 0 rows affected (0.01 sec)mysql> desc user;+-------+-------------+------+-----+---------+-------+| Field | Type        | Null | Key | Default | Extra |+-------+-------------+------+-----+---------+-------+| id    | int(11)     | NO   | PRI | NULL    |       || name  | varchar(10) | YES  |     | NULL    |       |+-------+-------------+------+-----+---------+-------+2 rows in set (0.00 sec)

好吧，用navicat测试一下远程访问行不行 -.-

连接成功 -.-
Complete!
