Mysql linux 安装

引用

Redhat 5 下安装Mysql

1.下载Server和client
Server：

wget http://mysql.easynet.be/Downloads/MySQL-5.5/MySQL-server-5.5.25-1.rhel5.x86_64.rpm

Client：

 wget http://mysql.easynet.be/Downloads/MySQL-5.5/MySQL-client-5.5.25-1.rhel5.x86_64.rpm

2.安装server和client

安装Server

[root@inc-platform-dev-153-135 mysql]#  rpm -ivh MySQL-server-4.0.16-0.i386.rpm
error: open of MySQL-server-4.0.16-0.i386.rpm failed: No such file or directory
[root@inc-platform-dev-153-135 mysql]# rpm -ivh MySQL-server-5.5.25-1.rhel5.x86_64.rpm 
Preparing...                ########################################### [100%]
   1:MySQL-server           ########################################### [100%]

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h inc-platform-dev-153-135.hst.bjc.kfc.alidc.net password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

Please report any problems with the /usr/bin/mysqlbug script!

启动Server

[root@inc-platform-dev-153-135 mysql]# service mysql start
Starting MySQL..                                           [  OK  ]
[root@inc-platform-dev-153-135 mysql]# netstat -an|grep 3306
tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LIST

安装Client

[root@inc-platform-dev-153-135 mysql]# rpm -ivh MySQL-client-5.5.25-1.rhel5.x86_64.rpm 
Preparing...                ########################################### [100%]

3.修改mysql的root用户密码

[root@inc-platform-dev-153-135 mysql]# /usr/bin/mysqladmin -u root password \'javaman\' 

3.登录MySql
登录：

[root@inc-platform-dev-153-135 mysql]# mysql -u root -p javaman
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

无法登录要修改配置：

[root@inc-platform-dev-153-135 mysql]# service mysql stop

成功了.
4.远程登录
当企图远程登录mysql时候，有可能报错“Host'xxx.xxx.xxx.xx' is not allowed to connect to this MySQL server".在MySql Server 本机修改如下：

mysql> UPDATE user SET user='root' where host='localhost'; 
mysql> update user set host = '%' where user = 'root';
mysql> select host, user from user;
+------------------------------------------------+------+
| host                                           | user |
