RPM方式安装MySQL5.6

a. 检查MySQL及相关RPM包，是否安装，如果有安装，则移除（rpm –e 名称）

1
[root@localhost
~]
#
rpm -qa | grep -i mysql
2
mysql-libs-5.1.66-2.el6_3.x86_64
3
[root@localhost
~]
#
yum -y remove mysql-libs*
b. 下载Linux对应的RPM包，如：CentOS6.4_64对应的RPM包，如下：

1
[root@localhost
rpm]
#
ll
2
total
74364
3
-rw-r--r--.
1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm
4
-rw-r--r--.
1 root root  3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm
5
-rw-r--r--.
1 root root 54360600 Dec 11 20:03 MySQL-server-5.6.15-1.el6.x86_64.rpm
c. 安装MySQL

1
[root@localhost
rpm]
#
rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm
2
[root@localhost
rpm]
#
rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm
3
[root@localhost
rpm]
#
rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm
4
#修改配置文件位置
5
[root@localhost
rpm]
#
cp /usr/share/mysql/my-default.cnf /etc/my.cnf
d. 初始化MySQL及设置密码

1
[root@localhost
rpm]
#
/usr/bin/mysql_install_db
2
[root@localhost
rpm]
#
service mysql start
3
[root@localhost
rpm]
#
cat /root/.mysql_secret  #查看root账号密码
4
#
The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl
5
[root@localhost
~]
#
mysql -uroot –pqKTaFZnl
6
mysql>
SET PASSWORD = PASSWORD(
'123456'
);
#设置密码为123456
7
mysql>
exit
8
[root@localhost
~]
#
mysql -uroot -p123456
e. 允许远程登陆

01
mysql>
use mysql;
02
mysql>
select
host,user,password
from user;
03
+-----------------------+------+-------------------------------------------+
04
|
host                  | user | password                                  |
05
+-----------------------+------+-------------------------------------------+
06
|
localhost             | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
07
|
localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

set
password=password(
'123456'
)
where user=
'root'
;
13
mysql>
update user
set
host=
'%'
where
user=
'root'
and
host=
'localhost'
;
14
mysql>
flush privileges;
15
mysql>
exit
f. 设置开机自启动

1
[root@localhost
~]
#
chkconfig mysql on
2
[root@localhost
~]
#
chkconfig --list | grep mysql
3
mysql
0:off   1:off   2:on    3:on    4:on    5:on    6:off
g. MySQL的默认安装位置

1
/var/lib/mysql/
#数据库目录
2
/usr/share/mysql
#配置文件目录
3
/usr/bin
#相关命令目录
4
/etc/init.d/mysql
#启动脚本
修改字符集和数据存储路径

配置/etc/my.cnf文件,修改数据存放路径、mysql.sock路径以及默认编码utf-8.

[html] view
plain copy







[client]

password = 123456

port = 3306

default-character-set=utf8

[mysqld]

port = 3306

character_set_server=utf8

character_set_client=utf8

collation-server=utf8_general_ci

#(注意linux下mysql安装完后是默认：表名区分大小写，列名不区分大小写； 0：区分大小写，1：不区分大小写)

lower_case_table_names=1

#(设置最大连接数，默认为 151，MySQL服务器允许的最大连接数16384; )

max_connections=1000

[mysql]

default-character-set = utf8

查看字符集

show variables like '%collation%';

show variables like '%char%';

h:执行上面的命令之后，发现用小海豚连接还是连接不上，需要执行如下的命令

[root@localhost
rpm]
mysql -uroot -p123456
[root@localhost
rpm]
mysql>use mysql

Reading table information for completion of table and column names

You can turn off this feature to get a quicker startup with -A

Database changed

mysql>select 'host' from user where user='root'

-> ;

+------+

| host |

+------+

| host |

| host |

| host |

| host |

+------+

4 rows in set (0.00 sec)

mysql>update user set host = '%' where user = 'root';

ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

Query OK, 0 rows affected (0.00 sec)

mysql>quit

Bye

[root@localhost mysql]# service mysql restart

Shutting down MySQL.. SUCCESS!

Starting MySQL.. SUCCESS!
