RPM方式安裝MySQL5.6

1.檢查MySQL及相關RPM包

檢查MySQL及相關RPM包，是否安裝，如果有安裝，則移除（rpm –e 名稱）

[[email protected] ~]# rpm -qa | grep -i mysql
mysql-libs-5.1.66-2.el6_3.x86_64
[[email protected] ~]# yum -y remove mysql-libs*

2.下載rpm包

 下載Linux對應的RPM包，如：CentOS6.4_64對應的RPM包，如下：

[[email protected] rpm]# ll
total 74364
-rw-r--r--. 1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm
-rw-r--r--. 1 root root  3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm
-rw-r--r--. 1 root root 54360600 Dec 11 20:03 MySQL-server-5.6.15-1.el6.x86_64.rpm
 

3. 安裝MySQL

[[email protected] rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm
[[email protected] rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm
[[email protected] rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm
#修改配置檔案位置
[[email protected] rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
 

4. 初始化MySQL及設定密碼

[[email protected] rpm]# /usr/bin/mysql_install_db
[[email protected] rpm]# service mysql start
[[email protected] rpm]# cat /root/.mysql_secret  #檢視root賬號密碼
# The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl
[[email protected]
 
 ~]# mysql -uroot –pqKTaFZnl
mysql> SET PASSWORD = PASSWORD('123456');    #設定密碼為123456
mysql> exit
[[email protected] ~]# mysql -uroot -p123456

5. 允許遠端登陸

mysql> use mysql;

mysql> select host,user,password from user;

+-----------------------+------+-------------------------------------------+

| host                  | user | password                                  |

+-----------------------+------+-------------------------------------------+

| localhost             | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

| localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

| 127.0.0.1             | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

| ::1                   | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

+-----------------------+------+-------------------------------------------+

 

mysql> update user set password=password('123456') where user='root';

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

mysql> flush privileges;

mysql> exit

6. 設定開機自啟動

[[email protected] ~]# chkconfig mysql on

[[email protected] ~]# chkconfig --list | grep mysql

mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

7. MySQL的預設安裝位置

/var/lib/mysql/               #資料庫目錄

/usr/share/mysql              #配置檔案目錄

/usr/bin                     #相關命令目錄

/etc/init.d/mysql              #啟動指令碼

8.修改字符集和資料儲存路徑

配置/etc/my.cnf檔案,修改資料存放路徑、mysql.sock路徑以及預設編碼utf-8.

[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安裝完後是預設：表名區分大小寫，列名不區分大小寫； 0：區分大小寫，1：不區分大小寫)
lower_case_table_names=1
#(設定最大連線數，預設為 151，MySQL伺服器允許的最大連線數16384; )
max_connections=1000
[mysql]
default-character-set = utf8

9.檢視字符集

show variables like '%collation%';

show variables like '%char%';

10、溫馨提示
