RPM方式安裝MySQL5.6

RPM方式安裝MySQL5.6

1. 檢查MySQL及相關RPM包，是否安裝，若是有安裝，則移除（rpm –e 名稱）

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

注：rpm -e --nodeps mysql-libs

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

[root@localhost 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

[root@localhost rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm
[root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm
[root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm

4. 修改配置文件位置

[root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

5. 初始化MySQL及設置密碼

root@localhost rpm]# /usr/bin/mysql_install_db
[root@localhost rpm]# service mysql start
[root@localhost rpm]# cat /root/.mysql_secret  #查看root帳號密碼
# The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl
[root@localhost ~]# mysql -uroot –pqKTaFZnl
mysql> SET PASSWORD = PASSWORD('123456');    #設置密碼爲123456
mysql> exit
[root@localhost ~]# mysql -uroot -p123456

6. 容許遠程登錄

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

7. 設置開機自啓動

root@localhost ~]# chkconfig mysql on
[root@localhost ~]# chkconfig --list | grep mysql
mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

8. MySQL的默認安裝位置

/var/lib/mysql/               #數據庫目錄
/usr/share/mysql              #配置文件目錄
/usr/bin                      #相關命令目錄
/etc/init.d/mysql             #啓動腳本

9. 修改字符集和數據存儲路徑，配置/etc/my.cnf文件,修改數據存放路徑，mysql.sock路徑以及默認編碼utf-8.

[mysqld]
port            = 3306
character_set_server=utf8
character_set_client=utf8
collation-server=utf8_general_ci
#(注意linux下mysql安裝完後是默認：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
#(設置最大鏈接數，默認爲 151，MySQL服務器容許的最大鏈接數16384; )
max_connections=1000

[mysql]
default-character-set = utf8

[client]
port            = 3306
default-character-set=utf8

10. 查看字符集

show variables like '%collation%';

show variables like '%char%';
