RPM方式安裝MySQL5.6

RPM方式安裝MySQL5.6

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

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

[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. 安裝MySQL

[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及設置密碼

[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賬號密碼 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'); #設置密碼為123456 7 mysql> exit 8 [root@localhost ~]# mysql -uroot -p123456

 

e. 允許遠程登陸

mysql> use mysql;  2 mysql> select host,user,password from user;  3 +-----------------------+------+-------------------------------------------+  4 | host | user | password |  5 +-----------------------+------+-------------------------------------------+  6 | localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |  7 | localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |  8 | 127.0.0.1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |  9 | ::1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 | 10 +-----------------------+------+-------------------------------------------+ 11 12 mysql> update user 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. 設置開機自啟動

[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的默認安裝位置

 

/var/lib/mysql/ #數據庫目錄 2 /usr/share/mysql #配置文件目錄 3 /usr/bin #相關命令目錄 4 /etc/init.d/mysql #啟動腳本

 

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.

[client]  2 password = 123456  3 port = 3306  4 default-character-set=utf8  5 [mysqld]  6 port = 3306  7 character_set_server=utf8  8 character_set_client=utf8  9 collation-server=utf8_general_ci 10 #(注意linux下mysql安裝完后是默認：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) 11 lower_case_table_names=1 12 #(設置最大連接數，默認為 151，MySQL服務器允許的最大連接數16384; ) 13 max_connections=1000 14 [mysql] 15 default-character-set = utf8 

 

查看字符集

show variables like '%collation%';

show variables like '%char%';
