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 mysql-libs-5.1.66-2.el6_3.x86_64 [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 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
c. 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 #修改配置文件位置 [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 [root@localhost rpm]# service mysql start [root@localhost rpm]# cat /root/.mysql_secret #查看root賬號密碼 # 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'); #設置密碼為123456 mysql> exit [root@localhost ~]# mysql -uroot -p123456
e. 允許遠程登陸
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
f. 設置開機自啟動
[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
g. 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 #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]
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)
lower_case_table_names=1
#(設置最大連接數，默認為 151，MySQL服務器允許的最大連接數16384; )
max_connections=1000
[mysql]
default-character-set = utf8
查看字符集
show variables like '%collation%';
show variables like '%char%';
