1.检查MySQL及相关RPM包
检查MySQL及相关RPM包，是否安装，如果有安装，则移除（rpm –e 名称）
-
[root@localhost ~]# rpm -qa | grep -i mysql
-
mysql-libs-5.1.66-2.el6_3.x86_64
-
[root@localhost ~]# yum -y remove mysql-libs*
2.下载rpm包
下载Linux对应的RPM包，如：CentOS6.4_64对应的RPM包，如下：[plain] view plain copy
-
[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. 安装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
4. 初始化MySQL及设置密码
-
[root@localhost rpm]# /usr/bin/mysql_install_db
-
[root@localhost rpm]# service mysql start
-
[root@localhost rpm]# cat /root/.mysql_secret #查看root账号密码
-
# 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'); #设置密码为123456
-
mysql> exit
-
[root@localhost ~]# mysql -uroot -p123456
5. 允许远程登陆
-
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. 设置开机自启动
-
[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
7. MySQL的默认安装位置
-
/var/lib/mysql/ #数据库目录
-
-
/usr/share/mysql #配置文件目录
-
-
/usr/bin #相关命令目录
-
-
/etc/init.d/mysql #启动脚本
8.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.
-
[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
9.查看字符集
-
show variables like '%collation%';
-
-
show variables like '%char%';
