RPM方式安装MySQL5.6
1. 检查MySQL是否安装，如果有安装，则移除（rpm –e 名称）
[[email protected] ~]# rpm -qa | grep -i mysql
mysql-libs-xxxxxxxxxx.x86_64
[[email protected] ~]# yum -y remove mysql-libs*
2. 安装MySQL,并修改配置文件位置
[[email protected] rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm
#MySQL-client - MySQL 客户端程序，用于连接并操作Mysql服务器。
[[email protected] rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm
#MySQL-devel - 库和包含文件，如果你想要编译其它MySQL客户端，例如Perl模块，则需要安装该RPM包。
[[email protected] rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm
#修改配置文件位置
[[email protected] rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
3.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=500
[mysql]
default-character-set = utf8
4. 初始化MySQL及设置密码
[[email protected] rpm]# /usr/bin/mysql_install_db
[[email protected] rpm]# service mysql start
[[email protected] 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): admin
[[email protected] ~]# mysql -u root –p admin
mysql> SET PASSWORD = PASSWORD(‘123456‘); #设置密码为123456
mysql> exit
[[email protected] ~]# 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
[[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
