MySQL5.6安装(RPM)笔记

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


2. 安装MySQL,并修改配置文件位置
[root@localhost 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。
[root@localhost 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。
[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


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
[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): admin
[root@localhost ~]# mysql -u root –p admin
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
