RPM方式安装MySQL5.6

a. 检查及相关RPM包，是否安装，如果有安装，则移除（rpm –e 名称）

1 [root@localhost ~]# rpm -qa | grep -i mysql2 mysql-libs-5.1.66-2.el6_3.x86_643 [root@localhost ~]# yum -y remove mysql-libs*

 

b. 下载对应的RPM包，如：CentOS6.4_64对应的RPM包，如下：

1 [root@localhost rpm]# ll2 total 743643 -rw-r--r--. 1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm4 -rw-r--r--. 1 root root  3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm5 -rw-r--r--. 1 root root 54360600 Dec 11 20:03 MySQL-server-5.6.15-1.el6.x86_64.rpm

c. 安装MySQL

1 [root@localhost rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm2 [root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm3 [root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm4 #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及设置密码

1 [root@localhost rpm]# /usr/bin/mysql_install_db2 [root@localhost rpm]# service mysql start3 [root@localhost rpm]# cat /root/.mysql_secret  #查看root账号密码4 # The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl5 [root@localhost ~]# mysql -uroot –pqKTaFZnl6 mysql> SET PASSWORD = PASSWORD('123456');    #设置密码为1234567 mysql> exit8 [root@localhost ~]# mysql -uroot -p123456

 

e. 允许远程登陆

1 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. 设置开机自启动

1 [root@localhost ~]# chkconfig mysql on2 [root@localhost ~]# chkconfig --list | grep mysql3 mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

 

g. MySQL的默认安装位置

 

1 /var/lib/mysql/               #数据库目录2 /usr/share/mysql              #配置文件目录3 /usr/bin                     #相关命令目录4 /etc/init.d/mysql              #启动脚本

 

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.

1 [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)  11 lower_case_table_names=1  12 #(设置最大连接数，默认为 151，MySQL服务器允许的最大连接数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%';
