RPM方式安装MySQL5.6
a. 检查MySQL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 mysql |
2 |
mysql-libs-5.1.66-2.el6_3.x86_64 |
3 |
[root@localhost ~]# yum -y remove mysql-libs* |
b. 下载Linux对应的RPM包，如：CentOS6.4_64对应的RPM包，如下：
1 |
[root@localhost rpm]# ll |
2 |
total 74364 |
3 |
-rw-r--r--. 1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm |
4 |
-rw-r--r--. 1 root root 3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm |
5 |
-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.rpm |
2 |
[root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm |
3 |
[root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm |
4 |
#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_db |
2 |
[root@localhost rpm]# service mysql start |
3 |
[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): qKTaFZnl |
5 |
[root@localhost ~]# mysql -uroot –pqKTaFZnl |
6 |
mysql> SET PASSWORD = PASSWORD(‘123456‘); #设置密码为123456 |
7 |
mysql> exit |
8 |
[root@localhost ~]# mysql -uroot -p123456 |
e. 允许远程登陆
01 |
mysql> use mysql; |
02 |
mysql> select host,user,password from user; |
03 |
+-----------------------+------+-------------------------------------------+ |
04 |
| host | user | password | |
05 |
+-----------------------+------+-------------------------------------------+ |
06 |
| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | |
07 |
| localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 | |
08 |
| 127.0.0.1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 | |
09 |
| ::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 on |
2 |
[root@localhost ~]# chkconfig --list | grep mysql |
3 |
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.
查看字符集
show variables like ‘%collation%‘;
show variables like ‘%char%‘;
