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
|
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，注意：如果安装mysql-service出错，需要yum -y remove mysql-libs-*
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
|
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
|
8 |
[root@localhost ~] # mysql -uroot -p123456
|
e. 允许远程登陆
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 |
+-----------------------+------+-------------------------------------------+ |
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; |
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
2 |
/usr/share/mysql #配置文件目录
|
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.
[html] view plain copy
- [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
查看字符集
show variables like '%collation%';
show variables like '%char%';
