RPM方式安装MySQL5.6源码

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）

[root@localhost ~]# rpm -qa | grep -i mysql
mysql-libs-5.1.66-2.el6_3.x86_64
[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：

[root@localhost rpm]# ll
total 74364
-rw-r--r--. 1 root root 18442536 dec 11 20:19 mysql-client-5.6.15-1.el6.x86_64.rpm
-rw-r--r--. 1 root root 3340660 dec 11 20:06 mysql-devel-5.6.15-1.el6.x86_64.rpm
-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

[root@localhost rpm]# rpm -ivh mysql-server-5.6.15-1.el6.x86_64.rpm
[root@localhost rpm]# rpm -ivh mysql-devel-5.6.15-1.el6.x86_64.rpm
[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

d. 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): qktafznl
[root@localhost ~]# mysql -uroot –pqktafznl
mysql> set password = password('123456'); #设置密码为123456
mysql> exit
[root@localhost ~]# mysql -uroot -p123456

e. 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

f. 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

g. 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

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.

[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%';
