centOS6.6系统中rpm安装MySQL-5.6.30

RPM方式安装MySQL5.6.30

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：CentOS6.6_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 16:43 MySQL-client-5.6.30-1.linux_glibc2.5.x86_64.rpm`

4	`-rw-r--r--. 1 root root 3340660 Dec 11 16:43 MySQL-devel-5.6.30-1.linux_glibc2.5.x86_64.rpm`

5	`-rw-r--r--. 1 root root 54360600 Dec 11 16:43 MySQL-server-5.6.30-1.linux_glibc2.5.x86_64.rpm`

c. 安装MySQL

1	`[root@localhost rpm]# rpm -ivh MySQL-server-5.6.30-1.linux_glibc2.5.x86_64.rpm`

2	`[root@localhost rpm]# rpm -ivh MySQL-devel-5.6.30-1.linux_glibc2.5.x86_64.rpm`

3	`[root@localhost rpm]# rpm -ivh MySQL-client-5.6.30-1.linux_glibc2.5.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	`+-----------------------+------+-------------------------------------------+`

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.

[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
