MySQL - RPM method to install MySQL5.6 code examples detailed explanation

Install MySQL5.6 in RPM mode

1. Check MySQL and related RPM packages

Check MySQL and related RPM packages to see if they are installed. If they are installed, then Remove (rpm -e name)

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

2. Download the rpm package

Download the RPM package corresponding to Linux, such as the RPM package corresponding to CentOS6.4_64, as follows:

[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

3. Install 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

4. Initialize MySQL and set password

[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

5. Allow remote login

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

6. Set up auto-start at boot

[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

7. The default installation location of MySQL

/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

8. Modify characters Set and data storage path

Configure the /etc/my.cnf file, modify the data storage path, mysql.sock path and the default encoding 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

9. View character set

show variables like '%collation%';

show variables like '%char%';
