Mysql的RPM包安装和导入测试文件

0 导入mysql 案例文件:

将文件 world.sql 上传到linux上

mysql>create database world; use world;

mysql> source /opt/world.sql

world.sql 见附件

1、解压RPM包

[root@hadoop3 ~]# mkdir /usr/local/mysql

[root@hadoop3 soft]# tar vxf MySQL-5.6.24-1.el6.x86_64.rpm-bundle.tar -C /usr/local/mysql

2、安装RPM包

[root@hadoop3 ~]# cd /usr/local/mysql

[root@hadoop3 mysql]# ls

MySQL-client-5.6.24-1.el6.x86_64.rpm MySQL-shared-5.6.24-1.el6.x86_64.rpm

MySQL-devel-5.6.24-1.el6.x86_64.rpm MySQL-shared-compat-5.6.24-1.el6.x86_64.rpm

MySQL-embedded-5.6.24-1.el6.x86_64.rpm MySQL-test-5.6.24-1.el6.x86_64.rpm

MySQL-server-5.6.24-1.el6.x86_64.rpm

[root@hadoop3 mysql]# rpm -ivh MySQL-client-5.6.24-1.el6.x86_64.rpm

[root@hadoop3 mysql]# rpm -ivh MySQL-server-5.6.24-1.el6.x86_64.rpm

-------------------------------------------------------------------------------------------------------------------------------------------------

补充：删除旧版本mysql

（1）[root@hadoop3 mysql]# rpm -qa|grep -i mysql

qt-mysql-4.6.2-25.el6.x86_64

mysql-server-5.1.66-2.el6_3.x86_64

mysql-5.1.66-2.el6_3.x86_64

mysql-libs-5.1.66-2.el6_3.x86_64

perl-DBD-MySQL-4.013-3.el6.x86_64

（2）删除相关组建

[root@hadoop3 mysql]# rpm -e --nodeps qt-mysql-4.6.2-25.el6.x86_64

[root@hadoop3 mysql]# rpm -e --nodeps mysql-server-5.1.66-2.el6_3.x86_64

[root@hadoop3 mysql]# rpm -e --nodeps mysql-5.1.66-2.el6_3.x86_64

[root@hadoop3 mysql]# rpm -e --nodeps mysql-libs-5.1.66-2.el6_3.x86_64

[root@hadoop3 mysql]# rpm -e --nodeps perl-DBD-MySQL-4.013-3.el6.x86_64

（3）删除目录及文件

-----------------------------------------------------------------------------------------

3、查看root用户的随机密码此时需要切换到root用户家目录

（1）[root@hadoop3 ~]# ls -la

-rw------- 1 root root 71 May 26 00:14 .my.cnf.2058

-rw------- 1 root root 1 May 26 00:14 .mysql.2058

-rw------- 1 root root 104 May 26 00:19 .mysql_secret

（2）[root@hadoop3 ~]# vi .mysql_secret

# The random password set for the root user at Tue May 26 00:19:14 2015 (local time): RoBd25NxiAWoBzGB

4、启动服务

[root@hadoop3 ~]# service mysql start

或

[root@hadoop3 ~]# /etc/init.d/mysql start

5、myql 安装 --这里会用到root的随机密码

[root@hadoop3 ~]# mysql_secure_installation

都yes就可以，在安装过程中，会先设置密码，然后再一路yes下去

6、修改my.cnf

（1）[root@hadoop3 usr]# find / -name my-default.cnf

/usr/share/mysql/my-default.cnf

/usr/share/doc/MySQL-server-5.6.24/my-default.cnf

（2）[root@hadoop3 usr]# cp /usr/share/doc/MySQL-server-5.6.24/my-default.cnf /etc/my.cnf

（3）[root@hadoop3 ~]# vi /etc/my.cnf

[mysql]

default-character-set = utf8 ----> 默认是latin

auto-rehash

[mysqld]

basedir = /usr

datadir = /var/lib/mysql

port = 3306

log_bin=/var/lib/mysql/1.000001

binlog_format=ROW

expire_logs_days = 5

slow_query_log = 1

slow_query_log_file = /var/lib/mysql/mysqlslow.log

long_query_time = 2

innodb_log_buffer_size = 5M

innodb_file_per_table=0

innodb_data_file_path=ibdata1:10M:autoextend

innodb_buffer_pool_size=500M

character_set_server = utf8 ----> 默认是latin

socket=/var/lib/mysql/mysql.sock

[mysqld_safe]

log-error=/var/lib/mysql/mysqlerror.log

[mysqldump]

quick

max_allowed_packet = 16M

（4）软连接

[root@hadoop3 ~]# ln -s /tmp/mysqld.sock /var/lib/mysql/mysql.sock

7、重启连接mysql

[root@hadoop3 ~]# service mysql restart

[root@hadoop3 ~]# mysql -uroot -p123456 (这里设置的mysql密码为123456)

8、说明

建议使用root用户，这里使用mysql为MySQL-5.6.24-1.el6.x86_64.rpm-bundle.tar

机器别名为hadoop3。

启动后，通过命令 service mysql status来看是否运行

在安装好后，如果通过sqlyog等客户端来链接时，会报链接遭拒，可以做如下修改：

mysql命令行下:

例如，你想root使用123456从任何主机连接到mysql服务器的话。
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
FLUSH   PRIVILEGES;




如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

上面在 /etc/my.cnf 中修改了mysql默认字符集，这样使用MySQL时有汉字也不会乱码了

查看mysql 使用的字符集：

mysql> show variables like 'character%';

+--------------------------+----------------------------+

| Variable_name | Value |

+--------------------------+----------------------------+

| character_set_client | utf8 |

| character_set_connection | utf8 |

| character_set_database | utf8 |

| character_set_filesystem | binary |

| character_set_results | utf8 |

| character_set_server | utf8 |

| character_set_system | utf8 |

| character_sets_dir | /usr/share/mysql/charsets/ |

+--------------------------+----------------------------+
