安装

进入安装包所在目录,解压文件

cd /home
tar -zxvf mysql-5.7.13-linux-glibc2.5-x86_64.tar.gz 

重命名

mv mysql-5.7.13-linux-glibc2.5-x86_64 mysql-5.7.13

 

添加系统mysql组和mysql用户

检查mysql组和用户是否存在,如无创建

cat /etc/group | grep mysql
#类似
mysql:x:490:
cat /etc/passwd | grep mysql
#类似
mysql:x:496:490::/home/mysql:/bin/bash

以上为存在的情况,如无,执行添加命令:

groupadd mysql
useradd -r -g mysql mysql
#useradd -r参数表示mysql用户是系统用户,不可用于登录系统

安装数据库

创建data目录

cd mysql-5.7.13
mkdir data

将/home/mysql/mysql-5.7.13的所有者及所属组改为mysql

chown -R mysql.mysql /home/mysql-5.7.13

修改/home/mysql-5.7.13/support-files目录下配置文件my-default.cnf

并复制以下信息至my-default.cnf

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

[mysqld]
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 
#lower_case_table_names=1 
basedir = /home/mysql-5.7.13
datadir = /home/mysql-5.7.13/data
port = 3306
socket = /tmp/mysql.sock
character-set-server=utf8
 
log-error = /home/mysql-5.7.13/data/mysqld.log
pid-file = /home/mysql-5.7.13/data/mysqld.pid

拷贝,如果提示是否覆盖,y

cp support-files/my-default.cnf /etc/my.cnf

 

初始化 mysqld

cd /home/mysql-5.7.13
./bin/mysqld --initialize --user=mysql --basedir=/home/mysql-5.7.13/ --datadir=/home/mysql-5.7.13/data/ 

 

初始化完成之后,查看日志

/home/mysql-5.7.13/data/mysqld.log

临时密码

A temporary password is generated for root@localhost: Bjs!&sjbX9Kq

把启动脚本放到开机初始化目录

cp support-files/mysql.server /etc/init.d/mysql

启动mysql服务

service mysql start

创建软连接  ln -s /home/mysql-5.7.13/bin/mysql /usr/bin

登录mysql,密码为初始密码

cd /home/mysql-5.7.13
./bin/mysql -u root -p

修改密码

mysql> set password=password('1234.ecp');
mysql> grant all privileges on *.* to root@'%' identified by '1234.ecp';
mysql> flush privileges;

添加远程访问权限 

mysql> use mysql;
mysql> update user set host='%' where user = 'root';
mysql> flush privileges;

重启mysql生效

service mysql stop
service mysql start

or

service mysql restart

 

mysql数据的导出和导入

cd /home/mysql-5.7.13/bin

导出整个数据库中的所有数据

./mysqldump -u userName -p  dabaseName  > fileName.sql

导出数据库中的某个表的数据

./mysqldump -u userName -p  dabaseName tableName > fileName.sql 

导出整个数据库中的所有的表结构

./mysqldump -u userName -p -d dabaseName  > fileName.sql

导出整个数据库中某个表的表结构

./mysqldump -u userName -p -d dabaseName tableName > fileName.sql

 

导入mysql方法1

./mysql -uroot -p
source fileName.sql

导入mysql方法2

./mysql -uroot -p database < fileName.sql
