MySQL5.6在Centos6.5下安裝圖文說明教程

1.下載Linux對應的RPM包

2.解壓tar包

tar -xvf MySQL-5.6.33-1.el6.x86_64.rpm-bundle.tar

3.安裝MySQL

rpm -ivh MySQL-server-5.6.33-1.el6.x86_64.rpm 
rpm -ivh MySQL-client-5.6.33-1.el6.x86_64.rpm 
rpm -ivh MySQL-devel-5.6.33-1.el6.x86_64.rpm

如果出現:

error: Failed dependencies:
    libaio.so.1()(64bit) is needed by MySQL-server-5.6.33-1.el6.x86_64
    libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.33-1.el6.x86_64
    libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.33-1.el6.x86_64

下載libaio

yum install libaio

如果出現:

error: Failed dependencies:
    libnuma.so.1()(64bit) is needed by MySQL-server-5.6.33-1.el6.x86_64
    libnuma.so.1(libnuma_1.1)(64bit) is needed by MySQL-server-5.6.33-1.el6.x86_64
    libnuma.so.1(libnuma_1.2)(64bit) is needed by MySQL-server-5.6.33-1.el6.x86_64

下載numactl

yum install numactl

4.初始化MySQL及設置密碼

/usr/bin/mysql_install_db
service mysql start

如果啟動失敗可能是數據塊所在目錄沒有權限

cat /root/.mysql_secret #查看root賬號密碼
mysql> SET PASSWORD = PASSWORD('123456');
mysql> exit

如果.mysql_secret文件不存在,先停止MySQL進入安全模式設置密碼

service mysql stop
mysqld_safe --skip-grant-tables&
mysql -u root mysql
mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';
mysql> FLUSH PRIVILEGES;

5.允許遠程登陸

mysql> use mysql;
mysql> select host,user,password from user;
mysql> update user set host='%' where user='root' and host='localhost';
mysql> flush privileges;
mysql> exit

6.設置開機自啟動

chkconfig mysql on
chkconfig --list   grep mysql
mysql      0:off  1:off  2:on  3:on  4:on  5:on  6:off

7.MySQL的默認安裝位置

/var/lib/mysql/        #數據庫目錄
/usr/share/mysql       #配置文件目錄
/usr/bin           #相關命令目錄
/etc/init.d/mysql       #啟動腳本

8.常用命令

1.使用客戶端工具連接到數據庫

mysql -u root -p

2.查看MySQL服務器中包含那些數據庫

mysql>SHOW DATABASES;

3.查看數據庫中的數據表信息

mysql>SHOW TABLES;

4.切換數據庫

mysql>USE mysql;

5.創建新的數據庫

mysql>CREATE DATABASE 數據庫名字;

6.創建新的數據表

mysql>CREATE TABLE 表名 (字段定義)

7.刪除一個數據表

mysql>DROP TABLE 數據庫名.表名;

8.刪除一個數據庫

mysql>DROP DATABASE 數據庫名

9.備份整個數據庫

mysqldump -u root -p auth > mysql-auth.sql

10.備份數據庫MYSQL中的user表

mysqldump -u root -p mysql user > mysql.host-user.sql

11.備份MYSQL服務器中所有數據庫

mysqldump -u root -p -all-databases > mysql-all.sql

12.恢復數據庫

mysql -u root -p [數據庫名]< mysql-all.sql

13.授予用戶權限

GRANT 權限列表 ON 數據庫名.表名 TO 用戶名@來源地址 [IDENTIFIED BY '密碼']
GRANT SELECT ON mysql.user TO daxiong@'localhost' IDENTIFIED BY'123456';
