centos7 mysql數據庫安裝和配置

一、安裝yum源，已經下載安裝包
------------------------------------------------
rpm -ivh epel-release-latest-7.noarch.rpm
------------------------------------------------
二、安裝vim

yum -y install vim
------------------------------------------------
yum -y install wget
------------------------------------------------
yum -y install ruby
------------------------------------------------
三、Linux下添加磁盤、掛載，見掛載詳情
------------------------------------------------
注意：關閉防火牆 systemctl stop firewalld.service
------------------------------------------------
四、mysql安裝

五、官網下載安裝mysql-server
5.1 官網下載rpm包 https://dev.mysql.com/downloads/repo/yum/
安裝wget
yum -y install wget

# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server

六、安裝成功後重啓mysql服務

service mysqld restart

mysql_secure_installation（設置密碼）

初次安裝mysql，root帳戶沒有密碼

查看密碼 cat /var/log/mysqld.log | grep password
grep 'temporary password' /var/log/mysqld.log

首次登陸，修改密碼：修改密碼 set password for 'root'@'localhost' =password('your password');

查看安裝路徑 whereis mysql

mysql 登陸mysql：mysql -u root -p
密碼：ShiQq!123456
mariadb 密碼：Seari@123456
查看密碼 cat /var/log/mysqld.log | grep password
修改密碼 set password for 'root'@'localhost' =password('password');
查看安裝路徑 whereis mysql
重啓mysql：service mysqld restart

自啓動mysql：systemctl enable mysqld

七、配置mysql，這裏的字符編碼必須和/usr/share/mysql/charsets/Index.xml中一致
詳見：http://www.cnblogs.com/starof/p/4680083.html

八、遠程鏈接設置
把在全部數據庫的全部表的全部權限賦值給位於全部IP地址的root用戶。
mysql> grant all privileges on *.* to root@'%'identified by 'password';
若是是新用戶而不是root，則要先新建用戶
mysql>create user 'username'@'%' identified by 'password';
此時就能夠進行遠程鏈接了。

用navicat，登陸
