1. linux環境下mysql的安裝
1. sudo yum install mysql-server
2. 修改配置文件
1. vim /etc/my.cnf
1. 添加default-character-set = utf8
3. 設置mysql隨系統自動啟動
2. 檢查設置是否正確
1. sudo chkconfig --list mysqld
1. mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
   
2. 2-5都是啟動則ok
4. 啟動mysql
1. sudo service mysqld start
1. 如果出現錯誤 MySQL Daemon failed to start. 請參考
1. http://blog.csdn.net/u012286517/article/details/50436740


2. 刪除匿名用戶
1. select user,host from mysql.user;
1. +------+--------------------+
2. | user | host |
3. +------+--------------------+
4. | root | 127.0.0.1 |
5. | | localhost |
6. | root | localhost |
7. | | vm\_24\_26\_centos |
8. | root | vm\_24\_26\_centos |
9. +------+--------------------+
2. delete from mysql.user where user=‘‘;
3. 刷新一下權限
1. flush privileges;
4. 在防火墻下面開放3306端口,開放給外網
1. sudo vim /etc/sysconfig/iptables
1. #mysql port
2. -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
2. 重啟防火墻
1. service iptables restart
   
5. 重新登錄mysql
1. mysql -u root
6. 創建一個非root權限的賬戶，避免使用root
1. insert into mysql.user(Host,User,Password)values("localhost","mmall",password("mmall"
   ));
2. 檢查插入是否正確
1. select user,host from mysql.user;
1. +-------+--------------------+
2. | user | host |
3. +-------+--------------------+
4. | root | 127.0.0.1 |
5. | mmall | localhost |
6. | root | localhost |
7. | root | vm\_24\_26\_centos |
8. +-------+--------------------+
7. 創建一個數據庫
1. create database `mmall` default character set utf8 collate utf8_general_ci;
8. 查看權限
1. select * from mysql.user \G
9. 賦予權限
1. 切換數據庫 use mmall;
2. grant all privileges on mmall.* to mmall@‘%‘ identified by ‘mmall‘ with grant option;
1. 註意，此語句可能有錯誤，導致執行下面的權限查詢的時候出現授權不起作用的現象，可以改為下面的授權語句。
1. grant all privileges on *.* to mmall@‘%‘ identified by ‘mmall‘ with grant option;
2. 請參看
1. https://bbs.csdn.net/topics/330154879
   
3. 可以更細化權限為
1. grant select,delete,create on mmall.* to mmall@‘%‘ identified by ‘mmall‘ with grant option;
10. 重新查看全新
1. 1. select * from mysql.user \G
   
   
   
11. 修改root賬號的密碼
1. set password for root@localhost=password(‘root‘);
2. set password for [email protected]=password(‘root‘);
   
3. select user,host,password from mysql.user;
12. 退出重新登錄
1. 使用密碼登錄，否則沒有權限
5. win下安裝mysql
1. 略
