1.root使用者登入Linux，使用yum 命令安裝MySQL，安裝完畢後，mysql 資料庫路徑在/var/lib/mysql ，配置檔案路徑為/etc/my.cnf

sudo yum install mysql
sudo yum install mysql-server
sudo yum install mysql-devel

sudo chgrp -R mysql /var/lib/mysql
chmod -R 770 /var/lib/mysql

sudo service mysqld start

/usr/bin/mysqladmin -u root password '你的密碼'

（1）進入mysql，先檢視當前資料庫編碼狀態

SHOW VARIABLES LIKE 'character_set_%';

+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     |
 
 utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | latin1                     |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | latin1                     |
 

| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

（2）編碼修改

set character_set_server=utf8;

set character_set_database=utf8;

mysql> SHOW VARIABLES LIKE 'character_set_%';
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+

至此，MySQL服務的安裝和大致配置就已完成，另外要注意啟用mysql的預設埠3306。其他若有問題，再具體回覆說明！
