AWS Linux下MySQL数据库的安装与配置

1.root用户登入Linux，使用yum 命令安装MySQL，安装完毕后，mysql 数据库路径在/var/lib/mysql ，配置文件路径为/etc/my.cnf

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

2..将 /var/lib/mysql的 用户群改成mysql，并赋予属主和属组权限

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

3.启动mysql服务，设置登录mysql的用户、密码

sudo service mysqld start

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

4. 设置mysql编码

（1）进入mysql，先查看当前数据库编码状态

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）编码修改

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服务的安装和大致配置就已完成，另外要注意启用mysql的默认端口3306。其他若有问题，再具体回复说明！
