centos6.8 安装mysql 5.6

一、检查系统是否安装其他版本的MysqL数据

#yum list installed | grep MysqL
#yum -y remove MysqL-libs.x86_64

二、安装及配置

# wget http://repo.MysqL.com/MysqL-community-release-el6-5.noarch.rpm
# rpm -ivh MysqL-community-release-el6-5.noarch.rpm
# yum repolist all | grep MysqL

安装MysqL数据库

# yum install MysqL-community-server -y

设置为开机启动(2、3、4都是on代表开机自动启动)

# chkconfig --list | grep MysqLd
# chkconfig MysqLd on

三、设置远程root
启动MysqL

# service MysqLd start

设置root密码

# MysqL_secure_installation

登陆root账号

# MysqL -uroot -p 

建立远程root用户

MysqL> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你设置的密码' WITH GRANT OPTION;
MysqL> flush privileges;

四、设置utf-8编码

查看MysqL原本编码：

MysqL> show variables like 'character%';

设置编码

# vi /etc/my.cnf

如下(少补)：

[MysqLd]
character-set-server=utf8 
collation-server=utf8_general_ci 

[MysqL]
default-character-set = utf8

[MysqL.server]
default-character-set = utf8


[MysqLd_safe]
default-character-set = utf8


[client]
default-character-set = utf8

重启MysqL

# service MysqLd restart

再次查看编码：

     # MysqL -uroot -p
MysqL> show variables like 'character%';
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

允许所有外部链接访问（可选）

MysqL -u root -p

MySQL命令行输入

GRANT ALL PRIVILEGES ON *.* TO 'root'@%' IDENTIFIED BY 123456' WITH GRANT OPTION;
FLUSH PRIVILEGES;
