yum安装mysql5.6

1.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

2.安装及配置

wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
rpm -ivh mysql-community-release-el6-.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

3.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 c

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;

4.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/ |
+--------------------------+----------------------------+
 rows in set (0.00 sec)

5.加入环境变量，编辑 /etc/profile，这样可以在任何地方用mysql命令

export PATH=$PATH:/usr/local/mysql//bin<br>source /etc/profile
