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
sql_mode=’NO_ENGINE_SUBSTITUTION’
[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/ |
