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

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)：

复制代码[mysqld]character-set-server=utf8 collation-server=utf8_general_ci performance_schema_max_table_instances=400 table_definition_cache=400 table_open_cache=256

修改

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,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复制代码

重启mysql

service mysqld restart

再次查看编码：

复制代码

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)
