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)： 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)
