一、检查系统是否安装其他版本的MYSQL数据
1 # yum list installed | grep mysql 2 # yum -y remove mysql-libs.x86_64
二、安装及配置
1 # wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm 2 # rpm -ivh mysql-community-release-el6-5.noarch.rpm 3 # yum repolist all | grep mysql
安装MYSQL数据库
1 # 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)
1 # chkconfig --list | grep mysqld 2 # chkconfig mysqld on
三、设置远程root
启动mysql
1 # service mysqld start
设置root密码
1 # mysql_secure_installation
登录root账号
1 # mysql -uroot -p
建立远程root用户
1 mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你设置的密码' WITH GRANT OPTION; 2 mysql> flush privileges;
四、设置utf-8编码
查看mysql原本编码：
1 mysql> show variables like 'character%';
设置编码 vi /etc/my.cnf
1 [mysqld] 2 character-set-server=utf8 3 collation-server=utf8_general_ci 4 performance_schema_max_table_instances=400 5 table_definition_cache=400 6 table_open_cache=256 7 # 修改 8 sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION 9 10 [mysql] 11 default-character-set = utf8 12 13 [mysql.server] 14 default-character-set = utf8 15 16 17 [mysqld_safe] 18 default-character-set = utf8 19 20 21 [client] 22 default-character-set = utf8
重启mysql
1 # service mysqld restart
再次查看编码：
1 mysql> show variables like 'character%'; 2 +--------------------------+----------------------------+ 3 | Variable_name | Value | 4 +--------------------------+----------------------------+ 5 | character_set_client | utf8 | 6 | character_set_connection | utf8 | 7 | character_set_database | utf8 | 8 | character_set_filesystem | binary | 9 | character_set_results | utf8 | 10 | character_set_server | utf8 | 11 | character_set_system | utf8 | 12 | character_sets_dir | /usr/share/mysql/charsets/ | 13 +--------------------------+----------------------------+ 14 8 rows in set (0.00 sec)
