2.mysql 安装

• [code]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

• [code]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

• [code]安装MYSQL数据库
  # yum install mysql-community-server -y

• [code]设置为开机启动
  # chkconfig --list | grep mysqld
  # chkconfig mysqld on

• [code]设置远程root
  mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你设置的密码' WITH GRANT OPTION;
  mysql> flush privileges;

• [code]设置utf-8编码
  
  查看原有编码：
  mysql> show variables like 'character%';
  
  查看命令
  # vi /etc/my.cnf
  ===========================================================
  [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
  ====================================================================
  
  重启mysql
  # service mysqld restart

• 设置登录用户，# vi /etc/my.cnf 在[mysqld]中添加 skip-grand-tables, 登录mysql，update user set password=password("root") where user='root', 之后quit mysql。在[mysqld]中注释skip-grand-tables，重启mysql则命令为：/etc/init.d/mysqld restart
