2.mysql 安装

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

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
# chkconfig --list | grep mysqld
# chkconfig mysqld on

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;

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
