一、
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)：
[mysqld]character-set-server=utf8 collation-server=utf8_general_ci [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
再次查看编码：
# mysql -uroot -pmysql> 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)
五、加入环境变量，编辑 /etc/profile，这样可以在任何地方用mysql命令
export PATH=$PATH:/usr/local/mysql//binsource /etc/profile
