Centos6.X 安装mysql5.6
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密码及相应配置
mysql_secure_installation此命令会执行如下几个操作：
a)为root用户设置密码
b)删除匿名账号
c)取消root用户远程登录
d)删除test库和对test库的访问权限
e)刷新授权表使修改生效
登陆root账号
mysql -uroot -p 建立远程root用户
mysql> use mysql;
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)：
character-set-server=utf8
collation-server=utf8_general_ci
sql_mode='NO_ENGINE_SUBSTITUTION'
default-character-set = utf8
default-character-set = utf8
default-character-set = utf8
default-character-set = utf8重启mysql
service mysqld restart再次查看编码：
# mysql -uroot -p
mysql> show variables like 'character%';
