centos6.8 yum安装mysql 5.6 (完整)

Posted 2020-09-25

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 -p
mysql> show variables like ‘character%‘;
