一、检查系统是否安装老版本,有的话干掉
#yum list installed | grep mysql
mysql-libs.x86_64 5.1.73-5.el6_6 @anaconda-CentOS-201508042137.x86_64/6.7 #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(网络原因,下载时间过长,这是唯一的缺点,如果机房网络环境好可以这样装)
# yum install mysql -y
三、设置远程root
1.启动mysql和设置密码、登录
# service mysqld start
# mysql_secure_installation
# mysql -uroot -p 
2.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原来编码:
mysql> show variables like ‘character%‘;
设置编码
# vi /etc/my.cnf
如下(少补):

# 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

再次查看编码:

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

完成yum方式安装。

总结:如果网络下载速度快,可以用这种方式

 

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]

# 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]
