centos yum方式安装mysql （完整记录）

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> 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]
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

再次查看编码：

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