快速安装MySQL与为Lapis修改mysql字符集
快速安装MySQL
下载安装Yum源
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
安装的MySQL与服务器端
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
启动关闭 MySQL服务
systemctl start mysqld.service
systemctl status mysqld.service
修改root密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';
grant all on *.* to root@'%' identified by 'password';
修改mysql字符集
第一种方式:
show variables like '%char%';
set character_set_connection=gbk;
set character_set_client=gbk;
set character_set_results=gbk;
这种情况,在Mysql重新起动之后,值还会恢复到原先值。
第二种方式:
my.ini
[mysqld]
#default-character-set = utf8
init-connect='SET NAMES utf8'
character-set-server = utf8
[mysql]
default-character-set = utf8
SET NAMES utf8
它相当于下面的三句指令:
SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;
这种方式在Mysql得起之后,会安装my.ini中的设置重新设定。
特别是Lapis框架,要从中文数据库中取数据,必须设置中文字符集。
