Mysql的安全设置
CentOS上的root默认密码可以在文件/var/log/mysqld.log找到，通过下面命令可以打印出来
cat /var/log/mysqld.log | grep -i 'temporary password'
执行下面命令进行安全设置，这个命令会进行设置root密码设置，移除匿名用户，禁止root用户远程连接等
`mysql_secure_installation`
设置数据库编码为utf8
打开配置文件
` vim /etc/my.cnf`
在[mysqld]，[client]，[mysql]节点下添加编码设置
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
collation-server = utf8_unicode_ci
init-connect='SET NAMES utf8'
character-set-server = utf8
重启Mysql即可
` systemctl restart mysqld`
