whereis mysql //查看安装目录，分别删除

4、初始化mysql

#查看是否开机启动
chkconfig --list | grep mysqld
#设为开机启动
chkconfig mysqld on
#启动mysql进行初始化
service mysqld start
#查看密码
grep "password" /var/log/mysqld.log
#进入mysql
mysql -uroot -p密码
#修改密码
set password for ‘root‘@‘localhost‘ = password(‘新密码‘);

5、修改mysql字符集为UTF-8：

vim /etc/my.cnf; 
在[mysqld]部分添加：character-set-server=utf8;
在文件末尾新增[client]段，并在[client]段添加：default-character-set=utf8
