初始化信息参考:
创建用户：
useradd mysql
mkdir -p /data/mysql/data
mkdir -p /logs/mysql/
chown mysql:mysql -R /data/mysql/data
chown mysql:mysql -R /logs/mysql
yum -y install libaio
初始化数据库：
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data
cat /logs/mysql/mysql-error.log|grep password|awk '{print $NF}'
修改密码：
alter user root@'localhost' identified by "password";
配置文件自动生成参考信息：
在线cnf 文件生产工具 http://imysql.com/my-cnf-wizard.html
