3. 修改tmp文件权限
[root@slave2 home]# chmod 777 /tmp/
4.启动mysql Service
[root@slave2 home]# service mysqld start
Starting mysqld: [ OK ]
5.初始化mysql
[root@slave2 home]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
此错误通过（https://jingyan.baidu.com/article/636f38bb21d883d6b946106f.html）方法解决：
停掉MySQL服务：
/etc/init.d/mysqld stop
使用safe模式，进行重启：
mysqld_safe --skip-grant-tables
使用root账户，无密码登录：
mysql -u root
选择mysql database:
use mysql;
为root用户更改密码为： 123（自行设定）：
update user set password=PASSWORD("123") where User = 'root';
