啊啊啊啊啊，麻烦到死，又要装mysql

不想编译了，心累，centos默认的mysql还是5.1版本的，尝试下mysql5.7吧

wget http://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm

rpm -ivh mysql57-community-release-el6-9.noarch.rpm

yum install mysql-server

顺利启动，，

设置下密码吧，啊不，初始化下安全配置

[root@cloud src]# mysql_secure_installation 

Securing the MySQL server deployment.

Enter password for user root: 
Error: Access denied for user 'root'@'localhost' (using password: NO)
[root@cloud src]# mysql -uroot -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
[root@cloud src]# 

我晕，默认密码不是空？

不知道mysql5.7的默认密码

是初始化的姿势不对吗？ 

wocao, 密码在日志里？

cat /var/log/mysqld.log|grep 'temporary password'

2016-10-16T14:57:01.551620Z 1 [Note] A temporary password is generated for root@localhost: gwKrIlyU+4O7

把密码cat出来，。。

改下密码，应该就好了吧

 # mysql_secure_installation
