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

service mysqld start
# service mysqld start 初始化 MySQL 数据库： [确定] Installing validate password plugin: [确定] 正在启动 mysqld： [确定]
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
