精簡版centos6.5安裝mysql5.7直至遠程登錄成功

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

yum repolist all | grep mysql

 yum install mysql-community-server

service mysqld start

搜索默認初始密碼

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

2016-11-26T16:01:37.738626Z 1 [Note] A temporary password is generated for root@localhost: M4ym/:3h72mx
[root@bogon ~]# mysql -uroot -pM4ym/:3h72mx

用默認密碼登錄

mysql -uroot -pM4ym/:3h72mx

登錄後修改密碼

 ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

賦權遠程登錄

use mysql;

update user set host = '%'  where user ='root';

ip設置： eth0裏設置爲dhcp, 不要複製eh0爲eth1去改，否則要修改/etc/udev/rules.d/70-persistent-net.rules。(較新的穩定版本如centos7.2不需要修改)

BOOTPROTO=dhcp  啓動網絡還不生效則重啓虛機

另外一臺機器登錄，報10060，根據【1】

開放3306端口

  /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT;

 /etc/init.d/iptables save;
重啓防火牆:

service iptables stop;

service iptables start;

再次登錄，ok
