操作系统版本CentOs6.4，mysql版本Mysql5.1

1、开机启动，Secure CRT连接虚拟机，连接失败。解决办法：http://blog.csdn.net/jianglei421/article/details/6362928

#rpm -qa |grep ssh 检查是否装了SSH包
#chkconfig --list sshd 检查SSHD是否在本运行级别下设置为开机启动
#chkconfig --level 2345 sshd on  如果没设置启动就设置下.
#service sshd restart  重新启动
#netstat -antp |grep sshd  看是否启动了22端口.确认下.
#iptables -nL  看看是否放行了22口.
#setup---->防火墙设置   如果没放行就设置放行.
