关闭selinux(万恶之源)：
临时生效：setenforce 0
永久生效：修改/etc/selinux/config文件中设置SELINUX=disabled
配置网路：
vi /etc/sysconfig/network-scripts/ifcfg-eth0
service network restart
关闭network manage
临时生效：service NetworkManager stop
永久生效：chkconfig NetworkManager off
DEVICE="eth0"
BOOTPROTO=static #静态分配ip
IPADDR=192.168.1.201 #ip
GATEWAY=192.168.1.1 #网关
NETMASK=255.255.255.0 #子网掩码
HWADDR="00:0C:29:79:F5:AF"

TYPE="Ethernet"
UUID="493298e6-6dc4-4e70-a0e3-05d24a31c53f"
DNS1=192.168.1.1 #主dns
使用eth1：
cat /etc/udev/rules.d/70-persistent-net.rules 记录eth1的mac地址
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0" 改成 DEVICE="eth1" ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
# service network restart
优化ssh连接速度：
vi /etc/ssh/ssh_config 和 vi /etc/ssh/sshd_config ,设置GSSAPIAuthentication no ,UseDNS=no并重启：service sshd restart 或 etc/init.d/sshd restart
永久关闭防火墙:
chkconfig iptables off
设置时区：
1设置Centos时区：tzselect 然后依次输入 5 回车 9 回车 1 回车 1回车
2替换系统时区文件：cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
