1. 手动配置静态网卡地址不生效
2. 网卡名变成了eth1
[root@localhost network-scripts]# ls |grep ifcfg 
ifcfg-eth0 
ifcfg-lo 
[root@localhost network-scripts]# ifconfig

[root@localhost network-scripts]# vim ifcfg-eth0

手动设置静态ip地址和网关后，保存退出；然后重启网络后出现错误
[root@localhost network-scripts]# service network restart 
Shutting down loopback interface:                          [  OK  ] 
Bringing up loopback interface:                            [  OK  ] 
Bringing up interface eth0:  Error: No suitable device found: no device found for connection 'System eth0'. 
[FAILED] 
[root@localhost network-scripts]#

英汉互译
No suitable device found: no device found for connection 'System eth0'.
没有找到合适的设备：没有找到设备连接的系统eth0”。
 
总结了以下解决方案
 
更改ifconfig显示的eth1网卡名为eth0，并设置static ip地址
 
编辑/etc/udev/rules.d/70-persistent-net.rules文件，把NAME="eth0"的那行配置注释掉或者删掉，把NAME="eth1"的修改成NAME="eth0"，修改后如下：
[root@localhost network-scripts]# vim /etc/udev/rules.d/70-persistent-net.rules 
# This file was automatically generated by the /lib/udev/write_net_rules 
# program, run by the persistent-net-generator.rules rules file. 
# 
# You can modify it, as long as you keep each rule on a single 
# line, and change only the value of the NAME= key. 
# PCI device 0x8086:0x100f (e1000) 
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:52:39:18", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" 
# PCI device 0x8086:0x100f (e1000) 
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:3a:8b:02", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

查看以下信息
[root@localhost network-scripts]# ls |grep ifcfg- 
ifcfg-eth0 
ifcfg-lo 
[root@localhost network-scripts]# vim ifcfg-eth0 
DEVICE=eth0
