起因：
1.208这台机器用来做测试的zabbix环境，一直没有关过机，由于电脑开的东西比较多，有些卡慢，于是昨天下班的时候把虚拟机挂起，电脑关机了，今天早上来的时候打开虚拟机发现网卡起不来了，不能远程连接，于是登陆机器进行检查；
现象：
[root@Zabbix server ~]# /etc/init.d/network restart
1 /etc/sysconfig/network: line 2: server: command not found 2 /etc/sysconfig/network: line 2: server: command not found 3 Shutting down interface eth0: ../network: line 2: server: command not found 4 ../network: line 2: server: command not found 5 /etc/sysconfig/network: line 2: server: command not found 6 /etc/sysconfig/network: line 2: server: command not found 7 /etc/sysconfig/network: line 2: server: command not found 8 /etc/sysconfig/network: line 2: server: command not found 9 /etc/sysconfig/network: line 2: server: command not found 10 [ OK ] 11 Shutting down loopback interface: ../network: line 2: server: command not found 12 ../network: line 2: server: command not found 13 /etc/sysconfig/network: line 2: server: command not found 14 /etc/sysconfig/network: line 2: server: command not found 15 /etc/sysconfig/network: line 2: server: command not found 16 /etc/sysconfig/network: line 2: server: command not found 17 [ OK ] 18 /etc/sysconfig/network: line 2: server: command not found 19 /etc/sysconfig/network: line 2: server: command not found 20 /etc/sysconfig/network: line 2: server: command not found 21 Bringing up loopback interface: ../network: line 2: server: command not found 22 ../network: line 2: server: command not found 23 /etc/sysconfig/network: line 2: server: command not found 24 ../network: line 2: server: command not found 25 /etc/sysconfig/network: line 2: server: command not found 26 [ OK ] 27 Bringing up interface eth0: ../network: line 2: server: command not found 28 ../network: line 2: server: command not found 29 30 Determining IP information for eth0.../etc/sysconfig/network: line 2: server: command not found 31 /etc/sysconfig/network: line 2: server: command not found 32 Cannot find device "server" 33 failed. 34 [FAILED] 35 /etc/sysconfig/network: line 2: server: command not found
分析：
启动报错提示Determining IP information for eth0.../etc/sysconfig/network: line 2: server: command not found
/etc/sysconfig/network: line 2: server: command not found （之前疏忽看成是/etc/init.d/network文件有问题，从别的机器下载了一份配置文件通过diff对比没发现什么不通，还检查了network下所有文件的完整性，很尴尬...）
解决：
[root@Zabbix server ~]# vim /etc/sysconfig/network
1 NETWORKING=yes 2 HOSTNAME=Zabbix server （发现这里主机名Zabbix server这中间有一个空格，不符合规范，所以启动的时候不能识别）
把空格删除，重新启动 （成功）
[root@Zabbix server ~]# /etc/init.d/network restart
1 Shutting down interface eth0: [ OK ] 2 Shutting down loopback interface: [ OK ] 3 Bringing up loopback interface: [ OK ] 4 Bringing up interface eth0: 5 Determining IP information for eth0... done. 6 [ OK ]
