昨天由于失误导致服务器启动不了了，已经将卷组挂载上去，挂载到原来的目录/home下
应用服务器上主要是weblogic，主要把weblogic启动就好
step1:创建weblogic的启动用户wls.
problem1:在本地cmd的时候ping不通服务器地址，但是在其它服务器上可以通过ssh来连接，说明路由配置有问题。
我本地网段为172.20.61.网段，服务器是172.20.63. 网段。
重新配置路由表。修改/etc/sysconfig/static-routes
添加以下路由：

any net 172.20.11.0/24 gw 172.20.63.254
any net 172.20.29.0/24 gw 172.20.63.254
any net 172.20.50.0/24 gw 172.20.63.254
any net 172.20.51.0/24 gw 172.20.63.254
any net 172.20.60.0/24 gw 172.20.63.254
any net 172.20.61.0/24 gw 172.20.63.254
any net 180.166.105.84 netmask 255.255.255.255 gw 172.20.63.254

problem2:启动weblogic的时候海报了一个错误：

<Server subsystem failed. Reason: java.lang.AssertionError: Could not obtain the localhost address. The most likely cause is an error in the network configuration of this machine.

        Truncated. see log file for complete stacktrace
java.net.UnknownHostException: bogon: bogon
        at java.net.InetAddress.getLocalHost(InetAddress.java:1354)

解决办法是修改/etc/hosts文件
配置主机名
127.0.0.1 app1

problem3:当把服务启动好之后，端口也启动好了，但是发现无法访问，后经排查是防火墙的问题：
关闭防火墙：

service iptables stop

至此，服务器恢复正常。
