NETWORKING=yesHOSTNAME=gpdb

步骤二、运行hostname gpdb命令

步骤三、运行vi /etc/hosts命令192.168.1.121 gpdb # Added by NetworkManager127.0.0.1 localhost.localdomain localhost::1 gpdb localhost6.localdomain6 localhost6

步骤四、运行reboot命令重新启动电脑后或者使用service network restart命令重新启动网络服务后生效

修改前的/etc/sysconfig/network文件默认内容为NETWORKING=yesHOSTNAME=bogon

修改前下的/etc/hosts文件默认内容为192.168.1.121 bogon # Added by NetworkManager127.0.0.1 localhost.localdomain localhost::1 bogon localhost6.localdomain6 localhost6
