前言

一台新开的云主机，我们往往需要对其进行初始化，或加入一些简单的调优参数，以适应测试或生产的基本需求

这里简要分享一下Linux初始化的检查列表，以帮忙更为高效地进行检查确认

概要

环境

这里以一台Centos6的服务器进行演示

[root@localhost ~]# uname -a 
Linux localhost.localdomain 2.6.32-573.el6.x86_64 #1 SMP Thu Jul 23 15:44:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# lsb_release

[root@localhost ~]# cat /etc/issue

网络

网络是最先要解决的问题

外网联通

首先要配通网络，以使其可以获得各种网络资源

• IPADDR/NETMASK
• GATEWAY
• DNS

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1 
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
