Ubuntu 与 Centos常见使用区别

以前是搞Centos的，无赖现公司生产环境使用的是Ubuntu，记录下常见使用情况下的一些不同点.....：

• 软件安装管理：

Centos使用yum install，Ubuntu使用apt-get install

Centos搜索已安装软件使用rpm -q,Ubuntu使用apt-cache search 

Ubuntu默认文本编辑器为nano，使用系统管理工具可修改默认编辑器update-alternatives --config editor

• 网卡配置文件：

Centos网卡配置文件目录在/etc/sysconfig/network-scripts/网卡名

Ubuntu网卡配置文件目录在/etc/network/interfaces

配置示例：

Centos

TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens33 UUID=9936589f-50ac-4e23-b64a-a8a31abfdd91 DEVICE=ens33 ONBOOT=yes IPADDR=192.168.254.129 PREFIX=255.255.255.0 GATEWAY=192.168.254.2 ZONE=

Ubuntu（重启网络服务sudo systemctl restart networking）

• Ubuntu使用国内163源：

以下部分加入/etc/apt/source.list文件最前端，注意备份。
