一、配置網(wǎng)絡(luò)
在使用Vmware Workstation10.2測(cè)試過(guò)程中，發(fā)現(xiàn)可能部分物理機(jī)100M網(wǎng)卡不能正常識(shí)別，換到了1000M網(wǎng)卡上
測(cè)試能正常識(shí)別虛擬網(wǎng)卡
Centos7系統(tǒng)的網(wǎng)卡設(shè)備命名有所變化，可參考CentOS 7下網(wǎng)絡(luò)設(shè)備命名，個(gè)人感覺(jué)既然
學(xué)習(xí)新系統(tǒng)，完全沒(méi)必要換成傳統(tǒng)的識(shí)別名方式，要勇于接受新知識(shí)~
1.通過(guò)編輯文件修改網(wǎng)絡(luò)配置
vim /etc/sysconfig/network-scripts/ifcfg-eno16777736 HWADDR=00:0c:29:14:34:51 TYPE=Ethernet BOOTPROTO=static DEFROUTE=yes PEERDNS=yes PEERROUTES=yes USERCTL=no NM_CONTROLLED=no IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eno16777736 ONBOOT=yes IPADDR=192.168.117.128 NETMASK=255.255.255.0 GATEWAY=192.168.117.2 DNS1=192.168.117.2 |
關(guān)鍵配置：
TYPE=Ethernet
BOOTPROTO=static
NAME=eno16777736
ONBOOT=yes
IPADDR=192.168.117.128
NETMASK=255.255.255.0
GATEWAY=192.168.117.2
DNS1=192.168.117.2
cat /etc/resolv.conf
nameserver 192.168.117.2
2.通過(guò)文本工具nmtui修改網(wǎng)絡(luò)配置(RHEL7/CentOS7默認(rèn)安裝,前提需要開(kāi)啟NetworkManager.service才可以使用)
yum -y install NetworkManager-tui
nmtui-edit eno16777736 修改網(wǎng)卡配置
nmtui-connect eno16777736
重啟網(wǎng)絡(luò)
systemctl restart network
systemctl status network
修改主機(jī)名：
vim /etc/hostname
centos7.simlinux.com
退出重新登錄即可生效
二、關(guān)閉不必要的服務(wù)
最小化安裝的Centos7系統(tǒng)并沒(méi)有nano、vim、wget、curl、ifconfig、lsof命令，這里首先安裝一下：
yum -y install nano vim wget curl net-tools lsof
可以通過(guò)netstat和lsof查看系統(tǒng)都運(yùn)行了哪些服務(wù)，將不必要的進(jìn)行關(guān)閉
systemctl stop postfix systemctl stop avahi-daemon systemctl disable postfix systemctl disable avahi-daemon systemctl list-unit-files 查看正在運(yùn)行服務(wù)的狀態(tài)報(bào)告 systemctl start httpd.service 啟動(dòng)服務(wù) systemctl stop httpd.service 關(guān)閉服務(wù) systemctl restart httpd.service 重啟服務(wù) systemctl reload httpd.service 重新加載服務(wù) systemctl disable httpd.service 開(kāi)機(jī)不啟動(dòng) systemctl enable httpd.service 開(kāi)機(jī)啟動(dòng) systemctl status httpd.service 查看服務(wù)運(yùn)行狀態(tài) systemctl show httpd.service 顯示服務(wù)或任務(wù)的屬性 systemctl list-dependencies httpd.service 檢查服務(wù)依賴(lài)關(guān)系 systemctl is-enabled httpd.service 檢查服務(wù)是否開(kāi)機(jī)啟動(dòng)及級(jí)別 systemctl -H 192.168.117.128 start httpd.service 啟動(dòng)192.168.117.128機(jī)器上的httpd服務(wù) |
