centos7开启网卡功能

https://blog.csdn.net/nkd50000/article/details/78903479

网卡默认是关闭的,未分配ip地址,解决办法:
1、修改文件 vim  /etc/sysconfig/network-scripts/ifcfg-enp1s0

TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp1s0
UUID=b95a3321-61d6--b648-16c6ec073738
DEVICE=enp1s0
ONBOOT=no

2、找到内容 ONBOOT=no ,需要修改为ONBOOT=yes然后保存退出。
3、service network restart #重启网络服务

CentOS7.2 创建本地YUM源和局域网YUM源

https://www.cnblogs.com/nidey/p/6200685.html


[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core)
[root@localhost ~]# mount -t iso9660 /opt/soft/CentOS-7-x86_64-DVD-1611.iso /mnt/CentOS7/
[root@localhost ~]# mount -t auto /opt/soft/CentOS-7-x86_64-DVD-1611.iso /mnt/CentOS7/
[root@localhost ~]# pwd /etc/yum.repos.d
创建yum repo文件如下
[root@localhost ~]# more lindows.repo
[lindows.iteye.com]
name=local
baseurl=file:///mnt/CentOS7
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

OS + CentOS 7.3.1611 / docker 安装

第一步, 配置yum docker更新源

文件:/etc/yum.repos.d/CentOS7_15090385.repo

docker 自建仓库

1、有台ubuntu 14.10.4 LTS 已经安装了docker registry

vagrant@vagrant-ubuntu-trusty-64:~$ ps -ef | grep reg
root 1856 1 0 Oct30 ? 00:13:14 /usr/bin/docker -d --insecure-registry 10.24.41.95:5000

2、有台CentOS 7.3 只安装了docker 软件,yum install *docker*

新增文件:

[root@SCTS-PC-DEV docker]# vim /etc/docker/daemon.json

文件内容:

{
"insecure-registries":["10.24.41.103:5000"]
}

启动docker 仓库

[root@SCTS-PC-DEV docker]# /bin/systemctl restart  docker.service

[root@SCTS-PC-DEV docker]# docker pull registry

[root@SCTS-PC-DEV docker]#  docker run -d -p 5000:5000 -v /data/soft/registry:/tmp/registry 10.24.41.95:5000/registry:latest

[root@SCTS-PC-DEV docker]# docker ps -a

docker验证:
http://10.27.188.103:5000/v2/_catalog 返回 {"repositories":[]}
http://10.27.188.103:5000/v1/repositories/mystf/stf/images

查看images
docker images

docker push 10.27.188.110:5000/mystf/stf 提交镜像

centos 7.3 下挂载ISO文件,让开启自启动挂载

参考:CentOS 7添加开机启动服务/脚本

http://www.linuxidc.com/Linux/2016-12/138079.htm

 一、添加开机自启服务
在CentOS 7中添加开机自启服务非常方便,只需要两条命令(以Jenkins为例):
systemctl enable jenkins.service #设置jenkins服务为自启动服务
sysstemctl start jenkins.service #启动jenkins服务
二、添加开机自启脚本
在centos7中增加脚本有两种常用的方法,以脚本autostart.sh为例:
#!/bin/bash
#description:开机自启脚本
/usr/local/tomcat/bin/startup.sh #启动tomcat
方法一
、赋予脚本可执行权限(/opt/script/autostart.sh是你的脚本路径)
chmod +x /opt/script/autostart.sh
、打开/etc/rc.d/rc/local文件,在末尾增加如下内容
/opt/script/autostart.sh
、在centos7中,/etc/rc.d/rc.local的权限被降低了,所以需要执行如下命令赋予其可执行权限
chmod +x /etc/rc.d/rc.local
方法二
、将脚本移动到/etc/rc.d/init.d目录下
mv /opt/script/autostart.sh /etc/rc.d/init.d
、增加脚本的可执行权限
chmod +x /etc/rc.d/init.d/autostart.sh
、添加脚本到开机自动启动项目中
cd /etc/rc.d/init.d
chkconfig --add autostart.sh
chkconfig autostart.sh on
以上两种方法均已在centos7系统上验证过,

[root@CNHS-SCTS-APP06 ~]# mkdir -p /mnt/CentOS73

[root@CNHS-SCTS-APP06 ~]# chmod +x /etc/rc.d/rc.local

修改文件:/etc/rc.d/rc.local

新增内容:

sudo mount -t iso9660 -o loop /opt/soft/CentOS-7-x86_64-DVD-1611.iso /mnt/CentOS73/

[root@CNHS-SCTS-APP06 ~]# reboot

centos 7.3 下挂载U盘和移动硬盘
http://blog.csdn.net/u010048823/article/details/51306175
linux如何挂载U盘
http://jingyan.baidu.com/article/f0062228dc2aa6fbd3f0c8ec.html

1、向CentOS机器插入U盘 ,检查U盘文件类型Fat32 、exFat、NTFS还是其他。
[root@CNHS-SCTS-APP06 ~]# fdisk -l
Disk /dev/sda: 31.7 GB, 31675383808 bytes, 61865984 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000ace03
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 2099199 1048576 83 Linux
/dev/sda2 2099200 61865983 29883392 8e Linux LVM
Disk /dev/mapper/cl-root: 27.4 GB, 27426553856 bytes, 53567488 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/mapper/cl-swap: 3166 MB, 3166699520 bytes, 6184960 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/sdb: 15.6 GB, 15552479232 bytes, 30375936 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0xcad4ebea
Device Boot Start End Blocks Id System
/dev/sdb4 * 256 30375935 15187840 c W95 FAT32 (LBA)

2、查看U盘文件类型是Fat32 、exFat、NTFS还是其他。

本次U盘类型为FAT32:       /dev/sdb4 * 256 30375935 15187840 c W95 FAT32 (LBA)

3、创建/mnt/u_disk 挂载目录,准备给U盘挂载
[root@CNHS-SCTS-APP06 ~]# mkdir -p /mnt/u_disk

3、创建/mnt/u_disk 挂载目录,开始给U盘挂载,挂载ok!
[root@CNHS-SCTS-APP06 ~]# mount -t vfat /dev/sdb4 /mnt/u_disk

4、若是NTFS 文件的u盘则如下挂载方法

4.1、先安装CentOS7.3 系统 支持NTFS 文件类型

[root@CNHS-SCTS-APP06 ~]# yum list *ntfs* 

[root@localhost udisk]# yum list *ntfs*
已加载插件:fastestmirror, langpacks, priorities
Loading mirror speeds from cached hostfile
……

可安装的软件包
findntfs.x86_64 1.3-1.el7.rf rpmforge
fuse-ntfs-3g.x86_64 2013.1.13-2.el7.rf rpmforge
fuse-ntfs-3g-devel.x86_64 2013.1.13-2.el7.rf rpmforge
ntfs-3g.x86_64 2:2016.2.22-1.el7 epel
ntfs-3g-devel.x86_64 2:2016.2.22-1.el7 epel
ntfsprogs.x86_64 2:2016.2.22-1.el7 epel

[root@CNHS-SCTS-APP06 ~]# yum install fuse-ntfs-3g 

4.2、再挂载U盘

[root@CNHS-SCTS-APP06 ~]#  mount -t ntfs-3g /dev/sdb4 /mnt/u_disk

CentOS 7.0关闭默认防火墙启用iptables防火墙

http://www.linuxidc.com/Linux/2015-05/117473.htm

CentOS 7.0默认使用的是firewall作为防火墙,这里改为iptables防火墙步骤。

1、关闭firewall:
[root@cnhq-scts-app28 ~]# systemctl stop firewalld.service #停止firewall
[root@cnhq-scts-app28 ~]# systemctl disable firewalld.service #禁止firewall开机启动
[root@cnhq-scts-app28 ~]# firewall-cmd --state #查看默认防火墙状态(关闭后显示notrunning,开启后显示running)

- 获得root 控制权限。在“#”下操作。
- 查看防火墙状态。
systemctl status firewalld
- 临时关闭防火墙命令。重启电脑后,防火墙自动起来。
systemctl stop firewalld
- 永久关闭防火墙命令。重启后,防火墙不会自动启动。
systemctl disable firewalld
- 打开防火墙命令。
systemctl enable firewalld

CentOS 7.0 网卡配置及重命名教程

http://www.linuxidc.com/Linux/2017-05/143287.htm

  1. 第一步,查询本地路由表信息
  2. [root@SCTS-PC-DEV rc.d]# route
  3. Kernel IP routing table
  4. Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
  5. 10.19.252.84    10.24.41.254    255.255.255.255 UGH   100    0        0 enp3s0
  6. 10.24.41.0      0.0.0.0         255.255.255.0   U     100    0        0 enp3s0
  7. 192.168.122.0   0.0.0.0         255.255.255.0   U     0      0        0 virbr0
  8. 第二步,添加默认网关,就好了。
  9. [root@SCTS-PC-DEV rc.d]# route add default gw 10.24.41.254
  10. [root@SCTS-PC-DEV rc.d]# route
  11. Kernel IP routing table
  12. Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
  13. default         gateway         0.0.0.0         UG    0      0        0 enp3s0
  14. 10.19.252.84    gateway         255.255.255.255 UGH   100    0        0 enp3s0
  15. 10.24.41.0      0.0.0.0         255.255.255.0   U     100    0        0 enp3s0
  16. 192.168.122.0   0.0.0.0         255.255.255.0   U     0      0        0 virbr0
  17. 第三步,能ping通外部IP地址和域名地址了
  18. [root@SCTS-PC-DEV rc.d]# ping 192.168.118.201
  19. PING 192.168.118.201 (192.168.118.201) 56(84) bytes of data.
  20. 64 bytes from 192.168.118.201: icmp_seq=1 ttl=55 time=1.55 ms
  21. 64 bytes from 192.168.118.201: icmp_seq=2 ttl=55 time=1.56 ms
  22. 64 bytes from 192.168.118.201: icmp_seq=3 ttl=55 time=1.68 ms

配置永久生效方法如下:

  1. 查看已配置的默认网关地址
  2. [root@SCTS-PC-DEV ~]# more /etc/sysconfig/network-scripts/ifcfg-enp3s0  | grep GATEWAY
  3. GATEWAY0=10.24.41.254
  4. [root@SCTS-PC-DEV ~]# nmcli connection show enp3s0 | grep GATEWAY
  5. IP4.GATEWAY:                            10.24.41.254
  6. IP6.GATEWAY:

CentOS 6/7网卡重启命令回顾:

CentOS 6 以下用:service network restart

CentOS 7 以上用:systemctl restart network.service

CentOS 7查看网卡:systemctl status network.service 或 service network status

  1. [root@SCTS-PC-DEV ~]# more /etc/sysconfig/network-scripts/ifcfg-enp3s0
  2. TYPE=Ethernet
  3. BOOTPROTO=dhcp
  4. DEFROUTE=yes
  5. IPV4_FAILURE_FATAL=yes
  6. IPV6INIT=no
  7. IPV6_AUTOCONF=yes
  8. IPV6_DEFROUTE=yes

  13. DEVICE=enp3s0    #物理网卡名称
  14. ONBOOT=yes  #开启自动启用网络连接设置开机启动
  15. GATEWAY0=10.24.41.254  #设置默认网关
  16. IPV6_PEERDNS=yes
  17. IPV6_PEERROUTES=yes
  18. PEERDNS=yes
  19. DNS1=202.102.152.3 #设置主DNS
  20. DNS2=202.102.128.68   #设置备DNS
  21. PEERROUTES=yes

 案例三:centos下问题:connect:network is unreachable / 静态分配地址解决方法

http://www.cnblogs.com/valu/p/6515991.html

  1. 问题描述
  2.   弄了三台机器准备搭建一个集群,按照centos7系统,一台主节点安装桌面环境,两台计算节点。配置计算节点的时候,发现ping不通,出现connect:network is unreachable问题。   
  3. 问题分析
  4.   /etc/sysconfig/network-scripts/中只有ifcfg-lo文件,缺少ifcfg-eth0。
  5. 解决方案
  6. 方案一(临时)
  7.   使用命令ifconfig eth0 192.168.1.x可以正常设置eth0的IP,该方法仅为临时处理办法,系统重启后即失效了。
  8. 方案二(永久)
  9. 第一步:
  10. vim /etc/sysconfig/network-scripts/ifcfg-eth0
  11. 第二步,编辑:
  12. DEVICE=eth0 # 物理设备名称
  13. IPADDR=192.168.1.x #IP地址,需要设置
  14. NETMASK=255.255.255.0 #子网掩码
  15. GATEWAY=192.168.1.1 # 网关地址
  16. ONBOOT=yes #激活设备
  17. USERCTL=no #非ROOT用户不可以控制该设备
  18. BOOTPROTO=[none|static|bootp|dhcp]
  19. #引导时不使用协议|静态分配|BOOTP协议|dhcp协议,这里我选用的是静态分配,static。
  20. HWADDR=00:13:D3:27:9F:80 #MAC地址,通过ifconfig或者ip a获得
  21. NAME=eth0 #名称
  22. 第三步在文件/etc/rc.d/rc.local最后加入ifup eth0(/etc/rc.local脚本是在所有其它初始化脚本执行完毕后执行)。
  23. 第四步,reboot,重启电脑.

案例四:Centos7添加静态路由

http://www.cnblogs.com/panblack/p/Centos7_Static_Routes.html

二、  部署 libgconf-2.so.4文件动态库文件执行

解决过程:

(共62个安装包,是否不合理安装,未知,需要开发确认哪些必备基础依赖软件)

[root@CNHQ-SCTS-APP03 ~]# yum install gconf*

[root@CNHQ-SCTS-APP03 ~]# scp -r root@10.24.41.139:/usr/lib64/libgconf-2.so.4.1.5 /usr/lib64/

[root@CNHQ-SCTS-APP03 ~]# chmod 777 /usr/lib64/libgconf-2.so.4.1.5

[root@CNHQ-SCTS-APP03 ~]# whereis libgconf-2.so.4

libgconf-2.so: /usr/lib64/libgconf-2.so.4

[root@CNHQ-SCTS-APP03 ~]# reboot

执行成功如下:

[root@CNHQ-SCTS-APP03 ~]# /home/test/Downloads/TR_jdk1.8_Linux_prd180413/lib/autodependency/mobile/appium/node_modules/appium-chromedriver/chromedriver/linux/chromedriver_64

发现docker先人可能研究过,拷贝libc++.so到操作系统/usr/lib64/libc++.so重启使生效,appt命令可以执行了。如下:

[root@CNHQ-SCTS-APP03 android-4.4.2]cp /home/test/Downloads/TR_jdk1.8_Linux_prd180413/lib/autodependency/mobile/android_sdk/platform-tools/lib64/libc++.so /usr/lib64/libc++.so

执行成功如下:

[root@CNHQ-SCTS-APP03 android-4.4.2]# /home/test/Downloads/TR_jdk1.8_Linux_prd180413/lib/autodependency/mobile/android_sdk/build-tools/android-4.4.2/aapt

Android Asset Packaging Tool

Usage:

aapt l[ist] [-v] [-a] file.{zip,jar,apk}

List contents of Zip-compatible archive

四、  配置/android_sdk环境变量

先在Downloads目录拷贝一份android_sdk文件

vim /etc/profil

export ANDROID_HOME=/home/test/Downloads/android_sdk

export PATH=$ANDROID_HOME/build-tools:$PATH

source /etc/profile

end
