关于如何使用docker部署centos系统测试环境
作者：江湖有缘
这篇文章主要介绍了关于如何使用docker部署centos系统测试环境，Docker属于操作系统虚拟化技术,本文图文讲解部署过程,需要的朋友可以参考下
一、检查本地服务器系统版本
[root@node ~]# cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"
[root@node ~]# cat /etc/centos-release CentOS Linux release 7.6.1810 (Core)
二、检查docker版本
[root@node ~]# docker version Client: Docker Engine - Community Version: 20.10.17 API version: 1.41 Go version: go1.17.11 Git commit: 100c701 Built: Mon Jun 6 23:05:12 2022 OS/Arch: linux/amd64 Context: default Experimental: true Server: Docker Engine - Community Engine: Version: 20.10.17 API version: 1.41 (minimum version 1.12) Go version: go1.17.11 Git commit: a89b842 Built: Mon Jun 6 23:03:33 2022 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.6.6 GitCommit: 10c12954828e7c7c9b6e0ea9b0c02b01407d3ae1 runc: Version: 1.1.2 GitCommit: v1.1.2-0-ga916309 docker-init: Version: 0.19.0 GitCommit: de40ad0
三、检查docker状态
[root@node ~]# systemctl status docker
● docker.service - Docker Application Container Engine

Hint: Some lines were ellipsized, use -l to show in full.
四、下载centos镜像
[root@node ~]# docker pull centos:7 7: Pulling from library/centos Digest: sha256:9d4bcbbb213dfd745b58be38b13b996ebb5ac315fe75711bd618426a630e0987 Status: Image is up to date for centos:7 docker.io/library/centos:7
五、创建centos容器
1.运行cnentos容器
[root@node ~]# docker run -it --name centos_test centos:7 /bin/bash [root@db4f4dfa3a84 /]#
2.进入容器内
[root@node ~]# docker run -it --name centos_test centos:7 /bin/bash [root@db4f4dfa3a84 /]# ls anaconda-post.log bin dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var [root@db4f4dfa3a84 /]# pwd /
六、centos容器内部测试
1.安装ifconfig命令的软件包
[root@db4f4dfa3a84 /]# yum -y install net-tools Loaded plugins: fastestmirror, ovl Loading mirror speeds from cached hostfile * base: mirrors.huaweicloud.com * extras: mirrors.ustc.edu.cn * updates: mirrors.ustc.edu.cn Resolving Dependencies --> Running transaction check ---> Package net-tools.x86_64 0:2.0-0.25.20131004git.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================================================================================== Package Arch Version Repository Size =================================================================================================================================================== Installing: net-tools x86_64 2.0-0.25.20131004git.el7 base 306 k Transaction Summary =================================================================================================================================================== Install 1 Package Total download size: 306 k Installed size: 917 k Downloading packages: net-tools-2.0-0.25.20131004git.el7.x86_64.rpm | 306 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : net-tools-2.0-0.25.20131004git.el7.x86_64 1/1 Verifying : net-tools-2.0-0.25.20131004git.el7.x86_64 1/1 Installed: net-tools.x86_64 0:2.0-0.25.20131004git.el7 Complete!
2.查看容器内IP地址
[root@db4f4dfa3a84 /]# ifconfigeth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 172.17.0.6 netmask 255.255.0.0 broadcast 172.17.255.255 ether 02:42:ac:11:00:06 txqueuelen 0 (Ethernet) RX packets 7037 bytes 25618849 (24.4 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 4655 bytes 269171 (262.8 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 loop txqueuelen 1000 (Local Loopback) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0[root@db4f4dfa3a84 /]# ifconfig

3.测试与宿主机网络连通情况
[root@db4f4dfa3a84 /]# ping 192.168.3.166 -c 6 PING 192.168.3.166 (192.168.3.166) 56(84) bytes of data. 64 bytes from 192.168.3.166: icmp_seq=1 ttl=64 time=0.091 ms 64 bytes from 192.168.3.166: icmp_seq=2 ttl=64 time=0.130 ms 64 bytes from 192.168.3.166: icmp_seq=3 ttl=64 time=0.104 ms 64 bytes from 192.168.3.166: icmp_seq=4 ttl=64 time=0.109 ms 64 bytes from 192.168.3.166: icmp_seq=5 ttl=64 time=0.075 ms 64 bytes from 192.168.3.166: icmp_seq=6 ttl=64 time=0.092 ms --- 192.168.3.166 ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5010ms rtt min/avg/max/mdev = 0.075/0.100/0.130/0.018 ms
4.让centos容器后台运行
从容器退出，但不停止容器: Ctrl+P+Q
[root@node ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES db4f4dfa3a84 centos:7 "/bin/bash" 11 minutes ago Up 11 minutes centos_test
