Complete!
[root@localhost ~]#

2.启动docker

service docker start

[root@localhost ~]# service docker start
Redirecting to /bin/systemctl start  docker.service
[root@localhost ~]# ps -ef|grep docker
root      29129      1  0 11:25 ?        00:00:00 /usr/bin/dockerd-current --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current --default-runtime=docker-runc --exec-opt native.cgroupdriver=systemd --userland-proxy-path=/usr/libexec/docker/docker-proxy-current --selinux-enabled --log-driver=journald --signature-verification=false

root      29395   9865  0 11:27 pts/2    00:00:00 grep --color=auto docker
[root@localhost ~]#

3.加入开机启动

chkconfig docker on

从docker.io中下载centos镜像到本地 /var/lib/docker/graph

[root@localhost ~]# chkconfig docker on 
Note: Forwarding request to 'systemctl enable docker.service'.
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@localhost ~]#

4.查看已下载的镜像

docker images

[root@localhost ~]# docker images 
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
[root@localhost ~]#

5.启动一个容器

docker run -i -t centos /bin/bash

[root@localhost ~]# docker run -i -t centos /bin/bash 
Unable to find image 'centos:latest' locally
Trying to pull repository docker.io/library/centos ... 
latest: Pulling from docker.io/library/centos
d5e46245fe40: Downloading [==>                                                ] 3.244 MB/70.49 MB
^C
[root@localhost ~]#

6.查看所有容器

docker ps -a

[root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
[root@localhost ~]#

7.开启一个容器

docker start container

8.查看容器的root用户密码

docker logs <容器ID或者容器名> 2>&1 | grep '^User:' | tail -n1

9.查看容器日志

docker logs -s <容器ID或者容器名>

10.删除单个容器docker容器

docker rm loving_ride

11.删除所有容器

docker rm $(docker ps -a -q)

12.停止容docker stop 容器

docker start

13.运行一个新容器，同时为它命名、端口映射、文件夹映射。以redmine镜像为例

docker run --name redmine -p 9003:80 -p 9023:22 -d -v /var/redmine/files:/redmine/files -v/var/redmine/mysql:/var/lib/mysql sameersbn/redmine

14. 一个容器连接到另一个容器&sonar容器连接到mmysql容器，并将mmysql容器重命名为db。这样，sonar容器就可以使用db的相关的环境变量了。

run -i -t --name sonar -d -link mmysql:dbtpires/sonar-server

15. 当需要把一台机器上的镜像迁移到另一台机器的时候，需要保存镜像与加载镜像

docker save > /home/aa.tar

16.拷贝文件到另一机器

scp -r /home/aa.tar root@192.168.1.65:/home/aa.tar

17.加载打包好的镜像

docker load < /home/aa.tar

18.构建自己的镜像

docker build -t <镜像名> <镜像文件路径>

eg：docker build -t aa /home/aa.tar

解决Centos下“ssh免密码登录不生效”问题

摘要一般为了方便运维管理都会配置ssh免密登录，ssh免密登录实现也很方便。今天遇到一个完成了配置了却不能生效的问题。思考遇到这个问题一般有以下几点： authorized_keys文件是否启用 .ssh 和 authorized_keys 文件权限问题排查检查AuthorizedKeysFile配置是否启用authorized_keys root@pts/1 $ cat /etc/ssh/sshd_config |egrep AuthorizedKeysFile AuthorizedKeysFile .ssh/authorized_keys 没有问题，继续检查.ssh (700) 和 authorized_keys(644) 权限 root@pts/1 $ getfacl /root/.ssh/ getfacl: Removing leading '/' from absolute path names # file: root/.ssh/ # owner: root # group: root user::rwx group::--- other:...

CentOS安装过程注意事项

先写一些CentOS7安装中要注意的小细节，暂时没有图片提供。首先是双系统的话，Centos安装有几个点要小心：（1）linux的grub（应该是grub2）会把windows的boot程序覆盖掉，这个引导程序被覆盖了，后面的文件自然也就引导不出来了。（当时看《鸟哥linux私房菜（基础篇）》装的，结果windows的文件也就是ntfs全被洗掉了，后面才注意到鸟哥书上有提醒。。。。日常坑爹）（2）bios最好先把自己的机子的搞清楚了，我的是15年买的华硕x550ze，外装写VM590Z害我一直找不到，显卡是集成在主板上的，学期末装系统把显卡烧坏了，整个主板都换了，680还是以旧换新。华硕一般应该是F2进入bios，开机出现asus就按下去，不然开机太快还得重新来。现在又有EFI，就是EFI的进化版，怎么好用我也不知道，反正机器上有也就那样。（3）安装其实到Centos7已经很好装了，基本是傻瓜式操作，就是其他的需要注意：比如网络，一早就要把wifi或者网线接上，在那个”网络和主机名“，就是和“安装源”一起的左下角，不然后面要是出了什么错，在命令行界面里没网自己搞又搞不懂，百...
