linux安裝docker，已經遇到的問題
阿新 • • 發佈：2019-01-14
在實際開發中，我們經常會遇到多臺機器配置相同的軟體執行環境。
比如配置一個tomcat,mysql...一些環境，其他機器也需要相同的環境時，就會一遍一遍的進行配置，比較麻煩。
而且容器和容器之間是完全隔離的。
在學習的過程中發現Docker可以解決這個問題，所以記錄下安裝遇到的坑
1、首先我們需要安裝linux系統，可以上網
2、接下來需要檢視linux核心版本，因為Docker需要Linux 3.10以上的版本
[[email protected] ~]# uname -a Linux localhost 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
3、剛裝上Linux我們更新下系統
[[email protected] ~]# yum update4、正式安裝Docker
[[email protected] ~]# yum install docker然後一直輸入y
安裝好後，檢視是否安裝成功
[[email protected] ~]# docker -v
Docker version 1.13.1, build 8633870/1.13.15、接著執行docker服務
[[email protected] ~]# service docker start Redirecting to /bin/systemctl start docker.service Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "j ournalctl -xe" for details.
我們發現啟動沒有成功，根據提示，檢視詳細內容
[[email protected] ~]# systemctl status docker.service ● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since 五 2018-10-12 13:58:56 CST; 20s ago Docs: http://docs.docker.com Process: 5179 ExecStart=/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 --i nit-path=/usr/libexec/docker/docker-init-current --seccomp-profile=/etc/docker/seccomp.json $OPTIONS $DOCKER_STORAGE_OPTIONS $ DOCKER_NETWORK_OPTIONS $ADD_REGISTRY $BLOCK_REGISTRY $INSECURE_REGISTRY $REGISTRIES (code=exited, status=1/FAILURE) Main PID: 5179 (code=exited, status=1/FAILURE) 10月 12 13:58:54 localhost systemd[1]: Starting Docker Application Container Engine... 10月 12 13:58:54 localhost dockerd-current[5179]: time="2018-10-12T13:58:54.608122086+08:00" level=warning msg="could...ound" 10月 12 13:58:54 localhost dockerd-current[5179]: time="2018-10-12T13:58:54.614454691+08:00" level=info msg="libconta...5184" 10月 12 13:58:56 localhost dockerd-current[5179]: Error starting daemon: SELinux is not supported with the overlay2 g...alse) 10月 12 13:58:56 localhost systemd[1]: docker.service: main process exited, code=exited, status=1/FAILURE 10月 12 13:58:56 localhost systemd[1]: Failed to start Docker Application Container Engine. 10月 12 13:58:56 localhost systemd[1]: Unit docker.service entered failed state. 10月 12 13:58:56 localhost systemd[1]: docker.service failed. Hint: Some lines were ellipsized, use -l to show in full.
折騰了一段時間後，在網上終於找到了解決辦法
6、找到docker-storage檔案
[[email protected] ~]# vi /etc/sysconfig/docker如下圖
我加了上圖用紅色圈住的一段程式碼
7、接著重新啟動docker,OK
[[email protected] ~]# systemctl restart docker
[[email protected] ~]# 8、比如我們要裝tomcat,輸入命令，查詢tomcat
[[email protected] ~]# docker search tomcat

[[email protected] ~]# 如果使用docker pull xxx來拉取映象，那麼會使用國外的網站，現在我們使用國內的映象來拉取，會更快的下載,如下
docker pull registry.docker-cn.com/library/xxx9、安裝tomcat到本地映象，使用pull命令
[[email protected] ~]# docker pull registry.docker-cn.com/library/tomcat

[[email protected] ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/tomcat latest 41a54fe1f79d 4 weeks ago 463 MB15、如果想使docker在Linux啟動的時候也跟著啟動，那麼輸入命令 systemctl enable docker
[[email protected] ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.16、真正的用docker執行一個tomcat映象，使用命令 docker run --name mytomcat -d tomcat:latest
[[email protected] ~]# docker run --name mytomcat -d tomcat:latest
1e05e524c6097b1dac4e58821bb220037d40488c5cf9846e37fabd29a3dfb22b17、檢視剛才執行的tomat映象，使用命令 docker ps 檢視執行中的容器
[[email protected] ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1e05e524c609 tomcat:latest "catalina.sh run" About a minute ago Up About a minute 8080/tcp mytomcat18、停止docker容器 使用命令 docker stop 容器ID或者容器名稱
[[email protected] ~]# docker stop 1e05e524c609
1e05e524c609可以使用docker ps -a 檢視容器中的映象，已經退出了。
[[email protected] ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1e05e524c609 tomcat:latest "catalina.sh run" 5 minutes ago Exited (143) 22 seconds ago mytomcat如果我們想要容器啟動，那麼我們使用docker start mytomcat命令
19、刪除容器 docker rm mytomcat
20、如果想要真正是執行tomcat可以被訪問到，那麼我們在執行docker的tomcat容器時需要加一些引數，docker run -d -p 8888:8080 tomcat 說明：-d後臺執行，-p埠對映，把主機的埠對映到容器中的埠，下面的例子是把8888對映到容器中的8080
[[email protected] ~]# docker run -d -p 8888:8080 tomcat
52f3b94d083eb9669b92e346d489df626b59377327f5d84cc3c55860fcd9614f這樣就啟動了對映，外部可以訪問啟動的容器了
[[email protected] ~]# docker ps
