卸载旧

Docker 的较旧版本被调用或 。如果安装了这些组件,请卸载它们以及关联的依赖项。docker``docker-engine
$ sudo yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-engine

使用存储库🔗

在首次安装 Docker 引擎之前,您需要设置 Docker 存储库。之后,可以从存储库安装和更新 Docker。

设置存储库

安装包(提供实用程序)并设置稳定的存储库。yum-utils``yum-config-manager
$ sudo yum install -y yum-utils #这个使用的时国外的镜像 $ sudo yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo #阿里云 sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://q6xxwzgk.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker
安装最新版本的Docker 引擎和容器,或转到下一步以安装特定版本:
#先更新 yum $ sudo yum makecache fast # docker-ce社区版 ee企业版 $ sudo yum install docker-ce docker-ce-cli containerd.io
启动 Docker。
$ sudo systemctl start docker #使用docker version 查看 $ sudo # docker version Client: Docker Engine - Community Version: 20.10.3 API version: 1.41 Go version: go1.13.15 Git commit: 48d30b5 Built: Fri Jan 29 14:34:14 2021 OS/Arch: linux/amd64 Context: default Experimental: true Server: Docker Engine - Community Engine: Version: 20.10.3 API version: 1.41 (minimum version 1.12) Go version: go1.13.15 Git commit: 46229ca Built: Fri Jan 29 14:32:37 2021 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.4.3 GitCommit: 269548fa27e0089a8b8278fc4fc781d7f65a939b runc: Version: 1.0.0-rc92 GitCommit: ff819c7e9184c13b7c2607fe6c30ae19403a7aff docker-init: Version: 0.19.0 GitCommit: de40ad0
通过运行映像验证 Docker 引擎安装是否正确。hello-world
$ sudo docker run hello-world $ sudo # docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 0e03bdcc26d7: Pull complete Digest: sha256:95ddb6c31407e84e91a986b004aee40975cb0bda14b5949f6faac5d2deadb4b9 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. #查看 $ sudo# docker images REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest bf756fb1ae65 13 months ago 13.3kB

卸载 Docker

  1. 卸载 Docker 引擎、CLI 和容器包:
    1. $ sudo yum remove docker-ce docker-ce-cli containerd.io
  1. 主机上的图像、容器、卷或自定义配置文件不会自动删除。要删除所有图像、容器和卷:
    1. $ sudo rm -rf /var/lib/docker #/var/lib/docker 默认工作路径
您必须手动删除任何编辑的配置文件。
port # 查看映射端口对应的容器内部源端口 pause # 暂停容器 ps # 猎户容器列表 pull # 从docker镜像源服务器拉取指定镜像或者库镜像 push # 推送指定镜像或者库镜像至docker源服务器 restart # 重启运行的容器 rm # 移除一个或多个容器 rmi # 移除一个或多个镜像 (无容器使用该镜像才可删除,否则需要删除相关容器才可继续或 -f 强制删除) run # 创建一个新的容器并运行一个命令 save # 保存一个镜像为一个 tar 包【对应 load】 search # 在 docker hub 中搜索镜像 start # 启动容器 stop # 停止容器 tag # 给源中镜像打标签 top # 查看容器中运行的进程信息 unpause # 取消暂停容器 version # 查看 docker版本号 wait # 截取容器停止时的退出状态值

好处
redis,mysql :不同的集群使用不同的网络,保证集群的安全和健康

网络连通

docker中的网络模式有哪些?就是DRIVER展示的那一列
  1. bridge 桥接模式,使用宿主机进行桥接
  1. null 就是不配置网络
  1. host 就是和宿主机共享网络
  1. container 就是容器网络链接(用的很少!局限很大)
一般都会使用桥接模式。
[root@izm5e2qhnn7p36yrpjgvrez ~]# docker network --help Usage: docker network COMMAND Manage networks Commands: connect     Connect a container to a network create     Create a network disconnect Disconnect a container from a network inspect     Display detailed information on one or more networks  ls         List networks prune       Remove all unused networks  rm         Remove one or more networks [root@izm5e2qhnn7p36yrpjgvrez ~]# docker network connect --help Usage: docker network connect [OPTIONS] NETWORK CONTAINER Connect a container to a network Options:      --alias strings           Add network-scoped alias for the container      --driver-opt strings     driver options for the network      --ip string               IPv4 address (e.g., 172.30.100.104)      --ip6 string             IPv6 address (e.g., 2001:db8::33)      --link list               Add link to another container      --link-local-ip strings   Add a link-local address for the container
测试打通tomcat01 -mynet
直接加入到那个网络加入进来
一个容器两个IP地址

部署Redis集群

notion image

搭建步骤

  • 1、下载redis镜像
docker pull redis
查看本地镜像,可以使用命令docker images
  • 2、创建虚拟网卡
创建虚拟网卡,主要是用于redis-cluster能于外界进行网络通信,一般常用桥接模式。
[root@iZm5e2qhnn7p36yrpjgvreZ /]# docker network create redis-net 603b5f8697d234f46303054d6fceb3df9ce73e74542bd95482fa629094e670a1
查看docker的网卡信息,可使用命令docker network ls
[root@iZm5e2qhnn7p36yrpjgvreZ /]# docker network ls NETWORK ID     NAME       DRIVER   SCOPE 6b9e901fe192   bridge     bridge   local 66fbb2ea3040   host       host     local 6d7a3d6948b0   none       null     local 603b5f8697d2   redis-net   bridge   local
查看dockerr网络详细信息,可使用命令docker network inspect redis-net
[root@iZm5e2qhnn7p36yrpjgvreZ /]# docker network inspect redis-net [   {        "Name": "redis-net",        "Id": "603b5f8697d234f46303054d6fceb3df9ce73e74542bd95482fa629094e670a1",        "Created": "2021-02-25T15:52:55.203842464+08:00",        "Scope": "local",        "Driver": "bridge",        "EnableIPv6": false,        "IPAM": {            "Driver": "default",            "Options": {},            "Config": [               {                    "Subnet": "172.20.0.0/16", 地址                    "Gateway": "172.20.0.1"   分配的地址               }           ]       },        "Internal": false,        "Attachable": false,        "Ingress": false,        "ConfigFrom": {            "Network": ""       },        "ConfigOnly": false,        "Containers": {},        "Options": {},        "Labels": {}   } ]
  • 3、创建redis配置文件模板
mkdir -p /home/redis-cluster cd /home/redis-cluster vim redis-cluster.tmpl
在redis-cluster.tmpl中输入以下内容
port ${PORT} protected-mode no cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 115.28.136.212 cluster-announce-port ${PORT} cluster-announce-bus-port 1${PORT} appendonly yes
各节点解释如下所示:
  • port:节点端口,即对外提供通信的端口
  • cluster-enabled:是否启用集群
  • cluster-config-file:集群配置文件
  • cluster-node-timeout:连接超时时间
  • cluster-announce-ip:集群各节点IP地址
  • cluster-announce-port:集群节点映射端口
  • cluster-announce-bus-port:集群总线端口
  • appendonly:持久化模式
cluster-announce-ip:这个IP需要特别注意一下,如果要对外提供访问功能,需要填写宿主机的IP,如果填写docker分配的IP(172.x.x.x),可能会导致部分集群节点在跳转时失败。
  • 4、创建节点配置文件
在redis-cluser中执行以下命令
for port in $(seq 6111 6116); \ do \ mkdir -p ./${port}/conf \ && PORT=${port} envsubst < ./redis-cluster.tmpl > ./${port}/conf/redis.conf \ && mkdir -p ./${port}/data; \ done
验证上述命令执行的结果是否正确
[root@iZm5e2qhnn7p36yrpjgvreZ redis-cluster]# tree /home/redis-cluster /home/redis-cluster ├── 6111 │   ├── conf │   │   └── redis.conf │   └── data ├── 6112 │   ├── conf │   │   └── redis.conf │   └── data ├── 6113 │   ├── conf │   │   └── redis.conf │   └── data ├── 6114 │   ├── conf │   │   └── redis.conf │   └── data ├── 6115 │   ├── conf │   │   └── redis.conf │   └── data ├── 6116 │   ├── conf │   │   └── redis.conf │   └── data └── redis-cluster.tmpl [root@iZm5e2qhnn7p36yrpjgvreZ redis-cluster]# cat /home/redis-cluster/611{1..6}/conf/redis.conf port 6111 protected-mode no cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 115.28.136.212 cluster-announce-port 6111 cluster-announce-bus-port 16111 appendonly yes port 6112 protected-mode no cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 115.28.136.212 cluster-announce-port 6112 cluster-announce-bus-port 16112 appendonly yes port 6113 protected-mode no cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 115.28.136.212 cluster-announce-port 6113 cluster-announce-bus-port 16113 appendonly yes port 6114 protected-mode no cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 115.28.136.212 cluster-announce-port 6114 cluster-announce-bus-port 16114 appendonly yes port 6115 protected-mode no cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 115.28.136.212 cluster-announce-port 6115 cluster-announce-bus-port 16115 appendonly yes port 6116 protected-mode no cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 115.28.136.212 cluster-announce-port 6116 cluster-announce-bus-port 16116 appendonly yes
  • 5、创建redis节点容器
执行以下命令即可
for port in $(seq 6111 6116); \ do \ docker run -it -d -p ${port}:${port} -p 1${port}:1${port} \ --privileged=true -v /home/redis-cluster/${port}/conf/redis.conf:/usr/local/etc/redis/redis.conf \ --privileged=true -v /home/redis-cluster/${port}/data:/data \ --restart always --name redis-${port} --net redis-net \ --sysctl net.core.somaxconn=1024 redis redis-server /usr/local/etc/redis/redis.conf; \ done
验证容器是否创建成功

  • 6、创建redis-cluster集群
进入一个容器节点
docker exec -it redis-6111 bash

安装tomcat

拉去镜像
docker pull tomcat
启动tomcat
docker run -d --name clover-tomcat \ -p 8080:8080 \ --restart=always --network common-network \ -v /home/tomcat/webapps:/usr/local/tomcat/webapps \ tomcat:latest #在network中的地址           "Name": "clover-tomcat",                "EndpointID": "48d13338d453d8929632bcfe023cb624a5ad2b0f0234c391a29cbd4ddc5347d8",                "MacAddress": "02:42:ac:15:00:04",                "IPv4Address": "172.21.0.4/16",                "IPv6Address": ""           },
注意还需要在webapps下创建ROOT文件夹然后把需要的资源放入

安装nginx同时配置https

拉去镜像
docker pull nginx
拷贝nginx镜像中的文件到宿主机
docker run --name tmp-nginx -d nginx:latest mkdir -p /home/nginx docker cp tmp-nginx:/etc/nginx/conf.d /home/nginx/ docker cp tmp-nginx:/usr/share/nginx/html /home/nginx/ docker stop tmp-nginx docker rm tmp-nginx
启动nginx服务
docker run --name clover-nginx -d \ -p 80:80 -p 443:443 \ --restart=always --network common-network \ -v /home/nginx/conf.d:/etc/nginx/conf.d:ro \ -v /home/nginx/ssl:/etc/nginx/ssl:ro \ -v /home/nginx/html:/usr/share/nginx/html:ro \ nginx:latest
以上命令:
  • 命名容器为vk-nginx,后台运行
  • 映射宿主机80、443端口到容器的80、443端口
  • 挂载宿主机目录/home/nginx/conf.d到容器目录/etc/nginx/conf.d
  • 挂载宿主机目录/home/nginx/ssl到容器目录/etc/nginx/ssl
  • 挂载宿主机目录/home/nginx/html到容器目录/usr/share/nginx/html
配置https
server { listen 80; server_name www.clover-blog.xyz; return 301 https://$server_name$request_uri; } server { # SSL configuration listen 443 ssl; listen [::]:443 ssl; server_name www.clover-blog.xyz; ssl_certificate /etc/nginx/ssl/5397881_clover-blog.xyz.pem; ssl_certificate_key /etc/nginx/ssl/5397881_clover-blog.xyz.key; ssl_session_timeout 5m; ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers HIGH:!ADH:!EXPORT56:RC4+RSA:+MEDIUM; ssl_prefer_server_ciphers on; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; root /usr/share/nginx/html/voidking/; index index.html; } }
重启nginx
docker restart clover-nginx
查看是否启动成功
docker ps docker logs clover-nginx
