docker总结

一. Docker的安装

准备
确保内核版本大于3.1 并更新yum
```
uname -r
yum update
```

添加仓库安装

  yum install -y yum-utils device-mapper-persistent-data lvm2    # 安装yum的辅助包


  yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo  # 设置阿里的镜像

  yum install docker-ce       # 安装

启动并加入开机启动

    
    systemctl start docker
    systemctl enable docker
    docker version

配置远程访问

   vim /usr/lib/systemd/system/docker.service

把 ExecStart=/usr/bin/dockerd 这一行改为

 ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375

重启docker服务

  systemctl daemon-reload #通知systemd重载配置文件
  systemctl restart docker

此时访问 http://IP:2375/version 可以看到版本为17.05.0-ce

设置国内镜像源
新增/修改 /etc/docker/daemon.json

    {
              "registry-mirrors": ["https://registry.docker-cn.com"]
    }

安装 docker-compose
参见GitHub上的shell

 docker-compose --version # 测试安装成功了吗

TLS
在/etc/docker目录下新建shell

# 客户端远程连接
# docker -H 192.168.1.130:2376 --tlsverify --tlscacert ~/.docker/ca.pem --tlscert ~/.docker/cert.pem --tlskey ~/.docker/key.pem ps -a

echo -e "\e[1;32mAll be done.\e[0m"

执行脚本，设置 /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -D -H tcp://0.0.0.0:2376 --tlsverify --tlscacert=/etc/docker/certs.d/ca.pem --tlscert=/etc/docker/certs.d/server-cert.pem --tlskey=/etc/docker/certs.d/server-key.pem

重新加载配置文件重启docker。下载tls-client-certs-.tar 设置idea
URL： https://IP:2376
把下载的文件夹放上，主要去掉-

二 . rabbitmq

拉取镜像

docker pull rabbitmq:management

配置命令

#!/bin/bash
docker run -d --name rabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=redSoft123  -p 5672:5672 -p 15672:15672 rabbitmq:management

添加执行权限执行ok

常用命令
停止： docker ps
docker stop [id]
如果修改了启动shell的文件则 docker rm [id]
启动 docker start [id]
初次启动执行如上脚本

三. redis

配置命令

#!/bin/bash
docker run --name redis -p 6379:6379 -v /Users/fengfan/doc/temp/redis_temp_data:/data -d redis:latest  redis-server --appendonly yes --requirepass "123456"
