docker安装

方法一:一键安装

代码语言:javascript
复制
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

方法二:常规安装

1.安装yum-utilsyum-utils提供了yum-config-manager管理工具

代码语言:javascript
复制
yum install -y yum-utils

2.配置国内镜像源

3.安装Docker Engine-Community 和 containerd :

代码语言:javascript
复制
yum install docker-ce docker-ce-cli containerd.io

方法三:本地安装

1.查看操作系统内核,从官网下载对应版本

代码语言:javascript
复制
uname -r

官网下载地址:https://download.docker.com/linux/static/stable/

下载好的文件解压并放置到/usr/bin目录中

代码语言:javascript
复制
# 解压
tar -zxvf docker-20.10.x.tgz
# 移动解压出来的二进制文件到 /usr/bin 目录中
mv docker/* /usr/bin/

2.配置添加systemd,编辑docker的系统服务文件vim /usr/lib/systemd/system/docker.service

代码语言:javascript
复制
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target

3.重新加载系统服务和重启docker

代码语言:javascript
复制
systemctl daemon-reload
systemctl restart docker

基础命令

启动docker服务和开机自启:

代码语言:javascript
复制
systemctl start docker
systemctl enable docker
代码语言:javascript
复制
# 查看镜像
docker images
# 删除镜像
docker rmi <image_id>
# 查看容器
docker container ls
# 启动/重启容器
docker start/restart <container_id>
# 删除容器
docker rm <container_id>
# 查看挂载目录
docker inspect <container_id> | grep "Mounts" -A 20

运行容器

如需指定端口映射使用-p,如需暴露容器所有端口(和宿主机共享网络),使用--net=host

Tomcat8

app根目录上传至服务器,然后将根目录映射至容器/usr/local/tomcat/webapps/目录下:

代码语言:javascript
复制
docker run --name={app_name} \
	--net=host \
	-v /root/tomcat/webapps/{app_name}:/usr/local/tomcat/webapps/{app_name} \
	-d tomcat:8.5.38-jre8

Mysql

代码语言:javascript
复制
docker run --name=mysql \
	-p 3306:3306 \
	-v /root/mysql/conf:/etc/mysql/conf.d \
	-v /root/mysql/logs:/logs \
	-v /root/mysql/data:/var/lib/mysql \
	-e MYSQL_ROOT_PASSWORD='password' \
	-d mysql:5.7 mysqld \
	--innodb-buffer-pool-size=80M \
	--character-set-server=utf8mb4 \
	--collation-server=utf8mb4_unicode_ci \
	--default-time-zone=+8:00 \
	--lower-case-table-names=1

Redis

代码语言:javascript
复制
docker run --name=redis \
	--net=host \
	-d redis:latest redis-server \
	--requirepass "password"

ActiveMQ

代码语言:javascript
复制
docker run --name=activemq \
	-p 8161:8161  	\ # web页面管理端口
	-p 61616:61616  \ # 业务端口
	-v /root/activemq/data:/data/activemq \
	-v /root/activemq/log:/var/log/activemq \
	-e ACTIVEMQ_ADMIN_LOGIN=admin \
	-e ACTIVEMQ_ADMIN_PASSWORD={passowrd} \
	-d webcenter/activemq:latest

MongoDB

代码语言:javascript
复制
docker run --name=mongodb \
	-p 27017:27017 \
	-v /root/mongodb/data:/data/db \
	-d mongo:4.0.6 \
	--auth

进入容器设置超管账号密码:

代码语言:javascript
复制
docker exec -it mongodb mongo admin
db.createUser({ user: 'admin', pwd: 'password', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });

为其他库设置访问权限:

代码语言:javascript
复制
db.auth("admin","password");   #验证超管身份
use yourdatabase;
db.createUser({user:'user',pwd:'password',roles:[{role:'dbOwner',db:'yourdatabase'}]});

ElasticSearch

代码语言:javascript
复制
docker run --name=es \
	--net=host \
	-v /root/es/data:/usr/share/elasticsearch/data \
	-v /root/es/logs:/usr/share/elasticsearch/logs \
	-e "discovery.type=single-node" \
	-d elasticsearch:7.3.2

设置访问密码

进入容器:

代码语言:javascript
复制
docker exec -it es /bin/bash

编辑配置文件elasticsearch.yml,添加如下内容:

代码语言:javascript
复制
xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true

重启容器,之后执行如下命令开始设置密码:

代码语言:javascript
复制
bin/elasticsearch-setup-passwords interactive

安装分词插件ik

进入容器执行如下命令,然后重启容器,注意选择和es版本匹配的分词插件:

代码语言:javascript
复制
bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.3.2/elasticsearch-analysis-ik-7.3.2.zip

Kibana

注意镜像使用和es使用一样的版本号:

代码语言:javascript
复制
docker pull kibana:7.3.2   

宿主机创建配置文件/root/elk/kibana.yml

代码语言:javascript
复制
server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://172.17.0.1:9200" ]   # 注意是容器内访问
elasticsearch.username: "kibana"         #ES中配置的kibana账号和密码
elasticsearch.password: "password"
xpack.monitoring.ui.container.elasticsearch.enabled: true

运行:

代码语言:javascript
复制
docker run --name=kibana \
	--net=host \
	-v /root/elk/kibana.yml:/usr/share/kibana/config/kibana.yml \
	-d kibana:7.3.2 \
	--log-driver json-file \
	--log-opt max-size=100m \
	--log-opt max-file=2 \
	--restart=always 

Nacos

事先准备好配置文件/root/nacos/conf/application.properties

代码语言:javascript
复制
docker run --name=nacos \
	-p 8848:8848 \
	-p 9848:9848 \
	-p 9849:9849 \
	-v /root/nacos/logs/:/home/nacos/logs \
	-v /root/nacos/data/:/home/nacos/data \
	-v /root/nacos/conf/application.properties:/home/nacos/conf/application.properties \
	-e MODE=standalone \
	-e JVM_XMS=512m \
	-e JVM_XMX=512m \
	-e JVM_XMN=256m \
	-d nacos/nacos-server

Nginx

代码语言:javascript
复制
docker run --name=nginx \
	--net=host \
	-v /root/nginx/html:/usr/share/nginx/html \
	-v /root/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
	-v /root/nginx/logs:/var/log/nginx \
	-v /root/nginx/conf.d:/etc/nginx/conf.d \
	-d nginx

注意:如果指定了-v,则宿主机目录会覆盖容器目录(-v的参数只能是目录)。如果需要使用自定义配置,则应在nginx.confconf.d存入配置文件再启动,否则应取消这2个-v,以使用默认配置。

Gitlab

拉取Gitlab镜像

代码语言:javascript
复制
docker pull gitlab/gitlab-ce:latest

运行容器

代码语言:javascript
复制
docker run --name=gitlab \
    -p 9980:80 \
    -p 9922:22 \
    -v /opt/docker/gitlab/config:/etc/gitlab \
    -v /opt/docker/gitlab/logs:/var/log/gitlab \
    -v /opt/docker/gitlab/data:/var/opt/gitlab \
    -d gitlab/gitlab-ce

注意:因为容器里会使用到22端口,所以这里不要使用--net=host,以免和宿主机的22端口发生冲突。

修改配置

进入容器内部

代码语言:javascript
复制
docker exec -it gitlab /bin/bash

修改gitlab.rb,填写gitlab访问地址,这里应当填写宿主机的ip地址

代码语言:javascript
复制
vi /etc/gitlab/gitlab.rb
 
#加入如下内容:
#gitlab访问地址,可以写域名。如果端口不写的话默认为80端口
external_url 'http://192.168.124.194'
#ssh主机ip
gitlab_rails['gitlab_ssh_host'] = '192.168.124.194'
#ssh连接端口
gitlab_rails['gitlab_shell_ssh_port'] = 9922
 
# 退出vi,让配置生效
gitlab-ctl reconfigure

修改访问端口号:

代码语言:javascript
复制
vi /opt/gitlab/embedded/service/gitlab-rails/config/gitlab.yml

找到以下内容,修改默认的80端口为自定义

代码语言:javascript
复制
...
  gitlab:
    host: 192.168.124.194
    port: 80 # 这里改为9980
    https: false
...

重启gitlab后退出容器

代码语言:javascript
复制
gitlab-ctl restart
exit

访问地址为:http://192.168.124.194:9980/

首次进入需要使用root账号,可以使用如下命令查看root账号密码

代码语言:javascript
复制
docker exec -it gitlab cat /etc/gitlab/initial_root_password

重置密码

可通过gitlab控制台直接设置用户密码

代码语言:javascript
复制
# 进入容器内部
docker exec -it gitlab /bin/bash
 
# 进入控制台
gitlab-rails console -e production
 
# 查询id为1的用户,id为1的用户是超级管理员
user = User.where(id:1).first
# 修改密码为abc123456
user.password='abc123456'
# 保存
user.save!
# 退出
exit

其他

修改容器时区为中国时区

代码语言:javascript
复制
docker cp /usr/share/zoneinfo/Asia/Shanghai {container_id}:/etc/localtime

FAQ

Centos安装docker报错

如果安装docker时出现了container-selinux >= 2.9错误,类似如下:

代码语言:javascript
复制
Error: Package: containerd.io-1.2.13-3.2.el7.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2:2.74
Error: Package: 3:docker-ce-19.03.12-3.el7.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2:2.74
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

这个报错是container-selinux版本低或者是没安装的原因,yum 安装container-selinux一般的yum源又找不到这个包,需要安装epel源才能yum安装container-selinux,然后再安装docker-ce就可以了。
