追加更新内容

项目中如果遇到会不时的更新.请大家及时关注哦!!!

zookeeper

kafka

es

使用场景

本地、测试、生产环境使用一致的环境,不会导致本地与线上环境的差异.轻量级的docker可以满足.

前置条件

在安装应用之前需要安装docker.笔者是在vmware中安装的docker,因为迁移会比较方便

vmware(非必要)

docker

docker-compose

使用docker-compose编排安装应用

前置条件已经安装了docker docker-compose.如何安装自行百度.

安装常用应用

mysql

tomcat

docker-ui

nginx

redis

jenkins

kafka

zookeeper

es

在安装es之前需要设置虚拟内存不然会报错

设置虚拟内存虚拟内存

sudo sysctl -w vm.max_map_count=262144

新建docker-compose.yml

volumes为挂载的目录,目的是为了让你修改的文件保存在你的本地目录中.这样容器删了就不会丢失数据.这个例子中我挂在的目录为./volumes/....这个目录可以自行修改

测试应用是否都安装成功

因为我的docker是安装在本地虚拟机的linux系统上,首先查看虚拟机的ip地址172.16.217.128

虚拟机ubuntu ip地址.png

docker_ui

端口9000

访问http://172.16.217.128:9000.查看是否安装完成

image.png

页面能够正常访问,测试通过

jenkins

端口12002

访问http://172.16.217.128:12002.查看是否安装完成

mysql

ip: 172.16.217.128

端口: 3306

账号: root

密码: zxcv1234

---

ps: 账号密码是在上文中的docker-compose.yml中设置的

使用数据库连接工具navicat(可以选择自己的连接工具,我这里使用这个)

zookeeper

kafka依赖于zookeeper,所以我们只要测试kafka就行了
