Project: docker deployment zabbix

Environmental deployment

2 physical machine: zabbix-server 192.168.233.96 zabbix-agent 192.168.233.95

docker version: (docker --virsion or docker info can see) Server Version: 19.03.1

zabbix version: (/ usr / local / zabbix / sbin / zabbix_server --V can see) zabbix 4.0

docker mirror source :( downloaded to /etc/yum.repo.d/ directory) wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

 

Installation docker

yum install docker-ce -y (Free Edition is -ce business community paid version is -ee)

Time to resolve dependencies may report the following error

Error: Package: containerd.io-1.2.6-3.3.el7.x86_64 (docker-ce-stable)
           Requires: container-selinux >= 2:2.74

Error reason: low container-selinux package required version requires version 2.74

Solution: The official website mirror.centos.org to find the required version of the package, download and install

 

yum -y install http://mirror.centos.org/centos-7/7/extras/x86_64/Packages/container-selinux-2.74-1.el7.noarch.rpm

Log Ali cloud -> Go to Control Panel -> Services -> Container Services Mirror -> Mirror accelerator

Write a script and execute (implement mirroring acceleration)

When deployed with mariadb10.2 zabbix the best versions of the following, including 10.2 as 10.3.17 version has some restrictions on the length of the field, this will lead to error down data when it directly with 10.2, 10.2 is mariadb a stable version given in the official website, or a good use

 

After use interface are zabbix

 

 

The process of creating containers docker-compose

# Start container docker-compose.yaml defined in the document, and is running in the background 
[root @ master ~] # docker -compose up -d

Usage docker-compose command

Commands:
  build              Build or rebuild services　　　　　　　　　　　　　　　　　　　　　　　
  bundle             Generate a Docker bundle from the Compose file
  config             Validate and view the Compose file
  create             Create services
  down               Stop and remove containers, networks, images, and volumes
  events             Receive real time events from containers
  exec               Execute a command in a running container
  help               Get help on a command
  images             List images
  kill               Kill containers
  logs               View output from containers
  pause              Pause services
  port               Print the public port for a port binding
  ps                 List containers
  pull               Pull service images
  push               Push service images
  restart            Restart services
  rm                 Remove stopped containers
  run                Run a one-off command
  scale              Set number of containers for a service
  start              Start services
  stop               Stop services
  top                Display the running processes
  unpause            Unpause services
  up                 Create and start containers
  version            Show the Docker-Compose version information

build or re-build services 
help command help 
pause to pause the service 
exec into a docker container interface 
kill kill container 
logs show docker-compose.yaml file output the contents of the container 
ps shows the active container 
pull the pull service mirroring 
restart to restart the service 
rm delete stop container 
run run container 
number of containers scale settings of the service 
start to open service 
stop stop the service 
up to create and launch container 
config test docker-comose.yaml file syntax is ok

Syntax Parameters docker-compose.yaml instructions in the file

A docker-compose.yaml file broadly divided into: version, services, network

version

version can be 1,2,3 This is a great version, there is a small version, such as 1.0,2.2,3.3, etc., must be developed version version when defining yaml files, each version of the syntax may not be the same, can refer to the article below to the official documentation for details

service

1.service defined service name, service under a defined service name

Version: '3.3' 
Services: 
  Service Name:

 

2. Under the name of a service tag has container_name, image, restart, privileged, environment, volumes, ports, links, etc.

container_name: Name vessel defined 
image: Mirror Name 
restart 
    restart: "NO" # do not restart 
    restart: always # always restart 
    restart: on-failure when the failure to restart # 
    restart: unless-stopped # unless stopped 
privileged: get the highest authority 
environment: set system environment variables 
    KEY1: VALUE1 
    the KEY2: VALUE2 
volumes mapping container volume 
    - host_path: CONTAINER_PATH 
    - host_path: CONTAINER_PATH 
the ports: port mapping container 
    - host_port: CONTAINER_PORT 
links: connecting the container 
    - SERVICE_NAME 
depends_on: definition of container in the order 
    - ZABBIX-Server 
    - ZABBIX -web 
    - MySQL-Server
