1. Zabbix server-side configuration

Configure the following on the zabbix-server server:

1.1 Mirror preparation

Download images: mysql, zabbix/zabbix-server-mysql, zabbix/zabbix-web-nginx-mysql

Docker pull mysql:5.7docker pull zabbix/zabbix-server-mysqldocker pull zabbix/zabbix-web-nginx-mysql

1.2 start mysql:5.7

Docker run-- name zabbix_mysql-- hostname zabbix_mysql-- restart=always-e MYSQL_ROOT_PASSWORD= "123456"-e MYSQL_USER= "zabbix"-e MYSQL_PASSWORD= "123456"-e MYSQL_DATABASE= "zabbix"-p 3306-v / home/docker/data/mysql:/var/lib/mysql-d mysql:5.7

1.3 start zabbix_server

Docker run-- name zabbix_server-- restart=always-- link zabbix_mysql:mysql-e DB_SERVER_HOST= "mysql"-e MYSQL_USER= "zabbix"-e MYSQL_DATABASE= "zabbix"-e MYSQL_PASSWORD= "123456"-v / etc/localtime:/etc/localtime:ro-v / home/docker/data/zabbix:/usr/lib/zabbix-p 10051-d zabbix/zabbix-server-mysql

1.4 start zabbix_nginx_web

Docker run-- name zabbix_web-- restart=always-- link zabbix_mysql:mysql-- link zabbix_server:zabbix_server-e DB_SERVER_HOST= "mysql"-e MYSQL_USER= "zabbix"-e MYSQL_PASSWORD= "123456"-e MYSQL_DATABASE= "zabbix"-e ZBX_SERVER_HOST= "zabbix_server"-e PHP_TZ= "Asia/Shanghai"-p 80:80-p 8443vis443-d zabbix/zabbix-web-nginx-mysql

At this point, the browser accesses port 80 of the host to use the zabbix-server service.

# browser opens the following address, where 192.168.1.an is the zabbix server IP

45.115.243./zabbix

Admin, password: zabbix

[root@localhost ~] # docker restart zabbix_mysqlzabbix_ MySQL [root @ localhost ~] # docker restart zabbix_serverzabbix_ server [root @ localhost ~] # docker restart zabbix_web

192.168.1.a/zabbix

2. Zabbix-agent configuration

Install agent on the machine to be monitored and configure it as follows:

2.1 Mirror preparation

Download Image: zabbix/zabbix-agent

Docker pull zabbix/zabbix-agent

2.2 start zabbix-agent

# 172.17.0.an is the native zabbix. If it is not native, change it to the IP address of zabbix-server

Docker run-- name zabbix_agent-- restart=always\-- p 10050 ZBX_HOSTNAME= 10050 zabbix_agent\-e ZBX_SERVER_HOST= "172.17.0.a"\-e ZBX_SERVER_PORT=10051\-d zabbix/zabbix-agent

# ZBX_HOSTNAME is configured as the host name of the corresponding agent added in zabbix-server

At this point, you can add the newly started agent to the zabbix-server, and then configure the zabbix, and the installation is complete.

3. Docker starts up

3.1 docker service joins boot startup

Systemctl enable docker

# if you successfully join the boot boot, you will be prompted as follows:

Created symlink from / etc/systemd/system/multi-user.target.wants/docker.service to / usr/lib/systemd/system/docker.service.

3.2Boot of docker container

The-- restart=always parameter is added to the docker run startup parameters. When the container exits, such as a restart, it will restart automatically. There is no need to set the container startup script separately.

4. Export and import of images

For machines that cannot be connected to the Internet, you cannot use docker pull to pull images directly from the Internet, so you need to use the export and import functions of the container.

4.1 Export of images

View currently available images

Docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

Docker.io/zabbix/zabbix-agent latest 19e75a9513da 23 hours ago 56.67 MB

Docker.io/zabbix/zabbix-server-mysql latest 3abad97a6d75 24 hours ago 107.3 MB

Docker.io/zabbix/zabbix-web-nginx-mysql latest 039292d2eae1 26 hours ago 176.8 MB

Docker.io/mysql 5.7 d9ad3d6d1a44 5 months ago 298.3 MB

Export Mirror

Docker save-o / opt/zabbixagent.tar zabbix/zabbix-agent:latest

# / opt/zabbix_agent.tar the location and name of the export image

# zabbix/zabbix-agent:latest exports REPOSITORY and TAG of an image

Docker save-o / opt/zabbix_server.tar zabbix/zabbix-server-mysql:latestdocker save-o / opt/zabbix_nginx.tar zabbix/zabbix-web-nginx-mysql:latestdocker save-o / opt/zabbix_mysql.tar mysql:5.7

When we look at the list of files under / opt, we can see that the export is successful.

Ll / opt-rw- 1 root root 61114368 Dec 16 14:54 zabbix_agent.tar-rw- 1 root root 305571840 Dec 16 15:02 zabbix_mysql.tar-rw- 1 root root 182195200 Dec 16 15:01 zabbix_nginx.tar-rw- 1 root root 112269824 Dec 16 15:00 zabbix_server.tar

4.2 Import of images

Execute on a machine that has docker installed but does not have the relevant configuration:

# add boot boot

Systemctl enable docker

# start the docker process

Systemctl start docker

View currently available images

Docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

You can see that the image is empty. Import the image:

Docker load-I / opt/zabbix_agent.tar

# / opt/zabbix_agent.tar is the image just exported

Docker load-I / opt/zabbix_server.tardocker load-I / opt/zabbix_nginx.tardocker load-I / opt/zabbix_mysql.tar

Using docker images again, you can see that the image has been successfully imported and can be used on the currently unconnected machine.

5. Zabbix related logs

There is no special log file in the container, so there is no log file storage mapping. We can view the running log of zabbix by using the following command:

Docker logs zabbix_serverdocker logs zabbix_agentdocker logs zabbix_webdocker logs zabbix_mysql

6. Zabbix redeployment and migration

For zabbix that uses docker, because we have mapped the storage, the configuration of the database and zabbix can be migrated to other machines, copy the following directory on the host machine, and then redeploy the zabbix container.

/ home/docker/data/zabbix

/ home/docker/data/mysql

Because the mapping is stored on the host, cloud backup can be used to prevent data loss.
