Docker install Nginx

# 1. Search image search. It is recommended that everyone go to docker to search, and you can see the help documentation information.

# 2. Download image pull

# 3. Run the test

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and

Working. Further configuration is required.

For online documentation and support please refer to

Nginx.org.

Commercial support is available at

Nginx.com.

Thank you for using nginx.

# enter the container

[root@dockertest home] # docker exec-it nginx01 / bin/bash

Question to consider: every time we change the nginx configuration file, we need to go inside the container. It's very troublesome. If you want to provide a mapping path outside the container, you can modify the file outside the container and automatically inside the container. -v data volume! Can be realized.

Assignment: docker to install a tomcat

# official use

Docker run-it-- rm tomcat:9.0

# all our previous launches are in the background. After stopping the container, the container can still find docker run-it-- rm, which is usually used for testing, indicating deletion after use.

# download and then start

Docker pull tomcat

# start and run

Docker run-d-p 3355 8080-- name tomcat01 tomcat

# there is no problem with test access (404 returned)

# enter the container

[root@dockertest home] # docker exec-it tomcat01 / bin/bash

# found problems: 1. Fewer linux commands. 2. No webapps. Reason: Aliyun image is the smallest image by default, and all unnecessary images are removed.

# ensure a minimum runnable environment!

Question to consider: we have to deploy the project in the future. Is it very troublesome to enter the container every time? If only I could provide a mapping path outside the container, webapps, we would automatically synchronize to the inside if we put the project on the outside!

Job: deploy es + kibana

# es exposes a lot of ports!

# es consumes very much memory

# es data generally needs to be placed in a secure directory! Mounting

#-net somenetwork? Network configuration

# start

Docker run-d-- name elasticsearch-p 9200 discovery.type=single-node 9200-p 9300 discovery.type=single-node 9300

# after startup, linux jammed docker stats to check the status of cpu

# es consumes a lot of memory and takes up 1. 1? G.

# View docker stats

# Test whether es is successful or not

# close and increase the memory limit

# close, increase the memory limit, modify the configuration file-e environment configuration modification (- Xms64-Xmx512 represents a minimum memory of 64m, a maximum memory of 512m)
