Docker application deployment example

Docker application deployment

1. Deploy MySQL

1. Search mysql mirror

docker search mysql

2. Pull mysql image

docker pull mysql:5.6

3. Create a container, set port mapping, directory mapping

# 在/root目录下创建mysql目录用于存储mysql数据信息
mkdir ~/mysql
cd ~/mysql

docker run -id \
-p 3307:3306 \
--name=c_mysql \
-v $PWD/conf:/etc/mysql/conf.d \
-v $PWD/logs:/logs \
-v $PWD/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 \
mysql:5.6

• Parameter Description:
  • -p 3307:3306 : Map port 3306 of the container to port 3307 of the host.
  • -v $PWD/conf:/etc/mysql/conf.d : Mount conf/my.cnf in the host's current directory to /etc/mysql/my.cnf in the container. configuration directory
  • -v $PWD/logs:/logs : Mount the logs directory under the current directory of the host to /logs of the container. log directory
  • -v $PWD/data:/var/lib/mysql : Mount the data directory under the current directory of the host to /var/lib/mysql of the container. data directory
  • **-e MYSQL_ROOT_PASSWORD=123456: **Initialize the root user's password.

4. Enter the container and operate mysql

docker exec –it c_mysql /bin/bash

5. Use an external machine to connect to mysql in the container
   

2. Deploy Tomcat

1. Search tomcat mirror

docker search tomcat

2. Pull the tomcat image

docker pull tomcat

3. Create a container, set port mapping, directory mapping

# 在/root目录下创建tomcat目录用于存储tomcat数据信息
mkdir ~/tomcat
cd ~/tomcat

docker run -id --name=c_tomcat \
-p 8080:8080 \
-v $PWD:/usr/local/tomcat/webapps \
tomcat 

• Parameter Description:

  • **-p 8080:8080: **Map port 8080 of the container to port 8080 of the host

    **-v $PWD:/usr/local/tomcat/webapps: **Mount the current directory in the host to the webapps of the container

4. Use an external machine to access tomcat

3. Deploy Nginx

1. Search nginx mirror

docker search nginx

2. Pull the nginx mirror

docker pull nginx

3. Create a container, set port mapping, directory mapping

# 在/root目录下创建nginx目录用于存储nginx数据信息
mkdir ~/nginx
cd ~/nginx
mkdir conf
cd conf
# 在~/nginx/conf/下创建nginx.conf文件,粘贴下面内容
vim nginx.conf

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    
    
    worker_connections  1024;
}


http {
    
    
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

docker run -id --name=c_nginx \
-p 80:80 \
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \
-v $PWD/logs:/var/log/nginx \
-v $PWD/html:/usr/share/nginx/html \
nginx

• Parameter Description:
  • -p 80:80 : Map port 80 of the container to port 80 of the host.
  • -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf : Mount /conf/nginx.conf in the current directory of the host to: /etc/nginx/nginx.conf in the container. configuration directory
  • -v $PWD/logs:/var/log/nginx : Mount the logs directory under the current directory of the host to /var/log/nginx of the container. log directory

4. Access nginx from an external machine
   

4. Deploy Redis

1. Search redis mirror

docker search redis

2. Pull the redis image

docker pull redis:5.0

3. Create a container and set up port mapping

docker run -id --name=c_redis -p 6379:6379 redis:5.0

4. Connect to redis using an external machine

./redis-cli.exe -h 192.168.149.135 -p 6379

redis

2. 拉取redis镜像

```shell
docker pull redis:5.0

3. Create a container and set up port mapping

docker run -id --name=c_redis -p 6379:6379 redis:5.0

4. Connect to redis using an external machine

./redis-cli.exe -h 192.168.149.135 -p 6379
