This article introduces how to use Docker to deploy middleware services commonly used in enterprise work.
Nginx
shell docker run -d \ -p 80:80 --name nginx-server-conf \ -v /opt/nginx-server-conf:/usr/share/nginx/html:ro \ -v /opt/nginxcon/nginx.conf:/etc/nginx/nginx.conf:ro \ nginx
Set the mapping between the host port 80 and the container's port 80, as well as the mapping between the data volume directory mounting and the directory where the container's configuration file is located. One is the Nginx homepage and the other is the server configuration file.
Tomato
shell docker run -d -p 8080:8080 \ -v /opt/tomcat-server:/usr/local/tomcat/webapps/ROOT \ tomcat:9.0
Set the host port 8080 port and container port 8080 mapping, access the host IP address plus port 8080 to view the Tomcat home page.
-vThe parameter setting is the directory mapping relationship between the webapps of the Tomcat container and the host. Add the war package in the host directory to access the web app you developed normally.
MySQL
Stand-alone deployment
MySQL long-term support versions include 5.7 and 8.0, and the one demonstrated here is 5.7.
shell docker run -d -p 3306:3306 \ --name mysql \ -v /opt/mysql/log:/var/log/mysql \ -v /opt/mysql/data:/var/lib/mysql \ -v /opt/mysql/conf:/etc/mysql \ -e MYSQL_ROOT_PASSWORD=root \ mysql:5.7
To use MySQL's built-in client access, enter the following command:
```shell docker exec -it mysql mysql -uroot -proot mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 4 Server version: 5.7.37 MySQL Community Server (GPL)

还可以通过在 docker host 上访问：
```shell
yum -y install mariadb
mysql -h 192.168.255.157 -uroot -proot -P 3306

```shell
vim /opt/mysql-master/conf/my.cnf
cat /opt/mysql-master/conf/my.cnf

重启容器，使用配置生效
docker restart mysql-master
查看状态

Oracle
```shell
oracle数据库连接信息
port:49161
sid:xe
username:system
password:oracle
49160 为ssh端口
49161 为sqlplus端口
49162 为oem端口
docker run -h oracle --name oracle -d -p 49160:22 \ -p 49161:1521 \ -p 49162:8080 \ oracleinanutshell/oracle-xe-11g ```
PostgreSQL
shell docker run -d \ --name postgres \ -e POSTGRES_PASSWORD=mysecretpassword \ -e PGDATA=/var/lib/postgresql/data/pgdata \ -v /custom/mount:/var/lib/postgresql/data \ postgres:11.20-bullseye
ElasticSearch
单个部署
部署 ElasticSearch
```shell docker pull elasticsearch:7.17.0
创建数据卷挂载目录
mkdir -p /opt/es/config mkdir -p /opt/es/data
编写配置文件，使得可以远程访问
echo "http.host: 0.0.0.0" >> /opt/es/config/elasticsearch.yml
docker run -d --name elasticsearch \ -p 9200:9200 \ -p 9300:9300 \ -e "discovery.type=single-node" \ -e ESJAVAOPTS="-Xms64m -Xmx512m" \ -v /opt/es/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \ -v /opt/es/data:/usr/share/elasticsearch/data \ -v /opt/es/plugins:/usr/share/elasticsearch/plugins \ elasticsearch:7.17.0 ```
部署 Kibana
shell docker run -d --name kibana \ -e ELASTICSEARCH_HOSTS=http://192.168.255.157:9200 \ -p 5601:5601 \ kibana:7.17.0
使用docker-compose部署
```yml version: '3' services: elasticsearch: image: docker.elastic.co/elasticsearch/elasticsearch:7.17.0 containername: elasticsearch environment: - discovery.type=single-node ports: - "9200:9200" - "9300:9300" networks: - elknetwork kibana: image: docker.elastic.co/kibana/kibana:7.17.0 containername: kibana environment: ELASTICSEARCHHOSTS: "http://elasticsearch:9200" ports: - "5601:5601" networks: - elk_network
networks: elk_network: ```
```shell
启动容器
docker-compose up -d ```
Redis
单机部署
```shell
创建挂载的目录
mkdir -p /opt/redis/conf
创建配置文件
touch /opt/redis/conf/redis.conf
docker run -d -p 6379:6379 --name redis -v /opt/redis/data:/data -v /opt/redis/conf:/etc/redis redis redis-server /etc/redis/redis.conf shell
使用redis-cli连接redis服务
some-redis指的是容器名称
docker run -it --network some-network --rm redis redis-cli -h some-redis ```
集群部署
安装 redis-cluster：3 主 3 从方式，从为了同步备份，主进行 slot 数据分片。
redis-cluster.sh：
```shell
编辑运行多个redis容器脚本文件
vim redis-cluster.sh
cat redis-cluster.sh
for port in $(seq 8001 8006); do mkdir -p /mydata/redis/node-${port}/conf touch /mydata/redis/node-${port}/conf/redis.conf cat << EOF >/mydata/redis/node-${port}/conf/redis.conf port ${port} cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 cluster-announce-ip 192.168.255.157 cluster-announce-port ${port} cluster-announce-bus-port 1${port} appendonly yes EOF
docker run -p ${port}:${port} -p 1${port}:1${port} --name redis-${port} \
-v /mydata/redis/node-${port}/data:/data \
-v /mydata/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \
-d redis:5.0.7 redis-server /etc/redis/redis.conf; \done ```
执行脚本：
shell sh redis-cluster.sh
登录 Redis 容器：
shell docker exec -it redis-8001 bash
创建 redis-cluster：
shell redis-cli --cluster create \ 192.168.255.157:8001 \ 192.168.255.157:8002 \ 192.168.255.157:8003 \ 192.168.255.157:8004 \ 192.168.255.157:8005 \ 192.168.255.157:8006 \ --cluster-replicas 1
RabbitMQ
```shell
端口说明：
4369, 25672 (Erlang发现&集群端口)
5672, 5671 (AMQP端口)
15672 (web管理后台端口)
61613, 61614 (STOMP协议端口)
1883, 8883 (MQTT协议端口)
部署带有管理控制台的RabbitMQ
docker run -d --name rabbitmq -p 5671:5671 -p 5672:5672 -p 4369:4369 -p 25672:25672 -p 15671:15671 -p 15672:15672 -v /opt/rabbitmq:/var/lib/rabbitmq rabbitmq:management ```
