本篇文章给大家介绍如何使用 Docker 部署在企业工作中常用的中间件服务。
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
设置宿主机 80 端口和容器的 80 端口映射，以及数据卷目录挂载与容器的配置文件所在目录映射。一个是 Nginx 的主页还有一个是服务器配置文件。
Tomat
shell docker run -d -p 8080:8080 \ -v /opt/tomcat-server:/usr/local/tomcat/webapps/ROOT \ tomcat:9.0
设置宿主机端口 8080 端口和容器 8080 端口映射，访问宿主机 IP 地址加上 8080 端口就可以查看 Tomcat 主页。
-v 参数设置的是 Tomcat 容器的 webapps 和宿主机的目录映射关系，在宿主机的目录下添加 war 包就可以正常访问你开发的 web app 了。
MySQL
单机部署
MySQL 长期支持版本有 5.7 和 8.0，这里演示的是 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
若要使用 MySQL 内置的客户端访问，输入以下命令：
```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)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> ```
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
Welcome to the MariaDB monitor. Commands end with ; or \g. Your MySQL connection id is 7 Server version: 5.7.37 MySQL Community Server (GPL)

MySQL [(none)]> show databases; +--------------------+ | Database | +--------------------+ | informationschema | | mysql | | performanceschema | | sys | +--------------------+ 4 rows in set (0.00 sec) ```
主从复制集群部署
部署主节点
shell docker run -d -p 3306:3306 \ --name mysql-master \ -v /opt/mysql-master/log:/var/log/mysql \ -v /opt/mysql-master/data:/var/lib/mysql \ -v /opt/mysql-master/conf:/etc/mysql \ -e MYSQL_ROOT_PASSWORD=root \ mysql:5.7
配置主节点
```shell
vim /opt/mysql-master/conf/my.cnf
cat /opt/mysql-master/conf/my.cnf
[client] default-character-set=utf8
[mysql] default-character-set=utf8
[mysqld] initconnect='SET collationconnection = utf8unicodeci' initconnect='SET NAMES utf8' character-set-server=utf8 collation-server=utf8unicode_ci skip-character-set-client-handshake skip-name-resolve
serverid=1 log-bin=mysql-bin read-only=0 binlog-do-db=kubemsbtest
replicate-ignore-db=mysql replicate-ignore-db=sys replicate-ignore-db=informationschema replicate-ignore-db=performanceschema ```
部署从节点
shell docker run -d -p 3307:3306 \ --name mysql-slave \ -v /opt/mysql-slave/log:/var/log/mysql \ -v /opt/mysql-slave/data:/var/lib/mysql \ -v /opt/mysql-slave/conf:/etc/mysql \ -e MYSQL_ROOT_PASSWORD=root \ --link mysql-master:mysql-master \ mysql:5.7
配置从节点
```shell
vim /opt/mysql-slave/conf/my.cnf
cat /opt/mysql-slave/conf/my.cnf
[client] default-character-set=utf8
[mysql] default-character-set=utf8
[mysqld] initconnect='SET collationconnection = utf8unicodeci' initconnect='SET NAMES utf8' character-set-server=utf8 collation-server=utf8unicode_ci skip-character-set-client-handshake skip-name-resolve

集群配置
配置主节点
```shell
mysql -h 192.168.255.157 -uroot -proot -P 3306

MySQL [(none)]> ```
```shell
授权
MySQL [(none)]> grant replication slave on . to 'backup'@'%' identified by '123456'; ```
```shell
重启容器，使用配置生效
docker restart mysql-master
查看状态
MySQL [(none)]> show master status\G ******** 1. row ******** File: mysql-bin.000001 Position: 154 BinlogDoDB: kubemsbtest BinlogIgnoreDB: ExecutedGtid_Set: 1 row in set (0.00 sec) ```

MySQL [(none)]> start slave;
查看从节点状态
MySQL [(none)]> show slave status\G ```
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 ```
