Step-by-Step Guide to Installing Docker, MySQL, and Apollo Services on CentOS

This article presents a comprehensive, command‑by‑command guide for installing a specific Docker version, preparing MySQL data directories, pulling MySQL and Apollo images, and configuring Apollo Config Service, Admin Service, and Portal Server on a CentOS machine.

Install Docker and required utilities:

yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum list docker-ce --showduplicates | sort -r

yum -y install docker-ce-18.06.3.ce-3.el7

systemctl start docker

Create MySQL data directories and set ownership:

mkdir /data/mysql/conf/ -pv

mkdir /data/mysql/logs

mkdir /data/mysql/mysql

chown -R mysql.mysql /data/mysql

Pull the MySQL image and run the container with volume mounts and root password:

docker pull mysql:8.0.19

docker run -d --name mysql8.0.19 --restart always -p3306:3306 \
  -v /data/mysql/conf/my.cnf:/etc/mysql/my.cnf \
  -v /data/mysql/logs:/logs \
  -v /data/mysql/mysql:/var/lib/mysql \
  -e MYSQL_ROOT_PASSWORD=123456 \
  mysql:8.0.19

Enter the MySQL container and import the Apollo SQL scripts:

docker exec -it 3b0fd3fcbae2 /bin/bash

cd /var/lib/mysql

mysql> source /var/lib/mysql/mysql/apolloportaldb.sql

mysql> source /var/lib/mysql/mysql/apolloconfigdb.sql

Pull and run the Apollo Config Service container with required environment variables:

docker pull apolloconfig/apollo-configservice

docker run -d \
  --name apollo-configservice \
  --net=host \
  -v /tmp/logs:/opt/logs \
  -e SPRING_DATASOURCE_URL="jdbc:mysql://192.168.20.57:3306/ApolloConfigDB?characterEncoding=utf8" \
  -e SPRING_DATASOURCE_USERNAME=root \
  -e SPRING_DATASOURCE_PASSWORD=123456 \
  apolloconfig/apollo-configservice

Pull and run the Apollo Admin Service container (using the same configuration as Config Service):

docker pull apolloconfig/apollo-adminservice

docker run -d --name apollo-adminservice \
  --net=host \
  -v /tmp/logs:/opt/logs \
  -e SPRING_DATASOURCE_URL="jdbc:mysql://192.168.20.57:3306/ApolloConfigDB?characterEncoding=utf8" \
  -e SPRING_DATASOURCE_USERNAME=root \
  -e SPRING_DATASOURCE_PASSWORD=123456 \
  apolloconfig/apollo-configservice

Pull and run the Apollo Portal Server container with additional environment variables for portal configuration:

docker pull apolloconfig/apollo-portal

docker run -d --name apollo-portal \
  --net=host \
  -v /tmp/logs:/opt/logs \
  -e SPRING_DATASOURCE_URL="jdbc:mysql://192.168.20.57:3306/ApolloPortalDB?characterEncoding=utf8" \
  -e SPRING_DATASOURCE_USERNAME=root \
  -e SPRING_DATASOURCE_PASSWORD=123456 \
  -e APOLLO_PORTAL_ENVS=dev \
  -e DEV_META=http://192.168.20.57:8080 \
  apolloconfig/apollo-portal

Verify the services are running:

netstat -nltp

docker ps -a
