容器化部署mariadb数据库

compose文档：Compose specification | Docker Documentation

容器地址及文档：Docker Hub

 部署环境依赖

1.docker-ce安装

 a.卸载老版本的docker

sudo yum remove docker \
                docker-client \
                docker-client-latest \
                docker-common \
                docker-latest \
                docker-latest-logrotate \
                docker-logrotate \
                docker-engine

b.设置容器仓库

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

c.安装容器引擎，默认安装最新版本

sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

d.启动容器

systemctl start docker

2.可以通过国内镜像进行加速，本次使用的是阿里云镜像加速

阿里云容器加速访问网址：阿里云登录 - 欢迎登录阿里云，安全稳定的云计算服务平台 

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://0cbolbbb.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

 3.安装docker-compose

curl -L https://get.daocloud.io/docker/compose/releases/download/v2.10.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

参考文档编写docker-compose文件

1.创建数据目录

mkdir /data/mariadb -pv
cd /data/mariadb

2.创建 docker-compose.yml文件，内容如下

cd /data/mariadb/
vi docker-compose.yml

version: '3.2'


services:

  mariadb:
    image: bitnami/mariadb:10.7.3
    container_name: mariadb 
    restart: always
    environment:
            - MARIADB_ROOT_PASSWORD=rootIPD.xx2.19
            - MARIADB_DATABASE=flyapps
            - MARIADB_USER=flyuser
            - MARIADB_PASSWORD=KGzKjZpWBp4R4RSa
              #- ALLOW_EMPTY_PASSWORD=yes
            - MARIADB_ENABLE_SLOW_QUERY=1
            - MARIADB_LONG_QUERY_TIME=3
            - MARIADB_SKIP_TEST_DB=yes
            - MARIADB_EXTRA_FLAGS=--max-connect-errors=3000 --max_connections=30000
    ports:
      - 3306:3306

    volumes:
       - /etc/localtime:/etc/localtime:ro
       - ./data/mariadb:/bitnami/mariadb/data
       - ./data/logs/mariadb:/data/logs/mariadb
       - ./server.cnf:/opt/bitnami/mariadb/conf/my_custom.cnf:ro

注意： mariadb环境变量设置，请参考官方文档Docker Hub

3.数据库配置文件 server.cnf

cd /data/mariadb/
vi server.cnf

 内容如下：

#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#

 启动容器服务

需要提前创建好容器所需目录和授权

cd /data/mariadb/
mkdir -pv data/{mariadb,logs/mariadb}
chown 1001.1001 -R data/{mariadb,logs/mariadb}

# 根据需求进行启动
#docker-compose up   # 前端运行启动

docker-compose up -d # 后台启动,一般执行该命令后台运行

# 停止并删除容器，因为使用数据挂载，因此不会删除数据
docker-compose down

查看容器状态

docker-compose ps

 查看容器运行日志 docker-compose logs

查看mariadb服务日志，需要打开挂载目录进行查看

cd /data/mariadb/data/logs/mariadb

连接测试，输入配置文件内指定的用户

 若有配置服务开机启动，需要设置docker服务开机启动即可

systemctl enable docker
