云原生之使用Docker部署Mariadb数据库

一、检查本地系统版本

[root@node axu]# cat /etc/os-release 
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

二、检查docker版本

[root@node ~]# systemctl status docker

三、检查docker状态

[root@node ~]# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
   Active: active (running) since Fri 2022-11-04 09:12:32 CST; 2h 32min ago

Hint: Some lines were ellipsized, use -l to show in full.

四、下载mariadb镜像

[root@node ~]# docker pull mariadb
Using default tag: latest
latest: Pulling from library/mariadb
Digest: sha256:0f04ae6f30c5a3295fb7cc9be5780c15ff21d6028f999b19f5803114c1e8559e
Status: Downloaded newer image for mariadb:latest
docker.io/library/mariadb:latest

五、创建mariadb容器

1.创建数据目录

[root@node ~]# mkdir /data/mariadb
[root@node ~]# cd /data/mariadb/
[root@node mariadb]#

2.创建mariadb容器

[root@node mariadb]# docker run -d   --name my-mariadb --restart always -v /data/mariadb/db:/var/lib/mysql -p 3548:3306 --env MARIADB_USER=admin --env MARIADB_PASSWORD=admin --env MARIADB_ROOT_PASSWORD=admin mariadb:latest
e9b8757eaaf6eb632101a30f9b27c113eaae63e8410a67ed92e76e434c8a81ea

3.查看容器状态

[root@node mariadb]# docker ps
CONTAINER ID   IMAGE            COMMAND                  CREATED          STATUS          PORTS                                           NAMES
e9b8757eaaf6   mariadb:latest   "docker-entrypoint.s…"   36 seconds ago   Up 35 seconds   0.0.0.0:3548->3306/tcp, :::3548->3306/tcp       my-mariadb

六、查看mariadb容器运行日志

[root@node mariadb]# docker logs my-mariadb
