如何使用Docker部署mysql数据库

如何使用Docker部署mysql数据库

一、检查系统版本

[root@node ~]# 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://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"登录后复制

二、检查docker状态

1.检查docker版本

[root@node ~]# [root@node ~]# docker versionClient: Docker Engine - Community Version: 20.10.17 API version: 1.41 Go version: go1.17.11 Git commit: 100c701 Built: Mon Jun 6 23:05:12 2022 OS/Arch: linux/amd64 Context: default Experimental: trueServer: Docker Engine - Community Engine: Version: 20.10.17 API version: 1.41 (minimum version 1.12) Go version: go1.17.11 Git commit: a89b842 Built: Mon Jun 6 23:03:33 2022 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.6.6 GitCommit: 10c12954828e7c7c9b6e0ea9b0c02b01407d3ae1 runc: Version: 1.1.2 GitCommit: v1.1.2-0-ga916309 docker-init: Version: 0.19.0 GitCommit: de40ad0登录后复制

2.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 Mon 2022-10-31 03:28:51 CST; 3 days ago Docs: https://docs.docker.com Main PID: 11884 (dockerd) Tasks: 32 Memory: 3.4G CGroup: /system.slice/docker.service ├─11884 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock ├─89868 /usr/bin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 8100 -container-ip 172.17.0.2 -container-port 8100 └─89875 /usr/bin/docker-proxy -proto tcp -host-ip :: -host-port 8100 -container-ip 172.17.0.2 -container-port 8100Nov 03 01:23:55 node dockerd[11884]: time="2022-11-03T01:23:55.090581806+08:00" level=info msg="ignoring event" container=d9f4cabef3539e...kDelete"Nov 03 01:25:19 node dockerd[11884]: time="2022-11-03T01:25:19.911516515+08:00" level=info msg="ignoring event" container=e7556e1f3cd741...kDelete"Nov 03 01:25:20 node dockerd[11884]: time="2022-11-03T01:25:20.514390808+08:00" level=info msg="ignoring event" container=cb68026ad986be...kDelete"Nov 03 01:25:20 node dockerd[11884]: time="2022-11-03T01:25:20.907601037+08:00" level=info msg="ignoring event" container=3fccd6f474f242...kDelete"Nov 03 01:28:08 node dockerd[11884]: time="2022-11-03T01:28:08.318850188+08:00" level=info msg="ignoring event" container=c40d1656d49185...kDelete"Nov 03 01:29:44 node dockerd[11884]: time="2022-11-03T01:29:44.687790759+08:00" level=info msg="ignoring event" container=aaa5856375e071...kDelete"Nov 03 01:29:49 node dockerd[11884]: time="2022-11-03T01:29:49.913701227+08:00" level=info msg="ignoring event" container=4df40876d4fdc5...kDelete"Nov 03 01:29:50 node dockerd[11884]: time="2022-11-03T01:29:50.273656357+08:00" level=info msg="Layer sha256:7c05c40a224c88646a3c06ee539...aned up"Nov 03 01:29:50 node dockerd[11884]: time="2022-11-03T01:29:50.341692050+08:00" level=info msg="Layer sha256:7c05c40a224c88646a3c06ee539...aned up"Nov 03 01:29:50 node dockerd[11884]: time="2022-11-03T01:29:50.411279167+08:00" level=info msg="Layer sha256:7c05c40a224c88646a3c06ee539...aned up"Hint: Some lines were ellipsized, use -l to show in full.登录后复制

四、下载mysql镜像

[root@node ~]# docker pull mysql:5.75.7: Pulling from library/mysqlDigest: sha256:f2ad209efe9c67104167fc609cca6973c8422939491c9345270175a300419f94Status: Image is up to date for mysql:5.7docker.io/library/mysql:5.7登录后复制

五、创建mysql容器

1.创建数据目录

[root@node ~]# mkdir -p /data/mysql[root@node ~]# cd /data/mysql/[root@node mysql]# ls登录后复制

2.运行mysql容器

[root@node mysql]# docker run -d --name mysql_01 --restart always -v /data/mysql/db:/var/lib/mysql -p 3541:3306 -e MYSQL_ROOT_PASSWORD=admin -e MYSQL_DATABASE=data mysql:5.7aa36de70b1ae62ed3e123c504e6a6ad28aae1c399ca94fd5c507d3ed5c1a51f4登录后复制

3.查看mysql容器状态

[root@node mysql]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESaa36de70b1ae mysql:5.7 "docker-entrypoint.s…" 2 seconds ago Up 2 seconds 33060/tcp, 0.0.0.0:3541->3306/tcp, :::3541->3306/tcp mysql_01登录后复制

4.查看mysql容器运行日志
