云原生之使用Docker部署Mysql数据库

云原生之使用Docker部署Mysql数据库

一、检查本地系统环境

1.检查系统版本

[root@jeven ~]# 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"

2.检查docker版本

[root@jeven ~]# docker version

  GitCommit:        de40ad0

3.检查docker状态

[root@jeven ~]# systemctl status docker

二、使用Docker部署mysql

1.下载mysql镜像

[root@jeven ~]#  docker pull mysql:5.75.7: Pulling from library/mysql
Digest: sha256:f2ad209efe9c67104167fc609cca6973c8422939491c9345270175a300419f94
Status: Image is up to datefor mysql:5.7
docker.io/library/mysql:5.7

2.创建数据目录

[root@jeven ~]# mkdir -p /data/mysql/db[root@jeven ~]# cd /data/mysql/[root@jeven mysql]# 

3.创建mysql容器

[root@jeven mysql]# docker run -d --name my-mysql --restart always -v /data/mysql/db:/var/lib/mysql -p 3666:3306 -e MYSQL_ROOT_PASSWORD=admin -e MYSQL_DATABASE=test  mysql:5.7
09a6697c529a1eb3e2dfe3bbaf6923ec81028eb7233b07b163df9dc8f9bc080b

4.查看mysql容器状态

[root@jeven mysql]# docker ps
CONTAINER ID   IMAGE               COMMAND                  CREATED          STATUS          PORTS                                                  NAMES
09a6697c529a   mysql:5.7           "docker-entrypoint.s…"56 seconds ago   Up 53 seconds   33060/tcp, 0.0.0.0:3666->3306/tcp, :::3666->3306/tcp   my-mysql

三、进入数据库内

1.进入mysql容器

[root@jeven mysql]# docker exec -it my-mysql /bin/bash
root@09a6697c529a:/# 

2.进入mysql数据库


root@09a6697c529a:/# mysql -h 127.0.0.1 -P3306 -uroot -padmin
mysql: [Warning] Using a password on the command line interface can be insecure.

四、Linux系统安装Mysql

1.下载官方mysql的rpm包

[root@server ~]# wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

3.修改mysql-community.repo文件

sed-i"s/gpgcheck=1/gpgcheck=0/g" mysql-community.repo

4.安装mysql

yum -yinstall mysql-community-server

5.修改my.conf

[root@server yum.repos.d]# grep  skip /etc/my.cnf
skip-grant-tables

6.启动mysql服务

[root@server yum.repos.d]# systemctl start mysqld[root@server yum.repos.d]# systemctl enable mysqld

7.查看mysql状态

[root@server yum.repos.d]# systemctl status mysqld
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2022-11-24 18:05:02 CST; 29s ago
