Docker 安装 MySQL、Redis

2022/9/1 2:22:59

本文主要是介绍Docker 安装 MySQL、Redis,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

1 Docker 中安装 Redis

1.1 创建目录

在硬盘上创建 redis 的数据目录:

mkdir -p /Users/yygnb/dockerMe/redis/data

为该目录添加权限:

chown 200 -R /Users/yygnb/dockerMe/redis

1.2 拉取镜像

搜索镜像:

docker search redis

搜索结果:

image-20220828234855466

拉取官方镜像:

docker pull redis

1.3 启动容器

映射端口 6379 和 data 目录,启动容器:

docker run -itd -p 6379:6379 \
           -v /Users/yygnb/dockerMe/redis/data:/data \
           --restart always \
           --name redis \
           redis

1.4 查看 Redis 状态

docker ps -a | grep redis

Redis 容器运行后,可以通过 RDM 等客户端工具尝试连接。

2 Docker 中安装 MySQL

2.1 创建目录

在硬盘上分别创建 conf(配置文件目录)、data(数据文件目录)、logs(日志文件目录):

mkdir -p /Users/yygnb/dockerMe/mysql/conf /Users/yygnb/dockerMe/mysql/logs /Users/yygnb/dockerMe/mysql/data

为上面三个目录添加权限:

chown 200 -R /Users/yygnb/dockerMe/mysql

2.2 拉取镜像

docker search mysql

搜索结果:

image-20220828233034166

拉取官方镜像:

docker pull mysql

2.3 创建配置文件

进入上面创建的 mysql/conf 目录下,创建配置文件 my.cnf

cd /Users/yygnb/dockerMe/mysql/conf
touch my.cnf
vi my.cnf

配置文件 my.cnf 内容如下:

# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

[client]
default-character-set=utf8mb4

[mysql]
default-character-set=utf8mb4
 
[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
max_connections=10000
default-time_zone='+8:00'
character-set-client-handshake=FALSE
character_set_server=utf8mb4
collation-server=utf8mb4_general_ci
init_connect='SET NAMES utf8mb4 COLLATE utf8mb4_general_ci'
 
# Custom config should go here
!includedir /etc/mysql/conf.d/

2.4 启动容器

启动容器,指定3306 端口映射和上面的三个目录映射,同时也指定 MySQL root 账户的密码为 Mysql.123

docker run --name mysql \
  --restart=always \
  -p 3306:3306  \
  -v /Users/yygnb/dockerMe/mysql/conf/my.cnf:/etc/mysql/my.cnf \
  -v /Users/yygnb/dockerMe/mysql/data:/var/lib/mysql \
  -v /Users/yygnb/dockerMe/mysql/logs:/logs \
  --privileged=true \
  -e MYSQL_ROOT_PASSWORD=Mysql.123 \
  -d mysql:latest

2.5 查看 MySQL 状态

docker ps | grep mysql

2.6 修改 MySQL 权限

容器启动后,可以进入容器修改 MySQL 的一些权限,使得外部可以连接。

进入容器:

docker exec -it mysql /bin/bash

登录 MySQL:

mysql -u root -p

输入上面设置的密码 Mysql.123后便在命令行中进入了 MySQL。

依次执行下列 SQL 语句,修改权限:

use mysql; 

update user set authentication_string='' where user='root';

alter user 'root'@'%' IDENTIFIED BY 'Mysql.123';

grant all privileges on *.* to 'root'@'%' with grant option;

flush privileges;

全部执行完毕后,可以尝试使用 MySQL Workbench 或 IDEA 或 Navicat 连接 MySQL。

MySQL 8 的 JDBC 连接串一般格式为:

jdbc:mysql://127.0.0.1:3306/db_name?useUnicode=true&characterEncoding=utf8&useSSL=true

驱动为:

com.mysql.cj.jdbc.Driver
