docker 搭建mysql

本文主要是介绍docker 搭建mysql，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！

docker 搭建mysql

我们可以先通过docker search mysql查找镜像，这里直接拉取官方的镜像

[root@localhost docker]# docker pull mysql

等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为mysql的镜像

[root@localhost docker]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/php       7.4-fpm             11d1c5c37e37        2 weeks ago         405 MB
docker.io/mysql     latest              0627ec6901db        4 weeks ago         556 MB
docker.io/nginx     latest              62d49f9bab67        5 weeks ago         133 MB
docker.io/redis     6.0                 e13c690ca406        5 weeks ago         104 MB

配置宿主机的mysql配置文件

[root@localhost docker]# vim /etc/my.cnf

[client]
port		= 3306
socket		= /tmp/mysql.sock

[mysqld]
secure_file_priv=/var/lib/mysql
port		= 3306
socket		= /tmp/mysql.sock
datadir = /usr/local/mysql/data
default_storage_engine = InnoDB

key_buffer_size = 32M
max_allowed_packet = 100G
table_open_cache = 128
sort_buffer_size = 768K
net_buffer_length = 4K

read_rnd_buffer_size = 256K

innodb_lock_wait_timeout = 50
innodb_max_dirty_pages_pct = 90
innodb_read_io_threads = 1
innodb_write_io_threads = 1

[mysqldump]

max_allowed_packet = 500M

[mysql]

[myisamchk]

使用php镜像开启php-frm应用容器

[root@localhost docker]# docker run -p 3306:3306 -d --name mysql -v /etc/my.cnf:/etc/mysql/my.cnf --privileged=true -e MYSQL_ROOT_PASSWORD=root mysql

-p 3306:3306 :将容器的3306端口映射到主机的3306端口
-d 后台运行(守护进程)
--name mysql：将容器命名为mysql
-v 将主机中的mysql配置挂载到容器的/etc/mysql/my.cnf

进入容器，连接mysql配置一个自己的用户，用于项目使用。

[root@localhost docker]# docker exec -it mysql bash
root@0ead771c95b4:/#

#连接mysql，密码就是我们在构建容器时镜像设置的MYSQL_ROOT_PASSWORD参数值
root@0ead771c95b4:/# mysql -uroot -p
Enter password:

在本地使用Navicat测试mysql：
