docker-compose完成mysql8.0+环境搭建

news2024/11/25 3:04:06

1、准备my.cnf文件到指定目录（和基础的增加了一个default_authentication_plugin=mysql_native_password 的身份验证插件配置信息）
原因：官方提到：在这里插入图片描述
该方式可以解决：Authentication plugin ‘caching_ sha2_password‘ cannot be loaded:等类似问题；
2、搭建docker环境 docker compose环境
3、创建需要挂载mysql数据的目录数据目录，日志目录，配置目录
4、将my.cnf放到和mysql容器内匹配的地方
5、创建docker-compose.yml文件
6、启动 docker compose up -d

ps：我使用sequelpro该mysql连接工具进行连接的时候，又出现了查询不到databases的情况，换一个客户端就可以了

my.conf文件(已经修改配置，可以直接使用)

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

# Remove leading # to revert to previous value for default_authentication_plugin,
# this will increase compatibility with older clients. For background, see:
