Docker安裝MySQL報錯：mysqld failed while attempting to check config…mysqld: Can’t read dir of ‘/etc/mysql/conf.d/’…

[ERROR] [Entrypoint]: mysqld failed while attempting to check config command was: mysqld --verbose --help --log-bin-index=/tmp/tmp.Frnt2oibYI mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory)

1 最初的時候使用如下命令創(chuàng)建容器，但是創(chuàng)建之后通過docker ps查看不到啟動的容器

[root@zxy_master mysql01]# docker run -p 33061:3306 --name mysql01 \
> -v /zxy/apps/docker_mysql/mysql01/conf:/etc/mysql \
> -v /zxy/apps/docker_mysql/mysql01/data:/var/lib/mysql \
> -v /zxy/apps/docker_mysql/mysql01/log:/var/log/mysql \
> -e MYSQL_ROOT_PASSWORD=123456 \
> -d mysql:5.7

2 通過查看該容器的日志，可以看到主要是因為讀取不到/etc/mysql/conf.d/目錄

[root@zxy_master apps]# docker logs -f 358163e8d564
2022-12-20 05:46:26+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 5.7.40-1.el7 started.
2022-12-20 05:46:26+00:00 [ERROR] [Entrypoint]: mysqld failed while attempting to check config
        command was: mysqld --verbose --help --log-bin-index=/tmp/tmp.XeHsvFblmW
        mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory)
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!

3 -v /zxy/apps/docker_mysql/mysql01/conf:/etc/mysql

修改為

-v /zxy/apps/docker_mysql/mysql01/conf:/etc/mysql/conf.d \

[root@zxy_master apps]# docker run -p 33061:3306 --name mysql01 \
> -v /zxy/apps/docker_mysql/mysql01/conf:/etc/mysql/conf.d \
> -v /zxy/apps/docker_mysql/mysql01/data:/var/lib/mysql \
> -v /zxy/apps/docker_mysql/mysql01/log:/var/log/mysql \
> -e MYSQL_ROOT_PASSWORD=123456 \
> -d mysql:5.7

4 再次檢查已經(jīng)啟動成功，報錯原因主要是沒有指定到conf.d目錄，導致容器在啟動的時候找不到該目錄。文章來源地址http://www.zghlxwxcb.cn/news/detail-519658.html

[root@zxy_master apps]# docker ps
