数据库初始化失败！解决方法一种

[yexing159]

检查docker ps -a，发现数据库对应的容器mariadb 处于restart状态：

root@# docker ps -a
CONTAINER ID   IMAGE                             COMMAND                  CREATED        STATUS                          PORTS                                       NAMES

检查mariadb的日志 docker logs mariadb

2023-10-19 06:14:08+00:00 [Note] [Entrypoint]: Entrypoint script for MariaDB Server 1:10.7.3+maria~focal started.
2023-10-19 06:14:08+00:00 [Note] [Entrypoint]: Switching to dedicated user 'mysql'
2023-10-19 06:14:08+00:00 [Note] [Entrypoint]: Entrypoint script for MariaDB Server 1:10.7.3+maria~focal started.
2023-10-19 06:14:08+00:00 [ERROR] [Entrypoint]: mariadbd failed while attempting to check config
        command was: mariadbd --verbose --help --log-bin-index=/tmp/tmp.4r6Wld3MVt
        mariadbd: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 13 "Permission denied")
Fatal error in defaults handling. Program aborted

可以清晰看到，启动失败原因为mysql/conf.d 文件夹权限不对，无法read

再看cmd源码，数据库初始化失败的检查条件为：
while [ ! -f "${cur_path}/docker/mysql/data/$(env_get DB_DATABASE)/db.opt" ]; do

即可以确定，docker数据库容器mariadb启动失败，导致无法挂载容器目录、认为数据库初始化失败
根因为mysql/conf.d 目录权限设置有问题。
cmd脚本中是将该目录权限设置为775，但估计各种环境差异性，某些环境就会出现权限问题

解决方法：
首先检查mariadb的所需的权限id是多少，如下为999：

# docker run -it --rm --user mysql:mysql mariadb:10.7.3 id
uid=999(mysql) gid=999(mysql) groups=999(mysql)

docker images查看你的mariadb版本是多少，对应吧 10.7.3 这段改成那个版本
然后修改./docker/mysql 所有文件权限
chown -R 999:999 *

再去install就正常了
