需要先准备一个数据库redmine ，编码为utf8 ，utf8_unicode_ci ,不要使用utf8mb4
新建用户redmine密码为redmine,并授权redmine库所有权限给redmine
create user 'redmine'@'%' identified by 'redmine'; -- 创建用户
grant all on redmine.* to redmine -- 授权 拉镜像
docker pull redmine 创建目录
mkdir /home/dockerdata/data
mkdir /home/dockerdata/files
mkdir /home/dockerdata/themes
mkdir /home/dockerdata/plugins
mkdir /home/dockerdata/app 运行
docker run -d \
-e REDMINE_DB_MYSQL=192.168.1.31 \
-e REDMINE_DB_PORT=3306 \
-e REDMINE_DB_DATABASE=redmine \
-e REDMINE_DB_USERNAME=redmine \
-e REDMINE_DB_PASSWORD=redmine \
-p 3000:3000 --restart=always \
-v /home/dockerdata/data:/home/redmine/data \
-v /home/dockerdata/files:/usr/src/redmine/files \
-v /home/dockerdata/themes:/usr/src/redmine/public/themes \
-v /home/dockerdata/plugins:/usr/src/redmine/plugins \
-v /home/dockerdata/app:/usr/src/redmine/app \
--name redmine \
