如果需要覆盖默认的Redmine配置，最简单的方式就是复制config/configuration.yml.example为config/configuration.yml，然后修改这个配置文件。修改完需要重启Redmine服务才能生效。

# Configuration of SCM executable command.
# Absolute path (e.g. /usr/local/bin/hg) or command name (e.g. hg.exe, bzr.exe)

# Examples:
# scm_subversion_command: svn                                       # (default: svn)
# scm_mercurial_command:  C:\Program Files\TortoiseHg\hg.exe        # (default: hg)
# scm_git_command:        /usr/local/bin/git                        # (default: git)
# scm_cvs_command:        cvs                                       # (default: cvs)

scm_mercurial_command:
scm_git_command:
scm_cvs_command:
scm_bazaar_command:

附件存储路径设置

# Absolute path to the directory where attachments are stored.
# The default is the 'files' directory in your Redmine instance.
# Your Redmine instance needs to have write permission on this
# directory.
# Examples:
# attachments_storage_path: /var/redmine/files
# attachments_storage_path: D:/redmine/files
attachments_storage_path:

日志功能配置

复制config/additional_environment.rb.example 为 config/additional_environment.rb 并增加如下几行

#Logger.new(PATH,NUM_FILES_TO_ROTATE,FILE_SIZE)
config.logger = Logger.new(config.log_path, 2, 1000000)
config.logger.level = Logger::INFO

备份

备份应该包含：数据备份和附件备份


简单的日常备份脚本如下（假设你使用的是mysql数据库）：

# Database
/usr/bin/mysqldump -u <username> -p<password> <redmine_database> | gzip > /path/to/backup/db/redmine_`date +%y_%m_%d`.gz

# Attachments
rsync -a /path/to/redmine/files /path/to/backup/files
