Install redmine

Ohhh, instead of manually installing, actually you could find a third-party full installer at bitnami website. 

# You need to install devel version in order to build for ImageMagick.
yum install -y ImageMagick-devel

LDAP

Ref. Login attributes I would like to use "cn" instead of "dn".
And see this Ref: On the fly user creation is a must. Without it you need users in Redmine magically that match the LDAP server - No way! 

Name: an arbitrary name for the directory
Host: the LDAP host name
Port: the LDAP port (default is 389)
LDAPS: check this if you want or need to use LDAPS to access the directory
Account: enter a username that has read access to the LDAP , otherwise leave this field empty if your LDAP can be read anonymously (Active Directory servers generally do not allow anonymous access)
Password: password for the account
Base DN: the top level DN of your LDAP directory tree
Login attribute: enter the name of the LDAP attribute that will be used as the Redmine username.

Storage

Attachment storage settings. You can set a path where Redmine attachments will be stored which is different from the default 'files' directory of your Redmine instance using the attachments_storage_path setting. Default "attachments_storage_path: pathto/redmine/files"

Log

Redmine defaults to a log level of :info, writing to the log subdirectory "pathto/redmine/log". Depending on site usage, this can be a lot of data so to avoid the contents of the logfile growing without bound, consider rotating them, either through a system utility like logrotate or via the config/additional_environment.rb file.

To use the latter, copy config/additional_environment.rb.example to config/additional_environment.rb and add the following lines. Note that the new logger defaults to a high log level and hence has to be explicitly set to info. 

#Logger.new(PATH,NUM_FILES_TO_ROTATE,FILE_SIZE)
config.logger = Logger.new('/path/to/logfile.log', 2, 1000000)
config.logger.level = Logger::INFO

Backup

# 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

Autostart redmine on CentOS

Ref. You shouldn't use webrick in production, have a look at passenger if you also use apache on that server, mongrel is also an alternative that doesn't require apache.

Enable email

Ref. 

config.action_mailer.delivery_method = :sendmail
# Defaults to:
# config.action_mailer.sendmail_settings = {
#   location: '/usr/sbin/sendmail',
#   arguments: '-i -t'
# }

Install redmine to apache

Wcf Warning: this may run slowly. Consider to use fastcgi. Ref. Ref2.

  1. gem install passenger. passenger-install-apache2-module. Restart apache.
  2. Install redmine and make sure the webrick server is running successfully.
  3. cp public/dispatch.cgi.example to public/dispatch.cgi.
    1. Add in dispatch.cgi the line: #!/usr/bin/ruby.
    2. Change the require line to an absolute path:
    3. Make sure the file has permision: 755.
  4. Update the config/environment.rb file to force the rails environment to production. Simply uncomment this line at the start of the file: ENV['RAILS_ENV'] ||= 'production'
  5. Add to apache conf file. See below.
  6. Don't forget to bind to the port: Listen *:3000
  7. chown -R apache:apache files log tmp vendor. 
  8. cp dispatch.cgi.example dispatch.cgi
cp dispatch.fcgi.example dispatch.fcgi
cp dispatch.rb.example dispatch.rb
  9. Edit .htaccess file for CGI dispatch configuration: cd pathTo/redmine/public && cp htaccess.fcgi.example .htaccess
