基本上安裝過程都可以透過redmine的how to查看：
1.http://martin-denizet.com/install-redmine-2-5-x-git-subversion-ubuntu-14-04-apache2-rvm-passenger/
2.http://www.redmine.org/projects/redmine/wiki/HowToss
需要特別注意的是，我在安裝過程中沒有替網站加上ssl，裝完後去用，其實也是ok的。
其中要注意的是config/database.yml裡面的檔案：
production: adapter: mysql2 database: redmine host: localhost username: redmine password: "my_password" encoding: utf8
上述的username跟password，記得改成進入mysql新增使用時的帳號密碼。然後 /etc/apache2/conf-available/passenger.conf的檔案在執行完passenger-install-apache2-module這行指令後，會顯示給你，加上去即可。記得將你自己的domain name指到/opt/redmine/current/public這個目錄下。
另外在sites-avalible裡新增一個.conf檔案，把redmine安裝過程裡說要加的都加一加。
ServerName redmine.domain.com
ServerAdmin admin@domain.com
ServerName redmine.domain.com

# Keep the spawners alive, which speeds up spawning a new Application
# listener after a period of inactivity at the expense of memory.
RailsAppSpawnerIdleTime 3600
# Additionally keep a copy of the Rails framework in memory. If you're
# using multiple apps on the same version of Rails, this will speed up
# the creation of new RailsAppSpawners. This isn't necessary if you're
# only running one or 2 applications, or if your applications use
# different versions of Rails.

# Just in case you're leaking memory, restart a listener

# only check for restart.txt et al up to once every 5 seconds,
# instead of once per processed request
PassengerStatThrottleRate 5
# If user switching support is enabled, then Phusion Passenger will by default run the web application as the owner if the file config/environment.rb (for Rails apps) or config.ru (for Rack apps). This option allows you to override that behavior and explicitly set a user to run the web application as, regardless of the ownership of environment.rb/config.ru.
PassengerUser www-data
PassengerGroup www-data
# By default, Phusion Passenger does not start any application instances until said web application is first accessed. The result is that the first visitor of said web application might experience a small delay as Phusion Passenger is starting the web application on demand. If that is undesirable, then this directive can be used to pre-started application instances during Apache startup.

註：SSL相關的可以跳過。
其他應該都沒什麼大問題了，有空再來研究加上SSL。
