Ubuntu Server12.04+Nginx安装Redmine2.5.1

参考安装文档：
- http://www.redmine.org/projects/redmine/wiki/RedmineInstall#fn1
- http://blog.csdn.net/csfreebird/article/details/18138869

1、安装MySQL

sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev

删除匿名用户

#登陆MySQL数据库
mysql -u root -p
#查看所有用户
mysql> select user,host from mysql.user;
#删除所有空用户（匿名用户）
mysql> delete from mysql.user where user='';
#检查删除结果
mysql> select user,host from mysql.user;
#退出MySQL数据库
mysql> \q

2、安装Nginx

sudo apt-get install -y nginx

3、安装RMagick

sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev

4、安装Ruby

如果存在旧版本Ruby1.8及1.9请先卸载

sudo apt-get remove ruby1.8 ruby1.9

下载、编译Ruby2.0

mkdir /tmp/ruby && cd /tmp/ruby
curl --progress ftp://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p353.tar.gz | tar xz
cd ruby-2.0.0-p353
./configure --disable-install-rdoc
make
sudo make install

国内用户建议更换Ruby Gem源为淘宝源，提高Gem安装速度

sudo gem sources --remove https://rubygems.org/
sudo gem sources -a http://ruby.taobao.org/
#更新缓存
sudo gem sources -u
#查看源，请确保只有 ruby.taobao.org
gem sources -l

安装Bundler Gem

sudo gem install bundler --no-ri --no-rdoc

安装ImageMagick Gem

sudo gem install rmagick -v '2.13.2'

5、下载Redmine2.5.1

#创建Redmine用户
sudo adduser --disabled-login --gecos 'Redmine' redmine
#进入Redmine用户目录
cd /home/redmine
#下载解压源码
curl --progress http://www.redmine.org/releases/redmine-2.5.1.tar.gz | tar xz
#修改文件夹名为redmine
sudo mv redmine-2.5.1 redmine

6、配置MySQL数据库

初始化数据库

#登陆数据库
mysql -u root -p
#创建Redmine数据库
mysql> CREATE DATABASE redmine CHARACTER SET utf8;
#创建Redmine用户，密码'my_password'可以自己设定，后面需要用到
mysql> CREATE USER 'redmine'@'localhost' IDENTIFIED BY 'my_password';
mysql> GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost';

数据库连接配置

#进入Redmine目录
cd /home/redmine/redmine
#复制Redmine数据库默认配置
sudo cp config/database.yml.example config/database.yml

修改配置信息

sudo gedit config/database.yml

找到如下内容

production:
  adapter: mysql2    
  database: redmine    
  host: localhost    
  username: root    
  password: ""    
  encoding: utf8

默认password为空，将其修改为之前设置的MySQL中Redmine用户密码，保存即可。

7、安装Redmine需要的Gem依赖

#进入Redmine目录
cd /home/redmine/redmine
#通过bundle安装Gem依赖
sudo bundle install --without development test

8、Redmine会话配置、数据库初始化及文件系统权限设置

#生成session store
sudo rake generate_secret_token
#创建数据库结构
sudo RAILS_ENV=production rake db:migrate
#插入默认数据，根据提示信息选择指定语言。我这里选择中文，对应选项为zh
sudo RAILS_ENV=production rake redmine:load_default_data
sudo mkdir -p tmp tmp/pdf public/plugin_assets  
sudo chown -R redmine:redmine files log tmp public/plugin_assets
sudo chmod -R 755 files log tmp public/plugin_assets

9、测试

#启动服务用于测试
sudo ruby script/rails server webrick -e production

在浏览器中输入http://localhost:3000即可看到Redmine的站点了
默认账号：admin
默认密码：admin

10、集成unicorn app server

nginx 是一个非常高效的 http server, 而 unicorn 是一个非常高效的 app server。
首先编辑Gemfile文件

sudo gedit Gemfile

打开文件后，在增加unicorn配置，将下面代码插入文件中。（我这里是放到openid组的后面）

# Application server add by armink
group :unicorn do
  gem "unicorn", '~> 4.6.3'
  gem 'unicorn-worker-killer'
end

通过bundle更新Gem依赖，此时会看到unicorn被安装。

sudo bundle install --without development test

增加unicorn配置文件，通过gedit命令打开config/unicorn.rb

sudo gedit config/unicorn.rb

打开空文件后，在里面添加如下内容，我这里端口设置为8082。（里面内容都是参考Gitlab中的unicorn配置修改的）

# Sample verbose configuration file for Unicorn (not Rack)
#
# This configuration file documents many features of Unicorn
# that may not be needed for some applications. See
# http://unicorn.bogomips.org/examples/unicorn.conf.minimal.rb
# for a much simpler configuration file.
#
# See http://unicorn.bogomips.org/Unicorn/Configurator.html for complete
# documentation.
# Use at least one worker per core if you're on a dedicated server,
# more will usually help for _short_ waits on databases/caches.
worker_processes 2
# Since Unicorn is never exposed to outside clients, it does not need to
# run on the standard HTTP port (80), there is no reason to start Unicorn
# as root unless it's from system init scripts.
# If running the master process as root and the workers as an unprivileged
# user, do this to switch euid/egid in the workers (also chowns logs):
# user "unprivileged_user", "unprivileged_group"
# Help ensure your application will always spawn in the symlinked
# "current" directory that Capistrano sets up.
working_directory "/home/redmine/redmine" # available in 0.94.0+
# listen on both a Unix domain socket and a TCP port,
# we use a shorter backlog for quicker failover when busy
listen "/home/redmine/redmine/tmp/sockets/redmine.socket", :backlog => 64
listen "127.0.0.1:8082", :tcp_nopush => true
# nuke workers after 30 seconds instead of 60 seconds (the default)
timeout 30
# feel free to point this anywhere accessible on the filesystem
pid "/home/redmine/redmine/tmp/pids/unicorn.pid"
# By default, the Unicorn logger will write to stderr.
# Additionally, some applications/frameworks log to stderr or stdout,
# so prevent them from going to /dev/null when daemonized here:
stderr_path "/home/redmine/redmine/log/unicorn.stderr.log"
stdout_path "/home/redmine/redmine/log/unicorn.stdout.log"
# combine Ruby 2.0.0dev or REE with "preload_app true" for memory savings
# http://rubyenterpriseedition.com/faq.html#adapt_apps_for_cow
preload_app true
GC.respond_to?(:copy_on_write_friendly=) and
  GC.copy_on_write_friendly = true
# Enable this flag to have unicorn test client connections by writing the
# beginning of the HTTP headers before calling the application.  This
# prevents calling the application for connections that have disconnected
# while queued.  This is only guaranteed to detect clients on the same
# host unicorn runs on, and unlikely to detect disconnects even on a
# fast LAN.
check_client_connection false
before_fork do |server, worker|
  # the following is highly recomended for Rails + "preload_app true"
  # as there's no need for the master process to hold a connection
  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.connection.disconnect!
  # The following is only recommended for memory/DB-constrained
  # installations.  It is not needed if your system can house
  # twice as many worker_processes as you have configured.
  #
  # This allows a new master process to incrementally
  # phase out the old master process with SIGTTOU to avoid a
  # thundering herd (especially in the "preload_app false" case)
  # when doing a transparent upgrade.  The last worker spawned
  # will then kill off the old master process with a SIGQUIT.
  old_pid = "#{server.config[:pid]}.oldbin"
  if old_pid != server.pid
    begin
      sig = (worker.nr + 1) >= server.worker_processes ? :QUIT : :TTOU
      Process.kill(sig, File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
    end
  end
  #
  # Throttle the master from forking too quickly by sleeping.  Due
  # to the implementation of standard Unix signal handlers, this
  # helps (but does not completely) prevent identical, repeated signals
  # from being lost when the receiving process is busy.
  # sleep 1
end
after_fork do |server, worker|
  # per-process listener ports for debugging/admin/migrations
  # addr = "127.0.0.1:#{9293 + worker.nr}"
  # server.listen(addr, :tries => -1, :delay => 5, :tcp_nopush => true)
  # the following is *required* for Rails + "preload_app true",
  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.establish_connection
  # if preload_app is true, then you may also want to check and
  # restart any other shared sockets/descriptors such as Memcached,
  # and Redis.  TokyoCabinet file handles are safe to reuse
  # between any number of forked children (assuming your kernel
  # correctly implements pread()/pwrite() system calls)
end

11、配置Redmine开机自启动

我这里思路和Gitlab是一样的，首先在script文件夹中增加脚本文件对unicorn实现启动、停止等命令控制，再在/etc/init.d文件夹中增加开机自启动脚本，注册启动服务即可。详细过程如下。
增加unicorn控制脚本，通过gedit命令打开script/web

sudo gedit script/web

打开空白文件后，再里面添加如下内容。

#!/usr/bin/env bash
cd $(dirname $0)/..
app_root=$(pwd)
unicorn_pidfile="$app_root/tmp/pids/unicorn.pid"
unicorn_config="$app_root/config/unicorn.rb"
function get_unicorn_pid
{
  local pid=$(cat $unicorn_pidfile)
  if [ -z $pid ] ; then
    echo "Could not find a PID in $unicorn_pidfile"
    exit 1
  fi
  unicorn_pid=$pid
}
function start
{
  bundle exec unicorn_rails -D -c $unicorn_config -E $RAILS_ENV
}
function stop
{
  get_unicorn_pid
  kill -QUIT $unicorn_pid
}
function reload
{
  get_unicorn_pid
  kill -USR2 $unicorn_pid
}
case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  reload)
    reload
    ;;
  *)
    echo "Usage: RAILS_ENV=your_env $0 {start|stop|reload}"
    ;;
esac

设置该脚本文件属性为可执行文件

sudo chmod 755 script/web

增加开机自启动脚本，实现对Redmine中的unicorn开机自启动，通过gedit命令打开/etc/init.d/redmine

sudo gedit /etc/init.d/redmine

在该空白启动脚本文件中加入以下内容

#! /bin/sh

将以下内容拷贝至此空白文件

# RAILS_ENV defines the type of installation that is running.
# Normal values are "production", "test" and "development".
RAILS_ENV="production"

# app_user defines the user that Redmine is run as.
# The default is "redmine".
app_user="redmine"

# app_root defines the folder in which redmine and it's components are installed.
# The default is "/home/$app_user/redmine"
app_root="/home/$app_user/redmine"

# pid_path defines a folder in which the redmine and it's components place their pids.
# This variable is also used below to define the relevant pids for the redmine components.
# The default is "$app_root/tmp/pids"
pid_path="$app_root/tmp/pids"

# socket_path defines the folder in which redmine places the sockets
#The default is "$app_root/tmp/sockets"
socket_path="$app_root/tmp/sockets"

# web_server_pid_path defines the path in which to create the pid file fo the web_server
# The default is "$pid_path/unicorn.pid"
web_server_pid_path="$pid_path/unicorn.pid"

设置此文件属性为可执行文件

chmod 755 /etc/default/redmine

设置Redmine开机自启动

sudo update-rc.d redmine defaults 21

安装过程中遇到问题汇总

问题1：Bundler安装出错

在安装Bundler时，可能会报如下错误：

ERROR:  Loading command: install (LoadError)
    cannot load such file -- openssl
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

原因是没有安装openssl，如果在之前安装了Gitlab默认依赖包里面会包括openssl，否则需要手动安装openssl，方法如下：

#安装libssl-dev
sudo apt-get install libssl-dev
#进入之前解压Ruby2.0源码的目录
cd /tmp/ruby
#进入openssl目录
cd ext/openssl
#编译安装openssl
ruby extconf.rb
make
sudo make install

问题2：ImageMagick安装出错

在进行到 Step 4 - Dependencies installation时，sudo bundle install --without development test命令总是会报ImageMagick安装出错，部分出错日志如下：

ERROR:  Error installing rmagick:
    ERROR: Failed to build gem native extension.
/usr/bin/ruby1.8 extconf.rb
checking for Ruby version >= 1.8.5... yes
checking for gcc... yes
checking for Magick-config... yes
checking for ImageMagick version >= 6.4.9... yes
checking for HDRI disabled version of ImageMagick... yes
checking for stdint.h... yes
checking for sys/types.h... yes
checking for wand/MagickWand.h... no

终于在这里找到答案，前面两个回答对我都没有效果，只有第三个手动安装方式终于尝试安装成功，手动安装ImageMagick步骤如下：

curl --progress ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz | tar xz
#进入ImageMagick源码目录
cd ImageMagick-6.8.8-10
./configure --prefix=/usr/local --with-x=no --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --disable-openmp
make
sudo make install
sudo /sbin/ldconfig /usr/local
sudo ln -f /usr/local/bin/Magick-config /usr/bin/Magick-config
sudo PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ gem install rmagick

安装完成后，再重新执行sudo bundle install --without development test即可完成gems的相关依赖安装。
