Apache下Redmine2.6配置，请参考：http://blog.linuxeye.com/405.html
CentOS6.6下安装Redmine2.6+MySQL5.6+Nginx,教程如下：
1. 初始环境
系统版本：CentOS-6.6-x86_64-minimal.iso
安装LNMP，参考《lnmp一键安装包》；修改options.conf，home_dir=/data/wwwroot
2. ruby安装
cd lnmp/src
wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.5.tar.gz
tar xzf ruby-2.1.5.tar.gz
cd ruby-2.1.5
./configure --prefix=/usr/local/ruby
make && make install
cd ..
添加到环境变量
vi /etc/profile
export PATH=/usr/local/ruby/bin:$PATH
. /etc/profile
查看ruby版本号
# ruby -v
ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux]
3. 安装rails
#安装gem
wget http://production.cf.rubygems.org/rubygems/rubygems-2.4.5.tgz
tar xzf rubygems-2.4.5.tgz
cd rubygems-2.4.5
ruby setup.rb
cd ..
提示：gem是一种文件组织的包，一般的ruby的很多插件都有由这种各种的包提供。
# gem -v
2.4.5
# which gem
/usr/local/ruby/bin/gem
由于国内网络原因（你懂的），导致rubygems.org存放 Amazon S3上面的资源文件间歇性连接失败。所以你会与遇到gem install rack或bundle install的时候半天没有响应，具体可以用gem install rails -V来查看执行过程。下面替换成淘宝的GEM镜像站：
# gem sources -l
*** CURRENT SOURCES ***
https://rubygems.org/
# gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources
# gem sources -a https://ruby.taobao.org/
https://ruby.taobao.org/ added to sources
# gem sources -l
*** CURRENT SOURCES ***
https://ruby.taobao.org/
Redmine需要考虑Ruby版本兼容性问题，请参考：Installing Redmine
| Redmine version | Supported Ruby versions | Rails version used |
| current trunk | ruby 1.9.3, 2.0.0, 2.1, jruby-1.7.6 | Rails 4.1 |
| trunk < r13482 | ruby 1.8.7, 1.9.2, 1.9.3, 2.0.0, 2.1, jruby-1.7.6 | Rails 3.2 |
| 2.5, 2.6 | ruby 1.8.7, 1.9.2, 1.9.3, 2.0.0, 2.1, jruby-1.7.6 | Rails 3.2 |
| 2.4 | ruby 1.8.7, 1.9.2, 1.9.3, 2.0.0, jruby-1.7.6 | Rails 3.2 |
Redmine选择安装2.6版本，因此rails安装3.2版本
gem install rails -v=3.2
# rails -v
Rails 3.2.19
4. 安装redmine2.6
wget http://www.redmine.org/releases/redmine-2.6.1.tar.gz
tar xzf redmine-2.6.1.tar.gz -C /data/wwwroot
mv /data/wwwroot/redmine{-2.6.1,}
创建redmine数据库
cd /data/wwwroot/redmine
# mysql -uroot -p
mysql> create database redmine;
make sure to install the C bindings for Ruby that dramatically improve performance. You can get them by running gem install mysql2.
配置Redmine的database.yml
cd /data/wwwroot/redmine/config
cp database.yml.example database.yml
cat database.yum #修改对应数据库连接信息
production:
adapter: mysql2
database: redmine
host: localhost
username: root
password: "linuxeye"
encoding: utf8
安装redmine依赖的所有ruby包
cd ..
gem install bundler #注意是在网站根目录下执行
bundle install --without development test rmagick #完成redmine依赖包的安装
bundler是用来管理ruby的包依赖的工具
为Rails生成cookies秘钥
rake generate_secret_token
创建数据库结构
RAILS_ENV=production rake db:migrate
生成缺省数据
RAILS_ENV=production REDMINE_LANG=zh rake redmine:load_default_data
调整文件系统权限
cd /data/wwwroot/redmine
mkdir -p tmp tmp/pdf public/plugin_assets
chown -R www.www /data/wwwroot/redmine
tmp和tmp/pdf (若不存在则创建该路径,用于生成 PDF 文件)；public/plugin_assets (若不存在则创建该路径,plugins资源)
5. 在WEBrick服务上测试Redmine是否安装成功
# vi /etc/passwd #使www用户有bash权限，lnmp脚本安装www用户没有bash权限
www:x:501:501::/home/www:/bin/bash
# su www -c "ruby script/rails server webrick -e production -d"
地址：http://IP:3000 (注意：打开iptables 3000端口号)
缺省管理员用户:
- login: admin
- password: admin
如果验证成功，则继续下面的步骤来使Redmine运行在Apache服务上
6. 配置Redmine在Nginx上运行
结束webrick服务
cd /data/wwwroot/redmine/public/
cp dispatch.fcgi.example dispatch.fcgi
cp htaccess.fcgi.example .htaccess
chown -R www.www ./*
安装Passenger（用于整合Nginx）
gem install passenger
passenger-install-nginx-module
重新编译Nginx
cd ~/lnmp/src
cd nginx-1.6.2
/usr/local/nginx/sbin/nginx -V #查看已经编译参数
#在其后加上--add-module=/usr/local/ruby/lib/ruby/gems/2.1.0/gems/passenger-4.0.57/ext/nginx参数，我的编译参数如下
./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module
--with-http_spdy_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module
--with-http_flv_module --with-ld-opt=-ljemalloc
--add-module=/usr/local/ruby/lib/ruby/gems/2.1.0/gems/passenger-4.0.57/ext/nginx
make
mv /usr/local/nginx/sbin/nginx{,_`date +%m%d`}
cp objscp objs/nginx /usr/local/nginx/sbin/
配置Nginx
vi /usr/local/nginx/conf/nginx.conf#在http {}直接添加
passenger_root /usr/local/ruby/lib/ruby/gems/2.1.0/gems/passenger-4.0.57;
passenger_ruby /usr/local/ruby/bin/ruby;
添加虚拟主机（/usr/local/nginx/conf/vhost/bugs.linuxeye.com.conf）如下：
server {
listen 80;
server_name bugs.linuxeye.com;
access_log /data/wwwlogs/bugs.linuxeye.com_nginx.log combined;
index index.html index.htm index.jsp index.php;
include none.conf;
root /data/wwwroot/redmine/public;
passenger_enabled on;
}
