1.安装mysql
sudo apt-get install mysql-server-5.6 mysql-client-5.6
2.修改mysql绑定的127.0.0.1信息
修改文件/etc/mysql/my.cnf
修改完重启
sudo service mysql stop
sudo service mysql start
3.登录数据库确认是否正常
mysql -u root -p
4.创建数据库和用户
CREATE DATABASE redmine CHARACTER SET utf8; CREATE USER ‘redmine‘@‘localhost‘ IDENTIFIED BY ‘my_password‘; GRANT ALL PRIVILEGES ON redmine.* TO ‘redmine‘@‘localhost‘;
5.解压下载后的redmine文件
tar xzvf redmine-2.5.2.tar.gz
6.cp到/opt目录下
sudo cp -Rf redmine-2.5.2 /opt/redmine-2.5.2
7.修改权限
sudo chown -Rf terry:terry redmine-2.5.2/
sudo chmod -Rf 775 redmine-2.5.2/
8.修改数据库连接文件
９．主目录（ｒｅｄｍｉｎｅ解压后根目录）执行ｔｏｋｅｎ信息
rake generate_secret_token（此命令出现的问题见后面的问题处理）
１０．创建数据库结构
RAILS_ENV=production rake db:migrate
此命令执行一路畅通
11. 初始化数据
RAILS_ENV=production rake redmine:load_default_data
此命令执行一路畅通,同时运行的过程中选择语言，我输入的是ｚｈ
12.测试安装是否成功
ruby script/rails server webrick -e production
测试通过
１３．登录系统
使用管理员admin/admin登录系统
