1.redmine网站下载Redmine4.2.0的安装包;
2.拷贝Redmine4.2.0的安装包到ubuntu工作目录，并解压缩
3.移植redmine解压目录到/opt目录
4.配置Redmine数据库，拷贝redmine解压目录下的config目录下的database.yml.example，为database.yml文件，并进行第1节的配置，具体如下所述：
cp database.yml.example database.yml
Question1: thsj@thsj-pc:/opt/redmine-4.2.0$ sudo gem install bundler
Fetching: bundler-2.4.19.gem (100%)
ERROR: Error installing bundler:
The last version of bundler (>= 0) to support your Ruby & RubyGems was 2.3.26. Try installing it with `gem install bundler -v 2.3.26`
bundler requires Ruby version >= 2.6.0. The current ruby version is 2.5.0.
5.进入redmine目录，安装Ruby依赖项，如下图所示：

6.更改默认gem源，默认gem源地址为：https://rubygems.org/，修改为国内gem源地址：https://gems.ruby-china.com。提高安装Ruby依赖项的速度，缩短安装时间。修改后，查看当前gem源。如下图所示：
gem sources --remove https://rubygems.org/
gem source -a https://gems.ruby-china.com
gem source -l
7.进入redmine目录，安装Ruby依赖项，（注意：切换到https://gems.ruby-china.com）
thsj@thsj-pc:/opt/redmine-4.2.0$ vim Gemfile .更改默认Gemfile源
sudo gem install bundler -v 2.3.20
sudo bundle config set --local without 'development test postgresql sqlite'
sudo bundle install
（该处命令执行时间较长，可能达到十几分钟）

Question3:
thsj@thsj-pc:/opt/redmine-4.2.0$ sudo bundle exec rake generate_secret_token
Your RubyGems version (2.7.6) has a bug that prevents `required_ruby_version` from working for Bundler. Any scripts that use `gem install bundler` will break as soon as Bundler drops support for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning by running `gem update --system 3.2.3`

Answer:
sudo apt-get install mysql-server mysql-client
sudo mysql -u root -p
mysql>create database redmine;
mysql>alter database redmine character set utf8;
添加用户redmine并刷行权限：
mysql>grant all privileges on redmine.* to redmine@"localhost" identified by 'l' with grant option;
mysql>flush privileges;
9.初始化数据表配置，配置中文zh：
bundle exec rake redmine:load_default_data RAILS_ENV=production REDMINE_LANG=zh
10.设置本地ip地址（192.168.0.13），如果设置了固定IP地址，可以跳过该节.
sudo ifconfig enp0s3 192.168.0.13
11.使用指令启动redmine服务，指定监听端口30010：
bundle exec rails server webrick -e production -b 0.0.0.0 -p 30010
12.在浏览器中输入192.168.0.13:30010，即可进入redmine登录界面，如下图所示：
13.redmine默认用户为：admin，密码：admin，输入用户密码即可登录进入，首次登录redmine需要进行密码修改。
