下载redmine-5.1.2.tar.gz，上传到/usr/local/目录下

1. cd /usr/local/

2. tar -zxf redmine-5.1.2.tar.gz

3. cd redmine-5.1.2

4. cp config/database.yml.example config/database.yml

5. 配置数据连接

#编辑配置文件
vi config/database.yml
#修改后的内容如下
 
production:
  adapter: mysql2
  database: redmine
  host: localhost
  username: root
  password: test1234
  # Use "utf8" instead of "utfmb4" for MySQL prior to 5.7.7
  encoding: utf8mb4
  variables:
    # Recommended `transaction_isolation` for MySQL to avoid concurrency issues is
    # `READ-COMMITTED`.
    # In case of MySQL lower than 8, the variable name is `tx_isolation`.
    # See https://www.redmine.org/projects/redmine/wiki/MySQL_configuration
    transaction_isolation: "READ-COMMITTED"
 其它全部注释

        6.安装依赖

yum install -y gcc gcc-c++ make automake cmake autoconf curl-devel openssl-devel zlib-devel httpd-devel apr-devel apr-util-devel mysql-devel ruby ruby-devel rubygems

        7.安装rvm

curl -L get.rvm.io | bash -s stable

        结果：

Warning, RVM 1.26.0 introduces signed releases and automated check of signatures when GPG software found.
Assuming you trust Michal Papis import the mpapis public key (downloading the signatures).
 
GPG signature verification failed for '/usr/local/rvm/archives/rvm-1.26.11.tgz' - 'https://github.com/rvm/rvm/releases/download/1.26.11/1.26.11.tar.gz.asc'!
try downloading the signatures:
 
    gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
 
or if it fails:
 
    command curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
 
the key can be compared with:
 
    https://rvm.io/mpapis.asc
    https://keybase.io/mpapis

 那么复制

gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

再次执行

curl -L get.rvm.io | bash -s stable

Creating group 'rvm'
Installing RVM to /usr/local/rvm/
Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,
    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
    in all your open shell windows, in rare cases you need to reopen all shell windows.
  * Please do NOT forget to add your users to the rvm group.
     The installer no longer auto-adds root or users to the rvm group. Admins must do this.
     Also, please note that group memberships are ONLY evaluated at login time.
     This means that users must log out then back in before group membership takes effect!
Thanks for installing RVM [0m

执行

echo "source /etc/profile.d/rvm.sh" >> ~/.bashrc && source /etc/profile.d/rvm.sh

RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /usr/local/redmine-5.1.2/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

Unknown ruby interpreter version (do not know how to handle): >=2.7.0,<3.3.0.

Post-install message from rubyzip:
RubyZip 3.0 is coming!
**********************

The public API of some Rubyzip classes has been modernized to use named
parameters for optional arguments. Please check your usage of the
following classes:
  * `Zip::File`
  * `Zip::Entry`
  * `Zip::InputStream`
  * `Zip::OutputStream`

Please ensure that your Gemfiles and .gemspecs are suitably restrictive
to avoid an unexpected breakage when 3.0 is released (e.g. ~> 2.3.0).
See https://github.com/rubyzip/rubyzip for details. The Changelog also
lists other enhancements and bugfixes that have been implemented since
version 2.3.0.
