环境介绍：

CentOS Linux release 7.6.1810 (Core)

MySQL5.7

Redmine 3.3

ruby-2.3.3

Rails 4.2.6

参考文档：http://www.redmine.org/projects/redmine/wiki/RedmineInstall

1. 环境准备

官方的yum源下载软件速度慢，把yum源替换成阿里的yum源，并安装epel源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

yum clean all

yum makecache

安装rvm及ruby

curl -L https://get.rvm.io | bash -s stable

此时会报错，按照返回的提示执行相应的命令

gpg --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3

（替换成你提示的执行命令）

设置Ruby系统环境

source /etc/profile.d/rvm.sh

rvm reload  

rvm install 2.3.3

切换阿里的源

gem source -r https://rubygems.org/

gem source -a http://mirrors.aliyun.com/rubygems/

安装

gem install rake -v 12.0.0

gem install rails -v 4.2.6

安装mysql数据库（5.7）

Wget https://dev.mysql.com/get/mysql80-community-release-el7-2.noarch.rpm

安装mysql源

yum -y install mysql80-community-release-el7-2.noarch.rpm

(注意默认安装的是MySQL8.0，所以安装好yum源后，要修改yum源的配置,把mysql8.0禁掉,开启mysql5.7的源后再进行安装)。

yum repolist enabled | grep mysql.*

yum install mysql-community-server

systemctl start  mysqld.service

运行一下命令查看一下运行状态

systemctl status mysqld.service

查看一下初始密码

grep "password" /var/log/mysqld.log

登录

mysql -uroot -p

修改密码

mysql>ALTER USER 'root'@'localhost' IDENTIFIED BY '****************';

mysql>FLUSH PRIVILEGES;

设置自动启动

systemctl enable mysqld

systemctl daemon-reload

2. 数据库操作

CREATE DATABASE redmine CHARACTER SET utf8mb4;

CREATE USER 'redmine'@'localhost' IDENTIFIED BY 'redmine';

GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost';

3. 更改配置文件

解压软件包redmine-3.3.0.tar.gz

tar xf  redmine-3.3.0.tar.gz -C /opt

cd /opt/redmine-3.3.0

cp  database.yml.example  database.yml

修改database.yml如下内容（这块要仔细，不要乱改数据库名，否则会出问题，最好一致）

production:

adapter: mysql2

database: redmine

host: localhost

username: redmine

password: "redmine"

Redmine使用Bundler管理gem依赖项，需要先安装Bundler

gem install bundler

Then you can install all the gems required by Redmine using the following command:

bundle install --without development test

（执行这个命令后报错，解决办法yum -y install ImageMagick-devel,然后再执行一遍undle install --without development test)

Session store secret generation:

bundle exec rake generate_secret_token

在应用程序根目录下(/opt/redmine-3.3.0)运行以下命令，创建数据库结构:

RAILS_ENV=production bundle exec rake db:migrate

设置数据库默认数据集，通过运行以下命令，在数据库中插入默认配置数据:

RAILS_ENV=production bundle exec rake redmine:load_default_data

输入zh

至此，redmine安装完成。

3.启动redmine

cd /opt/redmine-3.3.0/bin

echo –e  ‘#!/bin/bash\nbundle exec rails server webrick -e production -p 3000 -b 0.0.0.0 -d’  >> start.sh

chmod +x start.sh

./start.sh
